About
Quiet seven years.
Qashmore was designed by a cryptographer and software architect with more than 20+ years in system design, cryptographic protocol design and core-banking systems.
The key-management foundation beneath it, NPVDKGRS, was reviewed by a university cryptography research group in 2021 — informally, by letter, with positive findings — and has been running in production ever since, inside two regulated institutions: an electronic money institution licensed by Lietuvos bankas, and a MiCA-authorised crypto-asset service provider (CASP) licensed and supervised by Latvijas Banka. It is open source.
The payment protocol on top of it — the Pactena Protocol — is his independent work: fully specified, implemented, and demonstrated.
Several dozen groups across Europe work on the theory in this line, and the best of them could design this protocol. What is rare is not the mathematics. It is one team that also understands interbank settlement, what a supervisor will ask, and the two seconds at a till. That is applied cryptography — where the construction and the business reality are built at the same table.
Technology is good when it serves. When it is not decoration, but help.
