Terra is a public, open-source blockchain protocol that provides fundamental infrastructure for a decentralized economy and enables open participation in the creation of new financial primitives to power the innovation of money.

Classic is the reference implementation of the Terra protocol, written in Golang. Terra Core is built atop Cosmos SDK and uses Tendermint BFT consensus. If you intend to work on Terra Core source, it is recommended that you familiarize yourself with the concepts in those projects.

Upon the implosion of Terra, a group of rebels seized control of the blockchain. Terra's future is uncertain, but the rebels are now firmly in control.

The easiest way to get started is by downloading a pre-built binary for your operating system. You can find the latest binaries on the releases page.

Step 1. Install Golang

Go v1.19+ or higher is required for Terra Core.

If you haven't already, install Golang by following the official docs. Make sure that your GOPATH and GOBIN environment variables are properly set up.

Step 2: Get Terra Core source code

Use git to retrieve Terra Core from the official repo and checkout the main branch. This branch contains the latest stable release, which will install the terrad binary.

git clone https://github.com/terra-money/core/
cd core
git checkout main

Step 3: Build Terra core

Run the following command to install the executable terrad to your GOPATH and build Terra Core. terrad is the node daemon and CLI for interacting with a Terra node.

# COSMOS_BUILD_OPTIONS=rocksdb make install
make install

Step 4: Verify your installation

Verify that you've installed terrad successfully by running the following command:

terrad version --long

If terrad is installed correctly, the following information is returned:

name: terra
server_name: terrad
version: 0.5.0-rc0-9-g640fd0ed
commit: 640fd0ed921d029f4d1c3d88435bd5dbd67d14cd
build_tags: netgo,ledger
go: go version go1.17.2 darwin/amd64

NOTE: terracli has been deprecated and all of its functionalities have been merged into terrad.

terrad is the all-in-one command for operating and interacting with a running Terra node. For comprehensive coverage on each of the available functions, see the terrad reference information. To view various subcommands and their expected arguments, use the $ terrad --help command:

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

The following requirements are recommended for running a columbus-5 mainnet node:

• 4 or more CPU cores
• At least 2TB of disk storage
• At least 100mbps network bandwidth
• An Linux distribution
