Run Iroha in one node

Is possible to run Iroha in a single node. You can use this approach If you want to do tests before running Iroha in four nodes

irohad --config configSingle/config.sample --genesis_block configSingle/genesis.block --keypair_name configSingle/node0

Additional Commands

If you like to clean and start fresh

irohad --config configSingle/config.sample --genesis_block configSingle/genesis.block --keypair_name  configSingle/node0 --overwrite_ledger

Run Iroha in four nodes

On each machine do the following:

Open the genesis.block file and update the 'address' entry to correspond the ip of each machine. For example, the entry:

{
   "peer":{
      "address":"99.230.31.239:10001",
      "peerKey":"bddd58404d1315e0eb27902c5d7c8eb0602c16238f005773df406bc191308929"
   }
}                            

will correspond to node0. Inspect the file node0.pub and see that peerkey is the same key written in node0.pub file. Update all peer entries with the corresponding ip address and 'nodeN.pub' key

One each machine create the folder config and copy the genesis.block and the config.sample

On each machine run (change 'node0' to make it correspond with the machine, i.e., machine 2 is node1, machine 3 is node2 and so on)

irohad --config config/config.sample --genesis_block config/genesis.block --keypair_name config/node0

Additional Commands

If you like to clean and start fresh

irohad --config config/config.sample --genesis_block config/genesis.block --keypair_name config/node0 --overwrite_ledger
