Quantum-Safe Cryptocurrency: $QRL
QRL launched in 2018 with XMSS hash-based signatures - built for long-term cryptographic resilience.
Quantum News
On March 30, 2026, Google Quantum AI (with the Ethereum Foundation and Stanford) showed that breaking Bitcoin's encryption needs 20x fewer qubits than previously estimated, under 500,000 physical qubits, and could derive a private key in ~9 minutes, inside Bitcoin's 10-minute confirmation window. The gap has only widened since: QuEra set a verified record of 96 logical qubits, the US Department of Energy is pushing for a fault-tolerant machine by 2028, and ~6.9 million BTC (including ~1.7 million Satoshi-era coins) still sit in permanently exposed addresses. Google has set its own 2029 migration deadline.
The QRL Story
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 QRL 2.0 brings full EVM smart-contract support without giving up post-quantum security. Bitcoin has only a partial testnet proposal; Ethereum's roadmap reaches just its base layer by 2029 at the earliest, leaving every account and contract on top still to migrate. Neither is a complete solution. QRL users have been protected since day one.

"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, and only against one of two attack types - the ~$470 billion already in exposed addresses stays exposed, forever. "Won't Ethereum's roadmap fix it?" Its 2029 target covers the base layer only - hundreds of millions of accounts, every smart contract, bridges, and L2s still have to migrate on top of it. "Why target crypto specifically?" Because blockchain keys are public and permanent. The Federal Reserve already warned you.

A fully post-quantum EVM chain - quantum-safe from genesis, not bolted on later. Port your Ethereum contracts with minimal code changes, often just a few lines. Post-quantum signatures are built in from genesis, so there is no migration, no emergency hard fork, no scramble. Testnet V2 is live (launched March 31, 2026) and its post-quantum cryptography passed an independent Halborn audit with no vulnerabilities found. Early builders get first-mover advantage on the chain that never needs to upgrade its cryptography.
