• BNB Beacon Chain, the Binance blockchain ecosystem, is set to undergo a hard fork upgrade on July 19th at 6:00 UTC.
• This hard fork will introduce enhanced security features for users, such as BEP-255 and a bug fix to address the Rogue Key Attack vulnerability.
• All existing vote addresses will be removed when the height of the hard fork is reached.

BNB Chain Hard Fork Upgrade

The BNB Beacon Chain, the Binance blockchain ecosystem, is expected to undergo a scheduled hard fork upgrade on 19th July at 6:00 UTC, with enhanced security features for users. The hard fork dubbed “ZhangHeng” will occur at block height 328,088,888 and no new tokens will be issued. Full node operators must upgrade their software version to v0.10.16 before reaching the block height in order for their nodes to sync with upgraded validator nodes.

Enhanced Security Features

The upgrade primarily focuses on improving overall security through introducing two major changes: BEP-255 and addressing the Rogue Key Attack vulnerability through removing all existing vote addresses when the height of the hard fork is reached. BEP-255 proposes on-chain asset reconciliation that tracks user balance changes in each block and reconciles them to identify any issues; if there are any errors detected then it will ‘panic’ and prevent production of new blocks until resolved. As for Rogue Key Attack vulnerability, it could potentially jeopardize correctness of Fast Finality mechanism of network; by removing all existing vote addresses when the height of the hardfork is reached it can help prevent this attack from occurring in future blocks or transactions.

Impact On Users

The full node operators must upgrade their software version in order to sync with upgraded validator nodes; however other than node operators most users do not have take any additional action unless instructed by their exchange or wallet service provider as this update primarily focuses on improved security rather than functionality which won’t have direct impact on them..

Cross-Chain Security Improvements

Apart from these two major security enhancements mentioned above there have also been improvements made in cross-chain security such as via BEP171; however developers noted that this does not guarantee assets safety completely especially after bridge exploitations hence why they also focused on improving security within beacon chain itself through introducing aforementioned changes via ZhangHeng Hard Fork Upgrade .

Conclusion

In conclusion, ZhangHeng Hard Fork Upgrade coming up later this month aims to improve overall security within Binance Blockchain Ecosystem mainly by introducing new protocols such as BEp-255 and resolving Rogue Key Attack vulnerability while also making some improvements cross chain securities via BEp171; however most users do not need take any additional action unless explicitly asked by exchange/wallet service provider while full node operators should upgrade their software version before reaching block height corresponding to date & time of scheduled Hard Fork Upgrade i.e 19th July 6:00 UTC
