PROFILE
Ayelet Zilber
Over a three-month period, contributed to the starkware-libs/sequencer repository by delivering three core backend features in Rust. Work included centralizing the Stateful Validator Trait into the Blockifier crate to streamline validation logic and reduce code duplication, as well as implementing a FIFO transaction queue for apollo_mempool to ensure in-order transaction processing in Echonet mode. Enhanced the mempool by enriching transaction metadata with block numbers and timestamps, improving contextual data and sequencing reliability. Focused on code organization, crate management, and asynchronous programming, these changes laid a maintainable foundation for future stateful validation and improved transaction integrity across the system.

Mar 1, 2026March 2026 for starkware-libs/sequencer: Delivered Apollo Mempool Block Metadata Enhancement, enriching TxBlockMetadata with block number fetched from Echonet and updating the mempool to support the new TxBlockMetadata structure (including timestamp and block number). This improvement enhances transaction context, prioritization, and sequencing reliability, with traceable changes via commit ccd905791592702ef84945bdf48b813de99b7094. No major bugs fixed this month in the provided data. Overall, the work increases data quality, observability, and reliability of the mempool and sequencing pipeline.

Feb 1, 2026February 2026 focused on delivering an ordering guarantee for the sequencer by implementing a FIFO transaction queue for the apollo_mempool in Echonet mode. This work enhances transaction integrity, predictability, and resilience of the sequencing path under production-like workloads. No major bug fixes were logged this month; primary effort centered on feature delivery and code quality improvements in the starkware-libs/sequencer repository.
