※ Difference between Token & Coin
Coin: If one owns an independent blockchain network (Mainnet), it is called a coin.
Token: If one does not own an independent blockchain network, it is called a token.
Check out the video we uploaded on YouTube that displays the test screen of execution of a node, a wallet connection and inquiry, and termination of the node.
The test screen we see in this video consists of the YGGDRASH wallet (top left), the terminal of node execution (bottom left), and the browser of node inquiry (right). The wallet will be connected automatically once the node is executed, and the information of Network peer will also be updated. Moreover, by utilizing YEED coin* contract, the change of wallet balance can be checked after the YEED transfer.
Through continuous and diligent development work, we will present YGGDRASH that we have promised.
Thank you for your ongoing support and faith in YGGDRASH Project.
