New Bitcoin Proposal Targets Quantum Threats with Plan to Phase Out Legacy Signatures

A newly proposed Bitcoin Improvement Proposal (BIP) outlines a strategy to safeguard the network against potential future threats from quantum computing.

The BIP, titled ‘Post Quantum Migration and Legacy Signature Sunset’, advocates for a structured migration away from Bitcoin’s current cryptographic signatures. It warns that advancements in quantum computing pose a significant risk to the network’s security, particularly as nearly 30% of Bitcoin’s unspent transaction outputs currently have exposed public keys, making them potentially vulnerable earlier.

To counter this threat, the proposal lays out a two-phase approach. Initially, measures would be implemented to prevent the emergence of new vulnerabilities exploitable by quantum computers.

Approximately five years following the adoption of the initial phase, a second stage would commence the sunsetting of Bitcoin’s legacy signature schemes. This phase-out is deemed essential to comprehensively protect the network against sophisticated quantum adversaries.

Implementing this proposal requires significant coordination across the Bitcoin ecosystem. Developers, miners, exchanges, and end-user wallet providers would all need to participate in the upgrade process.

The proposal underscores the high stakes involved, stating that a successful large-scale quantum attack could severely compromise Bitcoin’s network security and destabilize its economic foundations.
