IOTA Chrysalis mainnet and testnet are public IOTA Networks where you can develop permissionless applications based on the Tangle. However, there can be situations where you would like to run a Private IOTA Network (Private Tangle) so that only a limited set of stakeholders or Nodes can participate. To support the IOTA Community working on these kind of scenarios, a set of Docker-based tools and pre-configured setups allow the deployment of a (hornet-based) Private Tangle in "one click". Running a Private Tangle requires to identify the organizations allowed (alongside with the needed requirements) to deploy an IOTA node. Nodes in a Private Tangle are peered between them, while the transactions generated inside this network are shared, validated and stored only across the nodes that are part of the network.
