Bitcoin Faces Greater Quantum Computing Risk Than Ethereum, Citi Warns

💡 Citi warns that Bitcoin faces a greater risk from quantum computing than Ethereum.

The rise of quantum computing poses a significant threat to the security of cryptocurrencies, with Bitcoin potentially facing a greater risk than Ethereum, according to a new report from Citi.

The report, which analyzed the potential impact of quantum computing on various cryptocurrencies, found that Bitcoin's reliance on the SHA-256 hashing algorithm makes it more vulnerable to quantum attacks than Ethereum, which uses the Ethash algorithm.

Quantum Computing Risk

Bitcoin's SHA-256 algorithm is widely used in the cryptocurrency space, but it is also more susceptible to quantum computing attacks, according to Citi. The report noted that a 51% attack on the Bitcoin network could be carried out using a quantum computer, which would allow an attacker to control the majority of the network's mining power.

Ethereum's Advantage

Ethereum, on the other hand, uses the Ethash algorithm, which is more resistant to quantum computing attacks. The report noted that Ethereum's use of a proof-of-work consensus mechanism, combined with its Ethash algorithm, makes it less vulnerable to quantum computing attacks.

Other Cryptocurrencies

Other cryptocurrencies, such as Litecoin and Dogecoin, also use the SHA-256 algorithm and are therefore more vulnerable to quantum computing attacks. Citi warned that these cryptocurrencies could be particularly susceptible to 51% attacks if they were to fall victim to a quantum computing attack.
