TestNet is a public testing network open for connection that fully matches MainNet by technical characteristics and functions. This network is needed to test future solutions before they are implemented on the MainNet network.
The working consensus algorithm, electronic digital signature, Blake2 hash-coding algorithm, proprietary UDP-based data transfer protocol — all will be opened to our community users. Inside the system, the exchange will be enabled by the test currency unrelated to real money. The test network also has coins that can be received in advance through Support. You can download a TestNet for Windows x64 and Linux x64 on this page
