Bitcoin node software versions
User agents reported during successful handshakes. These strings describe reachable observations and can be customized or spoofed; they do not establish software integrity, voting power or consensus support.

Latest observation or check: . This is a dataset activity timestamp, not the check time of every row.
Reading version distribution
A node may report a familiar software name while using a modified build. Addresses also do not correspond one-to-one with independent operators. This table is an observation of protocol strings, not a count of people choosing a policy.
Unknown strings stay in the denominator. Selecting a user agent opens the reachable node list with a text filter; text searches may also match longer strings. No individual user-agent pages are generated.
An observed view from our crawler's vantage point, not a complete census. Reachable means a successful Bitcoin P2P handshake. IP geolocation is approximate. How Atlas measures the network.
