How SHA-256 powers blockchain security and why it matters

What is SHA-256?

A secure hashing algorithm, commonly known as SHA-256, is a keyless cryptographic hash function that takes an input of variable length and produces a 256-bit hash output.

Using SHA-256 in Blockchain

SHA-256 is one of the most widely used hashing algorithms in blockchains such as Bitcoin, Bitcoin Cash, and Bitcoin SV. It plays a critical role at various stages of a blockchain, including:

Why is SHA-256 ideal for Blockchain ?

SHA-256 provides robust security and reliability. Here are some key characteristics that make it an excellent choice as the primary hash function for blockchain:

These properties make SHA-256 an ideal candidate for blockchains, offering unparalleled security and reliability.
