Binance’s BNB Beacon Chain will implement new security features in its upcoming ZhangHeng hard fork.
The changes added with the ZhangHeng hard fork include asset reconciliation measures proposed under BEP-255. In order to safeguard user holdings, the blockchain will search for changes in account balances after every transaction. Subsequently, the BNB blockchain will carry out an asset reconciliation procedure by comparing the changes in balance and total token supply.
In case it encounters errors during the reconciliation process, the blockchain will stop producing new blocks. Unfortunately, the suspension on block production will affect the operations of bridges and also impact deposits and withdrawals on exchanges, with the developers noting,
“This drastic action is necessary to protect the chain and its users, so core developers and community members should investigate the issue as soon as possible.”
The landmark ZhangHeng update will be rolled out on July 19, 2023, at 6:00 UTC.
