EP-35 Shardeum: Auto-Scaling Layer 1 with Dynamic Sharding

<p>In this episode, Shardeum CTO Srinivasan Parthasarathy shares how Shardeum is building an auto-scaling Layer 1 blockchain using dynamic state sharding and a blockless transaction model. The architecture enables linear scalability while keeping node requirements low, offering a unique balance between performance and decentralization.</p><p>He also discusses lessons from testnet operations, key bug bounty findings, and the network's security approach, including a custom "Proof of Quorum" consensus that rotates node responsibilities every 60 seconds. As an open-source, community-driven project, Shardeum aims to launch its mainnet on May 5, with smart contract support and incentive programs to follow in a phased manner. <a href="https://wublock.substack.com/p/inside-shardeum-auto-scaling-layer?utm_source=publication-search">Text summary</a></p><p>Timeline:</p><p>00:00 Intro &amp; Shardeum overview</p><p>01:47 How does Shardeum scale while keeping node access low?</p><p>07:44 What are th...
