Yes, Tether is nothing more than a weird bank. USDT is backed by real currency (or atleast Tether claims so). And is equivalent of the treasury giving you a bill and promising to pay you, just on a pollution causing blockchain

But see how nice having a blacklist is (which you seem to say is the core business of banks, when in fact it is to provide massive amount of capital as loans at a cost or create yield-producing aggregated products - which can work with any currency, crypto or not, and which Tether barely fits the definition of).

I d propose every chain to have a blacklist mechanism, temporary if you want, with a voting mechanism to remove innocents. You cant facebook your way ("we re just a platform") out of financial rules or you ll just end up rewarding thieves while benefitting innocents very little.

To be fair, they never claimed to be anything else, just a conduit to allow seamless transfers of usd value on the blockchain, while they hold the actual funds (applies to all non-algorithmic stables).

It is more like a regular bank than anything else. A bank that uses a different transport network.

That's why decentralized stable coins like DAI and others exist :)
