CrowdfundingVault: 门限 MPC 智能信托托管、美国 SEC Reg CF 合规及抗量子资金原子清结算

CrowdfundingVault Multi-Party Escrow Architecture & Timelock Topology

Threshold lattice signatures, automated milestone escrow release, and regulatory audit trail

Central System: Escrow Vault Core - Threshold MPC Controller

Cryptographic Nodes

• Threshold Lattice Signer
• Milestone Escrow Gate
• Quantum Timelock Engine
• SEC Reg CF Auditor
• Instant Refund Disburser

Architectural Layers & Protocols

• Distributed Threshold Cryptography (Threshold ML-DSA (t-of-n) Distributed Key Generation): Eliminating single points of custody: private keys are split into mathematical shares across independent guardians.
• Verifiable Timelock Escrow (Sequential Squaring VDF / Sloth Delay Functions): Locking investor capital until campaign deadlines expire or verified governance milestones are achieved.
• Quantum-Secure Smart Contracts (EVM PQC Precompiles / Rust CosmWasm Enclaves): Executing trustless escrow logic and cap-table management on quantum-resilient ledgers.
• Regulatory & FinTech Compliance (SEC Reg CF / Reg A+ / MiCA Audit Pipelines): Generating cryptographically verifiable evidence of KYC/AML, investor limits, and fund segregation.

Key Metrics: t-of-n MPC (Custody Redundancy) | $0 Custody Risk (Single-Key Exposure Eliminated) | 100% (Automated Milestone Escrow) | SEC Reg CF (Compliance Verification)
