According to Cointelegraph, in order to alleviate the impact of "Black Thursday", MakerDAO's practice of using USDC as a collateral triggered a dispute over centralized guaranteed assets. In this regard, Rune Christensen, CEO of the Maker Foundation, said in an interview that he supports providing centralized guarantees for DAI. What is important in this discussion is the Maker agreement and general DeFi products, as well as creating real value and use in the real world. The most important thing is not ideology. In Rune Christensen's view, the choice of good collateral is risk management, and concentrated assets and dispersed assets will bring risks. Centralized assets such as USDC may face risks such as the issuer's right to freeze funds, but Christensen emphasized that decentralization, that is, the dispersion of assets also has its own risks, that is, volatility risks. He said that it was like there was Ethereum first, followed by a relatively concentrated stable asset, or generally speculative crypto assets and tokenized fiat, although it seems that they are on opposite ends of the risk spectrum, but In fact, the two assets are complementary. In addition, Christensen said that relying on only one stable currency is not ideal, but it is clear that spreading the risk to five different stable currencies is the next step.
