I want to correct you a little ... Confirmation Rewards will not only after the launch of MainNet, but after the launch of TestNet. TestNet is the same as MainNet. TestNet is a platform that will work in test mode and without some functions. When running TestNet, there may be some errors that will be corrected by the developers. In addition, in the process of TestNet, developers will continue to work on those features that are not worn out in TestNet. MainNet is a completely ready-made platform that will function as a clock (without errors and with all functions). Therefore, Confirmation Reward can be started immediately after TestNet starts, provided that you freeze units (1 unit = 10000 BOS) or run nodes (1 units = 40000 BOS).
DO YOU THINK THEY WILL SHARE THE COINS FOR THE TRANSACTION during testnet.
