  SHA-256 stands for Secure Hash Algorithm 256-bit and it is a cryptographic hash function used in the creation and verification of digital signatures. In the world of cryptocurrency, SHA-256 is the algorithm used in the mining process. Miners use their computational power to solve complex mathematical problems, and SHA-256 is the algorithm that ensures the integrity and security of the blockchain. It plays a crucial role in preventing fraud and tampering with transaction data. Without SHA-256, cryptocurrencies like Bitcoin would not be secure or reliable.

  SHA-256 is a cryptographic hash function that is used in the creation and verification of digital signatures. It's like a digital lock that ensures the security and authenticity of transactions in the world of cryptocurrencies. When you make a transaction using a cryptocurrency like Bitcoin, the transaction data is run through the SHA-256 algorithm, which produces a unique hash value. This hash value is then added to the blockchain, creating a permanent and unchangeable record of the transaction. So, in simple terms, SHA-256 is the technology that keeps your digital money safe and secure.
