KSP Technical Analysis and Response to BNB Chain Hard Fork Upgrade
BNB Chain has just completed a network hard fork, upgrading the block generation speed from 3 seconds/block to 1.5 seconds/block. This change is significant and exposes certain design flaws in DeFi protocols regarding time handling. The following is KSP's technical analysis and response for the community and partners' reference.
1. Potential Impact of Hard Forks on Traditional DeFi Protocols
Block Time Assumption Failure
Many protocols roughly estimate on-chain time using "Block Height × Average Block Time". For example:
3 seconds/block × 28,800 blocks ≈ 1 day
If the original formula is still used after the upgrade, it will shorten the actual block time by half, leading to
