XRP Ledger AlphaNet Tests Quantum-Resistant Security Upgrade

• XRPL AlphaNet now tests post-quantum security across accounts, transactions, and validator consensus.
• The network replaces elliptic curve cryptography with NIST-standardized Dilithium signatures.
• A separate proposal explores optional one-time key rotation to limit quantum attack windows.

The XRP Ledger closed the year with an update after its public developer network, AlphaNet, activated a suite of quantum-resistant features alongside native smart contract support. The changes, confirmed on Dec. 24 by XRPL Labs engineer Denis Angell, mark one of its key security changes tested on the network to date.

According to Angell, AlphaNet now operates using post-quantum cryptography across its core components, including accounts, transactions, and validator consensus. The update introduces what the development team refers to as Quantum Accounts, Quantum Transactions, and Qu…
