Which enterprises are included in the bridge between traditional economy and digitalization?

The bridge connecting the traditional economy and digitalization includes all industries related to blockchain. Blockchain is the only way to reduce the cost of mutual trust and mutual certification after the continuous expansion of human economic activities and scale. In an increasingly complex world in the future, when it is difficult to verify everyone's true identity, the blockchain completely solves the problem of how to prove that my mother is my mother. If there is no blockchain, the cost of trust in the contemporary world will be infinite. In addition, blockchain is a bridge connecting parallel real economy and digital economy. Without this bridge, there is no way to connect the two in parallel. Today, the world must be transformed into digital. Without blockchain, such a transformation cannot be completed.
