INTRO

The Join Accumulate Machine was designed by top-notch blockchain researchers and is described in the graypaper. It aims at being a successor to the Polkadot Relay Chain and is currently being implemented by multiple teams.

PRIZE

A prize pool of 10 MILLION DOT is provided by the w3f to incentivize multiple client implementations. This pool is spread over different language sets and up for grabs to anyone.

CLIENTS

Different teams are working on client implementations for the JAM chain in parallel. The goal is to achieve client diversity from day one to facilitate network stability and ensure unambiguity of the spec.

TECH

A few high lights of the JAM tech stack include a universal Virtual Machine, novel ZK cryptography and a unique block authoring algorithm. This allows JAM to offer dynamic execution sharding and atomic composability across shards.
While sharing - not sharding - security.
