Rick Parker fd04fddd70 ENT-12072 ENT-12073: Check notary whitelist when resolving old identities and don't depend on network map availability first for old network parameters (#7781) 
Nodes currently will try and resolve network parameters from the network map and fail if it not available, rather than preferring the availability of a node they are currently interacting with.

A migrated notary identity could not be resolved on new nodes added post-migration, but the old identity is available in the network parameter notary whitelist.

Added a test that covers both bugs in a single reproduction test that simulates the scenario in which both were uncovered.

  • 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
