How we run validators

Hardware

Every validator runs on a dedicated bare-metal server in a data centre in Europe or North America, administered by us. We do not run validators on shared cloud instances: the disk, the memory and the network port are ours alone, and nobody else's workload can slow a block. The public endpoints and the node docs run on the same servers.

Keys and signing

A validator sits behind sentry nodes, so the machine that signs is never the one that peers with the public network. It signs through a remote signer: the consensus key lives on a machine of its own, and the validator asks it for each signature. Double signing is what gets a validator tombstoned, and the figure is read from the chains, the same one the About page shows and in the same words: as of 12 Oct 2026, 0 double-sign events, not tombstoned on any Cosmos chain.

Monitoring

Every validator and endpoint reports to our monitoring tools, and missed blocks raise an alert. A collector of ours reads our validators' state from the chains every minute, and every live figure on this site (signed blocks, rank, voting power, the chain's height) is read from its output. The Networks page shows the current figures for each network; the network page shows the signed blocks of the last window.

Upgrades and governance

We follow each chain's upgrade proposals and publish the procedure we use in the node docs, with a snapshot and state-sync parameters where the chain supports them, so another operator can do the same. Every governance vote our validator casts is listed on the Governance page with a link to the proposal.

When something goes wrong

A validator that misses too many blocks in a chain's slashing window is jailed and slashed by the chain. If downtime on our side ever causes a slash, we refund the slashed amount to the affected delegators in full. Our validator on Lumera states it in its on-chain description. The refund policy is on the About page.

Where we validate

Mainnets: Arkeo, AtomOne, Avail, Bitway, Cosmos Hub, BlockX, CrossFi, Epix, Lumera and Uptick. Testnets: AtomOne, La Tanda and Lumera. We join a new network at genesis or on its testnet, free of charge; the Networks page lists each one with its live figures.
