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.
*****U Mining
Early Bitcoin client versions allowed users to use their *****Us to mine. The advent of GPU mining made *****U mining financially unwise as the hashrate of the network grew to such a degree that the amount of bitcoins produced by *****U mining became lower than the cost of power to operate a *****U. The option was therefore removed from the core Bitcoin client's user interface.
GPU Mining
GPU Mining is drastically faster and more efficient than *****U mining. See the main article: Why a GPU mines faster than a *****U. 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 *****U 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.

One of the main problems cited about cryptocurrency is the fact that it's volatile; although many users and merchants may want the security and convenience of dealing with cryptographic assets, they may not wish to face that prospect of losing 23% of the value of their funds in a single day. Up until now, the most commonly proposed solution has been issuer-backed assets; the idea is that an issuer creates a sub-currency in which they have the right to issue and revoke units, and provide one unit of the currency to anyone who provides them (offline) with one unit of a specified underlying asset (eg. gold, USD). The issuer then promises to provide one unit of the underlying asset to anyone who sends back one unit of the crypto-asset. This mechanism allows any non-cryptographic asset to be 'uplifted' into a cryptographic asset, provided that the issuer can be trusted.pull bitcoin bitcoin cap

The Ethereum network is designed to produce a block every 12 seconds. Block times will vary based upon how long it takes miners to generate a hash that meets the required mining difficulty at that moment. 12 seconds was chosen as a time that is as fast as possible, but is at the same time substantially longer than network latency. A 2013 paper by Decker and Wattenhofer in Zurich measured Bitcoin network latency and determined that 12.6 seconds is the time it takes for a new block to propagate to 95% of nodes. The goal of the 12 second design is to allow the network to propagate blocks as fast as possible without causing miners to find a significant number of stale blocks.byzantium ethereum футболка bitcoin bitcoin википедия clicks bitcoin видеокарты ethereum bitcoin future bitcoin 99 bitcoin хардфорк monero майнеры bitcoin биржи комиссия bitcoin bitcoin ютуб токен bitcoin ethereum raiden bitcoin kaufen bitcoin форки euro bitcoin monero simplewallet автомат bitcoin source bitcoin Technical debt usually results from beginning a software project without having a clear conception of the problem being solved. As you add features, you misapprehend the actual goal of your intended users. As a result, you end up in an 'anti-pattern.' Anti-patterns are patterns of design and action which, despite looking like the right path at the moment, turn out to induce technical debt. Anti-patterns are project- and company-killers because they heap on technical debt.bitcoin legal отзывы ethereum зарабатывать ethereum

Concerns about bitcoin's environmental impact relate bitcoin's energy consumption to carbon emissions. The difficulty of translating the energy consumption into carbon emissions lies in the decentralized nature of bitcoin impeding the localization of miners to examine the electricity mix used.

These wallets can display and access the contents of the wallet although they don't technically contain any currency. Access to a lost wallet can usually be regained by entering a series of security words or numbers that were created during the setup process. If these codes are lost as well, then the access to the wallet and any funds associated with it will remain inaccessible.bitcoin кошелька bitcoin daily

The Ethereum protocol would not 'support' any of the applications directly, but the existence of a Turing-complete programming language means that arbitrary contracts can theoretically be created for any transaction type or application. What is more interesting about Ethereum, however, is that the Ethereum protocol moves far beyond just currency. Protocols around decentralized file storage, decentralized computation and decentralized prediction markets, among dozens of other such concepts, have the potential to substantially increase the efficiency of the computational industry, and provide a massive boost to other peer-to-peer protocols by adding for the first time an economic layer. Finally, there is also a substantial array of applications that have nothing to do with money at all.On 26 October 2013, a Hong Kong–based bitcoin trading platform owned by Global Bond Limited (GBL) vanished with 30 million yuan (US$5 million) from 500 investors.ethereum mist 600 bitcoin Ledger Wallet Deal Active Right Now:bitcoin проверить ethereum org bitcoin видео avto bitcoin халява bitcoin
