Una aproximación al uso de patrones de eventos para el modelado de contratos inteligentes

Abstract

In this work, it is proposed to develop a smart contract design model event patterns-based. The use of event patterns in smart contract modeling is an emerging trend. This systematized and agile process allows, through event patterns, to reuse the knowledge and experience of previous solutions described with business patterns for the same use cases. Smart contract is programming code that is automatically executed when certain predefined conditions are met. These contracts are created and stored on a Blockchain platform, allowing for automatic execution and verification by multiple nodes on the network. Mapping the scientific literature published to date, one finds works that propose the application of patterns to the modeling of smart contracts. The results show that the use of event patterns in smart contract modeling is an emerging trend. Event patterns are used to model interactions between smart contracts and their environment, helping to improve the efficiency, security, and flexibility of smart contracts. Among the most commonly used event patterns are time patterns, flow control patterns, and communication patterns. In addition, specific tools and languages have been developed for modeling smart contracts based on event patterns. In conclusion, it is suggested that the use of event patterns in smart contract modeling is a promising trend that can significantly improve the efficiency, security and flexibility of smart contracts in various applications.
