Where to begin bitcoin mining
The bitcoin network is a peer-to-peer payment network that operates on a cryptographic protocol. Users send and receive bitcoins , the units of currency, by broadcasting digitally signed messages to the network using bitcoin cryptocurrency wallet software. Transactions are recorded into a distributed, replicated public database known as the blockchain , with consensus achieved by a proof-of-work system called mining. Satoshi Nakamoto , the designer of bitcoin, claimed that design and coding of bitcoin began in

Iran’s government recognises cryptocurrency mining with caveat
Gold has miners because people want gold and it just so happens, unfortunately, that most gold is deep in the earth. Bitcoin has miners because people want bitcoins, but something here seems silly: how did a bunch of bitcoins, the tokens of a man made invention, end up locked up in circumstances demanding mining?
When gold is mined, nothing is achieved beyond the discovery of new gold. When bitcoins are mined, however, a valuable service is provided to the Bitcoin network: decentralized transaction recordation and validation.
Bitcoin relies on miners to record and validate transactions because of a particular problem inherent in any system of digital currency: double spending. Double spending is the high-tech incarnation of counterfeiting. In the physical world, probably. In the digital world, probably not. The cost of that activity, alongside moral scruples and the threat of arrest, keeps counterfeiting in check. To fix this, the inventors of Bitcoin designed a system of network interactions, a protocol, that checks each putative Bitcoin transfer against a public ledger called the blockchain.
Bitcoin miners connect to the Bitcoin network like telephone operators. Miners use their computers to listen for transaction requests across the entire network and assemble a list of valid transactions. Bitcoins are not sent and received like file attachments in an email.
There are no files at all, only assignments of bitcoins made to various public addresses. Each public address has a matching private key and only the holder of that key is capable of digitally signing a new transaction request. Additionally, the request must have inputs. Inputs are the previous transactions that the sender is using to fund the new transaction. If you previously received five bitcoins from Alice and four from Bob, you can list these inputs to fund a new transaction to Cynthia of up to nine bitcoins in value.
Miners check two things when they hear your request. First they check to make sure that your digital signature proves that you were actually the recipient of those inputs.
To perform this second check, miners peak at a public database of all valid past transactions, called the blockchain, to see if those inputs were already used in a transaction or if they are still available. Copies of this blockchain are stored on the computers of all Bitcoin users that connect to the network. If everything checks out, the miner will add the transaction to their personal list of all valid transactions over the last few minutes. Every few minutes, one miner will be selected to add their personal list, a block, to the official blockchain, thus keeping the public record up to date.
A different miner is empowered to write each block, roughly every 10 minutes, and only valid blocks will be accepted by the rest of the mining community. This signature is a computer generated product of three inputs, 1 the signature of the predecessor block, 2 a list of valid transactions since that predecessor, and 3 a particular random number, called a nonce.
To understand it all, we need a bit more information about digital signatures. At their simplest, hash functions are math equations that take any given input and create a seemingly random output that will always correspond to that particular input. If a hash function is well written, any change to the inputs will drastically change the output string, and different inputs would never output the same string. By that standard, SHA is very well written.
Because it is the unique product of those inputs, that signature can be used to prove that the transactions therein described happened in a given order: within the current block or some previous block. Try and change the order by making up phony past blocks and the signature will no longer match.
This allows the particular beneficiary of a transfer to prove that they were the first to receive the coins; any subsequent double spending of those coins is fraud.
How do we pick a winner at regular intervals to make them compete? The solution is to ask for a string that will be difficult to generate quickly, a specific sort of output string, one that starts with a certain number of zeros, like this:. That long line of zeros at the start of the hash is statistically improbable, like flipping a coin and getting heads thirteen times in a row. Nonetheless, there is a particular combination of inputs that will result in a hash output that starts with all those zeros.
The miners repeatedly hash their two known inputs the previous block signature and the list of new transactions , along with guesses at the random nonce. Eventually, one miner will happen upon a nonce that will give them a signature with the requested number of zeros at the start. Miners that use more powerful computers can make guesses faster, and, like buying more lottery tickets, these miners will be more likely to win the race to find a particular hash.
This is why miners can compete with each other by investing in more powerful computers. More tries at the hash equals more blocks written to the blockchain over time. To prevent blocks from being written too quickly or too slowly as more or less computing power is used by miners, the protocol is adjusted every two weeks to demand a longer, harder to guess, or shorter, easier to guess, string of zeros at the front of the hash. The target for those adjustments is generation of a new block every ten minutes.
Whenever a miner solves a block by writing a signature with enough zeros, they broadcast it and the other miners validate the solution and check to make sure that the transactions listed are all valid. That brings us, at last, to the question of why miners mine.
This answer is actually simple, miners mine because the writer of a new block in the blockchain has permission from the protocol to give herself a reward of brand new bitcoins, called a coinbase transaction.
That reward started at 50 bitcoins per block. Every four years the protocol is adjusted, reducing the reward by half. One day the reward will be very small, but miners can also be rewarded by collecting fees volunteered by users that request transactions.

Summer on Seneca Lake, the largest of the Finger Lakes in upstate New York, is usually a time of boating, fishing, swimming and wine tasting. But for many residents of this bucolic region, there's a new activity this season — protesting a gas-fired power plant that they say is polluting the air and heating the lake. They have increased the electrical power output at the gas-fired plant in the past year and a half and use much of the fossil-fuel energy not to keep the lights on in surrounding towns but for the energy-intensive "mining" of bitcoins. Bitcoin is a cryptocurrency — a digital form of money with no actual bills or coins. The computers earn small rewards of bitcoin by verifying transactions in the currency that occur on the internet around the world. The math required to verify the transactions and earn bitcoins gets more complex all the time and demands more and more computer power. An estimate from the University of Cambridge says global bitcoin miners use more energy in a year than Chile. When the energy comes from fossil fuels, the process can add significantly to carbon emissions. The Greenidge plant houses at least 8, computers and is looking to install more, meaning it will have to burn even more natural gas to produce more energy.

Is Bitcoin mining worth the cost?
An obstacle to large-scale bitcoin mining is finding enough cheap energy to run the huge, power-gobbling computer arrays that create and transact cryptocurrency. One mining operation in central New York came up with a novel solution that has alarmed environmentalists. It uses its own power plant. The megawatts dedicated to Bitcoin might be enough electricity to power more than 35, homes. Proponents call it a competitive way to mine increasingly popular cryptocurrencies, without putting a drain on the existing power grid. Environmentalists see the plant as a climate threat. They fear a wave of resurrected fossil-fuel plants pumping out greenhouse gasses more for private profit than public good. The former coal plant, in a touristy region known for its glacial lakes and riesling wines, was converted to natural gas by Greenidge and began producing electricity in

Why China’s kicking out the crypto minersRELATED VIDEO: What is Bitcoin Mining? (In Plain English)
Note that this is definitely not a guide for devotees who are planning to build custom rigs for mining. Bitcoin mining is dominated by inconceivably huge mining facilities. In particular, there are two coins I find of interest because they have broad support and can be mined with consumer hardware. In a different vein, the newly-released Chia coins rely on what they call plotting and farming, which are dominated by storage requirements. There are plenty of other coins that you can still mine, that on any given day might be a little more or a little less profitable, but these two are a good place to start. When I first wrote about mining BTC years ago, you needed to have a full node on the network, your own wallet, and probably establish yourself with a mining pool.

Jack Dorsey's Block to build an open bitcoin mining system
Bitcoin mining is difficult to do profitably but if you try then this Bitcoin miner is probably a good shot. Bitcoin mining is legal and is accomplished by running SHA double round hash verification processes in order to validate Bitcoin transactions and provide the requisite security for the public ledger of the Bitcoin network. The speed at which you mine Bitcoins is measured in hashes per second.
