Install

Requirements: go installed and set up (version 1.10+).

0. If installing from a new Ubuntu server (16.04 or 18.04), here's how to setup go:

   sudo apt update
   sudo apt upgrade -y
   sudo apt install git gcc make wget -y
   wget https://dl.google.com/go/go1.10.3.linux-amd64.tar.gz
   sudo tar -xvf go1.10.3.linux-amd64.tar.gz
   sudo mv go /usr/local
   
   cat >> ~/.profile <<EOF
   export GOROOT=/usr/local/go
   export GOPATH=\$HOME/go
   export PATH=\$GOPATH/bin:\$GOROOT/bin:\$PATH
   EOF
   
   source ~/.profile
   

1. Get the code.

   mkdir -p $GOPATH/src/github.com/kava-labs
   cd $GOPATH/src/github.com/kava-labs
   git clone https://github.com/kava-labs/kava
   cd kava
   git checkout 8c9406c
   

2. Install the dependencies.

   mkdir $GOPATH/bin
   curl https://raw.githubusercontent.com/golang/dep/master/install.sh | sh
   dep ensure
   

3. Install the code

    go install ./cmd/kvd
    go install ./cmd/kvcli
   

Run a Full Node

kvd init --name <your-name> --chain-id kava-test-2

This will generate config and keys in $HOME/.kvd and $HOME/.kvcli. The default password is 'password'.

Note: Make sure GOBIN is set and added to your path if you want to be able to run installed go programs from any folder.

Copy the testnet genesis file (from https://raw.githubusercontent.com/Kava-Labs/kava/master/testnets/kava-test-2/genesis.json) into $HOME/.kvd/config/, replacing the existing one.

Add the kava node address, 5c2bc5a95b014e4b2897791565398ee6bfd0a04a@validator.connector.kava.io:26656, to seeds in $HOME/.kvd/config/config.toml

Start your full node

kvd start

Or, to start in background and send to log:

kvd start &> kvd.log &

To see the output of the log:

tail -f kvd.log

Note: It might take a while to fully sync. Check the latest block height here.

Run a Validator

Join the validator chat. Follow setup for a full node above.

Get you address with kvcli keys list. Should look something like cosmosaccaddr10jpp289accvkhsvrpz4tlj9zhqdaey2tl9m4rg.

Ask @rhuairahrighairidh in the chat to give you some coins.

Get your validator pubkey with kvd tendermint show_validator

Then, your full running in the background or separate window, run:

kvcli stake create-validator \
        --amount 900KVA \
        --pubkey <you validator pubkey from above> \
        --address-validator <your address from above> \
        --moniker "<your name>" \
        --chain-id kava-test-2 \
        --from <your name> \
        --gas 1000000

Note You'll need to type in the default password "password"

Now your full node should be participating in consensus and validating blocks!

Running a validator requires that you keep validating blocks. If you stop, your stake will be slashed.
In order to stop validating, first remove yourself as validator, then you can stop your node.

kvcli stake unbond begin \
    --address-delegator <your address> \
    --address-validator <your address> \
    --chain-id kava-test-2 \
    --shares-percent 1 \
    --from <your name> \
    --gas 1000000
