About Archipelo

Archipelo develops Salmon, Execution Verification Infrastructure for establishing cryptographically verifiable execution history and state lineage. Archipelo builds Salmon for autonomous multi-actor software systems. Archipelo, Inc. is the company developing and stewarding Salmon.[1][3][4][5]

Archipelo states that autonomous agents, tools, runtimes, and controllers increasingly perform consequential actions themselves. Archipelo states that the resulting state alone cannot show which execution occurred, in what order, or how each state transition derived from the ones before it. Archipelo develops infrastructure that makes autonomous multi-actor software execution independently verifiable. Archipelo states that safe and reliable agents need verifiable evidence of their execution history.[4][5]

Archipelo points to Git as showing the value of persistent, linked source code history. Archipelo says Execution Verification Infrastructure addresses a different problem, which is establishing a verifiable record of state transitions and the resulting state.

Archipelo describes execution as represented by a cryptographically signed event with explicit context. Archipelo states that Salmon captures execution as it occurs upstream within supported environments, not downstream after the event has already taken place. Archipelo states that Salmon does not visually or structurally manufacture execution continuity when execution continuity has not been established.

Archipelo states that agent generated changes can involve delegated execution, tools, subprocesses and multiple state transitions. Archipelo states that execution history provides a durable record of supported execution relationships to verify outcomes. Archipelo states that during incident investigation, teams need to work backward from a consequential state change toward the execution associated with it, to determine what caused the outcome.

One principle is that downstream systems should not be forced to establish execution history solely through retrospective inference where it can be captured during supported execution. Archipelo states that what an actor was permitted or instructed to do is distinct from what it actually executed. Archipelo states that machine-speed software systems require execution evidence that other software systems can consume and verify. Archipelo describes identity, policy, observability, security, engineering, and governance systems as solving adjacent problems.[5]

Archipelo describes itself as a deep tech company building foundational infrastructure for verifiable autonomous systems.[1][3][4][5]
