JAM is the anticipated future protocol for Polkadot, being implemented by multiple teams across different programming languages. The JAM Gray Paper outlines the protocol, and the Web3 Foundation has shared initial test vectors with participating teams here.
This repo contains the latest jamduna binaries (Linux + Mac) targeting 0.6.5 and some data.
Current release is 0.6.5.x -- the jamduna binary can do fallback + safrole with polkajam in tiny testnets (1+5, 2+4, 3+3, 4+2, 5+1).

Terrific - submit an issue with your findings! See the Releases for how we resolved previous issues with others. Please avoid sharing code, however, and instead use GP references and links to a specific state transition file. We have been able solve almost all problems within 48-72 hours or raise questions in the W3F repo or Lets JAM Matrix Room
