CoinVoice has recently learned that Polkadot founder Gavin Wood tweeted that the "Initial Jam Specification: A Proposal for the Future of Polkadot" has been published in the Gray Paper.
Jam stands for Join-Accumulate Machine, a semi-consistent, scalable, trustless virtual machine that combines the protocols of Polkadot and Ethereum elements, providing a global single-piece permissionless object environment similar to the Ethereum smart contract environment, and is equipped with parallel secure sideband computing on a scalable node network. The overall model of services provided is mainly driven by Polkadot's underlying architecture.
Jam allows anyone to deploy code as a service on it and charge fees based on the resources used by the code. It may launch a CoreChains service compatible with Polkadot. [Original link]
