Building Cities Beyond Blockchain (BCB Blockchain) is the first blockchain protocol to serve smart city solutions and its goal is to achieve a more livable, workable, trust-free and sustainable city of the future. BCB will be committed to the development of its ecosystem, providing a one-stop shop for turning smart city concepts into smart city solutions. As the core infrastructure, the BCB token can not only support the operation of its ecosystem, it can also enable BCB holders to use dapps and smart contracts for the payments of products and services. With its low transaction cost, BCB can effectively improve transparency and settlement efficiency of transactions in cities. As more use cases of blockchain are applied for smart cities, there will be more forms of usage of BCB technology and BCB tokens.
