$ETH U.S. agency OFAC sanctions Tornado anonymous mixing service, over 70% of validators actively participated in the review... bowing to state level pressure. The latter part may refer to the slow development of rollups, the slow resolution of layer 2 fragmentation, and delays in POS staking withdrawals. What happened? In 2022, after the U.S. government imposed sanctions on Tornado Cash (a privacy mixing tool on Ethereum), some MEV relays (Maximal Extractable Value relays) and validators began to actively exclude transactions interacting with Tornado Cash contracts to avoid violating U.S. law. This raised concerns in the community because: some validators actively reviewed certain transactions; over 70% of blocks at the time were packaged by relays compliant with OFAC requirements; this goes against the principles of decentralization and neutrality, and Ethereum has become influenced by the U.S. government.
