Bitcoin computing power MHS
mining has been successful, a total of one equipment (CPU mining, 4-core bar), computing power: 12.75 khash / S (generally abbreviated as KH / s)
KH / S is very rare, so is MH / s; Now the more common are GH / s, th / s, pH / s. The conversion rate is about 1p = 1000t = 1000g = 1000m = 1000K
now the basic unit is GH / s, and several hundred g mining machines are very common
[bitcoin mining machine]
bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
the popular digital currencies in 2013 are bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world
in short, it is a redistribution of computing power driven by interests.
garzik, was fortunate to be the owner of the first commercial ASIC miner.
the most difficult mining problem was 0, and the computing power was about 2p at the beginning of 2013, and now it has reached 100p
The first half: on November 28, 2012, the 210000 block was excavated, and the block reward was halved for the first time, and the block reward was 25btc
the second half: on July 10, 2016, starting from the 420.000 block, the bitcoin reward of each block was halved to 12.5btc
the third half: on May 12, 2020, bitcoin reward will be halved to 6.25btc
the next half: on May 9, 2024, bitcoin reward will be halved to 3.125btc
when the object moves downward at a constant speed, the vertical direction is also subject to the balance force, so the sliding friction is 50N
when f is further reced, because the sliding friction is related to the pressure and the roughness of the contact surface, only the pressure is changed when the object slides down, so the friction is also reced when f is reced, and the object accelerates vertically downward. When f is 0, the friction is also reced to 0
