Summary of Changes
Hello @alpe, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request significantly enhances the go-execution-abci project by integrating a new 'network' module focused on validator attestation and consensus. It establishes a robust local testing environment for inter-blockchain communication (IBC) and network module interactions. Furthermore, it refactors the core block execution adapter to support pluggable components for metrics and block filtering, notably enabling a soft confirmation mechanism based on the new network module's attestations.
Highlights
- New Network Module: A dedicated
networkmodule has been introduced, managing validator attestations, checkpoints, and consensus-related functionalities. It includes its own state management, message handlers, and query services. - Attestation and Checkpoint Logic: The
networkmodule now handlesBeginBlockerandEndBlockerlogic to process checkpoints, calculate voted power, check quorum for soft confirmation, and manage epoch-based validator participation. This includes emitting detailed checkpoint events. - Local Development & Testing Environment: A comprehensive suite of new
hackscripts and configuration files has been added. This enables easy local setup of Gaia and Rollkit chains, establishing IBC connections using Hermes, and testing ICS20 token transfers, along with a Go-based attester client. - Adapter Refactoring for Extensibility: The core
Adapter(executor) has been refactored to accept functional options, allowing for flexible injection of metrics and a newBlockFilterinterface. This improves the modularity and configurability of the system. - Soft Confirmation Integration: A
NetworkSoftConfirmationBlockFilterhas been introduced, enabling the Rollkit node to leverage thenetworkmodule's soft confirmation status. This means blocks can now be queued and only published once they achieve soft confirmation from the attester network, enhancing finality guarantees. - Protobuf Definitions & CLI: New protobuf definitions for the
networkmodule's messages, queries, and types have been added, along with auto-generated CLI commands for interacting with the module, making it accessible via the command line. - Audit Document: A detailed
audit.mdfile is included, outlining current TODOs, incomplete features, and potential security vulnerabilities within the newly introduced network module. This provides a clear roadmap for future development and hardening efforts.

Code Review
This pull request introduces the network module and integrates it into the Rollkit execution adapter. Key changes include adding module logic for validator attestations and epochs, updating build scripts, and adding a test attester client. The review identified several areas for improvement, including critical security vulnerabilities related to signature verification and rate limiting, high correctness issues regarding the use of current validator set data for historical calculations, and various medium-severity issues related to incomplete features, test script practices, and error handling. The hardcoded mnemonics in test scripts are also noted as a security risk.

🧹 Nitpick comments (22)
hack/attester/README.md (1)
1-3: Enhance the README with more detailed usage instructions.The current README is quite brief. Consider adding:
- How to build and run the attester tool
- Required configuration parameters
- Command-line usage examples
- Prerequisites and dependencies
Here's a suggested enhancement:
# Attest everything attester -little helper that pulls new blocks from the rpc node and submits (fake) attestations after each epoch +A helper tool that pulls new blocks from the RPC node and submits (fake) attestations after each epoch. + +## Usage + +```bash +go run main.go [flags] +``` + +## Configuration + +[Add configuration details here] + +## Prerequisites + +[Add prerequisites here]hack/README.md (1)
16-16: Consider using absolute path or documenting directory assumption.The attester command assumes the current directory structure. Consider either using an absolute path or documenting that this command should be run from a specific directory.
hack/download.sh (1)
52-58: Enhance error handling with descriptive messages.The download function should provide more specific error information to help with debugging.
download_file() { local url=$1 local output_path=$2 + local filename=$(basename "$output_path") - echo "Downloading: $url" + echo "Downloading $filename from: $url" curl -L -o "$output_path" "$url" if [ $? -ne 0 ]; then - echo "Failed to download $url" + echo "Error: Failed to download $filename from $url" + echo "Please check your internet connection and verify the URL is accessible" exit 1 fi + echo "Successfully downloaded $filename" }audit.md (3)
6-6: Fix hyphenation in "TODOs".The term should be hyphenated as "TO-DOs" when used as a plural noun.
-## TODOs and Incomplete Features +## TO-DOs and Incomplete Features
14-14: Add missing comma for clarity.The sentence would be clearer with a comma before "but."
- - The `ejectLowParticipants` function is a stub that only logs a message but doesn't actually implement the ejection logic. + - The `ejectLowParticipants` function is a stub that only logs a message, but doesn't actually implement the ejection logic.
57-57: Add missing preposition.The sentence needs "to" before "complete" for proper grammar.
- - Complete all TODO items, particularly the signature verification and validator ejection logic. + - Complete all TO-DO items, particularly the signature verification and validator ejection logic.hack/ibc-connection-hermes.sh (1)
14-15: Remove unused variables or document their purpose.The
GAIA_DENOMandWORDLED_DENOMvariables are defined but not used in the script. Consider removing them or adding a comment explaining if they're reserved for future use.-GAIA_DENOM="stake" -WORDLED_DENOM="stake"hack/init-gaia.sh (1)
82-82: Consider backgrounding and process management best practices.The current approach of starting the process in background and waiting for it could be improved with better process management. Consider using a process manager or at least capturing the exit status properly.
-"$GAIAD_BIN" start --home "$GAIA_HOME" --minimum-gas-prices "0stake" --rpc.laddr tcp://0.0.0.0:26654 --rpc.pprof_laddr localhost:6061 --p2p.laddr tcp://0.0.0.0:26653 --grpc.address 0.0.0.0:9091 | tee "$GAIA_HOME/gaia.log" & +"$GAIAD_BIN" start --home "$GAIA_HOME" --minimum-gas-prices "0stake" --rpc.laddr tcp://0.0.0.0:26654 --rpc.pprof_laddr localhost:6061 --p2p.laddr tcp://0.0.0.0:26653 --grpc.address 0.0.0.0:9091 2>&1 | tee "$GAIA_HOME/gaia.log" &modules/network/client/cli/query.go (3)
76-79: Improve error message consistency.The error formatting could be more consistent with other commands. Consider using a consistent error message format across all commands.
- return fmt.Errorf("invalid height: %w", err) + return fmt.Errorf("invalid height %q: %w", args[0], err)
111-114: Improve error message consistency.Similar to the height parsing, the epoch parsing error message could include the invalid value for better debugging.
- return fmt.Errorf("invalid epoch: %w", err) + return fmt.Errorf("invalid epoch %q: %w", args[0], err)
176-179: Improve error message consistency.Consistent with other commands, include the invalid value in the error message.
- return fmt.Errorf("invalid height: %w", err) + return fmt.Errorf("invalid height %q: %w", args[0], err)modules/network/types/keys.go (1)
24-34: Consider addressing the TODO comment about key optimization.The TODO comment suggests using numbers instead of verbose keys. This could improve storage efficiency and performance.
// todo (Alex): use numbers instaed of verbose keyse?The typo "instaed" should be "instead" and "keyse" should be "keys". Would you like me to propose a refactored version using numeric prefixes?
modules/network/keeper/bitmap.go (1)
89-99: Consider optimizing CountInRange for better performance.The current implementation iterates bit by bit, which could be inefficient for large ranges. Consider implementing byte-level operations for better performance.
func (bh *BitmapHelper) CountInRange(bitmap []byte, start, end int) int { + if start >= end || start < 0 { + return 0 + } + + maxBits := len(bitmap) * 8 + if end > maxBits { + end = maxBits + } + count := 0 - for i := start; i < end && i < len(bitmap)*8; i++ { + for i := start; i < end; i++ { if bh.IsSet(bitmap, i) { count++ } } return count }hack/run_gmd.sh (1)
117-118: Make DA port configurable.The DA port is hardcoded to 7980, which could cause conflicts in different environments.
-DA_PORT=7980 +DA_PORT="${DA_PORT:-7980}"modules/network/types/msgs.go (1)
64-66: Consider adding size validation for vote field.The vote field is validated for emptiness but not for maximum size, which could lead to DoS attacks with extremely large votes.
if len(msg.Vote) == 0 { return errors.Wrap(sdkerrors.ErrInvalidRequest, "vote cannot be empty") } + +const maxVoteSize = 1024 // Adjust based on your requirements +if len(msg.Vote) > maxVoteSize { + return errors.Wrapf(sdkerrors.ErrInvalidRequest, "vote size exceeds maximum of %d bytes", maxVoteSize) +}modules/network/keeper/msg_server_test.go (1)
86-104: Remove or fix the commented test case.This commented test case should either be removed or properly implemented. If error injection is needed for testing, consider using a proper mocking approach.
Either remove the commented code or implement it properly:
-//{ -// name: "failed to set attester set member", -// setup: func(t *testing.T, ctx sdk.Context, keeper *Keeper, sk *MockStakingKeeper) { -// validatorAddr := sdk.ValAddress([]byte("validator5")) -// validator := stakingtypes.Validator{ -// OperatorAddress: validatorAddr.String(), -// Status: stakingtypes.Bonded, -// } -// err := sk.SetValidator(ctx, validator) -// require.NoError(t, err, "failed to set validator") -// keeper.forceError = true -// }, -// msg: &types.MsgJoinAttesterSet{ -// Validator: "validator5", -// }, -// expErr: sdkerrors.ErrInternal, -// expectResponse: false, -//},modules/network/types/params.go (2)
21-21: Consider documenting the rationale for default epoch length.The TODO asks about a good default epoch length. Consider factors like:
- Expected block time
- Desired checkpoint frequency
- Network latency for attestations
-DefaultEpochLength = uint64(10) // todo (Alex): what is a good default? +// DefaultEpochLength of 10 blocks provides checkpoints every ~10-60 seconds +// depending on block time, balancing finality speed with attestation overhead +DefaultEpochLength = uint64(10)
172-178: Improve SignMode validation robustness.The current validation assumes enum values are sequential, which is fragile.
if v == SignMode_SIGN_MODE_UNSPECIFIED { return fmt.Errorf("sign mode cannot be unspecified") } -if v < SignMode_SIGN_MODE_CHECKPOINT || v > SignMode_SIGN_MODE_IBC_ONLY { - return fmt.Errorf("invalid sign mode: %d", v) +switch v { +case SignMode_SIGN_MODE_CHECKPOINT, SignMode_SIGN_MODE_IBC_ONLY: + return nil +default: + return fmt.Errorf("invalid sign mode: %d", v) } - -return nilmodules/proto/rollkitsdk/network/v1/query.proto (4)
9-9: Remove unused pagination import
cosmos/base/query/v1beta1/pagination.protois imported but no RPC methods utilize pagination. Drop this import unless you plan to add paginated queries.
40-47: Confirm Params response structure
QueryParamsResponsereturns aParamsmessage. EnsureParamsis well-documented intypes.protoand won't grow unexpectedly—consider pagination or selective fields if it does.
49-56: Annotate required fields
Consider adding gRPC field behavior annotations (e.g.,(google.api.field_behavior) = REQUIRED) to clarify thatheightinQueryAttestationBitmapRequestmust be set.
90-95: Normalize quorum fraction representation
quorum_fractionis a string. For consistency with other modules, consider using auint32orsdk.Deccodec rather than arbitrary strings, unless formatting requirements dictate otherwise.

modules/proto/rollkitsdk/network/v1/types.proto (5)
12-30: Well-designed module parameters.The Params message includes comprehensive configuration options for attestation windows, quorum requirements, participation thresholds, pruning, emergency mode, and signing behavior. The use of cosmos.Dec scalars for fractions is appropriate.
32-45: Clear and comprehensive SignMode enum.The SignMode enum provides good flexibility for different validator signing requirements with clear semantics for each mode.
47-63: Well-structured AttestationBitmap message.The AttestationBitmap captures all necessary checkpoint metadata including voting power tracking and soft confirmation status.
65-75: Efficient ValidatorIndex design.The ValidatorIndex provides an efficient mapping for bitmap operations with cached voting power for performance.
7-7: Verify gogoproto import necessity.The static analysis tool reports that
gogoproto/gogo.protodoesn't exist, but it's not currently used in this file. Consider removing this import if it's not needed.#!/bin/bash # Check if gogoproto annotations are used in this file grep -n "gogoproto\." modules/proto/rollkitsdk/network/v1/types.proto || echo "No gogoproto annotations found"modules/network/depinject.go (3)
17-21: Proper interface assertions.The AppModule type properly asserts required interfaces for Cosmos SDK integration.
29-38: Comprehensive ModuleInputs structure.The ModuleInputs includes all necessary dependencies for the network module including keepers and configuration.
47-68: Well-implemented ProvideModule function.The function properly handles authority configuration with appropriate fallback to governance module and constructs the keeper and module correctly.
modules/network/module.go (4)
20-27: Comprehensive interface assertions.The module properly implements all required Cosmos SDK interfaces for full functionality.
86-96: Standard genesis handling pattern.The genesis initialization and export methods follow the standard Cosmos SDK pattern with appropriate error handling.
101-105: Proper service registration.The RegisterServices method correctly registers both message and query servers for the module.
107-113: Correct lifecycle hook implementation.The BeginBlock and EndBlock methods properly delegate to keeper methods with correct context unwrapping.
modules/network/client/cli/query.go (1)
1-34: Well-structured CLI query module with comprehensive command coverage.The implementation follows Cosmos SDK conventions and provides a complete set of query commands for the network module. The command structure is consistent and includes proper error handling.
modules/network/types/keys.go (1)
36-72: Key construction functions are well-implemented.The key construction functions properly use big-endian encoding for numeric values and handle string addresses correctly. The implementation ensures consistent key formatting across the module.
modules/proto/rollkitsdk/network/v1/tx.proto (2)
29-88: Message definitions follow Cosmos SDK conventions correctly.The message definitions are well-structured with proper:
- Signer annotations for message validation
- Scalar type annotations for address fields
- Consistent gogoproto options
- Appropriate field naming and types
7-7: Address the missing import issue.The static analysis tool indicates that the import
cosmos/msg/v1/msg.protodoes not exist. This could cause compilation issues.#!/bin/bash # Verify if the cosmos/msg/v1/msg.proto import exists in the dependency fd -t f "msg.proto" | grep -E "cosmos/msg/v1/msg\.proto|msg\.proto"If the import path is incorrect, it may need to be updated to match the actual path in the Cosmos SDK dependencies.
pkg/adapter/options.go (2)
13-38: Functional options pattern implemented correctly.The functional options pattern is well-implemented with clear separation of concerns. The
WithNetworkSoftConfirmationBlockFilterproperly initializes the filter with required dependencies.
47-84: Robust implementation with proper error handling.The
IsPublishablemethod includes comprehensive error handling and logging. The height validation (minimum of 2) and ABCI query integration are properly implemented.modules/network/keeper/bitmap.go (5)
7-19: Bitmap creation and initialization are well-implemented.The bitmap size calculation correctly handles the byte alignment for any number of validators, and the initialization pattern is standard.
22-29: Proper bounds checking and bit manipulation.The
SetBitmethod includes appropriate bounds checking and uses correct bit manipulation operations. The implementation is safe and efficient.
31-39: Consistent bounds checking in IsSet.The bounds checking logic matches the
SetBitmethod, ensuring consistency across the API.
41-48: Efficient population count implementation.Using
bits.OnesCount8is the optimal approach for counting set bits, providing better performance than manual bit counting.
50-70: Bitwise operations properly handle different bitmap sizes.Both
ORandANDoperations correctly handle bitmaps of different sizes by using the minimum length, preventing buffer overruns.modules/network/types/msgs.go (1)
40-44: The initial pattern didn’t yield any results—let’s broaden our search to list everyGetSignersimplementation and inspect their error handling and address‐conversion logic:#!/bin/bash # 1. List all GetSigners definitions with context rg -C3 "func .*GetSigners" --type go # 2. Extract full bodies of all GetSigners methods ast-grep --pattern $'func ($_) GetSigners() []sdk.AccAddress { $$$ }' # 3. Highlight any panic calls across the repo rg -n "panic(" --type go # 4.

Show all sdk.AccAddressFromBech32 usage rg -C3 "AccAddressFromBech32" --type gomodules/proto/rollkitsdk/network/v1/query.proto (3)
12-38: Validate HTTP REST endpoint paths
The HTTP bindings use/rollkit/network/v1/.... Confirm that the prefix (rollkit) and path segments align with your module route and API conventions (e.g., notrollkitsdk). Also verify path parameters ({height},{epoch},{address}) match the request message fields.
65-72: Reviewparticipation_bitmaptype
participation_bitmapis declared asbytes. If it represents a bitset or repeated boolean, evaluate using a custom repeated field or a typed message for clearer semantics.
80-82: VerifyValidatorIndeximport
TheValidatorIndextype is referenced here. Confirm it’s defined intypes.protoand the import path is correct so code generators can locate it.

225-234: CalculateVotedPower uses current validator powers for historical heights.This function retrieves power from the current validator set when calculating voted power for any height, which will produce incorrect results for historical blocks.
237-244: GetTotalPower returns current total power instead of historical.This function always returns the current total staking power, which is incorrect when checking quorum for historical heights.
258-273: IsSoftConfirmed incorrectly uses current validator set for historical blocks.This function relies on CalculateVotedPower and GetTotalPower which use the current validator set, leading to incorrect soft confirmation status for historical heights.
305-306: Complete the TODO: Prune signatures for pruned heights.Failing to prune signatures will lead to unbounded state growth over time.
Do you want me to generate the implementation for pruning signatures or open a new issue to track this task?

Start the sentence with a capital letter and end with a period.-little helper that pulls new blocks from the rpc node and submits (fake) attestations after each epoch +Little helper that pulls new blocks from the RPC node and submits (fake) attestations after each epoch.Makefile (1)
79-79: Add an 'all' phony target.
checkmakewarns about a missingalltarget. It’s conventional to define:all: test .PHONY: allto provide a sensible default build step.
README.md (1)
90-91: Illustrate soft confirmation block filter usage.The example adds
nilfor metrics but doesn’t show how to enable the network soft-confirmation filter. Consider updating this snippet to passadapter.WithNetworkSoftConfirmationBlockFilter()(or similar) so users see how it hooks into the new--rollkit.network.soft-confirmationflag.hack/README.md (2)
7-10: Add download step for required binaries.Prerequisites mention
download.sh, but no instruction invokes it. Insert:./hack/download.shbefore
./init-gaia.shto fetchgaiad,hermes, and other tools.
13-19: Clarify script execution context.The
run_node.sh,attester, and IBC scripts assume specific working directories and binary locations. Note whether these commands should be run from the repo root and update paths or flags accordingly to avoid confusion.modules/network/genesis.go (1)
35-38: Redundant storage operation.The attestation bitmap is being stored twice - once via
SetAttestationBitmapand once viaStoredAttestationInfo.Set. This could lead to inconsistency if one operation fails.Consider consolidating the storage operations or ensuring atomicity:
- if err := k.SetAttestationBitmap(ctx, ab.Height, ab.Bitmap); err != nil { - return err - } - // Store full attestation info using collections API - if err := k.StoredAttestationInfo.Set(ctx, ab.Height, ab); err != nil { - return err - } + // Store full attestation info using collections API (this should handle bitmap storage internally) + if err := k.StoredAttestationInfo.Set(ctx, ab.Height, ab); err != nil { + return err + }hack/init-gaia.sh (1)
87-89: Improve connection check with timeout.The current connection check could hang indefinitely if the service never becomes available.
-while ! nc -z localhost 26654; do - sleep 1 -done +timeout=60 +counter=0 +while ! nc -z localhost 26654; do + if [ $counter -ge $timeout ]; then + log "31" "❌" "Timeout waiting for Gaia to start" + exit 1 + fi + sleep 1 + ((counter++)) +donehack/ibc-connection-hermes.sh (1)
14-15: Remove unused variables.The variables
GAIA_DENOMandWORDLED_DENOMare defined but never used in the script.-GAIA_DENOM="stake" -WORDLED_DENOM="stake"modules/network/keeper/bitmap.go (3)
50-59: Consider documenting the behavior when bitmaps have different sizes.The OR operation uses the minimum length of the two bitmaps, which means bits beyond
minLenin the destination bitmap remain unchanged. This behavior should be documented to clarify expectations.-// OR performs bitwise OR of two bitmaps +// OR performs bitwise OR of two bitmaps +// Only processes up to the minimum length of the two bitmaps func (bh *BitmapHelper) OR(dst, src []byte) {
61-70: Consider documenting the behavior when bitmaps have different sizes.Similar to the OR method, the AND operation should document that it only processes up to the minimum length, and bits beyond that remain unchanged in the destination.
-// AND performs bitwise AND of two bitmaps +// AND performs bitwise AND of two bitmaps +// Only processes up to the minimum length of the two bitmaps func (bh *BitmapHelper) AND(dst, src []byte) {
89-98: Optimize the CountInRange method for better performance.The current implementation calls
IsSetfor each bit, which repeats the boundary check and bit extraction logic. This could be optimized by working directly with bytes when possible.func (bh *BitmapHelper) CountInRange(bitmap []byte, start, end int) int { + if start >= end || start < 0 { + return 0 + } + maxBits := len(bitmap) * 8 + if end > maxBits { + end = maxBits + } + count := 0 - for i := start; i < end && i < len(bitmap)*8; i++ { - if bh.IsSet(bitmap, i) { - count++ - } + for i := start; i < end; i++ { + byteIndex := i / 8 + bitIndex := uint(i % 8) + if (bitmap[byteIndex] & (1 << bitIndex)) != 0 { + count++ + } } return count }modules/network/keeper/msg_server_test.go (3)
86-104: Remove or complete the commented test case.The commented test case suggests there was an attempt to test error injection but was left incomplete. Either complete this test case or remove it to keep the code clean.
- //{ - // name: "failed to set attester set member", - // setup: func(t *testing.T, ctx sdk.Context, keeper *Keeper, sk *MockStakingKeeper) { - // validatorAddr := sdk.ValAddress([]byte("validator5")) - // validator := stakingtypes.Validator{ - // OperatorAddress: validatorAddr.String(), - // Status: stakingtypes.Bonded, - // } - // err := sk.SetValidator(ctx, validator) - // require.NoError(t, err, "failed to set validator") - // keeper.forceError = true - // }, - // msg: &types.MsgJoinAttesterSet{ - // Validator: "validator5", - // }, - // expErr: sdkerrors.ErrInternal, - // expectResponse: false, - //},
156-160: Add error handling for the SetValidator method.The
SetValidatormethod in the mock should probably never return an error in this implementation, but it's good practice to at least document this or add a comment explaining why errors are not expected.func (m *MockStakingKeeper) SetValidator(ctx context.Context, validator stakingtypes.Validator) error { m.activeSet[validator.GetOperator()] = validator + // Mock implementation - errors not expected in test scenarios return nil - }
175-182: Improve the GetLastValidators mock implementation.The current implementation only returns bonded validators, but the logic could be more explicit about what "last validators" means in this context. Consider adding a comment or making the logic more explicit.
func (m MockStakingKeeper) GetLastValidators(ctx context.Context) (validators []stakingtypes.Validator, err error) { + // Return all bonded validators as "last validators" for _, validator := range m.activeSet { - if validator.IsBonded() { // Assuming IsBonded() identifies if a validator is in the last validators + if validator.IsBonded() { validators = append(validators, validator) } } return }pkg/adapter/options.go (2)
47-51: Clarify the minimum height requirement.The code checks
height < 2but doesn't document why blocks below height 2 are not publishable. Consider adding a comment explaining this business logic.func (f *NetworkSoftConfirmationBlockFilter) IsPublishable(ctx context.Context, height int64) bool { - // First check if height is valid + // Genesis block (height 1) and earlier are not publishable if height < 2 { return false }
56-59: Handle marshaling errors more explicitly.The current error handling silently returns
falseon marshaling errors. Consider logging the error for debugging purposes.reqData, err := req.Marshal() if err != nil { + f.logger.Error("marshal soft confirmation request", "height", height, "error", err) return false }modules/network/types/params.go (1)
21-21: Address TODO: Determine appropriate default epoch lengthThe TODO comment indicates uncertainty about the default epoch length value. Consider factors such as block time, network latency, and desired checkpoint frequency when determining this value.
Would you like me to help analyze appropriate epoch length values based on your network requirements, or open an issue to track this decision?
modules/network/types/keys.go (1)
25-25: Consider the trade-offs of numeric vs verbose keysUsing numeric prefixes would save storage space but reduce debuggability. Consider keeping verbose keys for better maintainability unless storage optimization is critical.
modules/network/keeper/abci.go (1)
135-137: Decide on epoch quorum failure handlingThe TODO questions whether to fail when no checkpoints achieve quorum. This is a critical consensus decision that affects network liveness.
Consider the trade-offs:
- Failing could halt the network if validators are offline
- Logging only could allow the network to continue but without proper attestation
Based on your network's security requirements, you should either return an error or emit a critical event that monitoring systems can alert on.
modules/network/keeper/msg_server.go (1)
27-111: Consider adding metrics for attestation processing.While the implementation handles attestation logic correctly, adding metrics for successful/failed attestations would help with monitoring and debugging in production.
hack/attester/main.go (2)
256-256: Consider making the block hash configurable or properly computed.Using a hardcoded "0x00" block hash in attestations, even for testing, could lead to confusion or issues if this utility is used in more realistic test scenarios.
Consider adding a flag to specify the block hash or computing it from actual block data.
259-261: Remove commented-out code.The commented-out error handling code should be either removed or properly implemented.
- //time.Sleep(time.Second / 10) - //continue - return err + return errmodules/network/keeper/keeper.go (1)
65-71: Remove commented schema building code.The commented code for explicit schema building appears to be unnecessary. Consider removing it to improve code clarity.
Apply this diff:
- // The schema is built implicitly when the first collection is created or can be explicitly built. - // schema, err := sb.Build() - // if err != nil { - // panic(err) - // } - // keeper.schema = schema -

hack/.gitignore (1)
1-3: Add .gitignore entries for hack directory. The patterns correctly exclude generated artifacts fromdownloads/,testnet/, andconfig/.go.mod (1)
42-42: Verify direct protobuf dependency. Movinggoogle.golang.org/protobuffrom indirect to direct is appropriate given new protobuf-generated code in the network module. Ensure the versionv1.36.6is compatible with other indirect dependencies (e.g.,genprotoandgocosmos).pkg/adapter/adapter_test.go (1)
84-84: Adapter constructor updated correctly. The test now matches the new variadic options signature forNewABCIExecutor, removing theNopMetrics()argument. All required dependencies are passed.server/flags.go (2)
9-9: Add new CLI flag constant: good.The constant
FlagNetworkSoftConfirmationis clearly defined and follows the existing naming convention.
19-19: Verify flag binding and config support.The flag is added via
cmd.Flags().Bool, but there’s no pointer binding toconfig.DefaultConfig. Please confirm that a correspondingNetworkSoftConfirmationfield exists in your config struct and that the flag’s value is properly loaded (e.g., via Viper or aBoolVar) so the block filter option can use it.Makefile (1)
75-76: Add proto-gen moves for network module: good.The new
mvcommands correctly relocate the generated network protobuf files. Make sure the source directories exist post-buf generateto avoid silent failures.README.md (1)
25-25: Clean up Mermaid diagram whitespace: good.Minor whitespace adjustments improve readability without affecting functionality.
modules/network/types/genesis.go (2)
7-14: LGTM! Genesis state initialization follows best practices.The
DefaultGenesisStatefunction correctly initializes the genesis state with default parameters and empty slices for validator indices and attestation bitmaps, which is appropriate for a clean module start.
16-48: Comprehensive validation logic with good error handling.The validation method thoroughly checks:
- Parameter validation through delegation
- Duplicate validator addresses and indices detection using maps
- Attestation bitmap integrity (positive heights and power constraints)
The error messages are descriptive and will help with debugging genesis state issues.
server/start.go (2)
358-366: Good refactoring to options pattern for extensibility.The change from passing individual parameters to building a slice of options makes the executor configuration more flexible and follows good design patterns. The conditional Prometheus metrics setup is correct.
364-366: Verify flag definition and adapter option implementation.The code references
FlagNetworkSoftConfirmationandadapter.WithNetworkSoftConfirmationBlockFilter(), but these aren't defined in this file. Ensure these are properly defined in their respective locations.#!/bin/bash # Description: Verify the flag definition and adapter option implementation # Expected: Find definitions of FlagNetworkSoftConfirmation and WithNetworkSoftConfirmationBlockFilter echo "Searching for FlagNetworkSoftConfirmation definition:" rg -A 2 "FlagNetworkSoftConfirmation.*=" echo -e "\nSearching for WithNetworkSoftConfirmationBlockFilter implementation:" rg -A 5 "func.*WithNetworkSoftConfirmationBlockFilter"modules/proto/rollkitsdk/network/v1/genesis.proto (2)
10-20: Standard genesis state proto definition with proper field annotations.The
GenesisStatemessage definition follows Cosmos SDK conventions with appropriate gogoproto annotations for nullable fields. The field structure aligns with the Go implementation ingenesis.go.
7-7: Verify gogoproto import path and availability.Static analysis indicates the gogoproto import may not be found. This could be a build environment issue or incorrect import path.

10-21: Architecture detection logic is correct but could be more robust.The architecture mapping from
uname -moutput to expected labels is handled well with appropriate error handling for unsupported architectures.modules/network/types/codec.go (3)
10-16: Standard amino codec registration following Cosmos SDK patterns.The legacy amino codec registration correctly registers all message types with appropriate type URLs. The naming convention follows the
module/MessageTypepattern.
18-28: Proper protobuf interface registration with gRPC service integration.The interface registry correctly registers all message types as
sdk.Msgimplementations and includes the gRPC service descriptor registration, which is essential for proper message routing.
35-38: Appropriate codec initialization and sealing.The init function properly registers types with the amino codec and seals it to prevent further modifications, which is the recommended pattern for Cosmos SDK modules.
modules/proto/rollkitsdk/network/v1/types.proto (2)
7-7: Static analysis false positive - gogoproto import is valid.The static analysis tool is flagging the gogoproto import as missing, but this is a false positive. The
gogoproto/gogo.protoimport is a standard protobuf extension used extensively in Cosmos SDK projects for Go-specific annotations.
12-75: Well-structured protobuf schema with appropriate field design.The message definitions follow protobuf best practices with:
- Sequential field numbering
- Appropriate scalar types for cosmos addresses and decimals
- Clear field names and documentation
- Proper enum value assignment starting from 0
modules/network/autocli.go (1)
10-79: Comprehensive and well-structured AutoCLI configuration.The AutoCLI configuration properly maps all query and transaction commands to their respective protobuf services with:
- Clear usage strings and descriptions
- Appropriate positional arguments matching protobuf fields
- Complete coverage of the network module's RPC methods
modules/network/types/expected_keepers.go (1)
11-27: Clean and minimal keeper interfaces following good design principles.The expected keeper interfaces are well-designed with:
- Minimal surface area exposing only required methods
- Proper use of context.Context for cancellation
- Appropriate SDK types for parameters and return values
- Good abstraction for dependency injection
modules/network/client/cli/tx.go (3)
17-33: LGTM: Well-structured root command.The root transaction command follows Cosmos SDK conventions properly with appropriate subcommands and validation.
74-98: LGTM: Join attester command is well implemented.The command correctly derives the validator address and follows proper validation patterns.
101-126: LGTM: Leave attester command is well implemented.The command structure is consistent with the join command and properly implemented.
hack/ibc-connection-hermes.sh (1)
122-127: LGTM: IBC channel creation is properly configured.The channel creation command correctly sets up the transfer port with automatic client and connection creation.
hack/ics20-token-transfer.sh (2)

49-60: Well-designed BlockFilter interface.The
BlockFilterinterface provides a clean abstraction for controlling block commit event publishing. The functional implementation withBlockFilterFnfollows good Go patterns for simple function-based implementations.
88-91: Good encapsulation improvements.Changing
Metricsto an unexportedmetricsfield improves encapsulation. The addition ofblockFilterandstackedEventsfields properly supports the new event stacking functionality.
104-105: Options pattern implementation looks good.The constructor now uses functional options, which is a clean and extensible design pattern. The default values are appropriately set with
NopMetrics()and a pass-throughBlockFilterFn.Also applies to: 123-129
369-372: Useful transaction hash logging for debugging.Adding SHA256 hash logging for processed transactions will be valuable for debugging and tracing transaction execution.
478-486: Block filtering logic correctly implemented.The implementation properly checks
blockFilter.IsPublishable()to decide whether to fire events immediately or stack them. ClearingfbResp.Eventswhen stacking prevents premature storage, which is the correct behavior.
67-67: Excellent error wrapping improvements.The consistent addition of error wrapping with
fmt.Errorfand%wverb provides better error context throughout the adapter, which will significantly improve debugging and error tracing.Also applies to: 262-262, 275-275, 293-293, 317-317, 327-327, 332-332, 420-420, 488-488, 507-507, 513-513, 521-521, 530-530, 542-542, 549-549, 560-560, 645-645, 714-714, 718-718, 722-722

69-69: Replace placeholder commit hash with actual implementation.This has been identified in previous reviews - the commit hash should use actual block/commit data instead of a placeholder.

16-24: LGTM! Clean validation logic.The BeginBlocker correctly enforces the checkpoint-only sign mode constraint with appropriate error handling.
26-49: LGTM! Well-structured end block logic.The EndBlocker properly handles both checkpoint and epoch processing with clear separation of concerns and good error handling.
67-67: Verify the validator hash calculation approach.The validator hash is computed from the attestation bitmap bytes, but this may not represent the actual validator set. Consider whether this should hash the validator set data instead of the bitmap.
Could you clarify if hashing the bitmap bytes is the intended approach for the validator hash, or should this be computed from the actual validator set?

617-637: Address event persistence for restart recovery.The stacked events are stored in memory and will be lost on node restart, potentially causing missed event publications. This aligns with the existing TODO comment.
The
StackedEventstruct design is appropriate for holding all necessary event data for deferred publishing.
707-713: Fix incomplete context cancellation handling.The context cancellation check modifies
maxPosReleasedbut continues processing, which could lead to partial event publishing and inconsistent state.Apply this fix to return early on context cancellation:
- // todo (Alex): exit loop when ctx cancelled - select { - case <-ctx.Done(): - maxPosReleased = i - break outerLoop - default: - } + select { + case <-ctx.Done(): + // Store remaining events for later processing + a.stackedEvents = a.stackedEvents[i:] + return ctx.Err() + default: + }

369-373: Consider making transaction hash logging configurable.The SHA256 hash logging for each transaction could be very verbose in production environments with high transaction throughput. Consider using a configurable log level or feature flag.
- for i, tx := range txs { - sum256 := sha256.Sum256(tx) - a.Logger.Debug("Processed TX", "hash", strings.ToUpper(hex.EncodeToString(sum256[:])), "result", fbResp.TxResults[i].Code, "log", fbResp.TxResults[i].Log, "height", blockHeight) - } + if a.Logger.Core().Enabled(log.LevelDebug) { + for i, tx := range txs { + sum256 := sha256.Sum256(tx) + a.Logger.Debug("Processed TX", "hash", strings.ToUpper(hex.EncodeToString(sum256[:])), "result", fbResp.TxResults[i].Code, "log", fbResp.TxResults[i].Log, "height", blockHeight) + } + }
691-733: Well-designed soft confirmation mechanism with room for improvement.The
publishQueuedBlockEventsmethod implements a sophisticated soft confirmation system that correctly processes stacked events. The approach of updating stored block responses before firing events maintains consistency with CometBFT behavior.However, consider these improvements:
- Add comprehensive logging for debugging complex event processing scenarios
- Implement metrics to track stacked event counts and processing times
- Consider adding configurable timeouts for event processing
