Blockchain provides the general public with a useful mechanism for reaching consensus. It combines the world’s leading technologies and theories, namely, theoretical computer science, mathematics, algorithms, cryptography, game theory, and economics. Blockchain brings to the world a promising decentralized internet, new ideas, and business opportunities. To protect the decentralized communities and keep them running, we need a highly secure and trustable system. Smart contracts generally remove the barrier of trust between users. 
They reduce the intermediary costs that may exist in the transaction process. With unsupervised, self-executing “contracts,” individuals can do business and collaborate without ever meeting or knowing each other. The design and concept of smart contracts apply to many different scenarios, such as e-commerce, insurance, home rental, banking, financial services, import and export, and many others. Smart contracts, however, have been neither widely accepted nor utilized due to several limitations: difficulties in contract preparation, inability to verify off-chain information, functional limitations, lack of on-chain governance and dispute resolution, and pseudonymity.
