On December 19, news came that Gavin Wood, the founder of Polkadot, recently announced the latest progress of JAM during the Polkadot Fellowship Call. Important information is as follows: 1. JAM SDK: Parity has released v0.1, supporting Rust developers to create services and upload them to JAM. 2. CoreVM: Parity will launch the initial version of CoreVM by January at the latest, which is the first official service; it innovatively allows arbitrary code to run on the blockchain without being constrained by Gas limits or block limits, achieving true Turing completeness; in addition, Gavin hopes to release a demo of the DOOM game soon, which will showcase the capabilities of JAM and PVM. 3. JAM 1.0: The fully functional version is expected to be completed before April 2025 and enter the audit phase. 4. JAM V2 planning: Introducing quantum resistance and JAM Grid, supporting the integration and expansion of multiple instances.
