Gavin Wood has published a proposal about the future of Polkadot in the white paper

ChainCatcher news, Polkadot founder Gavin Wood tweeted that the "Initial Jam Specification: A Proposal for the Future of Polkadot" has been released in the gray paper.

Jam stands for Join-Accumulate Machine, which is a semi-consistent, scalable, trustless virtual machine that combines elements of Polkadot and Ethereum protocols. It provides a global single-instance permissionless object environment similar to the Ethereum smart contract environment, along with parallel secure sideband computing on a scalable node network. The overall service model is primarily driven by Polkadot's underlying architecture.

Jam allows anyone to deploy code as a service on it and charges corresponding fees based on the resources used by the code, or a CoreChains service compatible with Polkadot will be launched.
