Top Slovenian University Unveils Blockchain-Powered Christmas Tree
Blockchain developers at the University of Ljubljana, the largest and oldest university in Slovenia, have created a distributed ledger technology (DLT) powered Christmas tree that allows anyone to control the color of its lights by sending Ethereum donations, reports Decrypt on December 19, 2019.
Xmas Trees on the Ethereum Blockchain
In a first, students of the University of Ljubljana’s Faculty of Electrical Engineering have demonstrated once again that there are quite numerous use cases for the revolutionary distributed ledger technology (DLT).
Per sources close to the matter the team of engineers has integrated blockchain technology and the internet of things (IoT) into a regular Christmas light, transforming it into an interactive and exciting one that allows anyone to change the color of its lights by sending payments to it.
Commenting on the innovative creation, MatevZ PustiSek, the project leader noted that the blockchain-powered Christmas light is just a working prototype for students of the faculty to experiment with.
“We created a simple web user interface that can be opened on your mobile phone or another device, then you can select the colour of the lights and duration of time it should go on for. In the background, it executes an Ethereum transaction which is accepted by a smart contract.”
The team says the smart contract is triggered by Swether, an IoT device dedicated to managing the lights. Swether constantly scans the network for payments and once it finds any, it changes the color of the lights accordingly.
While the Christmas tree is just a simple demonstration of how blockchain technology and IoT can be used to manipulate real-life objects, PustiSek firmly believes that students could apply the knowledge gained from it into developing more complex decentralized applications such as charging points for electric vehicles in the future.
The Nano Christmas Tree
Elsewhere, the Nano (NANO) team have joined forces with Pixel Bar, to create a Nano-powered Christmas light.
Just like PustiSek’s project, the Nano-powered Xmas lights change color when Nano payments are sent to it and the team says the funds will be donated to the Simon on the Street charity organization.
“We created this to show that you could have a fun and engaging way to drive donations for charity by having something cool and innovative tied to a simple donation,” declared one of the developers.
At press time, the price of Nano (NANO) sits at$0.68, with a market cap of $91.46 billion as seen on CoinMarketCap.
