Bitcoin Cash Hard Fork

Bitcoin Cash Hard Fork

Bitcoin Cash Hard Fork | Segwit Recovery & Schnorr Signatures

A Bitcoin Cash hard fork was implemented earlier today as of block 58268. Although the network-split initially met with a hiccup, the upgrade has now successfully completed.

Bitcoin Cash Hard Fork

The hard fork sees the Bitcoin Cash network implement two new features. They are Segwit recovery and Schnorr signatures.

The Segwit recovery means network participants can now recover funds that were sent accidentally to Segwit addresses.

Before today, this was impossible due to the “enforcement of the new CLEANSTACK rule” which was implemented in the last upgrade in November.

The second new feature is the Schnorr Signatures. This is a digital signature scheme that allows for complex signing abilities.

According to news.Bitcoin.com:

“the basics of Schnorr signatures can slash roughly 4% off current transaction storage. In the future, after another Schnorr related upgrade, the scheme could provide for public signature aggregation and more complex sign-to-contract concepts”.

Segwit Recovery & Schnorr Signatures

Invented by Claus Schnorr, the signature scheme was patented for years and that patent has only recently expired. Now Bitcoin Cash developers have added the preliminary basics of it to the main chain.

The Schnorr scheme means multiple parties can transact with simple multi-party “aggregation schemes”. At 64 bytes, Schnorr signatures are smaller than the traditional ECDSA signatures which run at 70 bytes in size. The overall scalability of the network will be enhanced when further upgrades and the
“implementation of public signature aggregation” are enabled. Predictions suggest the network’s scaling abilites could be improved by reducing blockchain storage and bandwidth by 20-25%.

NewsBitcoin.com explains further:

“When Schnorr is combined with concepts like pay-to-public-key-hash (P2PKH) addresses and the recently added opcode OP_CHECKSIG, other benefits can be added to transactions like privacy and decision-based smart contracts”.

Bitcoin Cash 

With a market capitalization of over $6 billion USD, Bitcoin Cash is the fourth largest cryptocurrency in the world.

Are you a Bitcoin Cash holder? Are you excited by the upgrade to the network?

Bitcoin Cash Hard Fork Controversy

Hard forks and lack of governance were a huge issue during the rise of cryptocurrency back in late 2017. It seems this hasn’t changed in 2018, as we have just encountered a new Bitcoin Cash hard fork controversy.

Hard forks are required for large blockchain network updates and require all nodes running the network to switch over to the new chain at a designated block number. Unfortunately, not every node running the network agrees with the direction of the project and decides to start its own fork with other nodes—creating a new ‘forked’ chain and new digital currency.

Hard fork splits in 2017 brought about the digital currencies Bitcoin Cash (BCH), Bitcoin Gold (BTG), Ethereum Classic (ETC), Bitcoin Diamond (BCD), Monero Classic (XMC), and Monero Original (XMO).

Bitcoin Cash Hard Fork Controversy

On November 15th, Bitcoin Cash underwent its second scheduled protocol upgrade. However, a competing proposal emerged that was not compatible with the original roadmap and caused the BCH community to be split into three fractions: Bitcoin ABC, Bitcoin Unlimited, and Bitcoin SV.

Bitcoin ABC represents the conservative approach to the update, which aims to preserve Bitcoin Cash from radical changes. ABC is led by Roger Ver, CEO of Bitcoin.com. Bitcoin ABC is also backed and represented by Binance, Coinbase, and Bitmain.

Bitcoin SV, or Satoshi’s Vision, was founded last Friday by a blockchain firm that is associated with Craig Wright—who has in the past deemed himself as Satoshi Nakamoto and has often been mocked by the crypto community. Bitcoin SV seeks to increase the block size of BCH from 32MB to a max of 128MB in hopes of increasing the network’s capacity and scale.

Bitcoin Unlimited is a neutral fork and the leaders are looking for a compromise between Bitcoin SV and Bitcoin ABC, asking for a vote between all the miners.

Hash War: Who’s Winning?

Currently, Bitcoin ABC has the most support but Craig Wright isn’t backing down.

This just shows the need for proper governance and voting within these blockchain projects, because this Bitcoin Cash hard fork controversy has become a circus.

Bitcoin Cash Hard Fork Approaches

A Bitcoin Cash hard fork will happen on Thursday, November 15th.

Bitcoin Cash is already a hard fork of Bitcoin and has since grown to become the fourth-largest cryptocurrency. Now the digital currency will split in two, creating a second cryptocurrency.

The two digital currencies go by the names Bitcoin ABC, which is the continuation of the current or core Bitcoin Cash, and Bitcoin SV, which will follow new rules and stands for Satoshi’s Vision.

Bitcoin Cash Hard Fork

A hard fork occurs when network participants no longer agree on a proposed change to the running of the blockchain. This change is implemented via a software update.

Participants will decide what they agree with and when the fork happens, those that wish to adapt to the new rules will upgrade to the new software and those that don’t won’t upgrade their network.

The result is a split network. This means two separate blockchains, each running on different rules and with their own currency. Therefore, there will now be two separate digital currencies.

What Happened?

This Bitcoin Cash hard fork has come about after developer Amaury Sechet proposed an upgrade that made a small change to transaction ordering.

An escalating disagreement ensued and two well-known crypto personalities—Roger Ver and Craig Wright—ended up pitted against each other.

Ver is in support of the new software upgrade (Bitcoin ABC), but Wright favors a move more reflective of the original Bitcoin whitepaper (Bitcoin SV), which seeks to raise the maximum block size to 128MB from 32MB.

Hash Power and the Bitcoin Cash Hard Fork

The computing power needed to mine cryptocurrency is called ‘Hash Power.’ Hash power is important because the success of each coin will depend on where the miners commit their hash power to—Bitcoin ACB or Bitcoin SV. Currently, tallies are swaying in favor of Bitcoin ABC, but only time will tell.

Importantly, most major exchanges have stated support for the hard fork. This means owners of Bitcoin Cash will receive 1:1 per new cryptocurrency once the network upgrade happens.
