Your Money, Your Data, Your Mind | Jesse Posner

“If somebody gets control over your personal AI — all your health data, all your financial data, all your emails, everything you've thought about — they own you.” Jesse Posner built FROST threshold signatures and shipped BitKey at Block. Now he's building Vora because he realized individual self-custody is still a LARP — and the stakes are about to get much higher. Episode Summary Most people think a hardware wallet means they've solved self-custody. Jesse Posner spent years at Coinbase and Block learning exactly why that's wrong. Without a full node, your wallet leaks your balance and IP address to third-party servers. Without physical security integration, your keys are one wrench attack away from worthless. Without verifiable hardware, your entire setup might be compromised from the factory floor. Vora is building the integrated answer: a sovereign device combining a full Bitcoin node, air-gapped hardware wallet, tamper detection, and emergency response — all designed so that attacking a Bitcoiner becomes more expensive than it's worth. But Posner isn't stopping at money. He argues the next frontier of self-custody is your mind. As personal AI agents accumulate our most intimate data — health records, financial decisions, private thoughts — whoever controls that AI controls the person. Vora's “guardian AI” architecture uses hardware-backed isolation to guarantee that no prompt injection can reach your most trusted model, while still letting you harness frontier cloud models for non-sensitive tasks. The same cypherpunk principles that protect Bitcoin keys now protect the most valuable asset of all: your autonomy. About the Guest Jesse Posner is CEO and co-founder of Vora, a startup building Bitcoin-grade self-custody for both digital assets and AI. A trained lawyer turned cryptographic engineer, Posner spent over four years at Coinbase on key management, then helped build BitKey at Block. He created the first BIP-340 compatible implementation of FROST (Flexible Round-Optimized Schnorr Threshold Signatures), supported by a Brink grant. His work sits at the intersection of cryptography, constitutional law, and physical security — bringing an unusually broad lens to the question of individual sovereignty in the digital age.
