The beacon chain mainnet will undergo a hard fork upgrade at block height 328,088,888 on July 19, 2023, at 6:00 UTC. The upgrade will introduce BEP-255, which proposes on-chain asset reconciliation on the BNB Beacon Chain. This addition improves security by tracking user balance changes in every block and reconciling them to identify discrepancies. If there are any reconciliation errors, the blockchain will halt the production of new blocks. The upgrade also introduces a bug fix that addresses a vulnerability called the Rogue Key Attack, which could jeopardize the correctness of the network’s Fast Finality mechanism.
