Install the SDK

This guide will explain how to install the Cosmos SDK onto your system. With the SDK installed on a server, you can participate in the latest testnet as either a Full Node or a Validator.

Install Go

Install go by following the official docs. Remember to set your $GOPATH, $GOBIN, and $PATH environment variables, for example:

mkdir -p $HOME/go/bin
echo "export GOPATH=$HOME/go" >> ~/.bash_profile
echo "export GOBIN=$GOPATH/bin" >> ~/.bash_profile
echo "export PATH=$PATH:$GOBIN" >> ~/.bash_profile

::: tip Go 1.10+ is required for the Cosmos SDK. :::

Install Cosmos SDK

Next, let's install the testnet's version of the Cosmos SDK. You can find information about the latest testnet and the right version of the Cosmos-SDK for it in the testnets repo. Here we'll use the master branch, which contains the latest stable release. If necessary, make sure you git checkout the correct released version.

mkdir -p $GOPATH/src/github.com/cosmos
cd $GOPATH/src/github.com/cosmos
git clone https://github.com/cosmos/cosmos-sdk
cd cosmos-sdk && git checkout master
make get_tools && make get_vendor_deps && make install

That will install the gaiad and gaiacli binaries. Verify that everything is OK:

$ gaiad version
$ gaiacli version

Run a Full Node

With Cosmos SDK installed, you can run a full node on the latest testnet.
