World Wi-Fi is a decentralized network which will connect required participants for providing free Wi-Fi services. These participants will be router owners, advertisers and regular users. World Wi-Fi plans to collaborate with advertisers and to give them possibility to promote their products via specific firmware developed for all types of existing Wi-Fi routers. Consequently, router owners will be able to install this firmware and to host advertising campaigns, receiving rewards in form of WT tokens. Finally, ordinary users will benefit from this system and will have access to free Wi-Fi by watching targeted advertisements on their devices.
