BlockBeats News, January 15th. According to Yonhap News Agency, the South Korean National Assembly today passed amendments to the Capital Market Act and the Act on the Electronic Registration of Stocks and Bonds to institutionalize Security Token Offerings (STOs). The amendments introduce the issuer custody account system, allowing issuers meeting certain conditions to directly issue security tokens using blockchain technology. This will enhance the security and utility of securities through blockchain technology and provide a legal basis for the issuance and circulation of new types of digital securities.
