Cyworld is being prepared for a return under Sigma Chain, which said it completed its acquisition of the platform late last month and plans to launch a beta service in October, followed by a full reopening in the first half of next year. The company wants to rebuild the once-dominant South Korean social network as a Web3 platform that lets users convert mini-homepage content into NFTs and could eventually link a won-backed stablecoin to Cyworld's virtual currency, Dotori, if such an instrument is institutionalized in South Korea. Chief Executive Officer Kwak Jin-young said Sigma Chain is in talks with South Korean financial companies about adopting a stablecoin, but the company has no plans to issue its own token. Before the full launch, Sigma Chain said it will try to restore as much legacy data as possible, including about 17 billion photos and posts, and it plans to broaden revenue beyond advertising into fan communities and digital content under a 40-40-20 split for users, creators and the platform. The company also signaled overseas ambitions after stabilizing the domestic service, naming Southeast Asia, then Europe and the US, as possible phases. Legal risks remain after Kim Ho-kwang, former chief executive of Cyworld Z and head of Beta Labs, challenged the transaction and cited ongoing disputes over business rights and the domain, while Sigma Chain said its acquisition had no legal defects and that the domain dispute is unrelated to the company. The latest revival follows multiple failed attempts after Cyworld shut down in 2019, briefly returned under Cyworld Z in 2021 and closed again in 2023 because of funding difficulties.
