There is no shortage of the news on stablecoin censorship, in particular blacklisting of Ethereum addresses:
Tether has been blacklisting Ethereum addresses that hold USDT for a couple of years now—this year alone, Tether has blacklisted 24 addresses that hold a total of $5.51 million USDT in summation. [...] Tether has blacklisted a total of 39 out of the 1.47 million Tether addresses that exist, which represents a total of 0.00002% of all tether addresses. When a tether address is blacklisted, it can’t send, receive, or redeem USDT.
Assuming that the said stablecoin issuers are not miners/validators, how are they able to do censor sending and receiving? Does such censorship involve also NFTs, Eth, and other erc-20 tokens? Could similar censorship be done by MakerDao?
