  • Flow framework to manage communication and negotiation between participants
  • Peer-to-peer network of nodes
  • "Notary" infrastructure to validate uniqueness and sequencing of transactions without global broadcast
  • Enables the development and deployment of distributed apps called CorDapps
  • Written in Kotlin, targeting the JVM

Getting started
