To be honest, this is not exclusive. We've been talking about this for a long time, but there are a lot of projects in Defi, and it's impossible to control everything. Many projects do not operate in the United States and are not required to adopt their regulations.
They will try to control Ethereum by rejecting transactions from sanctions lists, but these measures are not enough.
The news update might not be a recent news development, however, as members of the cryptospace community and as users of defi, we should always give the effort of making everyone know what is happening around the cryptospace, to be skeptical and to tell everyone our own thoughts or speculations on these occurences.
In DeFi projects, user identification is impossible, but only a whitelist of addresses is possible. Perhaps there will be companies that will get licenses and solve this problem.
I haven't seen any direct bans on DeFi in the US yet, and their tax regulations are quite ready for DeFi, although it will be difficult for users to keep records.
No, it is possible if we consider pancakeswap as an example of DeFi. The service is centralized because you need to visit
https://pancakeswap.finance. They can collect information about your addresses, and block the swap until you create an account. Then they can request more data after creating this account as KYC. It is true that they will not They do this now because they do not want to lose their user base, but they can do it gradually, such as making the KYC feature only for some airdrops or for tax regulations.
Unless the service is self-hosted like Bisq then restrictions can be imposed on it.
The frontend is centralized, however, the users can interact with their smart contracts directly through other methods very much similar to what occured with Tornado Cash.
