Abstract
Multi-agent systems can play a critical role in Islamic banking development by creating or reforming existing financial products that improve final output and solving a number of legal issues related to Islamic Sharia law. This paper introduces novel multi-agent protocols for a commodity-trading platform to be used for Islamic banking. This work focuses on the most popular (and debated) Islamic banking product, a personal financing product that involves commodity trading rather than direct lending. The protocols in question handle communication in a heterogeneous multi-agent platform to assist three types of actors: banks, retailers and individuals in need of cash.
