Lin Xinchuan, Chief Strategy Officer and Managing Director of DBS Bank, said that DBS Bank's parent company has been actively exploring the application of blockchain technology. The successful experience is of great reference significance for DBS Bank to promote the combination of blockchain and finance in China, especially in Shanghai. As an important trading port city, Shanghai has great potential in blockchain applications. Projects that succeed in Singapore will definitely achieve greater success in Shanghai. Lin Xinchuan emphasized that the biggest challenge in the application of blockchain is not the technology itself, but the establishment of an ecological system. Without enough participants, the network effect inherent in blockchain technology cannot be realized.
