Park Won-soon, the mayor of Seoul, has revealed a five-year plan to invest $108 million to develop the South Korean capital as a smart city powered by blockchain.

In a speech during his visit to Zurich, Park announced last week that his Blockchain Urban Plan for 2018–2022 will cover 14 public services in five areas, with a government budget totaling 123.3 billion Korean won (around $108 million), according to a CoinDesk Korea report on Thursday.

Park added that major public services that will adopt blockchain include labor welfare, vehicle history management, certification issuance, donation management and elections voting.

The mayor explained, for instance, the Seoul Metropolitan Government will use the technology to protect part-time workers who don't have labor contracts or are not covered by employment insurance.
