2025-05-28 12:55:47 UTC

Nostr MLS is here!
A HUGE step forward. 💪
But before you start using #nostr for sensitive Bitcoin actions, take warning from @nprofile…6yw7 - encrypted or not, nostr messages live forever on servers you don’t control.
(Oh, and not to mention future post-quantum threats!)
[BR096]

2025-05-16 17:39:45 UTC

The OP_RETURN debate may be distracting from a far more existential threat to #Bitcoin.
The Samourai Wallet case could set precedent on whether node operation is legal in the US. ⚖️

Is Cashu an L2 or an L3?
While this may be debated (and @nprofile…pfx4 might disagree!), @nprofile…dg6s and @nprofile…9l3k argue that #Cashu is the "perfect L3" - generally using lightning for settlement, whilst offering a different trust model and features. [BR095]
