Billon Platform

The Billon Platform is a permissioned Layer 1 blockchain protocol designed for enterprise use cases combining digital identity, document management, and regulated digital currencies. Launched in 2023, the platform implements a unique Self-Sovereign Identity architecture where users maintain control of their private keys and data through client-side encryption. The system uses a cooperative proof-of-stake consensus mechanism with heterogeneous nodes that can run on mobile devices, enabling a distributed architecture that claims to be more energy efficient than traditional blockchain systems.

Key technical features include on-chain document storage, a multi-issuer model for managing different asset types, and embedded compliance controls for KYC/AML at the protocol level. The platform supports both sovereign and self-sovereign identity constructs, with private keys stored on users' devices. Notable implementations include credential issuance for Kielce University of Technology in Poland and selection as one of three protocols for the Reserve Bank Innovation Hub in India. The platform is also participating in the European Blockchain Services Infrastructure (EBSI) initiative for cross-border public services.

The system architecture emphasizes regulatory compliance while maintaining high performance, with independent tests showing throughput of 160 million transactions per day. Integration options include REST and SOAP APIs for enterprise systems, with deployment available both on-premise and as a hosted service. The platform implements eIDAS 2.0 standards and provides built-in support for PAdES and XAdES document signing standards. While primarily focused on enterprise and institutional use, the platform maintains an open network model where end users can access services through self-service interfaces without requiring direct IT integration.
