435: Confidential Finance: The Last Mile Problem Web3 Must Solve with Guest Speaker Howard Wu from Aleo

EPISODE DESCRIPTION  I sat down with Howard at Token 2049 in 2026 to dig into one of the most overlooked problems in crypto right now: the complete lack of financial privacy on public blockchains. Howard is the founder of Aleo, the team behind Shield , a privacy-first multi-asset wallet and confidential AMM. We go deep on why on-chain transparency is a genuine security risk for everyday users, why institutions absolutely cannot operate without confidential finance, and how Aleo's approach differs from the cypherpunk-style privacy coins of the past. Howard breaks down how zero-knowledge proof technology has evolved from taking three minutes on a MacBook to three seconds on an iPhone, why compliance and privacy are not opposites, and what confidential finance means for the next wave of RWAs, stablecoin payments, and AI agents trading on-chain. This is a conversation I think anyone building or investing in Web3 needs to hear.  DISCLAIMER Nothing mentioned in this podcast is investment advice and please do your own research.
