Odaily Star Daily News: Bitcoin mining pool F2Pool admits to filtering transactions from Bitcoin addresses marked by the Office of Foreign Assets Control (OFAC). After Bitcoin developer @0xB10C discovered this, F2Pool co-founder Chun Wang acknowledged that his mining pool did use this filter, but after being questioned by the community, he stated that he would abandon the review until the community reached a more comprehensive consensus on this issue. The relevant posts have been deleted after investigation.

F2Pool, the third-largest Bitcoin mining pool, faced criticism on social media for allegedly censoring transactions from an address under US government sanctions. The controversy arose as many Bitcoin enthusiasts consider "censorship resistance" a fundamental principle of the blockchain. However, concerns have been raised by government officials worldwide that blockchain networks could be used to finance criminal activity and terrorism. F2Pool's decisions can have significant implications as they control a significant portion of the network's processing power.
