Proof of Work - An interview with – Pavol Rusnák
summary
A hardware wallet company launches in 2012 after about a year of prototyping, ships an initial run of roughly a few thousand units, and grows to hundreds of thousands of users; early prototypes use a TI dev board then switch to an ST-compatible chip requiring significant firmware rewrites. Manufacturing hits injection-mold and tolerance problems, so production later moves to a local Czech supplier. Current engineering work includes SLIP-49 (Shamir 3-of-5 style seed splitting) and Model T SD card + PSBT support for fully air-gapped signing, plus research into CoinJoin/non‑interactive signing.
