# ipld-eth-statedb

Implementation of the geth [vm.StateDB](https://github.com/ethereum/go-ethereum/blob/master/core/vm/interface.go#L28) on top of
[ipld-eth-db](https://github.com/cerc-io/ipld-eth-db), to allow us to plug into existing EVM functionality. Analogous to
[ipfs-ethdb](https://github.com/cerc-io/ipfs-ethdb) but at one database abstraction level higher. This allows us to
bypass the trie-traversal access pattern normally used by the EVM (and which ipfs-ethdb allows us to replicate ontop of our
Postgres IPLD blockstore in the "public.blocks" table) and access state and storage directly in the "state_cids" and
"storage_cids" tables.


Note: "IPFS" is chosen in the name of "ipfs-ethdb" as it can function through an IPFS BlockService abstraction or directly ontop of an IPLD blockstore, whereas this repository
is very tightly coupled to the schema in ipld-eth-db.
