To use everything Horizen’s network has to offer you will need to go to their website. Some features do not require you to sign up while others do. Without signing up you can see all the goods and service providers around the world which accept ZEN payments, learning on which exchanges you can buy these tokens and download one of the wallets the network has. All of this can be done by clicking on the “ZEN” tab on the main page. If you are one of the developers you will need to sign up using your GitHub account so you can earn “bounties” which are fees paid for developers who successfully tackle one of the tasks the network offers. The tasks can be changed daily based on the needs of the network and they might include doing some translating, writing an article on ZEN, creating a tutorial etc. Also, you can join the Horizen community for which you will need to register and can claim a small amount of free ZEN daily. Lastly, you can download the ZenChat through their website or the Sphere app which allows you to take control of your finances privately.
