Vero v1
It’s been over a year since we began running early versions of Vero on the Holešky public testnet. Today, we're excited to announce a major milestone: Vero v1.0.0 is officially here, production‑ready and built with support for the upcoming Pectra network upgrade.
What is Vero–and why should you care?
At its core, Vero is a multi-node validator client designed to make staking safer. It helps mitigate the risks caused by client bugs like those behind the recent Holešky testnet incident where inconsistent client configurations led to an incorrect version of the chain getting justified.
Vero combines data from multiple client implementations, only attesting to the latest state of the chain when there is consensus across them. It’s like having a second (or third) opinion before making critical decisions on-chain.
Why Vero matters for professional node operators
If you're running validators professionally, Vero gives you granular control. You can:
Run diverse combinations of consensus and execution clients.
Define exactly when validators should or shouldn’t attest.
Significantly reduce the risk of slashing due to client bugs.
At Serenita, for example, we use Vero to combine data from 5 different CL client implementations and 4 different EL client implementations! With our current configuration all of our managed validators are completely safe from bugs in any single client, and we plan to reduce risk even further.
Vero also comes with:
Detailed tracing data
Dig deep into how and why certain actions occurred—for example, why a block proposal was missed. Perfect for debugging and transparency.
Slashing detection
If any managed validator gets slashed, Vero halts all validator duties immediately. This automatic response prevents further slashings in case of a setup misconfiguration.
Keymanager API (coming in v1.1)
This feature will let you manage validator settings more efficiently.
What about home stakers?
Even if you're staking from home, Vero can make a difference. While running a large set of client combinations may not be feasible, many home stakers already have a primary node and a fallback. With Vero, your validator can use both: cross-checking the chain state before attesting and greatly reducing the risk of landing on the wrong version of the chain.
eth-docker now has support for Vero and is the easiest way to try out a multi-client setup!
Note to (re)staking protocols
Staking and restaking protocols form a big part of Ethereum today. We encourage these protocols to require client-diverse multi-node setups for validators under their umbrella in order to minimize risk, protect their users and help improve the network's resilience.
