You’re being downvoted because you’re making sweeping unsupported assertions, likely based on an ideological opposition to blockhain.

I am guessing it has to do with anger at FTX and other negligent participants in the wider “crypto” ecosystem that has very little to do with blockchains. But that is a “non sequitur” (Latin for “it does not follow).

If I am wrong in my assumptions and you have an actual argument supporting your assertions about “all blockchains” being crap, please do elaborate on the substance.
