Proposed changes

  • Issue

    • Debug API (TraceBlock, StandardTraceBlock) calls VerifyHeader of consensus engine with latest chainConfig.
    • After the KIP-71 config has been updated, if you call the API with previous block number then it verify the header with latest config, not the config at the block number.
    • It cause the incorrect validation for the header.

  • Propose

    • Getting the config at the block number by governance in verifyHeader of the consensus engine.
    • Copying the latest ChainConfig and update the KIP-71 config.

  • Notes

    • The ChainConfig cannot be directly updated because the ChainConfig.governance.KIP71Config is a pointer.
    • The side effect will be affect other operations as well.

The performance impact (compared to directly using chain.Config()) should be minimal because ReadGovernance() is cached.
