Install Validator Testnet Republic Ai

1. System Preparation

sudo apt update && sudo apt upgrade -y
sudo apt install docker.io -y

2. Pull the published image

docker pull ghcr.io/republicai/republicd:0.1.0

3. Initialize data and fetch genesis

REPUBLIC_HOME="$HOME/.republic"
mkdir -p "$REPUBLIC_HOME"

docker run --rm \
  --user 0:0 \
  -v "$REPUBLIC_HOME:/home/republic/.republic" \
  ghcr.io/republicai/republicd:0.1.0 \
  init my-node --chain-id raitestnet_77701-1 --home /home/republic/.republic

sudo curl -s https://raw.githubusercontent.com/RepublicAI/networks/main/testnet/genesis.json -o "$REPUBLIC_HOME/config/genesis.json"

4. Configure state sync (recommended for faster sync)

SNAP_RPC="https://statesync.republicai.io"
LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height)
BLOCK_HEIGHT=$((LATEST_HEIGHT - 1000))
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)

sudo sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \
s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC\"| ; \
s|^(trust_height[[:space:]]+=[[:space:]]+).*$|\1$BLOCK_HEIGHT| ; \
s|^(trust_hash[[:space:]]+=[[:space:]]+).*$|\1\"$TRUST_HASH\"|" "$REPUBLIC_HOME/config/config.toml"

PEERS="e281dc6e4ebf5e32fb7e6c4a111c06f02a1d4d62@3.92.139.74:26656,cfb2cb90a241f7e1c076a43954f0ee6d42794d04@54.173.6.183:26656,dc254b98cebd6383ed8cf2e766557e3d240100a9@54.227.57.160:26656"
sudo sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" "$REPUBLIC_HOME/config/config.toml"

5. Custom port (optional, if needed)

PORT=170
sed -i -e "s%:26657%:${PORT}57%" $REPUBLIC_HOME/config/client.toml
sed -i -e "s%:26658%:${PORT}58%; s%:26657%:${PORT}57%; s%:6060%:${PORT}60%; s%:26656%:${PORT}56%; s%:26660%:${PORT}61%" $REPUBLIC_HOME/config/config.toml
sed -i -e "s%:1317%:${PORT}17%; s%:9090%:${PORT}90%" $REPUBLIC_HOME/config/app.toml

sed -i \
-e 's|^pruning *=.*|pruning = "custom"|' \
-e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \
-e 's|^pruning-keep-every *=.*|pruning-keep-every = "0"|' \
-e 's|^pruning-interval *=.*|pruning-interval = "10"|' \
$REPUBLIC_HOME/config/app.toml

sed -i 's|^indexer *=.*|indexer = "null"|' $REPUBLIC_HOME/config/config.toml

6. Fix ownership to match container user (UID 1001)

sudo chown -R 1001:1001 "$REPUBLIC_HOME"

7. Run the node

docker run -d --name republicd \
  --network host \
  -v "$REPUBLIC_HOME:/home/republic/.republic" \
  ghcr.io/republicai/republicd:0.1.0 \
  start --home /home/republic/.republic --chain-id raitestnet_77701-1

8. Check logs

docker logs -f republicd

9. Create wallet

docker exec -it republicd bash
republicd keys add wallet

#get pubkey (save)
republicd comet show-validator

exit

10. Create validator.json

nano $HOME/.republic/validator.json

#fill your info
{
  "pubkey": {your_pubkey},
  "amount": "1000000000000000000arai",
  "moniker": "your_moniker",
  "identity": "your_keybase",
  "website": "your_website",
  "security": "your_email",
  "details": "your_detail_validator",
  "commission-rate": "0.05",
  "commission-max-rate": "0.2",
  "commission-max-change-rate": "0.05",
  "min-self-delegation": "1"
}

11. Create validator

docker exec -it republicd bash

republicd tx staking create-validator .republic/validator.json \
  --chain-id=raitestnet_77701-1 \
  --gas=auto \
  --gas-adjustment=1.5 \
  --gas-prices="2500000000arai" \
  --from=wallet
