F2pool acknowledged filtering transactions involving addresses under OFAC sanctions and stated it would suspend the filtering after being questioned by the community
ChainCatcher news, Bitcoin mining pool F2Pool has acknowledged filtering transactions from Bitcoin addresses marked by the Office of Foreign Assets Control (OFAC). After Bitcoin developer @0xB10C discovered this situation, F2Pool co-founder Wang Chun admitted that his mining pool is indeed using this filter.
In addition, Wang Chun explained in a post about why the filter is used that he has the right not to confirm certain transactions and must design an "anti-censorship system" to resist censorship from the protocol design level, rather than relying on each participant to decide not to censor. He explained that Bitcoin should learn from the experiences of the internet in this regard. However, after this statement was questioned by the community, Wang Chun announced that he would temporarily stop filtering these transactions until the community reaches a new consensus.
According to previous reports from ChainCatcher, Bitcoin developer 0xB10C stated that six transactions from OFAC-sanctioned addresses were recently detected as not being mined by certain mining pools, which may indicate that these transactions were intentionally filtered.
