El Salvador has officially launched AuthenticDoc, a decentralized digital signature platform, during the Adopting Bitcoin conference held on November 13, 2025. This innovative tool leverages Nostr protocol and Bitcoin-compatible cryptography to offer a secure solution for document verification.
Co-founder Fabian of the Salvadoran company illuminodes introduced the platform, stating, “The digital signature landscape is ripe for innovation, and AuthenticDoc is leading the charge.” He emphasized the platform”s ability to provide unmatched security and control while removing the single points of failure typical in conventional systems.
AuthenticDoc directly addresses the vulnerabilities associated with centralized platforms like DocuSign, which dominates approximately 70% of the $10 billion digital signature market. The industry is expected to expand to $60 billion by 2030, driven by a compound annual growth rate of 40%, spurred by regulations like the EU”s eIDAS and the U.S. ESIGN Act, as well as the rise of remote work and AI-driven authenticity concerns.
The platform offers key features such as trustless identity verification, user-controlled private key management, and compliance with ISO standards for enterprise applications. By utilizing Nostr”s event-driven architecture, AuthenticDoc ensures that documents and signatures are securely cryptographically signed and distributed across a relay network, thus eliminating reliance on centralized storage.
Diego, the head of technology at illuminodes, highlighted the transformative nature of this platform, stating, “Our decentralized architecture empowers users with private key control and trustless identity verification, moving beyond the vulnerabilities of centralized systems.” He noted that this innovation represents a significant shift in the security and management of digital signatures.
AuthenticDoc is available for free for basic usage, with premium tiers based on transaction volume for enterprises, offering a cost-effective alternative to existing license-based models. With its headquarters in El Salvador, the platform is strategically positioned for global expansion, leveraging local talent and regulatory backing to penetrate markets across Latin America, North America, and Europe.
