In Light of CipherTrace, Let's Talk Opsec

So I was very skeptical at first, but Dave maybe convinced me about 10% that they have some level of capability in the direction they're suggesting. The techniques are stuff we've known, and it would require large computational resources, combined with loads of offchain data, but maybe they have taken efforts to the next level. It's my belief that govts and banks really dislike Monero. So with that in mind lets give them some small benefit of the doubt and take some creative license:
Again, they would need some serious computational power and off-chain data feeds. I also imagine that their models suffer from time-decay, especially without a constant stream of hueristic data. Notice at the end he emphasized opsec. Here, I really do believe him. So finally, lets talk opsec.
I have mixed feelings on this. One of our selling points is default privacy made easy. A lot of what I wrote above doesn't exactly sound simple. On the other hand, crypto is about self responsibility and knowledge. Most people ought to have been adhering to at least the basics (ToVPN, new subaddresses, run your own node). But even if we give CT the benefit of the doubt, the following is still true:
Newb use of Monero is far more private than ninja use of Bitcoin.

The Privacy Coin Guide Part 1

As interest picks up in crypto again, I want to share this post I made on privacy coins again to just give the basics of their evolution. This is only part 1, and parts 2 and 3 are not available in this format, but this part is informative and basic.
If you’re looking for a quick and easy way to assess what the best privacy coin in the current space is, which has the best features, or which is most likely to give high returns, then this is not that guide. My goal is to give you the power to make your own decisions, to clearly state my biases, and educate. I really wanted to understand this niche of the crypto-space due to my background and current loyalties[1], and grasp the nuances of the features, origins and timelines of technologies used in privacy coins, while not being anything close to a developer myself. This is going to be a 3-part series, starting with an overview and basic review of the technology, then looking at its implications, and ending with why I like a specific project. It might be mildly interesting or delightfully educational. Cryptocurrencies are young and existing privacy coins are deploying technology that is a work in progress. This series assumes a basic understanding of how blockchains work, specifically as used in cryptocurrencies. If you don’t have that understanding, might I suggest that you get it? [2],[3],[4] Because cryptocurrencies have a long way to go before reaching their end-game: when the world relies on the technology without understanding it. So, shall we do a deep dive into the privacy coin space?

FIRST THERE WAS BITCOIN

Cryptocurrencies allow you to tokenize value and track its exchange between hands over time, with transaction information verified by a distributed network of users. The most famous version of a cryptocurrency in use is Bitcoin, defined as peer-to-peer electronic cash. [5] Posted anonymously in 2008, the whitepaper seemed to be in direct response to the global financial meltdown and public distrust of the conventional banking and financing systems. Although cryptographic techniques are used in Bitcoin to ensure that (i) only the owner of a specific wallet has the authority to spend funds from that wallet, (ii) the public address is linked but cannot be traced by a third party to the private address (iii) the information is stored via cryptographic hashing in a merkle tree structure to ensure data integrity, the actual transaction information is publicly visible on the blockchain and can be traced back to the individual through chain analysis.[6] This has raised fears of possible financial censorship or the metaphorical tainting of money due to its origination point, as demonstrated in the Silk Road marketplace disaster.[7] This can happen because fiat money is usually exchanged for cryptocurrency at some point, as crypto-enthusiasts are born in the real world and inevitably cash out. There are already chain analysis firms and software that are increasingly efficient at tracking transactions on the Bitcoin blockchain.[8] This lack of privacy is one of the limitations of Bitcoin that has resulted in the creation of altcoins that experiment with the different features a cryptocurrency can have. Privacy coins are figuring out how to introduce privacy in addition to the payment network. The goal is to make the cryptocurrency fungible, each unit able to be exchanged for equal value without knowledge of its transaction history – like cash, while being publicly verifiable on a decentralized network. In other words, anyone can add the math up without being able to see the full details. Some privacy solutions and protocols have popped up as a result:

CRYPTONOTE – RING SIGNATURES AND STEALTH ADDRESSES

Used in: Monero and Particl as its successor RING-CT, Bytecoin
In December 2012, CryptoNote introduced the use of ring signatures and stealth addresses (along with other notable features such as its own codebase) to improve cryptocurrency privacy.[9] An updated CryptoNote version 2 came in October 2013 [10](though there is some dispute over this timeline [11]), also authored under the name Nicolas van Saberhagen. Ring signatures hide sender information by having the sender sign a transaction using a signature that could belong to multiple users. This makes a transaction untraceable. Stealth addresses allow a receiver to give a single address which generates a different public address for funds to be received at each time funds are sent to it. That makes a transaction unlinkable. In terms of privacy, CryptoNote gave us a protocol for untraceable and unlinkable transactions. The first implementation of CryptoNote technology was Bytecoin in March 2014 (timeline disputed [12]), which spawned many children (forks) in subsequent years, a notable example being Monero, based on CryptoNote v2 in April 2014.
RING SIGNATURES and STEALTH ADDRESSES

PROS

– Provides sender and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume
-Does not hide transaction information if not combined with another protocol.

COINJOIN

Used in: Dash
Bitcoin developer Gregory Maxwell proposed a set of solutions to bring privacy to Bitcoin and cryptocurrencies, the first being CoinJoin (January 28 – Aug 22, 2013).[13],[14] CoinJoin (sometimes called CoinSwap) allows multiple users to combine their transactions into a single transaction, by receiving inputs from multiple users, and then sending their outputs to the multiple users, irrespective of who in the group the inputs came from. So, the receiver will get whatever output amount they were supposed to, but it cannot be directly traced to its origination input. Similar proposals include Coinshuffle in 2014 and Tumblebit in 2016, building on CoinJoin but not terribly popular [15],[16]. They fixed the need for a trusted third party to ‘mix’ the transactions. There are CoinJoin implementations that are being actively worked on but are not the most popular privacy solutions of today. A notable coin that uses CoinJoin technology is Dash, launched in January 2014, with masternodes in place of a trusted party.
COINJOIN

PROS

– Provides sender and receiver privacy
– Easy to implement on any cryptocurrency
– Lightweight
– Greater scalability with bulletproofs
– Mature technology

CONS

– Least anonymous privacy solution. Transaction amounts can be calculated
– Even without third-party mixer, depends on wealth centralization of masternodes

ZEROCOIN

Used in: Zcoin, PIVX
In May 2013, the Zerocoin protocol was introduced by John Hopkins University professor Matthew D. Green and his graduate students Ian Miers and Christina Garman.[17] In response to the need for use of a third party to do CoinJoin, the Zerocoin proposal allowed for a coin to be destroyed and remade in order to erase its history whenever it is spent. Zero-knowledge cryptography and zero-knowledge proofs are used to prove that the new coins for spending are being appropriately made. A zero-knowledge proof allows one party to prove to another that they know specific information, without revealing any information about it, other than the fact that they know it. Zerocoin was not accepted by the Bitcoin community as an implementation to be added to Bitcoin, so a new cryptocurrency had to be formed. Zcoin was the first cryptocurrency to implement the Zerocoin protocol in 2016. [18]
ZEROCOIN

PROS

– Provides sender and receiver privacy
– Supply can be audited
– Relatively mature technology
– Does not require a third-party

CONS

– Requires trusted setup (May not be required with Sigma protocol)
– Large proof sizes (not lightweight)
– Does not provide full privacy for transaction amounts

ZEROCASH

Used in: Zcash, Horizen, Komodo, Zclassic, Bitcoin Private
In May 2014, the current successor to the Zerocoin protocol, Zerocash, was created, also by Matthew Green and others (Eli Ben-Sasson, Alessandro Chiesa, Christina Garman, Matthew Green, Ian Miers, Eran Tromer, Madars Virza).[19] It improved upon the Zerocoin concept by taking advantage of zero-knowledge proofs called zk-snarks (zero knowledge succinct non-interactive arguments of knowledge). Unlike Zerocoin, which hid coin origins and payment history, Zerocash was faster, with smaller transaction sizes, and hides transaction information on the sender, receiver and amount. Zcash is the first cryptocurrency to implement the Zerocash protocol in 2016. [20]
ZEROCASH

PROS

– Provides full anonymity. Sender, receiver and amount hidden.
– Privacy can be default?
– Fast due to small proof sizes.
– Payment amount can be optionally disclosed for auditing
– Does not require any third-party

CONS

– Requires trusted setup. (May be improved with zt-starks technology)
– Supply cannot be audited. And coins can potentially be forged without proper implementation.
– Private transactions computationally intensive (improved with Sapling upgrade)

CONFIDENTIAL TRANSACTIONS

Used in: Monero and Particl with Ring Signatures as RING-CT
The next proposal from Maxwell was that of confidential transactions, proposed in June 2015 as part of the Sidechain Elements project from Blockstream, where Maxwell was Chief Technical Officer.[21],[22] It proposed to hide the transaction amount and asset type (e.g. deposits, currencies, shares), so that only the sender and receiver are aware of the amount, unless they choose to make the amount public. It uses homomorphic encryption[23] to encrypt the inputs and outputs by using blinding factors and a kind of ring signature in a commitment scheme, so the amount can be ‘committed’ to, without the amount actually being known. I’m terribly sorry if you now have the urge to go and research exactly what that means. The takeaway is that the transaction amount can be hidden from outsiders while being verifiable.
CONFIDENTIAL TRANSACTIONS

PROS

– Hides transaction amounts
– Privacy can be default
– Mature technology
– Does not require any third-party

CONS

– Only provides transaction amount privacy when used alone

RING-CT

Used in: Monero, Particl
Then came Ring Confidential transactions, proposed by Shen-Noether of Monero Research Labs in October 2015.[24] RingCT combines the use of ring signatures for hiding sender information, with the use of confidential transactions (which also uses ring signatures) for hiding amounts. The proposal described a new type of ring signature, A Multi-layered Linkable Spontaneous Anonymous Group signature which “allows for hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation”.[25] RingCT was implemented in Monero in January 2017 and made mandatory after September 2017.
RING -CONFIDENTIAL TRANSACTIONS

PROS

– Provides full anonymity. Hides transaction amounts and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume

MIMBLEWIMBLE

Used in: Grin
Mimblewimble was proposed in July 2016 by pseudonymous contributor Tom Elvis Jedusorand further developed in October 2016 by Andrew Poelstra.[26],[27] Mimblewimble is a “privacy and fungibility focused cryptocoin transaction structure proposal”.[28] The key words are transaction structure proposal, so the way the blockchain is built is different, in order to accommodate privacy and fungibility features. Mimblewimble uses the concept of Confidential transactions to keep amounts hidden, looks at private keys and transaction information to prove ownership of funds rather than using addresses, and bundles transactions together instead of listing them separately on the blockchain. It also introduces a novel method of pruning the blockchain. Grin is a cryptocurrency in development that is applying Mimblewimble. Mimblewimble is early in development and you can understand it more here [29].
MIMBLEWIMBLE

PROS

– Hides transaction amounts and receiver privacy
– Privacy is on by default
– Lightweight
– No public addresses?

CONS

– Privacy not very effective without high volume
– Sender and receiver must both be online
– Relatively new technology

ZEXE

Fresh off the minds of brilliant cryptographers (Sean Bowe, Alessandro Chiesa, Matthew Green, Ian Miers, Pratyush Mishra, Howard Wu), in October 2018 Zexe proposed a new cryptographic primitive called ‘decentralized private computation.[30] It allows users of a decentralized ledger to “execute offline computations that result in transactions”[31], but also keeps transaction amounts hidden and allows transaction validation to happen at any time regardless of computations being done online. This can have far reaching implications for privacy coins in the future. Consider cases where transactions need to be automatic and private, without both parties being present.

NETWORK PRIVACY

Privacy technologies that look at network privacy as nodes communicate with each other on the network are important considerations, rather than just looking at privacy on the blockchain itself. Anonymous layers encrypt and/or reroute data as it moves among peers, so it is not obvious who they originate from on the network. They are used to protect against surveillance or censorship from ISPs and governments. The Invisible Internet Project (I2P) is an anonymous network layer that uses end to end encryption for peers on a network to communicate with each other.[32] Its history dates back to 2003. Kovri is a Monero created implementation of I2P.[33] The Onion Router (Tor) is another anonymity layer [34]) that Verge is a privacy cryptocurrency that uses. But its historical link to the US government may be is concerning to some[35]. Dandelion transaction relay is also an upcoming Bitcoin improvement proposal (BIP) that scrambles IP data that will provide network privacy for Bitcoin as transaction and other information is transmitted.[36],[37],[38]

UPCOMING

Monero completed bulletproofs protocol updates that reduce RINGCT transaction sizes and thus transaction fee costs. (Bulletproofs are a replacement for range proofs used in confidential transactions that aid in encrypting inputs and outputs by making sure they add to zero).
Sigma Protocol – being actively researched by Zcoin team as of 2018 to replace Zerocoin protocol so that a trusted setup is not required.[39] There is a possible replacement for zk-snarks, called zk-starks, another form of zero-knowledge proof technology, that may make a trusted set-up unnecessary for zero-knowledege proof coins.[40]

PART 1 CONCLUSION OF THE PRIVACY COIN GUIDE ON THE TECHNOLOGY BEHIND PRIVACY COINS

Although Bitcoin is still a groundbreaking technology that gives us a trust-less transaction system, it has failed to live up to its expectations of privacy. Over time, new privacy technologies have arrived and are arriving with innovative and exciting solutions for Bitcoin’s lack of fungibility. It is important to note that these technologies are built on prior research and application, but we are considering their use in cryptocurrencies. Protocols are proposed based on cryptographic concepts that show how they would work, and then developers actually implement them. Please note that I did not include the possibility of improper implementation as a disadvantage, and the advantages assume that the technical development is well done. A very important point is that coins can also adapt new privacy technologies as their merits become obvious, even as they start with a specific privacy protocol. Furthermore, I am, unfortunately, positive that this is not an exhaustive overview and I am only covering publicized solutions. Next, we’ll talk more about the pros and cons and give an idea of how the coins can be compared.

There's a video version that can be watched, and you can find out how to get the second two parts if you want on my website (video link on the page): https://cryptoramble.com/guide-on-privacy-coins/

The next proposal from Maxwell was that of confidential transactions, proposed in June 2015 as part of the Sidechain Elements project from Blockstream, where Maxwell was Chief Technical Officer.[21],[22] It proposed to hide the transaction amount and asset type (e.g. deposits, currencies, shares), so that only the sender and receiver are aware of the amount, unless they choose to make the amount public. It uses homomorphic encryption[23] to encrypt the inputs and outputs by using blinding factors and a kind of ring signature in a commitment scheme, so the amount can be ‘committed’ to, without the amount actually being known. I’m terribly sorry if you now have the urge to go and research exactly what that means. The takeaway is that the transaction amount can be hidden from outsiders while being verifiable.
CONFIDENTIAL TRANSACTIONS

PROS

– Hides transaction amounts
– Privacy can be default
– Mature technology
– Does not require any third-party

CONS

– Only provides transaction amount privacy when used alone

RING-CT

Used in: Monero, Particl
Then came Ring Confidential transactions, proposed by Shen-Noether of Monero Research Labs in October 2015.[24] RingCT combines the use of ring signatures for hiding sender information, with the use of confidential transactions (which also uses ring signatures) for hiding amounts. The proposal described a new type of ring signature, A Multi-layered Linkable Spontaneous Anonymous Group signature which “allows for hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation”.[25] RingCT was implemented in Monero in January 2017 and made mandatory after September 2017.
RING -CONFIDENTIAL TRANSACTIONS

PROS

– Provides full anonymity. Hides transaction amounts and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume

MIMBLEWIMBLE

Used in: Grin
Mimblewimble was proposed in July 2016 by pseudonymous contributor Tom Elvis Jedusorand further developed in October 2016 by Andrew Poelstra.[26],[27] Mimblewimble is a “privacy and fungibility focused cryptocoin transaction structure proposal”.[28] The key words are transaction structure proposal, so the way the blockchain is built is different, in order to accommodate privacy and fungibility features. Mimblewimble uses the concept of Confidential transactions to keep amounts hidden, looks at private keys and transaction information to prove ownership of funds rather than using addresses, and bundles transactions together instead of listing them separately on the blockchain. It also introduces a novel method of pruning the blockchain. Grin is a cryptocurrency in development that is applying Mimblewimble. Mimblewimble is early in development and you can understand it more here [29].
MIMBLEWIMBLE

PROS

– Hides transaction amounts and receiver privacy
– Privacy is on by default
– Lightweight
– No public addresses?

CONS

– Privacy not very effective without high volume
– Sender and receiver must both be online
– Relatively new technology

ZEXE

Fresh off the minds of brilliant cryptographers (Sean Bowe, Alessandro Chiesa, Matthew Green, Ian Miers, Pratyush Mishra, Howard Wu), in October 2018 Zexe proposed a new cryptographic primitive called ‘decentralized private computation.[30] It allows users of a decentralized ledger to “execute offline computations that result in transactions”[31], but also keeps transaction amounts hidden and allows transaction validation to happen at any time regardless of computations being done online. This can have far reaching implications for privacy coins in the future. Consider cases where transactions need to be automatic and private, without both parties being present.

NETWORK PRIVACY

Privacy technologies that look at network privacy as nodes communicate with each other on the network are important considerations, rather than just looking at privacy on the blockchain itself. Anonymous layers encrypt and/or reroute data as it moves among peers, so it is not obvious who they originate from on the network. They are used to protect against surveillance or censorship from ISPs and governments. The Invisible Internet Project (I2P) is an anonymous network layer that uses end to end encryption for peers on a network to communicate with each other.[32] Its history dates back to 2003. Kovri is a Monero created implementation of I2P.[33] The Onion Router (Tor) is another anonymity layer [34]) that Verge is a privacy cryptocurrency that uses. But its historical link to the US government may be is concerning to some[35]. Dandelion transaction relay is also an upcoming Bitcoin improvement proposal (BIP) that scrambles IP data that will provide network privacy for Bitcoin as transaction and other information is transmitted.[36],[37],[38]

UPCOMING

Monero completed bulletproofs protocol updates that reduce RINGCT transaction sizes and thus transaction fee costs. (Bulletproofs are a replacement for range proofs used in confidential transactions that aid in encrypting inputs and outputs by making sure they add to zero).
Sigma Protocol – being actively researched by Zcoin team as of 2018 to replace Zerocoin protocol so that a trusted setup is not required.[39] There is a possible replacement for zk-snarks, called zk-starks, another form of zero-knowledge proof technology, that may make a trusted set-up unnecessary for zero-knowledege proof coins.[40]

PART 1 CONCLUSION OF THE PRIVACY COIN GUIDE ON THE TECHNOLOGY BEHIND PRIVACY COINS

Although Bitcoin is still a groundbreaking technology that gives us a trust-less transaction system, it has failed to live up to its expectations of privacy. Over time, new privacy technologies have arrived and are arriving with innovative and exciting solutions for Bitcoin’s lack of fungibility. It is important to note that these technologies are built on prior research and application, but we are considering their use in cryptocurrencies. Protocols are proposed based on cryptographic concepts that show how they would work, and then developers actually implement them. Please note that I did not include the possibility of improper implementation as a disadvantage, and the advantages assume that the technical development is well done. A very important point is that coins can also adapt new privacy technologies as their merits become obvious, even as they start with a specific privacy protocol. Furthermore, I am, unfortunately, positive that this is not an exhaustive overview and I am only covering publicized solutions. Next, we’ll talk more about the pros and cons and give an idea of how the coins can be compared.

The Privacy Coin Guide Part 1

As interest picks up in crypto again, I want to share this post I made on privacy coins again to just give the basics of their evolution. This is only part 1, and parts 2 and 3 are not available in this format, but this part is informative and basic.
If you’re looking for a quick and easy way to assess what the best privacy coin in the current space is, which has the best features, or which is most likely to give high returns, then this is not that guide. My goal is to give you the power to make your own decisions, to clearly state my biases, and educate. I really wanted to understand this niche of the crypto-space due to my background and current loyalties[1], and grasp the nuances of the features, origins and timelines of technologies used in privacy coins, while not being anything close to a developer myself. This is going to be a 3-part series, starting with an overview and basic review of the technology, then looking at its implications, and ending with why I like a specific project. It might be mildly interesting or delightfully educational. Cryptocurrencies are young and existing privacy coins are deploying technology that is a work in progress. This series assumes a basic understanding of how blockchains work, specifically as used in cryptocurrencies. If you don’t have that understanding, might I suggest that you get it? [2],[3],[4] Because cryptocurrencies have a long way to go before reaching their end-game: when the world relies on the technology without understanding it. So, shall we do a deep dive into the privacy coin space?

FIRST THERE WAS BITCOIN

Cryptocurrencies allow you to tokenize value and track its exchange between hands over time, with transaction information verified by a distributed network of users. The most famous version of a cryptocurrency in use is Bitcoin, defined as peer-to-peer electronic cash. [5] Posted anonymously in 2008, the whitepaper seemed to be in direct response to the global financial meltdown and public distrust of the conventional banking and financing systems. Although cryptographic techniques are used in Bitcoin to ensure that (i) only the owner of a specific wallet has the authority to spend funds from that wallet, (ii) the public address is linked but cannot be traced by a third party to the private address (iii) the information is stored via cryptographic hashing in a merkle tree structure to ensure data integrity, the actual transaction information is publicly visible on the blockchain and can be traced back to the individual through chain analysis.[6] This has raised fears of possible financial censorship or the metaphorical tainting of money due to its origination point, as demonstrated in the Silk Road marketplace disaster.[7] This can happen because fiat money is usually exchanged for cryptocurrency at some point, as crypto-enthusiasts are born in the real world and inevitably cash out. There are already chain analysis firms and software that are increasingly efficient at tracking transactions on the Bitcoin blockchain.[8] This lack of privacy is one of the limitations of Bitcoin that has resulted in the creation of altcoins that experiment with the different features a cryptocurrency can have. Privacy coins are figuring out how to introduce privacy in addition to the payment network. The goal is to make the cryptocurrency fungible, each unit able to be exchanged for equal value without knowledge of its transaction history – like cash, while being publicly verifiable on a decentralized network. In other words, anyone can add the math up without being able to see the full details. Some privacy solutions and protocols have popped up as a result:

CRYPTONOTE – RING SIGNATURES AND STEALTH ADDRESSES

Used in: Monero and Particl as its successor RING-CT, Bytecoin
In December 2012, CryptoNote introduced the use of ring signatures and stealth addresses (along with other notable features such as its own codebase) to improve cryptocurrency privacy.[9] An updated CryptoNote version 2 came in October 2013 [10](though there is some dispute over this timeline [11]), also authored under the name Nicolas van Saberhagen. Ring signatures hide sender information by having the sender sign a transaction using a signature that could belong to multiple users. This makes a transaction untraceable. Stealth addresses allow a receiver to give a single address which generates a different public address for funds to be received at each time funds are sent to it. That makes a transaction unlinkable. In terms of privacy, CryptoNote gave us a protocol for untraceable and unlinkable transactions. The first implementation of CryptoNote technology was Bytecoin in March 2014 (timeline disputed [12]), which spawned many children (forks) in subsequent years, a notable example being Monero, based on CryptoNote v2 in April 2014.
RING SIGNATURES and STEALTH ADDRESSES

PROS

– Provides sender and receiver privacy
– Privacy can be default
– Mature technology
– Greater scalability with bulletproofs
– Does not require any third-party

CONS

– Privacy not very effective without high volume
-Does not hide transaction information if not combined with another protocol.

COINJOIN

Used in: Dash
Bitcoin developer Gregory Maxwell proposed a set of solutions to bring privacy to Bitcoin and cryptocurrencies, the first being CoinJoin (January 28 – Aug 22, 2013).[13],[14] CoinJoin (sometimes called CoinSwap) allows multiple users to combine their transactions into a single transaction, by receiving inputs from multiple users, and then sending their outputs to the multiple users, irrespective of who in the group the inputs came from. So, the receiver will get whatever output amount they were supposed to, but it cannot be directly traced to its origination input. Similar proposals include Coinshuffle in 2014 and Tumblebit in 2016, building on CoinJoin but not terribly popular [15],[16]. They fixed the need for a trusted third party to ‘mix’ the transactions. There are CoinJoin implementations that are being actively worked on but are not the most popular privacy solutions of today. A notable coin that uses CoinJoin technology is Dash, launched in January 2014, with masternodes in place of a trusted party.
COINJOIN

PROS

– Provides sender and receiver privacy
– Easy to implement on any cryptocurrency
– Lightweight
– Greater scalability with bulletproofs
– Mature technology

CONS

– Least anonymous privacy solution. Transaction amounts can be calculated
– Even without third-party mixer, depends on wealth centralization of masternodes

ZEROCOIN

Used in: Zcoin, PIVX
In May 2013, the Zerocoin protocol was introduced by John Hopkins University professor Matthew D. Green and his graduate students Ian Miers and Christina Garman.[17] In response to the need for use of a third party to do CoinJoin, the Zerocoin proposal allowed for a coin to be destroyed and remade in order to erase its history whenever it is spent. Zero-knowledge cryptography and zero-knowledge proofs are used to prove that the new coins for spending are being appropriately made. A zero-knowledge proof allows one party to prove to another that they know specific information, without revealing any information about it, other than the fact that they know it. Zerocoin was not accepted by the Bitcoin community as an implementation to be added to Bitcoin, so a new cryptocurrency had to be formed. Zcoin was the first cryptocurrency to implement the Zerocoin protocol in 2016. [18]
ZEROCOIN

PROS

– Provides sender and receiver privacy
– Supply can be audited
– Relatively mature technology
– Does not require a third-party

CONS

– Requires trusted setup (May not be required with Sigma protocol)
– Large proof sizes (not lightweight)
– Does not provide full privacy for transaction amounts

ZEROCASH

Used in: Zcash, Horizen, Komodo, Zclassic, Bitcoin Private
In May 2014, the current successor to the Zerocoin protocol, Zerocash, was created, also by Matthew Green and others (Eli Ben-Sasson, Alessandro Chiesa, Christina Garman, Matthew Green, Ian Miers, Eran Tromer, Madars Virza).[19] It improved upon the Zerocoin concept by taking advantage of zero-knowledge proofs called zk-snarks (zero knowledge succinct non-interactive arguments of knowledge). Unlike Zerocoin, which hid coin origins and payment history, Zerocash was faster, with smaller transaction sizes, and hides transaction information on the sender, receiver and amount. Zcash is the first cryptocurrency to implement the Zerocash protocol in 2016. [20]
ZEROCASH

PROS

– Provides full anonymity. Sender, receiver and amount hidden.
– Privacy can be default?
– Fast due to small proof sizes.
– Payment amount can be optionally disclosed for auditing
– Does not require any third-party

CONS

– Requires trusted setup. (May be improved with zt-starks technology)
– Supply cannot be audited. And coins can potentially be forged without proper implementation.
– Private transactions computationally intensive (improved with Sapling upgrade)

The Invisible Internet Project (I2P) is an anonymous network layer that uses end to end encryption for peers on a network to communicate with each other.[32] Its history dates back to 2003. Kovri is a Monero created implementation of I2P.[33] The Onion Router (Tor) is another anonymity layer [34]) that Verge is a privacy cryptocurrency that uses. But its historical link to the US government may be is concerning to some[35]. Dandelion transaction relay is also an upcoming Bitcoin improvement proposal (BIP) that scrambles IP data that will provide network privacy for Bitcoin as transaction and other information is transmitted.[36],[37],[38]

UPCOMING

Monero completed bulletproofs protocol updates that reduce RINGCT transaction sizes and thus transaction fee costs. (Bulletproofs are a replacement for range proofs used in confidential transactions that aid in encrypting inputs and outputs by making sure they add to zero).
Sigma Protocol – being actively researched by Zcoin team as of 2018 to replace Zerocoin protocol so that a trusted setup is not required.[39] There is a possible replacement for zk-snarks, called zk-starks, another form of zero-knowledge proof technology, that may make a trusted set-up unnecessary for zero-knowledege proof coins.[40]

PART 1 CONCLUSION OF THE PRIVACY COIN GUIDE ON THE TECHNOLOGY BEHIND PRIVACY COINS

Although Bitcoin is still a groundbreaking technology that gives us a trust-less transaction system, it has failed to live up to its expectations of privacy. Over time, new privacy technologies have arrived and are arriving with innovative and exciting solutions for Bitcoin’s lack of fungibility. It is important to note that these technologies are built on prior research and application, but we are considering their use in cryptocurrencies. Protocols are proposed based on cryptographic concepts that show how they would work, and then developers actually implement them. Please note that I did not include the possibility of improper implementation as a disadvantage, and the advantages assume that the technical development is well done. A very important point is that coins can also adapt new privacy technologies as their merits become obvious, even as they start with a specific privacy protocol. Furthermore, I am, unfortunately, positive that this is not an exhaustive overview and I am only covering publicized solutions. Next, we’ll talk more about the pros and cons and give an idea of how the coins can be compared.

There's a video version that can be watched, and you can find out how to get the second two parts if you want on my website (video link on the page): https://cryptoramble.com/guide-on-privacy-coins/

ColossusXT Q2 2020 AMA Ends!

Thank you for being a part of the ColossusXT Q2 2020 AMA! Below we will summarize the questions and answers. The team responded to 46 questions! If your question was not included, it may have been answered in a previous question or AMA. The ColossusXT team will do a Reddit AMA at the end of every quarter.
The winner of the AMA contest is: ookhimself
Congratulations. I will send you a DM on Reddit.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Why does your blockchain exist and what makes it unique?
A: ColossusXT exists to provide an energy-efficient method of supercomputing. ColossusXT is unique in many ways. Some coins have 1 layer of privacy. ColossusXT and the Colossus Grid will utilize 2 layers of privacy through Obfuscation Zerocoin Protocol, and I2P and these will protect users of the Colossus Grid as they utilize the grid resources. There are also Masternodes and Proof of Stake which both can contribute to reducing 51% attacks, along with instant transactions and zero-fee transactions. This protection is paramount as ColossusXT evolves into the Colossus Grid. Grid Computing will have a pivotal role throughout the world, and what this means is that users will begin to experience the Internet as a seamless computational universe. Software applications, databases, sensors, video, and audio streams-all will be reborn as services that live in cyberspace, assembling, and reassembling themselves on the fly to meet the tasks at hand. Once plugged into the grid, a desktop machine will draw computational horsepower from all the other computers on the grid.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: What is the Colossus Grid?
A: ColossusXT is an anonymous blockchain through obfuscation, along with utilization of I2P (Armis). These features will protect end-user privacy as ColossusXT evolves into the Colossus Grid. The Colossus Grid will connect devices in a peer-to-peer network enabling users and applications to rent the cycles and storage of other users’ machines. This marketplace of computing power and storage will exclusively run on COLX currency. These resources will be used to complete tasks requiring any amount of computation time and capacity, or allow end-users to store data anonymously across the COLX decentralized network. Today, such resources are supplied by entities such as centralized cloud providers which are constrained by closed networks, proprietary payment systems, and hard-coded provisioning operations. Any user ranging from a single PC owner to a large data center can share resources through Colossus Grid and get paid in COLX for their contributions. Renters of computing power or storage space, on the other hand, may do so at low prices compared to the usual market prices because they are only using resources that already exist.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Is there any estimated date for the grid? What will set you apart from the opposition?
A: We are hoping to have something released for the community in Q4 this year. The difference between other competitors is that ColossusXT is putting consumer privacy first and we’re actively in the process of working with federal and state agencies in the United States.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How do you plan to get people to implement the technology? At your current rate of development, when do you foresee a minimum viable product being available?
A: We have been strategically networking with businesses, and we are currently undergoing the verification process in the United States to make bids on federal and state projects. We are working on an MVP and our goal is to have at least a portion of the Colossus Grid ready by Q4 2020.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: When we can expect any use-case for COLX? A company or service that uses COLX for its activities/tasks.
A: We’re aiming for Q4 of this year to have an MVP, throughout 2021 we will be strategically making bids on federal and state contracts in the United States with a goal to expand operations exponentially.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Are there any plans to be listed on the more prominent exchanges e.g binance, kraken?
A: Yes, we have applied to some of these exchanges that are considered Tier 1 or Tier 2 exchanges. Many of them upfront will tell you there are no fees associated with the listing, that is not entirely true most of the time. Regardless, have applied and are awaiting more responses as we move forward. Listing on these exchanges often requires that we cannot announce this information until ColossusXT is live on its platform.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Partnerships are the norm these days in crypto world. Which partnership would you consider feasible, if any, in order to grow the Colossus Grid project?
A: The Colossus Grid is a huge undertaking both in development and business partnerships. We are moving in both these directions strategically. One of the most important partnerships is not really a partnership but approval to bid on state and federal contracts. Working with the governments around the world will be a big part of the Colossus Grid use-case.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: If the ability to annonymise coins is turned off, can CLX still be marketed as a privacy coin? Do we have a date we can start using this feature again?
A: Yes and No. It’s frustrating right now having a lack of privacy for consumers as we don’t see privacy as a feature but a right. EVERY platform online should have some levels of privacy for their consumers, especially as technology continues to evolve and bad actors continue to use your personal information for their own nefarious purposes. Obfuscation will be implemented in the coming weeks, and Armis will follow suit shortly thereafter.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: When can we expect the grid to come out?
A: We are looking at releasing an MVP towards the end of the year. Stay tuned during Q3 and Q4 as we ramp on technical and business developments.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Can you tell the current budget for development work?
A: Much of the development work budget comes from Core team member's disposable income, we also use the self-funding treasury that Masternode owners vote on each month.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Will cold staking be implemented somedays? I like the model of Cardano. Hope you will implement kind of Cardano staking in our wallet. I would love the easiness.
A: ColossusXT staking has been enabled since 2017. We have calculators on the website that will estimate your average staking returns and you can join numerous pools to increase your staking power within the pools. Cold staking is on our radar and will make it into the roadmap when our budget allows us.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Which part of grid technology are you planning first to go live? Storage/RAM/CPU/GPU/all at once? Separately?
A: We will be rolling the Colossus Grid out in two phases. The first phase will be storage, and then we will roll out computing power (RAM/CPU/GPU).
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Is Armis I2P technology in development testphase I mean, I have read something like that… If Armis goes live, will there be some kind of option in deskopt wallet to transfer anonymous or will every transaction be fully anonymous like e.g. monero?
A: We recently had a testing phase with the community earlier this year, there will be another test phase with community participants who sign up. If you’re interested in this stay tuned on our socials and apply when the next testing phase happens All transactions will be fully anonymous behind Armis.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: What programming languate is being used for developing COLX? How well this programming language do you think is more suitable for developing crypto, in comparison with other programing languages?
A: C++ is what we’re using at ColossusXT. Each crypto project is different but with what we're developing at ColossusXT. We are best suited to utilize C++.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: What is the second biggest milestone other than launching the grid network for the team. What do you think of your competition like Golem network?
A: Armis will be a big milestone, and I don’t think we go back to our Polis partnership which allows users in Europe and Mexico (they do plan to expand to the US and other countries) the ability to spend their ColossusXT (COLX) wherever Mastercard is accepted. I don’t think the Golem network is taking consumer privacy far enough, in the blockchain industry I also see a lack of drive to push adoption within the United States. This is likely due to unclear regulations right now. ColossusXT is at the forefront of these issues and we intend to lead blockchain through these somewhat murky waters.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: I don’t have a lot of knowledge about crypto-technology… but are there any risks of sensitive data-hijacks through Colx infrastructure? Will the Colx-grid be available for individuals or only larger corporations, and how would one get access to the computing power?
A: There are always risks with technology. We are doing extensive testing and more testing prior to releasing anything. Consumer privacy is apart of the foundation of what we’re building at ColossusXT and we want to ensure any and all of your personal information is secure and private. As technology evolves, we will be right here evolving with it to ensure that consumer privacy protections are always in place.
The Colossus Grid will be available to anyone with a computer. You will access it through the desktop wallet.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Do you have any new exchange listings planned in the near future?
A: Yes, but unfortunately with these things, every day it’s not something we can often say before the exchange makes their own announcements. If you have certain exchanges that you prefer, do not be shy and tag us on Twitter letting us and the exchange know. You can also reach us everyday at all hours of the day and night on Discord and Telegram.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Given that Colx had no ICO, are we able to ramp development efforts in case we have potential partnership deal on the table?
A: It really depends. We strategically spend every dime we spend on development. We do not like even a single penny to be waisted, so we don’t move as fast as the projects that raised millions of dollars, but we continue moving none the less. Ramping up our development is something we are working on by securing additional funding and we’re currently working on securing funding. 😊
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How is the project development advancing? What are your plans for the next 5 years and what more can we expect from ColossusXT?
A: Our development is continuing on at a steady pace, we’re looking to ramp this up over the next year as the Colossus Grid will take much of our time but we’re excited. Over the next 5 years, you can expect the Colossus Grid to be live in all forms (storage and computing power), Armis will be released and we will share many technical details on how this consumer privacy protection rivals some of the other privacy protections in the blockchain industry. We expect to be verified and approved to work with the agencies in the United States long before then as well and will be aggressively pursuing federal contracts to utilize the computing power of the Colossus Grid. In 5 years, we plan to be a key player not just in the blockchain industry, but throughout the world. If you do not know ColossusXT now, expect to in 5 years or less.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Users often care less about technology, but rather the value of the token. How do you manage to strike a balance between developing the technology and also improving the value of COLX? There are so many privacy coins now, all of them claiming to have better features that ColossusXT. Moving forward, what do the next 10 years look like for ColossusXT in navigating the wave of privacy projects coming. How can ColossusXT continue to shine in the midst of seemingly legit projects that have come to challenge ColossusXT like mimblewimble projects and Monero, Zcoin, ect.?

A: The Colossus Grid and Masternodes will have a strong relationship with each other. When the Colossus Grid goes live we expect the masternode demand to continue to rise. Masternodes are a great incentive mechanism to increase network strength and will play an important role within the Colossus Grid. The more masternodes online, the less available coins in the circulating supply; which we expect will eventually reflect ColossusXT (COLX) coin value.
Over the next 10 years, ColossusXT (COLX) will solidify itself as a key player in the blockchain industry, and outside the blockchain industry. Following our strategic business plans, we intend to be one of the first, if not the first to truly bring government and other businesses into the blockchain industry through the Colossus Grid. Armis will be our defining privacy feature, which we expect in time will begin to be adopted by other projects. --------------------------------------------------------------------------------------------------------------------------------------------------
Q: How have the number of Masternodes (MNs) increased/decreased over time/in the past few years? What proportion (%) of MNs actively take part in Governance? How do you see the number of MNs increasing/decreasing in the next couple of years? Is there a trend upwards or downwards?
Is there a specific number (or range) of MNs the team would like to attain ideally? Is it better to have as many MNs as possible or is there a point at which too many MNs start to have an adverse effect on the performance of the blockchain?
Hope this wasn’t too many questions in one :), Ahmed

A: The number of masternodes in the active network is more or less the same, fluctuating around 200-220. About 40% - 50% of masternodes participate actively in governance (see https://governance.colossusxt.io). We expect a number of masternodes to grow as they will have additional benefits with Colossus Grid (see business plan: http://bit.ly/COLXBPLive).
As the team had no premines, only the dev fund can be used for masternodes which is hard to maintain due to actual budget flow. It’s better to have as many masternodes as possible for the network, there is no adverse effect.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Of all the milestones that $COLX has achieved since your humble beginnings, which do you consider to be the best of it all? What achievements do you feel proud most?
A: It’s often not mentioned but I’m very proud of our partnership with PolisPay, which allows ColossusXT community members to purchase Amazon, Spotify, and other gift cards with ColossusXT (COLX) through the Polis platform. You are also able to spend your COLX anywhere Mastercard is accepted, the card is available only for EU citizens right now and the Polis team hopes to bring in other countries in the future.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: There are problems that can slow down the course of a project such as the emergence of globalization, given the tighter budget, shorter implementation time requirements. My question is, How does $COLX resolve the issue?

A: Given the current situations around the world the Colossus Grid has more value than it ever has, and that value will continue to grow once we have released the Colossus Grid for consumers to share and utilize resources. You can already see from the [email protected] initiative that people are eager to share their computing resources to help researchers simulate different COVID19 simulations. We’ve always worked on a very small budget at ColossusXT starting with 0$ in funding and no pre-mine or ICO/IEO. This project was built for the community by the community, and as of lately we’ve actually been ramping up our business strategies and developments. Since we have all already worked remotely before the COVID19 pandemic, it interestingly allowed us more time to focus and achieve these goals as our day jobs allowed us to spend more time on ColossusXT.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How will you fight with regulators who are trying to stop privacy coins?

A: We have an amazing legal team at ColossusXT, and they are on top of any new law or regulation that comes out. We’re not afraid of regulators and our legal team makes sure that everything we do for ColossusXT is law-abiding. It's time the world stops looking at privacy as a feature and as a right, especially when you read about different applications and platforms using your personal DATA for their benefit. ColossusXT will continue to push this, and we're prepared to lobby this to lawmakers. --------------------------------------------------------------------------------------------------------------------------------------------------
Q: What type of utilities can $COLX give to users over its competitors like GOLM (computation) or STORJ (Data)?

A: The Colossus Grid has some major differences between Golem and Storj. One we’re a privacy-focused project. If you take a look at many of these applications and platforms today, in some way or another you’re giving up personal information, and/or geographic information. ColossusXT is focused on protecting consumer information, we do not look at privacy as a feature, we see privacy as a right, especially in the tech world today.
The second part of this question is that we’re currently in the verification process of registering with the United States federal and state governments so that we can legally bid on federal and state projects and work with different agencies. This will ensure that as the community members are sharing their idle resources, large corporations and businesses are using it. I’m not aware of the mentioned projects being registered in the United States or taking steps to work with the United States government.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How will computing power and storage sharing look like, for an average user (marketplace, program download)? What are you currently working on, when can we expect MVP? TY
A: The marketplace and Colossus Grid will be inside the ColossusXT desktop wallet that you currently have now. The UI/UX will change some to allow the additional settings and tabs that will become available and we’re preparing an MVP right now and we hope to share those details with you over the next few months, ask us again in the Q3 AMA if you haven’t seen anything yet :)
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: What would you say is the $COLX killer feature that sets it apart from the rest of the competition.
A: We believe that Armis is our killer feature. We recently had a beta this year with the community and will be moving forward later this year with Armis. ColossusXT consumers will have their geographic location and IP fully hidden behind the Armis layer for further security and anonymity for the transactions which will also take place in the Colossus Grid resource marketplace in the future.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: I have been a silent follower of $COLX and I must say that I'm truly impressed with how the team has been diligently working on the project. It'd be nice to have the community be part of something like a bounty or a social awareness contest. As this will not only attract more users to the platform but would also strengthen the bond within the community. When can we possibly expect a community project of this level? #spreadthegrid
A: We currently have a Gleam competition ongoing for social awareness, and we just hired a community manager to spread more community awareness and will be rolling on competitions more regularly. Every quarter we have an AMA on Reddit for the community to ask questions, or just gripe at us, and one person each quarter is awarded 100,000 COLX for participating in the AMA. As we deliver our targets and grow, we will shift more funds from development funds to marketing funds to raise further awareness.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: "Our main competitor is crypto adoption. We are all here to make it happen together.", this is quoted from a founder of a known crypto wallet. Do you see competition as something that strengthens the project as a whole or as a possible distraction due to pressure to be at the top of the crypto ecosystem?

A: This is a two scenario situation. Competition is good for ColossusXT, and we look at our main competitor in blockchain as Golem (GNT), having said that though too much competition or sometimes maximalist behavior isn’t good for crypto, many of these projects should be coming together to lobby lawmakers for laws and regulations that are good for the blockchain industry, as this is still an emerging market and the laws and regulations aren’t exactly in place at this time.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: "For people to believe in crypto, they need to understand the tangible benefits it offers to our society.", a remark made by a crypto project in the past. What exactly would be $COLX real life global benefits? And how do you plan on achieving this?
A: ColossusXT vision will be achievable when the Colossus Grid is released. We are currently in the process of registering with state and federal agencies in the United States, once we are registered to work with these agencies we will pursue contracts with the government, cybersecurity firms and colleges all around the United States, and the world to utilize the resources on the Colossus Grid. We’ve already started building business relationships for this very purpose.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: According to you how much time will it take for $COLX to get into mainstream adoption and execute all the plans set for this project?
A: It’s almost impossible to set a timeline on when the world/people will begin to adopt ColossusXT (COLX) and the Colossus Grid. We don’t believe that adoption for ColossusXT will happen before the Colossus Grid is live, and if I gave you an exact timeline for when or how long it will take you for the Colossus Grid to be adopted I would be lying to you, but we are already forming business relationships and making strategic moves to be able to bid, and work with state and federal agencies in the United States.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Does Tokens.net plan any kind of staking ($COLX or other coins)?
A: We will reach out to the tokens.net team and see if they have any plans to allow staking.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How will you try to boost adoption of #COLX, how do you think you will motivate programmers to join opensource project?
A: The Colossus Grid will be available for anyone to use, or share their idle resources for other consumers to use. We will be focusing on providing these resources to state and federal governments, cybersecurity firms, and researchers all across the world. Certainly, we expect some community members to use these resources to mine different PoW cryptocurrencies, but the team at ColossusXT will be focused on bringing in large colleges and universities as well as big cybersecurity businesses that may need supercomputing power at 1/10th of the current prices. Our programmers are our only paid team members, and we pay them at a competitive rate. We’re looking to bring in some more programmers later this year.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Do you have any special development funds for programmers?
A: Sometimes we pay our programmers out of our own pocket, sometimes we pay them in ColossusXT. It really depends on what kind of agreements have been made. We have been aggressively pursuing different funding opportunities throughout 2020 so that we can expand our development team and in the future, we may have incentives to drive programmers into joining our team. Right now we just stick to a competitive pay scale within the industry.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Why Android Wallet Revision hasn't been done? Any problems?
A: The Android wallet revision took some time to be approved in the Google Playstore, but it has been released and live since June 15, 2020.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Whats the second biggest milestone other than the grid network for COLX team?
A: Armis is likely to be considered our second biggest milestone this year, although as I mentioned above this can easily be overshadowed by our Polis partnership which allows you to spend ColossusXT (COLX) anywhere Mastercard is accepted. Although the epay debit card ownership is currently restricted to certain countries (EU zone only), these restrictions will lift in time.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How is COLX team going to contribute to crypto adoption, other than building a robust network?
A: We’re already in the process of verification to work with state and federal agencies. Adoption for blockchain projects isn’t going to move fast. I read a report just a few days ago about how scammers in the crypto industry stole over 2 million dollars worth of crypto just from the “Elon Musk” impersonations on Twitter.
We will continue to build our network, and seek out state and federal agencies as well as private cybersecurity firms that can utilize the Colossus Grid, we’re not just focused on making noise on social media, we intend to make noise throughout the entire world.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Are their industry partners to COLX that are awaiting your network to go live?
A: Yes, although I hesitate to go into too much detail here. We are talking with business leaders.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: The ongoing crisis affected the market badly, making many projects far from their targets. What is $COLX strategy in order to survive and pass through this crisis?
A: I agree it affected the market badly, especially the projects that raised hundreds of millions of dollars in crypto and held it through the entire market correction. ColossusXT strategy is different from those affected, we’ve always had a smaller budget than these large projects. We spend the money we have available very wisely, and we’re not in a hurry to grab something that sounds good without doing our due diligence. We make our moves very strategically.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: I gotta ask, what made $COLX decide to get listed on Tokens.net? What beneficial advantage does $COLX get in doing so? How about Tokens.net?
A: Tokens.Net is one of the best exchanges ColossusXT is listed at the moment in comparison to others in terms of volume.
  1. Tokens.net is one of the most secure and transparent exchanges out there, registered in the UK.
  2. The team behind the exchange has deep roots in the crypto/blockchain space, it was co-founded by Damian Merlak, a crypto-pioneer and co-founder of Bitstamp.
  3. Tokens.net provides free auto-trading tool / Market Making Bot. Their Dynamic Trading Rights concept adds transparency to trading volumes.
  4. They allow the community voting option of only truly decentralized projects after a thorough screening.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Hey everyone! What is the main purpose of the coin $COLX, does it have its own chain or is it some sort of an ERC-20 token? Thank you for the answers.
A: ColossusXT has never been an ERC-20 coin. We have been operating on our own mainnet since 2017. The purpose of ColossusXT (COLX) is to be the native currency of the Colossus Grid. This will allow users to share their idle resources on their computers, and consumers will rent/buy those resources to complete whatever they intend to use them for, from processing large DATA to running scientific simulations, to even mining PoW cryptocurrencies.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: When we can expect any usecase for COLX? A company or service that uses colx for its activities / tasks.
A: There are currently use cases now if your location allows you to utilize the Polis Pay app, or if you have a Polis Pay card you can buy things with ColossusXT (COLX). I myself have tested the card buying gas at a gas station. These are not ColossusXT’s primary focus though and much of our use case will not start until the Colossus Grid is live.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: What pairs will colx have to trade with on tokens.net // Will you connect #COLX with USDT EURS or BTC?
A: ColossusXT will be initially paired with Bitcoin (BTC). If the community would like different pairs, they can certainly request them and we will reach out to tokens.net and work to facilitate requests.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Will you try to convince users to trade on tokens.net if so how will you do it?
A: There is currently a gleam competition for users to sign up and trade on tokens.net. We “shill” tokens.net accordingly through social media to the ColossusXT community, but can’t really convince anyone to use a certain exchange, although we will try to push as many members to tokens.net as we can. We have many masternode holders who reside in the United States and they are not yet allowed to trade on tokens.net.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How will you try to create liquidity for your pairs?
A: We would like to increase the adoption rate with real-world partnerships such as our partnership with PolisPay for the use of gift/debit cards. As the liquidity is linked with the use cases, supply/demand mechanics, we are also preparing to provide additional use cases of COLX for the crypto world in an innovative & pioneering way; for the time being, we can hint this as a side business till we deliver fully operational Colossus Grid.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How big is a development team of #COLX?
A: The ColossusXT team is probably bigger than some people realize, partly because many of the team members are very private. We have 9 core members, 2 in-house developers, 3 Colossus Grid architects, and 2 Colossus Grid developers.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Do you have some security guys in the team?
A: Yes, although I’m hesitant to share too many personal details about team members. We have core team members who have been working in different fields of IT security for several years.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Since #COLX is planning on having some sort of a marketplace where you can take advantage of computing resources and the blockchain as well, are there any plans on introducing smart contracts? Will it help the grid? Is there a place for it?
A: This has been mentioned a few times in the past so it’s something on our radar, it’s currently not in the development timeline as the Colossus Grid is a massive amount of work. There may be a place for it as the blockchain industry evolves, and I can certainly see some cases where a smart contract can add some value to the Colossus Grid.

New Qubes OS Room on Matrix!

New Qubes OS Room on matrix!
 
This is just to let potentially interested people know that there is now a new Qubes OS room on matrix which is part of the +cybersec:matrix.org community. The rules for this group are simple, have a (qubes-ish) question, ask a (qubes-ish) question or take it to #cybersec-offtopic. In general the main rule is don't be a D*ck (not duck in case you were wondering, ducks are fine).
 
Some reasons/examples of why Qubes might be of interest:
 
And many more reasons. The room welcomes all, if you are a noob come ask a question, if you are a guru (not even necessarily with Qubes but maybe distro or application specific) please come and help add to the knowledge base! One of the main goals here is to have flexible and civil support/discussions related to Qubes.
 
Hope to see you all there!
PS Apologies to the mods if you do not consider this appropriate, I reviewed the rules and think its ok? My reasons for cross posting is that I think Qubes has a very real use case for this subreddit so I thought it would be useful for users in these subreddits and hopefully helpful for Qubes users as well.

Cryptocurrency regulations of the future

Will China/USA/Europe ban the use of Bitcoin and traditional cryptocurrencies (including privacy coins) after they introduce their own state-controlled Central Bank Digital Currencies? Will they use fear, fake news of crime to justify this? They want to control money, they want data.
Will they first cripple these currencies by regulating the shit out of them, assigning different value to coins people they don't like owed at some point? Regulations already started, everyone owning crypto is deanonymized, exchange is heavily controlled, centralized exchanges steal money from people they don't like by "freezing" their accounts.
If big cuntries ban real cryptocurrencies, when 25%/50%/75% of all users loose access, how will that fuck with the price?
Will people use decentralized networks -- like Tor and I2P -- to have access to crypto? China already bans Tor, and makes it almost impossible to access the network. Hardware and software spies on all of us. China banned the real internet, now Russia wants to follow. Australia tries to ban cryptography, now USA wants to follow, again. What will we do when other cuntries start banning privacy networks?
Support decentralization, support free software. Don't let propaganda influence you, don't accept regulations.

Your Guide to Monero, and Why It Has Great Potential

/////Your Guide to Monero, and Why It Has Great Potential/////

Marketing.
It's a dirty word for most members of the Monero community.
It is also one of the most divisive words in the Monero community. Yet, the lack of marketing is one of the most frustrating things for many newcomers.
This is what makes this an unusual post from a member of the Monero community.
This post is an unabashed and unsolicited analyzation of why I believe Monero to have great potential.
Below I have attempted to outline different reasons why Monero has great potential, beginning with upcoming developments and use cases, to broader economic motives, speculation, and key issues for it to overcome.
I encourage you to discuss and criticise my musings, commenting below if you feel necessary to do so.

///Upcoming Developments///

Bulletproofs - A Reduction in Transaction Sizes and Fees
Since the introduction of Ring Confidential Transactions (Ring CT), transaction amounts have been hidden in Monero, albeit at the cost of increased transaction fees and sizes. In order to mitigate this issue, Bulletproofs will soon be added to reduce both fees and transaction size by 80% to 90%. This is great news for those transacting smaller USD amounts as people commonly complained Monero's fees were too high! Not any longer though! More information can be found here. Bulletproofs are already working on the Monero testnet, and developers were aiming to introduce them in March 2018, however it could be delayed in order to ensure everything is tried and tested.
Multisig
Multisig has recently been merged! Mulitsig, also called multisignature, is the requirement for a transaction to have two or more signatures before it can be executed. Multisig transactions and addresses are indistinguishable from normal transactions and addresses in Monero, and provide more security than single-signature transactions. It is believed this will lead to additional marketplaces and exchanges to supporting Monero.
Kovri
Kovri is an implementation of the Invisible Internet Project (I2P) network. Kovri uses both garlic encryption and garlic routing to create a private, protected overlay-network across the internet. This overlay-network provides users with the ability to effectively hide their geographical location and internet IP address. The good news is Kovri is under heavy development and will be available soon. Unlike other coins' false privacy claims, Kovri is a game changer as it will further elevate Monero as the king of privacy.
Mobile Wallets
There is already a working Android Wallet called Monerujo available in the Google Play Store. X Wallet is an IOS mobile wallet. One of the X Wallet developers recently announced they are very, very close to being listed in the Apple App Store, however are having some issues with getting it approved. The official Monero IOS and Android wallets, along with the MyMonero IOS and Android wallets, are also almost ready to be released, and can be expected very soon.
Hardware Wallets
Hardware wallets are currently being developed and nearing completion. Because Monero is based on the CryptoNote protocol, it means it requires unique development in order to allow hardware wallet integration. The Ledger Nano S will be adding Monero support by the end of Q1 2018. There is a recent update here too. Even better, for the first time ever in cryptocurrency history, the Monero community banded together to fund the development of an exclusive Monero Hardware Wallet, and will be available in Q2 2018, costing only about $20! In addition, the CEO of Trezor has offered a 10BTC bounty to whoever can provide the software to allow Monero integration. Someone can be seen to already be working on that here.
TAILS Operating System Integration
Monero is in the progress of being packaged in order for it to be integrated into TAILS and ready to use upon install. TAILS is the operating system popularised by Edward Snowden and is commonly used by those requiring privacy such as journalists wanting to protect themselves and sources, human-right defenders organizing in repressive contexts, citizens facing national emergencies, domestic violence survivors escaping from their abusers, and consequently, darknet market users.
In the meantime, for those users who wish to use TAILS with Monero, u/Electric_sheep01 has provided Sheep's Noob guide to Monero GUI in Tails 3.2, which is a step-by-step guide with screenshots explaining how to setup Monero in TAILS, and is very easy to follow.
Mandatory Hardforks
Unlike other coins, Monero receives a protocol upgrade every 6 months in March and September. Think of it as a Consensus Protocol Update. Monero's hard forks ensure quality development takes place, while preventing political or ideological issues from hindering progress. When a hardfork occurs, you simply download and use the new daemon version, and your existing wallet files and copy of the blockchain remain compatible. This reddit post provides more information.
Dynamic fees
Many cryptocurrencies have an arbitrary block size limit. Although Monero has a limit, it is adaptive based on the past 100 blocks. Similarly, fees change based on transaction volume. As more transactions are processed on the Monero network, the block size limit slowly increases and the fees slowly decrease. The opposite effect also holds true. This means that the more transactions that take place, the cheaper the fees!
Tail Emission and Inflation
There will be around 18.4 million Monero mined at the end of May 2022. However, tail emission will kick in after that which is 0.6 XMR, so it has no fixed limit. Gundamlancer explains that Monero's "main emission curve will issue about 18.4 million coins to be mined in approximately 8 years. (more precisely 18.132 Million coins by ca. end of May 2022) After that, a constant "tail emission" of 0.6 XMR per 2-minutes block (modified from initially equivalent 0.3 XMR per 1-minute block) will create a sub-1% perpetual inflatio starting with 0.87% yearly inflation around May 2022) to prevent the lack of incentives for miners once a currency is not mineable anymore.
Monero Research Lab
Monero has a group of anonymous/pseudo-anonymous university academics actively researching, developing, and publishing academic papers in order to improve Monero. See here and here. The Monero Research Lab are acquainted with other members of cryptocurrency academic community to ensure when new research or technology is uncovered, it can be reviewed and decided upon whether it would be beneficial to Monero. This ensures Monero will always remain a leading cryptocurrency. A recent end of 2017 update from a MRL researcher can be found here.

///Monero's Technology - Rising Above The Rest///

Monero Has Already Proven Itself To Be Private, Secure, Untraceable, and Trustless
Monero is the only private, untraceable, trustless, secure and fungible cryptocurrency. Bitcoin and other cryptocurrencies are TRACEABLE through the use of blockchain analytics, and has lead to the prosecution of numerous individuals, such as the alleged Alphabay administrator Alexandre Cazes. In the Forfeiture Complaint which detailed the asset seizure of Alexandre Cazes, the anonymity capabilities of Monero were self-demonstrated by the following statement of the officials after the AlphaBay shutdown: "In total, from CAZES' wallets and computer agents took control of approximately $8,800,000 in Bitcoin, Ethereum, Monero and Zcash, broken down as follows: 1,605.0503851 Bitcoin, 8,309.271639 Ethereum, 3,691.98 Zcash, and an unknown amount of Monero".
Privacy CANNOT BE OPTIONAL and must be at a PROTOCOL LEVEL. With Monero, privacy is mandatory, so that everyone gets the benefits of privacy without any transactions standing out as suspicious. This is the reason Darknet Market places are moving to Monero, and will never use Verge, Zcash, Dash, Pivx, Sumo, Spectre, Hush or any other coins that lack good privacy. Peter Todd (who was involved in the Zcash trusted setup ceremony) recently reiterated his concerns of optional privacy after Jeffrey Quesnelle published his recent paper stating 31.5% of Zcash transactions may be traceable, and that only ~1% of the transactions are pure privacy transactions (i.e., z -> z transactions). When the attempted private transactions stand out like a sore thumb there is no privacy, hence why privacy cannot be optional. In addition, in order for a cryptocurrency to truly be private, it must not be controlled by a centralised body, such as a company or organisation, because it opens it up to government control and restrictions. This is no joke, but Zcash is supported by DARPA and the Israeli government!.
Monero provides a stark contrast compared to other supposed privacy coins, in that Monero does not have a rich list! With all other coins, you can view wallet balances on the blockexplorers. You can view Monero's non-existent rich list here to see for yourself.
I will reiterate here that Monero is TRUSTLESS. You don't need to rely on anyone else to protect your privacy, or worry about others colluding to learn more about you. No one can censor your transaction or decide to intervene. Monero is immutable, unlike Zcash, in which the lead developer Zooko publicly tweeted the possibility of providing a backdoor for authorities to trace transactions. To Zcash's demise, Zooko famously tweeted:
" And by the way, I think we can successfully make Zcash too traceable for criminals like WannaCry, but still completely private & fungible. …"
Ethereum's track record of immutability is also poor. Ethereum was supposed to be an immutable blockchain ledger, however after the DAO hack this proved to not be the case. A 2016 article on Saintly Law summarised the problematic nature of Ethereum's leadership and blockchain intervention:
" Many ethereum and blockchain advocates believe that the intervention was the wrong move to make in this situation. Smart contracts are meant to be self-executing, immutable and free from disturbance by organisations and intermediaries. Yet the building block of all smart contracts, the code, is inherently imperfect. This means that the technology is vulnerable to the same malicious hackers that are targeting businesses and governments. It is also clear that the large scale intervention after the DAO hack could not and would not likely be taken in smaller transactions, as they greatly undermine the viability of the cryptocurrency and the technology."
Monero provides Fungibility and Privacy in a Cashless World
As outlined on GetMonero.org, fungibility is the property of a currency whereby two units can be substituted in place of one another. Fungibility means that two units of a currency can be mutually substituted and the substituted currency is equal to another unit of the same size. For example, two $10 bills can be exchanged and they are functionally identical to any other $10 bill in circulation (although $10 bills have unique ID numbers and are therefore not completely fungible). Gold is probably a closer example of true fungibility, where any 1 oz. of gold of the same grade is worth the same as another 1 oz. of gold. Monero is fungible due to the nature of the currency which provides no way to link transactions together nor trace the history of any particular XMR. 1 XMR is functionally identical to any other 1 XMR. Fungibility is an advantage Monero has over Bitcoin and almost every other cryptocurrency, due to the privacy inherent in the Monero blockchain and the permanently traceable nature of the Bitcoin blockchain. With Bitcoin, any BTC can be tracked by anyone back to its creation coinbase transaction. Therefore, if a coin has been used for an illegal purpose in the past, this history will be contained in the blockchain in perpetuity.
A great example of Bitcoin's lack of fungibility was reposted by u/ViolentlyPeaceful:
"Imagine you sell cupcakes and receive Bitcoin as payment. It turns out that someone who owned that Bitcoin before you was involved in criminal activity. Now you are worried that you have become a suspect in a criminal case, because the movement of funds to you is a matter of public record. You are also worried that certain Bitcoins that you thought you owned will be considered ‘tainted’ and that others will refuse to accept them as payment."
This lack of fungibility means that certain businesses will be obligated to avoid accepting BTC that have been previously used for purposes which are illegal, or simply run afoul of their Terms of Service. Currently some large Bitcoin companies are blocking, suspending, or closing accounts that have received Bitcoin used in online gambling or other purposes deemed unsavory by said companies. Monero has been built specifically to address the problem of traceability and non-fungibility inherent in other cryptocurrencies. By having completely private transactions Monero is truly fungible and there can be no blacklisting of certain XMR, while at the same time providing all the benefits of a secure, decentralized, permanent blockchain.
The world is moving cashless. Fact. The ramifications of this are enormous as we move into a cashless world in which transactions will be tracked and there is a potential for data to be used by third parties for adverse purposes. While most new cryptocurrency investors speculate upon vaporware ICO tokens in the hope of generating wealth, Monero provides salvation for those in which financial privacy is paramount. Too often people equate Monero's features with criminal endeavors. Privacy is not a crime, and is necessary for good money. Transparency in Monero is possible OFF-CHAIN, which offers greater transparency and flexibility. For example, a Monero user may share their Private View Key with their accountant for tax purposes.
Monero aims to be adopted by more than just those with nefarious use cases. For example, if you lived in an oppressive religious regime and wanted to buy a certain item, using Monero would allow you to exchange value privately and across borders if needed. Another example is that if everybody can see how much cryptocurrency you have in your wallet, then a certain service might decide to charge you more, and bad actors could even use knowledge of your wallet balance to target you for extortion purposes. For example, a Russian cryptocurrency blogger was recently beaten and robbed of $425k. This is why FUNGIBILITY IS ESSENTIAL. To summarise this in a nutshell:
"A lack of fungibility means that when sending or receiving funds, if the other person personally knows you during a transaction, or can get any sort of information on you, or if you provide a residential address for shipping etc. – you could quite potentially have them use this against you for personal gain"
For those that wish to seek more information about why Monero is a superior form of money, read The Merits of Monero: Why Monero Vs Bitcoin over on the Monero.how website.
Monero's Humble Origins
Something that still rings true today despite the great influx of money into cryptocurrencies was outlined in Nick Tomaino's early 2016 opinion piece. The author claimed that "one of the most interesting aspects of Monero is that the project has gained traction without a crowd sale pre-launch, without VC funding and any company or well-known investors and without a pre-mine. Like Bitcoin in the early days, Monero has been a purely grassroots movement that was bootstrapped by the creator and adopted organically without any institutional buy-in. The creator and most of the core developers serve the community pseudonymously and the project was launched on a message board (similar to the way Bitcoin was launched on an email newsletter)."
The Organic Growth of the Monero Community
The Monero community over at monero is exponentially growing. You can view the Monero reddit metrics here and see that the Monero subreddit currently gains more than 10,000 (yes, ten thousand!) new subscribers every 10 days! Compare this to most of the other coins out there, and it proves to be one of the only projects with real organic growth. In addition to this, the community subreddits are specifically divided to ensure the main subreddit remains unbiased, tech focused, with no shilling or hype. All trading talk is designated to xmrtrader, and all memes at moonero.
Forum Funding System
While most contributors have gratefully volunteered their time to the project, Monero also has a Forum Funding System in which money is donated by community members to ensure it attracts and retains the brightest minds and most skilled developers. Unlike ICOs and other cryptocurrencies, Monero never had a premine, and does not have a developer tax. If ANYONE requires funding for a Monero related project, then they can simply request funding from the community, and if the community sees it as beneficial, they will donate. Types of projects range from Monero funding for local meet ups, to paying developers for their work.
Monero For Goods, Services, and Market Places
There is a growing number of online goods and services that you can now pay for with Monero. Globee is a service that allows online merchants to accept payments through credit cards and a host of cryptocurrencies, while being settled in Bitcoin, Monero or fiat currency. Merchants can reach a wider variety of customers, while not needing to invest in additional hardware to run cryptocurrency wallets or accept the current instability of the cryptocurrency market. Globee uses all of the open source API's that BitPay does making integrations much easier!
Project Coral Reef is a service which allows you to shop and pay for popular music band products and services using Monero.
Linux, Veracrypt, and a whole array of VPNs now accept Monero.
There is a new Monero only marketplace called Annularis currently being developed which has been created for those who value financial privacy and economic freedom, and there are rumours Open Bazaar is likely to support Monero once Multisig is implemented.
In addition, Monero is also supported by The Living Room of Satoshi so you can pay bills or credit cards directly using Monero.
Monero can be found on a growing number of cryptocurrency exchange services such as Bittrex, Poloniex, Cryptopia, Shapeshift, Changelly, Bitfinex, Kraken, Bisq, Tux, and many others.
For those wishing to purchase Monero anonymously, there are services such as LocalMonero.co and Moneroforcash.com.
With XMR.TO you can pay Bitcoin addresses directly with Monero. There are no other fees than the miner ones. All user records are purged after 48 hours. XMR.TO has also been added as an embedded feature into the Monerujo android wallet.
Coinhive Browser-Based Mining
Unlike Bitcoin, Monero can be mined using CPUs and GPUs. Not only does this encourage decentralisation, it also opens the door to browser based mining. Enter side of stage, Coinhive browser-based mining. As described by Hon Lau on the Symnatec Blog Browser-based mining, as its name suggests, is a method of cryptocurrency mining that happens inside a browser and is implemented using Javascript. Coinhive is marketed as an alternative to browser ad revenue. The motivation behind this is simple: users pay for the content indirectly by coin mining when they visit the site and website owners don't have to bother users with sites laden with ads, trackers, and all the associated paraphern. This is great, provided that the websites are transparent with site visitors and notify users of the mining that will be taking place, or better still, offer users a way to opt in, although this hasn't always been the case thus far.
Skepticism Sunday
The main Monero subreddit has weekly Skepticism Sundays which was created with the purpose of installing "a culture of being scientific, skeptical, and rational". This is used to have open, critical discussions about monero as a technology, it's economics, and so on.

///Speculation///

Major Investors And Crypto Figureheads Are Interested
Ari Paul is the co-founder and CIO of BlockTower Capital. He was previously a portfolio manager for the University of Chicago's $8 billion endowment, and a derivatives market maker and proprietary trader for Susquehanna International Group. Paul was interviewed on CNBC on the 26th of December and when asked what was his favourite coin was, he stated "One that has real fundamental value besides from Bitcoin is Monero" and said it has "very strong engineering". In addition, when he was asked if that was the one used by criminals, he replied "Everything is used by criminals including the US dollar and the Euro". Paul later supported these claims on Twitter, recommending only Bitcoin and Monero as long-term investments.
There are reports that "Roger Ver, earlier known as 'Bitcoin Jesus' for his evangelical support of the Bitcoin during its early years, said his investment in Monero is 'substantial' and his biggest in any virtual currency since Bitcoin.
Charlie Lee, the creator of Litecoin, has publicly stated his appreciation of Monero. In a September 2017 tweet directed to Edward Snowden explaining why Monero is superior to Zcash, Charlie Lee tweeted:
All private transactions, More tested privacy tech, No tax on miners to pay investors, No high inflation... better investment.
John McAfee, arguably cryptocurrency's most controversial character at the moment, has publicly supported Monero numerous times over the last twelve months(before he started shilling ICOs), and has even claimed it will overtake Bitcoin.
Playboy instagram celebrity Dan Bilzerian is a Monero investor, with 15% of his portfolio made up of Monero.
Finally, while he may not be considered a major investor or figurehead, Erik Finman, a young early Bitcoin investor and multimillionaire, recently appeared in a CNBC Crypto video interview, explaining why he isn't entirely sold on Bitcoin anymore, and expresses his interest in Monero, stating:
"Monero is a really good one. Monero is an incredible currency, it's completely private."
There is a common belief that most of the money in cryptocurrency is still chasing the quick pump and dumps, however as the market matures, more money will flow into legitimate projects such as Monero. Monero's organic growth in price is evidence smart money is aware of Monero and gradually filtering in.
The Bitcoin Flaw
A relatively unknown blogger named CryptoIzzy posted three poignant pieces regarding Monero and its place in the world. The Bitcoin Flaw: Monero Rising provides an intellectual comparison of Monero to other cryptocurrencies, and Valuing Cryptocurrencies: An Approach outlines methods of valuing different coins.
CryptoIzzy's most recent blog published only yesterday titled Monero Valuation - Update and Refocus is a highly recommended read. It touches on why Monero is much more than just a coin for the Darknet Markets, and provides a calculated future price of Monero.
CryptoIzzy also published The Power of Money: A Case for Bitcoin, which is an exploration of our monetary system, and the impact decentralised cryptocurrencies such as Bitcoin and Monero will have on the world. In the epilogue the author also provides a positive and detailed future valuation based on empirical evidence. CryptoIzzy predicts Monero to easily progress well into the four figure range.
Monero Has a Relatively Small Marketcap
Recently we have witnessed many newcomers to cryptocurrency neglecting to take into account coins' marketcap and circulating supply, blindly throwing money at coins under $5 with inflated marketcaps and large circulating supplies, and then believing it's possible for them to reach $100 because someone posted about it on Facebook or Reddit.
Compared to other cryptocurrencies, Monero still has a low marketcap, which means there is great potential for the price to multiply. At the time of writing, according to CoinMarketCap, Monero's marketcap is only a little over $5 billion, with a circulating supply of 15.6 million Monero, at a price of $322 per coin.
For this reason, I would argue that this is evidence Monero is grossly undervalued. Just a few billion dollars of new money invested in Monero can cause significant price increases. Monero's marketcap only needs to increase to ~$16 billion and the price will triple to over $1000. If Monero's marketcap simply reached ~$35 billion (just over half of Ripple's $55 billion marketcap), Monero's price will increase 600% to over $2000 per coin.
Another way of looking at this is Monero's marketcap only requires ~$30 billion of new investor money to see the price per Monero reach $2000, while for Ethereum to reach $2000, Ethereum's marketcap requires a whopping ~$100 billion of new investor money.
Technical Analysis
There are numerous Monero technical analysts, however none more eerily on point than the crowd-pleasing Ero23. Ero23's charts and analysis can be found on Trading View. Ero23 gained notoriety for his long-term Bitcoin bull chart published in February, which is still in play today. Head over to his Trading View page to see his chart: Monero's dwindling supply. $10k in 2019 scenario, in which Ero23 predicts Monero to reach $10,000 in 2019. There is also this chart which appears to be freakishly accurate and is tracking along perfectly today.
Coinbase Rumours
Over the past 12 months there have been ongoing rumours that Monero will be one of the next cryptocurrencies to be added to Coinbase. In January 2017, Monero Core team member Riccardo 'Fluffypony' Spagni presented a talk at Coinbase HQ. In addition, in November 2017 GDAX announced the GDAX Digit Asset Framework outlining specific parameters cryptocurrencies must meet in order to be added to the exchange. There is speculation that when Monero has numerous mobile and hardware wallets available, and multisig is working, then it will be added. This would enable public accessibility to Monero to increase dramatically as Coinbase had in excess of 13 million users as of December, and is only going to grow as demand for cryptocurrencies increases. Many users argue that due to KYC/AML regulations, Coinbase will never be able to add Monero, however the Kraken exchange already operates in the US and has XMfiat pairs, so this is unlikely to be the reason Coinbase is yet to implement XMfiat trading.
Monero Is Not an ICO Scam
It is likely most of the ICOs which newcomers invest in, hoping to get rich quick, won't even be in the Top 100 cryptocurrencies next year. A large portion are most likely to be pumps and dumps, and we have already seen numerous instances of ICO exit scams. Once an ICO raises millions of dollars, the developers or CEO of the company have little incentive to bother rolling out their product or service when they can just cash out and leave. The majority of people who create a company to provide a service or product, do so in order to generate wealth. Unless these developers and CEOs are committed and believed in their product or service, it's likely that the funds raised during the ICO will far exceed any revenue generated from real world use cases.
Monero is a Working Currency, Today
Monero is a working currency, here today.
The majority of so called cryptocurrencies that exist today are not true currencies, and do not aim to be. They are a token of exchange. They are like a share in a start-up company hoping to use blockchain technology to succeed in business. A crypto-assest is a more accurate name for coins such as Ethereum, Neo, Cardano, Vechain, etc.
Monero isn't just a vaporware ICO token that promises to provide a blockchain service in the future. It is not a platform for apps. It is not a pump and dump coin.
Monero is the only coin with all the necessary properties to be called true money.
Monero is private internet money.
Some even describe Monero as an online Swiss Bank Account or Bitcoin 2.0, and it is here to continue on from Bitcoin's legacy.
Monero is alleviating the public from the grips of banks, and protests the monetary system forced upon us.
Monero only achieved this because it is the heart and soul, and blood, sweat, and tears of the contributors to this project. Monero supporters are passionate, and Monero has gotten to where it is today thanks to its contributors and users.

///Key Issues for Monero to Overcome///

Scalability
While Bulletproofs are soon to be implemented in order to improve Monero's transaction sizes and fees, scalability is an issue for Monero that is continuously being assessed by Monero's researchers and developers to find the most appropriate solution. Ricardo 'Fluffypony' Spagni recently appeared on CNBC's Crypto Trader, and when asked whether Monero is scalable as it stands today, Spagni stated that presently, Monero's on-chain scaling is horrible and transactions are larger than Bitcoin's (because of Monero's privacy features), so side-chain scaling may be more efficient. Spagni elaborated that the Monero team is, and will always be, looking for solutions to an array of different on-chain and off-chain scaling options, such as developing a Mimblewimble side-chain, exploring the possibility of Lightning Network so atomic swaps can be performed, and Tumblebit.
In a post on the Monero subreddit from roughly a month ago, monero moderator u/dEBRUYNE_1 supports Spagni's statements. dEBRUYNE_1 clarifies the issue of scalability:
"In Bitcoin, the main chain is constrained and fees are ludicrous. This results in users being pushed to second layer stuff (e.g. sidechains, lightning network). Users do not have optionality in Bitcoin. In Monero, the goal is to make the main-chain accessible to everyone by keeping fees reasonable. We want users to have optionality, i.e., let them choose whether they'd like to use the main chain or second layer stuff. We don't want to take that optionality away from them."
When the Spagni CNBC video was recently linked to the Monero subreddit, it was met with lengthy debate and discussion from both users and developers. u/ferretinjapan summarised the issue explaining:
"Monero has all the mechanisms it needs to find the balance between transaction load, and offsetting the costs of miner infrastructure/profits, while making sure the network is useful for users. But like the interviewer said, the question is directed at "right now", and Fluffys right to a certain extent, Monero's transactions are huge, and compromises in blockchain security will help facilitate less burdensome transactional activity in the future. But to compare Monero to Bitcoin's transaction sizes is somewhat silly as Bitcoin is nowhere near as useful as monero, and utility will facilitate infrastructure building that may eventually utterly dwarf Bitcoin. And to equate scaling based on a node being run on a desktop being the only option for what classifies as "scalable" is also an incredibly narrow interpretation of the network being able to scale, or not. Given the extremely narrow definition of scaling people love to (incorrectly) use, I consider that a pretty crap question to put to Fluffy in the first place, but... ¯_(ツ)_/¯"
u/xmrusher also contributed to the discussion, comparing Bitcoin to Monero using this analogous description:
"While John is much heavier than Henry, he's still able to run faster, because, unlike Henry, he didn't chop off his own legs just so the local wheelchair manufacturer can make money. While Morono has much larger transactions then Bitcoin, it still scales better, because, unlike Bitcoin, it hasn't limited itself to a cripplingly tiny blocksize just to allow Blockstream to make money."
Setting up a wallet can still be time consuming
It's time consuming and can be somewhat difficult for new cryptocurrency users to set up their own wallet using the GUI wallet or the Command Line Wallet. In order to strengthen and further decentralize the Monero network, users are encouraged to run a full node for their wallet, however this can be an issue because it can take up to 24-48 hours for some users depending on their hard-drive and internet speeds. To mitigate this issue, users can run a remote node, meaning they can remotely connect their wallet to another node in order to perform transactions, and in the meantime continue to sync the daemon so in the future they can then use their own node.
For users that do run into wallet setup issues, or any other problems for that matter, there is an extremely helpful troubleshooting thread on the Monero subreddit which can be found here. And not only that, unlike some other cryptocurrency subreddits, if you ask a question, there is always a friendly community member who will happily assist you. Monero.how is a fantastic resource too!
Despite still being difficult to use, the user-base and price may increase dramatically once it is easier to use. In addition, others believe that when hardware wallets are available more users will shift to Monero.

I actually still feel a little shameful for promoting Monero here, but feel a sense of duty to do so.
Monero is transitioning into an unstoppable altruistic beast. This year offers the implementation of many great developments, accompanied by the likelihood of a dramatic increase in price.
I request you discuss this post, point out any errors I have made, or any information I may have neglected to include. Also, if you believe in the Monero project, I encourage you to join your local Facebook or Reddit cryptocurrency group and spread the word of Monero. You could even link this post there to bring awareness to new cryptocurrency users and investors.
I will leave you with an old on-going joke within the Monero community - Don't buy Monero - unless you have a use case for it of course :-) Just think to yourself though - Do I have a use case for Monero in our unpredictable Huxleyan society? Hint: The answer is ?
Edit: Added in the Tail Emission section, and noted Dan Bilzerian as a Monero investor. Also added information regarding the XMR.TO payment service. Added info about hardfork
