Proof of Reserves is the new gold standard. The excuses don't cut it anymore. It's time for everyone to demand transparency from their custodians and move the industry forward. https://river.com/reserves

We’re saying only 15% self custody, about half the amount of people who make any sort of onchain tx

We are entering an era where both #Bitcoin and USD will play key roles in the average American's financial life. The coming years will see a fascinating interplay between Gresham's law, fiat protocol stickiness, and geopolitics. Hang on tight.

Totally understandable. We are working hard to get ACH hold times down. If you purchase a large about of BTC via bank wire you can withdraw immediately FYI

ACH holding periods. Most clients don’t see more than 5 days. ACH is a very reversible payment rail unfortunately. It’s all risk based. Long term clients have very short holding periods

I’ve heard people arguing that DIDs are better than the email address format used by LNURL because they don’t require DNS. Is that not a point DID proponents are trying to make?

2023-01-22 01:52:40

- reply

I get that but DIDs look ugly and are bad UX so you still need DNS for a global human readable namespace to provide decent cross-app UX. So is DID just an incremental upgrade to a raw pubkey?

2023-01-22 01:40:09

- reply

Why is it not just a no-man’s land between dns based human readable addresses and pubkeys? How can you have a universal elegant-human readable identifier without DNS?

2023-01-22 01:16:54

after reading the DID spec I’m bearish on the UX. did:nostr:randomkey is very unaesthetic and the lnurl email lookalike format seems much more reasonable despite the dns requirement. tell me why I’m wrong.
