Quantum Computing Threatens Bitcoin Security
Researchers warn that a powerful enough quantum computer could crack Bitcoin's encryption, potentially allowing hackers to control the blockchain
The rapid advancements in quantum computing are raising serious concerns about the security of blockchain technologies like Bitcoin.
A study has precisely spelled out the risks posed by quantum computers to Bitcoin's encryption, with researchers arguing that a sufficiently powerful quantum computer could crack Bitcoin's SHA-256 encryption.
This could potentially allow hackers to seize control of the blockchain.
According to one expert, if a large quantum computer were available now, it would be possible to take over all the Bitcoin and access everybody's email and computer accounts.
The threat is not considered imminent, as it would require millions of qubits, far beyond current technology.
However, preparing for the 'quantum future' remains vital, with experts emphasizing the need for proactive measures to protect cryptocurrencies and cybersecurity systems at large.
Updating Bitcoin's encryption would be a massive undertaking due to its decentralized nature, potentially leading to significant downtime and losses.
