Coinbase outlines priorities for protecting Bitcoin from quantum computers
Coinbase has outlined priorities for a plan to protect Bitcoin from quantum computers.
The exchange wants the design to let developers add or replace post-quantum signature systems without changing how coins are held.
It also supports a staged transition that could let users spend with either a traditional key or a quantum-safe key.
The plan should work for ordinary wallets and institutional custody, including systems that split keys among several parties.
Coinbase says work should begin before a quantum computer can break current cryptography, and late-moving wallets should have a migration path.
The approach would separate upgrades from decisions about old vulnerable coins, including holdings linked to Bitcoin creator Satoshi Nakamoto.
Those coins may be impossible to move if their private keys are lost, and the community is debating whether they should eventually be frozen.
Coinbase says its proposals are input to an open discussion, not final instructions; it wants protection available for people ready to upgrade while the wider community continues its work.
Coinbase has outlined features it would like to see in a plan to protect Bitcoin from future quantum computers.
The company favors a flexible design that would allow post-quantum signature systems to be added or replaced later.
It also supports a staged transition, early preparations and options compatible with institutional custody and ordinary wallets.
Coinbase says decisions about legacy funds with exposed public keys should be treated as a separate governance and engineering issue.
The company presented its proposals as input to an open discussion, not as instructions or a final position.
- Who

- When
- The blog post was published Tuesday; the article is dated October 16, 2026.
- Where
- The proposals appeared in a Coinbase blog post.
- Why
- A sufficiently powerful quantum computer could threaten vulnerable Bitcoin by breaking its security.
This story does not have two clearly opposing sides.
Concern has grown in the crypto world that a sufficiently powerful quantum computer could unlock vulnerable Bitcoin.
Coinbase’s quantum advisory board published a report on options for coins that are never moved to quantum-safe addresses.
Coinbase published a blog post outlining features it would like to see in a Bitcoin quantum-protection plan.

What people are saying
We believe a comprehensive transition strategy would ideally protect exposed and newly created funds, fit Bitcoin’s scarce block space, preserve independent resource-bounded validation by full nodes, work in institutional custody, support ordinary wallets, and give the ecosystem a credible migration path for coins that cannot or will not move.
In our view, legacy funds are best treated as a separate governance and engineering problem.
It is intended as an input to an open discussion, not a set of instructions or a final Coinbase position.
We want to contribute to the community’s efforts and help create the conditions for careful, sustained progress.
