Does pegging crypto to SDR (instead of stable coins) make any difference?

[Galley]

I am into investing DeFi rather than just Bitcoin and Ethereum. DeFi space amuse me with its incredible capability of solving real-world problems. So, I regularly research and invest in DeFi projects. So today, I heard of new term known as "SDR". Created by IMF, it is basically combination of five well-established fiat currencies - the U.S. dollar, the Euro, the Chinese renminbi, the Japanese yen, and the British pound sterling. So, pegging certain crypto coins with SDR instead of stablecoins like USDT, USDC or DAI makes any different?

Let's discuss!

The information presented, in my opinion, is not enough to draw certain conclusions. If the term "SDR" means only the aggregate of the five major currencies of the world - the US dollar, the euro, the Chinese yuan, the Japanese yen and the British pound sterling, and is not exposed in some new shell, then this, in fact, does not change anything. Cryptocurrency is already equated to each of these currencies. Stablecoin is just a shell for fiat, and what is SDR is a little unclear.

I also do not really understand what these innovations are for. In fact, the cryptocurrency is focused on pegging to the US dollar, and the rest are already playing from quotes to the dollar. What else can you think of here?
