AuthenticDoc, a decentralized digital signature platform developed in El Salvador, was officially launched on November 13, 2025, at the Adopting Bitcoin conference in San Salvador. The platform utilizes the Nostr protocol for its open-source, decentralized architecture, incorporating Bitcoin-compatible cryptography to enable secure document verification and user-controlled private keys.
During the conference, co-founder Fabian from the Salvadoran firm illuminodes announced the release of AuthenticDoc. Fabian stated, “The digital signature industry is ready for innovation, and AuthenticDoc is leading the way. By leveraging decentralized open protocol technology, we are able to provide unmatched security and control, eliminating the vulnerabilities present in traditional solutions. Our platform offers a robust cryptographic verification and authentication solution that businesses can rely on, all while remaining accessible and cost-effective.”
Created by individuals involved with Bitcoin, the start-up aims to address the weaknesses seen in centralized platforms like DocuSign, which currently dominates about 70% of the $10 billion digital signature market. The industry is expected to grow to $60 billion by 2030 with a 40% compound annual growth rate, driven by regulations such as the EU’s eIDAS and the U.S. ESIGN Act, as well as the rise in remote work practices and AI-driven authentication challenges.
Key features of the platform include trustless identity verification, user-controlled private key management, and compliance with ISO standards for enterprise usage. By utilizing Nostr’s event-based system, AuthenticDoc eliminates the need for centralized storage, ensuring secure data storage and distribution through a network of relays.
Diego, the head of technology at illuminodes, emphasized the shift away from legacy systems. “Our decentralized architecture empowers users with control over their private keys and allows for trustless identity verification, moving beyond the vulnerabilities of centralized systems,” he explained. “This isn’t just an incremental improvement; it represents a fundamental change in how digital signatures are secured and managed.”
AuthenticDoc offers a free basic version for individual users, with paid tiers available for enterprises based on usage volume. The platform is poised for global expansion from its El Salvador headquarters, leveraging local talent and regulatory support to target markets in Latin America, North America, and Europe.
