@wagesj45 @suika the problem is that virtually *any* real use case makes blockchain properties pointless or outright undesirable.

A permanent receipt? Digital signatures already do that.

A ledger? It’s ultimately filled by humans, who make mistakes or outright lie. Which a blockchain, being append-only, cannot fix. Unless you append a correction, of course, but then you render the entire concept moot.

An NFT? It’s neither necessary nor sufficient to enforce copyright.

Etc.
