Crypto Industry Accelerates Response to Quantum Threat

The crypto industry is racing to address the potential threat of quantum computers, which could compromise the security of blockchain infrastructure.

Blockstream has taken a significant step in this direction by deploying post-quantum signature verification on its Liquid Network. This move enables opt-in post-quantum signing and does not require consensus changes to Liquid.

Meanwhile, Google Quantum AI has published updated estimates for the resources required to break Bitcoin's elliptic-curve cryptography using a quantum computer. According to these estimates, fewer than 500,000 physical qubits may be needed to execute an attack path.
