Implementing first Industry 4.0 Use Cases with IOTA DAG Tangle — Machine Tagging for Digital Twins
The combination of machines with blockchain and the IOTA protocol transforms these machines into economically independent devices . These can transact among each other and form the basis of a Machine Economy in the 4th Industrial Revolution.
In this post we'll talk about IOTA for tagging of physical machines in a digital twin architecture (proof-of-concept).
This use case combines some decentral technologies like IPFS, IPLD and BigchainDB for file storage & database layer with the DAG tangle as well. DAG mean - directed acyclic graph .
A digital twin is a digital representation of a physical, biological and/or digital object. The Digital Twin project “Twin of Things” seeks to give a story to every physical object.
The "digital twin" is a key concept for bringing industry - 4.0 - to life supporting a broad variety of Industry Domains like Energy, Consumer Goods, Mobility, Supply Chain, Health Care.
Digital Twins in Marketing
A physical object - with a digital twin - will change old fashioned loyality programmes marketing drastically . A retail store do not need the personal data any more but only need to know the object identity which enables a marketing function and send marketing & sales messages directly into the " digital twin ". A customer will get an alert whenever a message from a marketing functions arrives. It can decide too to disable the alert or take write access away for the third parties.
A digital twin can store, manipulate and transfer tokens.
Technical Implementation
To implement a decentral - digital twin solution - the object data need to be :
- stored in a decentral database, connected with analytics and
- gathered from a physical object or machine.
They are testing IOTA for tagging machines & providing a trusted an secure data tx layer for extracting data out of the machines into the "digital twin".
The IOTA integration with IoT devices provides authenticity& integrity of data gathered from sensors or sent to actuators of a device.
Via message injection through a malicious third party — the sensors receive their own cryptographic identity using methods like crypto chips or IOTA light nodes on sensor. The identities of sensors are registered in the DAG tangle.
CarPass: Vehicle Telematics Data in a Digital Twin
A practicable APP of a digital twin with IOTA is CarPass for vehicles telematics data. The CarPass solution captures telematics data (e.g. trips , maintenance data,etc) & stores them immutable in the digital twin for private passenger, fleet , commercial vehicles.
This amaizing digital twin enables a vehicle to tell its story : where it went, what it did or how it was treated.
innogy is piloting IOTA for ensuring this trust in telematics data coming out of a car/vehicle.
