Facing this anticipated deadline, several cryptocurrencies are actively developing quantum resistance solutions. Algorand, QAN and IOTA already integrate signatures based on cryptographic schemes considered secure against quantum attacks. These protocols use algorithms such as Lamport or lattice-based signatures<\/strong>.<\/p>\n\n\n\nFor Bitcoin holders, the most effective defensive strategy<\/strong> currently involves never reusing addresses. A public key is only exposed when spending funds, thus limiting the potential attack window. Unspent addresses keep their hashed public key, offering an additional layer of protection<\/strong> even against a quantum adversary<\/strong>.<\/p>\n\n\n\nThe Bitcoin community actively monitors quantum developments. Several developers are working on experimental implementations of post-quantum cryptography compatible with the network architecture. The question is no longer about “if” but “when” and “how” this major technological transition<\/strong> will occur.<\/p>\n\n\n\n\n
