Bitcoin could be headed for its most sweeping cryptographic overhaul yet if a new proposal gains traction.
A draft Bitcoin Improvement Proposal (BIP) titled Quantum-Resistant Address Migration Protocol (QRAMP) has been introduced by developer Agustin Cruz. It outlines a plan to enforce a network-wide migration of BTC from legacy wallets to ones secured by post-quantum cryptography.
Quantum computing involves moving away from a process reliant on binary code, ones and zeros, and exponentially increasing computing power by employing Quantum bits (qubits) that exist in multiple states simultaneously. Such a jump in power is expected to threaten modern computing encryption built by classic machines.
The proposal suggests that after a predetermined block height, nodes running the updated software would reject any transaction trying to spend coins from an address using ECDSA cryptography, which could theoretically make it vulnerable to quantum attacks.
