immo.quick Serverless Edition: Institutional Trust Infrastructure — Comprehensive Technical & Strategic White Paper

immo. quick Serverless Edition — Institutional Trust Infrastructure for Regulatory-Compliant Real Estate and Financial Transactions Description (Abstract) immo. quick Serverless Edition is an open-architecture Institutional Trust Infrastructure platform that automates regulatory compliance for real estate and financial transactions through a deterministic 7-gate execution pipeline — called Machine Law. Legal rules are encoded as pure, auditable code functions, eliminating interpretive ambiguity and providing cryptographically verifiable compliance receipts. Core Architecture The platform implements a sequential 7-gate compliance pipeline: Gate 1 — Sovereign Identity / DID: KYC, AML, OFAC screening with Decentralized Identifier verification Gate 2 — Software Attestation: Runtime code integrity verification via SHA-256 hash pinning (Cloudflare Workers) Gate 3 — Legal Rule Enforcement: Machine-executable rules across 16 frameworks (GDPR, DORA, NIS2, BaFin, FINMA, FinCEN, OFAC, eIDAS, EU AI Act, PSD3/PSR, MiCA, AMLD6, FATCA/CRS, CTA/BOI, Swiss Civil Code, UK ECCTA) Gate 4 — Risk Scoring: Composite AML/PEP/jurisdiction/transaction-type risk engine Gate 5 — Dual Approval (Six-Eyes): Three-instance cryptographic sign-off (Legal × CCO × CISO) with multi-sig hash Gate 6 — Witness Record: Tamper-proof D1 audit log with optional Polygon PoS blockchain anchoring Gate 7 — Warranty Token: Hybrid Ed25519 + ML-DSA-65 (NIST FIPS 204) cryptographic compliance receipt Key Technical Features Hybrid Post-Quantum Cryptography: Phase 2 migration — Ed25519 + ML-DSA-65 (CRYSTALS-Dilithium, NIST Level 3 ≈ AES-192), compliant with BSI TR-02102-1 and NIST FIPS 204 Software Attestation: Runtime WORKERVERSIONHASH comparison against pinned deployment hash — detects code tampering before any compliance gate executes Shamir Secret Sharing (2-of-3): Key ceremony orchestration with distributed key holder management; no single point of key compromise Automated Regression Testing: 55 deterministic test vectors across 15 regulatory frameworks, CI/CD deploy-gate enforcement Blockchain Anchoring: Merkle root anchoring of WitnessRecords to Polygon PoS for immutable third-party verifiability SIEM Export: Splunk/QRadar/Azure Sentinel-compatible audit log dispatch Multi-Tenant Isolation: Per-org API key, quota management, data residency (EU), BYOK support Regulatory Change Management: AI-assisted regulatory scanning, three-instance approval pipeline for rule updates, version-locked deployment Compliance Coverage Framework Scope DORA Art. 17–23 ICT incident classification, 4h/24h/72h reporting SLA NIS2 Art. 21–23 Significant incident reporting, supply chain security GDPR Art. 25/32/33 Data minimisation, pseudonymisation, breach notification BaFin MaRisk/BAIT German banking supervisory requirements FINMA Circ. 2023/1 Swiss financial market supervisory requirements FinCEN/BSA + OFAC US AML/CTF and sanctions screening eIDAS 2. 0 / QES Qualified electronic signature verification EU AI Act High-risk AI system governance Technology Stack Edge Runtime: Cloudflare Workers (zero cold-start, 200+ PoP global distribution) Audit Storage: Cloudflare D1 (SQLite-compatible, append-only audit log) Rule Storage: Cloudflare KV (globally replicated rule registry) Secret Management: Infisical (HSM-compatible, audit-logged key access) Frontend: React 18 + Vite + Tailwind CSS (JetBrains Mono terminal aesthetic) Cryptography: Web Crypto API (SHA-256, HMAC), ML-DSA-65 simulation layer (roadmap: @noble/post-quantum) Blockchain: Polygon PoS (Merkle root anchoring, ~2s finality, ~€0. 001/tx)
