Google has set a 2029 goal for transitioning to post quantum cryptography, accelerating its timeline as concerns about future quantum threats grow. However, many in the Bitcoin community remain unconvinced.
In a recent blog post, the company explained that the urgency is driven by two major risks. One is the so called store now decrypt later approach, where attackers gather encrypted data today with the intention of unlocking it once quantum computers become powerful enough. The other risk involves the potential of quantum machines to break digital signatures used for authentication, including those securing crypto assets.
Google said the updated timeline reflects rapid progress in quantum computing, including advances in hardware, error correction, and resource estimates for factoring.
Quantum Risks to Modern Cryptography
The company warned that quantum computing could pose a serious threat to current encryption systems and digital signatures. This has direct implications for networks like Bitcoin and Ethereum, which rely on these technologies for security.
Debate within the Bitcoin community has been ongoing. Some support upgrading to quantum resistant systems and allowing users to migrate voluntarily, while others argue that such changes could conflict with the principle that control of private keys determines ownership.
Investor Nic Carter expressed confidence that the network could coordinate updates and transition millions of addresses within a few years. Meanwhile, Vitalik Buterin has already introduced a roadmap aimed at making Ethereum resistant to quantum threats.
Investors Remain Calm
Despite the concerns, some industry leaders are not alarmed. Alex Thorn noted that while the threat is real, it is widely understood and not all wallets are currently at risk. He explained that funds become vulnerable mainly when public keys are exposed on chain.
Michael Saylor also downplayed immediate danger, suggesting that the industry would anticipate such developments and respond with coordinated upgrades across financial systems, internet infrastructure, and crypto networks.
A report from Ark Invest added that the threat is likely still years or even decades away. Researchers emphasized that current quantum systems lack the capability to break Bitcoin and that any meaningful breakthrough would first impact broader internet security, allowing time for adaptation.
They described the shift as a gradual technological evolution rather than a sudden event, giving markets and blockchain networks time to adjust. Google, however, appears to be taking a more cautious stance.#crypto#cryptonews https://coinsignals.net https://t.me/coinsignalpublic
