A prominent crypto founder says Bitcoin, Ethereum, and $XRP all suffer quantum threat risks, but $XRP may have an advantage over the others.
Discussions about the impact of quantum computing on blockchain security have picked up the pace as researchers assess whether future quantum machines could break the cryptographic systems used by major networks.
After studying these potential risks, Versan Aljarrah, founder of Black Swan Capitalist, recently explained that Bitcoin, Ethereum, and $XRP all rely on cryptographic methods that could theoretically become vulnerable if quantum computing advances far enough.
While none of the networks have full protection against the growing quantum threat, Aljarrah suggested that $XRP may have an advantage because of how the original architects structured the $XRP Ledger (XRPL).
Key Points
- Versan Aljarrah argued that Bitcoin, Ethereum, and $XRP are not currently quantum-proof because they rely on elliptic curve cryptography, which a powerful quantum computer could theoretically break.
- He warned that if quantum computers reach that capability, the impact could extend to systems like global banking networks, SWIFT, military encryption, and parts of the internet.
- Aljarrah argued that updating the cryptography in Bitcoin or Ethereum would require complex upgrades or hard forks, which could destabilize their networks.
- He explained that the $XRP Ledger can upgrade its cryptography through validator consensus at the protocol level without disruptions and long debates, giving it an edge over Bitcoin and Ethereum.
Why Quantum Computers Could Be a Problem for Blockchains
The Black Swan Capitalist founder made these comments while speaking on X. According to him, modern blockchains depend on a security method called elliptic curve cryptography.
For context, this mathematical system protects digital assets by using two keys. Specifically, the public key is visible on the network, while the private key remains secret and allows the owner to access and control their funds.
Over the last few weeks I’ve been researching quantum computing risk across blockchains, and here’s what I found.
The short answer: no blockchain today is fully quantum proof, not Bitcoin, not Ethereum, not $XRP.

Aljarrah explained that the concern comes from the possibility that a powerful enough quantum computer could eventually break this type of encryption. If this happens, attackers could potentially figure out private keys from public ones, which would give them access to digital wallets.
He also stressed that the risk would not stop at cryptocurrency. Notably, if quantum computers reach that level, they could threaten many other systems that rely on similar cryptography. Global banking networks, SWIFT, military encryption, and large parts of the internet could also face serious security issues.
Why $XRP Could Adapt Faster
While all major blockchains share this vulnerability, Versan Aljarrah believes $XRP has a design that could make it easier to respond if quantum computing becomes a real threat. He pointed out that the cryptographic systems used by Bitcoin and Ethereum are deeply built into their networks, which makes major changes difficult.
Aljarrah said updating the cryptography behind Bitcoin or Ethereum would likely require major upgrades and hard forks. These changes often involve long debates and coordination among developers and community members, which can slow the process and create risks for the network.
However, the $XRP Ledger works differently. Aljarrah explained that the network operates through a protocol-level governance system. This allows validators to approve cryptographic upgrades through consensus without shutting down the network. As a result, the system could adjust in real time if new security standards become necessary.
He also noted that Bitcoin developers built the network to be rigid, while Ethereum upgrades often move slowly and involve complicated changes. However, he called $XRP a financial infrastructure designed to adapt to new challenges while continuing to process transactions.
XRPL’s Crypto-Agility Feature
Responding to Aljarrah, James Dula, another pundit, explained that the XRPL already has a built-in approach for handling cryptographic changes. For context, this refers to its crypto-agility feature, which allows validators to switch to new security standards if the current ones ever become unsafe.
Dula said validators on the XRPL can vote to upgrade the signing algorithm across the entire network through consensus. This would not require a hard fork, a network shutdown, or the type of community conflict that often happens in the Bitcoin ecosystem when major changes are proposed.
He also pointed to developments from the National Institute of Standards and Technology (NIST), which introduced its first post-quantum cryptographic standards in 2024. These standards include algorithms known as CRYSTALS-Kyber and CRYSTALS-Dilithium, both based on lattice-style cryptography for resisting attacks from quantum computers using currently known techniques.
According to James Dula, the $XRP Ledger could adopt these algorithms through validator consensus whenever they become necessary. In contrast, he argued that implementing similar upgrades on Bitcoin would require a hard fork that could split the community.
