In technical circles, the term Q-Day refers to the day when quantum computers reach sufficient power to threaten traditional encryption systems, including algorithms that protect digital currencies such as ECDSA and SHA-256.
🔍 What could happen?
Quantum computers may be able to break digital signatures, which means the ability to steal private keys from public wallets.
It can also threaten entire blockchain networks by decrypting at unprecedented speeds.
⚖️ Current situation:
Despite these concerns, reality proves that the technology is still far from this scenario. Current quantum computers do not exceed a few hundred qubits, while breaking Bitcoin's encryption requires millions of stable qubits, which has not yet been achieved.
🛡️ Proposed solutions:
Working on developing quantum-resistant encryption (Post-Quantum Cryptography).
The readiness of major networks like Bitcoin and Ethereum to transition to new security protocols when needed.
✨ Summary:
The night of collapse is not close, but it remains a future possibility that drives cryptocurrency developers to prepare for the post-quantum era.
