How Bitcoin Mining Works: Understanding the Fundamentals
The Role of Proof-of-Work in Bitcoin Mining
Bitcoin mining operates on a Proof-of-Work (PoW) mechanism, where miners use high-powered computing devices to solve cryptographic puzzles. This process ensures decentralization and prevents fraudulent transactions. Crypto mining involves verifying and adding new blocks to the Bitcoin blockchain, rewarding miners with BTC for their contributions.
Why ASIC Miners Are the Best Choice for Bitcoin Mining
Initially, Bitcoin mining could be performed using CPUs and GPUs. However, as mining difficulty increased, specialized hardware known as ASIC miners (Application-Specific Integrated Circuits) became the most effective solution. These machines are designed specifically for cryptocurrency mining, offering higher hash rates and better energy efficiency than traditional hardware.
