Last month, Jan ported Quake to run on-chain with JAM (built on PolkaVM) — the demo now lives fully on-chain, while full gameplay runs smoothly off-chain. 🕹️
He’s inviting more real-world software demos to showcase JAM’s general-purpose compute power.
Meanwhile, he shipped a secure worst-case gas model, and is now working on subjective metering:
stake if your code runs fast, get slashed if it doesn’t ⚖️
JAM isn’t just faster than EVM
It’s chasing bare-metal speed.
💥Breaking news!
• Westend staking + gov now live on Asset Hub – first big step in @Polkadot's move from a “heavy” relay chain to a lean consensus layer.
• @subscan_io already updated.
• @kusamanetwork migration: 15 August
• @Polkadot migration: mid-September
• DOT reserve moves from Relay Chain → Asset Hub (asset ID unchanged) → parachains must update their XCM paths ASAP.
1⃣What’s a “reserve location” move?
Every asset in Polkadot has a chain where the real balance lives. Today DOT’s reserve is the Relay Chain, after the move it’s Asset Hub – same DOT, new home.
2⃣ Why bother?
• Strip the Relay Chain down to pure consensus + validation
• Asset Hub = faster feature roll-outs (local gov, upgrades, new asset logic)
• Unified asset handling across the whole ecosystem
3⃣ Heads-up for DOT holders
• Wallets/DApps must update paths or you’ll see “0 balance” 🔍
• All parachains must patch DOT routes or transfers will fail.
• UX: users will need clear messaging – DOT isn’t gone, it’s just on Asset Hub.
• DEXes/liquidity pools using old paths risk temporary lockups – adjust early!
4⃣ Dev checklist ✔️
• Update XCM config to trust both Relay Chain & Asset Hub (can be done now)
• Test DOT flows against Asset Hub
• Verify bridges, swaps, payouts
5⃣ Why important?
• Redefines DOT’s technical home
• Unlocks faster, cheaper cross-chain UX
• Preps the Relay Chain for JAM & Elastic Scaling
For users: use a wallet that recognizes Asset Hub.
For builders: time to ship your updates.
