KuCoin security update includes new quantum-resistant features on the XRP Ledger AlphaNet, as reported by CoinEdition. The network now uses NIST-standardized Dilithium signatures instead of elliptic curve cryptography. XRPL Labs engineer Denis Angell confirmed the change on Dec. 24, introducing Quantum Accounts, Transactions, and Consensus. The upgrade targets 'Q-Day' risks from quantum computing. KuCoin security efforts also include a proposal by Edward Hennis for optional one-time key rotation to reduce attack windows.

Citing CoinEdition, the XRP Ledger's AlphaNet has activated quantum-resistant security upgrades, replacing elliptic curve cryptography with NIST-standardized Dilithium signatures. The update, confirmed on Dec. 24 by XRPL Labs engineer Denis Angell, introduces Quantum Accounts, Quantum Transactions, and Quantum Consensus, all based on lattice cryptography. The changes aim to address the 'Q-Day' risk, where quantum computers could break traditional encryption. Separately, a proposal by developer Edward Hennis explores optional one-time key rotation to further limit quantum attack windows.
