Quantum-Safe Cryptocurrency: $QRL
QRL launched in 2018 with XMSS hash-based signatures — built for long-term cryptographic resilience.
Google Just Set a Deadline. Bitcoin Hasn't Set One.
On March 25, 2026, Google officially warned that quantum computers could break today's encryption by 2029 - and immediately started migrating its own systems. This is the company that builds quantum chips telling the world the clock is real. Meanwhile, ~6.9 million BTC sit in addresses where the public key is already permanently exposed on-chain, a quantum attack on Bitcoin's ECDSA now requires as few as 1,098 logical qubits (EUROCRYPT 2026), and Bitcoin has no complete defence: BIP-360 is on testnet with no mainnet date, protects only new addresses against only one of two attack types, and does nothing for the ~$470 billion already sitting in exposed addresses. Even if BIP-360 activated tomorrow, the majority of Bitcoin's quantum vulnerability would remain. Migration takes 5-7 years. Google started. Bitcoin hasn't.

The QRL Approach
8 Years Ahead. Still the Only One.
In 2016, a cancer surgeon saw what the crypto world refused to see. In 2018, QRL launched the world's first quantum-resistant blockchain. In 2026, it remains the most established quantum-safe chain in production - and is soon to become the first EVM-compatible quantum-resistant chain, bringing full smart contract support without sacrificing post-quantum security. Bitcoin has a partial testnet proposal. Ethereum has a seven-fork plan that won't complete until 2029 at the earliest - and neither is a complete solution. QRL users have been protected since day one.
Read the Origin Story →The Questions Crypto Won't Answer
"Isn't quantum 20+ years away?" Google just set a 2029 deadline and started migrating. "Won't BIP-360 fix Bitcoin?" It protects only new addresses against one of two attack types - the ~$470 billion already in exposed addresses stays exposed, forever. "Won't Ethereum's roadmap fix it?" Seven forks through 2029 is a plan, not a solution - and that's the optimistic timeline. "Why target crypto specifically?" Because blockchain keys are public and permanent. The Federal Reserve already warned you.

The only quantum-resistant EVM chain. Port your Ethereum contracts with minimal code changes - often just a few lines. Post-quantum signatures built in from genesis. No migration, no emergency hard fork, no scramble. Testnet V2 launching Q1 2026. Early builders get first-mover advantage on the chain that never needs to upgrade its cryptography.
