Cardano’s founder, Charles Hoskinson, has raised significant concerns about a recently proposed Bitcoin improvement, known as BIP-361, which aims to address vulnerabilities posed by quantum computing. According to Hoskinson, this proposal may not adequately protect all Bitcoin assets, particularly older coins that were held prior to 2013. His analysis suggests that approximately 1.7 million Bitcoins, valued at around $127 billion, could still be at risk of theft despite the measures put forth in BIP-361.
The proposal itself is designed to phase out older Bitcoin signature schemes over several years. It consists of three distinct phases: first, it would block new inflows to vulnerable addresses; next, it would freeze legacy coins; and finally, there would be an attempt to recover any assets that missed the migration deadline to quantum-resistant addresses. However, Hoskinson asserts that the recovery aspect is misleading, claiming it is not feasible for the 1.7 million coins in question.
Specifically, he noted that a significant portion of this at-risk Bitcoin is associated with Satoshi Nakamoto, the pseudonymous creator of Bitcoin, whose holdings are estimated to be worth up to $82 billion. Hoskinson pointed out that these assets originate from a timeframe when security measures were less sophisticated, thus making them more susceptible to future threats, particularly as advancements in quantum computing loom closer.
While he acknowledged some merit in the proposal, Hoskinson emphasized that it reflects a broader hesitation within the Bitcoin community to innovate. He highlighted the importance of on-chain governance as a way to tackle such issues more effectively and pointed to successful systems in other platforms like Cardano, Polkadot, and Tezos. “If you had on-chain governance, you could solve it,” he articulated, expressing frustration at the perceived reluctance of Bitcoin maximalists to embrace evolving ideas and solutions.
The urgency of addressing these vulnerabilities has gained attention as the conversation around “Q-Day” intensifies. This term refers to the time when quantum computers may possess the capabilities to break the cryptographic protections of Bitcoin. In a recent announcement, Google indicated that by 2029, it plans to transition its systems to post-quantum cryptography, adding fuel to the discussions surrounding potential risks.
In summary, while the BIP-361 could help secure a significant portion of Bitcoin’s supply, it also reveals the deeper challenge of technological adaptation within the Bitcoin ecosystem, as voiced by figures like Hoskinson.
