What is JAM and why are 38+ teams building it in 15+ languages? 🤔 Here’s a recap from the Polkadot Blockchain Academy Lucerne roundtable: 1/🌐 JAM = Join-Accumulate Machine. It’s a complete rewrite of Polkadot’s core. Minimal, efficient, and designed to be understood by one person. JAM strips away governance, tokens, smart contracts — and turns them into modular services. 2/ Why rewrite @Polkadot? Because the current relay chain became too complex to evolve. JAM is Polkadot’s new “kernel” — cleaner, faster, and future-proof. “Build a system one person can fully comprehend.” – the JAM motto. 3/ 38+ teams are implementing JAM in TypeScript, Elixir, Rust & more. Why? 🧠 Decentralized expertise 🔧 Diverse dev ecosystems 🤝 Shared tooling, open coordination JAM isn’t just a protocol — it’s a movement. 4/ What’s in it for builders? Sure, there’s the JAM Prize. But most panelists care more about: ✅ Owning their infrastructure ✅ Advancing Web3 ideals ✅ Becoming long-term protocol contributors This isn’t a sprint — it’s a 10-year journey. 5/ JAM devs follow 5 milestones: 1. Block import working 2. Full node implemented 3. Kusama-level performance 4. Polkadot-level readiness 5. Third-party security audit ✅ Many teams are approaching M3. Testnets expected in 2025-2026. 6/ Will JAM replace Polkadot? Not quite. Polkadot is migrating to JAM, step by step. Governance, assets, and staking are already moving off the relaychain (hello Asset Hub & Polkadot Hub). Parachains will still exist — as JAM services. 7/ JAM isn’t just for parachains. It unlocks: 🌍 New execution models (Coreplay) ⚙️ Custom services (Gov, ID, Contracts) 🔁 Cross-chain infra & MEV control 🏛️ Sovereign infra for governments “If JAM only replicates Polkadot, it failed.” 8/ JAM won’t upgrade on-chain like Polkadot. Instead: 🔧 Hard forks will happen 🤝 Governance + Fellowship will lead ⚙️ Teams like JAM DAO are forming to coordinate voting and upgrade paths Yes, real decentralization is messy — and worth it. 9/ Tools being built: 🧪 JAM VM runners 📜 Git-on-chain commit trackers 📖 Graypaper explorers 📊 Network dashboards 📦 SDKs & testing frameworks Dev-friendly from the ground up. 10/ So why does JAM matter for non-technical users? Because it lays the invisible groundwork for: ⚡ Lower fees 📲 Faster UX 💡 More innovation 🏛️ Truly sovereign infrastructure If you believe in Web3, you believe in JAM. 11/ Full roundtable from @Polkadot Academy Lucerne featuring builders from @fluffylabs_dev, @jamixir, @jam_brains, and @Web3foundation — watch it below 👇 RT if you’re bullish on open infra for the next decade!
