Introduction to Bitcoin Mining and Solo Mining
Bitcoin mining is the backbone of the Bitcoin network, ensuring that transactions are verified and securely added to the blockchain. This process relies on powerful computers known as Bitcoin miners, which solve complex mathematical problems to maintain the integrity of the system. Solo mining — running a miner independently against the entire network — represents the purest form of Bitcoin mining. It’s the digital equivalent of prospecting for gold: the odds of striking it rich on any given day are slim, but when you do find a block, the entire 3.125 BTC reward is yours. Both the Bitaxe Gamma and Bitaxe Hex line are designed for this exact purpose: solo mining from home, supporting the decentralization of the Bitcoin network while giving every pleb a shot at a full block reward.
