The BNB Chain is expected to undergo the Luban upgrade on June 12th.
BlockBeats reported on May 25th that BNB Chain will undergo a network upgrade called "Luban" at block height 29,020,050, with an expected time of 5:30 a.m. Beijing time on June 12th. The Luban hard fork includes three BEPs: BEP-126, BEP-174, and BEP-221. Validators and full node operators on the mainnet should switch their software versions to v1.2.4 before June 12th, 2023.
BEP-126 introduces the "Fast Finality" mechanism, which ensures that once a block is finalized on the network, it cannot be reversed. This reduces the possibility of bad actors attempting chain reorganizations. BEP-174 proposes "Cross-Chain Relay Management" to mitigate any potential security issues in the BSC bridge. BEP-221 proposes the "CometBFT Light Block Validation" system, which suggests adding new contracts to blockchain networks that use CometBFT technology.
