In fact, the ultimate question is: Does DeFi need to be decentralized?

Cold knowledge:

The ratio of public chain TVL to CEX is about 4:6, and the transaction volume is even worse, about 1:9.

I think the lending protocol is best decentralized, such as AAVE, because you feel more assured to deposit money in AVE, while it may be eaten up in CEX.

But is DEX necessary? At present, decentralized DEX cannot compare with CEX. The contradiction after the emergence of L2 is that L2 liquidity is not as good as L1, so the slippage is large.

The primary task of the public chain is to succeed in the field of DeFi, rather than doing something messy like SocialFi. As for NFT/Depin, it is just a way of issuing assets in a different way.

But has DeFi made any progress from 21 to now?

Uniswap has a new version, but CRV is dead, liquidity mining is dead, and the real income is ok.

The infrastructure required for defi is progressing very slowly, and cross-chain issues are a commonplace.
