QSCOIN Whitepaper

Quantum-Safe • Hybrid PQC • zk Privacy • PoS + VRF • 81,000,000 max supply

Abstract

QSCOIN is a quantum-safe cryptocurrency focused on long-term security and mainstream usability. We combine post-quantum cryptography (PQC) with classical primitives in a hybrid signature scheme, zk-rollups for scalability & privacy, and a PoS + VRF consensus design. The supply is capped at 81,000,000 QSC. The protocol emphasizes account abstraction, developer-friendly tooling, and open governance.

1. Vision & Principles

  • Quantum-safe by default: protect users today and tomorrow.
  • Pragmatic privacy: zk for payments & proofs without harming compliance.
  • Human UX: AA wallets, social recovery, and session keys.
  • Open & modular: auditable, extensible, and client-friendly.

2. Cryptography & Security

2.1 Hybrid Signatures (PQ + classical)

Default accounts bind a classical signature (e.g., Ed25519) with a PQC signature (e.g., CRYSTALS-Dilithium) in a single verification path. This enables graceful migration and hardware compatibility while ensuring quantum resilience.

2.2 Randomness (VRF)

A Verifiable Random Function selects proposers/committers and drives lottery-like leader election, mitigating grinding and bias.

2.3 Audit & Bug-bounty

Open audits, reference testnets, and a standing bug-bounty program with public disclosures and regression suites.

3. Consensus & Protocol

3.1 PoS + VRF

Stake-weighted, VRF-assisted proposer/committee selection with fast finality and slashing for equivocation or safety violations.

3.2 zk-Rollups (L2)

zk-rollups batch transactions, generating succinct validity proofs posted on L1, enabling high throughput and low fees with strong security.

3.3 Fees & MEV controls

Dynamic basefee + inclusion lists, soft PBS, and encrypted mempool experiments to reduce harmful MEV.

4. Tokenomics

  • Max supply: 81,000,000 QSC
  • Use: staking, fees, governance, security incentives

Initial Allocation (Draft)

  • Community & ecosystem: 36%
  • Staking & security: 24%
  • R&D & grants: 20%
  • Treasury (locked/vested): 20%

Figures are work-in-progress and subject to community review.

5. Privacy (zk)

Optional zk payment proofs and selective disclosure (view keys, proof-of-payment) to support business workflows and compliance-friendly privacy.

6. Account Abstraction & UX

  • Passkeys/social recovery; multi-device MPC
  • Session keys & batched actions; gas-sponsored flows
  • Human-readable handles and safety checks for destinations

7. Governance

Open governance with on-chain signaling, security budget oversight, and upgrade frameworks for PQC agility.

8. Roadmap

  1. Phase 1 — Litepaper, website, devnet
  2. Phase 2 — Testnet, audits, wallet AA
  3. Phase 3 — Mainnet genesis, zk-rollup beta
  4. Phase 4 — Ecosystem growth & L2 roadmap

9. Risks & Disclaimers

  • Cryptography shifts and PQ assumptions may evolve.
  • Economic parameters can change via governance.
  • No investment advice; high risk technology.

10. Comparative Landscape

Bitcoin (BTC)

SHA-256/ECDSA (no-PQC), PoW robust but high cost/latency. QSCOIN prioritizes today quantum defense and UX (AA, zk), with strong security via PoS + VRF and rollups.

Ethereum (ETH)

PoS + rollups, massive ecosystem. QSCOIN is born quantum-ready (hybrid PQC), pushing AA and zk payments by default.

Solana (SOL)

Very high throughput (PoH/PoS), monolithic focus; no native PQC. QSCOIN opts for modularity with rollups and hybrid signatures.

Tezos (XTZ)

On-chain governance and elegant upgrades; no base PQC today. QSCOIN integrates PQC/AA/zk from first design.

QRL

PQC pioneer (XMSS) with performance/UX trade-offs. QSCOIN aims for pragmatic balance: hybrid PQ + classical, AA, zk-rollups and broad hardware compatibility.
