CD209: MATTHEW VUK - BARK - BITCOIN PAYMENTS ON ARK

Matthew Vuk joins to discuss Bark, Second’s Bitcoin-only implementation of the Ark protocol. We get into how Ark wallets enable Lightning, on-chain, and instant Ark payments without managing channels or liquidity, plus VTXOs, delegated refreshes, unilateral exits, cloud backups, fees, privacy, and denial-of-service protections. Then we discuss running Ark servers, using Bark to power Cashu mints and African mobile-money gateways, proof of reserves, comparisons with Spark and Arkade, and Second’s mission to build open-source Bitcoin payment infrastructure.
