Test- and Development Networks

The IOTA Foundation and the IOTA community members operate several development networks (DevNets) in which different stages of the IOTA protocol and new applications can be tested and optimized. This is a playground for developers and researchers. The assets used in testnets are simply testnet tokens with no real-world value.

IOTA 2.0 Decentralized DevNet

This is the implementation of the upcoming fully decentralized IOTA 2.0 protocol. This network does not use or need a coordinator. It utilizes testnet IOTA tokens without value to fine-tune, test, and optimize the upcoming development stage of the IOTA protocol together with the IOTA community. This network is composed of GoShimmer nodes. While many nodes in the 2.0 DevNet are run and maintained by the IOTA Foundation, anyone can contribute by running their own nodes. Having a larger network is beneficial for testing newly researched and developed concepts and ideas, catching bugs, and ironing out finished components.

IOTA 1.5 DevNet

The official IOTA 1.5 DevNet. In this DevNet, the coordinator and some public nodes are run by the IOTA Foundation. It can also be used to test apps for IOTA 1.5. The full documentation for the IOTA 1.5 DevNet can be found here:
