Validator Node Setup

Validators have weekly tasks, different tasks have different points, and the task list can be found here:

https://initia-xyz.notion.site/The-Initiation-Validator-Tasks-6d88ab0034644473907435662f9285b3initia-xyz.notion.site

Official documentation:

https://docs.initia.xyz/run-initia-node/running-initia-nodedocs.initia.xyz

Validator configuration requirements:

CPU: 4 cores

Memory: 32GB RAM

Disk: 2 TB NVMe/SSD with bandwidth greater than 1000 MiBps

Network bandwidth: 100 Mbps

Current initiad version: v0.2.21

Install the dependent environment

Install go

wget -c https://golang.org/dl/go1.22.3.linux-amd64.tar.gz  -O - | sudo tar -xz -C /usr/local

echo "export PATH=$PATH:/usr/local/go/bin" >> /etc/profile && source /etc/profile

go version

Check go version

go version

Install Dependencies

sudo apt update && sudo apt install curl build-essential make gcc jq git -y

Compile the initiad binary

git clone https://github.com/initia-labs/initia.git
cd initia
git checkout  v0.2.21
make install  # Or execute make build and move the generated binary to your $PATH path

Check version

initiad version

Initialization

initiad init $moniker --chain-id=initiation-1
initiad config set client chain-id initiation-1

Download Genesis File

curl -s https://snapshot.kubenode.xyz/testnet/initia/genesis.json >  ~/.initia/config/genesis.json

Setting up peer and seed

PEERS=`curl -sS  https://initia-rpc.kubenode.xyz/net_info  | jq -r '.result.peers[] | "\(.node_info.id)@\(.remote_ip):\(.node_info.listen_addr)"' | awk -F ':' '{print $1":"$(NF)}' | sed -z 's|\n|,|g;s|.$||'`


sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.initia/config/config.toml
sed -i.bak -e "s/^seeds *=.*/seeds = \"$seeds\"/" ~/.initia/config/config.toml

Modify the default port (optional)

To prevent port conflicts, you can modify the port and set a port prefix, such as starting with 61:

PREFIX_PORT="61"

sed -i.bak -e "s%:1317%:${PREFIX_PORT}317%g;
s%:8080%:${PREFIX_PORT}080%g;
s%:9090%:${PREFIX_PORT}090%g;
s%:9091%:${PREFIX_PORT}091%g;
s%:8545%:${PREFIX_PORT}545%g;
s%:8546%:${PREFIX_PORT}546%g;
s%:6065%:${PREFIX_PORT}065%g" ~/.initia/config/app.toml

sed -i.bak -e "s%:26658%:${PREFIX_PORT}658%g;
s%:26657%:${PREFIX_PORT}657%g;
s%:6060%:${PREFIX_PORT}060%g;
s%:26656%:${PREFIX_PORT}656%g;
s%:26660%:${PREFIX_PORT}660%g" ~/.initia/config/config.toml

Set the prune parameter to reduce the data size (optional)

pruning="custom" && \
pruning_keep_recent="100" && \
pruning_keep_every="0" && \
pruning_interval="10" && \
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.initia/config/app.toml && \
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.initia/config/app.toml && \
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" $HOME/.initia/config/app.toml && \
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.initia/config/app.toml

Fast Sync from Snapshot

curl -C - -OL https://snapshot.kubenode.xyz/testnet/initia/initia_latest.tar.lz4

(This allows you to resume downloading from a breakpoint. If the download is interrupted, just re-execute this command.)

initiad tendermint unsafe-reset-all --home ~/.initia --keep-addr-book

# Execute after download is complete
lz4 -c -d initia_latest.tar.lz4 | tar -x -C ~/.initia

Add the program to the systemd daemon

cat > /etc/systemd/system/initiad.service << EOF
[Unit]
Description=initia daemon
After=network-online.target
[Service]
User=$USER
ExecStart=$(which initiad) start
Restart=on-failure
RestartSec=3
LimitNOFILE=10000
[Install]
WantedBy=multi-user.target
EOF

Reload the configuration file and add the startup

sudo systemctl daemon-reload && sudo systemctl enable initiad

Start the validator node

sudo systemctl start initiad

View logs

sudo journalctl -u initia -f

View Sync Status

curl -s localhost:26657/status | jq .result | jq .sync_info

Note that if you have not changed the default port, the RPC port defaults to 26657. If you have changed the port as described in the Change the default port (optional) section, the RPC port defaults to 61657. You can view the port you defined in the ~/.initia/config/config.toml configuration file.

You can visit the block browser to view the latest height. When the current height queried by this command is consistent with the official height, you can create a validator.

Official block explorer:

Initia Explorer | Initia ScanInitia

If you still can't sync properly and have peer connection problems, you can use my addrbook or peer list here.

Peers | Node.Studydocs.node.study

Addrbook | Node.Studydocs.node.study

View currently active peers:

curl -sS  https://initia-rpc.kubenode.xyz/net_info  | jq -r '.result.peers[] | "\(.node_info.id)@\(.remote_ip):\(.node_info.listen_addr)"' | awk -F ':' '{print $1":"$(NF)}' | sed -z 's|\n|,|g;s|.$||'

Edit the configuration file and add the persistent peer list

PEERS="<Put the peer list output from the previous command here>"

sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" ~/.initia/config/config.toml

Then restart initiad:

sudo systemctl restart initiad

Check again whether the log is synchronized normally:

sudo journalctl -u initia -f

Create validator

When the local height is consistent with the official height, you can create a validator. We need to create a wallet first.

initiad keys add $WALLET_NAME

Remember to back up the output mnemonic information.

Then copy the wallet address and go here to get faucet.

https://faucet.testnet.initia.xyz/faucet.testnet.initia.xyz

Execute the create operation

initiad tx mstaking create-validator --node tcp://localhost:26657  \
        --amount=1000000uinit \
        --pubkey=$(initiad tendermint show-validator) \
        --moniker=$YOUR_NODE_NAME \
        --chain-id=initiation-1 \
        --commission-rate=0.05 \
        --commission-max-rate=0.10 \
        --commission-max-change-rate=0.01 \
        --from=$WALLET_NAME \
        --gas 500000 \
        --fees 300000uinit

(1000000uinit is 1 token)

Optional parameters:

--identity  # Validator logo, which can be created from https://keybase.io/
--website=  # Your website link
--security-contact  # Contact Email

If created successfully, you can find your validator name in the block browser:

https://scan.testnet.initia.xyz/initiation-1

Useful commands

Stake more tokens to a validator

initiad tx mstaking delegate <Validator Address> 1000000uinit --from <WALLET_NAME> -y --fees 200000uinit --gas 500000

(1000000uinit is 1 coin, modify it according to your needs, and run initiad tendermint show-validator to view the validator address)

Unjail

initiad tx slashing unjail  --from <WALLET_NAME> --gas 500000 --fees 200000uinit 

Vote

initiad tx gov vote <Proposal ID> yes --from <WALLET_NAME> --chain-id initiation-1 --gas-adjustment 1.4 --gas=2000000 --fees=563000move/944f8dd8dc49f96c25fea9849f16436dcfa6d564eec802f3ef7f8b3ea85368ff  --node tcp://localhost:53457 -y
