Hey HNI'm the author of Jido, an Elixir Actor & Agent SDK. I was building out an Elixir Durable Actor/Agent server and hit a wall regarding communication protocols. I reviewed all the existing protocols; A2A, ACP, AHP and nothing met my needs.I wanted a language agnostic durable actor session protocol. Agent Host Protocol (AHP) from Microsoft was close, but was centered around "chat".The future I envision for agents goes far beyond just text chat. Thus, DASP was born.I'm submitting to HN because I know this is the one place where I'll get real feedback on whether this is an actual need or my tokenmaxxing got the best of me this weekend.This is a builder protocol. I'll be building out clients beyond Elixir and TypeScript, but plan to only support an Elixir server built around my Jido ecosystem.

Could you build this?
No Creating a foundational, distributed distributed-actor communication and recovery protocol requires formal systems design and deep distributed systems consensus expertise.
What it would actually take: The project requires designing a formal wire specification (state machines, idempotency keys, cursor replay semantics, deterministic reconciliation) and reference implementations in Elixir (OTP/GenServer) and TypeScript. The hard part is guaranteeing durable state transitions across network partitions, split-brain scenarios, and multi-client concurrent stream recovery without message loss or out-of-order execution. This demands distributed systems engineers experienced in consensus algorithms, event-sourcing, and actor theory.
