Now the receipt RLP format in our chain database is:
type receiptStorageRLP struct {
PostStateOrStatus []byte
CumulativeGasUsed uint64
Bloom Bloom
TxHash common.Hash
ContractAddress common.Address
Logs []*LogForStorage
GasUsed uint64
}In fact the below fields are unnecessary in database:
- Bloom
- TxHash
- ContractAddress
- GasUsed
because they can be derive from the transaction. Then format can be simplified to:
type storedReceiptRLP struct {
PostStateOrStatus []byte
CumulativeGasUsed uint64
Logs []*Log
}So we can encode the new receipt RLP with the new format. Then convert the old receipt RLP to the new format later.
