Bitcoin mining technology has advanced significantly in 2025, with top rigs achieving a hashrate of 1.35 petahashes per second (PH/s). The MicroBT Whatsminer M79S spearheaded this development, while Bitmain and Block introduced hydro-cooled models to enhance efficiency. These innovations focus on improving cooling efficiency and reducing joules-per-terahash, setting a new standard for the industry as it moves towards even greater outputs in 2026.
