Homepage > News > Business > Block’s Proto Mining System: Making BTC mining efficient Bitmain has held control of most of the ASIC market since roughly 2015. Jack Dorsey, however, seems to be making a run for it. In August 2025, Block Inc., led by Dorsey, launched its Proto Mining System. This new BTC mining hardware is designed to compete with Bitmain, which is believed to control about 80% of the ASIC market. The system includes the Proto Rig, a modular ASIC miner, and Proto Fleet, which is free open-source software for mining operation management. The aim is to boost output, lower expenses, and spread out mining activities. The Proto Rig is in use at Core Scientific’s (NASDAQ: CORZ) location in Dalton, Georgia, providing miners a way to handle increasing energy expenses and rapidly obsolete hardware. With the United States accounting for 44% of the world’s hash rate, Block’s system could reshape mining standards, address key industry problems, and build a more stable setup. Standard ASICs last about three to five years before they’re outdated, meaning miners must spend a lot to replace them. The Proto Rig’s design lets miners upgrade hashboards individually, which could extend the hardware’s life by about 10 years and cut upgrade costs by 15–20% each time. It can deliver 819 terahashes per second (TH/s) at 14.1 joules per terahash (J/TH), making it 1.5 times more power-dense than older systems and compatible with new and old data centers. Proto Fleet makes it easier to adjust power, keep an eye on hash rate, and provide maintenance, which helps smaller operators without the cost of proprietary software. The BTC block rewards were cut in half in April 2024 to 3.125 BTC, which put more pressure on miners’ profits, making efficiency very important. Electricity accounts for 70–80% of operating…
