Chaumian Ecash bringt eine 40 Jahre alte Cypherpunk-Idee zurück: digitales Bargeld, das der Herausgeber selbst nicht nachverfolgen kann. Wie Cashu und Fedimint auf Bitcoin funktionieren, wofür sie gut sind und warum sie ausdrücklich nichts für deine Ersparnisse sind.
Ich habe Liquid lange als spannende Smart-Contract-Ebene für Bitcoin gesehen – zeitverzögertes Escrow, das mit Lightning-HTLCs kaum umsetzbar ist. Heute sehe ich das anders. Warum ich meine Meinung geändert habe und was Cashu und Fedimint damit zu tun haben.
Four decades of blind signatures show that one algebraic trick, letting someone sign what they cannot see, protects ecash and CoinJoin.
A unit of account layer that separates pricing from settlement, enabling price coherence, competitive differentiation and natural participation in merchant federations.
After that first Lightning-paid burger in 2024, I couldn’t look at my 14-year consulting practice the same way. I am a Bitcoiner, but I am also a realist: I know the 'Great Transition' won't happen overnight. To bridge the gap between TradFi and the Sovereign Web, we need more than just hope—we need reliable on-ramps, community-led custody, and a new breed of hybrid infrastructure. Here is how I’m evolving Simon Consulting to help entrepreneurs navigate the messy, exciting middle ground between the Euro and the Satoshi.
Gathers the Circle argues that refugee “digital identity” programs fail because displacement is defined by unreliable power, unreliable internet, and broken institutions. So identity must work offline first and live with the person, not in a database. It proposes a practical, deployable “camp-in-a-box” stack: $0.80 NFC “Name Tag” tokens that hold cryptographic keys and enable physical MFA; “Camp Cash” scratch-off bearer notes denominated in sats for private, offline exchange; and a peer-attestation reputation layer that rebuilds trust without documents. When connectivity disappears entirely, the system continues through Bluetooth mesh networking, then later syncs to global relays and Lightning when any link comes back online. Creating a three-layer infrastructure (physical, local digital, global digital) designed to survive censorship, surveillance, and collapse.

Fedimint Overview and Fedipool Theorizing
After my 2022 layoff, I deepened my involvement in Bitcoin. Joining a BitDevs meetup introduced me to industry experts. By actively engaging, asking questions, and taking initiative in open-source projects, I built my reputation and expertise. This proactive and inquisitive approach eventually led me to earn an OpenSats grant. Key takeaway: Dive in, learn, and always question.
In the recent Fedimint update, progress was made in resolving flaky tests in fedimintd, discussing audit summary improvements, optimizing auditing code for LN contracts, and adding TOR support. Notable PRs included enabling route hint configuration, handling sub-1 sat invoice payments, and prefixing ecash notes with the fedimint ID. A new release tag "v0.1.0-rc1" was introduced, with plans for a regular release cadence, while developers were advised to anticipate migration requirements between releases.
