Quantum-hardened digital gold. For everyone. Forever.

Qubit TopCoin is an open source, quantum-resistant cryptocurrency built from the ground up for the post-quantum era. Where Bitcoin and Ethereum rely on elliptic curve cryptography that quantum computers will eventually break, QTOP is secured by FALCON-512 — a post-quantum signature scheme standardized by the US National Institute of Standards and Technology (NIST) in 2024.

Every major cryptocurrency today is vulnerable to a sufficiently powerful quantum computer. The threat is not theoretical — it is an engineering timeline. An adversary can harvest encrypted transactions today and decrypt them retroactively once quantum capability arrives — a strategy known as "harvest now, decrypt later."

QTOP is built to make that impossible, using cryptography designed to remain secure for generations.

Quantum-resistant from block zero Every other major cryptocurrency is retrofitting quantum resistance onto a vulnerable system. QTOP is built with post-quantum cryptography as its foundation — not an afterthought.

CPU-native mining with RandomX QTOP uses RandomX — the same algorithm that powers Monero — specifically designed to run best on ordinary CPUs. No ASICs. No GPU farms. A laptop mines QTOP on equal terms with a datacenter. This is how decentralization stays real.

FALCON-512 node identity Every QTOP node has a persistent FALCON-512 keypair as its network identity. All node communications are authenticated with post-quantum signatures — not just transactions.

No premine. No advantage. Every QTOP in existence is earned through proof-of-work mining beginning at the genesis block. No developer allocation. No foundation reserve. No ICO. The first miner and the last miner play by identical rules.

Long-term wealth storage QTOP is designed not just for today's threat landscape but for the next 50 years. FALCON-512 is secure against all currently known quantum algorithms. A fixed supply of 21,000,000 QTOP combined with quantum-resistant security makes QTOP a credible generational store of value.

cd qtopcore

# Basic node (rewards go to internal wallet)
cargo run --bin qtopcore -- 5003

# Node with your wallet address (recommended)
cargo run --bin qtopcore -- 5003 YOUR_QTOP_ADDRESS

# Check node status
curl http://localhost:5003/status

# Check your balance
curl http://localhost:5003/balance/YOUR_QTOP_ADDRESS

cd qtopcore

# Start the CPU miner
cargo run --bin miner -- YOUR_QTOP_ADDRESS

# Mine to a different node
cargo run --bin miner -- YOUR_QTOP_ADDRESS http://node-address:5003

The miner automatically:

• Connects to your node
• Registers your wallet address for rewards
• Polls for pending transactions every 5 seconds
• Mines blocks using RandomX proof of work
• Tracks earnings and displays wallet balance

cd qtopcore

# Create new encrypted wallet
cargo run --bin qtopwallet -- create

# Check balance
cargo run --bin qtopwallet -- balance

# Send QTOP
cargo run --bin qtopwallet -- send

# Show address
cargo run --bin qtopwallet -- address

Wallets are encrypted with AES-256-GCM and PBKDF2 key derivation. Your private key is never stored in plain text.
