BNB Chain is ready to bear a tough fork improve referred to as Planck at block top 27,281,024 — at present slated for April 12. This improve will introduce enhanced safety and improved stability to the community, the core crew stated.
The onerous fork is designed to implement safety enhancements proposed in BEP-171. This proposal goals to strengthen the cross-chain bridge between the 2 blockchains that kind a part of the BNB Chain community — specifically, the Beacon Chain and Sensible Chain. By way of the improve, BNB Chain hopes to enhance its blockchain community’s safety, effectivity, and interoperability.
In late 2022, BNB Chain fell sufferer to a significant hack — which was traced again to a flaw within the IAVL proof verification mechanism. This safety mechanism safeguards the cross-chain bridge, permitting customers to switch property between BNB Sensible Chain, BNB Beacon Chain and different networks.
The upcoming Planck improve will contain a migration from the susceptible IAVL proof verification to the more-secure bridge safety mechanism, referred to as ICS23 specification. Moreover, the improve will introduce a timer-lock mechanism for giant cross-chain fund transfers, in addition to the automated pausing of cross-chain channels within the occasion of solid proof detection or throughout emergencies, akin to reported hacks. These measures intention to bolster the safety of the BNB Chain community and higher shield person funds towards potential assaults.
To make sure a clean transition to the upcoming Planck improve, the BNB Chain core crew has referred to as on all stakeholders to arrange accordingly. Specifically, full node operators have been advised to obtain and compile the most recent software program, model v1.1.21, to allow the onerous fork.
