Ethereum Network Monitoring

Ethereum is a programmable blockchain that uses proof of stake. ProbeLab crawls the discv5 network of the consensus layer to show client diversity, node locations, cloud hosting and support for upcoming forks. We also check the bootstrap nodes and measure block arrival times on GossipSub.

Core Statistics

Network structure in terms of client diversity.

Active Agents Distribution (24h)

Active Agents Distribution (24h)

Shows the client software (agent type) of the online peers. One value is the average number of online peers per crawl in the 24 hours up to the latest crawl. The six agent types with the most peers are shown separately. Other contains all other agent types. The percentages are shares of all online peers.

Our Nebula crawler gets the agent version of a peer through the libp2p identify protocol. Unknown contains the peers where this did not work, for example because the peer closed the connection before the protocol negotiation completed.

Data is provided as is, without warranty. Scraping and automated bulk extraction are not permitted. See our Terms of Use.

Cloud Distribution (24h)

Cloud Distribution (24h)

Shows how many online peers run in a cloud data center. One value is the average number of online peers per crawl in the 24 hours up to the latest crawl. A peer is in Cloud if ipregistry.co marks its IP address as a cloud provider address. All other peers are in Non-Cloud, also the peers without IP address data.

Select an agent type in the menu to see only its peers.

Fork Digest Over Time

Fork Digest Over Time

Shows the number of online nodes per fork digest over time, as the nodes announce in their node record (ENR). The fork digest identifies the fork that a node follows, so the chart shows how the nodes move to a new fork, for example from Electra to Fulu. Fulu BPO1 and Fulu BPO2 are the blob-parameter-only forks after Fulu. Only nodes with a known Ethereum mainnet fork digest are counted. The data comes from our Nebula crawls of the discv5 DHT, with one value per crawl, where one node is one IP address and port. Select an agent type to see only the nodes that run this client.

Next Fork Version Over Time

Next Fork Version Over Time

Shows the number of online nodes per next fork version over time, as the nodes announce in their node record (ENR). A node announces the version of the next fork that its software has scheduled. If no fork is scheduled, it announces the version of its current fork. So the chart shows how many nodes run software that is ready for an upcoming fork, for example Gloas. Only nodes with a known Ethereum mainnet fork digest are counted. The data comes from our Nebula crawls of the discv5 DHT, with one value per crawl, where one node is one IP address and port. Select an agent type to see only the nodes that run this client.
