QSAC Coin
Quantum-Secured Algorithmic Currency
This document is for informational purposes, not an offer to sell securities.
1. Executive Summary
QSAC Coin is designed as a practical infrastructure layer for digital payments and settlement, with an emphasis on financial inclusion, transparency, and post-quantum readiness. Version 2.0 retires earlier speculative market projections and reframes the project as an open, compliant, and auditable digital asset network.
The mission of the QSAC Foundation is not to operate as a central bank or monetary authority. Our goal is to provide developers, financial institutions, and public sector partners with a neutral settlement rail that can operate across jurisdictions, integrate with existing compliance frameworks, and maintain operational resilience against emerging quantum threats.
This paper outlines the technical architecture, tokenomics, governance model, and regulatory approach for QSAC. The design prioritizes verifiability over hype, interoperability over isolation, and gradual decentralization under clear accountability.
2. Problem Statement
Fragmented Payments
Cross-border settlement remains slow, expensive, and opaque. Liquidity is siloed across networks, increasing counterparty risk and reconciliation costs.
Lack of Quantum Readiness
Most existing chains rely on ECDSA or EdDSA signatures vulnerable to future quantum attacks. Migration paths are unclear and rarely tested at scale.
Regulatory Uncertainty
Builders and institutions face inconsistent expectations for AML, custody, and reporting. This slows responsible adoption.
3. Solution Overview
The QSAC ecosystem is organized into three core layers, designed for modularity and auditability.
TUCB Core
Transaction Universal Clearing Backend
The transaction processing and validation engine. TUCB Core handles mempool policy, fee markets, and deterministic execution. It is operated by a permissioned validator set at launch, with public slashing and uptime proofs. It is not a central bank.
TUTLE Ledger Engine
Tendermint-style BFT
A proposed DLT based on Tendermint-style BFT consensus. Design targets: 3-second finality and 5,000 TPS under honest-majority assumptions with batched BLS signatures and parallel execution. State is versioned for fast sync.
QSAC ICSS Cloud
Infrastructure and Control Services Stack
JSON-based schema for describing atomic, composable transactions and settlement intents across domains.
State sync, pruning, archival APIs, and merkle proofs for light clients and auditors.
TPM and HSM attestation for validator key generation, rotation, and remote attestation reports.

| Allocation | Percent | Amount | Notes |
|---|---|---|---|

| Treasury | 15% | 1,500,000,000 | Long-term runway |
| Team & Contributors | 15% | 1,500,000,000 | 4-year vest, 1-year cliff |
| Liquidity & Market Making | 15% | 1,500,000,000 | Exchange liquidity |
| Foundation Reserve | 10% | 1,000,000,000 | Operations, legal |
Allocation Breakdown
Chart is illustrative. Final on-chain allocations will be published at genesis.
6. Valuation Approach
Version 2.0 removes prior DCF-based price targets. We adopt scenario modeling based on network usage.
For context only, not as targets: payment-oriented assets such as USDC demonstrate value through settlement volume and integrations. Exchange ecosystem tokens such as BNB illustrate utility-driven demand and burn mechanics. The quantum-resistant blockchain sector is estimated at approximately $6.8B in total market capitalization in 2026.
QSAC valuation will depend on measurable adoption: active addresses, monthly settlement volume, number of institutional integrators, and percentage of supply burned. The Foundation will publish transparent dashboards rather than speculative projections.
7. Governance
The QSAC Foundation will initially steward protocol development, grants, and compliance. All code will be released under Apache 2.0 with public repositories and quarterly transparency reports.
Transition to an on-chain DAO is targeted by year 3. The DAO will control treasury spend, parameter changes including burn rate, and validator set policy via transparent voting. The Foundation commits to a progressive decentralization checklist published in 2026.
8. Regulatory & Compliance
- FATF Travel Rule: support via integrated messaging layer for VASPs.
- AML/KYC: performed by third-party providers at on/off ramp; chain remains pseudonymous.
- Sanctions screening: real-time screening APIs for partners.
- Regulator engagement: target engagement with relevant sandbox programs. We do not claim partnership with IMF or BIS.
9. Security
Key Management
HSM-backed key generation, MPC for signing quorum, planned support for passkey-based wallets.
Post-Quantum Roadmap
Migration to NIST standards: CRYSTALS-Kyber for key encapsulation and CRYSTALS-Dilithium for signatures, targeted by 2027 with hybrid mode in 2026 testnet.
Audits
Quarterly independent audits, public bug bounty, and formal verification for critical modules.
Operational Resilience
Validator diversity requirements, disaster recovery drills, and attested bootstrapping via HAABS.
10. Roadmap
11. Risks and Mitigations
| Category | Risk | Mitigation |
|---|---|---|
| Technical | Consensus failure or exploit | Formal verification, audits, bug bounty, gradual rollout |
| Regulatory | Changing global rules | Compliance by design, sandbox engagement, jurisdictional modularity |
| Market | Low adoption or liquidity | Ecosystem grants, market making allocation, real utility focus |
| Liquidity | Concentration on few venues | Diversified listings, on-chain liquidity incentives |
