Is interop finally solved? In this episode of Deeply Intents I chat with Isaac Sheff (Senior Research Scientist) and Christopher Goes (o-founder) of Heliax about the Anoma protocol and explore how Anoma thinks about interop. In particular we discuss Isaac's research on Controllers [the authoritative state machine that orders transactions for a resource, preventing double-spends]. We begin the episode discussing Isaac's background as a consensus researcher and his prior work on Heterogeneous Paxos. We then dive into controllers and compare them to IBC, and discuss we you need different trust models for blockchains, databases, and computers. Thereafter the episode gets quite technical as we discuss the nuances of Anoma's resource model, controller tags, and next concepts called shared & causal resource history. Next we explore how controllers utilize ZK proofs for tag reduction and attestation. Finally we discuss the novel emergency override condition which one can think of as a generalization of Plasma (Ethereum), how controllers unlock private bridging, and the affordances they provide application builders who want to build distributed applications.
