Install Go Install App and build Set variables Initialize the node (part 1) Initialize the node (part 2) Snapshot Create service to START and STOP Now get synced and check Create or recover a wallet Create your validator

STEP 1 Update your server to get the latest version

sudo apt update && sudo apt upgrade -y

STEP 2 Install packages

sudo apt install git curl wget tar lz4 unzip jq build-essential pkg-config clang bsdmainutils make ncdu -y

STEP 3 Install Go

Go is a programming language allowing each node of the Cosmos ecosystem to operate.
Go is a compiled and concurrent programming language inspired by C and Pascal.
This language was developed by Google from an initial concept by Robert Griesemer, Rob Pike and Ken Thompson.

cd $HOME
version="1.19.6"
wget "https://golang.org/dl/go$version.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$version.linux-amd64.tar.gz"
rm "go$version.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile

Check GO version, it must return : go version go1.19.6 linux/amd64

STEP 4 Install App and build

Here we will install the node for Gravity_Bridge with this binary version : GRAVITY HAVE A SPECIAL PROCESS TO INSTALL PLEASE HAVE A LOOK
THERE https://github.com/Gravity-Bridge/Gravity-Docs/blob/main/docs/setting-up-a-fullnode.md

Please be sure to install the latest version one last minute version can be published ! Please check by yourself here...

cd $HOME
git clone GRAVITY HAVE A SPECIAL PROCESS TO INSTALL PLEASE HAVE A LOOK 
THERE https://github.com/Gravity-Bridge/Gravity-Docs/blob/main/docs/setting-up-a-fullnode.md 
cd gravity-bin 
git checkout GRAVITY HAVE A SPECIAL PROCESS TO INSTALL PLEASE HAVE A LOOK 
THERE https://github.com/Gravity-Bridge/Gravity-Docs/blob/main/docs/setting-up-a-fullnode.md 
make install

Check if the binary "gravity" version GRAVITY HAVE A SPECIAL PROCESS TO INSTALL PLEASE HAVE A LOOK
THERE https://github.com/Gravity-Bridge/Gravity-Docs/blob/main/docs/setting-up-a-fullnode.md has been correctly installed

STEP 5 Set variables

What does moniker mean?
A personal name or nickname. This name (moniker) will appear in the blockchain explorer.

SPACE in your moniker will create errors

GRAVITY_BRIDGE_MONIKER="Replace_AVIAONE_by_your_name"

Top page

STEP 6 Initialize the node (part 1)

We are now ready to initialze the node


gravity init $GRAVITY_BRIDGE_MONIKER --chain-id gravity-bridge-3

Top page

STEP 7 Initialize the node (part 2)

Set minimum gas price

sed -i -e "s|^minimum-gas-prices *=.*|minimum-gas-prices = \"0ugraviton\"|" $HOME/.gravity/config/app.toml

Download genesis

wget -O $HOME/.gravity/config/genesis.json "https://services.gravity-bridge-3.gravity.aviaone.com/genesis.json"

Download addrbook

wget -O $HOME/.gravity/config/addrbook.json "https://services.gravity-bridge-3.gravity.aviaone.com/addrbook.json"

Add Seeds

SEEDS="258f523c96efde50d5fe0a9faeea8a3e83be22ca@seed.gravity-bridge-3.gravity.aviaone.com:10266,86bd5cb6e762f673f1706e5889e039d5406b4b90@gravity.seed.node75.org:10556,ade4d8bc8cbe014af6ebdf3cb7b1e9ad36f412c0@seeds.polkachu.com:14256"
sed -i -e "s|^seeds *=.*|seeds = \"$SEEDS\"|" $HOME/.gravity/config/config.toml

Change ports

Advanced users ONLY !

Clear Data

gravity tendermint unsafe-reset-all $HOME/.gravity --keep-addr-book

Top page

STEP 8 Create service to START and STOP (/etc/systemd/system)

This will let you start and stop your node with /etc/systemd/system

sudo tee /etc/systemd/system/gravity.service > /dev/null <<EOF
[Unit] 
Description=GRAVITY_BRIDGE\n 
After=network.target 
[Service] 
Type=simple
User=$USER
ExecStart=$(which gravity) start 

Restart=on-failure
RestartSec=10
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

sudo systemctl enable gravity 
sudo systemctl daemon-reload

This command will start your node

Do not use it now if you are going to use below : Snapshot | State Sync (because your node shouldn't start now... but after the Snapshot | State Sync)

sudo systemctl restart gravity && journalctl -u gravity -f --no-hostname -o cat

Top page

STEP 9 SNAPSHOT SNAPSHOT (After do no use STATE SYNC if you get synced, this is make no sense !)

How to use ?
The best way is just copy and past this code below in your terminal and that's it ! Your snapshot will be done.

SNAPSHOT Gravity_Bridge (Chain ID : gravity-bridge-3)

(updated every 24 hours)

mv $HOME/.gravity/priv_validator_state.json.backup $HOME/.gravity/data/priv_validator_state.json
sudo systemctl start gravity && sudo journalctl -u gravity -f --no-hostname -o cat

Top page

STEP 9 STATE SYNC STATE SYNC (After do not use SNAPSHOT if you get synced, this is make no sense !)

How to use ?
The best way is just copy and past this code below in your terminal and that's it ! Your StateSync will be done.

Please be sure to use the latest binary version :

Optional to clean your previous State Sync

sed -i "/\[statesync\]/, /^enable =/ s/=.*/= false/;\
/^rpc_servers =/ s|=.*|= \"\"|;\
/^trust_height =/ s/=.*/= 0/;\
/^trust_hash =/ s/=.*/= \"\"/" $HOME/.gravity/config/config.toml

sudo systemctl stop gravity 
SNAP_RPC="https://rpc.gravity-bridge-3.gravity.aviaone.com:443"
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)

Check if you get a positive return

echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH

Copy and past !

sed -i "/\[statesync\]/, /^enable =/ s/=.*/= true/;\
/^rpc_servers =/ s|=.*|= \"$SNAP_RPC,$SNAP_RPC\"|;\
/^trust_height =/ s/=.*/= $BLOCK_HEIGHT/;\
/^trust_hash =/ s/=.*/= \"$TRUST_HASH\"/" $HOME/.gravity/config/config.toml

Reset all data

sudo systemctl stop gravity && gravity tendermint unsafe-reset-all --home $HOME/.gravity --keep-addr-book

Start Sync

sudo systemctl start gravity && journalctl -u gravity -f --no-hostname -o cat

Watch your logs and be patient it can take 5 minutes.... !!

STEP 10 Now get synced and check

With the command used just above, your node just started, now BE PATIENT your node has started to work and will need time to get synced on the last block.

First check your logs and have a look at what's going on !

You should see some output like this which confirm that your node is indexing blocks

### indexed block exents height= module=txindex

How to check if your node is already fully synced? ?

gravity status 2>&1 | jq .SyncInfo

The current block number is : and the last block app hash is :

true mean syncing on the way, and true is NOT SYNCED

You will see an output with :

"catching_up": false

If you get true instead of false, please wait... it's not done yet, it's on the way...

true mean syncing on the way, and true is NOT SYNCED

The current block number is : and the last block app hash is :

Top page

STEP 11 Create or recover a wallet

Why it's better to get synced before to create or recover a wallet ?
Because when your wallet will be created or recovered, if you are not synced, you will not be able to check the balance !

Create Wallet

gravity keys add name_wallet

Recover Wallet

gravity keys add name_wallet --recover

Top page

STEP 12 Create your validator (NEVER DO IT if you are not already synced with the last block)

Create your validator if you are not synced, you will get some troubles...

gravity tx staking create-validator \
 --amount=1000000ugraviton \
 --pubkey=$(gravity tendermint show-validator) \
 --moniker="YOUR_NICKNAME" \
 --chain-id=gravity-bridge-3 \
 --commission-rate=0.05 \
 --commission-max-rate=0.2 \
