Reliable Validator Operations & Linux Infrastructure

We operate and maintain validator servers for decentralized networks (Cardano), with a focus on uptime, security, and transparent operations. Our revenue is protocol rewards for infrastructure provision — not financial intermediation.

About Us

Saruta Genesis Limited is a technology firm focused on blockchain validator operations, Linux server administration, and lightweight web systems. We have operated Cardano validator pools since the early testnet phase and continue to contribute infrastructure to a top-tier public blockchain by market capitalization.

Our approach is pragmatic and security-first: automated monitoring, hardened SSH policies, and reproducible server builds. We do not manage third-party funds and do not provide exchange or custodial services.
