The story of #cashu and #fedimint is a textbook example of why user experience beats technical superiority every time. People developing around nostr really need to keep this front and center. A lot of gains have been made in this area in the past year, but nostr is still difficult to use even for technically adept people.
Cashu won not because it was technically superior but because it was easier to use both for users and developers who wanted to build tools that leveraged Cashu. I see Cashu everywhere, Fedimint is basically non-existent.
Cashu is a custodial way of storing BTC which exposes uses to significant risks of being deliberately rugged, having their mint hacked, or having their mint just randomly go offline one day forever. Fedimint mostly solved this by having coins locked up among multiple mints, now these bad eventualities required cooperation between multiple parties.
But at this point, fedimint is looking more and more like a footnote in #Bitcoin development history.
