eth-statediff-service
standalone statediffing service ontop of leveldb
Purpose:
Stand up a statediffing service directly on top of a go-ethereum leveldb instance. This service can serve historical state data over the same rpc interface as statediffing geth without needing to run a full node
Usage
serve
To serve state diffs over RPC:
eth-statediff-service serve --config=<config path>
Available RPC methods are:
statediff_stateTrieAt()
statediff_streamCodeAndCodeHash()
statediff_stateDiffAt()
statediff_writeStateDiffAt()
statediff_writeStateDiffsInRange()
e.g. curl -X POST -H 'Content-Type: application/json' --data '{"jsonrpc":"2.0","method":"statediff_writeStateDiffsInRange","params":['"$BEGIN"', '"$END"', {"intermediateStateNodes":true,"intermediateStorageNodes":true,"includeBlock":true,"includeReceipts":true,"includeTD":true,"includeCode":true}],"id":1}' "$HOST":"$PORT"
The process can be configured locally with sets of ranges to process as a "prerun" to processing directed by the server endpoints.
This is done by turning "prerun" on in the config (statediff.prerun = true
) and defining ranged and params in the
prerun
section of the config as shown below.
