Can Quantum Computing Break Blockchain?

Hey, I keep hearing that quantum computing could eventually break blockchain security. Is this a real threat, and what’s being done to future-proof cryptocurrencies?

Re: Can Quantum Computing Break Blockchain?

It’s a legit concern! Quantum computers could theoretically crack current encryption methods (like SHA-256), putting Bitcoin and other blockchains at risk. But projects are already working on solutions—like quantum-resistant algorithms and new consensus mechanisms. I found this clear explainer on how Quantum Coin and other initiatives are tackling the problem: https://salaryslip.org/quantum-coin-ensuring-blockchain-integrity-in-the-age-of-quantum-computing/ . It breaks down the tech in plain language and highlights how crypto might evolve to stay secure. Super timely read!
