To form a distributed timestamp server as a peer-to-peer network, bitcoin uses a proof-of-work system. This work is often called bitcoin mining. The signature is discovered rather than provided by knowledge. This process is energy intensive. Electricity can consume more than 90% of operating costs for miners. A data center in China, planned mostly for bitcoin mining, is expected to require up to 135 megawatts of power.
A backdoor like Antbleed, if utilized, would give an ASIC manufacturer the power to effectively silence miners who support a version of the Bitcoin protocol that it doesn’t agree with. For instance, Bitmain could have flipped a switch and shut down the entire facility in Ordos if the company found itself in disagreement with the other shareholders.
