Researchers Find Bitcoin Network 3X More ‘Evil’ Than the Public Internet

Just recently a research group called Rapid7 published a report that reveals over a year’s worth of research regarding malicious activity tethered to Bitcoin Core (BTC) full nodes. By utilizing data collected from a network called ‘Project Heisenberg,’ and its internet scanner ‘Project Sonar,’ alongside intelligence from Bitnodes, the team had found quite a lot of exploits being shared between full blockchain nodes.

Bitcoin full node operators connect usually connect by default to a TCP service on port 8,333, but there are also over 600 alternative ports available. Rapid7’s recent research used data from the team’s Project Sonar which revealed the top three countries with the most port 8,333 nodes stem from the U.S., China, and Germany. The researchers began the blockchain surveillance back in August of 2017 and found more than 11,000 nodes per day. Moreover, the researchers collected data from more than 144,000 unique full nodes during the course of the study.
