This testnet is using a custom version of cosmos-sdk in which the sync bug from gaia-7001 is fixed.

These instructions are for setting up a brand new full node from scratch. If you ran a full node on a previous testnet you will need to start from scratch due to some breaking changes in key format.

Install go by following the official docs. Go 1.10+ is required for the Cosmos SDK. Remember to properly setup your $GOPATH, $GOBIN, and $PATH 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

Next, let's install the testnet's version of the Cosmos SDK.

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 c01a3d218f2544b00b817942e996e171c397b2a4
make get_tools && make get_vendor_deps && make install

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

$ gaiad version
0.22.0-c01a3d2
