Google recently published new research on blockchain quantum risks. In a release, Google warned that quantum advances could break the security of cryptocurrencies sooner than expected, emphasizing “appropriate urgency.”
The different quantum risk profiles of common blockchains were classified into four categories.
One category consists of protocols that cannot avoid long-term exposure of quantum-vulnerable public keys. This includes Ethereum, Solana, $XRP ledger. These utilize an account model and either use the public key directly as the account address or expose the public key in the first transaction.
of $XRP Ledger is notable for supporting native protocol-level key rotation, in contrast to other blockchains.

In recent tweets, $XRP Ledger Validator Vet highlighted Google’s findings on quantum risks of various blockchains.
oh! ! Today is quantum day! Google has published new research on quantum risk in blockchain.

$XRP Ledger is currently testing quantum resiliency. Last December, the XRPL Alpha testnet (AlphaNet) integrated dilithium-based encryption. This represents the starting stage for building quantum resistance.
Other deductions shared by veterinarians include: $XRPNative key rotation feature for accounts, unlike ETH and Solana. Google discovered that there are far fewer physical and logical qubits than expected that can destroy a public blockchain, and that less than 9 minutes is enough to attack Bitcoin.
Similarly, key rotation alone can be seen in the following cases: $XRP Ledger — May not be sufficient protection as submitted signatures can be attacked.
Although XRPL is not currently fully quantum-proof, it is laying the foundation for future upgrades to post-quantum cryptography standards to protect against potential future threats.
Vet noted that all cryptocurrencies that are not quantum resistant are affected by this threat, regardless of whether they are mentioned by name or not. He added that key rotation alone will no longer be viable, as seen in the Bitcoin example. Development is accelerating, and changes to quantum protocols are probably happening faster than expected.
