@javajam_io
Enterprise-grade JAM protocol implementation in Java.
🚀 Exciting milestone for JavaJAM! We just started our first internal testnet of the JAM protocol! 🎉 #polkadot #graypaper #jamprotocol #jam #kusama

🚀 Java devs, rejoice! Polkadot now speaks Java with the release of Jot from @method5. Jot a brand new Java based SDK now available for @Polkadot and Substrate chains. #Polkadot #Java #Web3
🚀 Introducing Jot — the new Java SDK for @Polkadot What's inside Jot: ⚡️ sr25519 + ed25519 signing 📡 Full JSON-RPC client (HTTP + WS) 🧩 SCALE codec + metadata decoder 🔗 Extrinsic builder + event parser 👉 github.com/methodfive/jot #Polkadot #Substrate #Java #Web3
Keeping pace with protocol evolution 👉 JavaJAM is now aligned with Graypaper 0.7.0. #Polkadot #JAM #Web3 github.com/javajamio/java…
After spending a year building JAM, I can say: this isn’t hype. It’s architecture for a world where truth and transparency aren’t optional. @pala_labs new doc about lays out the vision. #Polkadot #JAM #AI #Web3 👇
📽️ New Mini-Doc: Gavin Wood’s Vision to Reclaim Truth in the Age of AI Filmed during the 2025 JAM Tour across Asia, this short documentary dives deep into @gavofyork's vision for a world beyond black-box algorithms. 👁️Explore: - JAM - Polkadot’s next-gen decentralized…

🛠️ New JavaJAM build released — now fully compatible with Graypaper 0.6.7. 📦 Plus: Safrole STF test vectors for 0.6.7 to help other teams verify conformance. #Polkadot #Graypaper #Web3 #JAM github.com/javajamio
🚨 Graypaper v0.7.1 is here! Simpler transfers. Cleaner accounts. Smaller service IDs. Owned privileges support. Another sharp update from @gavofyork 👏 #JAM #Web3 #Graypaper github.com/gavofyork/gray…
🚧 Coming soon: a new Polkadot SDK for Java. Built from the ground up — clean, robust, and fully aligned with Substrate's evolving runtime. Everything you need to build with confidence on @Polkadot. No outdated libs. No workarounds. Just solid tools. #Polkadot #Web3 #Substrate
New JavaJAM build just dropped — full Gray Paper v0.6.6 implementation. ⚡️ github.com/javajamio/java… #jamprotocol #polkadot #graypaper
Gray Paper v0.7.0 is here! 🔥 🚀 Focus now shifts to polish, optimization & gas pricing as we push toward v1.0 #polkadot #jam #jamprotocol github.com/gavofyork/gray…
An experimental build of JavaJAM has been released — aligned with Gray Paper v0.6.5. Useful for other JAM implementations exploring early compatibility and cross-testing. Let’s JAM 👉 github.com/javajamio/java… #polkadot #jamprotocol #graypaper
Ignore the noise... Keep Building...

Thank you W3F for choosing the JAM implementers DAO to be apart of the DV program cohort 4!🔥 Having a DAO composed of highly skilled JAM teams ensures governance decisions are informed by those building the core technology

Calling other JAM implementors ⚡️ We’re exploring the idea of expanding our private testnet to have multiple client implementations participating. If you’re interested in joining forces to push JAM forward, let’s connect! #polkadot #graypaper #jamprotocol
True cross-client compatibility means a stronger, more decentralized JAM #polkadot #graypaper #jamprotocol
Holy fibonacci @polkadot fans! We just unlocked a major JAM Achievement: @javajamio imported all the JAM blocks we produced from our "tiny testnet" GP 0.6.2 Over the last 3-4 weeks, we proved that JAM implementers can resolve bugs quickly using graypaper.com…
The semi-coherency of @polkadot JAM protocol is one of its most elegant features! - Cores operate independently and in parallel (e.g., processing DeFi, NFTs, gaming), maximizing speed and scalability. - They only synchronize when tasks depend on each other (e.g., Core 1 needs…
Great to see @jamzig_dev trying our STF vectors! 👊🏻 These are crucial for ensuring interoperability and robustness across JAM implementations We encourage all JAM teams to try them out: github.com/javajamio/java… Let’s keep pushing JAM forward! #polkadot #graypaper #jamprotocol
🤝 JAM teams joining forces! Working on cross-implementation block imports & state root validation. Building a more robust ecosystem together ⚡️ JamZig ← JavaJAM ✅ asciinema.org/a/704796 Client diversity = immune system of JAM protocol 🛡️ #JAMProtocol @javajamio @Polkadot
We've generated some state transition vectors from our testnet for other JAM implementers to try ✅ This will help ensure alignment across implementations and strengthen protocol consistency. Let us know if you try them! 📊🔗 github.com/javajamio/java… #polkadot #graypaper #jam
