Ghash.io - Definition from the Hotspot Shield Encyclopedia

GHash is a mining pool that has been in operation on the Bitcoin market since 2013.

GHash allows its users to mine Bitcoins using specific mining hardware or cloud mining facilities. This mining pool is the largest of its kind in the world and has been responsible for mining over $200 million worth of Bitcoins in its first year of operation. Aside from its Bitcoin mining pools, GHash also offers other pools for mining Alt currencies, and mining Dogecoin, Darkcoin and Auroracoin. The pool formed a partnership with CEX.IO to form cloud mining services that users could take advantage of. Due to the large nature of the GHash user base, there have been fears that it could reach the 51% threshold for the production of Bitcoins which could have adverse effects in the market.
