Coinbase has disclosed that it is the largest node operator on Ethereum, with 120,000 validators. In a new report, the exchange claimed it has 3.84 million ETH staked through its validators as of March 4, representing 11.42% of the total staked Ether.
The report, published to provide insights into Coinbase’s staking performance, stated that the company had an uptime of 99.75% in February 2025, which means that its validators were online and operational for 99.75% of the month. It noted that while it could target 99.9% uptime, it chose not to do so for security reasons.
By keeping the uptime above the 99% target but below the peak of 99.9%, the exchange claims that it has avoided security concerns such as double signing. Since its inception, it has never experienced double signing or slashing.
Slashing is a penalty in which Ethereum validators lose a percentage of their stake for committing infractions that affect network security. The slashed tokens usually go into Ethereum security.
It said:
“Targeting 99.9% requires security tradeoffs that can increase the risk of double signing resulting in slashing penalties. At Coinbase, high uptimes are important but we always prioritize the security of our customers’ assets over liveness.”
Meanwhile, the exchange noted that the higher-than-expected uptime in February is due to the upgrade in its architecture, which allows validators to keep operating even when maintenance is carried out on the beacon node.
Beyond the high uptime, the report also shows a relatively high participation rate of 99.75%. This metric captures the number of validators performing their consensus duty and exceeds the network average of 99.52%.
With Coinbase disclosing its stake in Ethereum, concerns about centralization on Ethereum have resurfaced. Although the exchange’s 11.42% stake is smaller than Lido’s, Coinbase is the biggest node operator, while Lido is a collective with smaller stakes for each node operator.
Some users, including Daily Gwei founder Anthony Sassano, have praised Coinbase’s transparency, while others note that it shows institutional commitment to ETH. However, most users focus on the size of the stake, which they believe makes Ethereum less censorship-resistant.
However, Coinbase addresses these concerns in its report, noting the diversity of its validators as proof that the network is still decentralized. The exchange claimed to have two consensus clients, two execution clients, and six relay clients.
The consensus clients are Lighthouse and Prysm, who account for 63.8% of the total network distribution. For the execution clients, Geth and Nethermind account for 79% of network distribution. This suggests that the Coinbase consensus and execution clients dominate the Ethereum network, likely because other validators also use them.
Nevertheless, the exchange noted its relay diversity, with six unique MEV relays, four of which are non-censoring, which has helped to reduce the risk of centralization while also avoiding a single point of failure and minimizing downtime. It acknowledged the risk of diversification and said there are plans to improve its client diversity.
It said:
“We are currently evaluating the production readiness of two more implementations and plan to continue expanding our client diversity.”
One area where the exchange appears to have more decentralization is the geographical location of its validators. Coinbase validators operate in five countries, including Singapore, Japan, Ireland, Hong Kong, and Germany, and there are also two cloud providers, Amazon Web Services and Google Cloud Platform.
