|
|
|
|
A decentralized fast-finality blockchain for interoperable payment channel networks.
|
|
Building on the work of Tendermint and Interledger.
|
|
|
|
Project status: We're currently in a very early public testnet. With future features being implemented.
|
|
|
|
Try it out - run a full node to sync to the testnet, or set up as a validator.
|
|
|
|
|
|
|
|
## Install
|
|
|
|
<!--### Source-->
|
|
|
|
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
|
|
|
|
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
|
|
|
|
<!--### Docker
|
|
|
|
Requirements: docker installed.
|
|
|
|
No installation necessary, just prepend commands with `docker run kava/kava`. TODO name necessary to avoid new contianer being created each time?
|
|
|
|
This will use our docker container `kava/kava` and store all blockchain data and keys within the container. -->
|
|
|
|
<!-- To store this data outisde the conatiner, attach volumes to the container:
|
|
|
|
docker run --rm -v $HOME/.kvd:/root/.kvd -v $HOME/.kvcli:/root/.kvcli kava/kava <further commands>
|
|
|
|
Now blockchain data will be stored in `$HOME/.kvd` and keys in `$HOME/.kvcli`. Also the `--rm` flag removes the contianer after each run.
|
|
|
|
-->
|
|
<!-- ## Send Transactions
|
|
|
|
You can send transactions on the testnet using our node without yncing a local node.
|
|
Requirements
|
|
|
|
TODO users need to set up keys first?
|
|
|
|
kvcli <args> --node validator.connector.kava.io:26657 --chain-id kava-test-<current version>
|
|
-->
|
|
|
|
## Run a Full Node
|
|
|
|
kvd init --name <your-name> --chain-id kava-test-2
|
|
|
|
This will generate config and keys in `$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
|
|
|
|
> Note: It might take a while to fully sync. Check the latest block height [here](http://validator.connector.kava.io:26657/abci_info).
|
|
|
|
|
|
## Run a Validator
|
|
Join the [validator chat](https://riot.im/app/#/room/#kava-validators:matrix.org). 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>
|
|
> 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>
|
