Our Security
Running validator infrastructure requires discipline, operational experience, and a strong focus on security. At Staker Space, we build security into every layer of our operation, from infrastructure and key management to monitoring, upgrades, backups, and incident response.
This page describes how we operate today and the practices we use to keep our validator infrastructure reliable and secure. We aim to be transparent about our processes, specific where possible, and straightforward in how we operate. You can also view the current health of our public services on our status page.
How Our Infrastructure Is Set Up
Dedicated Infrastructure
Each validator we operate runs on dedicated infrastructure that is not shared with unrelated workloads. Only the network ports required for validator operations are exposed to the public internet, while management access is restricted through SSH key-based authentication and limited to authorized operators.
Secure Key Management
Where supported by the network, we keep high-value withdrawal and staking keys offline and separate them from the validator infrastructure. The validator only has access to the keys required for its day-to-day operation, reducing the impact of a potential compromise.
Monitoring & Alerting
All validators are continuously monitored for availability, network connectivity, synchronization status, and overall performance. Alerts are sent directly to both operators, allowing us to respond quickly to issues before they impact validator operations.
Our Security Practices
Timely Client Upgrades
We actively track software releases and network upgrade schedules across the protocols we support. Regular updates are applied in a timely manner, while major network upgrades and forks are carefully planned, tested where possible, and coordinated according to network requirements.
Backups & Recovery
Critical validator data, including keys and network-specific protection databases where applicable, is backed up to encrypted off-site storage. Recovery procedures are periodically tested to ensure systems can be restored efficiently if needed.
Small Team, Clear Ownership
Staker Space is operated by two experienced operators. This allows us to maintain direct oversight of our infrastructure, limit access to critical systems, and respond quickly when action is required.
Operational Discipline
Reliable validator operations depend on more than infrastructure alone. We follow established procedures for upgrades, maintenance, and operational changes to help ensure consistency and reliability across the networks we support.
Security Through Decentralization
We believe that a strong Proof-of-Stake network depends on decentralization. By supporting independent validators like Staker Space, delegators help distribute stake across a broader set of operators rather than concentrating it among a small number of large providers.
