What is Y2Q?

Y2Q (Year2Quantum) is the critical point in time when large-scale quantum computers will be able to break currently ubiquitous asymmetric cryptographic algorithms such as RSA and ECDSA (for example, by executing Shor's algorithm). It is the cybersecurity world's modern equivalent to the Y2K problem, but with much higher stakes for data privacy and financial security.

For traditional, quantum-vulnerable blockchains like Bitcoin and Ethereum, Y2Q represents an existential threat: private keys can be mathematically derived from public addresses, allowing funds—including those in long-dormant wallets—to be stolen. Quantum Coin addresses the Y2Q threat today by implementing the finalized NIST standardized post-quantum cryptography (PQC) algorithms: ML-DSA (FIPS 204), SLH-DSA (FIPS 205), and ML-KEM (FIPS 203) in a robust hybrid mode. This architecture ensures that all network participants are protected against both current classical threats and future quantum adversaries.

To raise awareness of the Y2Q transition, the Y2Q awareness token was launched on the Quantum Coin mainnet. The Y2Q token is the first ERC-20 compatible asset on a production blockchain to be secured by finalized NIST post-quantum standards (ML-DSA, SLH-DSA) in hybrid mode.

The Y2Q token is also meant as a test token for testing the token functionality. The desktop wallet can be used to send and receive tokens.

All accounts on mainnet that had coins or participated in transactions or were genesis validators, as of March 9th 2025 were sent 1000 tokens each. The total supply of #Y2Q is 1,000,000 tokens.
