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()

write

To write state diffs directly to a database:

eth-statediff-service write --config=<config path>

This depends on the database settings being properly configured.

Configuration
