Quantum computers could theoretically be used to attack bitcoin although the crypto industry is preparing defenses. The machine has achieved a quantum volume score of 64 twice as powerful as rivals from ibm and google. Honeywell says that its newly launched quantum computer is the most powerful in the world.
Even if a quantum computer mined merely 2016 blocks in theory this would raise the difficulty so high that regular mining equipment would take an impossibly long time to create another 2016 blocks and reduce difficulty. Touching the bitcoin network would almost certainly be a touch of death. But there is one opportunity for quantum computing.
Fortunately satoshi nakamoto bitcoin s creator recognised the potential for technological advancements to impact bitcoin and a level of quantum resistance is already built in to bitcoin s encryption protocol. Naturally many people have wondered how potential advancements in technology like quantum computing could affect bitcoin. A quantum computer capable of cracking bitcoin s encryption could be just two years away.
The current generation of quantum computers max out at 54 qubits. A 4 000 qubit quantum computer could theoretically crack bitcoin s encryption in a matter of seconds. The fact that countless miners are powering the network means that bitcoin is decentralized no single user can control it.
Miners dedicate large amounts of computing power in order to solve cryptographic puzzles in exchange for block rewards. Bitcoin mining also relies on cryptography albeit in a different way. Bitcoin leverages three computationally intensive operations.
Mining by quantum computing hijacks the growth of the chain enabling a small number of nodes to hoard new bitcoin at the expense of miners using traditional mining hardware and also to control which blocks and transactions are added or blocked. From the point of view of someone who is building systems based on conventional cryptography quantum computing is a risk. On the modern cto podcast schwartz says quantum computing will break the cryptographic algorithms that keep cryptocurrencies like bitcoin btc and xrp as well as the internet at large secure.
By beating bitcoin at its own game.
Quantum computing bitcoin. Quantum computers are computers which exploit quantum mechanics to do certain computations far more quickly than traditional computers. A sufficiently large quantum computer would cause some trouble for bitcoin though it would certainly not be insurmountable. Quantum computers are exceptionally skilled at solving cryptographic calculations. To fully understand the threat that this poses to bitcoin and other cryptocurrencies we should first rehash public keys private keys and how bitcoin links the two together.
A quick bitcoin refresher every bitcoin wallet has a private key and a public key. Quantum computing is typically feared due to its potential to render bitcoin obsolete by cracking its cryptography. However one analyst alleges that there may be a much simpler way to do it.
