The Institutional Compliance Stack for Validator Operators in 2026

ISO 27001 is the floor. SOC 2 Type II is the institutional bar. MiCA CASP is the European operating licence. Pen-tests, bug bounty, DPA, MSA, SLA — the full stack of compliance evidence that institutional counterparties now ask for, what each one actually costs to obtain, and what 01node has, what is in progress, and what is planned.

Slashing Economics: The Real Cost of a Validator Mistake

A slashing event is not just a percentage of stake burned. It is the loss of all delegators who can leave, the reputation hit that compounds for years, the trust pack page that needs an asterisk forever. We work through the math — chain by chain, dollar by dollar — of what it actually costs an operator and a delegator when slashing happens.

DVT Explained: Obol vs. SSV vs. Diva — How Distributed Validator Technology Actually Works

The 2-of-3 cluster, the 4-of-7 mesh, the threshold signature scheme that makes a single operator compromise meaningless. We break down what Distributed Validator Technology is, how Obol Charon and SSV Network differ structurally, where Diva fits, and why Lido is now running its institutional staking pool through DVT clusters.

The Complete Guide to Validator Operations in 2026

Why a Validator Is Not a Server

Five years ago a validator was a server. Today it is a cluster of signers, and the math is the entire reason solo operators still slash themselves. A focused walk-through of the 2/3 signing architecture, the slashing-protection check that runs before every block, and the key-sharding property that makes a single compromised node useless.

On Validator Setup: Seven Years Later

In June 2019 we published our validator architecture on Medium — YubiHSM dual-DC, VPN-only access, sentries per network. Seven years, forty mainnets, and zero slashing events later, here is what we kept, what we changed, and what we would do differently if we started today.
