node101 is a blockchain-native validator and product development team based in Türkiye and Paris, with a mission to empower permissionless systems. We operate secure validator infrastructure across 20+ leading networks including Celestia, Cosmos Hub, Starknet, Walrus, and Ika.

Beyond validation, we actively contribute open-source tools, organize developer events, and incubate new projects through hackathons and partnerships. With deep technical expertise, strong uptime performance, and a proven track record in community building, node101 is committed to decentralizing value at every layer of the blockchain ecosystem.

node101 prioritizes reliability and security across all validator operations. We run validators on bare-metal servers in Tier-III+ data centers (Cherry Servers, InterServer, OVH) with geographic redundancy. All systems are hardened with firewalls, intrusion detection, restricted SSH access, and regular patching.

Validator keys are never stored on validator machines; instead, we use remote signing with TMKMS / Horcrux and redundant key-signing servers.

Our 24/7 monitoring stack with Prometheus and Grafana includes automated alerting through PagerDuty and Telegram for downtime, slashing risks, and performance anomalies.

To ensure resilience, we maintain sentry and full node architecture with regular secure backups and fallback nodes. Clear incident response procedures allow us to act quickly, minimizing risks and ensuring high uptime.

Our core team of nine full-time developers and engineers brings expertise in blockchain engineering, cryptography, backend systems, and DevOps. Beyond infrastructure, we have a strong track record in building open-source tools (such as Klein for node operators), modular blockchain prototypes (Photon Bridge, zkVot, Orchave), and developer-focused applications.

We are also recognized as one of the leading blockchain event organizers in Türkiye and Paris, having hosted over 120 developer meetups, hackathons, and community events. This blend of technical rigor, ecosystem contributions, and community-building has positioned node101 as a trusted, long-term partner for protocols and delegators alike.
