Distributed workflows
LetsFlow can run distributed workflows, where parties are participating on a process on their own on-premise node. All events are shared peer-to-peer between nodes. The LTO Network hybrid blockchain ensures that there is consensus about the order of events and protects against data tempering.
Please read the LTO Network documentation for information about creating an event chain and signing events.
Any LetsFlows object can be used as event body
