Manifoldchain: Maximizing Blockchain Throughput via Bandwidth-Clustered Sharding

Network and Distributed System Security (NDSS) Symposium 2025 · Day 1 · Blockchain Security 1
In a presentation at the NDSS Symposium, researcher Chunjiang Che introduced **Manifoldchain**, a novel sharding protocol designed to significantly enhance blockchain throughput. The talk, titled "Manifoldchain: Maximizing Blockchain Throughput via Bandwidth-Clustered Sharding," addresses the persistent challenge of low transaction processing speeds in decentralized networks, a fundamental limitation hindering widespread blockchain adoption. Compared to centralized payment systems like Visa, which can handle over 24,000 transactions per second (TPS), current blockchain applications often struggle to exceed 20 TPS. This stark disparity underscores the urgent need for scalable solutions.

Manifoldchain is legitimate distributed systems research with a clean core insight — cluster miners by bandwidth to stop fast shards from being throttled by stragglers. The protocol stack built on top (sharing mining, inclusive/exclusive blocks, flow proof, predicted mining) shows real engineering depth. It's a solid NDSS paper talk: technically sound, modestly novel, but not the kind of work that redraws the map.
