Foundational Security

Not just against today's computers, but tomorrow's quantum-computers as well.

QRL is the first industrial implementation to utilize IETF standardised XMSS; a hash-based, forward secure signature scheme with minimal security assumptions.

An extensible address format ensures we are ready for anything out of NIST.

Implementation has been verified with two audits, one by red4sec and another by x41 D-sec.
