What to know:
- The CZ Bitcoin freeze proposal could target up to 1 million dormant Satoshi-linked coins.
- Zhao proposed a six- to twelve-month migration window before legacy addresses retire.
- Critics say freezing dormant Bitcoin could conflict with ownership and immutability.
The CZ Bitcoin freeze proposal was raised by Binance founder Changpeng Zhao for up to 1 million dormant coins linked to Satoshi Nakamoto. He said it could follow a future quantum-resistant upgrade. Any change would require support from the Bitcoin community.
Zhao made the comments during the Galaxy Brains podcast hosted by Alex Thorn on June 18. Quantum computing is not an impractical threat to Bitcoin. According to Zhao, quantum-resistant cryptographic systems already exist.

CZ Bitcoin Freeze Proposal Sets Quantum Migration Window
He said a network-wide migration was the greater challenge. It may be required if quantum computers take down Bitcoin’s security. Users would transfer money to addresses that were protected.
The CZ Bitcoin freeze proposal is targeted towards wallets that have not been used for years. Among these are addresses that are widely thought to belong to the pseudonymous creator of Bitcoin. Zhao proposed a window of about 6 to 12 months for migration.
Holders had the option to move money to upgraded addresses during that time. After the deadline, legacy addresses would be phased out. Under the updated protocol, coins that remained untouched could be frozen.
The CZ Bitcoin freeze proposal might prevent quantum attackers from obtaining balances. The inactive owners might not be available to secure the money. If no action is taken, the first party to crack an address will be able to take its coins.
Zhao referred to that result as an “unfair distribution of Bitcoin. It would reward technical ability, not the original owner. Zhao said no individual should make that decision.
The CZ Bitcoin freeze proposal will require community approval. Changes to Bitcoin are dependent on the consensus of the network participants. It is not a protocol-adopted idea.
Coinbase Advisory Board Examines Bitcoin Quantum Risks
Coinbase’s advisory board also issued a report in June that advised for preparation in advance. They said quantum computers are not yet a threat to Bitcoin. If the threat changes, planning ahead could minimize disruption.
The report was prepared with the help of Ethereum Foundation researcher Justin Drake. It specified a schedule for the migration of ECDSA and Schnorr-protected coins. The goal of the plan was to minimize threats associated with legacy cryptography.
According to sources cited in the report, the CZ Bitcoin freeze plan may prevent large-scale theft. They said that unmigrated addresses might provide significant holdings to attackers. This outcome may have an impact on market stability as well.
Critics rejected making dormant coins unspendable. They said a freeze might be the equivalent of a confiscation of private property. It might also be in opposition to Bitcoin’s rules of immutability and consumer control.
Thorn has been a leading critic of freezing inactive wallets. He has stated that in May, Satoshi’s coins should be left alone regardless of technological advancements. He said many Bitcoin developers and advocates share that view.
The CZ Bitcoin freeze proposal is a theoretical response to a future concern. Bitcoin has not adopted a post-quantum migration plan or set a deadline. This problem is related to security, ownership rights, and network governance.
