Resumo

Litecoin's cryptographic foundation relies entirely on secp256k1 elliptic curve cryptography, which is vulnerable to quantum attacks via Shor's algorithm. When large-scale quantum computers become available, all digital signatures and public key derivations will be breakable, compromising transaction security and wallet safety. Immediate planning for post-quantum migration is critical for long-term blockchain viability.
