F2Pool, a prominent Asian Bitcoin mining pool, appears to be enforcing U.S. sanctions by selectively filtering transactions from wallets identified on the OFAC blacklist.

After analyzing four transactions under sanctions that F2Pool had not processed, Bitcoin developer 0xB10C surmised that their exclusion was likely intentional. This is based on the understanding that mining pools have the discretion to pick and choose the transactions they wish to process.

"The Bitcoin network, however, continues to work as normal. A single pool filtering transactions does not compromise the overall censorship resistance of the Bitcoin network," the developer points out.

Yet, since all these transactions were from a single wallet, it remains uncertain if F2Pool is systematically avoiding transactions from specific wallets or if this was an isolated case.
