Blockchain stock ledger

StockTreasury

StockTreasury replaced fragmented, easily-altered paper and database cap tables with cryptographic certainty. Every issuance, transfer and ownership record for Delaware-registered companies was anchored to Guardtime’s KSI® blockchain — keyless, quantum-resistant signatures — so the history of who owns what could not be quietly rewritten.

Separating viewing from signing

I decoupled the viewing platform from the transaction-execution environment: the web app shows the ledger, while every state-changing action runs through PrimeSigner, a mobile app providing biometric two-factor authentication. Passwords — and the vulnerabilities that come with them — were designed out of the critical path entirely.

A microservices refactor took the product from MVP to enterprise-grade across 2020–2022, isolating the core ledger from communications and cutting technical debt while keeping 24/7 availability.
