The state of Gossamer April

Highlights

This cycle was relatively calm, yet we achieved significant milestones. We successfully completed two subsystems for ELVES: Availability Bitfield Distribution and Availability Distribution. Additionally, we finalized the existing scope for ElastiScaling.

Development

Polkadot finality

Timothy continued working on the integration of the GRANDPA package into the existing Gossamer codebase.

Polkadot Storage

Diego continued integrating the refactored db.Backend into our codebase.

Polkadot ELVES Implementation

Axay finished candidate descriptor for Elastic Scaling and RFC 103 implementation that is also used for ElasticScaling

Freddy FINISHED Availability Bitfield Distribution. Validators vote on the availability of a backed candidate by issuing signed bitfields, where each bit corresponds to a candidate. These bitfields help compactly determine which backed candidates are available, based on a 2/3+ quorum.

Haiko FINISHED Availability Distribution subsystem, which handles the distribution of availability data to peers. This includes chunks, PoVs, and AvailableData (PoV + PersistedValidationData), using request-response protocols.

JAM Protocol Implementation

Jimmy was working on block importing logic and doing some research on JAM-NP

Eclesio was busy on fixing bugs in our PVM implementation when it comes to RISCV test vektors.

Karan and Haiko were busy on implementing Host functions for PVM communication with host.
