# Validator Setup
|
|
|
|
## Install required software packages
|
|
|
|
```sh
|
|
# Update Ubuntu
|
|
sudo apt update
|
|
sudo apt upgrade -y
|
|
|
|
# Install required software packages
|
|
sudo apt install git curl build-essential make jq -y
|
|
```
|
|
|
|
---
|
|
|
|
## Install Go
|
|
|
|
```sh
|
|
# Remove any existing installation of `go`
|
|
sudo rm -rf /usr/local/go
|
|
|
|
# Install Go version 1.17.2
|
|
curl https://dl.google.com/go/go1.17.2.linux-amd64.tar.gz | sudo tar -C/usr/local -zxvf -
|
|
|
|
# Update env variables to include go
|
|
cat <<'EOF' >>$HOME/.profile
|
|
export GOROOT=/usr/local/go
|
|
export GOPATH=$HOME/go
|
|
export GO111MODULE=on
|
|
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
|
|
EOF
|
|
|
|
source $HOME/.profile
|
|
```
|
|
|
|
Check the version of go installed
|
|
|
|
```sh
|
|
go version
|
|
|
|
# Should return something like: go version go1.17.2 linux/amd64
|
|
```
|
|
|
|
---
|
|
|
|
## Install `chibaclonk`
|
|
|
|
```sh
|
|
git clone https://github.com/vulcanize/chiba-clonk.git
|
|
cd chiba-clonk
|
|
|
|
# Checkout main branch
|
|
git fetch --all
|
|
git checkout main
|
|
|
|
# Build and install chibaclonk
|
|
make install
|
|
```
|
|
|
|
Verify your installation
|
|
|
|
```sh
|
|
chibaclonkd version --long
|
|
```
|
|
|
|
On running the above command, you should see a similar response like this. Make sure that the *version* and *commit
|
|
hash* are accurate
|
|
|
|
```sh
|
|
name: chibaclonk
|
|
server_name: chibaclonkd
|
|
```
|
|
|
|

|
|
|
|
## Initialize Validator Node
|
|
|
|
**Not required if you have already initialized before**
|
|
|
|
```sh
|
|
# Initialize the validator node
|
|
chibaclonkd init <your-node-moniker> --chain-id chibaclonk_81337-4
|
|
```
|
|
|
|
Running the above commands will initialize the validator node with default configuration. The config files will be saved in the default location (`~/.chibaclonkd/config`).
|
|
|
|
**NOTE:** Backup your node and validator keys. You will need to use these keys at a later point in time.
|
|
|
|
---
|
|
|
|
## Overwrite Validator Initialization from previous testnet
|
|
|
|
**Required for `chibaclonk_81337-4`**
|
|
|
|
First we have to reset the previous genesis state (only because the `chibaclonk_81337-3` testnet failed) whereafter we can initialize the validator node for `chibaclonk_81337-4`
|
|
|
|
```sh
|
|
# Stop your node (in case it was still running)
|
|
systemctl stop chibaclonkd
|
|
|
|
# Keep a backup of your old validator directory
|
|
cp -a ~/.chibaclonkd ~/backup-chibaclonk_81337-2
|
|
|
|
# Reset the state of your validator
|
|
chibaclonkd tendermint unsafe-reset-all --home $HOME/.chibaclonkd
|
|
|
|
# Remove your previous genesis transactions
|
|
rm $HOME/.chibaclonkd/config/gentx/gentx*.json
|
|
|
|
# Overwrite your genesis state with the new chain-id
|
|
chibaclonkd init --overwrite <your-node-moniker> --chain-id chibaclonk_81337-4
|
|
```
|
|
|
|
Running the above commands will re-initialize the validator node with default configuration. The config files will be saved in the default location (`~/.chibaclonkd/config`).
|
|
|
|
**NOTE:** Backup your node and validator keys. You will need to use these keys at a later point in time.
|
|

|
|
|
|
## Create Account keys
|
|
|
|
If you have participated in a previous testnet and have a mnemonic phrase, use below command to recover your account:
|
|
|
|
```sh
|
|
chibaclonkd keys add <key-name> --recover
|
|
```
|
|
|
|
To create a new account use:
|
|
|
|
```sh
|
|
chibaclonkd keys add <key-name>
|
|
```
|
|
|
|
**NOTE:** Save the `mnemonic` and related account details (public key). You will need to use the mnemonic and / or private key to recover accounts at a later point in time.
|
|
|
|
---
|
|
|
|
## Add Genesis Account
|
|
|
|
**NOTE:** Don't add more than 12,900 CHK , if you add more than that, your gentx will be ignored.
|
|
|
|
```sh
|
|
chibaclonkd add-genesis-account <key-name> 12900000000000000000000achk --keyring-backend os
|
|
```
|
|
|
|
Create Your `gentx` transaction file
|
|
|
|
```sh
|
|
chibaclonkd gentx <key-name> 12900000000000000000000achk \
|
|
--pubkey=$(chibaclonkd tendermint show-validator) \
|
|
--chain-id="chibaclonk_81337-4" \
|
|
--moniker="<your-moniker-name>" \
|
|
--website="<your-validator-website>" \
|
|
--details="<your-validator-description>" \
|
|
--identity="<your-keybase-public-key>" \
|
|
--commission-rate="0.10" \
|
|
--commission-max-rate="0.20" \
|
|
--commission-max-change-rate="0.01" \
|
|
--min-self-delegation="1"
|
|
```
|
|
|
|
**NOTE:**
|
|
|
|
- `<key-name>` and `chain-id` are required. other flags are optional
|
|
- Don't change the amount value while creating your gentx
|
|
- Genesis transaction file will be saved in `~/.chibaclonkd/config/gentx` folder
|
|
|

|
|
|
|
## Submit Your gentx
|
|
|
|
Submit your `gentx` file to the [https://github.com/vulcanize/laconic-testnet]() repository in the following format:
|
|
`<validator-moniker>-gentx.json`
|
|
|
|
**NOTE:** (Do NOT use spaces in the file name)
|
|
|
|
To submit the gentx file, follow the below process:
|
|
|
|
- Fork the [https://github.com/vulcanize/laconic-testnet]() repository
|
|
- Upload your gentx file in the `chibaclonk_81337-4/config/gentxs` folder
|
|
- Submit Pull Request to [https://github.com/vulcanize/laconic-testnet]() with name `ADD <your-moniker> gentx`
|
|
|
|
The genesis file will be published in the `chibaclonk_81337-4/config/` folder within the [https://github.com/vulcanize/laconic-testnet]() repository.

# CONTINUE WITH BELOW STEPS ONLY AFTER GENESIS FILE HAS BEEN PUBLISHED
|
|
|
|
## Adjust validator node configuration
|
|
|
|
```sh
|
|
# Set seed & peers variable
|
|
seeds="<seeds node list here>"
|
|
peers="<peers node list here>"
|
|
|
|
# Update seeds, persistent_peers and prometheus parameters in config.toml
|
|
sed -i.bak -e "s/^seeds *=.*/seeds = \"$seeds\"/; s/^persistent_peers *=.*/persistent_peers = \"$peers\"/; s/^prometheus *=.*/prometheus = true/" $HOME/.chibaclonkd/config/config.toml
|
|
