Thoughtchain: A Cryptographic Protocol for Verifiable Cognition and Memory Integrity in Intelligent Systems
Thoughtchain is the first complete protocol for securing cognition itself. Authored by Matthew Wise, Sole Creator, Protocol Architect & Steward, the whitepaper extends the trust model of public-key cryptography and blockchain into the epistemic domain—making what an agent knew, remembered, and reasoned cryptographically verifiable. It defines the cryptographic substrate for verifiable cognition—anchoring memory, reasoning, and cognitive transitions in a public, version-controlled DAG—and formalizes six primitives: Proof of Prompt (PoP), Proof of Memory (PoM), Proof of Cognition (PoCog), Epistemic Diff, CommitID, and the Cognitive Virtual Machine (CVM). Thoughtchain establishes the epistemic trust layer beneath intelligent systems—where cognition itself becomes auditable.
