Coinbase is urging early work on Bitcoin’s post-quantum migration, while Binance prepares to close its mining pool and related services.
Bitcoin’s latest infrastructure discussion has two distinct fronts: preparing the protocol for a possible future cryptographic threat and adjusting mining operations after Binance’s decision to close its pool. Neither development changes Bitcoin’s rules today. Both underscore how much coordination a decentralized system depends on when its underlying technology or supporting services change.
In a technical paper published October 13, Coinbase urged Bitcoin developers to begin considering a multi-year migration to post-quantum cryptography before a cryptographically relevant quantum computer emerges. The company presented its paper as input to an ongoing discussion, not as a final position, deployment timetable or approved upgrade. Coinbase says it custodies about 5% of existing bitcoin, giving its assessment particular relevance to institutional custody, but that scale does not give the company authority to set Bitcoin’s protocol.
The paper identifies BIP-360’s P2MR design and a proposed P2TRv2 construction as flexible output formats that might make it easier to introduce or replace post-quantum signature systems without repeatedly redesigning transaction formats. Their status matters: BIP-360 remains a draft, and P2TRv2 is not an active Bitcoin upgrade and has no BIP of its own. Neither proposal represents a change accepted by Bitcoin developers or users.
Coinbase also describes a possible staged transition using a 1-of-2 hybrid construction. Under that approach, funds could be spendable either with a conventional ECDSA or Schnorr key, or with a post-quantum key. A hybrid design could offer a transition path, but the paper does not establish a selected implementation or resolve the trade-offs involved.
The company named ML-DSA, SLH-DSA and FN-DSA as algorithms for further evaluation, without endorsing one. Its paper also highlights requirements for institutional custody, including multiparty computation, hardware security modules, threshold signing and stateless signing. Those systems would need to accommodate any protocol changes while preserving the ability of independent participants to validate transactions—a core feature of Bitcoin’s decentralized design.
Coinbase separately flags dormant, lost or slow-to-move unspent transaction outputs as a policy question. The paper argues that this issue should not hold up upgrades for active wallets. That distinction points to a difficult governance problem: a migration plan must address not only new and active users, but also funds whose owners may not act promptly or at all. The paper does not settle how such coins should be treated.
Mining infrastructure faces a more immediate operational change. Binance announced October 13 that it will discontinue Binance Pool, Pool Savings, Cloud Mining, Transaction Accelerator, mining-pool APIs and related alerts at 07:00 UTC on November 10. Stratum URLs and mining endpoints will be disabled, and subsequent hashrate submissions and mining shares will not be accepted, processed or credited. Miners using the service must redirect their equipment to another pool before the cutoff.
Historical pool pages will remain viewable until 07:00 UTC on November 24. Binance cited an “ongoing review of products and services” but gave no more specific reason for the closure. The announcement does not indicate a change to Bitcoin’s mining protocol; it is a change in the services available to miners using Binance’s infrastructure.
Together, the developments illustrate different kinds of resilience. Post-quantum readiness would require gradual, technically sound coordination across wallets, custodians and the wider Bitcoin ecosystem. Binance’s closure, by contrast, calls for individual miners to choose alternative pool services. In both cases, the distinction between a company’s proposal or operational decision and a Bitcoin protocol change remains essential.
