Cryptocurrency networks can move to post-quantum cryptography only through a coordinated protocol, wallet, and governance transition—not by asking users to change a setting. The network must learn to validate new authorization methods, wallets must let people control and spend funds with them, and users need a safe way to move or update their accounts. The hardest question is what happens to coins whose owners cannot or do not migrate, especially if their keys are exposed.
What post-quantum migration is—and what it protects
Post-quantum cryptography (PQC) means classical cryptographic algorithms designed to resist attacks from both conventional and sufficiently capable quantum computers. It is not the same as quantum cryptography. For cryptocurrency, the principal concern is authorization: many systems use public-key signature schemes to prove that a transaction was approved by the holder of a private key. A sufficiently capable quantum computer could threaten some of those schemes and, in turn, the security of funds controlled by them.
That does not mean every part of a blockchain would fail in the same way. Hash functions are affected differently by quantum computing and are less susceptible than public-key signature schemes, though they can also be weakened. The migration question is therefore not simply “replace encryption.” Networks need to identify which cryptographic operations are used, where they are used, and which changes are necessary to preserve authorization and system security.

Changing a wallet app alone cannot make a network accept a new signature. The network’s validation rules must support the new authorization method, and wallet software must be able to create and manage the credentials needed to use it. A migration therefore involves protocol developers, node and wallet implementers, users, and the governance process that coordinates a change.

Why networks need a plan before a quantum threat is imminent
No cited source establishes when a cryptographically relevant quantum computer will be built. NIST says predictions vary widely and that no one knows how long development will take. It also notes that turning a new cryptographic algorithm into a standard and integrating it broadly into information systems has historically taken 10 to 20 years; that is a general observation about information systems, not a prediction that any particular blockchain migration will take that long.
NIST finalized its first three post-quantum cryptography standards on August 13, 2024, after an effort it describes as lasting eight years. NIST encourages organizations to start applying the standards. They offer a foundation for implementation, but they do not automatically upgrade cryptocurrency protocols or prescribe one universal migration for every chain. NIST’s transition report, NISTIR 8547, is a draft plan for federal agencies, industry, and standards organizations—not a binding deadline for public blockchains.
NIST’s guidance offers a useful planning sequence: find vulnerable cryptography, prioritize what needs to change, make a roadmap, and test interoperability. For a blockchain, that work must also answer how the network will activate new validation rules, how holders will use new credentials, and what treatment applies to old funds. NISTIR 8202 notes that a major cryptographic change may require a fork depending on the flaw’s significance, and that partial adoption can leave vulnerabilities. A hard fork is not universally required: programmable authorization and account-abstraction approaches may provide other paths, subject to each network’s protocol design.

What a safe migration has to coordinate
Choose and implement a supported authorization method
A network needs a post-quantum signature-verification method that its protocol can validate. Choosing an algorithm is only the start: implementations must be integrated into transaction and consensus rules, and developers need to understand how the change affects the network’s existing authorization model. The cited material does not establish one algorithm or signature format that all cryptocurrency networks should adopt.
Define how the network activates the change
Protocol designers must decide how old and new transaction rules coexist, what upgrade mechanism enables validation, and how the network handles transactions that use each form of authorization. The exact activation process depends on the chain. Depending on the significance of the cryptographic issue, an upgrade could involve a fork; some account-based designs may evolve authorization differently. It would be misleading to treat any single activation method as a universal requirement.
Give holders a usable path to new credentials
Wallets need to generate, store, and use the new credentials, and explain what action—if any—the holder must take. A plan should make clear whether the user changes authorization for an existing account, creates a new one and transfers funds, or follows some other network-specific process. Until the network validates the new method and wallets support it, the ability to create new credentials is not enough to protect funds on that network.

Test implementations together and communicate clearly
Nodes, wallets, and other software that handles transactions must interoperate. Developers need to test that the new authorization can be created, relayed, and validated consistently, and that the upgrade behaves as intended alongside the existing rules. NIST identifies interoperability as part of migration planning. The sources reviewed do not quantify the resulting transaction-size, validation, fee, or performance costs for particular networks; those need to be evaluated for each design.

1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesFinally, the network needs to communicate the change in terms holders can act on: which accounts are affected, what a wallet will show, what the migration deadline or restriction means if one exists, and what happens to funds that remain on old authorization. A technically sound upgrade can still leave users at risk if wallets do not support it or instructions are unclear.
How to assess a proposed migration plan
Before treating an announcement as protection for your holdings, check whether it describes an implemented network change or only a proposal or roadmap. These questions help distinguish a complete migration plan from an algorithm announcement:

- Compatibility and activation: Does the plan explain how old and new transaction rules coexist and what protocol upgrade activates validation?
- Holder migration: Does it say what a wallet owner must do, whether the account can change authorization directly, and whether one action covers the account’s assets?
- Legacy funds: What happens to dormant, lost, or already-exposed keys? Is there a recovery mechanism, and what limits or ownership questions does it create?
- Operational impact: Does the plan discuss transaction data, validation, fees, and wallet support? The available sources establish that implementation matters but do not provide comparable cost figures for particular chains.
- Coordination: Who will implement and review the change, how will it be activated, and how will adoption and user readiness be communicated?
Ethereum: account-level signature agility is a roadmap consideration
Ethereum’s roadmap page, last updated September 8, 2026, describes account abstraction as a possible route to signature agility: an individual account could switch signature schemes without waiting for a single, protocol-wide signature migration. The page identifies EIP-8141 as being considered for Hegotá in the second half of 2026. This is a roadmap consideration, not an activated feature or a guaranteed fork commitment. Its timing and details may change.
The account-level idea matters because Ethereum assets are controlled by account signatures. If an account’s signature scheme is migrated, the assets controlled by that account can be protected together; a holder would not necessarily need to move every token or NFT separately. That does not eliminate every dependency: a smart contract may use vulnerable cryptographic primitives internally and need its own upgrade. Nor does a roadmap remove the need for wallet support and a clear user migration process. Ethereum’s roadmap says wallet software is expected to guide future migration, and also states that no blockchain has completed a full post-quantum transition.

Bitcoin: BIP 361 is a proposal, and dormant coins remain unresolved
BIP 361, titled “Post Quantum Migration and Legacy Signature Sunset,” is a proposal—not an adopted Bitcoin protocol change. It discusses migration, restrictions on legacy signatures, and possible rescue protocols. Its existence does not establish a Bitcoin migration deadline, an implemented rescue feature, or a settled consensus change.
The proposal highlights the conflict around exposed public keys and coins that have not moved. It describes a possible rescue concept based on knowledge of a hardened BIP-32 parent extended private key. That is a proposal, not proof that a particular inactive balance can be recovered. The document says it remains unknown how much of the legacy supply a rescue protocol could cover.
This is as much a governance problem as a cryptographic one. If old signatures remain spendable after they become vulnerable, an attacker may be able to take funds. If old spending is restricted to protect them, legitimate holders—including people who have lost access to a key or cannot complete a migration—could be unable to spend. A rescue method also has to establish who can prove the right to move a coin without giving someone else a way to claim it. The cited proposal does not resolve that trade-off for all dormant funds.

There is no universal user-side migration step that applies across networks, and no wallet setting can substitute for protocol support. While a network’s plan is developing, holders can make the eventual transition more manageable without assuming a migration has already occurred:
- Follow official network and wallet announcements. Look for the status of the change—proposal, roadmap consideration, activation, or implemented support—and for instructions specific to your network and wallet.
- Keep control of the credentials your assets depend on. A proposed rescue or migration should not be treated as a replacement for access to your own keys. Do not assume a third party can recover a dormant balance.
- Check what an upgrade actually covers. Account-based migration may cover assets controlled by an account, while a contract may have separate cryptographic dependencies. Other networks may require a different process.
- Wait for compatible network and wallet support before acting on migration instructions. A new key or address by itself does not change the authorization rules a network accepts. Use instructions issued for the actual upgrade rather than guessing at a transfer or deadline.
- Ask how old funds are treated. If a plan restricts legacy signatures or proposes recovery, understand whether inactive funds could become unspendable and what proof of ownership is required.
What is known—and what remains open
The direction of the work is clear: identify vulnerable uses of cryptography, standardize and implement suitable alternatives, update network rules and wallet support, test interoperability, and coordinate adoption. The unresolved details are network-specific. The cited sources do not establish a settled cross-network standard, a final Ethereum deployment, Bitcoin adoption of BIP 361, a reliable date for a cryptographically relevant quantum computer, or a recovery mechanism that can safely restore every inactive balance.
For users, the practical distinction is between a plan and protection already available on the network. NIST standards make implementation possible; they do not migrate coins. A roadmap or proposal can explain how developers are thinking about the problem; it does not prove that holders’ current credentials have been replaced or that lost funds can be rescued. A successful transition has to protect spendable funds while making the path—and the consequences for funds that do not move—understandable to their owners.
