Non-Repudiation Primitives

Authentication

Non-repudiation primitives within cryptocurrency rely heavily on cryptographic authentication mechanisms, ensuring transaction origins are verifiably linked to specific private keys. Digital signatures, a core component, provide proof of intent and prevent plausible deniability, critical for dispute resolution in decentralized systems. These signatures, coupled with blockchain immutability, establish a robust audit trail, essential for regulatory compliance and trust building. The strength of authentication directly impacts the reliability of non-repudiation guarantees within the ecosystem.
