Running Holesky validators at scale on testnet
To build experience running Ethereum validators at scale, and to experiment with our new Sao Paolo location, we activated 1,000 validators on Ethereum’s new Holesky testnet. So far, our performance ranks us in the top 15% of validators on the network. More to come!

Expanding geographic decentralization with Latitude.sh
Originally committed to running on-prem machines, we realized that our “home” data center near Frankfurt, Germany was limiting our ability to offer geographic decentralization. We’re now running Ethereum testnet infrastructure out of the Sao Paolo data center of Latitude.sh, who have additional locations throughout South American, Europe, and Asia.

Sui mainnet launch
Running a validator during the mainnet launch of Sui was a big moment for H2O Nodes – our first mainnet launch of a major L1 blockchain! We are overjoyed to have the opportunity, and committed to demonstrating great performance on an ongoing basis.

Lido DVT testing
After many months of running Obol’s first testnet DVT cluster, we joined another cluster as part of Lido’s 2nd round of DVT-testing efforts. This time, the cluster has 10 participants. (and Lido is organizing 10 clusters!) We’re very impressed with the progress that the Obol team is making.

Public Solana validator reaches top-10 rank on StakeWiz.com
Reaching the top-10 rank on StakeWiz was a sign that we’ve achieved what we set out to do: run a high performing validator out of a minority datacenter, in order to increase the decentralization of the Solana network.

Public Solana validator receives Marinade stake
After migrating to v2 of Lido on Solana, we were able to run a public validator on Solana for the first time. A number of epochs later, Marinade’s delegation strategy began to delegate to our high-performing validator.

Ranked “Absolute top” on Rated.Network, running MEV Boost on Ethereum
With 99% effectiveness, Rated Network ranks our validator at the “Absolute Top”. With most of the Ethereum validators already running MEV Boost, we joined the party and began running MEV Boost, using the flashbots relay.

Lido onboarding brings us onto Solana mainnet
We were onboarded to Lido on Solana during the third onboarding wave. Until then, we had only run on testnet due to the non-trivial voting costs associated with running a mainnet Solana validator. We’re very grateful to Lido for giving us the chance to stake their delegation given our lack of history up to that point, and we didn’t let them down.

Company formation, Solana testnet, Ethereum beaconchain
After forming our team and putting the company founding process in motion, it was time to see whether we could achieve higher performance on Solana testnet, Ethereum testnet, and eventually also Ethereum mainnet. We had a lot to learn, but each obstacle taught us more about the networks and best practices.
