Quantum computers could kill off traditional cryptocurrencies within a few years. Cryptocurrency transactions are impossible to hack with conventional computers, but they could soon be exposed to the processing power of quantum computers.<\/b><\/h3>\n

 <\/p>\n

Most cryptocurrencies, including bitcoin, are blockchain-based<\/b>, an encrypted data chain maintained by a network of tens of thousands of computers. All bitcoin mining, buying and selling operations have to be validated by 51% of the computers in this network.<\/span><\/p>\n

That is why it is such a secure system<\/b>: with conventional computers, no hacker has enough computing power to hack or replace 51% of the computers in a blockchain network. They would need “thousands of years”, Canudas explains.<\/span><\/p>\n

However, <\/span>this could change with the progression of quantum computers<\/b>, which have already reached “private hands”, according to this 11Onze agent. In 2019, for example, Sycamore was presented, a 54-qubit quantum computer capable of performing in 200 seconds a calculation for which the most powerful traditional computer of the moment would need 10,000 years. Eagle, a quantum computer with more computing power than all conventional computers combined, was also recently made public.<\/span><\/p>\n\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n\n
