Post-quantum Cryptography

A paper published by BTQ Technologies calculates that using quantum computers to mine bitcoin at current difficulty would demand roughly 10 to the power of 25 watts — approaching stellar energy output — and argues the real quantum threat lies in cryptographic signatures, not mining.

The USDC issuer's Layer-1 blockchain will ship post-quantum signature support at mainnet, making it one of the first production chains to offer opt-in protection against the threat that keeps cryptographers awake at night.
