IOTA is a cryptocurrency designed for the Internet of Things (IoT). Unlike traditional blockchains, it uses a unique structure called the Tangle, which allows for faster transactions without the need for miners. This makes it more efficient for devices to communicate and transact with each other. The main goal of IOTA is to enable secure data and value transfer between connected devices. It aims to facilitate a machine-to-machine economy, where devices can autonomously share information and perform transactions, enhancing automation and efficiency in various industries.
