AuthenticDoc, a decentralized digital signature platform developed in El Salvador, was launched on November 13, 2025 at the Adopting Bitcoin Conference in San Salvador. The tool uses the Nostr protocol for its open-source, decentralized architecture, with Bitcoin-compatible cryptography to enable tamper-proof document verification and user-controlled private keys.
Co-founder Fabian of the Salvadoran firm Illuminodes announced the release during the conference. “The digital signature landscape is ripe for innovation, and AuthenticDoc is leading the way,” said Fabian. “We have leveraged the power of decentralized open protocol technology to deliver unparalleled security and control, effectively eliminating single points of failure that plague traditional solutions. Our platform provides a robust, tamper-resistant cryptographic verification and authentication solution that businesses can trust, while making it accessible and affordable.”
The startup, built by Bitcoiners, addresses vulnerabilities in centralized platforms like DocuSign, which controls about 70% of the $10 billion digital signature market. According to their press release, the industry is expected to grow to $60 billion by 2030 at a compound annual growth rate of 40%, fueled by regulations such as the EU’s eIDAS and the US ESIGN Act, in addition to remote work trends and AI-driven authenticity challenges.
The platform’s core features include reliable identity authentication, private key management for users, and compliance with ISO standards for business use. It eliminates the dependency on centralized storage by utilizing Nostr’s event-based system, where documents and signatures are cryptographically signed and distributed over a network of relays, ensuring robust data storage and distribution.
Diego, head of technology at Illuminodes, highlighted the shift away from legacy systems. “Our decentralized architecture gives users control over private keys and reliable identity verification, going beyond the vulnerabilities of centralized systems,” adding, “This isn’t just an incremental improvement; it’s a paradigm shift in the way digital signatures are secured and managed.”
AuthenticDoc is free for basic use, with paid tiers based on volume for businesses, undermining competitors’ license-based models. The platform supports global expansion from its headquarters in El Salvador, deploying local talent and regulatory support to target markets in Latin America, North America and Europe.
