A study of application platform for smart contract visualization based blockchain

In recent years, blockchain, which is the base technology of the 4th industrial revolution, is rapidly emerging as an alternative to the centralized data management method. An application platform for providing blockchain networks and services to both the general public and the underprivileged (elderly people, farmers, people with disabilities) is essential. In particular, the socially vulnerable (defective families, grandparents, children, multicultural families, settlers, individuals living in basic conditions) need clear guidelines for complex and high-level contracts. Therefore, in this study, we designed a smart contract visualization application platform to improve user convenience. This system provides an easy-to-use interface for the socially vulnerable and underprivileged and presented guidelines for signing complex and high-level contracts. In addition, we designed a mobile UI/UX for smart contracts and enabled the automatic creation of Ricardian contracts.
