The 2024 annual report from @BlockchainComns is here! It highlights our work toward an open, secure, and compassionate digital infrastructure, emphasizing interoperability and self-sovereign wallet standards through key projects: dCBOR, FROST, and Gordian Envelope. 🧵… [1/11]

I had really hoped this kind of tactic would never arrive in the US. I think it is time to stop using the term privacy and start calling these threats as coercive and potentially incentivizing violence.

This is just the beginning. We plan to release more tools and more courses such as:. – Learning BDK from the Command Line.– Learning FROST from the Command Line. If you’d like to help sponsor these works, let’s talk! [8/8]

FROST doesn’t just improve resilience (e.g. quorum signing despite share loss). It also opens up new decentralized patterns:.- distributed issuance.- distributed revocation.- edge identifiers & cliques ( .- and much more. [6/8].

Though this demo is focused on Bitcoin, our CLI tools also support other curves like ed25519. That means you can explore a wide range of FROST-based use cases beyond Bitcoin — for any Schnorr-based signature scheme. [5/8].

This CLI playground gives you an approachable, hands-on way to experiment with FROST. It’s based on our successful "Learning Bitcoin from the Command Line" model. We think it’s the best way to really understand the opportunities offered by FROST. [3/8]

Thanks to a new grant from @HRF, we’ve been building tools to make decentralized FROST signatures easier for devs. Our demo will showcase how to use these tools to sign a Bitcoin Taproot (BIP-340) Schnorr transaction using FROST. [2/8].

FROST is a powerful next-gen multisig protocol for Bitcoin — more efficient, more resilient. Join us next Wednesday 10am PDT for a live demo + dev discussion on using FROST with BDK and Taproot via our new CLI playground. 🧵… [1/8].

If you want to support true decentralization, amplify this message. Talk about what's wrong, what you don't like, and how you'd like to see it resolved. [11/13].

The self-sovereign identity community is caught between philosophical purity and practical irrelevance. We're at a time of reckoning where we're going to succeed with our ideals or fail. (Spoiler: Not looking great for the good guys right now.) [9/13].

This isn't just this one conference. We're having increasing problems even defining what decentralization is within our community. [8/13].

But Germany is simultaneously cutting deals with Google for a ZKP library—and though it could be a theoretical great foundation for our work, it currently ties you to the Google surveillance apparatus. [6/13].

Europe is doing superificially better. The Swiss presentation was all about privacy, democratic involvement, and achieving public buy-in. These are the right things to rah-rah about. [5/13].

On the other hand, you had Google and Apple. That's our representation? Corporations with their own interests!? (With those interests mostly being making money and achieving corporate lock-in.) [4/13].
