There was a problem hiding this comment.
would need to call ctx.GigaMultiStore().WriteGiga() here since giga cache isn't visible to v2 executor so need flushing
Fixed critical issues causing `LastResultsHash` mismatch between the
standard and giga executors, which was causing consensus failures when
running nodes with `GIGA_EXECUTOR` enabled.
The `LastResultsHash` is computed from only 4 deterministic fields of
each `ExecTxResult` (defined in `deterministicExecTxResult` in
`sei-tendermint/abci/types/types.go`):
- `Code`
- `Data`
- `GasWanted`
- `GasUsed`
The giga executor was producing different values for two of these
fields.
The giga executor was not setting `GasWanted` (defaulted to 0), while
the standard executor sets it to the transaction's gas limit.
```go
// Before: GasWanted not set (defaults to 0)
// After:
gasWanted := int64(ethTx.Gas())
```
The giga executor was putting raw receipt bytes in the `Data` field,
while the standard executor wraps `MsgEVMTransactionResponse` in
`TxMsgData`:
```go
// Before: Data = receiptBytes (raw marshaled receipt)
// After: Matches standard executor format
evmResponse := &evmtypes.MsgEVMTransactionResponse{
GasUsed: execResult.UsedGas,
VmError: vmError,
ReturnData: execResult.ReturnData,
Hash: ethTx.Hash().Hex(),
Logs: evmtypes.NewLogsFromEth(stateDB.GetAllLogs()),
}
txMsgData := &sdk.TxMsgData{Data: []*sdk.MsgData{{MsgType: msgTypeURL, Data: evmResponseBytes}}}
// Data = marshaled txMsgData
```
Added logging to aid future debugging of consensus issues:
| Level | Location | What's Logged |
|-------|----------|---------------|
| **Error** | `ValidateBlock` on mismatch | Expected vs got hash, block
height, numTxs, blockHash |
| **Info** | `ApplyBlock` after hash computation | Computed hash,
height, txCount |
| **Debug** | `ApplyBlock` per-tx | Code, GasWanted, GasUsed, dataLen
for each tx |
- `app/app.go` - Fixed giga executor `GasWanted` and `Data` field format
- `sei-tendermint/internal/state/execution.go` - Added LastResultsHash
debugging logs
Run a multi-node cluster with one node using `GIGA_EXECUTOR=true` and
verify blocks reach consensus without `LastResultsHash` mismatch errors.
- Set the txIndex correctly (ProcessBlock already does this) - Return ABCI codes

Describe your changes and provide context
This PR supports running a Giga node, in consensus with other non-Giga nodes. It only supports sequential execution for Giga, falling back to the v2 logic for cosmos and interop transactions.
