PANews reported on August 27 that Sam MacPherson, CEO of Phoenix Labs and Spark Protocol, revealed that USDS after DAI upgrade will add a freezing function, similar to centralized stablecoins such as USDT and USDC. At the same time, MakerDao's upgraded Sky official website is suspected to block some regions on the front end and prohibit the use of VPN login. However, MacPherson deleted the message 30 minutes later.
