Srini shares his journey from building NFT platforms and working at AWS to leading a project that’s tackling the blockchain trilemma head-on.

Whether you’re a developer, founder, or Web3 investor, this episode breaks down what makes Shardeum different—and why it could shape the future of blockchain infrastructure.

💡 What You’ll Learn

• The core problems with today’s blockchains (scalability, gas fees, decentralization)
