System status:

Notes: We run a node that connects to and interacts with the Bitcoin network. It spiders and attempts to make connections to every reachable node. It's similar to, which also periodically harvests data from Bitcoin network and publishes the data. Our node is distinguished by the version string "UMD-Coinscope".

Our network topology inference technique makes use of behavior specific to Bitcoin Core prior to version 0.10.1.
