================================================================================ SOQUCOIN USE CASES EXECUTIVE SUMMARY For Partners & Investors ================================================================================ Document Version: 1.0 Date: January 2026 Contact: foundation@soqu.org Website: https://foundation.soqu.org ================================================================================ EXECUTIVE OVERVIEW ================================================================================ Soqucoin is the first production-grade, post-quantum secure Layer 1 blockchain, built specifically for high-value settlement applications. Using NIST-standardized Dilithium (ML-DSA-44) signatures, every transaction is resistant to quantum attacks from day one. This document outlines two strategic use cases currently in development: 1. SOQ Lightning - Post-Quantum L2 Payment Network 2. Quantum-Secure Stablecoins - Institutional Digital Dollars ================================================================================ USE CASE 1: SOQ LIGHTNING Post-Quantum L2 Payments ================================================================================ OVERVIEW -------- A Layer 2 payment channel network built on Soqucoin's quantum-resistant foundation. Unlike Bitcoin Lightning, SOQ Lightning uses post-quantum adaptor signatures ensuring long-term security as quantum computing advances. MARKET OPPORTUNITY ------------------ • $150T+ Global payments market (2025) • $600B+ Annual remittance flows • $500B+ Cross-border B2B payments • $340B Gaming industry (micropayments) • 6.5% Average remittance fee (our target: <1%) • 3-5 days Traditional settlement time (our target: <1 second) Sources: World Bank Remittance Prices, BIS, Statista, McKinsey Global Payments 2025 KEY METRICS ----------- • Payment Finality: <1 second • Transaction Fee: ~0.001 SOQ • Throughput: 1,000s TPS • Security: Post-quantum adaptor signatures TECHNICAL DIFFERENTIATORS ------------------------- • Post-Quantum HTLCs - Hash Time-Locked Contracts secured by Dilithium • Instant Payments - Sub-second finality for retail and micropayments • Cross-Chain Swaps - Atomic swaps via quantum-resistant bridge contracts • Merchant Ready - POS compatible with instant L1 settlement TARGET APPLICATIONS ------------------- • Retail payments (coffee shops, restaurants, e-commerce) • Gaming & micropayments (in-game purchases, streaming tips) • Cross-border remittances (seconds instead of days) TIMELINE: Stage 5 - 2027 ================================================================================ USE CASE 2: QUANTUM-SECURE STABLECOINS Institutional Digital Dollars ================================================================================ OVERVIEW -------- The $280+ billion stablecoin market runs entirely on quantum-vulnerable cryptography (ECDSA). Soqucoin offers the first production-grade settlement layer for institutional-grade stablecoins with full post-quantum privacy through our Lattice-BP++ hybrid approach. MARKET OPPORTUNITY ------------------ • $280B+ Current stablecoin market cap • 100% Major stables on quantum-vulnerable chains • $0 PQ-secure stablecoins in production today • 2030-2035 NIST/White House PQC migration deadline • $50B+ Enterprise treasury stablecoin holdings • 130+ Countries exploring CBDCs Sources: CoinGecko, NIST PQC Standards, White House NSM-10, Atlantic Council KEY DIFFERENTIATORS ------------------- • Dilithium ML-DSA-44 - NIST FIPS 204 compliant signatures • Lattice-BP++ Privacy - Hybrid lattice + Bulletproofs++ (fully PQ-secure) • Solana Bridge - Wrapped stablecoins (psUSD) for DeFi liquidity • Proof of Reserves - Cryptographic attestations for transparent backing TARGET APPLICATIONS ------------------- • Institutional treasury (corporate holdings, family offices) • DeFi collateral (lending protocols on PQ infrastructure) • CBDC infrastructure (central bank digital currency pilots) • Cross-border settlement (fast, secure international transfers) TIMELINE: Q3 2026 ================================================================================ TECHNICAL FOUNDATION ================================================================================ CRYPTOGRAPHIC STACK ------------------- Layer Technology Standard ───────────────────────────────────────────────────────────── Signatures Dilithium ML-DSA-44 NIST FIPS 204 Address Hashing BLAKE2b-160 RFC 7693 Address Encoding Bech32m ("sq1") BIP-350 Privacy Lattice-BP++ Hybrid Post-quantum range proofs Batch Verification PAT Merkle commitment Soqucoin-native Key Derivation HKDF-SHA256 RFC 5869 CONSENSUS & NETWORK ------------------- • Mining Algorithm: Scrypt (ASIC-compatible) • Merged Mining: AuxPoW with Litecoin/Dogecoin • Chain ID: 0x5351 (unique) • Block Time: 2.5 minutes • Dilithium Verify: 0.175ms ================================================================================ PROJECT MILESTONES ================================================================================ Q1 2026 Mainnet Launch (Halborn security audit in progress) Q2 2026 Bulletproofs++ privacy activation Q3 2026 Stablecoin MVP (sSOQ-USD token specification) Q4 2026 Solana Bridge (pSOQ Wormhole integration) 2027 SOQ Lightning (L2 payment channels) ================================================================================ PARTNERSHIP OPPORTUNITIES ================================================================================ We are seeking strategic partners across the following categories: STABLECOIN ISSUERS • First-mover advantage on quantum-secure infrastructure • Technical integration support QUALIFIED CUSTODIANS • Custody solutions for PQ assets • Proof-of-reserves integration INSTITUTIONAL INVESTORS • Seed and strategic investment opportunities • Foundation advisory roles EXCHANGES • Early listing partnerships • Integration documentation support ================================================================================ CONTACT & LINKS ================================================================================ Foundation Email: foundation@soqu.org Project Website: https://soqu.org Foundation Website: https://foundation.soqu.org GitHub: https://github.com/soqucoin Whitepaper: https://soqu.org/whitepaper.html Soqucoin Foundation EIN: 41-3556422 30 N Gould St #47158 Sheridan, WY 82801, USA ================================================================================ © 2026 Soqucoin Foundation.
