At approximately 4 pm EDT at block height 504031, the Bitcoin Cash (BCH) network successfully hard forked. The fork is a change to the decentralized currency's consensus rules and aims to upgrade the network's Difficulty Adjustment Algorithm (DAA).
The Bitcoin Cash Network Has Successfully Hard Forked
Bitcoin Cash Network Completes a Successful Hard ForkNovember 13 is a memorable day for bitcoin cash supporters, as the network is forking in order to fix the BCH blockchain's DAA. The primary development teams who have been working on the bitcoin cash protocol consensus change include Bitcoin ABC, Unlimited, Nchain, and XT developers. The original DAA applied to the BCH network allowed the currency to thrive but also produced wild hashrate fluctuations. After several DAA proposals were researched and tested by the above-mentioned development teams, the community chose to implement a DAA proposal from Bitcoin ABC's lead developer Amaury Sechet.
Bitcoin Cash Network Completes a Successful Hard Fork
At approximately 4 pm EDT at block height 504031, the Bitcoin Cash (BCH) network had successfully hard forked.
The new BCH consensus change hopes to adjust the difficulty to hashrate to target a mean block interval of 600 seconds. Alongside this, the DAA aims to make sudden difficulty drops and spikes avoidable. For instance, the network will adjust difficulty rapidly when the hashrate changes exponentially, while also avoiding feedback oscillations. Sechet's DAA is based on a 144-period simple moving average according to the ABC team.
"The difficulty is adjusted each block, based on the amount of work done and the elapsed time of the previous 144 blocks," explains the Bitcoin ABC development team.
Since the DAA hard fork, block times have been smooth and consistent.
The Bitcoin Cash DAA Should Keep Block Times Consistent and the Mining Ecosystem Honest
Essentially the consensus change means the new DAA should keep block times stable and consistent at roughly 10 minutes per block. So far this goal of 10-minute block intervals has come to fruition. Now that the fork has happened BCH network participants will wait and see what happens with miners who have been hopping back and forth between two chains. Many BCH supporters believe this will level the playing field and from here on out, as the BTC and BCH competition should be fair without any miners gaming the system.
