JamZig

⚡️🛠️ A Zig-fueled implementation for the JAM protocol

[JamZig @jamzig_dev]

🚀 Putting #ziglang on the map with the #jam Protocol! Honored to present to @gavofyork and grateful for his inspiring graypaper – a true magnus opus 🎉. Thanks to @JAMdotTech for bringing everyone together and to @danicuki for the Italian spirit (and pizza!) to the table🍕🇮🇹

[JamZig @jamzig_dev]

We have not yet begun the actual performance optimizations for JamZig⚡, but @ziglang already shows promise. It is slightly faster than some of the highly optimized teams in the simplest path execution path. 👉https://t.co/gWQ9sL3bVD

[JamZig @jamzig_dev]

JamZig passed the full JAM GP 0.7.2 conformance suite ⚡️

Minifuzz → L2a → L2b → L3a → L3b. All green.

Zig-implemented JAM target. 1M-step fuzz, Safrole on, full-spec lanes.

🚀M1 MILESTONE: COMPLETE! 🚀

W3F Auditor Piet Wolff successfully fuzzed JamZig⚡ with 1M blocks using the fuzzer by @_davxy_. A massive win for the project as we move into the M1 Fellowship Review! 🤝

Next up? M2: Networking Implementation. ⚡️

Spent my free Sunday well visualising block execution 🚀 Optimised ~40% speed boosts on some execution paths!⚡️ Looking forward to the dashboard next performance run 🤠

Always a Joy working on the brilliant #JAMProtocol design of @gavofyork . ✨ @ziglang @_davxy_ @Polkadot

[JamZig @jamzig_dev]

First look at overall performance across JAM Implementors. Polkajam leads; JamZig (pure Zig language) is already competitive with debug logs enabled. Stripped benches coming soon — and yes, we expect to push this up! ⚡🤠

[Colorful Notion @colorfulnotion]

OMG! We now have 6+ JAM implementers with 100% clear JAM Conformance with a clear bill of health!

Throughout August, teams have posted a JAM "fuzz target" that receive challenging state transitions to ensure implementations conform to JAM spec. The implementations pass or fail each test case.

This is the future of @polkadot, which as always leads the whole of the Web3 industry.

and ... we are now ADDICTED to conformance 😅😂🤣😇

We're thrilled to announce our first CBRS Talk Show #Xspace on X! Join us Monday, August 5th, 7PM UTC to discuss #Web3 and #Blockchain with Starkerz from #Hive Blockchain and Boy Maas from #Jamzig.

📢Everyone's welcome!

If you don’t have time to watch the full video, here are the key takeaways we’ve put together for you.🫶

3 JAM client devs shared major updates:

🦀FastRoll (Rust) by @0xjunha
🍎 Boka (Swift) by @XiliangChen from @AcalaNetwork
⚡ Jamzig (Zig) by Boy Mass from @polana_network

They revealed progress on Milestone 1, insights from @Web3summit, and thoughts on PoP, ZK, and JAM governance. Here’s a recap 👇🧵

1/

Milestone 1 = JAM’s first big checkpoint

Clients must:

- Import and validate blocks
- Run runtime logic
- Output the correct post-state

A JAM fuzzer generates randomized blocks. If all clients produce the same state root, they pass Milestone 1.

2/

When testnet?

Testnet won’t go live until Milestone 2 is complete.

Why? Milestone 1 only tests runtime execution — not networking.

Milestone 2 will add peer-to-peer protocols. Only then can a proper JAM testnet form.

3/

Thoughts on Gavin’s major reforms announced at Web3 Summit

Bryan’s take: PoP could drastically cut security costs

Both PoS and PoW rely on high inflationary rewards.

PoP may:

- Reduce inflation
- Free up DOT for DeFi
- Align long-term value with utility

But: with staking yields reduced, user behavior will change — and the transition must be handled carefully.

4/

Thoughts on ZK + JAM?

All 3 devs agree:

- JAM can host ZK-powered rollups today
- JAM itself using ZK for security is still too early
- But it could happen — if zk tech gets 100x faster

Hybrid models might emerge.

5/

Thoughts on JAM Governance = Grey Paper + Editorial Board

Gavin remains chief editor.
A new technical board will co-maintain the spec.

🧠 Junha: JAM is “spec-first” — paper comes before code.
🛡️ Bryan: Transparency and rigor are critical.
✅ Boy: Committees help preserve protocol integrity.

6/

Polana x JAM: Solana SVM running on JAM

Boy Mass announced:

“You can now take Solana bytecode, deploy it to JAM, and it just works — with cross-program invocations!”

This makes JAM a universal execution layer. Huge for multi-chain future.

7/

The big picture:

JAM is the secure, modular compute layer.

But users won’t interact with JAM directly — they’ll use services built on top of JAM.

Core devs urge the community to:

- Read the Grey Paper
- Build apps
- Help refine the protocol

8/

Final words:

JAM isn’t just a new chain — it’s a new paradigm.

“We’re underestimating what JAM can unlock. The bandwidth it offers hasn’t been seen in blockchain before.” — Boy Mass

💬 Follow @polkaworld_pro for the Chinese recap.

[PolkaWorld @polkaworld_org]

Gavin just dropped a bold yet elegant idea:

Fix DOT’s total supply at π × 10⁹ (approx. 3.14B) — hardcoded into the JAM genesis block.

Community instantly asked us for a deep dive. So here it is👇

We're living through an unique moment in Web3 history 📚 @gavofyork's 14 years of (practical) blockchain wisdom "REFINED" into the https://t.co/rByyEltQXr, now being interpreted by >30 teams simultaneously. No central authority, just pure decentralised innovation at scale. Future historians will study this moment 🏛️ An implementation of the true Web3 philosophy ❤️

Lets go testnet 🔥🤠
