# Light client tests

The purpose of this test-generator is to provide test-vectors for validating the correct implementation of the light client sync protocol.

Test-format documentation can be found [here](../../formats/light_client/README.md).

Root `next_sync_committee` in `attested_header` `LightClientUpdate` structures currently use different merkle proof root depending on the presence of `finalized_header`. By always rooting it in the same state (the `attested_header.state_root`), logic gets simpler. Caveats: - In periods of extended non-finality, `update.finalized_header` may now be outdated by several sync committee periods. The old implementation rejected such updates as the `next_sync_committee` in them was stale, but the new implementation can properly handle this case. - The `next_sync_committee` can no longer be considered finalized based on `is_finality_update`. Instead, waiting until `finalized_header` is in the `attested_header`'s sync committee period is now necessary. - Because `update.finalized_header > store.finalized_header` no longer holds (for updates with finality), an `is_better_update` helper is added to improve `best_valid_update` tracking (in the past, finalized updates with supermajority participation would always directly apply) This PR builds on prior work from: - @hwwhww at https://github.com/ethereum/consensus-specs/pull/2829 2022-04-29 16:22:26 +02:00
