SendingNetwork, a Web3 communication network, announced that it will start node pre-sales in May. There are three types of nodes in the SendingNetwork communication network, and this pre-sale is for one of them, the WatchDog node, which is mainly responsible for verification work with Guardian nodes. A total of 60,000 units will be sold during this pre-sale, and 12% of SEND tokens will be allocated. SendingNetwork is building a decentralized communication network that aims to rebuild the TCP/IP model through blockchain technology, connect wallet addresses through decentralized routers, build point-to-point communication based on wallet addresses, reshape the Internet infrastructure, and achieve better security, privacy, and user control. SendingNetwork completed a $12.5 million seed round financing in February last year.
