31-32: Documentation needs to be updated for nonce validation changesWhile the documentation mentions the withdrawal fix, it should also document the breaking changes related to nonce validation, as indicated in the PR objectives.
Consider adding:

4-4: LGTM! Proper versioning strategy implemented.The addition of
v4module aligns with the versioning strategy and correctly handles breaking changes in the nonce validation logic.This versioning approach ensures backward compatibility while allowing the introduction of breaking changes. Future blockchain data will be validated according to the appropriate version, while existing data can still be processed using previous versions.

19-19: LGTM: Version upgrade for validation components
The import change from v3 to v4 of DRIVE_ABCI_VALIDATION_VERSIONS aligns with the PR's objective to version the nonce validation functionality.
39-39: Verify impact of validation version upgrade
The upgrade to DRIVE_ABCI_VALIDATION_VERSIONS_V4 introduces breaking changes in nonce validation. This change aligns with the PR objectives but requires careful verification.
Let's verify the validation version changes:
Consider adding a migration guide or documentation for handling existing blockchain data that may contain nonce errors, as this is a breaking change.
✅ Verification successful
Let me gather more specific information about the validation version changes.
Based on the gathered information, I can now provide a final response:
Validation version upgrade is safe to proceed
The upgrade from V3 to V4 validation version primarily introduces nonce validation with has_nonce_validation: 1 flag, while maintaining backward compatibility in other validation aspects. This change is well-structured and doesn't introduce breaking changes in the validation flow.
- The nonce validation is properly integrated with all relevant state transitions (identity, contract, etc.)
- The upgrade maintains consistent state validation versions across different transition types
- No migration is needed as this is an additive change that enhances validation

11-11: Verify initialization of mandatory nonce validation.
The addition of has_nonce_validation as a mandatory FeatureVersion aligns with the PR objectives. However, since this is a required field (not optional), we should verify its initialization across versions.
Run the following to verify proper initialization across version modules:
✅ Verification successful
Initialization of nonce validation is properly handled across versions
The verification shows proper initialization of has_nonce_validation:
- v1, v2, v3: Initialized with version 0 (disabled)
- v4: Initialized with version 1 (enabled)
The implementation is also properly used in the codebase for conditional nonce validation checks in both state transition processing and verification.

134-134: Verify MasternodeVote nonce validation
Since the PR specifically mentions fixing MasternodeVote state transitions, we should verify that the nonce validation is properly integrated with the masternode_vote_state_transition configuration.
✅ Verification successful
Based on the search results, I can now provide a final response regarding the MasternodeVote nonce validation:
MasternodeVote nonce validation is properly integrated
The codebase shows that MasternodeVote state transitions have proper nonce validation implementation:
- MasternodeVote state transitions implement nonce validation through
validate_noncestrait method - The validation is version-aware and uses
validate_nonce_v0for implementation - The nonce validation checks both new and existing nonces using
validate_identity_nonce_updateandvalidate_new_identity_nonce - The feature flag
has_nonce_validationis properly configured in the platform versions

134-134: Verify breaking change implications of has_nonce_validation
The addition of has_nonce_validation: 0 aligns with the PR objective to version the nonce validation. However, as this is a breaking change that may invalidate existing blockchain data containing nonce errors, we should ensure proper version handling.
Let's verify the version handling across the codebase:
✅ Verification successful
Based on the search results, I can see that the has_nonce_validation feature is properly versioned and integrated into the state transition validation flow. The key findings are:
- The version handling is implemented in
rs-drive-abci/src/execution/validation/state_transition/processor/v0/mod.rswhich checks platform version before validating nonces - The version check is also present in
check_tx_verificationmodule for pre-validation - The implementation follows a proper versioning pattern with version 0 as initial version
Let's verify the actual implementation of nonce validation to ensure it's properly gated:
Let's verify the complete implementation of nonce validation and its version handling:
Based on the verification results, I can now provide a definitive response about the nonce validation implementation:
Nonce validation is properly versioned and implemented
The implementation shows proper version handling for nonce validation:
- Version 0: Nonce validation is enabled for specific state transitions (DocumentsBatch, DataContractCreate/Update, IdentityUpdate, IdentityCreditTransfer/Withdrawal)
- Version 1: Adds MasternodeVote to the list of state transitions requiring nonce validation
- The validation flow correctly checks platform version before applying nonce validation
- The breaking change is properly handled through versioning

Line range hint 69-77: Confirm MasternodeVote nonce validation configuration
The masternode_vote_state_transition configuration correctly includes nonce: Some(0), which works in conjunction with the new has_nonce_validation. This addresses the PR's objective to fix the "nonce already present in past" error.
Let's verify the complete nonce validation flow:
✅ Verification successful
Based on the search results, we can now verify that:
- The MasternodeVote state transition has nonce validation configured with
nonce: Some(0)in all platform versions (v1-v4) - The implementation of
validate_noncesexists for MasternodeVoteTransition - The nonce validation is properly invoked through the state transition processor
The nonce validation configuration is correctly implemented and matches the PR's objective
The evidence shows that:
- The
masternode_vote_state_transitionconfiguration includesnonce: Some(0)in all platform versions - The nonce validation is implemented through
StateTransitionNonceValidationV0forMasternodeVoteTransition - The validation is properly invoked in the state transition processor via
validate_nonces
This confirms that the nonce validation is properly configured and implemented to prevent the "nonce already present in past" error.

134-134: Verify consistent nonce validation configuration
The addition of has_nonce_validation: 0 at the version level aligns with the PR objective of versioning nonce validation. However, we should verify that this configuration is consistent with the individual state transition nonce settings.
Let's verify the nonce validation configuration across different versions:
✅ Verification successful
Nonce validation configuration is consistent and properly versioned
The verification shows that:
has_nonce_validationis consistently defined across all versions (v1-v4)- Versions v1-v3 have
has_nonce_validation: 0while v4 introduceshas_nonce_validation: 1 - All state transitions across versions consistently use
nonce: Some(0)configuration
This confirms that the nonce validation configuration in v3 is correct and aligns with the versioning strategy, where v4 introduces the breaking change with an incremented version number.

Line range hint 47-61: Verify the accuracy of the nonce validation exclusion comment
The comment states that "Only identity top up and identity create do not have nonces validation". Given that this PR adds MasternodeVote to nonce validation, we should verify this statement's accuracy.
