Quantum computing has advanced from being a distant theoretical threat. Now, it shapes how the crypto industry plans its infrastructure for the decades ahead.
Coinbase, Ethereum, and the Ethereum Layer 2 network Optimism are publicly laying out timelines, governance frameworks, and migration strategies to prepare for a post-quantum future. This highlights a stark contrast with Bitcoin, which remains constrained by its decentralized coordination model.
The Quantum Countdown Has Begun: Which Blockchain Will Survive the Future Attack?
Coinbase CEO Brian Armstrong announced the formation of an independent advisory board dedicated to quantum computing and blockchain security.
The board brings together leading researchers in cryptography, consensus, and quantum computing, including Stanford’s Dan Boneh, UT Austin’s Scott Aaronson, Ethereum Foundation’s Justin Drake, and EigenLayer’s Sreeram Kannan.
Ethereum, meanwhile, has framed quantum resistance as an engineering and migration challenge. Its ecosystem treats post-quantum security as a concrete problem to be solved through timelines, hard forks, and account abstractions.
The network’s post-quantum roadmap includes a 10-year plan to deprecate ECDSA-based externally owned accounts (EOAs) across the Superchain by 2036.
