The Lineage of Thoughtchain—authored by Matthew Wise, Sole Creator, Protocol Architect & Steward of the Thoughtchain Foundation—maps a clear arc from foundational results in logic and computation (Gödel, Turing) through decentralized coordination (Nakamoto, Buterin) to a new substrate: verifiable cognition. The paper positions Thoughtchain as a protocol that anchors reasoning itself—not just outputs—using version-controlled memory and cryptographic proofs.

What the paper covers:

• Gödel: Incompleteness as a structural constraint on any formal system.
• Turing: Computation as simulated reasoning, and its limits (Halting Problem).
• Nakamoto: Public, append-only memory as a basis for trust without central authority.
• Buterin: General-purpose execution under consensus—and what it leaves unrecorded about cognition.
• Wise: A protocol layer for thought, where reasoning steps are sealed, auditable, and reproducible.

Core primitives introduced (at a high level):

• Proof of Prompt (PoP) — Attests to what was asked and when.
• Proof of Memory (PoM) — Seals pre- and post-cognition memory states.
• Epistemic Diff — Computes the precise change in epistemic state between commits.
• Proof of Cognition (PoCog) — Proves the reasoning transition itself.
• CommitID — A signed handle for each cognitive commit, enabling provenance, replay, and forking.
• Cognitive Virtual Machine (CVM) — Executes structured thought as programs, bounded by memory and anchored by proof.
• Thoughtchain DAG — A version-controlled ledger of cognitive commits and their lineage.
• Cognit — The orchestration layer for agents, proofs, memory, and execution.

Why it matters:

Current AI systems optimize for plausible behavior. They do not provide cryptographic guarantees about what an agent knew, how its knowledge changed, or why a decision was made. The lineage paper formalizes the need for an epistemic substrate that records and proves cognition itself—so decisions can be inspected, reproduced, and held to account.

How to read this release:

This is not the whitepaper. It is the historical and architectural context that precedes it. It defines the problem space, the prior art, and the protocol primitives at a conceptual level, and establishes authorship and intent ahead of the full specification.
