Bitmain, MicroBT, Canaan Race for 3nm ASIC

Competition intensifies among Bitmain, MicroBT, and Canaan as they aim to develop 3nm chips for mining hardware. These next-gen devices, expected by late 2025, promise major energy efficiency improvements. Industry watchers say breakthroughs are vital for sustaining profitability amid soaring global hashrates.

Currently, most high-end units use 5nm processes. Shifting to narrower architectures lets hardware makers retain customers facing rising network difficulty. However, achieving 3nm demands huge R&D budgets and partnerships with semiconductor foundries.

CoinTrust forecasts that whichever player launches 3nm ASICs first could seize a dominant sales share. Yet timelines might slip due to chip shortages and limited fabrication capacity.
