These are chips that are developed by technology firms (some of which are miners) that can rapidly increase mining efficiency. (coinbureau.com)
Among other innovations, this new business will locate Looop's solar power generation facility on top of CMJ's mining container to increase thermal insulation, maximize power generation, and mining efficiency on a square meter basis. (cryptoninjas.net)
The second problem is mining hardware optimization called ASICBoost which allows for a greater mining efficiency in the electricity spent versus hashes per second produced. (bitfalls.com)
