Protocol Berg v2: Gavin Wood - Beyond the Ledger: JAM and the Future of Scalable Decentr. Computing

Thu, Oct 2, 2025, 12:00 AM

Blockchain tech can be more than just a ledger: it can be a scalable global computing network, moving away from transaction-centric blockchain design into a decentralised computer one, changing usage patterns, development patterns and tooling. The Join-Accumulate Machine (JAM) is a new protocol aiming to make the usage of blockchain core radically un-opinionated, and to enhance the scalability and efficiency of blockchain networks. By enabling parallel data processing and reducing redundancy, JAM enables seamless collaboration between different applications, storing all application states in a shared environment. This approach facilitates more efficient data accumulation and consensus mechanisms, leading to improved performance and resource utilization. The adoption of JAM represents a significant advancement in blockchain technology: offering a pathway toward more scalable and robust decentralized systems. It is a forward-looking discussion on the future of Web3: showing blockchains can go beyond transactions, enabling decentralized computing with continuous execution flow. Gavin will provide an update on the latest developments on JAM, including achieved milestones by teams working around the JAM Implementer’s Prize, the JAM toaster and JAM tart, an exciting onchain Execution of DOOM which showcases JAM’s potential, and how to apply any application onchain: even those that don't resemble a blockchain/L2.
