What is Google’s Willow quantum chip? Google’s Willow chip marks a new era in quantum performance, enabling complex computations with significant implications for various industries, including ...

Hashing is a one-way cryptographic function while encryption is designed to work both ways. Encryption algorithms take input and a secret key and generate a random looking output called a ciphertext.

An algorithm that transforms a given amount of data (the "message") into a fixed number of digits, known as the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental component in ...

I’m going to talk about the security behind Bitcoin addresses and keys, called Public Key Cryptography. This includes SHA256, Random Number Generators(RNGs), Hash Functions, and Elliptic Curve Digital ...

When Bitcoin launched in 2009, it was not merely a new online currency: it was a new model of finance. As a system of electronic money with no central government in charge but rather relying on ...

Quantum computing is on the horizon, promising to solve complex problems beyond the capabilities of classical computers. But for Bitcoin and other cryptocurrencies, which rely on today’s cryptographic ...

Proof-of-work (PoW), or Nakamoto consensus, is a decentralized consensus mechanism that secures a blockchain by requiring nodes to expend energy and compete against each other to solve complex ...

Amidst the chaos caused by a faulty software update from global cybersecurity firm CrowdStrike, Bitcoin remains unaffected due to its decentralized nature and independence from centralized providers ...

After nine years of research and competitions, the National Institute of Standards and Technology released the final version of its Secure Hash Algorithm-3 standard Wednesday. SHA-3 is a cryptographic ...
