The fact that web3 has been completely falsified does not mean that these infrastructure projects do not exist or are unnecessary, but that those that are closer to serving the needs of the D-field are more valuable, and those that are farther away are not.
In fact, there is a little bit of this meaning at present:
Exchanges provide venues
Public chains provide on-chain venues
Pumpfun, bananagun
Currently, the ones that occupy the front row of attention and mind are mainly around memecoin
It is not necessarily a bad thing.
