Read U.TODAY on Google News Cryptographic security is again in focus as there is a claim that quantum computers are advancing rapidly, with severe consequences. Per the latest insights, Ethereum cofounder Vitalik Buterin has warned that quantum computing could decrypt elliptic curve cryptography in less than three years. Advertisement Quantum risk and need for new cryptography In a post on X, Solid Intel noted that at Devconect, an Ethereum developer event, Buterin charged developers to transition to quantum-resistant cryptography within the next three years in order to stay secure. This has become necessary because of rapid developments with quantum computers and their ability to crack systems. Notably, the "elliptic curve cryptography" is what secures several blockchain, such as Ethereum and Bitcoin. So, if quantum computers can decrypt these blockchains, it could spell doom for the cryptocurrency industry. As per Solid Intel’s claims, Buterin has warned that the ability of quantum computers to do this could happen before the 2028 presidential elections in the U.S. This gives developers a very tight timeline of less than four years to build quantum-resistant computers. INTEL: Vitalik Buterin warned at Devconnect that quantum computing could break elliptic curve cryptography before the 2028 U.S. presidential election, urging $ETH to transition to quantum-resistant cryptography within the next four years — Solid Intel 📡 (@solidintel_x) November 19, 2025 The Ethereum cofounder believes that this is the only way for blockchains to stay secure amid the rapid development of such computers. It implies that failure to transition to quantum-resistant cryptography could expose Ethereum to security risks. Primarily, cases of hacks could spike as perpetrators leverage quantum computers to compromise the Ethereum network and other blockchains. This might lead to the stealing of private keys to gain access to user funds. A malicious attacker might also forge transactions in order to spend someone else’s coin. Such a development could put investors’ funds at risk and affect confidence in decentralized finance. These threats make Vitalik Buterin’s warning very critical to ensure that the cryptocurrency industry stays ahead of the possible threats from quantum evolution.

Others in the crypto space have also urged developers not to treat the threat lightly. The overall assumption is that the timeline might be shorter than anticipated, hence the need for prompt action. Interestingly, in September 2025, Vitalik Buterin had, in a presentation at the Japanese Developer Conference, teased Ethereum’s future plans . Buterin had mentioned that Ethereum intends to build the most secure, future-proof network possible. He assured listeners that the plan is to do it without compromising the simplicity of the blockchain for users. #Ethereum
