The bitcoin digital currency could be hijacked by “selfish miners” causing honest users to lose time, effort and money. Due to the way the anonymous, decentralised, peer-to-peer digital currency is produced through complex computational processes, a rogue group of “selfish miners” could hijack the currency and overwrite the shared record of transactions.
