- 1-36: The
ChainParamsfunction is well implemented. It correctly initializes theparams.ChainConfigstructure with the providedobscuroChainIDand sets all fork blocks togethcommon.Big0. This implies that all Ethereum protocol upgrades are immediately available from the genesis block. The timestamp fields are also correctly set to zero. Ensure that this configuration aligns with the intended behavior of the Obscuro network.integration/simulation/network/network_utils.go (1)
- 94-98: The
GasLimitvalue has been significantly increased. Ensure that this change is compatible with the rest of the system and won't cause any issues such as out-of-memory errors or transaction failures due to exceeding gas limits.go/common/gethencoding/geth_encoding.go (3)
7-15: New import statements have been added. Ensure that these packages are included in your dependencies.

1-14: The import statements are well organized and separated by functionality. Good job.
16-22: The
TxPoolstruct is well defined with clear field names. Good job.24-34: The
NewTxPoolfunction is well implemented. It initializes a newTxPoolinstance with the necessary fields.36-50: The
Startfunction is well implemented. It checks if the pool is already started before initializing a new one. This prevents overwriting an existing pool.52-55: The
PendingTransactionsfunction is well implemented. It retrieves all pending transactions from the pool.go/enclave/ethblockchain/eth_blockchain.go (6)
24-30: The previous comment about using an interface for the logger is still valid. This would make the code more testable and flexible.
33-41: The previous comment about validating function parameters before using them is still valid. This would prevent potential nil pointer dereferences.
50-65: The previous comment about returning an error from the
CurrentBlockfunction instead ofnilis still valid. This would make error handling more explicit.67-82: The previous comment about refactoring the anonymous function in
SubscribeChainHeadEventinto a separate function is still valid. This would make the code easier to test and reason about.120-131: The previous comment about adding a way to stop the goroutine in
IngestNewBlockand handling potential panics is still valid. This would make the code more robust and prevent potential issues.149-153: The previous comment about handling the error returned by
storage.FetchSecret()is still valid. Ignoring errors can lead to unexpected behavior and hard-to-debug issues.go/enclave/nodetype/sequencer.go (8)
53-62: The
sequencerstruct has been updated to replacemempool.Managerwith*txpool.TxPooland addblockchain *ethblockchain.EthBlockchain.

Additional comments: 15
go/enclave/txpool/txpool_test.go (1)
- 91-91: The TODO comment indicates that there is an incomplete test case. It's important to either implement the test case for minting a block and checking the transaction pool or create a task to track this work for future implementation.
go/enclave/txpool/txpool_mock_test.go (1)
- 3-20: The import list is extensive, which is common in Go files, especially for testing. Ensure that all imported packages are used within the file to avoid unnecessary dependencies.
go/enclave/enclave.go (5)
13-17: The addition of the
txpoolimport statement is correct and aligns with the changes described in the summary. This import is necessary for initializing the new transaction pool.130-131: The replacement of the previous
chainConfiginitialization withethblockchain.ChainParamsis a significant change. It is important to ensure that theChainParamsfunction correctly sets up the chain configuration and that all references tochainConfigthroughout the codebase are updated to work with the new configuration structure.200-201: The initialization of
mempoolusingtxpool.NewTxPoolreplaces the previous mempool manager. It is crucial to verify that the new transaction pool is initialized with the correct parameters and that it integrates seamlessly with the rest of the system, especially with theEthBlockchaintype.217-219: The usage of
chainConfigwithout the address-of operator (&) suggests that the function signatures fornodetype.NewSequencerand potentially other functions have been updated to accept a value instead of a pointer. This change should be verified across the codebase to ensure consistency and to prevent potential runtime errors due to type mismatches.251-251: The creation of a new
debuggerinstance is tied to thechainandchainConfig, which indicates that debugging capabilities may have been enhanced or modified to work with the new chain structure. It is important to ensure that the debugger functions as expected and that any new debugging features are documented and tested.go/enclave/nodetype/sequencer.go (8)
9-18: Reorganization of import statements is a common practice to keep the code clean and maintainable. Ensure that all new imports are used and that there are no conflicts with existing code.
28-33: The constant
RollupDelayis introduced. Verify that this constant is being used consistently throughout the codebase and that its value is appropriate for the intended behavior.53-61: The
sequencerstruct has been updated to include ablockchainfield of type*ethblockchain.EthBlockchainand amempoolfield of type*txpool.TxPool. Ensure that these new fields are properly initialized and used wherever necessary.68-83: > Note: This review was outside of the patch, so it was mapped to the patch with the greatest overlap. Original lines [64-81]
The
NewSequencerfunction signature has been updated to include the newblockchainandmempoolparameters. Ensure that all invocations of this function are updated accordingly.
- 143-166: > Note: This review was outside of the patch, so it was mapped to the patch with the greatest overlap. Original lines [138-164]
The
initGenesisfunction has been refactored to include blockchain ingestion and mempool start. Ensure that the error messages are clear and that the blockchain and mempool are correctly initialized and started.
183-207: The
createNewHeadBatchfunction now uses pending transactions from the mempool. Ensure that the transaction selection logic is correct and that the limiter is functioning as expected. Also, verify that the error handling is appropriate and that the transactions are being processed correctly.253-262: The
produceBatchfunction has been modified to include blockchain ingestion. Ensure that the batch is correctly added to the blockchain and that the pending transactions are removed from the mempool as expected.364-366: The
SubmitTransactionfunction has been simplified to directly add the transaction to the mempool. Ensure that the mempool'sAddmethod is robust and handles all necessary validation and error checking.Overall, the changes to
sequencer.goseem to be focused on integrating the newEthBlockchainandTxPooltypes into the sequencer logic. It is important to ensure that these changes are thoroughly tested, especially since they involve critical components like transaction handling and blockchain ingestion. Additionally, ensure that all error messages provide enough context to be useful for debugging and that the new code follows the existing coding standards and practices of the Obscuro network's codebase.

86-89: The test assertion for the transaction count has been updated to expect 5 transactions. Ensure that this change aligns with the intended number of transactions to be issued in the test setup. If the number of transactions issued is dynamic or can vary, consider parameterizing this assertion to avoid brittle tests.
238-251: The nonce is being set outside the loop, which is good for performance. However, the
issuerWallet.GetNonceAndIncrement()method is still being used inside the loop. This could lead to incorrect nonce values if theissuerWalletdoes not internally track the nonce correctly. It's important to ensure that the nonce is being managed correctly to avoid transaction failures due to nonce mismatch.

Does this logic belong in the txpool as well?
There was a problem hiding this comment.
I thought the same thing, but I didn't want to pass the limiter to the tx pool. Do you think the limiter should be in the txpool ? So that we can lazily build the batch ?

how do they do it in geth?

Very similar..! Cycle through each lazy tx, resolve it, and then add it to the block until there's it hits the block gas.

// Check interruption signal and abort building if it's fired.

if env.gasPool.Gas() < params.TxGas {
log.Trace("Not enough gas for further transactions", "have", env.gasPool, "want", params.TxGas)
break
}
// Retrieve the next transaction and abort if all done.

go/enclave/txpool/txpool.go (3)
3-13: The import statements are well-organized and follow the convention of grouping standard library imports separately from third-party packages. This is a good practice for readability and maintainability.
15-22: The
TxPoolstruct is well-defined with clear field names indicating their purpose. However, ensure that therunningfield is accessed in a thread-safe manner ifTxPoolmethods are called concurrently.75-77: The
Runningmethod provides a simple way to check the running status of the pool. Ensure that this method is thread-safe ifTxPoolcan be accessed concurrently.go/enclave/txpool/txpool_test.go (3)
91-91: This TODO comment indicates that there is an intention to extend the test to include block minting and checking the transaction pool's state afterward. It's important to ensure that this test is completed to verify the full lifecycle of a transaction within the pool.
20-92: The test function
TestTxPool_AddTransaction_Pendingis well-structured and covers the initialization of the transaction pool, adding a transaction, and checking its pending status. However, it relies on a sleep function to wait for the transaction to be processed, which is not ideal for test reliability and performance. It would be beneficial to replace this with a more deterministic synchronization mechanism.94-110: The
applyGenesisStatefunction is a new addition that sets up the initial state for the test blockchain. It's important to ensure that this function is called appropriately and that the genesis state is correctly applied to the mock storage. The error handling within this function is done well, with errors being wrapped to provide more context.integration/simulation/simulation.go (1)
- 230-234: The gas limit set here is extremely high (
1025_000_000). This seems like an error, as Ethereum gas limits are typically much lower. Verify that this value is correct and adjust it if necessary. If this is a simulation-specific parameter, consider documenting why such a high value is used.- Gas: 1025_000_000, + Gas: 10_000_000, // Adjusted to a more typical gas limitgo/enclave/enclave.go (6)
10-23: The addition of new imports for
ethchainadapterandtxpoolis appropriate given the context of integrating Ethereum's mempool into the Obscuro network. These imports are necessary for the new functionality being introduced.51-56: The addition of new imports for
debuggerandeventsis consistent with the changes described in the summary, such as the introduction of a newdebugcomponent and the update to thesubscriptionManager.198-202: The creation of
blockchainusingethchainadapter.NewEthChainAdapterand the initialization ofmempoolwithtxpool.NewTxPoolare key changes that align with the pull request's goal of integrating Ethereum's mempool. It is important to ensure that error handling is robust here, as the initialization of these components is critical to the system's operation.212-220: > Note: This review was outside of the patch, so it was mapped to the patch with the greatest overlap. Original lines [204-231]
The conditional initialization of
serviceas either aSequenceror aValidatorbased on theconfig.NodeTypeis a logical change that reflects the system's need to differentiate node behavior. It is important to ensure that all necessary dependencies are correctly passed to the constructors ofSequencerandValidator.
234-239: The initialization of
chainwith theNewChainfunction, passing in thestorage,chainConfig,genesis, andlogger, is a straightforward instantiation that seems to follow the established patterns in the codebase.248-252: The creation of a new
debuggerinstance and its inclusion in theenclaveImplstruct is consistent with the summary's mention of a newdebugcomponent. It is important to ensure that thedebugcomponent is properly configured and that its use is gated by appropriate configuration flags or permissions to prevent unauthorized access.go/enclave/evm/ethchainadapter/eth_chainadapter.go (10)
3-21: The import section is well-organized and follows the convention of grouping standard library imports separately from third-party packages. However, it's important to ensure that all imported packages are used within the file to avoid unnecessary dependencies.
23-30: The
EthChainAdapterstruct is well-defined and encapsulates the necessary components for the adapter's functionality. It's important to ensure that all fields are used effectively within the adapter's methods.32-41: The constructor function
NewEthChainAdapteris correctly returning a pointer to a newEthChainAdapterinstance. It's good practice to ensure that all parameters passed to the constructor are validated before use.43-46: The
Configmethod correctly delegates to theChainParamsfunction to retrieve the chain configuration. It's important to ensure thatChainParamsis robust and handles all possible chain IDs correctly.48-64: The
CurrentBlockmethod retrieves the current head of the chain from the batch registry and storage. Error handling is present, but it logs a warning and returnsnilin case of an error. Consider if this is the desired behavior or if the error should be propagated to the caller.67-81: The
SubscribeChainHeadEventmethod sets up a subscription to chain head events. It's important to ensure that thequitchannel is appropriately handled in all calling contexts to avoid potential goroutine leaks.84-98: The
GetBlockmethod retrieves a specific block by height. Error handling is consistent with theCurrentBlockmethod, logging the error and returningnil. Again, consider if this is the desired behavior or if the error should be propagated.101-118: The
StateAtmethod returns a state database for a given root hash. The method checks for an empty root hash and returnsnilwithout an error. Ensure that this behavior is consistent with the expectations of the callers. Also, thenilnillint exception is used; verify that this is intentional and justified.120-130: The
IngestNewBlockmethod ingests a new block into the adapter. It converts the batch to an Ethereum block and sends a chain head event. The use of a goroutine for sending the event is appropriate, but ensure that thenewHeadChanchannel has sufficient buffer or that the receiver is always ready to prevent blocking the goroutine.133-146: The
NewLegacyPoolConfigfunction creates a default legacy pool configuration. Ensure that the hardcoded values are appropriate for the application's requirements and that they are documented if they deviate from standardgethconfigurations.go/enclave/nodetype/sequencer.go (8)
5-21: Reordering of import statements is generally fine as long as it follows the convention of grouping standard library imports separately from third-party packages. However, it's important to ensure that no imports were removed that are still needed by the code.
28-31: The addition of new imports suggests that new dependencies have been introduced. Verify that these new dependencies are properly managed (e.g., vendored if necessary) and that their licenses are compatible with the project's license.
53-61: The
sequencerstruct has been updated to include new fields such asblockchainandmempool. Ensure that all usages of thesequencerstruct throughout the codebase have been updated to handle these new fields appropriately.95-100: The initialization of the
sequencerstruct within theNewSequencerfunction is correct and follows the Go convention of listing fields explicitly. This is good for readability and maintainability.153-176: > Note: This review was outside of the patch, so it was mapped to the patch with the greatest overlap. Original lines [132-175]
The
createGenesisBatchfunction has been refactored and now includes logic to start the mempool and ingest a new block into the blockchain. Ensure that this logic is correct and that the mempool is indeed supposed to be started at this point in the code. Also, verify that the sleep on line 169 is necessary and that there isn't a more deterministic way to ensure the mempool queuing system is initialized.
193-217: The transaction selection logic in
createNewHeadBatchhas been updated to use a limiter. Ensure that the limiter's behavior is well-tested, especially in edge cases where the batch size is close to the limit. Also, verify that the error handling is correct and that the batch creation process is aborted if an unexpected error occurs.263-273: The logging in
produceBatchis good for monitoring and debugging purposes. Ensure that the log levels are appropriate and that sensitive information is not being logged.372-377: The
SubmitTransactionfunction has been updated to use the newmempoolfield of thesequencerstruct. Ensure that this change is reflected everywhere in the codebase where transactions are submitted to the sequencer.

9-20: The import order has been changed to group Obscuro imports separately from Ethereum imports, which is a common practice for readability and organization. This change is purely stylistic and has no impact on functionality.
52-60: The
sequencerstruct has been updated to include a new fieldblockchainof type*ethchainadapter.EthChainAdapter. This change aligns with the pull request's goal to integrate Geth's mempool functionality. Ensure that all instances and usages of thesequencerstruct are updated to handle this new field.67-80: The
NewSequencerfunction signature has been updated to include new parameters such asrollupProducer,rollupConsumer,rollupCompression, andblockchain. This is a breaking change and all calls to this function must be updated accordingly. Additionally, ensure that the new parameters are properly documented in the function's comments to explain their purpose and usage.110-127: The error handling in
CreateBatchhas been updated to provide more context, which is good for debugging. However, ensure that the error messages are consistent and follow a similar format throughout the codebase.192-216: > Note: This review was outside of the patch, so it was mapped to the patch with the greatest overlap. Original lines [192-233]
The
createNewHeadBatchfunction now includes logic to limit the size of the batch using aBatchSizeLimiter. Ensure that the limiter is correctly configured and that the error handling is robust. The error message on line 209 should be more descriptive to aid in debugging. Consider including additional context such as the transaction details or the current batch size.
262-271: The
produceBatchfunction now adds the batch to the chain after it is produced. Ensure that theIngestNewBlockmethod of theblockchaincorrectly handles the new batch and that any transactions in the batch are properly removed from the mempool. The error message on line 268 should be more descriptive to aid in debugging. Consider including additional context such as the batch number or the transaction details.371-377: The
