The case for blockchain as a crimefighting, regulatory friendly choice for enterprises is getting stronger. Mayor Yang Yiwen of China’s Loudi city has cited the technology’s crimefighting capabilities as a powerful “weapon” to be used against crime.

The mayor is implementing a trial blockchain project in his city, combining computing and big data to allow telecommunication operators, banks municipal departments and utilities to share data.

At a meeting of officials from the Municipal Public Security Bureau, Yang Yiwen specifically promoted how this could be used to help fight crime and collection. Having impeccable data shared across these different organizations would allow for more accurate, deeper investigations, he said.

Chinese governments have increasingly turned to blockchain technology for all sorts of uses. Shanghai has turned to the technology to help record court hearings, making them less vulnerable to corruption. China’s been so impressed with the results of blockchain evidence that they’ve moved to make it legally binding evidence in the Supreme Court.
