Ripple reaffirms XRP as early XRPL wallets face quantum risk

Ripple CEO Brad Garlinghouse described XRP as the company’s ‘North Star’ and wrote that ‘all roads lead back to XRP.’ At the same time, an XRP Ledger validator known as Vet said a review of 7.8 million accounts found some early Genesis wallets that could be vulnerable to future quantum decryption.

Vet’s analysis found the majority of XRPL accounts remain protected. He identified roughly 0.02% of the total XRP supply as potentially exposed to an extremely powerful quantum processor and noted that about 23.16 billion XRP are “completely Quantum Safe. These accounts either rotate keys or never sign a transaction.” The validator added that roughly 300,000 Genesis wallets are receive-only and have not revealed signatures, which keeps those addresses resistant for now.

Vet encouraged users with exposed public keys to move funds to more secure wallets, rotate keys, or adopt quantum-resistant signature schemes. He wrote that “Dormant, vulnerable XRP whales are almost nonexistent,” and raised questions about how to treat inactive accounts whose assets might be at risk, including options to freeze, redistribute, or burn those funds.

XRPL developers say the ledger already includes mechanisms to migrate from classical elliptic-curve signatures to quantum-resistant algorithms. Teams plan to trial cryptographic standards recommended by the National Institute of Standards and Technology, run tests of new signature schemes on Devnet, and consider broader deployment if trials succeed.

A recent white paper from Google modeled how future quantum systems could break current cryptographic protections with fewer qubits and gates than earlier estimates. The analysis suggested a hypothetical 500,000-qubit machine could reduce the resources needed to attack ECDLP-256 by about 20 times. Researchers warned that some actors may be collecting public ledger data now with the aim of decrypting it later when quantum capability improves.

Google said it will continue research into post-quantum protections and work with industry and academic partners toward a 2029 timeline. The company also advised users to move funds out of exposed wallets and outlined policy options for handling abandoned or at-risk crypto assets.

Garlinghouse’s public remarks place XRP at the center of Ripple’s payments, custody, and institutional services. XRPL developers reported they are prepared to deprecate classical signatures and trigger a secure migration if traditional encryption becomes unsafe.
