Overview

• Binance Chain is set to undergo a hard fork upgrade on July 19th at 6:00 UTC.
• The upgrade, dubbed “ZhangHeng,” will focus on improving overall security.
• It will introduce BEP-255 to track user balance changes and fix the vulnerability of ‘Rogue Key Attack.”

BNB Chain 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,” named after a Chinese scientist, will occur at block height 328,088,888. A hard fork is a change to the software protocol that makes previously invalid blocks/transactions valid, or vice-versa. While the upgrade primarily focuses on improving overall security, it will have no direct impact on most users unless their exchange or wallet service notifies them otherwise. Full node operators must upgrade their software version to v0.10.16 before reaching the hard fork block height or they won’t be able to connect or send transactions. There will be no issuance of new BNB tokens during this process and two-thirds of all BNB Chain validators are required to upgrade their nodes for a smooth transition during the hard fork.

Security Enhancements

The project announced two major security changes in the ZhangHeng upgrade which includes introducing BEP-255 and fixing vulnerability called ‘Rogue Key Attack’. BEP-255 proposes an on-chain asset reconciliation system which tracks user balance changes in each block and reconciles them in order to identify issues while Rogue Key Attack could jeopardize the correctness of Fast Finality mechanism if not fixed properly.. To address this issue all existing vote addresses will be removed when the height of the hard fork is reached leaving validators to add vote addresses again.. Developers noted that these improvements were made in order to improve cross-chain security such as BEP171 and guarantee better security for assets on the chain especially after bridge exploitation occurred earlier this year.

Conclusion

The upcoming ZhangHeng Hard Fork Upgrade promises enhanced safety features for users of BNB Beacon Chain by introducing new protocols such as BEP-255 and fixing vulnerabilities like Rogue Key Attack as well as potentially increasing cross-chain security measures through implementation of protocols like BEP171 . Full node operators must remember that they need to update their software version before reaching block height 328,088,888 in order for their node to sync with peer/validator nodes correctly . This should allow for a smoother transition during this hardfork while also hopefully making sure user’s assets remain secure throughout any future exploits or risks faced by using this platform .

Takeaway

The upcoming ZhangHeng Hard Fork Upgrade promises improved safety features such as introducing new protocols like BEP-255 and fixing vulnerabilities like Rogue Key Attack thereby increasing cross chain security measures such as implementing protocols like BEF171 while full node operators must remember that they need update their software version before reaching block height 328 088 888
