The post Is Bitcoin Safe From Quantum Computing? CoinShares Data Says Yes For Now appeared first on Coinpedia Fintech News
The quantum computing threat to Bitcoin has been a hot topic recently.
A fresh report from CoinShares finally puts real numbers behind the debate, and the actual risk is much smaller than the headlines suggest.
Can Quantum Computers Actually Break Bitcoin?
CoinShares confirms that quantum algorithms like Shor’s could, in theory, expose private keys from Bitcoin’s ECDSA signature system. But the computing power needed to pull that off does not exist yet and is not coming anytime soon.
Breaking Bitcoin’s secp256k1 curve within one day would need around 13 million physical qubits. For context, Google’s Willow chip currently operates on just 105.
Ledger CTO Charles Guillemet told CoinShares, “To break current asymmetric cryptography, one would need something in the order of millions of qubits. And as soon as you add one more qubit, it becomes
