XRP Ledger Targets Quantum-Resistant Upgrade by 2028
The XRP Ledger Foundation has proposed an upgrade to protect XRP accounts and network validators against future quantum computing attacks. The research, published as part of the XRP Ledger Foundation’s 2027 protocol roadmap, details the technical requirements, costs, and potential challenges of adopting quantum-resistant cryptography. The upgrade would allow users and network operators to replace existing cryptographic keys with alternatives designed to withstand attacks from sufficiently powerful quantum computers.
