Bitcoin Cash VS Litecoin: Which Cryptocurrency is Better ...

Reasons to be cheerful: Western Union removing 'WU vs. Bitcoin' Ad.

Earlier today, after being inspired by Daurgothoth I uploaded a Bitcoin Vs. Western Union Ad mocking WU's questionable use of grammar whilst comparing their prices to bitcoin. It ended up on top of /bitcoin and, multiple @westernunion tweets later, I was quite surprised to find my original upload has been mysteriously 'disappeared'.
I can only assume this was due to a complaint from WU that the ad infringes their trademark/copyright. Only problem being - it doesn't. The ad clearly falls under the rulings on Comparative Advertising.
So, as I imagine the furious WU PR department scrambling into damage limitation mode, resorting to spurious copyright takedowns as their only means to suppress from the public the embarrassing truth that bitcoin poses to their archaic business model... I can't help but reflect on how far we've come in the last year.
It is clear bitcoin is no longer at the 'first they laughed' stage and WU have moved into full on 'fight' mode - a year ago WU wouldn't have even blinked.
Yet, there's only so much fighting the truth you can do before you eventually self-destruct; especially when you're fighting an 'enemy' that is a decentralised movement of people with no board of directors, leaders, or obvious targets (beyond the odd redditor) to be bullied.
I guess it's bitcoiners that can do the laughing now.
EDIT: Some 4 hours or so after contacting imgur and requesting a copy of any applicable DMCA takedown notices, it appears the hard image link has just been reinstated (although the gallery/comment page is still down).

Digital Dollar, FedNow, CBDC, the central banks spending and global push for more control through digital currency.

At the beginning of the Covid-19 outbreak a few interesting things happened. China introduced the "Digital Yuan / RMB" And in April the "Digital dollar" was proposed in the first stimulus bill here in the USA. And they haven't stopped talking about it since. High tables from the White house Financial committee, Federal Reserve, US congress. Aiming to have a digital currency working as early as 2021 to provide UBI / Universal basic income to the masses, all while being able to track, freeze, limit, manipulate spending throughout the economy. Starting to sound rather like a "Black mirror film" isn't it? Well...China has taken it a step farther with their "Social Credit system" watching and controlling nearly every aspect of life. . . but we're here to talk about currency. How could this even happen in America? Well, to start
All of the above is a partial list of factors devaluing the Dollar and trust in it from several ways and views. At the end of the day it has a huge amount of enemies, that are all looking for ways to get out of it.
Some of what I'm seeing personally.
It is a death spiral for the working person, where it used to be "No more than 30% of your wage going to housing" It is now well over 50%....Just look at this recent post in Frugal https://www.reddit.com/Frugal/comments/ifqah1/is_it_normal_for_a_third_to_a_half_of_you?utm_source=share&utm_medium=web2x&context=3
This death spiral I foresee getting worse. And historically any "tax" / regulation cost will just be passed down to the consumer in form of increased prices until people / businesses move elsewhere as we've seen in several cities around the US.

So what can we do? Buy Gold! Silver! Bitcoin! Stocks! I hear people roar, They aren't exactly wrong as history shows... but have you considered the 30-40% tax on the "gain"? Even when that asset buys the same value before tax? What if the government makes it illegal like the 1933 order: 6102 Where you couldn't own gold for nearly 50 years? You're frozen out, or even out on taxes (which will likely be more strict and controlled later in time).
I'd say Invest in things that will
Metals are the next step when a person has plenty of the above. You get to a point where you have hundreds of thousands, if not millions that you need to condense into something real.
It is all about the savings or productivity gain of the investment. For instance I would wager that many preppers have gotten more use / value out of a $800 clothes washer than a $800 rifle. (have you ever had to do manual laundry???) Sure the rifle will hold value...but it often doesn't pay you back with time / what it saved and / or what it has produced during its life unless you are using it. Same can be said of security cameras, a generator, a tractor, trailer, garden, tools, ect.
Look at history even, in countries that have experienced hyperinflation people that already had tangibles they regularly use were way ahead. It could even be honey, a tool, extra maintenance parts, can of food, that bottle of medicine, a computer to keep your intel on point, (cough # PrepperIntel plug) use of your equipment to do or make something for someone. Real Estate is good too, it rides inflation well and has many ways of being productive.
Your metals could be sitting there like the rifle, and could be subject to hot debate and laws. Meanwhile that garden is paying back, chainsaw is helping saw up wood, or your tractor is helping a job, your tools just helped you fix something / saved you much loss, Your security stopped a loss not by a person, but an random animal stealing things. Or that $25,000 solar array is paying you back by the day in spades...while making you independent...running all your tools you're using to make things to sell, and even heating / cooling some of the house with the extra juice while places around you experience rolling blackouts. You were even smart and took the current 24% tax benefit the government has saving you $5000 on it for batteries. Don't get me started if you have an electric vehicle with solar... I'm rambling at this point...and all those stealthy / direct and passive background savings...even if the crap doesn't hit the fan.
So anyways, With out of control central banks and big governments, digital currencies, How do you think it will play out? Are we heading to dystopia?

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.

The attempted come back of CoinEx, China's forked-Bitcoin exchange

The attempted come back of CoinEx, China's forked-Bitcoin exchange
Written by Shuyao Kong
Published by decrypt.co
An interview with Haipo Yang, a crypto OG who’s trying to reposition his Bitcoin Cash-based CoinEx exchange. And more, in this week’s da bing.
https://preview.redd.it/h5f3i3lldv051.jpg?width=3200&format=pjpg&auto=webp&s=09b8696303ae5c6170753cc438929ebe520d4605
Haipo Yang, founder of ViaBTC, one of the largest mining pools in the world, and CoinEx, a crypto exchange known for its focus on Bitcoin Cash-based trading, is a well-known but relatively quiet character in China’s crypto circle. Typically, Yang doesn’t talk that much about his journey launching the mining pool, nor about CoinEx, which launched in December 2017.
And he almost never speaks about his fervent support for BCH, a hard fork of Bitcoin, and his now even more enthusiastic belief in BSV.
Yet that’s changing of late. Yang has been more active in recent months, participating in interviews about CoinEx and tweeting more frequently on Weibo, China’s Twitter. He’s been making controversial statements predicting the death of BTC, while supporting BCH and BSV on social media.
Recently, Yang told me that as a developer rather than a business person, he’s never been comfortable speaking in public. However he’s making an effort now to help publicize his renovation of CoinEx. So, for this week’s da bing, I decided to chat with him and get a peek into the mind of a veteran crypto entrepreneur who’s trying to make a personal, as well as a platform, comeback.

CoinEx’s golden opportunity

The first hard fork of Bitcoin occurred in August, 2017 and created a new cryptocurrency called Bitcoin Cash. The fork was prompted by partisans, including Yang, who wanted bigger block sizes on the blockchain — the basic idea was that bigger blocks would enable more transactions per second and make Bitcoin Cash something people would actually use to buy things, rather than Bitcoin’s more commonly perceived use as a store of value.
Yang added a tremendous amount of value to the mining scene in China. As a technical founder with has years of experience in big tech firms such as Tencent, Yang is proud of his #buidl skills. He developed most of the code in the early days of VicBTC, which became one of the biggest mining pools to this day.
Not satisfied with owning just a mining pool,Yang conceived of CoinEx, which was born in December of that year, specifically to carry on the mission of the newly forked Bitcoin Cash blockchain. As he got swept up in Bitcoin Cash enthusiasm, he even said that “BCH is bitcoin.”
CoinEx’s strategy was BCH-focused from day one; BCH was its base currency, meaning you could use it to buy and sell other currencies, such as Ethereum and Litecoin.
Interestingly, Jihan Wu, the co-founder of Bitcoin Exchange — himself a famous BCH supporter — was a big investor in the exchange. That made me wonder why he, Yang, and many other OG crypto miners, were so passionate about BCH. Was it just about bigger block sizes?
“Bigger block size means more users and use cases,” Yang explained. The move to bigger block sizes was attractive to miners because they would facilitate more transactions. Miners make money on transaction fees, as well as mining blocks. Likewise, the network would arguably be more useful to people, who were looking for digital cash for every day use.
That especially resonated with many early hardcore Bitcoiners. Said Yang: “We really believe that Bitcoin should be a P2P cash vehicle rather than a store of value.”
This view probably sounds outdated to people who believe that Bitcoin’s value as cash is long gone, with solutions such as Lightning Network fulfilling that role. Instead, the new narrative for Bitcoin resides in its value, rather than utility. Yet Yang believed that the forked network would create far more opportunity
“We could invite influential companies to establish nodes and contribute to the network. This cannot be done with the original Bitcoin architecture,” he said.

CoinEx pivots

But from its inception, CoinEx struggled with adoption and was dwarfed by the bigger exchanges. Part of that had to do with the fact that BCH and “Bitcoin Satoshi’s Vision,” another Bitcoin hard fork, were both controversial. Critics pointed out that these networks are centralized in a few big mining pools, and 51% attacks are not out of the question.
So over time, though Yang’s exchange still maintains strong support for BCH and BSV, it began to add support for all the major currencies.
Finally, in January of this year, it announced a major upgrade, of… well, just about everything. It started to offer futures trading, leveraged trading, options trading, and over 100 token projects available to traders. It even rolled out its own blockchain, “CoinEx Chain” to support a new DEX, “CoinEx DEX.”

The seemingly sudden publicity of CoinEx should not come as a surprise, then. As BCH/BSV was being marginalized, Yang shifted his focus. He’s now trying to ride the wave of building a bigger, more dynamic exchange.
“Crypto exchanges are where value is discovered,” Yang told me.

CoinEx: TNG

Building an exchange isn’t done overnight, nor is re-building one. CoinEx is still competing with the giants such as Binance.
However Yang thinks his exchange will thrive by zigging when his competitors zag. As usual, CoinEx is taking a slightly different route, he told me.
Like what? “We will be listing 小币种,” he said, using the expression for “small token projects.” I cannot help but wonder if these “small token projects” are simply shitcoins, the trading of which is certainly not new.
Indeed, Yang said that he’s banking on the success of his new, public blockchain. “We are building a CoinEx Chain, a layer one protocol for DEX alone. Using our public blockchain, anyone can issue any token, at any time,” he said. He described the blockchain as “a real decentralized, token-issuance and transaction platform.”
This is the core of Yang’s plan and vision. He believes that centralized exchanges will be a bottleneck for crypto adoption because it contradicts crypto’s nature as a completely free and open infrastructure. Essentially anyone should be able to launch a token and trade it with anyone. Only by building DEXes can we achieve full decentralization, he says.

The Religious nature of Bitcoin, and forked Bitcoin

It’s his belief that Bitcoin should adhere to Satoshi’s original vision that led Yang to send yet another controversial tweet last week, which I will translate: “The early days of Bitcoin expansion are similar to religion. The religious fervor brings prosperity to the industry.”
By extension, Yang believes that the next generation of Bitcoin should provoke a similar “religious” fervor. That’s why he has slowly become more of a BSV advocate than a fan of Bitcoin Cash. Yang believes that “BSV has more religious connotations, despite its negative image.” (As most crypto people know, the controversial Craig Wright, who claims to be Satoshi Nakamoto, led the hard fork which created BSV. Consequently it is often met with skepticism and derision.)
“The early days of Bitcoin expansion are similar to religion,” said Yang. “The religious fervor brings prosperity to the industry.”
Crypto is famous for its tribalism. Many people choose one camp over another not for practical reasons but because of simple faith. Talking to Yang and reading his tweet brings a historic texture to the Bitcoin narrative. But crypto cannot survive on religion alone. One has to build. Hash might have been worshipped in the old days but now the crypto religion is all about the size of the congregation.
