DigiByte Quantum Shield – v3 Architecture Proposal

[DarekDGB]

Hello DigiByte Developers 👋

My name is Darek (@DarekDGB).
Over the past months, I’ve been building a contract-locked, fail-closed, quantum-era security architecture for DigiByte — inspired by biological immune systems, but engineered with strict determinism and minimal authority.

All components are open-source, MIT-licensed, and designed so DigiByte Core (or ecosystem projects) can evaluate, reuse, or integrate individual parts without committing to the full system.

The architecture has now evolved to Shield Contract v3, with a clear separation between detection, aggregation, orchestration, wallet enforcement, and intelligence reporting.

🔷 Architecture Overview (Shield Contract v3)

The system is composed of independent v3 modules, coordinated by a deterministic orchestrator.
Each module has no hidden authority and communicates only through explicit contracts.

1️⃣ Sentinel AI v3 — Detection Layer

Deterministic emission of anomaly and risk signals from network, node, or wallet context.

2️⃣ DQSN v3 — DigiByte Quantum Shield Network

Read-only aggregation and normalization of signals across sources, producing stable network-level risk indicators.

3️⃣ ADN v3 — Active Defense Network

Local defensive signaling (e.g. lockdown state, degradation mode), without executing policy itself.

4️⃣ Guardian Wallet v3

Wallet-level enforcement hooks (cooldowns, throttles, guard states), policy-agnostic and fail-closed.

5️⃣ Quantum Wallet Guard (QWG) v3

Cryptographic and signature-risk guardrails, designed with post-quantum migration in mind.

6️⃣ Adaptive Core v3 — Intelligence & Reporting Layer

A read-only intelligence core that receives deterministic reports from all layers and produces human-reviewed upgrade recommendations.
It has no authority to change system behavior.

🔹 Shield Orchestrator v3 (Coordination Layer)

A deterministic orchestration layer that:
• invokes all Shield v3 components in fixed order
• synthesizes a single fail-closed v3 envelope
• forwards reports to Adaptive Core as a read-only sink

🔵 Design Principles (v3)
• Deny-by-default — ambiguity always results in denial
• Deterministic execution — same input → same output → same hash
• Strict contracts — versioned envelopes, reason IDs, and traces
• No hidden authority — no auto-execution, no escalation by magic
• Modular & optional — each component can stand alone
• Consensus-neutral — no changes to DigiByte consensus rules

⸻

🔵 Purpose

The goal of this work is not to replace DigiByte Core, but to offer:
• a modular security framework for the quantum and AI era
• reference implementations for wallet and network defense
• a contract-first approach to layered security
• ideas and code that DigiByte developers can reuse, critique, or ignore freely

Nothing here requires protocol changes, governance authority, or trust assumptions.

🔵 What I’m asking from the DigiByte team

If any of this is useful, I would deeply appreciate:
• architectural feedback
• critique of assumptions or threat models
• discussion about long-term security direction (especially post-quantum)
• guidance on where (if anywhere) parts of this could benefit DigiByte

My DMs on X are open to all DigiByte developers.

Thank you for keeping DigiByte alive, decentralized, and resilient for over a decade.
Much respect to all of you. 🙏
