GoGreenLight.

GoGreenLight was a Swedish company set up in 2016 to buy the business of KnCMiner, a Swedish bitcoin mining firm that had gone bankrupt that May. It was a sister company of Borderlight, an IT and telecoms firm in Uppsala. The receiver agreed the sale on 12 August 2016, and GoGreenLight said it would keep KnCMiner’s mining and data centres running. In February 2017 Borderlight’s Sten Oscarsson told CoinDesk that 25 people were restarting KnC’s machines.

mempool.space credits GoGreenLight with 333 blocks, from 13 September 2016 to 11 August 2017; in October 2016, its busiest month, it found about one block in 80. Every one of them paid its whole reward to the same address, in the block’s first transaction. That was the company’s own income from mining, separate from the transactions confirmed inside the block. It found no more blocks after 11 August 2017, and no announcement of why has been found.
