  SHA-256, which stands for Secure Hash Algorithm 256-bit, plays a crucial role in the world of cryptocurrencies. It is a cryptographic hash function that ensures the integrity and security of digital currencies. By using SHA-256, cryptocurrencies can achieve immutability, meaning that once a transaction is recorded on the blockchain, it cannot be altered or tampered with. This provides trust and transparency in the decentralized nature of cryptocurrencies.

  SHA-256 is like the secret sauce that makes cryptocurrencies secure. It's a fancy mathematical algorithm that takes an input (like a transaction) and produces a fixed-size output called a hash. This hash is unique to the input, so even a small change in the input will result in a completely different hash. This makes it virtually impossible for anyone to alter a transaction without being detected. So, SHA-256 is the backbone of security in the world of cryptocurrencies.
