New Bitcoin Proposal BIP-361 Targets Quantum Vulnerability Protection

A new Bitcoin Improvement Proposal (BIP-361) aims to shield vulnerable wallets from quantum threats by halting BTC sent to quantum-attackable addresses and phasing out legacy signatures over five years.

A fresh Bitcoin Improvement Proposal, BIP-361, has been introduced with the goal of protecting wallets that are susceptible to quantum computing attacks.

The proposal outlines three key measures:

  • Prevent new Bitcoin from being sent to addresses deemed vulnerable to quantum attacks.
  • Sunset legacy digital signatures after a five-year transition period.
  • Potentially introduce a recovery mechanism for users who miss the migration window.

The initiative reflects growing concern over the future threat quantum computers pose to cryptographic security in cryptocurrency networks.
