In an insightful note on Ethereum's resilience to quantum computing attacks, Vitalik Buterin, the co-founder of the Ethereum project, has expressed his confidence in the blockchain's ability to withstand such futuristic threats. Highlighting the minimal potential damage a quantum hack could inflict, Buterin underscored the readiness of infrastructure to shield the network, which, according to him, could be deployed "as early as tomorrow."

Buterin shed light on the looming threat of quantum computing attacks on blockchain technology. He reassured the community that Ethereum could be fortified against this menace "by tomorrow." This bold statement is backed by Ethereum's capacity for executing a hard fork to address and mitigate the situation promptly. Buterin emphasized that deploying the update and users downloading new software are feasible steps, ensuring negligible harm.

As a testament to post-quantum cryptography (PQC), Buterin cited the Winternitz One-Time Signature (W-OTS) scheme and STARK technology as examples. He elaborated that the upcoming abstraction of account models would allow any Ethereum user to switch to it, effectively safeguarding against quantum attacks. The initial phase of the hard fork, according to Buterin, would involve rolling back the blockchain to a pre-hack state. Subsequently, it's crucial to disable traditional EOA-based transactions in favor of those based on the RIP-7560 solution.

Buterin also recommended employing STARK-based zero-knowledge proofs. According to him, the blockchain infrastructure necessary for such a hard fork could start being rolled out "as early as tomorrow."

This development comes on the heels of major tech corporations forming a coalition to promote post-quantum cryptography, signaling a growing industry awareness and readiness to confront quantum computing challenges.

The threat posed by quantum computers capable of breaking Bitcoin and Ethereum level blockchains has been a topic of discussion for some time. For instance, reports from China in January 2023 highlighted such capabilities. However, even with a high-powered quantum computer exceeding 10,000 qubits, experts consistently point out that breaking into these blockchains would require a considerable amount of time, underscoring the theoretical nature of this threat at present.

Buterin's proactive stance and proposed measures underline Ethereum's commitment to security and innovation, aiming to stay ahead of potential future challenges in the fast-evolving landscape of blockchain technology and quantum computing.
