Nikolai Hampton argued in Computerworld that "There is certainly also no have to have for any '51 %' attack on A non-public blockchain, given that the private blockchain (more than likely) presently controls 100% of all block generation means. If you could assault or damage the blockchain creation applications on a private company server, you may properly Management 100% of their community and change transactions having said that you wished."[8] This includes a set of specifically profound adverse implications in the course of a fiscal crisis or debt disaster similar to the money disaster of 2007–08, wherever politically highly effective actors may well make selections that favor some groups within the price of Other folks,[fifty four] and "the bitcoin blockchain is safeguarded by the massive group mining effort and hard work.
