DXOS Naming Service

The DXOS Naming Service (DXNS) is a custom blockchain built using Cosmos SDK.

Getting Started

Installation

• Install golang 1.14.0+ for the required platform.
• Ensure that the version installed is older than 1.16 as crypto/hmac panics while using dxnscli in newer versions.
• Test that the correct version of golang has been successfully installed on the machine.

$ go version
go version go1.14.9 darwin/amd64

Set the following ENV variables (if go mod has never been used on the machine).

mkdir -p $HOME/go/bin
echo "export GOPATH=$HOME/go" >> ~/.profile
echo "export GOBIN=\$GOPATH/bin" >> ~/.profile
echo "export PATH=\$PATH:\$GOBIN" >> ~/.profile
echo "export GO111MODULE=on" >> ~/.profile
source ~/.profile

Clone the repo then build and install the binaries.

$ git clone git@github.com:vulcanize/dxns.git
$ cd dxns
$ make install

Test that the following commands work:

$ dxnsd help
$ dxnscli help
