Merge Issue Tracking

[terencechain]

Spec:

• Pass consensus spec v1.1.9 spec tests
• Pass consensus spec v1.1.10 spec tests Spec test v1.1.10 #10298
• Pass bellatrix forkchoice spec tests #forkchoice Bellatrix fork choice spec tests #10284
• Rename receipt_root -> receipts_root
• Rename execute_payload -> notify_new_payload

Engine API:

• Support authentication for engine API Engine API Client Authentication for the Merge via HTTP #10236
• Use engine_exchangeTransitionConfigurationV1 to check EL config
• Handle nil cases andpayloadStatus invalid in respond
• Unify --execution-provider and --http-web3provider
• Better status, error and nil handling for responses
• Update to kiln v2
• Review endianess conversations. More places are doing this wrong
• Call fcu as part of processing attestations and updating head
• Log out time taken for calls to the execution node in the critical paths.
• Add in tracing for execution node calls.

Optimistic sync:

• Can optimistically sync beacon node under various scenarios
• Validator assignments are blocked under optimistic mode Optimistic sync: prysm validator rpcs #10200
• Can remove invalid SYNCING/ACCEPTED blocks
• Beacon APIs can properly respond under optimistic mode
• Optimistically import any post-merge block Optimistically import any post-merge block ethereum/consensus-specs#2844
• P2p scorer and gossip pub beacon block under optimistic mode Ignore gossip messages when in optimistic mode #10274
• Beacon block sync validation under optimistic mode Add new spec validations on the p2p layer in Bellatrix #10233
• Sync service should still pass block with optimistic parent to blockchain service
• Retrospective transition block checking
• Ensuring sync gracefully handles an offline EE (gracefully handle offline EE w/o penalizing innocent peers or wasting resources). Pause sync when execution layer is offline?
• Gracefully shutdown if a justified or finalized block has turned INVALID #10487

Web3signer

• add BLOCK_V3 mapping for web3signer refer to tracking issue Web3 Signer integration updates for merge #10053
• update Web3Signer binary for web3signer
• remove condition check in e2e that stops tests right before Bellatrix

Code health:

• Clean up process block with optimistic sync
• Cache eth1 hash and total difficulty for validator finding terminal transition block
• Set a max allowance for looking back to find terminal transition block
• Context timeout doesn't fail validator duty

UX:

• Add --kiln-testnet flag
• Complete fee recipient tasks Fee Recipient Feature Flag & APIs #10292
• Check for terminal block during proposer preparation Add transition blk proposer preparation #10497
• Don't call fcu update twice to propose block Payload ID caching #10481
• Investiate why payload ID cache hit/miss ratio is not 100%
• Improve logging.
  • Identify beacon block with non empty payload
  • Estimate time to TTD and log it
  • What else?

Testing:

• Support e2e test pass Bellatrix epoch and reach ttd
• Differential fuzz engine API req/res
• Test generator Bellatrix version block
• Transaction Generator for execution nodes.
• Configurable tool to trigger optimistic sync.

Eth2 API

• Update all the Bellatrix related beacon endpoints
• Update all the Bellatrix related validator endpoints
• Update all the Bellatrix related debug endpoints
• Add is_optimistic field to all relevant endpoints

Prysm API

• Update all the Bellatrix related beacon endpoints

Bugs

• Beacon block's eth1 data hash is 0s
• TTD checks are being bypassed in e2e
• If the execution engine has a restart, prysm stalls and does nothing.

Final:

• Cont merging kiln to develop (mostly go.mod changes)
