Setting up a new network

Creating a new network from genesis
This document describes in details how to configure a genesis network with any amount of participants.
Requirements
Hardware requirements
Minimal:
1GB RAM
25GB of disk space
1.4 GHz CPU
Recommended (for highload applications):
2GB RAM
100GB SSD
x64 2.0 GHz 2v CPU
Operating System
Current delivery is compiled and tested for Ubuntu 20.04 LTS so we recommend using this distribution for now. In the future, it will be possible to compile the application for a wide range of operating systems thanks to the Go language.
Deployment steps
Setting up nodes
All participants should setup their nodes using default genesis and empty list of peers.
Generating genesis file
1.Participants must choose <chain_id> for the network.
2.Each participant (one by one) should:
Generate local keys for the future account:
Command cheqd-noded keys add <key_name>
Example cheqd-noded keys add alice
(Each participant except the first one) Get genesis config from the another participant:
Location on the previous participant's machine: $HOME/.cheqdnode/config/genesis.json
Destination folder on the current participant's machine: $HOME/.cheqdnode/config/
(Each participant except the first one) Get genesis node transactions from the previous participant:
Location on the previous participant's machine: $HOME/.cheqdnode/config/gentx/
Destination folder on the current participant's machine: $HOME/.cheqdnode/config/gentx/
Add a genesis account with a public key:
Command: cheqd-noded add-genesis-account <key_name> 10000000cheq,100000000stake
Example: cheqd-noded add-genesis-account alice 10000000cheq,100000000stake
Generate genesis node transaction:
Command: cheqd-noded gentx <key_name> 1000000stake --chain-id <chain_id>
Example: cheqd-noded gentx alice 1000000stake --chain-id cheqd-node
TODO: Node owner should specify gas prices here. This work is in progress.
3.The last participant:
Add genesis node transactions into genesis:
Command: cheqd-noded collect-gentxs
Verify genesis:
Command: cheqd-noded validate-genesis
Share genesis with other nodes:
Location on the last participant's machine: $HOME/.cheqdnode/config/genesis.json
Sharing peer list
All participants should share their peer info with each other. See node setup instruction for more information.
Updating genesis and persistent peers
Each participant should:
Stop the node: systemctl stop cheqd-noded
Make sure the node is stopped systemctl status cheqd-noded
Update the genesis file:
File location:
Deb destribution: /etc/cheqd-node/genesis.json
Binary destribution: $HOME/.cheqdnode/config/genesis.json
Update peer list:
Open node's config file:
Deb destribution: /etc/cheqd-node/config.toml
Binary destribution: $HOME/.cheqdnode/config/config.toml
Search for persistent_peers parameter and set it's value to a comma separated list of peers.
Format: <node-0-id>@<node-0-ip>, <node-1-id>@<node-1-ip>, <node-2-id>@<node-2-id>, <node-3-id>@<node-3-id>.
Domain names can be used instead of IP adresses.
Example:
1
persistent_peers = "[email protected]:26656, [email protected]:26656, [email protected]:26656, [email protected]:26656"
Copied!
Start node: systemctl start cheqd-noded
Make sure the node process is running: systemctl status cheqd-noded
Congratulations, you should have node(s) deployed and running on a network if the above steps succeed.
