Protocol 'DEE (Decision Evidence Engine)' to Make Decision-Making 'Provable' Released
VOICE PROTOCOL, operated by Japan Realter Co., Ltd., has open-sourced the verification model for its core technology, DEE (Decision Evidence Engine), which aims to make decision-making processes verifiable. DEE is a protocol that records who, what, how, and the conclusion of a decision in a tamper-proof manner, allowing third parties to verify it. 'Proof' in DEE refers to the reproducibility where the same result can be recalculated from the same input. This technology addresses the challenge of 'accountability' in the AI era and is expected to be utilized in corporate governance, financial/credit assessment, AI decision-making rationale verification, and public policy.

VOICE PROTOCOL, operated by Japan Realter Co., Ltd., has open-sourced the verification model for its core technology, DEE (Decision Evidence Engine). DEE is designed to structure decision-making processes to be verifiable post-facto. The initiative addresses the growing issue of 'black-box' AI decisions and the need for objectively verifiable mechanisms beyond mere explanations. DEE records the entire decision-making process (who, what, how, conclusion) in a tamper-proof, third-party verifiable format. 'Proof' in DEE means 'the same result can be recalculated from the same input (event history, snapshot, verification rules),' ensuring reproducibility. The DEE pipeline includes Event, Ledger, Snapshot, Freeze, Bundle, Verify, and Evidence, guaranteeing deterministic recalculation. Unlike traditional logs or reports, DEE enables active verification. It guarantees the reproducibility and verifiability of the decision process, not the correctness of the outcome itself. A public web portal (/verify) allows third-party verification of snapshotHash and reportHash consistency. The reference implementation is open-sourced on GitHub to ensure transparency. Future applications include corporate governance, financial/credit assessment, AI decision verification, and public policy/consensus building.
