Why does video card mining cost electricity

1.

Graphics card mining is a process of increasing the bitcoin money supply

the reason why the graphics card is used is that mining is actually a competition of performance and equipment. The mining machine is composed of graphics card array. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining

computers have professional mining chips, and most of them work by installing a large number of graphics cards, which consumes a lot of power. One of the ways to get bitcoin is to download mining software and then run specific algorithm to communicate with remote server to get corresponding bitcoin

extended data

bitcoin does not rely on the issuance of specific monetary institutions, and is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

the bitcoin system is composed of users (users control the wallet through the key), transactions (transactions will be broadcast to the whole bitcoin network) and miners (the blockchain is generated by competitive computing to reach a consensus at each node, and the blockchain is a distributed public authoritative account book, including all transactions in the bitcoin network)

bitcoin miners manage the bitcoin network by solving the problem of workload proof mechanism with certain workload - confirming transactions and preventing double payment. Because hash operation is irreversible, it is very difficult to find the random adjustment number of matching requirements, which requires a continuous trial and error process that can predict the total number of times

when a node finds the solution matching the requirements, it can broadcast its results to the whole network. Other nodes can receive the new data block and check whether it matches the rule. If other nodes find that they really meet the requirements (the operation target required by bitcoin) by calculating the hash value, then the data block is valid, and other nodes will accept the data block

2. HD5870 graphics card
built in 1600 stream processors

pay attention to the number of stream processors in mining

and this graphics card is very affordable now

3. It depends on the power consumption superposition of the specific graphics card. The power supply is not always full output, but according to the demand. Now the 1080 single card is 180W, with six 100% running, it is 1080W, plus the power consumption superposition of other hardware. But I've only heard that the demand for password cracking machines is so high. I can't see such machines.

4. Same as begging bitcoin, address:

5. Campus network multi-purpose IPv6 ecation network or LAN access, the upper layer without operator equipment filtering, few firewalls, almost all ports exposed in the WAN environment, easy to attack

6. The whole machine needs one degree of power in about two hours,
if the CPU consumes a lot of power, it will consume more power,
and the graphics card consumes a lot!
