Public

Blockchain technology can be useful, especially in the public sector. A centralized system may be inappropriate to manage public data, as data for public interest must be shared safely and easily among different parties. The key characteristic of blockchain is decentralization. Blockchain allows users to share data without engaging third-party organizations or corporate authentications. Korean government departments are also using the blockchain to plan various projects such as electronic voting, data verification, electronic verification, and smart city.
