Index Supply Node

[ryandotsmith]

The goal for the Index Supply Node is to have a narrowly focused Ethereum client that provides a few functions:

1. Convert logs into rows in a Postgres database
2. Serve eth_call requests for view functions
3. Some sort of EVM stack introspection / tracing

In other words, a node that is purpose built for reading Ethereum data.

The node should be a single binary with no system dependencies. It should fit in with other UNIX like tools. It should keep its state entirely within the Postgres database. It may leverage services like RLPS or the Portal (fka light client) network. It should not rely on any proprietary or closed source systems, companies, or services.

The work on Index Supply Node has already begun with a lot of the Ethereum implementation written from scratch. All of that code lives within this repository. However, it's a long road to completion and along the way we want to be providing value to teams who are building on Ethereum and desire simple, open source tooling. Hence E2PG and RLPS. Both of those tools will eventually merge into the Index Supply Node. But they can be used alongside existing tooling today.
