Diff B/w Up Milling And Down Milling

Lathe vs Milling Machine: What's the Difference? - Monroe ...

Milling machines are taller than lathes, but they also have a shorter length, allowing manufacturing companies to place them in small spaces. Aside from shape and size, though, the primary difference between lathes and milling machines is their method of operation. With lathes, the workpiece rotates against a stationary cutting tool.

Everything you need to know about Bitcoin mining

Bitcoin uses the hashcash proof-of-work function. The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a "subsidy" of newly created coins.
