180-182: Confirm Deneb-specific blob gas validation logic
In the Deneb-specific validations, the check compares header.BlobGasUsed with header.GetGasLimit(). Ensure that this comparison aligns with the protocol specifications, as BlobGasUsed exceeding GasLimit might require additional considerations based on Deneb's rules.
Please review the validation logic to confirm its correctness.

The validateExecutionHeader function is correctly integrated within the genesis validation flow:
- It's called from
ValidateGenesisingenesis.goas part of the beacon module's genesis state validation - The validation occurs during
InitChainABCI call, ensuring the execution header is validated before the chain starts - The function's genesis-specific validations (zero parent hash, block number 0, etc.) align with the initialization flow

28-29: Enhance function documentation
The function documentation should be more descriptive about the expected format and validation rules.
29-36: Verify the usage of fork version validation
Let's verify where this validation is being used in the codebase to ensure consistent validation across all fork version checks.
✅ Verification successful
Based on the search results, I can now generate the final response:
Fork version validation is consistently used in genesis configuration
The isValidForkVersion function is only used once in the codebase at mod/consensus/pkg/cometbft/service/genesis.go for validating the fork version format in genesis configuration. This is the appropriate place for this validation as it ensures the genesis configuration has a properly formatted fork version before the chain starts.
Other fork version usages in the codebase are dealing with numeric fork version values (uint32) for internal protocol operations, which is different from the hex string format validation we're looking at.

39-58: Consider refactoring hash validations into a helper function
The hash field validations could be grouped into a helper function to improve code organization and maintainability.
38-101: Verify consistency with other consensus implementations
Let's verify if these validations align with other consensus implementations in the codebase.
✅ Verification successful
Let me gather more specific information about the genesis block validation across different consensus implementations.
Let me search for any other execution payload validation implementations to ensure completeness.
Based on the comprehensive analysis of the codebase, I can now provide the final response:
Genesis block validation is correctly implemented and consistent
The validation in validateExecutionHeader is properly integrated with the consensus mechanism:
- It's called by the genesis validation flow in
mod/consensus/pkg/cometbft/service/genesis.go - The validation rules are specific to genesis blocks (block number 0) and align with the broader consensus requirements
- The validations are consistent with other genesis-related validations across the codebase, particularly in state transition and validator handling

I think what you have is good enough, but please check the ETH spec whether they are supposted to be 0 at genesis.

These fields are introduced in EIP 4844, deneb in ExecutionPayload, I see this line in EIP4844 For the first post-fork block, both parent.blob_gas_used and parent.excess_blob_gas are evaluated as 0.
So I will put the validation for these to be 0.

🔇 Additional comments (14)

28-36: LGTM! Implementation aligns with requirements.
The function provides basic format validation for fork versions, which is sufficient given that fork versions are determined for each fork.
Note: Based on previous feedback, additional validation complexity is not needed at this time.
mod/consensus/pkg/cometbft/service/validate_deposits.go (2)
75-77: Consider adding maximum amount validation
While checking for zero amount is good, consider also validating against a maximum allowed deposit amount to prevent potential overflow issues or economic constraints violation.
39-85: Verify error handling in upstream code
The validation function returns detailed errors, but we should ensure these errors are properly handled by the calling code.
✅ Verification successful
Let me check how the error is propagated further by looking at the usage of the genesis function.
Let me try a different pattern to get the full context of the function.
Error handling is properly implemented
The error from validateDeposits is properly wrapped and propagated in the ValidateGenesis method, which is a standard genesis validation hook in the Cosmos SDK. The error is wrapped with additional context ("invalid deposits: %w") and combined with validation of other genesis components. This follows good error handling practices.

62-66: Optimize duplicate pubkey detection
Consider using string(deposit.Pubkey[:]) as the map key instead of hex.EncodeToString(deposit.Pubkey[:]) to improve performance by avoiding unnecessary string allocations.
Apply this diff:
- pubkeyHex := hex.EncodeToString(deposit.Pubkey[:])
+ pubkeyStr := string(deposit.Pubkey[:])
if _, seen := seenPubkeys[pubkeyHex]; seen {
return fmt.Errorf("duplicate pubkey found in deposit %d", i)

79-81: Ensure GasUsed is zero for genesis block
It's important to verify that header.GasUsed is zero for the genesis block, as no gas should be used in the genesis block.
Apply this diff:
// Validate numeric fields
if header.GasLimit == 0 {
return errors.New("gas limit cannot be zero")
}
+ // Ensure GasUsed is zero for genesis block
+ if header.GasUsed != 0 {

32-34: LGTM: Well-documented constant declaration
The maxExtraDataSize constant is properly documented and has a reasonable value for genesis block extra data.

1-35: LGTM: Well-structured license, imports, and constants
The license header is properly included, imports are well-organized, and the constant is clearly documented.

The validations for base fee and blob gas parameters are thorough and well-structured. The error message for blob gas comparison appropriately includes the actual values.

The hash validations are comprehensive and the code includes helpful comments explaining why certain validations (fee recipient, logs bloom) are skipped. The extra data length check is properly implemented.
Note: While the empty trie root could be defined as a constant, the current implementation is acceptable as per previous feedback.

45-56: Consider adding essential deposit validations
The current implementation is missing validations for:
- Withdrawal credentials
- Deposit amount
- Deposit signature
These are critical for ensuring deposit integrity.
Basic validations are done on the genesis State.
