Blockchain is a foundational technology with revolutionary potential. Through its decentralized trust mechanism, it offers a brand-new solution to the fundamental problem of "how to achieve collaboration in an environment without trust." Although it is still in its early stages of development and faces many challenges, blockchain is driving innovative applications in multiple fields such as finance, supply chain, and government affairs. It is expected to build a more transparent, efficient, and secure Internet of Trust (Web3.0) in the future.
