The first step of the KiChain testnet challenge is to initiate a new testnet from scratch. Therefore, participants are required to create the keys of their validators and to generate their genesis transactions.

Following are the System requirements to run a node on the KiChain testnet:

  • Ubuntu 18.04 OS or later
  • 4 Cores
  • 4GB RAM
  • 80GB SSD at least

Following is the process of creating the validator keys and the genesis transaction:

Download and install Go v1.13.5+ )

wget https://dl.google.com/go/go1.13.5.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.13.5.linux-amd64.tar.gz

Export Go paths

GOPATH=/usr/local/go
PATH=$GOPATH/bin:$PATH
mkdir -p $HOME/go/bin
echo "export PATH=$PATH:$(go env GOPATH)/bin" >> ~/.bash_profile
source ~/.bash_profile

Test the installation

go version

Clone and install ki-tools

git clone https://github.com/KiFoundation/ki-tools.git
cd ki-tools
git checkout testnet
make install

Check the installed version

kid version --long

This should ouput

name: ki-tools
server_name: kid
client_name: kicli
version: 0.1-13-g711e19e-Testnet
commit: 711e19ebbb516ae6d38c638634c4bef05201be72
build_tags: netgo,ledger
go: go version go1.13.5 linux/amd64

Create node directories:

export NODE_ROOT= <location of your choice>
mkdir -p $NODE_ROOT/kid $NODE_ROOT/kicli $NODE_ROOT/kilogs
cd $NODE_ROOT

Initiate the node files

kid init <your-validator-moniker> --chain-id kichain-t-2 --home ./kid/

Create the validator account. Do not forget to save the mnemonic.

kicli keys add <wallet-name> --home ./kicli/

Feed the validator wallet with 100tki

kid add-genesis-account $(kicli keys show <wallet-name> -a --home kicli/ ) 100000000utki --home kid/

Generate the genesis transaction for the validator creation

kid gentx \
	--commission-max-change-rate=0.1 \
	--commission-max-rate=0.1 \
	--commission-rate=0.1 \
	--min-self-delegation=1 \
	--amount=100000000utki \
	--pubkey `kid tendermint show-validator --home ./kid/` \
	--name=<wallet-name> \
	--home ./kid/ \
	--home-client ./kicli/

this generates a file called gentx-<node-id>.json in $NODE_ROOT/kid/config/gentx/. Run the following commands to fetch the validator addresses needed to fill the registration form.

(The following step requires jq. It can be installed with sudo apt-get install jq. You can skip installing jq and manually fetch the information below in the file).

Validator testnet wallet address:

cat $NODE_ROOT/kid/config/gentx/gentx-<node-id>.json | jq .value.msg[0].value.delegator_address

Validator testnet operator address:

cat $NODE_ROOT/kid/config/gentx/gentx-<node-id>.json | jq .value.msg[0].value.validator_address
