Description

This PR adds two changes to op-geth:

  1. support new api engine_opSealPayload, this is the associated PR to feat: add new engine_opSealPayload API  opbnb#248
  2. optimize several overheads in block mining to achieve higher TPS

Rationale

Through load test, we found that it took about 200ms(10k tps case) to call/serve of engine apis and some overheads in block minting steps can be optimized. So we try to optimize it to achieve higher TPS.

Example

n/a

Changes

Notable changes:

  • support new api engine_opSealPayload
# original block produce flow
1. op-node call engine_forkchoiceUpdated
2. wait scheduled time
3. op-node call sequentially: engine_getPayload -> engine_newPayload -> engine_forkchoiceUpdated

# new block produce flow using new engine_opSealPayload API
1. op-node call engine_forkchoiceUpdated
2. wait scheduled time
3. op-node call concurrently: engine_opSealPayloadResponse & engine_getPayload
  • optimized points in block mining steps
1. Build / FinalizeAndAssemble step: concurrent IntermediateRoot   and NewBlockWithWithdrawals
2. NewPayload / ExecutableDataToBlock step: cache Block in GetPayload API then get from cache instead of ExecutableDataToBlock
3. NewPayload / it.next(validateHead inside) step:  skip it.next if in minerMode
4. NewPayload / ValidateState step: async running ValidateState
5. ForkchoiceUpdate Head / getBlockByHash step: cache block in NewPayload then get from cache
6. ForkchoiceUpdate Head / setCanoncial step: concurrent writeHeadBlock and collectLogs
