Polkadot is evolving, enter JAM, the Join‑Accumulate Machine, its ambitious successor to the Relay Chain. JAM transforms @Polkadot into a modular Web3 “supercomputer,” blending Polkadot’s sharding with Ethereum-like smart contracts, heres what you need to know 🧵👇 (1/6)

Shoutout to the gigichains and smart followers of polkadot (2/6)

How JAM works:
+ Off‑chain: Collect & Refine happen externally
+ On‑chain: Join & Accumulate perform core validation
Designed for scalability, parallel cores, continuous block execution, RISC‑V/PolkaVM runtime, 5mil+ TPS and exabyte‑level data
(3/6)

That means:
True multi‑core execution
Seamless, coherent compute across shards
Developers deploy parachains or service modules, all using $DOT, no new token on @Polkadot
(4/6)

Despite talk of a $JAM token, Gavin Wood and leadership say DOT remains Polkadot’s native token
JAM uses $DOT for governance, staking, fees
(5/6)


JAM marks the jump to @Polkadot 2.0, flexible, modular, high‑throughput, and developer friendly.
It unlocks DeFi, gaming, AI, offchain services all under a unified, coherent Layer 1 powered by DOT. (6/6)
