I notice that last years a lot of new companies start appearing and offering ASIC miners for different algorithms. I started wondering how it's possible so many companies to came with products ready for the market in so short time.
It's not clear from most manufacturers webpages if they are using there own developed ASIC chips or rebranded from some main patent holder.
I would like to know if anyone has any information on mining equipment companies who have developed their own chips, or are buying them from somewhere in order to make a list that might give more light in the tunnel.
Companies with own chip development:
- Bitmain - EtHash, SHA256, Scrypt, X11, EquiHash
- Canaan (Avalon Made) - SHA256
