Loan Application Cordapp - Kotlin

Architecture

Instructions for setting up

1. git clone https://github.com/vardan10/loan-Application-Cordapp.git
2. cd loan-Application-Cordapp
3. ./gradlew deployNodes - building may take upto a minute (it's much quicker if you already have the Corda binaries).
4. ./build/nodes/runnodes
5. In a new terminal - run partyA API Server ./gradlew runPartyAServer
6. In a new terminal - run partyB API Server ./gradlew runPartyBServer
7. In a new terminal - run partyC API Server ./gradlew runPartyCServer

At this point you will have a notary node running as well as three other nodes. The nodes take about 20-30 seconds to finish booting up.There should be 4 console windows in total. (Plus 3 terminal for API)
