Multi-proposer consensus protocols let multiple validators propose blocks in parallel, breaking the single-leader throughput bottleneck of classic designs. Yet the modern multi-proposer consensus implementation has grown a lot since HotStuff. This workshop explored the implementation details of recent advances – DAG-based approaches like Narwhal and Sui’s Mysticeti – and revealed how implementation details translate to real-world performance gains. We focused on the nitty-gritty: how network communication patterns and data handling affect throughput and latency. New techniques such as Turbine-like block propagation (inspired by Solana’s erasure-coded broadcast) and lazy push gossip broadcasting dramatically cut communication overhead. These optimizations aren’t just theoretical – they enable modern blockchains to process over 100,000 transactions per second with finality in mere milliseconds, redefining what is possible in decentralized systems.

When a Rust program feels sluggish, adding instrumentation can shine a light on where the time is going. In this post, we’ll walk through a guided journey of using Tokio’s tracing framework and the tracing-texray tool to drill into performance issues. We assume you’re familiar with the basics of tokio-tracing (if not, see the Tokio tracing introduction for spans and events fundamentals). Our journey will start with a simple sequential task, then ramp up to parallel execution and illustrate how to maintain insight at each step.

Digital asset transfer systems are at a crossroads. An idea that first captured attention between 2020 and 2022—Byzantine Consistent Broadcast (BCB)—is now experiencing a revival with projects like Pod and Delta. In this post, we to show that while BCB can unlock incredible performance through parallel state execution, it also introduces important challenges, especially around expressivity and the scalability of reads. The goal is to explain why this approach is both exciting and demanding.
