JAM featured at ETHLisbon- offers glimpse into the future of Web3 infrastructure

With a developer-led presence during ETHLisbon, JAM moves from concept to collective movement

[Lisbon, Portugal – May 6th, 2025] - The Join-Accumulate Machine (JAM) blockchain protocol, devised by Ethereum and Polkadot co-founder Dr. Gavin Wood, will be featured prominently at ETHLisbon from May 9th to 11th, 2025 with a JAM-themed booth and a keynote presentation exploring how the protocol is reshaping the future of Web3.

JAM is an open-source blockchain protocol that enables the execution of general-purpose computer code on top of blockchain architecture. By removing traditional blockchain-specific coding constraints while maintaining decentralized infrastructure, JAM allows developers to build and run any type of application directly on-chain. This shift paves the way for greater flexibility for developers while preserving the reliability and security that blockchain technology offers.

To encourage diverse implementations of the protocol, the Web3 Foundation launched the JAM Implementer’s Prize, offering up to 10 million DOT and 100,000 KSM, valued at approximately $100 million USD at the time of announcement. Development teams across the globe are working on JAM in various programming languages, fostering a collaborative and pluralistic developer ecosystem. While competing for the prize, these teams are building a growing community where they share knowledge, ideas, and experiences with one another.

During ETHLisbon, attendees will have the opportunity to visit the JAM booth, engage directly with implementers, get an early peek behind the curtain at the technology in development, grab exclusive merch, and enjoy a few surprises along the way. On May 9 at 4:30 pm local time on the main stage, Daniel Cukier, a JAM developer working in the Elixir implementation, will also deliver a keynote presentation titled “JAM: The Architecture Web3 Was Meant to Have.”

While previous public discussions about JAM have primarily come from Dr. Gavin Wood himself, this event marks a shift as the developer community takes the lead in sharing the project’s vision with a broader audience.

About JAM

JAM, the Join-Accumulate Machine, is an innovative open-source blockchain protocol pioneered by Dr. Gavin Wood who architected two most technically advanced blockchain projects - Ethereum and Polkadot. This technology reshapes the current blockchain landscape, marking a major turning point for the entire Web3 space. JAM enables the execution of general-purpose computer code on top of blockchain infrastructure, removing the blockchain specific coding constraints but maintaining all the features of the Web3 infrastructure. JAM shifts the blockchain paradigm to become a platform to host any type of Web3 applications.

About Polkadot

Polkadot is the powerful, secure core of Web3, providing a shared foundation that unites some of the world’s most transformative apps and blockchains. Polkadot offers advanced modular architecture that allows devs to easily design and build their own specialized blockchain projects, pooled security that ensures the same high standard for secure block production across all connected chains and apps connected to it, and robust governance that ensures a transparent system where everyone has say in shaping the blockchain ecosystem for growth and sustainability. With Polkadot, users are not just participants, they're co-creators with the power to shape its future.

About The Web3 Foundation

Web3 Foundation funds research and development teams building the technology stack of the decentralized web. It was established in Zug, Switzerland by Ethereum co-founder and former chief technology officer Dr. Gavin Wood. Polkadot is the Foundation’s flagship project.
