Ukrainian Finance Minister said the government is in position "to block crypto wallets" containing " illegally obtained crypto assets" . (I wonder how to?) .

They are going to ask crypto exchanges and banks to do KYC of people who do operations with crypto past certain limit - around $1,200, and they will have to report "suspicious" transactions and regulators might order to freeze assets on those online accounts. They also talk how they will be using chain analysis to do their verifications.
Also, there's another interesting line that wasn't in the article - the minister said that they don't see crypto being used by corrupt officials, so it should be legalized in long term to boost economy.
