Bitcoin Quantum Resistance Proposal BIP-360 - Is My Bitcoin Safe from Quantum Computers? After reading the article by the user 코같투, I thought you must have already seen BIP-360. However, there may be some who do not know what this is, so I will explain it briefly. 1️⃣ Why Quantum Computers are Dangerous to Bitcoin As of now, it is not possible to mass-produce quantum computers at room temperature that can threaten Bitcoin. Currently. However, there is no certainty that this will be the case in the future, so if quantum computers emerge, my Bitcoin could be at risk. How? Bitcoin adopts a method of exposing public keys on the blockchain due to the Taproot addresses introduced in 2021. Therefore, if quantum computers come out, wallets that have not moved for a long time could become particularly targeted. The reason is that long exposure increases the likelihood of "calculating" the seed based on the public key, allowing access to the wallet. 2️⃣ BIP-360 Increases Resistance to Quantum Computers. First of all, it is important to note that BIP-360 is still just a technical proposal, characteristic of a decentralized protocol. In other words, it has been merged and reviewed on GitHub, but it still has a long way to go before final adoption. Nevertheless, many voices suggest that BIP-360 could serve as an alternative that can resist quantum computers without significantly disturbing the existing Bitcoin ecosystem. 3️⃣ So What Does BIP-360 Do? Basically, as mentioned above, the Taproot address method exposes the public key on the blockchain, and if assets do not move for a long time, the possibility of calculating the seed based on the public key with a quantum computer increases. Therefore, it is a method called P2MR that adjusts so that the complete public key is no longer output. However, BIP-360 does not introduce a new encryption signature method. In other words, it does not solve the risk of short-term exposure that can occur in a short time in the mempool. 4️⃣ Problems Arising Here The technical limitation of BIP-360 lies in its scope of application. In other words, even if BIP-360 is introduced, it will not create new transactions for Bitcoin that we essentially consider "burned" from the Satoshi era, so those coins remain vulnerable to quantum attacks. Therefore, the community is divided on this issue, with some saying it should be "permanently burned" or "no, the cypherpunks should be left as is." In other words, if my Bitcoin has been stored in a hardware wallet for a long time, it means that I need to create a transaction again in the P2MR form to ensure safety. The "dead?" Bitcoins from the previous Satoshi era cannot be moved by anyone, so they will not be protected by BIP-360. 🔰 Personal Thoughts First of all, if quantum computers exist, Bitcoin is not safe. However, this is not limited to Bitcoin. The encryption standards used in traditional finance will also be exposed to serious hacking risks if quantum computers exist. Ultimately, the development of quantum computers will be observed very carefully not only in the crypto space but also in traditional finance. It is something to watch, but I believe that it is not a narrative that will have an impact right now in 2026.
