Celestia Network Monitoring

Celestia is a modular network that provides data availability for rollups and other blockchains. ProbeLab crawls the network to show which clients the nodes run, where they are and which transports they support, and counts the light clients behind NATs. We also check the bootstrap nodes and the DHT keyspace for signs of Sybil and eclipse attacks.

Peers By City

This map shows the online peers per city in the last crawl of the latest day. The city and its coordinates come from the IP address mapping of ipregistry.co. Peers without a known city are not on the map. The text below the map shows how many peers are not on the map.

Client Diversity Trend

Client Diversity Trend

Shows the evolution of different user agent types (client software) participating in the network, over time.

Each agent type represents a different implementation and and indicates its relative prevalence within the network for the given reporting period. This chart helps track software diversity, adoption of new client versions, and overall network health, in terms of active nodes in the network.

The Unknown category represents nodes where the agent version could not be retrieved through the libp2p identify protocol. This situation can occur due to various reasons, such as the node terminating the connection before completing the full protocol negotiation.

Light Client Population

Data from our Ants measurement setup. Ants also finds the light clients that run behind Network Address Translators (NATs), not only the server nodes.
