Cashu is, AFAIK, the only chaumian ecash implementation that is “live” on bitcoin/lightning. Fedi (the for-profit entity working on the FOSS Fedimint protocol) says they’ll ship something this quarter sometime.
Cashu, being live, lets us play with chaumian ecash on bitcoin. It gets me more excited about chaumian ecash than just talking about something that might come…
I've been using the Fluttermint client half a year ago on mainnet, cashu came later.
I don't know what came before but I just checked my calendar and and I can say for certain that I coded up the first Cashu version between Sept. 9-11.
Since then, we're live on mainnet 🤙
Fluttermint was there for HCPP22, that was first October weekend, so it seems that cashu was first on mainnet after all.
Reckless!
