  • 200GB - 300GB Disk space per year

Software Requirements

Install deps

Compile instructions: install GoLang

Install Go 1.16.x The official instructions can be found here: https://golang.org/doc/install

First remove any existing old Go installation as root

sudo rm -rf /usr/local/go

Download the software:

curl https://dl.google.com/go/go1.16.8.linux-amd64.tar.gz | sudo tar -C/usr/local -zxvf -

Update environment variables to include go (copy everything and paste)

cat <<'EOF' >>$HOME/.profile
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GO111MODULE=on
export GOBIN=$HOME/go/bin
export PATH=$PATH:/usr/local/go/bin:$GOBIN
EOF
source $HOME/.profile

To verify that Go is installed:

go version

Should return go version go1.16.8 linux/amd64

Compile BCNAD source code by yourself

Download source code and compile

git clone https://github.com/BitCannaGlobal/bcna.git
cd bcna
git checkout v1.2
make build   #it build the binary in build/ folder

To know the version:

build/bcnad version

The output must be 1.2

Is the versión match, now you have two options

  • Move the binary to the /usr/local/bin path with: sudo mv build/bcnad /usr/local/bin/
  • Compile and install the binary in the $GOPATH path: make install
  • If you are using Cosmovisor you need to perform extra steps to move the binary to the proper Cosmovisor folder.

Cosmosvisor Quick Start

Cosmovisor is a small process manager for Cosmos SDK binaries that monitors the governance module via stdout for incoming chain upgrade proposals. If it sees a proposal that gets approved, it can be run manually or automatically to download the new binary, stop the current binary, run the migration script, replace the old node binary with the new one, and finally restart the node with the new genesis file.

Installation

To install cosmovisor, run the following command (it takes some minutes):

go get github.com/cosmos/cosmos-sdk/cosmovisor/cmd/cosmovisor
