'GHash.IO' is one of the largest Bitcoin mining pools, which entered the mining market in July 2013 and contributes to over 30% of the overall hashing power making it the #1 pool in the Bitcoin network. The company frequently adds new features and expands trading possibilities. In March 2014, GHash.IO introduced the new scrypt mining features and added a number of altcoins available for mining such as LTC, DOGE, FTR and AUR. In April 2014, the mining pool launched GHash.IO Multipool Pro, which gave users the possibility to mine the most profitable <br/>coins with the help of new settings such as the conversion and the switch settings. GHash.IO charges 0% pool fee and provides 24/7 technical support for its users.

==Connection with CEX.IO==
GHash.IO and [[CEX.IO]] have the same account credentials, and therefore the pool is considered to be the mining side of CEX.IO. The connection between these two platforms allows users to benefit from simultaneous trading and mining. Mining power (GHS) purchased at CEX.IO mine new Bitcoins at GHash.IO until GHS are sold by the owner.

==Hashrate==
Although the hash rate of GHash.IO differs, on average the company has about 7 PH/s of power.

==PPLNS==
GHash.IO uses PPLNS (“Pay per last N shares”), a reward scheme, according to which payment is given to shares in a window, starting with the last share submitted and going backwards up to some number N of shares. Shares older than the window are not paid.
Shares are hashes, smaller than the target for difficulty of 1 (Usually, pools use such difficulty as the target for share, but technically, any difficulty could be used). Every hash created has a 1 in 232 possibility of being a valid share. In order to get Bitcoins in a more distributed and predictable way, miners use pools. If this is the case, miners are awarded Bitcoins, according to their shares.

==Compensated Downtime==
The pool’s policy provides compensation for CEX.IO mining hardware. Individual miners are not compensated.

==Merged Mining==
GHash.IO embodies merged mining of such alternative cryptocurrencies, as NMC (Namecoin), IXC (IXCoin) and DVC (DevCoin). At the moment, users can exchange mined NMC for Bitcoins, Litecoins or reinvest them in more GHS. IXC and DVC stand only for withdrawal to other exchanges or respective wallets.

==Multi Pool Pro==
On April 8th, 2014 GHash.IO presented a new scrypt mining feature, GHash.IO Multi Pool Pro, which enables users to mine the most financially rewarding coins at any given moment and benefit from additional settings, such as the conversion and the switch settings. According to GHash.IO, “Pro” stands for ‘progressive’, ‘professional’ and ‘profitable’. The new features allow users to mine new crypto-currencies, as well as to convert them into Bitcoins or Litecoins, as well as to adjust the miner to withdraw from the current job when switching coins. The Multi Pool Pro functions on the basis of the proportional reward system — when a block is mined, the reward is proportionally divided among all workers according to the size of their share.

==Market share==
In the beginning of January 2014 GHash.IO was very close to reaching 51% of all hashing power creating a serious threat to the Bitcoin network. However, all necessary precautions have been taken to change the course of events in order to maintain stability of the Bitcoin community. In order to eliminate the threat GHash.IO temporarily stopped accepting new independent mining facilities to the Ghash.IO pool.

== CEX.IO ==

[http://ghash.in/signin/ CEX.IO] a Bitcoin commodity exchange and a platform for simultaneous GHS trading and Bitcoin mining.

==History ==

CEX.IO project development started in early 2013 and proceeded with launching the CEX.IO domain, acquiring assets of [[GHash.IO]] and, finally, registering a legal company CEX.IO LTD in November 2013. By this time, according to Blockchain.info, GHash.IO has become the biggest mining pool, reaching over 42% of the overall Bitcoin mining power, which embodied the 51% attack threat. However, CEX.IO made an official statement, assuring the Bitcoin community that it would “take all necessary precautions to prevent reaching 51% of all hashing power, in order to maintain stability of the Bitcoin network.”
In January 2014, CEX.IO user base exceeded 160,000 users.

==GHS Trading==

CEX.IO platform allows users to trade GHS.
GHS (gigahash per second) = 1 000 000 000 hashes per second. The speed of mining is measured in hashes per second — the smallest amount of work done by a miner.
While mining is more or less passive way of gaining bitcoins, trading GHS allows you to be involved in the world trading processes and enjoy the fruits of your own activity on the Bitcoin commodity exchange.
GHS price depends on the correlation between market supply and demand. After purchasing GHS at CEX.IO, users automatically start mining blocks of Bitcoins.
CEX.IO is the only Bitcoin commodity exchange where trading and mining can be done simultaneously: even when you decide to sell your GHS, they will still be mining BTC until the moment they are sold. This means your GHS will be making profit for you till the last minute you own them.

==Cloud Mining==

Due to the shared credentials between CEX.IO and [[GHash.IO]] mining pool, users can trade GHS and mine Bitcoins simultaneously.
Cloud Mining is a concept of forming groups (pools), where their joint efforts are rewarded with greater income, compared to individual mining with personal hardware. In case of cloud mining, all Bitcoin mining is done in the cloud, and once a block is mined, users receive payouts according to their shares via PPLNS.
Apart from mining Bitcoins, users can simultaneously mine alternative cryptocurrencies, such as NMC, DVC and IXC.

With Bitcoin cloud mining users can forget about the most frequent mining problems, such as:
* Massive electricity consumption,
* Constant connectivity issues,
* The need to provide cooling and space
* Annoying noise
* Other hardware maintaining issues

==Trading Pairs==

At CEX.IO, users are able to trade:
*GHS/BTC
*LTC/BTC
*NMC/BTC
*GHS/NMC
*IXC/BTC

==Referral Program==

CEX.IO has a special [https://cex.io/ref Referral Program], according to which users can
bring new people to the platform and receive 3% of the referred ones’ GHS balance to their bonus account.

==Two-Factor Authentication ==

Users can secure their accounts with passwords, but CEX.IO strongly recommends using Two-Factor Authentication (2FA).

Users are free to choose from two 2FA applications — [http://en.wikipedia.org/wiki/Google_Authenticator Google Authenticator] or [http://authy.com/ Authy]. Alternatively, users can use simple cell phones and get a text or an audio message containing respective authorisation code.
