GM sirs, JamBrains here 🫡 We are cooking up our JAM client "GrayMatter". TLDR; it will make #Polkadot go faster. Our code is currently private. The only hint for now is this address. It remarks all our merged PRs 🤭 collectives.statescan.io/#/accounts/1ja…

Check out our API for JAM developers 👇 It makes it possible to compare functionality without sharing binaries or code. Basically an infinite pool of conformance tests. Beware, these values are based on our implementation. Eventually, we want to have most of our clients'

Eleven hours flight to Bangkok ahead, time to lock in with #Polkadot. See you there 👋

TL;DW for all who couldn't attend sub0 and listen to rphmeier's presentation about NOMT (Nearly Optimal Merkle Trie): It's going to be awesome 👀

The videos from sub0 are already out, and the following watch list from the Polkadot JAM day is worth watching:

JAM0 Implementers Meetup @ sub0/Devcon 7 had THIRTEEN teams with over 35+ people attending! Teams got a chance to meet each other all week long. We discussed JAM topics at length and enjoyed plenty of food and drinks together, in a community-led event. The future of trustless

When Gavin Wood drops rumours on future Polkadot JAM improvements: - Quantum Resistance - JAM Grid (interoperable JAM chains) - CoreVM - Service SDK Count us in for building this!

JAM call happening now! 26+ @polkadot JAM implementors from 13 teams developing in different programming languages: Elixir, Go, Python, Rust, C++, Zig, TypeScript, Scala.

We just published our new API endpoint to validate JAM test vectors 🎉 This allows other teams to test their block authoring logic without the need to share binaries. The format is the one that Colorful Notion introduced for this purpose. We will extend this to work for more

The Wizards are planning their next step. Are they summoning a new member 👀

Come watch the builders themselves talking about JAM! Two members representing JamBrains along with Tomek Drwięga from Fluffy Labs and Daniel Cukier from jamixir

🧠 Meet the teams implementing the JAM Protocol. Filmed at Sub0 Reset in Bangkok, this interview series explores how several implementer teams envision JAM, Web3, and the future of decentralized computing. The first episode drops this Thursday. Watch the teaser 👇

Oh hey that's us

Already tinkering with it. Left side GrayMatter and right side JamZig 🤝 Block hash ✅ Initial state root ✅ Posterior state root⏳ (Hint: this is very good for Polkadot JAM)

The PolkaJam Team published new test vectors, but no other team could validate them 🤔 Turns out it was an issue on their side that was since corrected. Good example of client diversity catching issues 🙌
