ChillDKG finally has a sister BIP that specifies the signing part of FROST! The draft already has reference implementation & test vectors. If you've looked at BIP MuSig before, this should look very familiar.

Our research team dropped a new BIP draft to finally specify secure distributed key generation as part of FROST for Bitcoin. We're calling it "ChillDKG". 🧊🥶 bitcoinmagazine.com/technical/the-…

Today we disclose Dark Skippy - a powerful new method for a malicious signing device to leak secret keys. With a modified signing function, a device can efficiently and covertly exfiltrate a master secret seed by embedding it within transaction signatures.

Twisting the idea from evil to benign: what would do with 6-8 bytes of free, private storage for each signature? Maybe your #miniscript BIP-388 wallet policy backup? A semi-serious thread🧵

My thinking is that it's possible to achieve security in a narrow but important definition: security against a "covert" HWW attacker. A covert HWW attacker will not make the device behave in any way that a user can distinguish it from an honest HWW.

Talks from Nashville's Bitcoin Wildlife event are now live 🔥 The thread below features presentations on STARKs, improved bridge designs, MEV, and more. First, we highlight Weikeng Chen | BIP-420 🐱’s presentation on a Circle STARK verifier in Script 👇

Excited to share our work on BitVM bridges: A novel trust-minimized protocol to bridge Bitcoins to second layers. Huge thanks to Lukas Aumayr, Alexei Zamyatin | Hiring, Andrea Pelosi, Zeta Avarikioti, and Matteo Maffei for their amazing contributions 🧡 bitvm.org/bitvm_bridge.p…

BitVM2 and BitVM Bridge: TLDR Today we released the BitVM2 tech and bridge paper! Huge thanks to brilliant яobin linus Lukas Aumayr Andrea Pelosi Zeta Avarikioti Matteo Maffei TLDR: - BitVM2 is a major improvement over previous BitVM versions. - BitVM Bridge is now the most

Hey Bitcoin Governance nerds, I put together a rough draft for an updated BIP process. Leave some feedback, maybe: github.com/murchandamus/b…

Is Tor still safe to use? According to the new statement from The Tor Project, regarding the investigative news story looking into the de-anonymization of an Onion Service, which was confirmed by the CCC (Chaos Computer Club), the answer is 'Yes!' "Please note, that for the great

Really impressive one round DKG implementation.

Excited to introduce the Shielded CSV 🛡️: Private and Efficient Client-Side Validation! Big thanks to co-authors Liam Eagen and яobin linus. Check out the whitepaper: github.com/ShieldedCSV/Sh… tl;dr: "The most interesting thing you can do with BitVM" (яobin linus) 👉 First

🪄scalable, private transactions secured by bitcoin consensus 🤝collaboration between Blockstream Alpen Labs ZeroSync 🔀 combines key primitives like recursive STARKs & CSV 🧱builds on prior protocols like zkCoins, Taproot Assets, RGB

Great work by ncklr, яobin linus and others. Looking forward to co-operate and start building with joint efforts, avoiding creation of siloed tech stacks.

Can confirm that the video is not fake and that it captures the sentiment of the group involved in the demo. We were instantly on-boarded without an on-chain tx, sent funds through the LN and did a unilateral exit (which is pending). Feels like I will have to learn more about

This is an excellent intro to Shielded CSV 🛡️, recorded before we settled on the name of the protocol. It also goes a little bit into the relationship and differences between zkCoins and Shielded CSV.
