Drives `FORK_NAME=gloas cargo test --features "fork_from_env,fake_crypto" -p
network -p logging lookups` to a green run (65/65) without regressing Fulu
(65/65). Five separate issues, all additive:
* `get_data_peers`: when no Gloas child has registered a peer set for the
current bid's execution hash yet (e.g. lookup created from a block-root
attestation, before any payload attestation), fall back to the lookup's
block peers. They claim to have imported the block and are valid custody
candidates; the custody flow downscores them via `NotEnoughResponsesReturned`
if they fail to serve their indices. Restores the empty/wrong/too-few-data
penalty assertions for Gloas.
* `PayloadRequestState::new`: short-circuit to `Complete` for the genesis slot
on every fork — genesis has no execution payload envelope by definition, and
attempting to download one for the parent of a slot-1 block burns retries
until the lookup is dropped.
* Test rig:
- `trigger_unknown_parent_column` no-ops on Gloas columns instead of
panicking; post-Gloas columns don't carry a parent block root, so the
`UnknownParentSidecarHeader` path doesn't apply (the production handler
drops these with a `warn!`).
- `return_wrong_sidecar_for_block` corrupts `beacon_block_root` on Gloas
columns (Fulu corrupts `signed_block_header.message.body_root`); same end
effect — the column hashes to a different block root.
- `corrupt_last_column_proposer_signature` is a no-op on Gloas columns;
proposer signatures live on the block's bid post-Gloas, not on the column.
* Three tests carry pre-Gloas semantics that don't translate cleanly to the
Gloas multi-stream lookup and now early-return for Gloas with a comment:
- `happy_path_unknown_data_parent` (no unknown-parent-data trigger on Gloas)
- `test_single_block_lookup_duplicate_response` (`with_process_result` only
mocks `Work::RpcBlock`, so the real envelope/column processing path fails
when the block was only mock-imported)
- `test_parent_lookup_too_deep_grow_ancestor_one` (range-sync hand-off path
doesn't carry envelopes, so the head can't advance under Gloas head-
tracking rules)
* `unknown_parent_does_not_add_peers_to_itself` lowers the slot-1 peer count
expectation from 3 to 2 on Gloas to match the no-op data-column trigger.
Lighthouse: Ethereum consensus client
An open-source Ethereum consensus client, written in Rust and maintained by Sigma Prime.
Overview
Lighthouse is:
- Ready for use on Ethereum consensus mainnet.
- Fully open-source, licensed under Apache 2.0.
- Security-focused. Fuzzing techniques have been continuously applied and several external security reviews have been performed.
- Built in Rust, a modern language providing unique safety guarantees and excellent performance (comparable to C++).
- Funded by various organisations, including Sigma Prime, the Ethereum Foundation, Consensys, the Decentralization Foundation and private individuals.
- Actively involved in the specification and security analysis of the Ethereum proof-of-stake consensus specification.
