University of Slovenia and Nano build blockchain Christmas tree, remotely use smart contract transactions to operate lights

According to Decrypt, the University of Slovenia and the Nano-funded team collaborated to build a blockchain Christmas tree. Through the operation of the blockchain interface, you can remotely control the light color and time of the Christmas tree. These operations will be performed in the background as Ethereum transactions accepted by the smart contract Swether device. This move is also considered a good starting point for students to develop decentralized applications.
