# 01node

> Sovereign bare-metal infrastructure for blockchain validators. 40+ proof-of-stake networks, 99.99% uptime, six years of production operation. Bucharest-based, two Tier III datacenters, AS41536, owned hardware end to end. Disclosed-incident history at https://01.ro/security#disclosed-incidents.

01node is a professional validator operator that has been running production infrastructure since the 2019 Cosmos Hub mainnet genesis. The company operates validator clusters with YubiHSM-backed keys, Horcrux threshold signing on Cosmos chains, Web3Signer with slashing protection on Ethereum, and Distributed Validator Technology (Obol + SSV) on the five Lido Simple DVT Module clusters where 01node is a signed Node Operator. Founder Claudiu Nae is CISA-certified since 2004. ISO 27001 + ISO 9001 certified. SOC 2 Type II on the 2026-2027 compliance roadmap.
