CloudHashing.

CloudHashing sold cloud mining: a customer paid for a share of the company’s mining machines’ computing power for a year, and received the bitcoin that share mined without owning or running a machine. Emmanuel Abiodun, a programmer at the bank HSBC in London, founded it in February 2013; its company, Technology IQ Ltd, was registered in London that month. Its first machines ran in a data centre in Kansas City from June 2013, and in October it moved about 100 to Iceland, where geothermal and hydroelectric power is cheap. By December 2013 it had 4,500 customers, The New York Times reported.

mempool.space credits CloudHashing with 1,824 blocks, from block 261,716 on 4 October 2013 to block 343,436 on 14 February 2015. Most came in the first half of 2014, when in some weeks it found more than 6% of all blocks. Each block’s first transaction paid the whole reward to one CloudHashing address, and the company shared the bitcoin among its customers each day. These are payments to its customers, separate from the transactions confirmed inside the block. In May 2014 CloudHashing merged with HighBitcoin, a Silicon Valley maker of mining hardware, to form PeerNova, with Abiodun as president, and went on selling mining contracts under its own name.

Its last block came on 14 February 2015. By then PeerNova had raised money to build blockchainBlockchainBitcoin's shared record of every payment since 2009, stored in blocks that each link to the one before — which is what makes it a chain. software for businesses. By September 2015 CloudHashing’s website said only that the service “has been discontinued”, and asked customers still waiting for their balances to email the company; it gave no reason. Technology IQ was dissolved in August 2017.
