Bitcoin’s leading researcher presents an innovative solution that is causing discussions about the preparation process for quantum computing. He proposes a way to create quantum-resistant Bitcoin transactions without changing the basic blockchain framework.
Bitcoin could face severe threats in the future due to the emergence of quantum computers, which could break the cryptographic algorithms that currently protect transactions. In response to this threat, Avihu Levy, StarkWare’s Chief Product Officer, has introduced a novel scheme known as Quantum Safe Bitcoin (QSB).

Bitcoin QSB Innovation Faces Cost Challenges
In Levy’s proposal, he explains that QSB is able to safeguard Bitcoin transactions even from sophisticated quantum computers that run the Shor algorithm, an algorithm known to be effective in breaking cryptography.
What makes this method unique is the fact that there is no need for any soft forks or modifications to the Bitcoin protocol. The whole thing takes place within the existing system but just uses a new type of cryptographic puzzle.
Rather than relying on conventional elliptic curve signatures that can be broken using quantum computing, the QSB technique relies on a hash-to-signature technique. The user creates a hash that will randomly match the structure of the correct signature.
Nevertheless, there are certain disadvantages associated with the proposed idea. Levy stated that the transaction costs of QSB ranged from $75 to $150 in terms of GPU computations. It was not feasible for daily transactions.
Rather, the approach may only be appropriate for higher-valued transfers in which added security is worth the expense and difficulty.
Reactions From the Community
The reaction to the proposal has been overwhelming. For one, Eli Ben-Sasson saw the proposal as an important move that would instantly protect Bitcoin from being quantum-proof.
However, some people disagree. Daniel Batten came up with an objection against the proposal, saying that the proposal would not address critical issues.
One of the biggest concerns is 1.7 million BTC in addresses of older format. This amount might be compromised once the computers become sophisticated enough, making everyone wonder whether these coins need to remain where they are or need to be destroyed somehow.
Bitcoin Scaling Issues Raise Upgrade Urgency
Even the researchers who developed QSB agree that their solution isn’t a full one. Scaling is difficult, the Lightning Network doesn’t work on it, and it has unstandardized transactions.
This is why many people feel that upgrading the protocol behind Bitcoin will be the best way forward in the long run.
Some recent studies have made things more serious. According to a study by Google, hacking into the encryption of Bitcoin using quantum computers might take less effort than initially thought.
Meanwhile, Olaoluwa Osuntokun has proposed his own unique “escape hatch” approach. This solution gives individuals the ability to verify the control of their wallets without the risk of revealing any private information using the initial seed phrase.
Although Quantum Safe Bitcoin might be considered an interesting loophole, it is believed that this solution will last only for some time. In view of the fact that the technologies keep evolving, there is more and more necessity to discuss a certain future-proof solution that will ensure security for many years ahead.
