Blockchain's Fame Reaches the Execution of Personalized Touristic Itineraries

Abstract

Blockchain trends cover more and more tech domains making it one of the most used technologies in the last few years. This is due to two essential aspects. First, it is a distributed peer-to-peer network where there is no need for third part to execute operations between peers. Second, blockchain implements mechanisms to make the most data sensitive operations executed in a trusted way. Regarding these attractive aspects, we intend in this work to use the blockchain technology for the implementation of touristic itineraries. We consider the latter as process choreographies involving different participants. We intend to model and execute the touristic itineraries generated from a personalized trip planner called CART in raw XML format in a way that respects this collaborative aspect and resolves the problem of trust. We will propose a pattern and its transformation rules to reconstruct the itineraries presented in declarative annotations such as XML to smart contracts written in some smart contract-specific programming language called Solidity. Experimental results show promising perspectives of the deployment of the proposed solution to execute touristic plans.

Running Transactional Business Processes with Blockchain's Smart Contracts

“…In a more recent work [14], authors start from a declarative input (XML) and propose a set of transformation rules to convert touristic itineraries presented in XML to SC.…”

“…However, the proposed approaches [1], [14] as well as the existing tools like Caterpillar [9] handle only the workflow execution of business processes without taking into consideration the case of task failures and the subsequent behaviour of the business process in such cases. VI.…”
