Speaking of privacy in Japan, Atsuko Muraki, a Japanese government official, spent 164 days jailed for a fraud she didn't commit — a case built on evidence a prosecutor literally falsified (he altered a floppy disk's timestamp). She was cleared only because a journalist caught the tampering. ~99% conviction rate. "Hostage justice." The death penalty. In a system like that, your testimony can be turned into your crime. Silence is a right. Privacy is a weapon to protect yourself. This is why we build. #privacy #freedomtech #nostr View quoted note →

Here's what we've actually been building — one by one. 🧵👇 Different products, one throughline: take money, payments, and knowledge back from the gatekeepers: View quoted note →

Hello Nostr world! We're Japan Bitcoin Industry (JBI), Japan's only Bitcoin-focused company. Japan still runs on cash, KYC, and platforms that rent you your own money — so we're building the way out, from Tokyo. We came to Nostr for the obvious reason: it's the one place built so no one can be the single point of failure. We'd rather build here, in the open, with the people who already get it — and we'd love to take it further: study sessions, builder meetups, hands-on workshops. In Tokyo or over a relay, our door is open. Come build with us. #bitcoin #lightning #nostr #cashu #freedomtech #japan #introductions
