Certen Protocol
Certen is the first dSIG (Decentralized Security, Identity, and Governance) protocol—a no-code cross-chain governance layer for institutional blockchain. Organizations managing $840B in digital assets lack basic governance infrastructure. Current solutions force a bad tradeoff: MPC platforms cost $50k-200k/year and rely on centralized policy engines, while smart contract multisigs run $100k-300k/year and have proven vulnerable to exploits. 75% of crypto losses stem from access control failures. Certen solves this with protocol-native governance enforced by blockchain consensus—no centralized servers, no smart contract risk. What we deliver- No-code governance engine for hierarchical approvals and delegated permissions - One identity governing assets across Bitcoin, Ethereum, Solana, and other chains - Complete on-chain audit trails - Public, permissioned, or private network options for compliance - 90% lower cost ($5k-25k/year) We operate as decentralized SaaS: institutions pay fixed USD fees for governance operations, not annual subscriptions. Certen is a fork of Accumulate, which evolved from Factom—representing a decade of protocol innovation in identity-based blockchain architecture. Launching Q2 2026.
