Tracking: Full sync high-level roadmap

[akirillo]

Our current priority is to achieve full sync from genesis.

The state of progress is as follows:

• [x] Generic headers & block bodies downloaders
• [x] Generic database & codec abstractions (#66)
• [x] Generic mempool (#36)
• [x] P2P stack (#64)
• [x] EVM executor (#72)
• [x] Core syncing stages (headers, bodies, senders, execution) (#40)
• [x] Fuzzing & benchmarking foundations
• [ ] PoW / PoS consensus verification (#72) (#39)
• [ ] Execution verification (statetests) (#72) (#39)
• [ ] CLI for each component in the stage loop
• [ ] Testing P2P functionality during tracing at the tip & gossiping mempool transactions
• [ ] Testing JSON-RPC implementation for completeness & performance (#37)

Beyond full sync, we intend to begin by experimenting with optimizing disk I/O under random reads & writes. The following are some areas we intend to explore:

• Pre-fetching data to maintain a warm cache
• Statically analyzing blocks to predict storage accesses
• Pipelining / batching EVM operations

Finally, an ongoing and parallel workstream is maintaining high quality documentation around each of the crates and the project as a whole, including the Reth Book, which is intended to be an educational resource for onboarding Ethereum node developers to Reth.
