Cross-Model Consensus Engine
Algorithm implementation based on the COE (Cognition-Oriented Emergence) Protocol (Wang, 2026).
Core Problem
When multiple agents (humans, AI models, robots) observe the same physical space, how do they reach a verifiable consensus on "what the world is"?
Consensus Policies
| Policy | Use Case | Rule |
|---|---|---|
| Simple Majority | Small equal-trust groups | Confirmations exceed 50% of all verifications received |
| Weighted Trust | Heterogeneous agents with different reliability | Sum of (trust_weight * confidence) exceeds threshold |
| BFT | High-security with potential malicious agents | More than f+1 confirmations out of at least 2f+1 total verifications |
Shared World State (SWS)
Whenever consensus is reached, the engine produces an SWS record containing:
subject/predicate/value— the agreed-upon factconfidence— aggregated confidence scorebased_on— event IDs of the underlying J/V eventsconsensus_policy— policy used to reach agreementconfirmations— number of confirming verifications

Relationship with JEP
- COE answers "what the world is" — cognitive consensus, ex-ante / in-situ collaboration.
- JEP answers "who is responsible" — accountability tracing, post-hoc audit.
- COE events may be referenced by JEP as evidence. Together they form a complete cognition-accountability dual-loop.
