Creating a network from scratch

This section details easy to follow step by step instructions of how to setup one or more Smilo nodes from scratch for all new starters.

Let's go through step by step instructions to setup a Smilo node with Raft consensus.

Smilo with Raft consensus

  1. On each machine build Smilo as described in the Installing section. Ensure that PATH contains geth and bootnode

    $ git clone https://github.com/smilofoundation/Smilo.git
$ cd Smilo
$ make all
$ export PATH=$(pwd)/build/bin:$PATH

  2. Create a working directory which will be the base for the new node(s) and change into it

    $ mkdir fromscratch
$ cd fromscratch
$ mkdir new-node-1

  3. Generate one or more accounts for this node and take down the account address. A funded account may be required depending what you are trying to accomplish

    $ geth --datadir new-node-1 account new
 INFO [06-07|14:52:18.742] Maximum peer count                       ETH=25 LES=0 total=25
 Your new account is locked with a password. Please give a password. Do not forget this password.
 Passphrase: 
 Repeat passphrase: 
 Address: {679fed8f4f3ea421689136b25073c6da7973418f}
 Please note the keystore file generated inside new-node-1 includes the address in the last part of its filename.
 $ ls new-node-1/keystore
 UTC--2019-06-17T09-29-06.665107000Z--679fed8f4f3ea421689136b25073c6da7973418f

    !!! note You could generate multiple accounts for a single node, or any number of accounts for additional nodes and pre-allocate them with funds in the genesis.json file (see below)

  4. Create a genesis.json file see example here. The alloc field should be pre-populated with the account you generated at previous step

    $ vim genesis.json
... alloc holds 'optional' accounts with a pre-funded amounts. In this example we are funding the accounts 679fed8f4f3ea421689136b25073c6da7973418f (generated from the step above) and c5c7b431e1629fb992eb18a79559f667228cd055.
{
  "alloc": {
    "0x679fed8f4f3ea421689136b25073c6da7973418f": {
      "balance": "1000000000000000000000000000"
    },

 "timestamp": "0x00"
}

  5. Generate node key and copy it into datadir

    $ bootnode --genkey=nodekey
$ cp nodekey new-node-1/

  6. Execute below command to display enode id of the new node

    $ bootnode --nodekey=new-node-1/nodekey --writeaddress > new-node-1/enode
$ cat new-node-1/enode  
'70399c3d1654c959a02b73acbdd4770109e39573a27a9b52bd391e5f79b91a42d8f2b9e982959402a97d2cbcb5656d778ba8661ec97909abc72e7bb04392ebd8'

  7. Create a file called static-nodes.json and edit it to match this example. Your file should contain a single line for your node with your enode's id and the ports you are going to use for devp2p and raft. Ensure that this file is in your nodes data directory

    $ vim static-nodes.json
.... paste below lines with enode generated in previous step, port 21000;IP 127.0.0.1 and raft port set as 50000
[
  "enode://70399c3d1654c959a02b73acbdd4770109e39573a27a9b52bd391e5f79b91a42d8f2b9e982959402a97d2cbcb5656d778ba8661ec97909abc72e7bb04392ebd8@127.0.0.1:21000?discport=0&raftport=50000"
] 
$ cp static-nodes.json new-node-1

  8. Initialize new node with below command.

    $ geth --datadir new-node-1 init genesis.json
INFO [06-07|15:45:17.508] Maximum peer count                       ETH=25 LES=0 total=25

  9. Start your node by first creating a script as below and then starting it:

    $ vim startnode1.sh
... paste below commands. It will start it in the background.
#!/bin/bash
PRIVATE_CONFIG=ignore nohup geth --datadir new-node-1 --nodiscover --verbosity 5 --networkid 31337 --raft --raftport 50000 --rpc --rpcaddr 0.0.0.0 --rpcport 22000 --rpcapi admin,db,eth,debug,miner,net,shh,txpool,personal,web3,Smilo,raft --emitcheckpoints --port 21000 >> node.log 2>&1 &
$ chmod +x startnode1.sh 
$ ./startnode1.sh

    !!! note This configuration starts Smilo without privacy support as could be evidenced in prefix PRIVATE_CONFIG=ignore, please see below sections on how to enable privacy with privacy transaction managers.

    Your node is now operational and you may attach to it with below commands.

    $ geth attach new-node-1/geth.ipc

Adding additional node

  1. Complete steps 1, 2, 5, and 6 from the previous guide

    $ mkdir new-node-2
$ bootnode --genkey=nodekey2
$ cp nodekey2 new-node-2/nodekey
$ bootnode --nodekey=new-node-2/nodekey --writeaddress
56e81550db3ccbfb5eb69c0cfe3f4a7135c931a1bae79ea69a1a1c6092cdcbea4c76a556c3af977756f95d8bf9d7b38ab50ae070da390d3abb3d7e773099c1a9

  2. Retrieve current chains genesis.json and static-nodes.json. static-nodes.json should be placed into new nodes data dir

    $ cp static-nodes.json new-node-2

  3. Edit static-nodes.json and add new entry for the new node you are configuring (should be last)

    $ vim new-node-2/static-nodes.json 
.... append new-node-2's enode generated in step 1, port 21001;IP 127.0.0.1 and raft port set as 50001
[
  "enode://70399c3d1654c959a02b73acbdd4770109e39573a27a9b52bd391e5f79b91a42d8f2b9e982959402a97d2cbcb5656d778ba8661ec97909abc72e7bb04392ebd8@127.0.0.1:21000?discport=0&raftport=50000",

]

  4. Initialize new node as given below:

    $ geth --datadir new-node-2 init genesis.json

    p2pPort: 21000,
    raftId: 1,
    raftPort: 50000
}]
> exit

  6. Start your node by first creating a script as previous step and changing the ports you are going to use for Devp2p and raft.

    $ cp startnode1.sh startnode2.sh
$ vim startnode2.sh
..... paste below details
#!/bin/bash
PRIVATE_CONFIG=ignore nohup geth --datadir new-node-2 --nodiscover --verbosity 5 --networkid 31337 --raft --raftport 50001 --raftjoinexisting 2 --rpc --rpcaddr 0.0.0.0 --rpcport 22001 --rpcapi admin,db,eth,debug,miner,net,shh,txpool,personal,web3,Smilo,raft --emitcheckpoints --port 21001 2>>node2.log &
$ ./startnode2.sh

  7. Optional: share new static-nodes.json with all other chain participants

    $ cp new-node-2/static-nodes.json new-node-1

    Your additional node is now operational and is part of the same chain as the previously set up node.

Removing node

  1. Connect to an already running node of the chain and execute raft.cluster and get the RAFT_ID corresponding to the node that needs to be removed
  2. Run raft.removePeer(RAFT_ID)
  3. Stop the geth process corresponding to the node that was removed.
    $ geth attach new-node-1/geth.ipc

Smilo with Istanbul BFT consensus

  1. On each machine build Smilo as described in the Installing section. Ensure that PATH contains geth and boot node

    $ git clone https://github.com/smilofoundation/Smilo.git
$ cd Smilo
$ make all
$ export PATH=$(pwd)/build/bin:$PATH

  2. Install istanbul-tools

    $ mkdir fromscratchistanbul
$ cd fromscratchistanbul
$ git clone https://github.com/smilofoundation/istanbul-tools.git
$ cd istanbul-tools
$ make

  3. Create a working directory for each of the X number of initial validator nodes

    $ mkdir node0 node1 node2 node3 node4

  4. Change into the lead (whichever one you consider first) node's working directory and generate the setup files for X initial validator nodes by executing istanbul setup --num X --nodes --Smilo --save --verbose only execute this instruction once, i.e. not X times. This command will generate several items of interest: static-nodes.json, genesis.json, and nodekeys for all the initial validator nodes which will sit in numbered directories from 0 to X-1

    $ cd node0
$ ../istanbul-tools/build/bin/istanbul setup --num 5 --nodes --Smilo --save --verbose
validators

  5. Update static-nodes.json to include the intended IP and port numbers of all initial validator nodes. In static-nodes.json, you will see a different row for each node. For the rest of the installation guide, row Y refers to node Y and row 1 is assumed to correspond to the lead node

    $ cat static-nodes.json
.... update the IP and port numbers as give below...

  6. In each node's working directory, create a data directory called data, and inside data create the geth directory

    $ cd ..
$ mkdir -p node0/data/geth
$ mkdir -p node1/data/geth
$ mkdir -p node2/data/geth
$ mkdir -p node3/data/geth
$ mkdir -p node4/data/geth

  7. Now we will generate initial accounts for any of the nodes in the required node's working directory. The resulting public account address printed in the terminal should be recorded. Repeat as many times as necessary. A set of funded accounts may be required depending what you are trying to accomplish

    $ geth --datadir node0/data account new

Repeat passphrase: 
Address: {65a3ab6d4cf23395f544833831fc5d42a0b2b43a}

  8. To add accounts to the initial block, edit the genesis.json file in the lead node's working directory and update the alloc field with the account(s) that were generated at previous step

    $ vim node0/genesis.json
.... update the accounts under 'alloc'

}

  9. Next we need to distribute the files created in part 4, which currently reside in the lead node's working directory, to all other nodes. To do so, place genesis.json in the working directory of all nodes, place static-nodes.json in the data folder of each node and place X/nodekey in node (X-1)'s data/geth directory

    $ cp node0/genesis.json node1
$ cp node0/genesis.json node2
$ cp node0/genesis.json node3
$ cp node0/genesis.json node4
$ cp node0/static-nodes.json node0/data/
$ cp node0/static-nodes.json node1/data/
$ cp node0/static-nodes.json node2/data/
$ cp node0/static-nodes.json node3/data/
$ cp node0/static-nodes.json node4/data/
$ cp node0/0/nodekey node0/data/geth
$ cp node0/1/nodekey node1/data/geth
$ cp node0/2/nodekey node2/data/geth
$ cp node0/3/nodekey node3/data/geth
$ cp node0/4/nodekey node4/data/geth

  10. Switch into working directory of lead node and initialize it. Repeat for every working directory X created in step 3. The resulting hash given by executing geth init must match for every node

    !!! note This configuration starts Smilo without privacy support as could be evidenced in prefix PRIVATE_CONFIG=ignore, please see below sections on how to enable privacy with privacy transaction managers. Please note that istanbul-tools may be used to generate X number of nodes, more information is available in the docs.

    Your node is now operational and you may attach to it with geth attach node0/data/geth.ipc.

Adding additional validator

  1. Create a working directory for the new node that needs to be added

    $ mkdir node5

  2. Change into the working directory for the new node and run istanbul setup --num 1 --verbose --Smilo --save. This will generate the validator details including Address, NodeInfo and genesis.json

    $ cd node5
$ ../istanbul-tools/build/bin/istanbul setup --num 1 --verbose --Smilo --save

  4. Verify that the new validator has been added to the list of validators by running istanbul.getValidators()

    ... you can see below command now displays 6 node address as validators.
> istanbul.getValidators()

  5. Copy static-nodes.json and genesis.json from the existing chain. static-nodes.json should be placed into new nodes data dir

    $ cd node5
$ mkdir -p data/geth
$ cp ../node0/static-nodes.json data
$ cp ../node0/genesis.json .

  6. Edit static-nodes.json and add the new validators node info to the end of the file. New validators node info can be got from the output of istanbul setup --num 1 --verbose --Smilo --save command that was run in step 2. Update the IP address and port of the node info to match the IP address of the validator and port you want to use.

    $ vim data/static-nodes.json
...add new validate nodes details with correct IP and port details

Adding non-validator node

Same instructions as adding validator node excluding step 3 which proposes the node as validator.

Removing non-validator node

Just execute step 4 instruction from removing a validator node.

Adding privacy transaction manager

Tessera

  1. Build Smilo and install Tessera as described in the Installing section. Ensure that PATH contains geth and bootnode. Be aware of the location of the tessera.jar release file

    $ git clone https://github.com/smilofoundation/Smilo.git
$ cd Smilo
$ make all
$ export PATH=$(pwd)/build/bin:$PATH
$ cd ..
.... copy tessera jar to your desired destination and rename it as tessera
$ mv tessera-app-0.9.2-app.jar tessera.jar

  2. Generate new keys using java -jar /path-to-tessera/tessera.jar -keygen -filename new-node-1

    $ mkdir new-node-1t
$ cd new-node-1t
$ java -jar ../tessera.jar -keygen -filename new-node-1
Enter a password if you want to lock the private key or leave blank
Please re-enter the password (or lack of) to confirm

  3. Create new configuration file with newly generated keys referenced. Name it config.json as done in this example

    vim config.json
{
   "useWhiteList": false,
   "jdbc": {
       "username": "sa",
       "password": "",
       "url": "jdbc:h2:/yourpath/new-node-1t/db1;MODE=Oracle;TRACE_LEVEL_SYSTEM_OUT=0",
       "autoCreateTables": true
   },
   "serverConfigs":[
       {
           "app":"ThirdParty",
           "enabled": true,
           "serverAddress": "http://localhost:9081",

       }
   ],
   "keys": {
       "passwords": [],
       "keyData": [

Constellation

  1. Build Smilo and install Constellation as described in the Installing section. Ensure that PATH contains geth, bootnode, and constellation-node binaries

  2. Generate new keys with constellation-node --generatekeys=new-node-1

  3. Start your constellation node and send it into background with constellation-node --url=https://127.0.0.1:9001/ --port=9001 --workdir=. --socket=tm.ipc --publickeys=new-node-1.pub --privatekeys=new-node-1.key --othernodes=https://127.0.0.1:9001/ >> constellation.log 2>&1 &

  4. Start your node and send it into background with PRIVATE_CONFIG=tm.ipc nohup geth --datadir new-node-1 --nodiscover --verbosity 5 --networkid 31337 --raft --raftport 50000 --rpc --rpcaddr 0.0.0.0 --rpcport 22000 --rpcapi admin,db,eth,debug,miner,net,shh,txpool,personal,web3,Smilo,raft --emitcheckpoints --port 21000 2>>node.log &

    !!! note Constellation IPC bridge will be over a file name defined in your configuration: in above step #3 see option --socket=file-name.ipc. Your node is now able to send and receive private transactions, advertised public node key will be in the new-node-1.pub file.

    Your node is now operational and you may attach to it with geth attach new-node-1/geth.ipc.

Enabling permissioned configuration

Smilo ships with a permissions system based on a custom whitelist. Detailed documentation is available in Network Permissioning.
