Polkadot is entering a new era with the JAM Protocol (Join-Accumulate Machine) ‼️

@Polkadot biggest upgrade yet, merging the best of Ethereum and Polkadot into a unified, scalable, and composable ecosystem.

What’s JAM all about?

•🔗 Universal Deployment – No more parachain auctions. Anyone can deploy services like smart contracts, rollups, or runtimes permissionlessly.
•💡 Cross-Chain by Default – Built-in XCMP support lets all services talk to each other smoothly.
•🧠 New VM + Multichain Contracts – Say hello to the Polkadot Virtual Machine (PVM) and “accords” (multi-shard smart contracts).
•⚙️ Simplified Architecture – No mempools. No gas bidding. Just clean, efficient work packages processed in parallel.
•🌉 Polkadot + Ethereum Energy – JAM bridges both ecosystems to create a truly modular Web3 future.

“JAM turns Polkadot into a supercomputer for interoperable Web3 services — fast, flexible, future-ready.” – Gavin Wood

With JAM, Polkadot is redefining what a next-gen blockchain can be.
