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.
The cryptocurrency mainnet operates according to certain rules. To improve network performance or correct errors, it is periodically made changes. A hard fork is changes that are not compatible with previous versions of programs that support the cryptocurrency network and in order to continue to mine cryptocurrency, miners need to update the software.
In some situations, as a result of a hard fork, a completely new cryptocurrency may appear, as happened with Bitcoin Cash.
