    CD200: UTXO - WISP - BETTER NOSTR

    UTXO The Webmaster joins to discuss his new android nostr client Wisp, spark wallet integration, encrypted nsec seed backups, and his controversial "Send Money" normie mode that denominates zaps in dollars.

    CD199: CRAIG RAW - SILENT PAYMENTS AND SPARROW WALLET

    Craig Raw, creator of Sparrow Wallet, joins to discuss silent payments, a new bitcoin address system that eliminates address reuse, removes the gap limit, and aligns privacy with convenience. Craig walks us through the history of bitcoin address derivation from single key to hd wallets to bip 47, then explains how silent payments optimizes everything except scanning cost and how his new server implementation, Frigate, uses gpu acceleration to mitigate that. We discuss the path to adoption including hardware wallet support, public server infrastructure, bip 353 human readable addresses, and the overall vision of upgrading from hd wallets to sp wallets.
