The scan used a modified version of virtu’s p2p-crawler which connects to every node, waits up to three minutes for a FEEFILTER message, and records the result. If no FEEFILTER message is received within the timeout the node is listed as “No FEEFILTER sent.” Only nodes that… ## [Fingerprinting nodes via addr requests](https://danielabrozzoni.com/posts/addr_fingerprinting/) _2025-06-23 · Daniela Brozzoni_ This blog post comes from the research of @naiyoma and me. It is currently possible to identify nodes running on multiple networks by analyzing their ADDR responses. Below, we’ll share highlights from our attack attempts - while deliberately avoiding too much detail about the methodology - and discuss some possible solutions. This fingerprint attack can hurt network privacy and enable more…
