What do you do when the network goes down? Cut undersea cables, jammed base stations, a data-center fire—as long as your phone is still in your hand, your digital wallet is just fine. This is a dev-log of building offline verification, plus three small takeaways.Sun, 06 Sep 2026 04:47:00 GMThttps://mashbean.net/en/blog/2026/0904-1ui0is/https://mashbean.net/en/blog/2026/0904-1ui0is/Today I completed what I think of as the holy grail of digital identity services, and the piece of unfinished business I left behind at the Ministry of Digital Affairs last year: I got the digital wallet to support zero-knowledge proofs, made it actually work in production, and deployed it on Cloudflare while staying inside the free tier.Fri, 04 Sep 2026 16:54:00 GMThttps://mashbean.net/en/blog/2026/0903-1x7p95/https://mashbean.net/en/blog/2026/0903-1x7p95/I built "Show Your Wallet," a verification service that lets you deploy a digital-wallet verifier with one click. It's open source as of today (GPL-licensed), and it doesn't cost you a single cent.Thu, 03 Sep 2026 14:47:00 GMThttps://mashbean.net/en/blog/2026/0903-rphhg9/https://mashbean.net/en/blog/2026/0903-rphhg9/Two days ago, receiving an official document with a digital wallet used mock data; this time it was for real. I used my own wallet to receive a telecom e-card, opened a QR code, and picked up a parcel at 7-Eleven — and along the way I unpack why the official wallet is designed to keep the App, the trust layer, and the capability layer separate.Thu, 03 Sep 2026 03:50:00 GMThttps://mashbean.net/en/blog/2026/0901-1sefaj/https://mashbean.net/en/blog/2026/0901-1sefaj/Stitching a digital wallet, a mobile Natural Person Certificate, and a physical Natural Person Certificate driver together to test whether ordinary citizens could receive electronic official mail—and to spell out exactly where the line falls between what works and what doesn't yet.Tue, 01 Sep 2026 14:52:54 GMThttps://mashbean.net/en/blog/2026/0813-16xy2v/https://mashbean.net/en/blog/2026/0813-16xy2v/Sequential tests on a Taiwan Mobile 4G hotspot in Taipei.
