美国制裁与区块链审查：以太坊网络在OFAC规定下的交易筛选现状

According to the data of and, since Ethereum changed from workload certificate to equity certificate on,, about some blocks in the Ethereum blockchain have reviewed the wallet addresses included in the specially designated national list of the Overseas Assets Control Office of the US Treasury Department. In other words, these blocks will exclude or prevent the transactions of wallet addresses appearing on the US sanctions list when dealing with transactions, and the proportion of blocks that carried out this review earlier this week is even close to this, which means that it is in Ethereum. About half of the blocks in the network are carrying out some form of transaction review according to the US sanctions list, which is different from the unlicensed encrypted network such as Bitcoin. The compliant relay nodes in the Ethereum have tried to find out the maximum extracted value tools from the wallet addresses on the US sanctions list. By default, they will review these wallets. Many relay nodes use their default settings and outsource the production of the verifier's blocks to the third-party market operated by themselves. After pre-transaction, Set quantitative trading strategies such as transaction attack trading to maximize revenue. These strategies may make use of some examples of relay nodes of ordinary Ethereum users, including the largest so far, and so on. This means that when the nodes responsible for disseminating transactions and block information using software handle transactions, they will automatically filter out those transactions with wallet addresses listed as specially designated national lists by the United States, so the transactions at these addresses will not be included in the blockchain. Many relay nodes can. Can choose the default settings to use so as to implement this review mechanism in their operations. The picture will be reviewed by the relay operators who provide compliance with US sanctions, which users can broadcast transactions on the Ethereum blockchain. Of course, those users who are sanctioned by the Overseas Assets Control Office of the US Treasury Department can still try to execute their transactions through other non-compliant channels even if they cannot follow the prescribed path, such as some cryptocurrency exchanges or verification nodes. In other words, These users may look for trading platforms or network nodes that don't follow the sanctions regulations to complete their blockchain transactions, because these platforms or nodes will not filter or reject transactions according to the sanctions list. For example, last year, they were sanctioned by the US government for providing mixed currency services to North Korea, but in the past two weeks, according to the data, they verified a related transaction and confirmed and added these transactions to the blockchain as a verification node of Ethereum Network. This table shows each verification. How many pieces have been put forward by the witness, including the transaction sources that have interacted with all denominations of contracts or wave fields, which is a bit embarrassing for me. It seems that he has turned a blind eye to the behavior, but these contract interactions are clearly visible in the chain. It is estimated that sooner or later, he will have to face this problem and make a decision, which is also a relatively great potential impact on Ethereum. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
