DEFINED. ENFORCED. IMMUTABLE.
A novel security architecture eliminating local attack surfaces through blockchain-based storage and cryptographic key derivation.
Traditional password managers store encrypted master keys locally on user devices.
Stolen devices provide time for brute-force attacks on locally stored encrypted vaults.
Local storage exposes encrypted credentials to extraction and offline analysis.
Account-based systems require server infrastructure and create recovery vulnerabilities.
Storing what should be ephemeral—cryptographic keys persist when they should vanish.
BlockWallet eliminates local persistence entirely through a novel architecture combining:
Keys are generated on-demand from user passphrases through Argon2id key derivation, exist only in protected memory during active sessions, then are cryptographically wiped.
Encrypted password entries are stored on blockchain infrastructure, eliminating local database vulnerabilities and enabling distributed access without account systems.
When idle, devices contain zero cryptographic material. Device theft yields nothing—no keys, no encrypted vaults, no attack surface.
Security through absence, not encryption strength.
Eliminate local credential storage for remote workforce. Zero persistent keys equals zero exfiltration risk from stolen or compromised devices.
Multiple cryptographically isolated vaults without account creation. One installation, infinite security contexts.
High-security credential management with regulatory compliance benefits from zero-persistence architecture.
HIPAA and confidentiality requirements met through elimination of local data storage vulnerabilities.
Zero-persistence protects source confidentiality and prevents unauthorized access to sensitive communications infrastructure.
Mission-critical credential security that meets stringent security clearance requirements and prevents credential compromise from lost or stolen devices.
