Add broadcast validation routes to Beacon Node HTTP API (#4316)
## Issue Addressed - #4293 - #4264 ## Proposed Changes *Changes largely follow those suggested in the main issue*. - Add new routes to HTTP API - `post_beacon_blocks_v2` - `post_blinded_beacon_blocks_v2` - Add new routes to `BeaconNodeHttpClient` - `post_beacon_blocks_v2` - `post_blinded_beacon_blocks_v2` - Define new Eth2 common types - `BroadcastValidation`, enum representing the level of validation to apply to blocks prior to broadcast - `BroadcastValidationQuery`, the corresponding HTTP query string type for the above type - ~~Define `_checked` variants of both `publish_block` and `publish_blinded_block` that enforce a validation level at a type level~~ - Add interactive tests to the `bn_http_api_tests` test target covering each validation level (to their own test module, `broadcast_validation_tests`) - `beacon/blocks` - `broadcast_validation=gossip` - Invalid (400) - Full Pass (200) - Partial Pass (202) - `broadcast_validation=consensus` - Invalid (400) - Only gossip (400) - Only consensus pass (i.e., equivocates) (200) - Full pass (200) - `broadcast_validation=consensus_and_equivocation` - Invalid (400) - Invalid due to early equivocation (400) - Only gossip (400) - Only consensus (400) - Pass (200) - `beacon/blinded_blocks` - `broadcast_validation=gossip` - Invalid (400) - Full Pass (200) - Partial Pass (202) - `broadcast_validation=consensus` - Invalid (400) - Only gossip (400) - ~~Only consensus pass (i.e., equivocates) (200)~~ - Full pass (200) - `broadcast_validation=consensus_and_equivocation` - Invalid (400) - Invalid due to early equivocation (400) - Only gossip (400) - Only consensus (400) - Pass (200) - Add a new trait, `IntoGossipVerifiedBlock`, which allows type-level guarantees to be made as to gossip validity - Modify the structure of the `ObservedBlockProducers` cache from a `(slot, validator_index)` mapping to a `((slot, validator_index), block_root)` mapping - Modify `ObservedBlockProducers::proposer_has_been_observed` to return a `SeenBlock` rather than a boolean on success - Punish gossip peer (low) for submitting equivocating blocks - Rename `BlockError::SlashablePublish` to `BlockError::SlashableProposal` ## Additional Info This PR contains changes that directly modify how blocks are verified within the client.
