29: State of the Mint and Mind w/ Calle

About this episode

Calle and Gigi discuss Cashu mint internals and embodied cognition, exploring various technical concepts and their implications for optimism in technology.

"You cannot look at something without touching it." Calle & Gigi take a walk. Listen on sovereignengineering.io Calle and Gigi start with Cashu mint internals and end in embodied cognition. Along the way they unpack sparse Merkle trees, exclusion proofs, unilateral exit, trusted execution environments, recovery paths, the move to BLS signatures, agentic coding workflows, specialist versus generalist models, world models, and why Bitcoin, Nostr, and local AI still feel like reasons for optimism. In this dialogue: how mint state can be compressed into a sparse Merkle tree and why exclusion proofs matter for ecash how unilateral exit could reduce both the slow rug pull and the fast rug pull for Cashu mints why trusted execution environments change the trust model, and why on-chain-first mint backing is the easiest place to start how timelocks and third-party recovery paths might soften mint downtime why Cashu is moving away from its current signature setup toward BLS signatures and what that unlocks how Calle actually works with coding agents, from OpenRouter and OpenCode to fresh contexts and ruthless resets why context windows are scarce, token maxing is wasteful, and one…
