Trans-Causal Monetary Protocol (TCMP)

Purpose

TCMP governs financial interactions that:

• Influence past and future states simultaneously
• Must remain causally consistent
• Operate across timelines where cause/effect ordering is not guaranteed

This enables causality-stable monetary operations across:

• Temporal loops
• Retrocausal data flows
• Forward-predicted CBDC states
• Quantum timelines

Transaction Structure

A Trans-Causal Transaction (TCX) has the structure:

TCX = {
  present_state: S0,
  future_projection: S+,
  past_alignment: S-,
  causal_hash: HASH(S0 + S+ + S-),
  integrity_weight: ψ
}

Causal-Coherence Constraint

A TCX is legal only when:

causal_coherence = f(S0, S+, S-) ≥ threshold

If coherence fails:

• Transaction is deferred
• DBIS applies causal-resolution mapping

API Endpoints

• POST /api/v1/tcmp/transactions - Create trans-causal transaction
• GET /api/v1/tcmp/transactions/:tcxId - Get transaction
• POST /api/v1/tcmp/transactions/:tcxId/resolve - Resolve deferred transaction

Resolution Types

When coherence fails, TCMP applies resolution based on:

• temporal_loop - Defer until loop resolved
• retrocausal - Apply retrocausal correction
• forward_predicted - Validate prediction confidence
• quantum_timeline - Collapse quantum states
