Bitcoin's Quantum Computing Vulnerability Threatens its Dominance
Bitcoin's cryptography can be theoretically cracked by a powerful quantum computer. This has sparked concerns about the future of the cryptocurrency.
The current implementation of Bitcoin's encryption is vulnerable to attacks from quantum computers, which could potentially steal funds directly from users' on-chain wallets. A proposal, BIP-361, aims to fortify the network against this risk but its final phase of activation won't kick in until 2027 and will take five years to complete.
Other cryptocurrencies, such as Zcash (ZEC) and Ethereum (ETH), are also vulnerable to quantum attacks. However, they have a head start on Bitcoin in terms of post-quantum cryptography implementation. Zcash is working towards becoming fully post-quantum operational within 12-18 months.
Under the right circumstances, Zcash could become worth more than Bitcoin by late 2031. This would require a quantum computing scare and insufficient preparation from Bitcoin's developers.
