Satoshi Nakamoto's million BTC may face quantum threats, developers propose a three-phase elimination of old Bitcoin Wallet Addresses.

The self-custody service provider Casa has proposed an unprecedented initiative to "gradually phase out" old Wallet Addresses that may be vulnerable to quantum computer attacks, and over a million BTC held by Satoshi Nakamoto ( could also be affected. The reason behind this proposal is that an increasing number of experts are warning that the computational power of quantum computers will break existing encryption algorithms within the next 10 years, leading to a massive influx of early BTC into the market, which could impact the global economy.

Quantum threats affect the BTC held by Satoshi Nakamoto, with unprecedented market impact.

In recent years, quantum computers have become a hot topic )Quantum Computer(, which can perform calculations using the superposition of 0 and 1, far exceeding the computational efficiency of traditional computers that rely on binary. However, experts warn that within the next decade, it may be used to reverse-engineer the private keys of BTC Wallets. If successful, the early wallets that have not been upgraded could be cracked instantly, leading to a large amount of "vintage BTC" being liquidated, causing turmoil in the global market.

According to Deloitte's latest research, approximately 25% of BTC is in a quantum vulnerable state, which includes over 1 million BTC held by Satoshi Nakamoto.

Casa proposes improvements to address quantum threats.

To respond to quantum threats, Casa's CTO Jameson Lopp, along with 5 other developers, officially proposed a Bitcoin Improvement Proposal ) on 7/14, BIP(, to address the potential crises posed by quantum computers.

Lopp previously stated in an interview that if the Bitcoin community cannot "reach a consensus," it will not be able to face the devastating impact of quantum computers.

Proposal three-stage approach

The proposal allows users to upgrade to a more secure "post-quantum" address type in a phased manner:

Phase One: In the future, transferring money to "quantum vulnerable" old addresses will no longer be allowed, encouraging everyone to adopt new, safer addresses.

Phase Two ) Within five years (: All BTC with "quantum vulnerabilities" will be frozen unless upgraded to a secure Address for use.

Phase three (optional): A new BIP may be established to assist in recovering the frozen BTC.

The proposal directly calls out to users: "If you don't upgrade, be prepared to lose your assets."

The proposal discusses the BIP 360 technical discussion, aiming to add "multi-post-quantum locks" to BTC.

This proposal also mentions the post-quantum encryption scheme "BIP 360" designed by quantum research engineer Hunter Beast, which introduces a new type of address that supports post-quantum encryption. The main points are as follows:

Integrate 3 post-quantum signature algorithms

Based on SegWit v3, a new address format is established.

Users need to unlock the "traditional + post-quantum encryption" multi-layer mechanism when spending Bitcoin.

Each new Address will be generated using a multi-hash method to avoid public exposure of information.

The purpose of this entire mechanism is:

"Allow users to transfer their coins to a more secure format in advance, so that when quantum computers emerge, they won't be caught off guard and emptied out."

However, Lopp also reminds that the data volume of the quantum signature scheme is quite large, which may once again spark controversy within the community regarding the transaction processing efficiency of BTC.

The community discussion is quite low, and we must prepare for the future.

Casa CTO Loop finally stated that the BIP will first be published to the Bitcoin Core GitHub, then discussed and modified, and only then could it potentially be implemented. This is a consensus-driven process that usually progresses very slowly. According to previous reports, quantum research engineer Hunter Beast has stated that the Bitcoin community's current level of attention to this issue is far below what it should be. He emphasized:

"Even if there is only a 0.1% chance that quantum computers will destroy Bitcoin )BTC( in the coming years, that is enough reason for us to prepare for it now."
