IoT + Blockchain = <3
In this workshop, we got to tangibly experience (literally) blockchain in our hands. James Brown and James Sangalli were showcasing an application of the Blockchain using a small pocket sized device they have designed. The potential blockchain has for Internet of Things (IoT) is enormous: in cargo and logistics, retail, healthcare and many more practical areas.
James Brown presenting at the MCIC: The schematics a network connecting IoT devices.
They had brought with them tiny IoT devices that they had designed. Each device was connected to the Ethereum network through an Azure server which communicated with a local geth node. The devices had a small LED that displayed the current Ether (Ethereum Blockchain's currency) balance. Every time a button was pushed, a small amount of Ether would be sent through the Ethereum network into a joint pool. When the next Ethereum block was mined, the balance in the pool would be randomly given to one of the other devices.
Although simple, this was a powerful demonstration of the automation of transactions. This application could be modified such that the condition upon which the balance is distributed can vary, leading to many other applications for Blockchain in the IoT space.
James Sangalli presents at the MCIC the future of IoT blockchain network.
