Binance Coin BNB: Hard Fork
Following the successful testnet upgrade, Binance Chain validators agree to have a scheduled hardfork upgrade at block height 20,300,000. Based on the current block generation speed, it is forecasted to be around 2019/07/15 7:00 AM (UTC). The validators and all the full node runners are expected to switch their software version to v0.6.0 by 2019/07/10.
What is a hardfork?
The cryptocurrency mainnet operates according to certain rules. To improve network performance or correct errors, changes are periodically introduced into it. A hard fork represents changes that are not compatible with previous versions of software supporting the cryptocurrency network. In order to continue to mine the cryptocurrency, miners need to update the software.
In some cases, as a result of a hard fork, a completely new cryptocurrency may appear, as happened with Bitcoin Cash and EthereumPoW.
