    Recap of BCH advancements over BTC since fork

    Posted:

    There's been a whirlwind of innovation since bitcoin cash liberated itself from BTC over 3 years ago, it is hard sometimes hard to keep up. So in simple summarized paragraphs I just wanted to list what I know in the way of the main additions and improvements, especially for new comers

    Base protocol changes

    #1 Removal of 1mb limit on blocksize. Greatly Increasing the transaction capacity of bitcoin cash, massively improving transaction certainty and lowering fees. This also prevents transaction fee market like on BTC and enables rapid 0 confirmation transactions to have more security and certainty of success. It also allowing miners to dynamically choose what the blocksize limit should be based on their costs and hardware capabilities (which is always improving at a great rate). An important knock-on effect of high tx capacity/blocksize is the energy efficiency of BCH in terms of mining energy use per transaction confirmed, currently this is approx 100x lower than BTC (assuming price parity) and is improving all of the time.

    #2 Avoidance of segwit. Segwit was implemented on BTC in late 2017. It is a messy and overengineered way to increase the block size limit by a very small amount and prevent TX malleability on some BTC transactions (Tx malleability has been fixed on BCH much more cleanly with schnorr signatures) .Segwit changed BTC fundamentally from the bitcoin white paper definition of bitcoin as a "chain of digital signatures" and alters the incentives in the network as a whole.

    #3 Removal of Replace-by-fee (RBF) This "feature" was added to allow people to double spend BTC more easily, it was created because transactions often get stuck on BTC due to the prohibitively small blocksize. RBF makes 0 confirmation transactions completely untrustworthy so that BTC is far less safe to accept as a means of payment in small day-to-day transactions where speed matters. RBF has been used successfully to rob businesses out of BTC

    #4 Enabling op-codes To allow for smart functionality on bitcoin cash, like the creation of colored coins and representative tokens, alongside the ability to perform smart contracts, but in a more simplified and scalable manner than ethereum's solidity programming language. This has enabled BCH to be much more than just cash, it can now perform more complex financial and legal actions by acting as a decentralized, smart and low cost platform of trust.

    #5 Enabling Schnorr signatures. Schnorr signatures are a cleaner and more efficient way to sign and validate transactions, Schnorr signatures are provably non-malleable and allow multiple parties to collaborate to produce a signature that is valid for the sum of their public keys. This is the building block for various higher-level constructions that improve efficiency and privacy

    #6 Canonical Transaction Ordering (CTOR) This has many efficiency benefits, especially in the context of having very large blocks. Miners no longer need to discover a valid ordering saving About 70% of block template creation time. No need to worry about intermediate states during block validation. This ensures that block validation can be perfectly parallel [3]. Ethereum's scalability suffers from having a large number of intermediate states, for example. It makes encoding and transmitting blocks a lot easier by allowing nodes to communicate only the transactions that differ between their mempools and a recently published block. This is what Graphene [4] does, and it works very efficiently with CTOR. CTOR reduces system complexity, eliminating the entire class of attack vectors where a malicious miner can publish a large block with a transaction ordering that is as slow to validate as possible. Read in depth here

    #7 Graphene Graphene, at a high level, is an efficient means of communicating new blocks to the network. The content of blocks, transactions, must be validated by others on the network. The validation process takes some time and some of the validation done by nodes can be unnecessary or redundant, slowing down block propagation. Making this process more efficient and squeezing out bottlenecks can allow bigger and bigger blocks of transactions to flow throughout the network without issues. A more efficient means of propagation means the possibility for greater transaction throughput in the future. The graphene protocol makes use of two technologies: bloom filters and invertible bloom look up tables (IBLTs). These technologies help reconcile between what a node already knows and what information it needs to know from another node. Previously, without the help of Graphene, nodes were communicating blocks to others by dumping all of the raw transaction data on them without taking into account what the node they're communicating with already knows. Read in depth here

    Secondary Protocols

    #1 Cash shuffle & Cash Fusion compliment each other to enable privacy/fungibility of transactions on BCH. CashShuffle is a protocol for allowing users to combine their transactions with others, creating obfuscation. It builds upon CoinShuffle and adds a matching service. As such, it is a more complete and usable protocol. Cash fusion is Trustless, obfuscated coin consolidation.

    #2 Simple-ledger-protocol The simple ledger protocol (SLP) is a token protocol for the Bitcoin Cash network, that enables anyone to create and manage tokens on-chain. The simple ledger protocol is arguably the simplest and easiest to use token token creation system across all blockchains yet. SLP tokens can easily be created, traded, and managed on the Bitcoin Cash blockchain within seconds for fractions of a penny per transaction.

    #3 Smart-BCH Smart Bitcoin Cash is a sidechain for Bitcoin Cash and has an aim to explore new ideas and unlock novel possibilities. By developing optimized, high-throughput and hardware-friendly libraries compatible with the de facto standards of smart contracts, DeFi applications can be easily migrated into Bitcoin Cash's ecosystem and run fluently at low cost. It is compatible with Ethereum's EVM and Web3 API and provides high throughput for DApps in a fast, secure, and decentralized manner.

    #4 Local.bitcoin.com Local Bitcoin is a private peer-to-peer platform where you can find others who are interested in trading BCH for local currencies, It is completely non-custodial and enables trades via a blind escrow smart contract.

    #5 Cash Accounts https://www.cashaccount.info/ - You can send Bitcoin Cash to an easy to remember alias such as Eric#100 instead of the difficult to remember Bitcoin Cash wallet address.

    #6 Scalenet https://np.reddit.com/r/btc/comments/j66eh8/scalenet_and_testnet4_are_online_and_open_for/ - Bitcoin Cash is doing the ground work to cater for Visa/Mastercard volumes level and then to be used by the entire world.

    #7 Mainnet.cash - Making things easy for developers to start building on Bitcoin Cash. The codes are very simple to understand for new developers.

    #8 Any hedge Decentralized derivative markets the first DeFi product on BCH

    #9 Flip starter Peer to Peer crowdfunding

    #10 Detoken A trustless, limitless and secure platform for accessing peer-to-peer financial products from anywhere in the world. https://detoken.net/

    Smart Contract languages

    #1 CashScript CashScript is a high-level programming language for smart contracts on Bitcoin Cash. It offers a strong abstraction layer over Bitcoin Cash' native virtual machine, Bitcoin Script. Its syntax is based on Ethereum's smart contract language Solidity, but its functionality is very different since smart contracts on Bitcoin Cash differ greatly from smart contracts on Ethereum. For a detailed comparison of them, refer to the blog post Smart Contracts on Ethereum, Bitcoin and Bitcoin Cash.

    #2 Spedn Spedn is a high level smart contracts programming language for Bitcoin Cash. It is designed for explicitness and safety (still in development)

    I watched both. The original was 3 hours. I didn't finish it at my office, went home, and was going to watch the rest during dinner, only to find the a-holes had already clipped it. Thanks to the rescued copy I could finish, and Jimmy provided enough salty tears to season my fries.

    Bch sent to my dad for the first time

    Posted:

    I owed my dad some money, and decided I'd try to pay him back using the Bch I had. He sent me his address, and I sent him $500. The fee was .0000071 sats, and he got it in about a minute. Now he can use that for what ever he wants. He's been in crypto for just a short time, but it's really cool to see him accepting it so quickly and wanting to learn and see how it works. I live the crypto abilities

    Does BCH 0-Confirmation Work In The Real World?

    Posted:

    Yes BCH's

    Today I thought I would find out.

    1. Waited for a block to be Mined on the BCH chain

    2. Bought a Costa UK Gift Card with the Android Bitpay wallet (it will instantly give you the Gift Card, this is 0-Conf)

    3. Instantly went to the counter and used said Gift Card to buy a Coffee

    4. I was out the door enjoying the Coffee all before the next block had been found.

    I don't think it gets clearer than that, 0-conf Works Today, In the Real World

    But don't take my word for it verify it yourself.

    Typical M.O. of a Core Maxi - Inability to admit when they are clearly wrong!

    Posted:

    From this thread

    WOW $44 million sent securely for less than a penny. BitcoinCash BCH is open source money. link

    Core Maxi: == u/diradder

    BCH bagholder: == your humble servant

    Core Maxi: It currently has 22 confirmation.

    Mathematically it still needs ~700 confirmations (about 5 days) before you can consider it as "securely" received (immutable) as a Bitcoin transactions with 6 confirmations (which takes ~ 1 hour)... (source, mathematical explanation).

    BCH bagholder: Q How much hash power would it take so that my node no longer recognises that transaction once it has more than 10 confirmations?

    Core Maxi: I think you should check the link above with the explanation before so triumphantly and wrongly pretending BCH is secure.

    BCH bagholder: A: (for those that might not know) There isn't enough hash power on earth. Now or Ever1

    Core Maxi: This is wrong.

    BCH bagholder: You should probably read + understand the Qestion I posed a bit better before you start throwing around words like wrongly, heh heh.

    After 10 blocks have been mined on top of Block A my node will no longer (without human intervention) accept any chain that doesn't contain Block A regardless of hash power. (aside - Block A is the block that contains the $44 Million tx)

    Core Maxi: Oh yeah, because BCH is just a bastardized chain pretending to care about Proof-of-Work but instead relying on 10-blocks rolling-checkpoints, I always forget this point, if you see what I mean... thanks for pointing this out ;)

    BCH bagholder: so you were wrong, try not to let your biases blind you so much in the future.

    Core Maxi: Think what you want,

    BCH bagholder: the fact is you comically made a bold claim

    bold claim: I think you should check the link above with the explanation before so triumphantly and wrongly pretending BCH is secure.

    BCH bagholder: which was demonstrated to be in error and now you are deflecting 'oh I forgot' rather than holding up your hands and saying yes I was wrong - I don't think I have come across a Core Maxi that was capable of this simple act.

    Core Maxi: It isn't "demonstrated" to be an "error", it's a voluntary omission on my part to be able to compare both chains on a common ground and not lose most non-tech savvy people with irrelevant details when it comes to actually comparing those chains.2

    BCH bagholder: heh heh, you wriggle and you wriggle - as I said it seems impossible for a Core Maxi to admit when they deride someone else for being wrong and it turns out that they were wrong in the first place delicious.

    The primary reason for posting this is to show others how the likes of u/diradder though seemingly knowledgeable has a fatal flaw

    • they are incapable of admitting that they are wrong even when it is clearly pointed out they wriggle and wriggle. I have found this to be a common trait with just about all these Core Maxi's some know a bit more than others, but seem to be incapable of good faith discussion. They are usually blinded by their Bias - something us BCH bagholders should watch out for in ourselves.

    Is u/diradder knowledgeable about the technicalities of SHA256 PoW blockchains absolutely, can you trust them......

    I pointed out to u/diradder

    BCH bagholder: Do you not see that this inability to admit being wrong undermines any knowledge you might bring to us poor BCH bag holders not to mention stunting of your own growth in the understanding of PoW coins through open and honest discussion with perhaps even less knowleadgeable people - but of it seems they are too full of hubris to contemplate they might have something to learn from us bag holders.

    archive link in case of 'data corruption' as per the Kim Dot Com Clubhouse Debacle

    1. yes the Ever is hyperbole and probably wrong

    2. it's a voluntary omission on my part to be able to compare both chains on a common ground - this has no bearing on whether all the hash power on the planet could force my node to accept a chain that does not contain block A
