The Liquid hack negotiation is happening in OP_RETURN. So I turned it into a chat app.
Live, PGP-verified, with shared reactions, and a slot for the attacker's private key whenever he drops it.

Round 22. Fourteen hours after the public ultimatum, Blockstream replies. Encrypted. 4.9 KB, the longest message of the whole saga.
He said "all messages will be in plaintext" and threatened to publish the key. They answered with more ciphertext than ever. Whatever is in there, they're not saying it in public.
598.5 BTC still with him.

Still find it a bit surreal that you can pay for groceries with crypto at 137 SPAR locations in Switzerland. That runs on Open CryptoPay, which we built at @DFX_Swiss. Adoption isn't a conference demo — it's the checkout line.

🇨🇭SWITZERLAND: #Bitcoin payment in a supermarket using the Lightning Network 👀⚡️
There is no rational reason to be relaxed.
It's only a matter of time before the first traditional bank announces that it is discontinuing all services because continuing operations is no longer feasible. 🌚
Update: Boltz will stay disabled until further notice.
Our API remains available to process refunds cooperatively. In any case, unilateral refunds will work, as they do not depend on our infrastructure.
Our support team stays reachable.
To be clear: this is not a response to a single incident. Over the past months we have seen a steady rise in automated, AI-assisted probing of our infrastructure, and we have dealt with several exploits. Each was contained, but the pattern is clear: attackers now iterate faster than a team our size can find and patch. In the past few days alone we saw a drastic acceleration, and we do not believe this asymmetry will reverse. After reviewing the results of our own recent security scans, we cannot responsibly re-enable Boltz swaps, especially as we are being actively targeted by what appear to be multiple resourceful groups while we race to deploy fixes.
What we are seeing is a major paradigm shift for Bitcoin services operating on an open source stack, and it needs careful analysis. Do not expect swap services to resume shortly.
To be explicit: no user funds were ever at risk. Boltz is non-custodial by design. And as a fully bootstrapped company, the losses were ours alone.
We don't know yet how things will continue from here, but we'll keep you posted as soon as we have had the time to catch our breath and make a decision 🙏

After giving it some serious thought, I'd say the only truly sensible setup is a multi-signature arrangement using two different providers. Or a 2-of-3 setup using three different providers.
I have a report full of security issues of a software I'm working on.
Codex won't fix them because of Cyber guardrails
Fable won't fix them because of Cyber guardrails
Kimi K3 fixed them all. No restrictions, just gets the job done.
This will end badly for OpenAI & Anthropic.

RealUnit in Your Hands
Together with @Real_Unit_ Schweiz AG, we developed the new RealUnit app.
For the first time, investors can buy and sell RealUnit share tokens directly within the company’s own app and securely hold them in their personal wallet.
The integrated DFX on- and off-ramp connects users’ bank accounts to the blockchain, enabling a simple and seamless process for deposits and withdrawals.
The RealUnit app developed by DFX brings the entire user journey into a single application: from depositing funds and buying or selling RealUnit share tokens to self-custody in a personal wallet.
Another step towards simple and direct access to tokenized real-world assets.

Was ist die Leistung einer KI wert und welches Preismodell passt dazu?
Unser CEO Cyrill war zu Gast im Podcast von @Real_Unit_.
Im Mittelpunkt stehen KI-Preismodelle: Wie lassen sich KI-basierte Leistungen sinnvoll bepreisen und bezahlen?
Darüber hinaus geht es um neue Zahlungsmöglichkeiten, „gesundes Geld“ und Blockchain – und um die Frage, wie diese Entwicklungen zusammenspielen.
Ein lockeres Gespräch über Technologie, Geld und Geschäftsmodelle in einer zunehmend KI-geprägten Welt.

Bitcoin payments are public by default. zkCoins is designed as a private client-side-validation layer anchored to Bitcoin—without a separate chain, native protocol token or consensus change. Payment details stay off-chain. zkcoins.com

Introducing Mosaic 💥🔫
A practical fault-proof verifier implemented in Rust, with security strong enough to host financial markets on Bitcoin.
Mosaic realizes the Glock paper's vision at a low onchain cost.

The next few years will bring a sharp increase in the amount of vulnerabilities found, systems breached, and data leaked.
The importance of cold storage self custody for your bitcoin will become even more obvious.

To provide more blockspace for private ShieldedCSV transactions it suffices to do a softfork as you need only arbitrary block space, i.e., no non-witness data.
