Google’s recent research indicates quantum computers could potentially break Bitcoin’s cryptographic security within minutes. The report specifically highlighted three cryptocurrencies—Ethereum, Algorand, and Hedera—that may be positioned to safely navigate a post-quantum computing era due to their ongoing development of quantum-resistant technologies.
A recent paper from Google detailed how quantum computers could break cryptographic securities underpinning major digital assets. The research noted a quantum computer could break Bitcoin‘s private keys in approximately nine minutes, which is one minute less than Bitcoin’s average block time. This has prompted concerns among investors regarding the future security of cryptocurrency assets.
Ethereum has made progress toward becoming quantum-resistant, according to Ethereum Foundation researcher Antonio Sanso. He stated the project is 20% complete in this transition and has a clear plan to execute fully in the coming years. “The good thing is that we have been working on it for many months, if not years,” Sanso mentioned in an interview.
Algorand was specifically named in Google’s research for its readiness for a post-quantum computer world. The Algorand Foundation highlighted the coverage on social media, noting the project’s live post-quantum deployments across signatures, state proofs, and key rotation. The asset has seen substantial price gains following this development.
The third cryptocurrency cited as potentially safe is Hedera, which uses SHA-384 cryptography instead of Bitcoin’s SHA-256. SHA-384 is often cited as being quantum-resistant. Like Algorand, Hedera has also experienced a price rally recently. While these assets show promise, quantum computers are expected to grow more powerful, meaning projects may need to continue enhancing their security measures.
