Circle Ones is a decentralized open communication network powered by blockchain 4.0 technology base on Binance Smart Contract (BSC). It provides decentralized cloud communication services such as messaging, VoIP, video, streaming, VPN, CDN, IoT data sharing, storage and more. With the API and SDK provided by Circle Ones, developers can build communication applications - for instance, messaging apps like WhatsApp and WeChat, VoIP apps like Skype, VPN services like SkyVPN, and live-streaming apps, without developing their own communication stacks and deploying their own networks. Circle Ones can significantly lower development costs and network costs for developers. Furthermore, all the applications running on CircleOnes are interoperable, while apps such as WeChat, WhatsApp and Telegram, built on top of proprietary protocols, are completely isolated from each other. On this decentralized and distributed P2P overlay network, nodes mine CON tokens by providing communication services to the network instead of through proof of work (POW) mechanism that consumes large amounts of energy.
