Popular XRPL dUNL validator Vet expresses confidence in the $XRP Ledger community’s ability to coordinate a quantum-resistant hard fork.
At the same time, he questioned whether the Bitcoin ecosystem could achieve the same outcome.
Key Points
- XRPL dUNL validator Vet argues that the $XRP Ledger can coordinate a quantum-resistant hard fork, while casting doubt on Bitcoin’s ability to achieve the same.
- He emphasizes that Bitcoin’s biggest obstacle lies in social coordination rather than technical limitations.
- Vet expresses strong confidence in XRPL’s willingness and ability to implement upgrades that strengthen network security.
- A recent Google report warns that advanced quantum systems could eventually break encryption standards widely used across major cryptocurrencies.
“XRPL Can Coordinate Quantum-Resistant Hard Fork, Not Bitcoin”
In a series of tweets, Vet joined the growing debate about how advances in quantum computing could affect blockchain security and potentially allow attackers to compromise existing cryptographic systems.
He raised doubts about whether the Bitcoin community could successfully coordinate a quantum-resistant hard fork if emerging technologies begin to threaten current cryptographic standards.
He argued that the challenge would likely be social rather than technical. In his view, reaching agreement across Bitcoin’s decentralized ecosystem could prove difficult because the network has a long history of contentious governance debates.
In contrast, Vet expressed strong confidence that the $XRP Ledger (XRPL) could implement a similar upgrade more smoothly. He explained that the network relies on a tradition that enables validators to introduce and adopt protocol improvements.
Concerns About Quantum Threat Accelerate
Meanwhile, the commentary comes amid a recent Google report that suggests that rapid advances in quantum computing could eventually give malicious actors tools to break widely used encryption methods.
Notably, most cryptocurrencies, including Ethereum, Bitcoin, and the $XRP Ledger, rely on Elliptic Curve Digital Signature Algorithm (ECDSA) to secure transactions and verify asset ownership.
According to a Google report, a sufficiently powerful quantum computer running an optimized version of Shor’s algorithm could theoretically break 256-bit ECDSA encryption in minutes, raising alarms across the crypto industry.
Binance’s CZ Proposes Solution, But Doubts Remain
Reacting, Binance founder Changpeng Zhao (CZ) recently downplayed fears about quantum computing. He argues that cryptocurrencies can adapt by upgrading to quantum-resistant cryptographic algorithms if necessary.
Saw some people panicking or asking about quantum computing’s impact on crypto.
At a high level, all crypto has to do is to upgrade to Quantum-Resistant (Post-Quantum) Algorithms. So, no need to panic. 😂In practice, there are some execution considerations. It’s hard to…

Following his commentary, experts like Vet have begun questioning whether Bitcoin could coordinate a network-wide transition to quantum-resistant cryptography if such a threat becomes imminent.
While he doubts Bitcoin’s ability to reach consensus due to social constraints, he remains confident that XRPL validators would support upgrades designed to strengthen the network.
His commentary highlights a key difference between major blockchain ecosystems, particularly their approach to protocol governance. For context, Bitcoin prioritizes extreme stability and conservative upgrades, which can slow major changes and make achieving social consensus harder.
XRPL Quick Upgrade
By contrast, the $XRP Ledger has historically implemented amendments more frequently to improve efficiency, scalability, and security. For example, in February, security researcher Pranamya Keshkamat discovered a critical flaw in the network’s proposed batch amendment that could have allowed attackers to drain users’ $XRP.
After identifying the issue, the researcher alerted XRPL Labs before the upgrade went live. In response, the development team quickly urged dUNL validators to vote against the amendment. They also released an immediate patch to turn off the vulnerability and later deployed a corrected version of the upgrade.
Meanwhile, the $XRP Ledger has taken proactive steps to counter the quantum threat, including early testing of post-quantum ML-DSA signatures, deploying a test environment for quantum-resistant algorithms, and enabling built-in protocol-level key rotation.
