Session Chain Proof

Cryptographic proof of session continuity for multi-step AI agents

Problem

When AI agents perform multi-step tasks (editing code, calling external APIs), users and auditors struggle to verify that each step actually ran in order and wasn't tampered with. There's no trusted execution chain record.

Solution

A lightweight library or MCP service that hashes each agent step and links them into a chain, allowing any third party to verify the integrity and order of a session without trusting the agent itself.

Users

AI app developers needing audit trails, engineering teams in compliance-sensitive industries

MVP

SDK for agents to sign after each step; generate verifiable hash chain; CLI or web verifier; export JSON proof

Revenue

Open-source core library; enterprise tier with hosted verification and compliance reports, priced per verification or seat.

Why now

AI agents are entering production, making auditability a must, yet tooling is nearly absent. Cryptographic primitives are mature enough for a solo developer to define a lightweight standard.
