EP-36 Spark's Pivot: From DeFi Lending to RWA Deployment
In this episode of WuBlockchain Podcast, Sam MacPherson, co-founder of Phoenix Labs, shares how Spark has evolved from a DeFi lending protocol into a capital allocator managing nearly $4B across DeFi, CeFi, and RWA. He explains the Spark Liquidity Layer's role in optimizing yield--especially through tokenized U.S. Treasuries--while maintaining a 25% cash reserve to ensure stability. Sam discusses the platform's modular governance via the Sky-Star system, its push into the APAC market, and the upcoming SPK token launch for staking and governance. Transparency and on-chain auditability remain Spark's core strengths over traditional finance.

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