Abstract

The advancement of blockchain technology and the Internet of Things (IoT) has presented us with unlimited possibilities to integrate the physical and the virtual worlds. In this work, we demonstrate how to override any existing public blockchain, that has enough redundancy in its transactions, to covertly broadcast arbitrary information. Besides, we implement and demonstrate our technique on a real-world cryptocurrency and show how it can be utilized in two specific applications: recording IoT data, and circumventing censorship.
