Starting a Full Node
Minimum system requirements:
- Any modern Linux distribution (RHEL 8 or Fedora 36 are preferred)
- A quad-core CPU
- 16 GB of RAM
- 320 GB of storage
There are a couple of ways to initialize and start a full node
- 2.Initialize and start a full node manually
- 1.
mkdir $HOME/.onomy/scripts
cd $HOME/.onomy/scripts
wget https://raw.githubusercontent.com/onomyprotocol/onomy/main/deploy/scripts/allow-cors.sh
wget https://raw.githubusercontent.com/onomyprotocol/onomy/main/deploy/scripts/init-mainnet-full-node.sh
wget https://raw.githubusercontent.com/onomyprotocol/onomy/main/deploy/scripts/start-onomyd.sh
wget https://raw.githubusercontent.com/onomyprotocol/onomy/main/deploy/scripts/stop-onomyd.sh
2. Add executable permissions to the scripts using
chmod +x *3. Download genesis file
wget https://raw.githubusercontent.com/onomyprotocol/onomy/main/genesis/mainnet/genesis-mainnet-1.json
4. Run init-mainnet-full-node.sh script to initiate a new full node
bash init-mainnet-full-node.shThis script will ask you for several details
- Node Name [Text]: A name for your full node
- Seed IPs [Comma separated list of IPs]: IP Addresses of seed nodes, There are a couple of IPs pre-configured, If you want to point your node to custom Seed node, you can do that here
- Your IP Address [IP Address]
After the script is done, you will find node-id in the output. Make sure to take a note of the node id as you might need it afterwards. If you forgot to save your node id, you can find it using
onomyd tendermint show-node-id4. [Optional] you can allow CORS using the script
allow-cors.sh5. You can start and stop the node using
start-onomyd.sh and stop-onomyd.sh. When you first start the node, give it enough time to sync with the blockchain- 1.Initialize onomy node and config files
onomyd init <node name> --chain-id onomy-mainnet-1- 2.Copy Genesis file from onomy repo
If Onomy Github repository was downloaded in previous step, copy genesis file from the repo
cp onomy/genesis/genesis-mainnet-1.json $HOME/.onomy/config/genesis.jsonOtherwise, download genesis file using wget
wget https://raw.githubusercontent.com/onomyprotocol/onomy/main/genesis/mainnet/genesis-mainnet-1.json
cp genesis-mainnet-1.json $HOME/.onomy/config/genesis.json
- 3.Change config to add various details
crudini --set $HOME/.onomy/config/config.toml p2p addr_book_strict false
crudini --set $ HOME/.onomy/config/config.toml p2p external_address "\"tcp://<ip-address>:26656\""
crudini --set $ HOME/.onomy/config/config.toml p2p seeds "\”[email protected]:26656, [email protected]:26656\”"
crudini --set $ HOME/.onomy/config/config.toml rpc laddr "\"tcp://0.0.0.0:26657\""
crudini --set $HOME/.onomy/config/app.toml grpc enable true
crudini --set $HOME/.onomy/config/app.toml grpc address "\”0.0.0.0:9191\”"
crudini --set $HOME/.onomy/config/app.toml api enable true
crudini --set $HOME/.onomy/config/app.toml api swagger true
- 4.Setup state-sync (Optional)
We can setup state-sync to quickly sync up the node
These are the IP addresses for state sync nodes:
52.70.182.125, 44.195.221.88Open one RPC endpoint of one of the state-sync nodes to get the details of latest block: http://52.70.182.125:26657/block.
- Get latest block height from result.block.header.height parameter and latest block hast from result.block_id.hash parameter
- Change the following parameters in config.toml file
crudini --set $ONOMY_NODE_CONFIG statesync enable true
crudini --set $ONOMY_NODE_CONFIG statesync rpc_servers "\" [email protected]:26657,[email protected]:26657\""
crudini --set $ONOMY_NODE_CONFIG statesync trust_height <block height from previous step>
crudini --set $ONOMY_NODE_CONFIG statesync trust_hash "\" <block hash from previous step> \""
crudini --set $ONOMY_NODE_CONFIG statesync discovery_time "\"60s\""
crudini --set $ONOMY_NODE_CONFIG statesync chunk_request_timeout "\"60s\""
crudini --set $ONOMY_NODE_CONFIG statesync chunk_fetchers "\"10\""
- 5.Start the node
- Increase open file limit to more than 65535
ulimit –n 65536- Start onomyd
onomyd start- If you are using cosmovisor then start cosmovisor
cosmovisor startYou should be good to go! You can check the status of the Onomy chain by running:
curl http://localhost:26657/status
Your node is fully synced when
catching_up is false.You can also open the
http://localhost:26657 in your browser and check available end-points
