BCE is developed by the International Information Association team in collaboration with a blockchain technology development team from Silicon Valley. We are dedicated to exploring the integration of the blockchain world and the virtual information interaction world. Our goal is to create a virtual information interaction platform based on blockchain technology. This platform aims to address current issues within the information world such as centralized management, lack of transparency in transactions, data tamperability, and the absence of effective incentives. Leveraging the decentralized nature, immutability, transparency, distributed ledger, and digital assets inherent to blockchain technology, we aim to build a distributed blockchain-based virtual information interaction ecosystem for the information interaction world.
