Nova proposta do Bitcoin quer congelar carteiras vulneráveis à computação quântica
By Fernando Martines
Bitcoin developers and researchers have introduced BIP-361, a proposal to gradually restrict the use of addresses vulnerable to quantum computing attacks, particularly older P2PK types with exposed public keys. The phased plan prohibits new funds to these addresses, invalidates transactions using current signatures like ECDSA and Schnorr after a set date, and includes future fund recovery via seed phrases. This addresses risks from emerging quantum computers around 2027-2030, with over 34% of bitcoins potentially exposed.
