Canaan

Canaan Creative is the second-largest Bitcoin ASIC manufacturer and the original. The company shipped the first commercial Bitcoin ASIC — the Avalon — in 2013, predating Bitmain. Canaan listed on Nasdaq in 2019 (CAN) and remains the only public company in the ASIC mining space.The current Avalon line spans home miners (Avalon Q at 90 TH/s on a 220V single-phase circuit, Mini3 at 37.5 TH/s, Nano 3S at 6 TH/s for desktop deployment) through commercial flagships (A1566, A15XP, A16XP, A1628). Canaan’s hash density is competitive with Bitmain’s, generally lagging the absolute efficiency frontier by 1–2 J/TH. Where Canaan stands out: tighter QC, more conservative thermal margins (which matter in hot ambient deployments), and as a public company subject to regulatory disclosure — for buyers prioritizing supply-chain transparency over peak efficiency.Manufacturer warranty is 12 months on new units, longer than Bitmain’s standard 180 days. Firmware is closed but allows broader configuration than Bitmain’s, including more flexible mining-pool failover.
