In app/rpc/namespace directory, the method to get blockHash is:
blockHash := common.BytesToHash(block.Block.Header.Hash())
but in tendermint, the method to get blockHash is:
tendermint/state/execution.go:284

	// Begin block
	var err error
	abciResponses.BeginBlock, err = proxyAppConn.BeginBlockSync(abci.RequestBeginBlock{
		Hash:                block.Hash(),
		Header:              types.TM2PB.Header(&block.Header),
		LastCommitInfo:      commitInfo,
		ByzantineValidators: byzVals,
	})

Header.Hash() will not include LastCommit *Commit info!
The current method will introduce #721 error.
