Mining
Introduction
Mining is the process of adding transaction records to Bitcoin's public ledger of past transactions (and a "mining rig" is a colloquial metaphor for a single computer system that performs the necessary computations for "mining". This ledger of past transactions is called the block chain as it is a chain of blocks. The blockchain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the blockchain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
Mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function.
The primary purpose of mining is to set the history of transactions in a way that is computationally impractical to modify by any one entity. By downloading and verifying the blockchain, bitcoin nodes are able to reach consensus about the ordering of events in bitcoin.
Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a "subsidy" of newly created coins. This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system.
Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new units available to anybody who wishes to take part. An important difference is that the supply does not depend on the amount of mining. In general changing total miner hashpower does not change how many bitcoins are created over the long term.
Difficulty
The Computationally-Difficult Problem
Mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network. This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros. The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a nonce is incremented. See Proof of work for more information.
The Difficulty Metric
The difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be. The rate is recalculated every 2,016 blocks to a value such that the previous 2,016 blocks would have been generated in exactly one fortnight (two weeks) had everyone been mining at this difficulty. This is expected yield, on average, one block every ten minutes.
As more miners join, the rate of block creation increases. As the rate of block generation increases, the difficulty rises to compensate, which has a balancing of effect due to reducing the rate of block-creation. Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by the other participants in the network.
Reward
When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network. Currently this bounty is 6.25 bitcoins; this value will halve every 210,000 blocks. See Controlled Currency Supply.
Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.
The mining ecosystem
Hardware
Users have used various types of hardware over time to mine blocks. Hardware specifications and performance statistics are detailed on the Mining Hardware Comparison page.
CPU Mining
Early Bitcoin client versions allowed users to use their CPUs to mine. The advent of GPU mining made CPU mining financially unwise as the hashrate of the network grew to such a degree that the amount of bitcoins produced by CPU mining became lower than the cost of power to operate a CPU. The option was therefore removed from the core Bitcoin client's user interface.
GPU Mining
GPU Mining is drastically faster and more efficient than CPU mining. See the main article: Why a GPU mines faster than a CPU. A variety of popular mining rigs have been documented.
FPGA Mining
FPGA mining is a very efficient and fast way to mine, comparable to GPU mining and drastically outperforming CPU mining. FPGAs typically consume very small amounts of power with relatively high hash ratings, making them more viable and efficient than GPU mining. See Mining Hardware Comparison for FPGA hardware specifications and statistics.
ASIC Mining
An application-specific integrated circuit, or ASIC, is a microchip designed and manufactured for a very specific purpose. ASICs designed for Bitcoin mining were first released in 2013. For the amount of power they consume, they are vastly faster than all previous technologies and already have made GPU mining financially.
Mining services (Cloud mining)
Mining contractors provide mining services with performance specified by contract, often referred to as a "Mining Contract." They may, for example, rent out a specific level of mining capacity for a set price at a specific duration.
Pools
As more and more miners competed for the limited supply of blocks, individuals found that they were working for months without finding a block and receiving any reward for their mining efforts. This made mining something of a gamble. To address the variance in their income miners started organizing themselves into pools so that they could share rewards more evenly. See Pooled mining and Comparison of mining pools.
History
Bitcoin's public ledger (the "block chain") was started on January 3rd, 2009 at 18:15 UTC presumably by Satoshi Nakamoto. The first block is known as the genesis block. The first transaction recorded in the first block was a single transaction paying the reward of 50 new bitcoins to its creator.
Staking
Staking is a concept in the Delegated proof of stake coins, closely resembling pooled mining of proof of work coins. According to the proof of share principle, instead of computing powers, the partaking users are pooling their stakes, certain amounts of money, blocked on their wallets and delegated to the pool’s staking balance.
The network periodically selects a pre-defined number of top staking pools (usually between 20 and 100), based on their staking balances, and allows them to validate transactions in order to get a reward. The rewards are then shared with the delegators, according to their stakes with the pool.
Although staking doesn’t require lots of computing power as mining, it still needs very stable and fast Internet connection in order to collect, verify and sign all transactions in the queue within a small timespan, which can be as short as one second. If a pool fails to do so, it doesn’t get the reward, and it may be shared with the next pool in order.
A lot of altcoins are using staking. Staking is often marketed as a much more efficient alternative. Unfortunately staking has the potential to not be much different than politics. A good example is that it's easy for a big actor to take over the network by simply buying enough coins. This actually happened in 2020 when TRON's Justin Sun took over the Steem "forum" network and then did some things that made some people unhappy.

There’s lots of retail activity, institutions aren’t leading the way, and relatively few people with big money ever sit down and try to really understand the nuances of the protocol or what makes one cryptocurrency different than another cryptocurrency. Each time Bitcoin reaches a new order of magnitude for market capitalization, though, it captures another set of eyes due to increased liquidity and price history.Bitcoin Priced in Goldbitcoin crypto перспективы bitcoin ethereum виталий konverter bitcoin bitcoin софт партнерка bitcoin bitcoin registration

Groups of information called blocks are added to the database one by one and form a very long list. So, a blockchain is a linear chain of blocks! Once information is added to the blockchain, it can’t be deleted or changed. It stays on the blockchain forever and everyone can see it.Cryptocurrencies use a technology called blockchain, which is essentially a database that contains a record of all of the transactions that have taken place on it. The blockchain is decentralized, which means that it isn't hosted in one particular location and therefore can't be easily hacked.check bitcoin coinder bitcoin neo cryptocurrency bitcoin ukraine 6000 bitcoin депозит bitcoin

Instead, each node stores a fraction of this data and only verifies those transactions.
