New paper highlights ‘Quantum-safe Bitcoin’ – Focus turns on XRP instead Bitcoin’s attempt to stay quantum-safe comes with a key limitation, prompting market attention toward other networks. If there’s one theme shaping the 2026 cycle so far, it’s that networks are starting to prioritize security. A week ago, Solana [SOL] ran a quantum-resistance test to evaluate whether the network could withstand quantum-related attacks. The key takeaway was a significant trade-off: about a 90% drop in speed in exchange for stronger security guarantees. Notably, other networks are now starting to follow suit. In the past two days, two major quantum-related updates came out for Bitcoin [BTC]. One prototype allows users to recover funds if quantum computers ever break current signature schemes. Now, a proposal by Avihu Levy suggests that Bitcoin transactions could be made quantum-safe without requiring changes to the core protocol. Interestingly, the latter has become the main focus among crypto enthusiasts. Levy released a whitepaper highlighting how Bitcoin transactions could become quantum-resistant without requiring a soft fork. That said, it doesn’t come without trade-offs. Notably, Bitcoin can be made quantum-safe today without a protocol upgrade, though each transaction could cost around $75 to $150 in GPU compute. Put simply, this means users would pay more in computing power and cost in exchange for stronger security without changing Bitcoin’s base protocol. In short, security for networks won’t come without trade-offs. First, Solana proved it with a 90% reduction in speed, and now Bitcoin with higher transaction costs. In this context, does this setup give a potential edge to networks that can better balance security with efficiency without pushing either cost or speed too far? Bitcoin’s quantum debate shifting attention toward XRP One clear signal from recent moves is that quantum threats are shifting from hype to a real concern. Why
