Amid ongoing discussions about whether quantum technology could threaten blockchain security, Vet, a validator on the XRP Ledger, said Bitcoin may be more exposed to future quantum risks than XRP.
Vet pointed to on-chain activity patterns among XRP accounts. He said about 300,000 XRP accounts, holding roughly 2.4 billion XRP, have never made outgoing transactions. Because these wallets have only received funds, their public keys have not been exposed on-chain, which he described as theoretically more secure against quantum attacks.
He also highlighted that just two long-inactive accounts hold around 21 million XRP, with their public keys exposed. Vet said this is only about 0.03% of the total supply, suggesting that vulnerable dormant XRP wallets are extremely rare.
Vet said that while most active XRP accounts have exposed keys, users can still change or “rotate” their keys if needed. He contrasted this with Bitcoin, which he said may face higher theoretical risk due to a larger number of dormant coins and older transaction formats that can expose public keys.
“Your XRP is safe. There are no known quantum computers capable of threatening public blockchains today. By the time that changes, the industry will have found a solution,” he stated.
The broader discussion has gained momentum following recent research from Google. According to its researchers, a quantum computer may need fewer than 500,000 physical qubits to break the cryptographic security of Bitcoin and Ethereum—about 20 times less than earlier estimates.
In experimental simulations, Google tested circuits using between 1,200 and 1,450 logical qubits, requiring tens of millions of quantum gates. Under standard assumptions, the computation could take between 9 and 12 minutes, potentially within Bitcoin’s 10-minute block time.
The findings raise the possibility of an “on-spend attack,” a theoretical scenario in which an attacker could derive a private key from a publicly revealed key during a transaction window.
In response to long-term quantum risks, the Ethereum Foundation has begun preparing the network for a post-quantum future, with major upgrades targeted for 2029.
Its roadmap includes protocol upgrades designed to strengthen security across multiple layers. These include introducing backup validator keys for emergency scenarios, reducing verification costs for quantum-safe signatures, and implementing advanced techniques such as zero-knowledge proofs to securely compress blockchain data.
The plan also calls for replacing current signature schemes with post-quantum alternatives, along with new methods to maintain efficiency despite increased cryptographic overhead. Additional measures aim to secure layer-2 networks and improve data storage resilience.
Developers estimate that truly “cryptographically significant” quantum computers may still be 8 to 12 years away, and the foundation emphasized the need to act early.
Despite rising attention, experts broadly agree quantum threats remain a long-term concern rather than an immediate danger. For now, networks including Bitcoin, XRP, and Ethereum continue to operate securely, while preparation for a quantum future continues.
Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
