B-Mule: A Blockchain based Secure Data Delivery Service

Trying to modernize rural areas of the globe should be considered an important achievement. Nowadays being able to have an internet connection can prove life-saving. Although technological progress made sure to make the latter accessible to almost anyone, there are places that are hard to reach. The B-Mule project aims to bring messaging services to rural areas that cannot or do not have access to the internet. A data mule that can provide useful and trustworthy services to people inhabiting those areas in order for them to be able to communicate with the outer world without having actual access to the net. The aim of this work is to display the feasibility of creating a data delivery service (MULE) with the aid of blockchain technology. In particular, the ideal goal would be to launch the service on the Ethereum network. The reason for using the aforementioned technology is that we try to take advantage of the fact that data on the blockchain is immutable and thus, creating a delivery service that is natively tamper-proof would have a positive outcome in how data is delivered around the world.
