Polkadot Network Monitoring

Polkadot is a network of connected blockchains (parachains) that share the security of one relay chain. ProbeLab crawls its peer-to-peer network to show which clients the nodes run, where they are and how long they stay online. We also check the bootstrap nodes.

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.
