Join Injective Mainnet

Hardware Specification​

Node operators should expect to provision one or more data center locations with redundant power, networking, firewalls, HSMs and servers.

The minimum hardware specifications are as follows, though they might rise as network usage increases:

(AWS r6i.2xlarge Instance)
8+ vCPU x64
64+ GB RAM
1+ TB SSD storage
1+ Gbps Network Bandwidth

For a more performant node, the following configuration is recommended:

(AWS r6i.4xlarge Instance or higher)
16+ vCPU
128+ GB RAM
2+ TB SSD storage
5+ Gbps Network Bandwidth

The more storage allocated, the less frequently data must be pruned from the node.

Install injectived and peggo​

See the Injective chain releases repo for the most recent releases. Non-validator node operators do not need to install peggo.

wget https://github.com/InjectiveLabs/injective-chain-releases/releases/download/v1.12.1-1705909076//linux-amd64.zip
unzip linux-amd64.zip
sudo mv peggo /usr/bin
sudo mv injectived /usr/bin
sudo mv libwasmvm.x86_64.so /usr/lib

Initialize a New Injective Chain Node​

Before running the Injective Chain node, we need to initialize the chain as well as the node's genesis file:

# The argument <moniker> is the custom username of your node. It should be human-readable.
export MONIKER=<moniker>
# Injective Mainnet has a chain-id of "injective-1"
injectived init $MONIKER --chain-id injective-1

Running the init command will create injectived default configuration files at ~/.injectived.

Prepare Configuration to Join Mainnet​

You should now update the default configuration with the Mainnet's genesis file and application config file, as well as configure your persistent peers with seed nodes.

git clone https://github.com/InjectiveLabs/mainnet-config

# copy genesis file to config directory
cp mainnet-config/10001/genesis.json ~/.injectived/config/genesis.json

# copy config file to config directory
cp mainnet-config/10001/app.toml  ~/.injectived/config/app.toml

You can also run verify the checksum of the genesis checksum - 573b89727e42b41d43156cd6605c0c8ad4a1ce16d9aad1e1604b02864015d528

sha256sum ~/.injectived/config/genesis.json

Then update the seeds field in ~/.injectived/config/config.toml with the contents of mainnet-config/10001/seeds.txt and update the timeout_commit to 300ms.

cat mainnet-config/10001/seeds.txt
nano ~/.injectived/config/config.toml

Configure systemd Service for injectived​

Edit the config at /etc/systemd/system/injectived.service:

[Unit]
  Description=injectived

[Service]
  WorkingDirectory=/usr/bin
  ExecStart=/bin/bash -c '/usr/bin/injectived --log-level=error start'
  Type=simple
  Restart=always
  RestartSec=5
  User=root

[Install]
  WantedBy=multi-user.target

Starting and restarting the systemd service:

sudo systemctl daemon-reload
sudo systemctl restart injectived
sudo systemctl status injectived

# enable start on system boot
sudo systemctl enable injectived

# To check Logs
journalctl -u injectived -f

The service should be stopped before and started after the snapshot data has been loaded into the correct directory.

# to stop the node
sudo systemctl stop injectived

# to start the node
sudo systemctl start injectived

Sync with the network​

Option 1. State-Sync​

To be added soon

Option 2. Snapshots​

Pruned

  1. Polkachu.
  2. HighStakes.
  3. AutoStake.
  4. Imperator.
  5. Bware Labs.

Alternatively, you can use the pruned snapshots from Injective Labs on AWS S3.

systemctl stop injectived
injectived tendermint unsafe-reset-all --home $HOME/.injectived
SNAP=$(aws s3 ls s3://injective-snapshots/mainnet/pruned/ | grep ".tar.lz4" | sort | tail -n 1 | awk '{print $4}')
aws s3 cp s3://injective-snapshots/mainnet/pruned/$SNAP .
lz4 -c -d $SNAP  | tar -x -C $HOME/.injectived/
rm $SNAP
systemctl start injectived

Should the Injective mainnet-config seeds.txt list not work (the node fails to sync blocks), ChainLayer, Polkachu, and Autostake maintain peer lists (can be used in the persistent_peers field in config.toml) or addressbooks (for faster peer discovery).

Archival (>20TB)

systemctl stop injectived
injectived tendermint unsafe-reset-all --home $HOME/.injectived
aws s3 sync --no-sign-request --delete s3://injective-snapshots/mainnet/injectived/data $HOME/.injectived/data
aws s3 sync --no-sign-request --delete s3://injective-snapshots/mainnet/injectived/wasm $HOME/.injectived/wasm
systemctl start injectived

At this point, GEX can be used to monitor the node's sync status. If the snapshot has been correcly loaded, the number of connected peers should increase from 0 and the latest block should steadily increase, signalling the node syncing with its peers. Note that it may take a few or several hours for the node to catch up to the network's block height depending on the age of the snapshot.

In the case where the latest block does not increase and the number of connected peers is 0 or remains low, the seed list in seeds.txt may be outdated, and the seeds or persistent_peers fields can be updated using a validator's seed or peer list respectively, before the node is started again.
