Vitalik Buterin, the founder of Ethereum, said in the Chinese community that he is optimistic about rDai's direction and provides financial support for blockchain projects by locking coins. He said, "This (rDai) is a lock mode, not a coin. Since there is no possibility of loss if you do not insert a coin, this model also has legal advantages." Developed to tokenize the ownership of interest generated by pledged cDAI. cDAI is a new feature of Compound v2. Users who loan Dai on the Compound platform can obtain Compound Dai (cDAI), which represents the principal plus interest after the user deposits Dai.
