The post Quantum Computing and Bitcoin: Should We Worry Yet? appeared on BitcoinEthereumNews.com.

Quantum computers remain decades away from threatening Bitcoin’s robust security protocols. Bitcoin’s decentralized design ensures it can adapt to future quantum computing challenges. Quantum computing has raised concerns in the cryptocurrency community, notably accusations that this upcoming technology could jeopardize Bitcoin’s security. But based on the Crypto Tips video “Will Quantum Computing Kill Bitcoin?” these worries are mostly unwarranted and early. Although quantum computing presents theoretical risks, Bitcoin is nevertheless suited to handle these difficulties both today and in the next few years. Bitcoin’s Security Tools vs. Emerging Quantum Computing  According to the video, two fundamental tools—SHA-256 and the elliptic curve digital signature technique (ECDSA)—formulate the security of Bitcoin. These systems guard private keys and guarantee the blockchain integrity for Bitcoin. While SHA-256 serves as a cryptographic lock protecting Bitcoin’s data and driving the mining process, ECDSA guarantees that only the legitimate owner may access and spend Bitcoin. A sufficiently strong quantum computer might theoretically breach these systems by guessing private keys or evading SHA-256 security. The reality, nevertheless, is distant from this imagined world. Still in its infancy is quantum computer technology. A quantum computer would have to reach an extreme degree of power—about 133 million qubits to compromise Bitcoin’s cryptographic defenses—to pose a genuine threat to the currency. At just over 100 qubits right now, Google’s Sycamore is the most sophisticated quantum computer. This great difference emphasizes how far the technology has to develop before it poses a real concern. Even with fast developments, experts like scientist Sabine Hossenfelder project that we are at least decades away from quantum computers reaching such capability. Adapting Security Systems to Future Challenges  Furthermore, included in Bitcoin’s architecture are strong levels of defense against possible quantum risks. Public keys, which could hypothetically be sought for by quantum computers, are only revealed when…
