Headers backward #9510

pinges · 2025-11-28T04:17:29Z

This pull request introduces several improvements and fixes related to snap sync.

Snap sync is using two pipelines now.

The first pipeline downloads the headers. The download is starting from a trusted pivot block. For mainnet that trusted pivot block is a safe block that was sent by the CL (FCU). Headers are downloaded backwards from that trusted block and each block can be validated using the parent block hash contained in the previous header. The last header downloaded is block 1, which is validated by the parent block hash of block 2, and in addition validated against the known genesis block by checking whether the parent block hash matches the block hash of the genesis block (block 0).
All headers are written to the database and are fully trusted at the end of the header download.
The second pipeline now uses the trusted headers to download the bodies and receipts. This download starts from the genesis block or a known checkpoint. Mainnet blocks and receipts by default are downloaded starting at the first block of the Paris hard fork. The first step of the second pipeline retrieves the headers from the database. Blocks and receipts are requested from peers and are validated against the block hash or the receipts root contained in the header.
The storing of the bodies and receipts was optimized by doing less validation as these are validated against fully trusted headers now.

Test and Configuration Enhancements:

Fixed BFT sync acceptance tests. BFT SNAP and CHECKPOINT sync tests now use snap.

Build and Miscellaneous Fixes:

Fixed test resource generation in the Gradle build script to only generate the test blockchain if the binary does not already exist.

Syncing Times compared to latest
*Chain download is 2-3 hours faster than latest, but as state download, heal is slower this does not make a big difference in total sync time.

* Add test summary reporting to block-test command The block-test command now tracks and displays a summary of test execution results, including total tests, passed/failed counts, and a list of failed tests with their failure reasons.
