Recent research combining blockchain and quantum computing has accelerated, raising concerns about cryptocurrency security and consensus mechanisms. Quantum computers threaten to break traditional encryption like RSA and ECDSA, potentially compromising wallet security and transaction integrity. Consensus mechanisms like Proof of Work could also be disrupted due to quantum speedup. Projects like Quantum Resistant Ledger (QRL) counter this by using XMSS, a hash-based signature scheme resistant to quantum attacks, ensuring long-term security. QRL’s multi-algorithm mining enhances decentralization, while its adaptability positions it as a leader in quantum-resistant blockchain technology, safeguarding cryptocurrencies against emerging quantum threats.
