Quantum technology: A threat or blessing to Bitcoin?
TLDR;
- Quantum technology or Quantum computing fuses computer science, mathematics, and physics to power a supercomputer that solves complex mathematical equations.
.
- Quantum technology is seen as both a threat and a blessing to Bitcoin
.
- The technology is yet to mature and have tangible effects on Bitcoin and cryptocurrencies
.
The arrival of quantum computing brought with it the promise of a computer that could crack even the hardest mathematical equations. While this promise should be celebrated as the world moves to a data-driven era, the crypto world isn�t all happy with the technology. While some think the technology will help hasten developments in the space, others opine that it can be used by malicious actors to crack security protocols and infiltrate blockchain protocols and cryptocurrency wallets. Here, we look at whether quantum technology is a threat or a blessing to Bitcoin.
What is quantum technology or quantum computing?
According to IBM, a leading technology company:
.
�Quantum computing is an emergent field of computer science and engineering that harnesses the unique qualities of quantum mechanics to solve problems beyond the ability of even the most powerful classical computers.�
.
Quantum computers handle tasks that conventional computers can�t or, even if they do, they take more time to complete them. These powerful computers can be used in two broad fields. One, they can be used to pick patterns in large amounts of data. Two, they can be used to predict the behaviour of physical systems depending on a set of instructions or data.
.
Quantum computers can be used in industries that deal with complex mathematical logics like chemistry, pharmaceuticals, and machine learning.
How is quantum technology a threat to Bitcoin?
Quantum technology threatens Bitcoin on one major front: private keys. A quantum computer handles tasks at astronomical speeds. As such, it can easily cycle through all possible outcomes to access a Bitcoin wallet.
.
It could also exploit weaknesses in the Elliptic Curve Digital Signature Algorithm (ECDSA) cryptography approach used by Bitcoin to secure BTC wallets. Developers creating Bitcoin-powered products are already making plans on how to make their products quantum-resistant.
.
While the power of quantum technology seems to pose a threat to the security of Bitcoin and crypto wallets, experts think that quantum computing has between five and 20 years before it can be seen as an actual threat in the crypto world.
How is quantum technology a blessing to Bitcoin?
Quantum technology isn�t all doom in the Bitcoin and cryptocurrency spaces. It also has its advantages. How, you may ask. Well, picture this. What happens when you lose the private key to your crypto wallet? What happens when you misplace your Ledger Nano X hardware crypto wallet? You guessed right: Losing your wallet means losing your digital wealth.
.
However, that can change with quantum technology. Quantum computers can sift through billions of wallet address variations to find your lost private key, thus helping you recover your virtual wealth.
.
According to analysts, more than 3.5 million Bitcoins are permanently lost due to errors such as forgotten passwords, misplaced computer hard drives, and lost hardware wallets.
.
Quantum computers may first attempt to recover private keys of early Bitcoin wallets using older versions of the pay-to-public-key (P2PK) format. This cryptographic format is considered to have some unfixable flaws. The flaws are unfixable because these formats are no longer used by Bitcoin wallets, and no one concentrates on providing upgrades.
.
Although quantum technology can help resurrect lost Bitcoins, the Bitcoin community is divided on whether it�s right to bring those coins back into active circulation. For some, bringing them to life would impact BTC�s scarcity since they�d increase the circulating volume. To others, resurrected coins should be distributed to all BTC holders to maintain the economic balance.
Is quantum technology a threat or a blessing to Bitcoin?
The short answer is that it depends on which lens you�re viewing quantum technology from. To some, the technology provides the right tools for crypto hackers to steal Bitcoin by compromising the security of BTC wallets. To others, the technology makes it possible to recover lost Bitcoin.
.
Whichever team you choose, one thing is clear: quantum computers are hundreds of times faster than the fastest conventional computer available today. As such, it�s bound to create winners and losers.
Conclusion
Quantum technology is both a threat and blessing to Bitcoin and the crypto world. However, we still have a decade or two before the technology is widely adopted. Before then, the crypto world will have found a way to harness only the best of quantum technology and create quantum-resistant crypto-powered products.
