PROFILE
Oliviasaa
Over ten months, contributed to the iotaledger/iota repository by designing and implementing core consensus, scoring, and misbehavior tracking systems for blockchain governance. Leveraging Rust and Move, developed features such as a centralized Scorer component, persistent misbehavior metrics with Prometheus integration, and epoch-aware reward modulation. Refactored consensus logic for clarity and reliability, introduced protocol-level feature flags for configurability, and enhanced error handling across modules. Improved validator observability and network efficiency by rate-limiting misbehavior reports and decoupling scoring responsibilities. Ensured robust test coverage, cross-crate compatibility, and durable metrics storage, enabling scalable, auditable, and resilient blockchain infrastructure for validators and operators.

May 1, 2026May 2026 delivered a stable, scalable misbehavior scoring pipeline with storage-backed metrics and clearer architectural boundaries across crates. Implemented the Misbehavior Scoring Metrics System by refactoring the Scorer module to Vec-based data models, decoupling responsibilities into MisbehaviorMonitor, ReportAggregator, and Scorer, and exposing metrics to iota-core via ConsensusOutputAPI. Introduced MisbehaviorConfig as the single source of truth for misbehavior categories and migrated scoring metrics types into consensus/iota-core with Starfish-compatible naming. Added a storage-backed ScoringMetricsStore with per-authority counters and Prometheus-style observability; extended storage layer (mem_store/rocksdb_store) to persist scoring updates atomically and integrated with DagState write batches. Fortified tests (unit/integration), lint, and compilation to ensure a solid baseline. This work improves scalability, reliability, and observability, enabling durable metrics and faster issue detection for operators and developers.

Apr 1, 2026April 2026 monthly summary for iotaledger/iota focused on delivering a high-value feature to improve consensus efficiency and network reliability. Key feature delivered: Consensus Misbehavior Report Rate Limiting. Implemented a rate-limiting mechanism for misbehavior reports in the consensus module to reduce unnecessary network traffic and improve efficiency. The change includes: (a) adding last-submitted report information (sequence number and summary) to the Scorer, (b) enforcing rate limits based on: metrics changed since last report, at least 1000 checkpoints elapsed since the last report, and the current checkpoint within 100 behind the highest verified checkpoint, and (c) forcing a report when the epoch nears its end (checkpoint_timestamp >= next_reconfiguration_timestamp_ms - 2000) to ensure inclusion before epoch close. The work was co-authored by Piotr Macek. The commit implementing this feature is e318f45fd463a8fef2dac932695116bdaef7625b. It includes tests (basic linting, compilation, and unit/integration tests) with the note that patch-specific tests were not added, though existing unit tests pass locally.

Feb 1, 2026February 2026 monthly summary for iotaledger/iota. Delivered a protocol-level feature flag to decouple validator score calculation from epoch advancement (pass_calculated_validator_scores_to_advance_epoch, protocol v20). This enables safer epoch transitions and greater configurability, with Devnet-focused rollout. Implemented gating: when the flag is disabled, a default MAX_SCORE is passed to advance_epoch; when enabled, locally calculated scores are forwarded. Comprehensive validation included linting, compilation, formatting, and unit/integration tests. Release notes updated to reflect the feature flag and Devnet-only usage, aligning with ongoing protocol configurability.

Dec 1, 2025December 2025 monthly summary for iotaledger/iota. Focused on delivering governance and protocol robustness enhancements, with strong test coverage and cross-library compatibility. Key business outcomes: improved misbehavior detection, more granular validator reward modulation, and ensured downstream compatibility for indexers and tooling. Key achievements: - Misbehavior Reporting in Consensus System: Implemented the MisbehaviorReport consensus message creation and submission pathway, updating transaction handling and consensus message structures. Associated commit: b910a68a3d8751cd947d5b1146028c9d74e42168. Tests and linting/formatting completed; protocol-level changes enable detection and dissemination of misbehavior across the committee. - Epoch Reward Scoring via v4 Advance Epoch Transaction: Introduced version 4 of the advance epoch transaction to modulate rewards based on validator scores while preserving existing validator reporting. Updated iota-framework with a new advance epoch function and added a ChangeEpochV4 system transaction for compatible networks with score_based_rewards. Associated commit: 960a93f760b8ed8b9db68c6df6f3942fab01dc26. Tests added and pass; downstream consumers (iota_data_ingestion_core) require a dependency bump for full compatibility. Major bugs fixed: - No explicit bug fixes documented in this period; primary focus on feature delivery with comprehensive test coverage and quality checks (linting, compilation, unit/integration tests passed). Overall impact and accomplishments: - Strengthened protocol integrity and governance with misbehavior reporting and score-based rewards, enabling more reliable consensus and incentive alignment. - Preserved compatibility with existing systems while expanding capabilities; prepared downstream ecosystems for dependency changes to indexers and data ingestion components. Technologies/skills demonstrated: - Rust-based core/typing integration (iota-core, iota-types). - Protocol design and change management (new MisbehaviorReport, ChangeEpochV4; score parameter integration). - Comprehensive testing paradigm (linting, compilation, unit/integration tests) and cross-repo coordination for framework updates.

Nov 1, 2025Month 2025-11 delivered foundational scoring, misbehavior, and epoch-reward capabilities for iotaledger/iota, centralizing the scoring logic and enabling score-based rewards in the consensus stack. The work focused on building a centralized Scorer component and integrating it with the Context and AuthorityPerEpochStore, laying the groundwork for auditable, epoch-aware rewards and improved validator accountability. In parallel, the team introduced versioned metrics and misbehavior reporting to support secure, cross-node visibility of performance data and malfeasance, while aligning core types across crates to support score-based rewards during epoch transitions.

Aug 1, 2025August 2025: Delivered a pivotal Consensus Scoring Enhancement for iotaledger/iota. Refactored and clarified the scoring logic in the consensus module, introducing a defined scoring approach that penalizes provable faulty behavior and equivocations with a score of 0. The new model also computes a score based on the absence of missing proposals and the absence of unprovably faulty blocks, with explicit weights assigned to each factor to improve reliability, decision-making, and resilience of the network. Commit reference: 0e2124ff10842612b747cf3795ef0157c9185e03.
