Jam Testnet Launch event
Overview
The Join-Accumulate Machine (JAM), which is intended to replace the Polkadot Relay Chain, repositions the network as a distributed computer that executes services across multiple cores. In January 2026, the first public JAM testnet went live, providing a shared environment for testing separate JAM client implementations. Under the Web3 Foundation's JAM Prize, numerous teams are developing JAM clients in various programming languages, and formal proposals for a mainnet upgrade are anticipated later in 2026.
