One of the main features of Erigon3 is moving most of the state content (i.e. account/storage/code) and its validity proof (i.e. commitment) to snapshot flat files. This architectural change requires deep modifications also to the data layout in the data storage (e.g. state history indexing) and a completely new access interface called Temporal KV (a.k.a. Data API).
Our implementation of RPC service must be changed to access the current state and the state history using such Data API, which can be used both in embedded (i.e. in-process) and standalone (i.e. out-of-process) modes of operation.
This is the main tracking issue. Individual issues are listed below:
