XRP Ledger Outlines Zero-Fee Plan Shielding Accounts From Quantum Computing

TL;DR Quantum Security: XRP Ledger is exploring a quantum-resistance upgrade that would allow account holders to add a new quantum-secure signing key. Zero-Fee Approach: The proposal uses the ML-DSA-44 signature scheme approved by NIST in 2024. Protected transactions would require more storage space. Development Roadmap: Development work is ongoing, including compatibility fixes and validator testing. The quantum security initiative is part of the Foundation’s roadmap. The XRP Ledger Foundation has outlined a proposal designed to protect user accounts from future quantum computing threats without increasing transaction costs . Included in the network’s updated roadmap, the plan would allow users to adopt a quantum-resistant signing method and deactivate their existing key. The initiative aims to address a long-term security risk that could emerge once sufficiently powerful quantum computers become available.
