Identity & Access
Rodolfo Novak (NVK) is a Canadian-Brazilian cypherpunk, designer, entrepreneur, and the CEO of Coinkite. A pioneer in Bitcoin physical security, he has spent over a decade designing specialized hardware signing devices. Under his leadership, Coinkite developed the COLDCARD series (including the Mk4 and flagship Q), the industry standard for air-gapped Bitcoin hardware wallets, as well as physical bearer assets like Opendime, SATSCARD, and TAPSIGNER.
- COLDCARD Air-Gapped Signing Architecture Architected the COLDCARD hardware wallet series (Mk1 to Mk4 / Q). Pioneered dual Secure Elements from different vendors (Microchip + NXP/Maxim) to mitigate supply-chain attacks, PSBT (BIP 174) air-gapped workflows over MicroSD/NFC, open-source firmware with reproducible builds, and physical anti-tamper features.
- Physical Bearer Assets (Opendime & SATSCARD) Invented Opendime, the first physical Bitcoin bearer asset that allows un-spendable private key generation until a physical seal is pierced, followed by SATSCARD, the modern NFC-based balance-bearing smartcard.
- NFC Hardware Security (TAPSIGNER) Architected TAPSIGNER and SATSCARD using ISO-14443 smartcard chips, enabling hardware key signing via smartphone NFC interfaces for self-custody apps and multisig coordinators (e.g., Nunchuk).
