The project aims to explore and prototype improvements to data propagation in the Sui blockchain. The focus will be on the first stage of the consensus protocol, specifically streaming consensus data as soon as transactions are committed, before they are bundled into certified checkpoints. This work will combine systems research, and hands-on implementation.

Background

Sui is a decentralized layer 1 blockchain that offers high throughput transaction speed at a low cost. Launched in 2023, Sui was founded by key members involved in Facebook’s Diem blockchain project. Sui currently achieves 320–350 ms p50 consensus latency and <700 ms end-to-end settlement latency for transactions, but non-validator nodes can experience additional delays before seeing the latest transactions. By streaming committed consensus blocks directly, full nodes could:

• Eliminate the extra 150–350 ms latency introduced by checkpoint certification.
• Allow applications (e.g., market makers) to observe transactions optimistically, as soon as they are committed.
• Improve real-time responsiveness of the network for latency-sensitive use cases.

This project investigates how to stream out consensus data from validators to full nodes immediately upon commit, and build a minimal viable prototype of this functionality.

Responsibilities

• Study and document the transaction lifecycle in Sui: from submission, consensus commit, checkpointing, to finality.
• Understand and analyse the Mysticeti consensus protocol and its role in transaction commitment.
