How Solana Scales: The SVM Explained ft. Joe | OnlyDevs Podcast

Description

In this video, we sit down with Joe, an engineer at Anza, the team behind Solana’s validator codebase, to unpack the core technology powering one of the fastest blockchains in the world. From the Solana Virtual Machine (SVM) to modular validator design, testing frameworks, and the future of on-chain programs, this episode offers a rare inside look at how Solana is engineered for scale. Whether you’re a developer exploring Web3 or simply curious about what makes Solana different from Ethereum and other blockchains, this deep dive will give you valuable insights into the infrastructure shaping the future of decentralized systems.
