Mining Beyond Bitcoin: How SHA-256 Proof-of-Work Blockchains Compete for Hash Power
Introduction Bitcoin (BTC) remains the dominant Proof-of-Work (PoW) blockchain utilizing the SHA-256 hashing algorithm, but it is not the only one. Several other blockchains, such as Bitcoin Cash (BCH), Bitcoin SV (BSV), and other lesser-known SHA-256-based projects, compete for mining power. Since mining requires significant computational resources, miners tend to
