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.

Mining a block is difficult because the SHA 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 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, blocks to a value such that the previous 2, 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.

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 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.

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. Early Bitcoin client versions allowed users to use their CPUs to mine. The option was therefore removed from the core Bitcoin client's user interface.

A variety of popular mining rigs have been documented. FPGAs typically consume very small amounts of power with relatively high hash ratings, making them more viable and efficient than GPU 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 For the amount of power they consume, they are vastly faster than all previous technologies and already have made GPU mining financially. Mining contractors provide mining services with performance specified by contract, often referred to as a "Mining Contract.

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. Bitcoin's public ledger the "block chain" was started on January 3rd, at 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 is a concept in the Delegated proof of stake coins, closely resembling pooled mining of proof of work coins. The network periodically selects a pre-defined number of top staking pools usually between 20 and , 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. Jump to: navigation , search. Categories : Mining Vocabulary.

Bitcoin Mining Hardware Comparison

An application-specific integrated circuit abbreviated as ASIC is an integrated circuit IC customized for a particular use, rather than intended for general-purpose use. Because they can only be used for one application, ASICs are expensive to design and produce. Though significantly more expensive to purchase, they are far more powerful higher hash rate and electricity-efficient than CPUs and GPUs graphics cards — used for mining in the early days of bitcoin — and even FPGAs field programmable gate arrays , which were, in , the most efficient option. Mining is now so competitive, and the difficulty rate so high, that attempting to do so without an ASIC is unprofitable. Many of these companies lease part of their mining power as a service. Cloud mining, or mining as a service MaaS , is an alternative that allows individuals to mine bitcoins without handling their own hardware. The hardware consumes high amounts of electricity, necessitates a powerful ventilation system, and is in itself expensive. As the writers at Coindesk put it, "cloud mining means using generally shared processing power run from remote data centres. One only needs a home computer for communications, optional local bitcoin wallets and so on" [8].

Current Generation Hardware

ASIC are rapidly replacing the traditional way of mining. Read more about Bitcoin mining is a booming industrybut the Bitcoin price increasing can help make up some of these losses. See Proof of work for more information. In order to generate a new hash each round, a nonce is incremented. Ssic more expensive and powerful products, such as the WhatsMiner M20, launched by ex-Bitmain chip design director Zuoxing Yang, are seeing an increasing level of buying. Dhat Basics.
