Ethereum and Optimism are proactively getting ready for a post-quantum future, launching long-term plans and funding to make sure the community can safely migrate its cryptography earlier than quantum computing turns into a actual menace.
Posted January 26, 2026 at 7:04 am EST.
The Ethereum Basis is taking concrete steps to guard the community in opposition to a threat most customers by no means take into consideration: quantum computing.
This week, the basis introduced a devoted post-quantum safety group, calling it a prime strategic precedence. The priority just isn’t fast. Massive-scale quantum computer systems don’t exist but.

But when they arrive earlier than blockchains are prepared, as we speak’s cryptography could possibly be damaged, placing wallets and transactions in danger. The onerous half just isn’t flipping a change. It’s coordinating upgrades throughout thousands and thousands of customers with out breaking something.
To get forward of that, Ethereum is transferring from analysis into execution. The inspiration is backing the effort with $2 million in analysis prizes, funding work on new cryptographic instruments and operating stay take a look at networks. The main target is easy: ensure that Ethereum can transition easily, with no lack of funds and no downtime, if stronger safety is ever wanted.
Senior researcher Justin Drake described the transfer as a prime strategic precedence, signaling a shift from quiet analysis to energetic constructing.
The push displays a rising business consensus that preparation issues greater than timing. As soon as a menace turns into pressing, it’s already too late to begin planning.
Optimism took a equally long-term view.
On Sunday, Optimism announced a 10-year roadmap to part out as we speak’s customary pockets signatures throughout its Superchain (which hosts many layer 2s, together with Coinbase’s Base).
By 2036, conventional pockets keys might be changed by good accounts that may help post-quantum safety, with out forcing customers to alter addresses or transfer funds. The plan depends on gradual upgrades, clear timelines, and coordinated hardforks slightly than ushed fixes.
OP additionally stated its infrastructure, together with sequencers, will transfer away from present signatures, and that it’s working carefully with Ethereum on shared requirements.
The message from each ecosystems is the identical: quantum safety just isn’t a disaster but, however migration takes time, and the clock solely begins when builders determine to behave.
