The debate around the network's historical funds comes to the fore after a statement from Changpeng Zhao. The founder of Binance raised the possibility of blocking some of Satoshi Nakamoto's bitcoins in the face of the risk linked to quantum computing. CZ, however, presented this idea as a question for the community, not as a personal initiative.
In brief
- CZ relaunches the debate on a possible freezing of bitcoins associated with Satoshi Nakamoto in the face of the risk linked to quantum computing.
- The founder of Binance does not propose a seizure, but questions the community about possible protection of vulnerable addresses.
- Quantum computers could pose a future threat to some wallets whose public keys are already exposed.
- Satoshi bitcoins remain at the center of discussions, as their blocking could set a precedent contrary to the principles of decentralization of the network.
- The challenge for Bitcoin will be to find a balance between security in the face of new technologies and respect for the fundamental rules of the protocol.
CZ opens debate on possible freezing of Satoshi's bitcoins
CZ raised this possibility during an exchange with Alex Thorn, director of Galaxy Research, on the Galaxy Brains podcast. The founder of Binance did not present this idea as a decision made, but as an open question aimed at members of the ecosystem.
After this statement, CZ denial rumors claiming that he “ could personally block the address linked to Satoshi Nakamoto for a given period » . He explained that this interpretation did not correspond to his words.
The former Binance executive did not call for a seizure of funds. Instead, he raised the idea of a deadline after which cryptocurrencies present on addresses deemed vulnerable could be blocked by a modification of the protocol.
CZ notably asked the community a question:
Why not allow a period of around a year before applying any possible measure against exposed addresses?

According to this approach, the funds concerned could be protected by an evolution of the network. This proposal, however, raises a major difficulty. CZ acknowledged that it remains complex to precisely identify the wallets belonging to Satoshi Nakamoto among those used by the first Bitcoin miners.
This reflection is in line with certain technical proposals already discussed in the ecosystem. The BIP-361 proposal notably provides for mechanisms to gradually limit the risks associated with vulnerable addresses and exposed signatures.
Furthermore, he also called for caution regarding the quantum threat. Its approach is based on the idea that the network must anticipate future risks without ignoring the consequences of a significant modification of its rules.
Quantum risk raises the question of dormant funds
The discussion launched by CZ is based on a specific technical concern: the possible evolution of quantum computers. These technologies could, ultimately, make it possible to find private keys from already exposed public keys.
The danger mainly concerns wallets whose public keys appear on the blockchain. An attacker equipped with sufficiently advanced technology could then attempt to recover the funds associated with these addresses.
In March, a study conducted by Google Quantum AI reinforced concerns around this possibility. The researchers estimated that an attack could require fewer than 500,000 qubits and take place within minutes, lower than previous projections.
Faced with this threat, the Bitcoin network must consider an evolution towards cryptography resistant to quantum computing. However, such a transition requires significant coordination and several years of preparation.
THE data available in March indicated that more than a third of bitcoins had already revealed their public key on the blockchain. These addresses could therefore be exposed in the event of rapid evolution of quantum technology.
The issue becomes even more sensitive with the funds allocated to Satoshi Nakamoto. According to the estimate based on the Patoshi model, the creator of Bitcoin would have mined around 1.1 million BTC between 2009 and 2010. These holdings represent considerable value today and have remained unused since their creation.
Bitcoin: the dilemma between network security and respect for the founding principles
The debate around vulnerable addresses goes far beyond the technical question. It directly touches on one of the essential principles of Bitcoin: the ownership of funds must not depend on any authority capable of imposing a decision.
By this logic, bitcoins associated with Satoshi Nakamoto should not be frozen or modified. These holdings hold a special place in the network's history, as they represent the first mined blocks and the very origin of the protocol.
Intervention on these funds would set a major precedent. Bitcoin was designed to operate without central control, with identical rules for all participants. Allowing the blocking of specific addresses, even for a security-related reason, would call into question this fundamental logic and even be a betrayal of the original spirit of the network.
The risk would not only concern Satoshi's bitcoins. If a decision made it possible to modify the status of certain old addresses, the question could arise again for other wallets considered vulnerable or inactive.
However, we must keep the reading nuanced, the quantum threat remains a real challenge for the future of Bitcoin. A complete lack of response could expose some users to attacks capable of recovering funds protected by current cryptographic systems.
The difficulty therefore consists of protecting the network without transforming its operation into a system where an entity or a majority could decide the fate of existing assets. The solutions envisaged seek to respond to this threat while limiting changes to the protocol rules.
CZ admitted that he “ There was no perfect solution to this problem. “. The choice will therefore oppose two priorities: anticipating a future technological threat and preserving the historical principles which have allowed Bitcoin to function since its creation.
Going forward, the debate likely won't just be about Satoshi Nakamoto's bitcoin freeze, but a broader question: Can the network evolve in the face of a new technological threat without abandoning the principles that built its value? The answer will depend on the community's ability to strike a balance between protecting funds, resisting new attacks, and respecting the fundamental rules of Bitcoin.
