Marathon, one of the biggest bitcoin mining dedicated companies in the U.S. and Canada, has mined the first OFAC compliant bitcoin block, only accepting transactions that comply with the directives of this government office. This has caused a stir in libertarian circles, that argue this can be the start of censorship in the bitcoin blockchain at a mining level.

"Marathon is committed to the core tenets of the Bitcoin community, including decentralization, inclusion, and no censorship," said Marathon's CEO Fred Thiel. "Over the coming week, we will be updating all our miners to the full standard Bitcoin core 0.21.1 node, including support for Taproot. By adopting the full standard Bitcoin core node, we will be validating transactions on the blockchain in the exact same way as all other miners who use the standard node."
