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. ⚖️
