In this episode of Bullish on Bitcoin Show, Alexei sits down with Jacob Phillips, co-founder of Lombard and former investor at Polychain, to tackle the big question: is Bitcoin DeFi dead or alive? Jacob brings a rare DeFi-native perspective on Bitcoin, having entered the space chasing the multi-trillion-dollar opportunity of idle BTC capital rather than as a lifelong Bitcoiner. From the rise and fall of the Bitcoin staking boom, to why "productive Bitcoin" was already a reality off-chain long before DeFi existed, to the hard truths about custody, risk, and yield — this conversation is a candid post-mortem and forward-looking roadmap for where Bitcoin DeFi goes from here, including a first look at the upcoming LBTC Phase 2.
