About this episode

Craig Raw discusses silent payments and the Sparrow Wallet, exploring the evolution of bitcoin address systems and their implications for privacy and convenience.

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.
