This term refers to a group of miners who control more than 50% of the mining network. The miner group can prevent a transaction from being confirmed which causes the transaction to be delayed. They can also reverse completed transactions so that they will double-spend and prevent other miners from mining already valid blocks. Although this term is still a hypothesis, the losses incurred if 51% occur would be quite large.
