Ki Younger Ju, founding father of CryptoQuant, has proposed {that a} future Bitcoin (BTC) quantum improve could require freezing previous addresses to guard in opposition to potential theft by quantum computer systems.
He additionally believes that addressing the chance could be difficult as a result of the crypto neighborhood has traditionally struggled to agree on protocol adjustments.
Resolution to Quantum Threat
In a social media put up, Ju defined that anybody holding BTC in previous handle varieties faces the identical danger. It’s because the digital property might both be frozen by design or stolen if quantum machines evolve sufficient to interrupt BTC’s cryptography. He added that even securely saved non-public keys might turn out to be ineffective if homeowners fail to undertake protocol upgrades in time.
“In easy phrases, cash that seem completely protected at this time might turn out to be spendable by an attacker tomorrow,” warned Ju.
In response to the risk, the CryptoQuant founder has advised freezing previous addresses, together with the one containing Satoshi’s 1 million BTC, to forestall them from being stolen or compromised.
“Would you assist freezing dormant cash, together with Satoshi’s, to save lots of BTC from quantum assaults?” he requested.
Bitcoin’s safety depends on cryptography that’s successfully unbreakable by classical computer systems. Nonetheless, quantum computer systems change this assumption. Below sure circumstances, a sufficiently highly effective machine of this sort might get a non-public key from an uncovered public key.
As soon as a public secret is revealed on-chain, the chance is everlasting. Ju estimates that roughly 6.89 million BTC are presently uncovered to such assaults. Knowledge reveals that about 3.4 million BTC have been dormant for over a decade, together with Satoshi’s stash, representing tons of of billions of {dollars} in potential worth. He defined that with a lot worth in danger, hackers might be very motivated if the know-how turns into cheaper and simpler to make use of.
Social Consensus Challenges
Even when freezing dormant BTC is technically doable, reaching neighborhood settlement remains to be a serious problem. It’s because such options transfer shortly, whereas social consensus occurs slowly.
The Bitcoin ecosystem has traditionally struggled with agreeing on protocol adjustments. This may be seen within the block measurement debate, which lasted greater than three years and led to exhausting forks. One other instance is the failed SegWit2x improve, demonstrating how tough coming to an settlement might be.
Freezing cash, even to forestall quantum assaults, would seemingly face comparable resistance as a result of it conflicts with the OG cryptocurrency’s core philosophy of decentralization and consumer management.
Ju cautioned that the dearth of full settlement might probably result in rival BTC forks as quantum know-how progresses. Based on him, the true query will not be whether or not the risk will arrive in 5 or ten years, however whether or not the crypto neighborhood might be united on how one can deal with it earlier than then.
Elsewhere, Bankless co-founder David Hoffman believes that within the occasion of a quantum assault, ETH would proceed functioning usually even when BTC had been to fail as a result of it has been lengthy ready for these challenges.
