PROFILE

Hamid Bateni

Worked on the alpenlabs/strata repository, delivering core backend and protocol features for blockchain checkpointing, data availability, and cryptographic verification. Built modular subprotocols and APIs for zk-SNARK proof validation, inter-protocol messaging, and secure checkpoint management using Rust and Python. Integrated in-process checkpoint provers with asynchronous task management and database-backed storage, enabling low-latency proof generation and retrieval. Enhanced system reliability by hardening validation logic, improving error handling, and supporting hardware wallet compatibility through cryptographic upgrades. Focused on maintainability and scalability by decoupling components, expanding testing frameworks, and implementing chunked storage for large data blobs, supporting robust, production-ready blockchain workflows.

Work History

April 2026

1 Commits • 1 Features

Apr 1, 2026

April 2026: Delivered in-process checkpoint prover integration for the strata client with configurable backends, enabling faster proof generation and retrieval. Introduced storage and task management for proofs, plus feature-flagged build/runtime gating and backend selection for easier maintenance and SP1 scaling. Result: lower latency, improved reliability, and a clear path for backend expansion and reorg-safe proof keys.

Mar 1, 2026

March 2026: Delivered a targeted fix in alpenlabs/strata to align DepositLog processing with bridge-v1, switching from DepositIntentLogData to the actual DepositLog and updating the payload to DepositMsgData. This corrected deposit message handling, improved data integrity and protocol compatibility, and reduced downstream reconciliation issues.

February 2026

4 Commits • 3 Features

Feb 1, 2026

February 2026 focused on strengthening visibility, security, and data availability for the Strata stack. Delivered L1-informed transaction status reporting by integrating L1 block info into tx statuses and decoupling btcio from full strata-params, enabling independent execution contexts and more reliable downstream DA status reporting. Hardened the ASM path with a bounds-aware AuxRequestCollector to prevent DoS from malicious L1 transactions. Introduced a chunked envelope storage layer and writer for large Data Availability blobs, with new EE databases container to unify EE state and enable cross-batch deduplication. Wired end-to-end DA pipeline into the Alpen sequencer with enhanced blob serialization and lifecycle management. These changes reduce risk, improve reliability and recoverability, and demonstrate scalable handling of large on-chain DA payloads.

Oct 1, 2025

October 2025 monthly summary for alpenlabs/strata focusing on feature delivery and API improvements in the checkpointing workflow. Delivered the Checkpointing Subprotocol and Proof API with SPS-50 envelope compatibility, enhanced parsing and verification, and robust checkpoint state management. Introduced a targeted API get_next_unproven_checkpoint_index to drive proof generation and streamline updates to the prover client.

September 2025

1 Commits • 1 Features

Sep 1, 2025

September 2025 monthly summary for alpenlabs/strata focused on expanding testing capabilities and inter-protocol support through a new ASM Debug Subprotocol (v1).

July 2025

1 Commits • 1 Features

Jul 1, 2025

July 2025 monthly summary for alpenlabs/strata: Delivered foundational Anchor State Machine (ASM) core subprotocol for zk-SNARK checkpoint verification, with refactors and new modules for error handling, genesis configuration, message processing, and verification logic. This work enables checkpoint transaction handling, validates state transitions, and prepares for inter-protocol communication, delivering business value by strengthening security and correctness of cross-protocol interactions.

Month: 2025-05 Summary: Focused on preserving data integrity in strict mode by hardening checkpoint validation in alpenlabs/strata. Delivered a targeted bug fix that prevents processing of checkpoints with invalid proofs, and refactored the proof verification to correctly handle empty proofs. Added functional tests to lock in behavior and prevent regressions. Impact: Strengthened data integrity, robustness, and reliability of checkpoint processing, reducing risk of corrupted state in strict mode. This improves overall confidence in data correctness for critical workflows. Technical highlights: Refactor of proof verification, explicit handling of empty proofs, dedicated functional tests, and code changes tracked under commit 4d015839f4195f4c0021875bb499446873545669 (Str 798).
