A well-known crypto researcher claims that Bitcoin, Ethereum, and $XRP are vulnerable to quantum threats, but $XRP may have an advantage over the others. Discussions about the impact of quantum computing on blockchain security have intensified as researchers assess whether future quantum machines could crack the cryptographic systems used by major networks. After studying these potential risks, Versan Aljarra, founder of Black Swan Capitalist, recently explained that Bitcoin, Ethereum, and $XRP use cryptographic methods that could theoretically become vulnerable if quantum computing advances far enough. Although none of the networks are fully protected against the growing quantum threat, Aljarra suggested that $XRP might have an edge due to how the original developers structured the $XRP XRPL( ledger.
