The XRP Ledger moved part of its ecosystem into post-quantum testing in December 2025, when AlphaNet adopted NIST-approved ML-DSA. At the same time, validator data showed that only a narrow share of accounts face meaningful exposure today. Reports also said about 300,000 of 7.8 million accounts remain shielded because their public keys have never appeared on-chain.
But how ready is the broader network if quantum computing advances faster than expected?
Reports from an XRPL validator said roughly 300,000 accounts remain protected because they have never sent a transaction. Since those accounts never exposed a public key, an attacker has no visible entry point. Together, those shielded accounts hold about 2.4 billion XRP. By contrast, the rest of the network has visible public keys on-chain because those accounts have already transacted.
Traditional computers cannot break those keys today. Quantum machines with that power do not yet exist, either, yet the preparation window has already opened. Still, the validator data pointed to a narrow immediate risk. Only two dormant accounts with exposed public keys and no activity for more than five years hold significant balances.
Those two accounts together carry around 21 million XRP. That equals roughly 0.03% of XRP’s total supply, according to the same reports. As a result, dormant whale accounts with vulnerability remain rare. That pattern differs from Bitcoin, where large balances often sit in older pay-to-public-key wallets with exposed keys.
That contrast with Bitcoin extends beyond wallet exposure. On XRPL, users can rotate signing keys without changing wallet addresses.
That built-in key rotation gives holders a direct path to update security if quantum risks rise. Bitcoin does not provide that option natively.
The ledger also uses an amendment system. Under that process, validators vote on protocol changes, and the reported data said it moves faster than Bitcoin’s upgrade path. Bitcoin upgrades depend on miner consensus and often face slower, more contested rollout paths. XRPL’s structure, therefore, gives developers a clearer route for security changes inside the live ecosystem.
In December 2025, XRPL Labs developer Denis Angell said AlphaNet had adopted ML-DSA, also known as CRYSTALS-Dilithium. NIST has approved ML-DSA as a post-quantum signature standard.
AlphaNet also rolled out Quantum Accounts, Quantum Transactions, and Quantum Consensus. Those additions extended protection to validator communications as well as account activity.
Developers continue to build around future risk even as the present threat remains limited. They now combine key rotation with hybrid cryptography to test new signatures without opening security gaps.
That approach lets the network try quantum-resistant protections while it still uses traditional cryptography where needed. In turn, AlphaNet now handles transactions, accounts, and consensus with NIST-approved ML-DSA.
The developer testnet supports quantum accounts for fund storage, quantum transactions for access control, and quantum consensus for validator communications. Even so, those protections carry technical costs.

Quantum-resistant signatures take up far more space than older signatures. Reports said they are nearly 40 times larger, which increases storage needs and slows processing.
Engineers expect that pace to improve over time and eventually catch up with older models. Meanwhile, market behavior has started to reflect the broader security conversation.
The reports indicate whales bought more than 11 million XRP per day as the network takes proactive steps. Reports also note that large investors are moving XRP from exchanges into private wallets.
XRP traded around $1.37 in the same report, while market capitalization stood near $84 billion. Trading volume also rose sharply, reflecting stronger investor activity around the network’s security push.
XRPL’s AlphaNet adopted NIST-approved ML-DSA in December 2025, while validator data showed only limited near-term exposure across the network. With key rotation, hybrid cryptography, and quantum testing already in place, the XRP Ledger is building early defenses as market interest and whale accumulation continue to grow.
