Distributed ledger technology – or blockchain – has the potential to put control of personal data back in the hands of the public, rather than centralised corporations, which are increasingly vulnerable to cyber attacks, according to Michael Mainelli , executive chairman of distributed ledger company the Harvard Business Review . Writing in Z/Yen Group , he cited the Estonian model of using blockchain to create ID-kaarts, a secure identity system that has proved popular with the population. Michael Mainelli said a decentralised identity database could also give people the right to sell to, or withdraw their personal information from third parties, as they saw fit.
