Changpeng Zhao proposed freezing Satoshi's bitcoins: protection against quantum threat or risk to decentralization?
Binance founder Changpeng Zhao (CZ) has made a radical proposal that could change the rules of the game for the entire Bitcoin ecosystem. He is calling on the community to give Satoshi Nakamoto 12 months to move his Bitcoin before implementing a quantum-resistant network upgrade. If the coins are not moved within this timeframe, CZ suggests freezing them forever. This statement has certainly stirred up the crypto community and raises fundamental questions about the future security of the first cryptocurrency.
Quantum Threat: Why Is This Important Now?
According to Zhao, inaction on this issue is extremely dangerous. He warns that once quantum computing reaches a certain level, coins from old, vulnerable wallets will effectively go to whoever cracks them first. This refers to wallets from the early days of Bitcoin that use the Pay-To-Public-Key (P2PK) format. This format fully exposes the public key, making it vulnerable to attacks using quantum algorithms, such as Shor's algorithm.
CZ's idea is to protect these digital assets before they become easy prey for attackers. The one-year window, in his view, would give owners of inactive coins the opportunity to transfer them to a secure format, such as Pay-To-Script-Hash (P2SH) or SegWit addresses, which offer a higher level of security.
Not the First Such Idea
It is worth noting that Changpeng Zhao is not a pioneer in this area. Previously, a similar proposal was put forward by Ava Labs CEO Emin Gün Sirer. He also pointed out that quantum computing poses a direct threat to legacy technologies like P2PK. Sirer emphasized that modern wallets and systems, including Avalanche, do not use this vulnerable format, but in the early days of Bitcoin, it was the standard.
Sirer also noted that a quantum attacker only has a small window of opportunity for an attack, which complicates their task. However, in his opinion, when quantum computing becomes a real threat, the community should consider freezing Satoshi's coins or setting a deadline for transferring all coins to the P2PK format.
My analysis: The idea of CZ and Sirer is undoubtedly driven by a good intention—to protect assets. However, freezing Satoshi's Bitcoin, even if they are inactive, creates a dangerous precedent. It undermines one of Bitcoin's key principles—immutability and the inalienability of property rights. If we agree to freeze one person's assets, even if it is the creator, we open the door to censorship and control over the network in the future. Perhaps a more correct path would be not forced freezing, but the development and implementation of quantum-resistant signature algorithms that would allow owners of old wallets to voluntarily update their addresses. The community should focus on creating incentives for migration, rather than coercive measures. Otherwise, we risk ending up with a network that is less decentralized and more vulnerable to "top-down" decisions.
