The latest Bitcoin miner is the Proto Rig, a modular, upgradable ASIC miner designed for the SHA-256 algorithm (Bitcoin mining) released on August 13, 2025, by Block Corporation (founded by Jack Dorsey). It has a maximum hashrate of 819 TH/s, a power consumption of 12000 W, and an efficiency of approximately 14.65 J/TH. With its replaceable hash plate design, this mining machine is designed to reduce upgrade costs and extend its lifespan, marking a shift towards more sustainable Bitcoin mining hardware. In contrast, recent models from other mainstream manufacturers include: - Bitmain Antminer S21 XP Hydro: 473 TH/s, released in early 2025. - MicroBT Whatsminer M63S: 406 TH/s, released in 2025. - Bitmain Antminer S21 Pro: 234 TH/s, released in July 2025. Proto Rig's hashrate is currently the highest known to be, but actual deployment may require considerations of cost, power efficiency, and availability. The hashrate of the entire Bitcoin network has exceeded 900 EH/s, so a single mining machine needs to be used in combination with other equipment.
