Architecture

Backpac is the High-Fidelity Signal Path for deterministic settlement.

It operates as a protocol control surface that transforms fragmented network noise into a unified, verifiable orchestration loop.

The Settlement Loop

The system is designed around a continuous feedback circuit that ensures intents land with absolute certainty.

Core Circuitry

1. Institutional Entry (Entry Point)

The secure entrance for all institutional traffic. It enforces access control and initializes the state-aware session for the incoming intent.

2. Orchestration Engine

The logic core. It evaluates the optimal path for settlement based on real-time telemetry, historical slot-drift, and provider latency. It chooses between Probabilistic (best-effort) and Deterministic (guaranteed) paths.

3. The Telemetry Tap (Observability)

Unlike legacy "logging," the Telemetry Tap is a primary circuit. It extracts sub-second data from every network slot, reorg, and provider failure, feeding it back into the orchestration engine to prevent future failure.

4. Forensic Audit & Verification

The terminal state of the loop. Every intent is tracked to its cryptographic finality. This provides the Verifiable Visibility required for global money movement.

Backpac architecture is defined by the logic of certainty, not the commodity of the cloud.
