I have created private ethreum blockchain,It is hosted in LAN network and connected with 3 nodes, i am using one main Node IP (e.g 192.168.1.27:8546) to connect my application(created using web3.js truffle) with blockchain but if that main Node is get down then how to connect with Other node using application??

  • simply, get the ip address of another node as you got the ip of main node. then you can interact with that chain. – Gopal ojha Apr 11 '18 at 10:37
  • yes, but it is not possible to check which Node is working and change IP accordingly every-time in application's config – Smit Thakur Apr 11 '18 at 10:48
  • use if else case for, if connected is true for one ip then use it otherwise go to next ip address. it works fine unless down all nodes. – Gopal ojha Apr 11 '18 at 11:49
