When you hear about bitcoin “mining,” you envisage coins being dug out of the ground. But bitcoin isn’t physical, so why do we call it mining?
Similar to gold mining, bitcoins exist in the protocol’s design just as the gold exists underground, but they haven’t been brought out into the light yet, just as the gold hasn’t yet been dug up.
The bitcoin protocol stipulates that a maximum of 21 million bitcoins will exist at some point. What miners do is bring them out into the light, a few at a time. Once miners finish mining all these coins, there won’t be more coins rolling out unless the bitcoin protocol changes to allow for a larger supply. Miners get paid in transaction fees for creating blocks of validated transactions and including them in the blockchain.
To understand how bitcoin mining works, let’s backtrack a little bit and talk about nodes. A node is a powerful computer that runs the bitcoin software and fully validates transactions and blocks. Since the bitcoin network is decentralized these nodes are collectively responsible for confirming pending transactions.
Anyone can run a node—you just download the free bitcoin software. The drawback is that it consumes energy and storage space – the network at time of writing takes hundreds of gigabytes of data. Nodes spread bitcoin transactions around the network. One node will send information to a few nodes that it knows, who will relay the information to nodes that they know, etc. That way, the pending transaction ends up getting around the whole network pretty quickly.
Some nodes are mining nodes,usually referred to as miners. These chunk outstanding transactions into blocks and add them to the blockchain. How do they do this? By solving a complex mathematical puzzle that is part of the bitcoin program, and including the answer in the block.
The puzzle that needs solving is to find a number that, when combined with the data in the block and passed through a hash function (which converts input data of any size into output data of a fixed length, produces a result that is within a certain range.
For trivia lovers, this number is called a “nonce”, which is an abbreviation of “number used once.” In the blockchain, the nonce is an integer between 0 and 4,294,967,296.
How do they find this number? By guessing at random. The hash function makes it impossible to predict what the output will be. So, miners guess the mystery number and apply the hash function to the combination of that guessed number and the data in the block. The resulting hash starts with a certain number of zeroes. There’s no way of knowing which number will work, because two consecutive integers will give wildly varying results. What’s more, there may be several nonces that produce the desired result, or there may be none. In that case, the miners keep trying but with a different block configuration.
The difficulty of the calculation (the required number of zeros at the beginning of the hash string) is adjusted frequently, so that it takes on average about 10 minutes to process a block.
Why 10 minutes? That is the amount of time that the bitcoin developers think is necessary for a steady and diminishing flow of new coins until the maximum number of 21 million is reached (expected some time in 2140).
The first miner to get a resulting hash within the desired range announces its victory to the rest of the network. All the other miners immediately stop work on that block and start trying to figure out the mystery number for the next one. As a reward for its work, the victorious miner gets some new bitcoin.
At the time of writing, the reward is 6.25 bitcoins per block, which is worth around $56,000 in June 2020.
However, it’s not nearly as cushy a deal as it sounds. There are a lot of mining nodes competing for that reward, and the more computing power you have and the more guessing calculations you can perform, the luckier you are.
Also, the costs of being a mining node are considerable, not only because of the powerful hardware needed, but also because of the large amounts of electricity consumed by these processors.
And, the number of bitcoins awarded as a reward for solving the puzzle will decrease. It’s 6.25 now, but it halves every four years or so (the next one is expected in 2024). The value of bitcoin relative to cost of electricity and hardware could go up over the next few years to partially compensate for this reduction, but it’s not certain.
If you’ve made it this far, then congratulations! There is still so much more to explain about the system, but at least now you have an idea of the broad outline of the genius of the programming and the concept. For the first time we have a system that allows for convenient digital transfers in a decentralized, trust-free and tamper-proof way.

ethereum рост bitcoin otc algorithm ethereum bitcoin community abi ethereum bitcoin это Each full node enforces the consensus rules of the network, a critical element of which is the currency’s fixed supply. Each bitcoin block includes a pre-defined number of bitcoin to be issued and each bitcoin transaction must have originated from a previously valid block in order to be valid. Every 210,000 blocks, the bitcoin issued in each valid block is cut in half until the amount of bitcoin issued ultimately reaches zero in approximately 2140, creating an asymptotic, capped supply schedule. Because each node independently validates every transaction and each block, the network collectively enforces the fixed 21 million supply. If any node broadcasts an invalid transaction or block, the rest of the network would reject it and that node would fall out of consensus. Essentially, any node could attempt to create excess bitcoin, but every other node has an interest in ensuring the supply of bitcoin is consistent with the pre-defined fixed limit, otherwise the currency would be arbitrarily debased at the direct expense of the rest of the network.japan bitcoin bitcoin шахты bitcoin лучшие

bitcoin статья 'Once the virus has spread, there will be pressure to improve it, possibly by increasing its functionality closer to 90 percent, but users have already been conditioned to accept worse than the right thing. Therefore, the worse-is-better software first will gain acceptance, second will condition its users to expect less, and third will be improved to a point that is almost the right thing.'Monero enforces privacy by default. It uses different technologies that complement each other to achieve anonymity and fungibility. It aims to meet two criteria: untraceability (having multiple possible senders for a transaction) and unlinkability (being unable to prove that multiple transactions were sent to the same person). Untraceability protects the sender with ring signatures, while unlinkability protects the receiver with stealth addresses.1070 ethereum анонимность bitcoin bitcoin генератор bitcoin краны monero pro bank bitcoin математика bitcoin connect bitcoin ethereum miners bitcoin zebra bitcoin vizit accept bitcoin currency bitcoin bitcoin api bitcoin прогнозы ethereum install wikileaks bitcoin cryptocurrency wallet цены bitcoin bitcoin лохотрон отзывы ethereum инструмент bitcoin

A July 2018 warning emphasized that trading in any cryptocurrency is often speculative, and there is a risk of theft from hacking, and fraud. In May 2014 the U.S. Securities and Exchange Commission warned that investments involving bitcoin might have high rates of fraud, and that investors might be solicited on social media sites. An earlier 'Investor Alert' warned about the use of bitcoin in Ponzi schemes.ethereum contracts supernova ethereum
A related line of work studied the situation where the network is mostly reliable (messages are delivered with bounded delay), but where the definition of 'fault' was expanded to handle any deviation from the protocol. Such Byzantine faults include both naturally occurring faults as well as maliciously crafted behaviors. They were first studied in a paper also by Lamport, cowritten with Robert Shostak and Marshall Pease, as early as 1982.27 Much later, in 1999, a landmark paper by Miguel Castro and Barbara Liskov introduced practical Byzantine fault tolerance (PBFT), which accommodated both Byzantine faults and an unreliable network.8 Compared with linked time-stamping, the fault-tolerance literature is enormous and includes hundreds of variants and optimizations of Paxos, PBFT, and other seminal protocols.bitcoin авито bitcoin оборудование world bitcoin
