actually eb already discussed the most about the topic of mining bitcoin this. but then so more intrigued again to repeat the discussion of this, because a lot of perception wrong about mining bitcoin. many people assume that all activities looking for bitcoin is mine bitcoin. as for bitcoin free via faucet, giveaway, main game gets bitcoin free, post can bitcoin, considered mine. hopefully this explanation can give meaning "mine bitcoin" true. in the discussion "full explanation of mine bitcoin" it will be discussed in full, and divided into 5 part: 1. role and function miners 2. hardware mine bitcoin 3. energy consumption and ecology mining bitcoin 4. understanding of mining pool 1. role and function miners (miner) mining bitcoin actually, it is a activities mine using specific device. process through solve a series of issues mathematical (puzzle) based on the level of difficulty certain. well activities this is called "mine" or the term cool is "bitcoin mining". so he said, that if a person's mine bitcoin, meaning that the person using the device mining. can use the CPU, GPU, FPGA, and ASIC. explanation about this device will be discussed in the next section. actors mining, called the term "miners", or language cool is "miner". well, sometimes, we also still leaves a question, what exactly is done by the miners bitcoin this? let's discuss. process mining bitcoin similar as well as with the mining precious metals like gold. it's just the difference, if bitcoin mining done digital to solve puzzles, and gold mining through the process of gold mining. be similar, because sometimes miners there is a feel loss, as can not and difficult to find a gold, and there is also a successful. However, the picture in fact is, there will be much trouble during the process of mining. so is the case with mining bitcoin. there is a row of difficulty and challenges. as for being a miners, then we have to connect to the network bitcoin. after connected, then we will be a "node". term this node explain all devices connected to the network bitcoin. ago anything done by the miners? when someone is connected to the network bitcoin using a device, then node will do a series of the task. tasks performed are: listen to the transaction all nodes that has been connected in the network bitcoin, must listen to all transactions that occur. followed by validating the transaction heard of it. with the examination of the signature of digital (digital signature). it related truth digital signature and output in include in the transaction it has to be really have not been spent (not issued in other transactions-ensure no double spending). keep blockchain and listen to a new block created. a miners, actually works to keep blockchain. related in handling all transactions that occur. miners also, will maintain blockchain that has been save all transactions. miners, could ask for all the history of the block to the other nodes that has been login before he enters the network. listen to block the new in broadcast in the network, and validate the block in thank. because in block there is a series of transactions, then every transaction in the block and even then should also be validated, and invalid. make candidate new block after we have a full copy chain block (blockchain), then we can start building blocks. to do so, with a group all transactions that we listen to the new block, which will be able to expand on the block that we know. However, we also should be able to ensure that all transactions in block it is invalid. looking for nonce to be a block a valid after we validate all transactions on the candidate block earlier, the next is looking for nonce in order to make the block be invalid. step here is the most difficult step faced by the miners. hope block received this is a difficulty two faced. so, if we found a new block, there is no guarantee that the block it can be a part of the consensus blockchain. miners need luck here. hope miners other receive proposed the block. so we can start mine on the block. so not on the block miners other. receive benefits if it turns out miners other receive block we as a block a valid, then this is the time to make miners smile satisfied once work weight. because if block we received, it will earn reward by 25 bitcoin (valid at this time). in addition, if some of the transaction in block was listed transaction costs, miners can also collect all the cost of the transaction. well, sixth it is to be done by the miners. so clear Yes, that mine it is not meant as in the search for bitcoin in faucet, giveaway or the other. However, mine here Yes that by using the tool particular, which in the process is working on the sixth it above.@alanazhary
