Bitcoin developer @uxerik_ builds prototype of a fully functional Bitchat Cashu wallet on Android. Bitchat is the new Bluetooth messaging protocol the founder of Twitter @Jack Dorsey released last week that does not need internet or cell service.
#Bitcoin dev @uxerik_ just built a working Bitchat wallet on Android, no internet, no cell service, just peer-to-peer Bluetooth payments.
Aggregate signatures are the cryptographic requirement for cross-input signature aggregation (CISA) @n1ckler joined us to talk about DahLIAS, a scheme that does exactly that
Jonas Nick (@n1ckler) joined Brink engineers to discuss the DahLIAS interactive aggregate signature scheme: - DahLIAS overview - Secp256k1 compatibility - DahLIAS vs FROST/MuSig2 - Interactivity requirements - Cross-input signature aggregation (CISA) - Key tweaking - Q&A
#Bitcoin en entornos caóticos no es una teoría, es una realidad, y te lo cuento en este vídeo @CashuBTC @libdesatoshi
