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.
00:00- Check out our latest @FrostsnapTech prototypes. Hardware wizardry @sakak_musdom App ingenuity @LLFOURN Welcome to the future of #bitcoin self-custody ❄
00:00 - Once every few months I get to witness someone learn that having 2-of-3 seed phrases alone for legacy multisig is insufficient for recovery. You also need the ALL of the public keys to spend from the multisig.
- Thrilled to announce what we've been building in the shadows: @FrostsnapTech - easy, personalized, secure #Bitcoin self-custody for everyone We're building hardware, firmware, and cryptography. For a new era of Bitcoin multisignatures & beyond frostsnap.com/introducing-fr…
- 'Unlicensed money transmitter' is the new 'Cryptographic munitions exporter'
- ⚡️👀 NOLOOKING @UMBREL DEMO 👀⚡️ Brand new app for opening multiple lightning channels in a single transaction, using PayJoin First, install nolooking:
00:00 - We've investigated the capability of adding or removing signers in a FROST multisignature, without altering the public key or having to move funds 🪄📝 Imagine you lose a hardware signing device and want to add a replacement!🔐🧊 Check out the details:
- Replying to @BitcoinIsSaving and @pierre_rochardFact: most bitcoin critics have never made a single transaction
- Anyone noticed that spending from your multisig lately has been costing a lot? Script multisig costs you sats: * Transactions from a 2-of-3 cost roughly ~70% more than single-sig. * 3-of-5s cost roughly +120% more. Fee market going ballistic, hope you consolidated your utxos :/
- running FROSTR github.com/nickfarrow/fro… This was the motivation i needed (+ thanks for code snippets from moe-bot @rot13maxi ). Time to make shitpost DAO?
So here’s a funny thought: Nostr messages are signed with schnorr signatures. You can aggregate them. You could use MuSig or FROST/ROAST for nostr events. You could multisig your nostr Or do collaborative shitposting. Or a shitpost DAO. - thats like 4 bits is there a particle beam running through your pc
