CORDA-866: Implement removal of stale nodes from network - backport (#3128)
* CORDA-866: Implement removal of stale nodes from network

Backported

* Implement removal of stale nodes from network

Add eventHorizon to NetworkParameters structure. Add republishing of
node info on 1 day intervals - it is treated by network map as heartbeat from node indicating if it's alive or not. Add removal of old node infos on network map signing.

* Add copy method to NetworkParameters data class

Add JvmOverloads annotation to the constructor, because it's data class
exposed in API

* Fix test

Corda

Corda

Corda is a decentralised database system in which nodes trust each other as little as possible.

Features

  • Smart contracts that can be written in Java and other JVM languages
  • 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

  1. Read the Getting Started documentation
  2. Run the Example CorDapp
  3. Read about Corda's Key Concepts
  4. Follow the Hello, World! tutorial
