What is initia?

initia is a public, open-source, proof-of-stake blockchain. The initia is the cosmos implementation of the MoveVM written in Golang. The initia is powered by the Cosmos SDK and Tendermint BFT consensus.

Installation

From Binary

The easiest way to install the initia is to download a pre-built binary. You can find the latest binaries on the releases page.

From Source

Step 1: Install Golang

Go v1.19+ or higher is required for The initia.

  1. Install Go 1.19+ from the official site. Ensure that your GOPATH and GOBIN environment variables are properly set up by using the following commands:

    For Windows:

    wget <https://golang.org/dl/go1.19.1.linux-amd64.tar.gz>
sudo tar -C /usr/local -xzf go1.19.1.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin
export PATH=$PATH:$(go env GOPATH)/bin

    For Mac:

    export PATH=$PATH:/usr/local/go/bin
export PATH=$PATH:$(go env GOPATH)/bin

  2. Confirm your Go installation by checking the version:

    go version

Step 2: Get initia source code

Clone the initia from the official repo and check out the main branch for the latest stable release.

git clone https://github.com/initia-labs/initia/
cd initia
git checkout main

Step 3: Build initia

Run the following command to install initiad to your GOPATH and build the initia. initiad is the node daemon and CLI for interacting with a initia node.

# COSMOS_BUILD_OPTIONS=rocksdb make install
make install

Step 4: Verify your installation

Verify your installation with the following command:

initiad version --long

A successful installation will return the following:

name: initia
server_name: initiad
version: <x.x.x>
commit: <Commit hash>
build_tags: netgo,ledger
go: go version go1.18.2 darwin/amd64

initiad

initiad is the all-in-one CLI and node daemon for interacting with the initia blockchain.

Node Setup

Once you have initiad installed, you will need to set up your node to be part of the network.

Join the mainnet

The following requirements are recommended for running a mainnet node:

  • Four or more CPU cores
  • At least 32 GB of memory
  • At least 300 mbps of network bandwidth
  • At least 2 TB NVME SSD
  • A Linux distribution

initia node quickstart

initiad init nodename
wget -O ~/.initia/config/genesis.json https://cloudflare-ipfs.com/ipfs/QmZAMcdu85Qr8saFuNpL9VaxVqqLGWNAs72RVFhchL9jWs
curl https://network.initia.co/addrbook.json > ~/.initiad/config/addrbook.json
initiad start

Join a testnet

Several testnets might exist simultaneously. Ensure that your version of initiad is compatible with the network you want to join.

To set up a node on the latest testnet, visit the testnet repo.

Run a local testnet

The easiest way to set up a local testing environment is to run Localinitia, a zero-configuration complete testing environment.

Run a single node testnet

You can also run a local testnet using a single node. On a local testnet, you will be the sole validator signing blocks.

Step 1: Create network and account

First, initialize your genesis file to bootstrap your network. Create a name for your local testnet and provide a moniker to refer to your node:

initiad init --chain-id=<testnet_name> <node_moniker>

Next, create a initia account by running the following command:

initiad keys add <account_name>

Step 2: Add account to genesis

Add your account to genesis and set an initial balance to start. Run the following commands to add your account and set the initial balance:

initiad add-genesis-account $(initiad keys show <account_name> -a) 100000000uini
initiad gentx <account_name> 10000000uini --chain-id=<testnet_name>
initiad collect-gentxs

Step 3: Run initiad

Now you can start your private initia network:

initiad start

Your initiad node will be running a node on tcp://localhost:26656, listening for incoming transactions and signing blocks.

Set up a production environment

Note: This guide only covers general settings for a production-level full node. Visit the initia validator's guide for more information.

This guide has been tested against Linux distributions only. To ensure you successfully set up your production environment, consider setting it up on an Linux system.

Increase maximum open files

By default, initiad can't open more than 1024 files at once.

You can increase this limit by modifying /etc/security/limits.conf and raising the nofile capability.

*                soft    nofile          65535
*                hard    nofile          65535

Create a dedicated user

It is recommended that you run initiad as a normal user. Super-user accounts are only recommended during setup to create and modify files.

Port configuration

initiad uses several TCP ports for different purposes.

  • 26656: The default port for the P2P protocol. Use this port to communicate with other nodes. While this port must be open to join a network, it does not have to be open to the public. Validator nodes should configure persistent_peers and close this port to the public.

  • 26657: The default port for the RPC protocol. This port is used for querying / sending transactions and must be open to serve queries from initiad. DO NOT open this port to the public unless you are planning to run a public node.

  • 1317: The default port for Lite Client Daemon (LCD), which can be enabled in ~/.initia/config/app.toml. The LCD provides an HTTP RESTful API layer to allow applications and services to interact with your initiad instance through RPC. Check the initia REST API for usage examples. Don't open this port unless you need to use the LCD.

  • 26660: The default port for interacting with the Prometheus database. You can use Promethues to monitor an environment. This port is closed by default.

Run the server as a daemon

Important:

Keep initiad running at all times. The simplest solution is to register initiad as a systemd service so that it automatically starts after system reboots and other events.

Register initiad as a service

First, create a service definition file in /etc/systemd/system.

Sample file: /etc/systemd/system/initiad.service

[Unit]
Description=initia Daemon
After=network.target

[Service]
Type=simple
User=terra
ExecStart=/data/terra/go/bin/initiad start
Restart=on-abort

[Install]
WantedBy=multi-user.target

[Service]
LimitNOFILE=65535

Modify the Service section from the given sample above to suit your settings. Note that even if you raised the number of open files for a process, you still need to include LimitNOFILE.

After creating a service definition file, you should execute systemctl daemon-reload.

Start, stop, or restart service

Use systemctl to control (start, stop, restart)

# Start
systemctl start initiad
# Stop
systemctl stop initiad
# Restart
systemctl restart initiad

Access logs

# Entire log
journalctl -t initiad
# Entire log reversed
journalctl -t initiad -r
# Latest and continuous
journalctl -t initiad -f
