QuantumCoin™
Layer-1 • Proof-of-Work • Post-Quantum

QUANTUMCOIN

A quantum-resistant Proof-of-Work chain with a fixed 22,000,000 cap, ~10-minute blocks, 2-year halvings over ~66 years, and RevStop™ — an owner-local safety circuit you control.

What QuantumCoin™ Is

QuantumCoin™ (QC) is a sound-money, Proof-of-Work Layer-1 that launches already insulated against quantum-era cryptography shocks. QC preserves what made Bitcoin historic— fair distribution, simple rules, no premine—and upgrades the signatures to post-quantum schemes so value today isn’t compromised by the hardware breakthroughs of tomorrow.

The promise is straightforward: a chain you can run, audit, and hold for decades. Predictable issuance (2-year halvings, ~66-year horizon) meets an owner-local safety circuit (RevStop™) that gives holders last-resort control if keys are threatened— without introducing a central authority.

  • Investor clarity: hard cap of 22,000,000 QC; no hidden allocations.
  • Security moat: post-quantum signatures remove “upgrade-under-duress” risk.
  • Durability: PoW issuance, client diversity, and documentation designed for decades.

Founder’s Letter — From Breach to Blueprint

Markets reward the networks that survive. I built QuantumCoin™ after watching quantum research outpace the plans most chains had for “fixing it later.” That gap—between the pace of innovation and the pace of governance—creates a simple risk: when quantum breaks legacy signatures, holders will be asked to trust emergency upgrades under fire.

QC is my answer: prepare now. Keep issuance honest with Proof-of-Work. Keep ownership honest with post-quantum signatures. Give users a personal safety lever with RevStop™ so if keys are targeted, the owner—not a committee—can pull a cryptographic brake on their coins while the network continues moving.

For investors, the thesis is discipline and timing:

I didn’t design QC to be the loudest. I designed it to be the last one standing.

The Quantum Threat (Why This Matters)

QC launches with post-quantum signatures so we don’t need an emergency fork later.

Design Choices

Post-Quantum Signatures

Transactions use PQ schemes designed to resist key-recovery and signature forgery by quantum computers.

Proof-of-Work

Open participation and fair distribution. ~10-minute blocks keep validation predictable.

RevStop™

Owner-local, optional “circuit breaker.” If keys are compromised, the owner can pause spends of their UTXOs.

Broad Nodes

Archival for explorers, pruned for low storage, and light/SPV for phones—to maximize decentralization.

Monetary Policy

DistributionProof-of-Work mining

Simple, transparent economics — issuance decays predictably to the hard cap.

RevStop™ (Owner-Local Protection)

Mining

Mining secures the chain and distributes new QC. Difficulty targets ~10-minute blocks. Hardware choice is open—run what you have, optimize if you want. The policy discourages surprises: predictable halvings, no stealth inflation, and validation code that favors readability.

Running a Node

Archival

Full history for explorers and research — highest storage, best for analytics & infra providers.

Pruned

Validates the tip with low storage by discarding old blocks while keeping full security.

Light/SPV

Header-based proofs for mobile devices — verify payments without full blocks.

Governance & Upgrades

QC favors conservative governance. Consensus rules change only with broad community support and exhaustive review. Client diversity and reproducible builds are prioritized to minimize correlated risk.

Roadmap

  1. Live Mainnet — PQ signatures, PoW issuance, explorer & public APIs.
  2. Wallet Ecosystem — Light/SPV clients, hardware wallet support, safety UX for RevStop™.
  3. Tooling & Docs — SDKs, reproducible builds, node ops guides, integrations.

FAQ

Is QuantumCoin™ a fork?

No. QC is an independent PoW chain designed around post-quantum signatures and a simple monetary policy.

How do RevStop™ and decentralization coexist?

RevStop™ is local and cryptographically authorized by the wallet owner; it cannot pause others’ funds or the chain.

How do I participate?

Run a pruned node, mine, contribute to code/docs, or build apps on top of the explorer & API.
