Issue
This pull request adds the initial version of Staged DNS Sync, which is a new feature for syncing in sequential stages. The idea of staged sync is given from Erigon, which could improve the performance of full syncing in ethereum.
Each stage is executed in order, and a stage N does not stop until the local head reaches for it. As it is shown in the link below, the current implemented staged DNS sync has 6 stages and a couple of new stages could be added later.
https://app.diagrams.net/#G1GsetJ4hQDWnQGdGh6lcZA0MT4s9uihZo
This PR is same as the PR #4253 which is rebased with main.
Current stages are:
Heads: Retrieve Chain Heads
BlockHashes: Download block hashes
BlockBodies: Download block bodies
States: Insert new blocks and update blockchain states.
LastMile: update status for blocks after sync and update last mile blocks as well
Finish: Final stage to update the current block for the RPC API.
Features:
1.5X faster full sync compared to current legacy syncing
100% backwards compatible
Can be used in the main net without any changes to the current main net structure.
Efficiently using of CPU and RAM and Bandwidth
Using Erigon DB
Using single/multiple transactions to read/write date from/to db
Supporting of memory and disc DB, based on node specs
Can resume syncing after any crash
Fully configurable to sync in a single cycle or multiple cycles
More stable against network issues, because a few stages can be run offline
Improvements in peer randomized selection
Test
Simply run a node and wait for it to be synced.
Test/Run Logs
Operational Checklist
NO
Staged sync is fully backward compatible and there is no need to touch anything in the main net. Any node that uses the new version will be able to use it.
Tested simply by running a node and monitoring syncing for a couple of hours.
NO
It will use the CPU and bandwidth more efficiently.
