01Node

01Node is a Romanian validator operator that started with the Cosmos genesis block in 2019 and runs its own bare metal rather than rented cloud: its own AS41536 autonomous system, dual 10Gbps uplinks and Tier III facilities, paired with hardware HSMs and Horcrux threshold signing that splits signing keys across machines to avoid single-point exposure and double signing. Work splits into validator operations, public RPC and APIs, snapshots and sentry nodes, and white-label nodes for exchanges and funds.

It currently validates more than 40 mainnets, manages over 540 million dollars in delegated assets and serves more than 50,000 delegators; on EigenLayer it runs more than 14 actively validated services, each isolated with an exposure cap. On Sui it publishes both GraphQL and gRPC endpoints with a 5% validator commission. Operations use a multi-region sentry layout where signing nodes talk only to sentries and never expose a public address, backed by double-sign detection scripts and automated alerting; IBC relaying, state sync and snapshot services are listed per chain and available on subscription.
