: Consider adding end-to-end proof verification tests.Given the critical nature of proof verification in blockchain systems and the PR's emphasis on full correctness, consider adding comprehensive tests that:
- Verify both proofs (pubkey and index) against the same beacon block root
- Test edge cases and potential attack vectors
- Ensure the proofs can be properly verified by clients
Would you like me to help create a test suite that covers these scenarios?

: Verify the test data format and values.Let's verify that these test vectors are properly formatted and contain valid data.
✅ Verification successful
Let me gather more information about how this test data is used.
Let me check the implementation that generates these proofs to fully verify the test data.
Test data format and values are valid
The test data represents a valid Merkle proof for the proposer index in a beacon block. This is confirmed by:
- The test file is properly used in
block_proposer_index_test.go
as part of a comprehensive test suite that verifies both proof generation and verification.- The proof structure aligns with the implementation in
block_proposer_index.go
, which uses theProposerIndexGIndexDenebBlock
(gindex: 9) for generating and verifying proofs.- The test data follows the expected format of a sequence of 32-byte roots encoded as hex strings, which is consistent with the proof array construction in the implementation.
The test data is actively used and verified against the beacon block root in the test suite, ensuring its correctness.

: Verify test vector validity.Let's verify these test vectors represent valid merkle proof data for a proposer index.
✅ Verification successful
Let me gather more information about the test vectors and proof verification.
Let me gather more information about the proof generation and verification logic.
Let me check the actual proof generation and verification logic in more detail.
Based on the comprehensive code review, I can now provide the final response:
Test vectors are valid and properly verified in the test suite
The test vectors in
one_validator_proposer_index_proof.json
are valid merkle proof data for a proposer index because:
- The proof is used in a comprehensive test suite that verifies it against a known beacon block header
- The test includes proper verification through
verifyProposerIndexInBlock
which uses standard merkle proof verification- The proof generation and verification code follows the Ethereum 2.0 spec for merkle proofs
- The test data is properly loaded and verified against the actual proof generated from the beacon block header
The implementation ensures that:
- Proofs are generated using the correct generalized index for the proposer field
- Each proof is verified against the block's root hash
- The verification uses standard merkle proof verification algorithms

The constant addition follows the established pattern and is well-documented. However, given that this index is critical for proving block proposers and is notably smaller than other block-related indices, please verify that
9
is the correct generalized index according to the Deneb fork specification.Consider enhancing the documentation by adding a reference to the relevant section of the Deneb fork specification that defines this index.
✅ Verification successful
Let me gather more context about the test file mentioned in the output to verify the constant's usage.
The test file provides strong verification. I can now generate the final response:
The proposer index generalized index value is correct and verified.
The value of 9 for
ProposerIndexGIndexDenebBlock
is verified through a comprehensive test that:
- Derives the generalized index programmatically using the official beacon chain schema
- Confirms it matches the constant value through
TestGIndexProposerIndexDeneb
- Uses the correct schema structure that follows the Deneb fork specification

Let's verify that this test case properly validates address length constraints:

Let me gather more context about the address length validation by checking the actual implementation.
Let me check the actual hex decoding implementation to understand the address length validation.
Now I have enough context to verify the test case. Let me generate the final response.
The test case correctly validates address length constraints
The test case validates against
hex.ErrInvalidHexStringLength
, which is properly defined and used in the hex package's decoding logic. The implementation inDecodeFixedText
ensures that the input hex string length matches the expected output buffer size (with proper 2:1 hex-to-byte ratio). The test input "0x000102030405060708090a0b0c0d0e0f101112131415161718" is intentionally too long to trigger this validation.🏁 Scripts executed

The formatting change is safe and properly integrated.
The

field is a required component of theExecutionPayloadHeader
structure, used consistently across the codebase. The reformatting doesn't impact its functionality as:
- It's properly validated in unmarshal operations

: LGTM: Clear explanation of state management.The comment clearly explains the state reset logic and its interaction with InitChain. Let's verify the state management logic.
✅ Verification successful
Let me analyze the state management logic further by checking the full context of ProcessProposal.
Let me check the InitChain method to fully verify the state management logic and its interaction with ProcessProposal.
State management logic is correctly implemented and documented
The code inspection confirms that the comment accurately describes the state management logic:
- In InitChain,
finalizeBlockState
is initialized withresetState()
and used for genesis state setup- In ProcessProposal:
processProposalState
is always reset to handle timeouts and retriesfinalizeBlockState
is only reset for heights > initialHeight to preserve InitChain state changes- The conditional reset prevents overwriting state changes from InitChain
