Tracking: Full sync high-level roadmap

[akirillo]

Our current priority is to achieve full sync from genesis.

The state of progress is as follows:

Tasks

Beta Give feedback

1. Generic headers & block bodies downloaders #391
   A-staged-sync C-enhancement +2
   
2. Generic database & codec abstractions (Tracking: DB #66)
3. Generic mempool (Tracking: Transaction Pool #36)
4. P2P stack (Tracking: P2P #64)
5. EVM executor (Tracking: Execution/Validation of blocks #72)
6. Core syncing stages (headers, bodies, senders, execution) (Tracking: Staged sync #40)
7. Fuzzing & benchmarking foundations
8. PoW / PoS consensus verification (Tracking: Execution/Validation of blocks #72) (Tracking: Eth chain tests #39)
9. Execution verification (statetests) (Tracking: Execution/Validation of blocks #72) (Tracking: Eth chain tests #39)
10. CLI for each component in the stage loop
11. Testing P2P functionality during tracing at the tip & gossiping mempool transactions
12. Testing JSON-RPC implementation for completeness & performance (Tracking: RPC support #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.

For a more detailed view on all development threads, you can try filtering for tracking issues.
