Deploy a Testnet

Software Setup Manual Installation

• Install GNU Wget:

MacOS

brew install wget

Linux

sudo apt-get install wget

Note: You can check other available options for downloading wget here.

Get Source Code

go get github.com/cosmos/cosmos-sdk

Now we can fetch the correct versions of each dependency by running:

cd $GOPATH/src/github.com/cosmos/cosmos-sdk
git fetch --all
git checkout 0f2aa6b
make get_tools // run $ make update_tools if already installed
make get_vendor_deps
make install

The latest binaries should now be installed. Verify that everything is OK by running:

gaiad version

You should see:

0.15.0-rc0-0f2aa6b

And also:

gaiacli version

You should see:

0.15.0-rc0-0f2aa6b

Genesis Setup

Initiliaze gaiad :

gaiad init

You can find the corresponding genesis files here. Then replace the genesis.jsonand config.toml files:

rm $HOME/.gaiad/config/genesis.json $HOME/.gaiad/config/config.toml $HOME/.gaiad/config/addrbook.json

wget -O $HOME/.gaiad/config/genesis.json https://raw.githubusercontent.com/cosmos/testnet/master/gaia-4000/genesis.json

wget -O $HOME/.gaiad/config/config.toml https://raw.githubusercontent.com/cosmos/testnet/master/gaia-4000/config.toml

Lastly change the moniker string in theconfig.tomlto identify your node.

# A custom human readable name for this node
moniker = "<your_custom_name>"

Starting Gaiad

Start the full node:

gaiad start

Check the everything is running smoothly:

gaiacli status

Generate keys

You'll need a private and public key pair a.k.a. `sk, pk` respectively to be able to receive funds, send txs, bond tx, etc.

To generate your a new key default _ed25519_ elliptic curve:

gaiacli keys add default

Next, you will have to enter a passphrase for your key twice. Save the seed phrase in a safe place in case you forget the password.

Now if you check your private keys you will see the key among them:

gaiacli keys list

Getting Coins

Go to the faucet in http://atomexplorer.com/ and claim some coins for your testnet by typing the address of your key, as printed out above.

Send tokens

gaiacli send --amount=1000fermion --chain-id=gaia-4000 --sequence=0 --name=default --to=<destination_address>

The --amount flag defines the corresponding amount of the coin in the format --amount=<value|coin_name>

The --sequence flag corresponds to the sequence number to sign the tx.

Now check the destination account and your own account to check the updated balances by default the latest block:

gaiacli account <destination_address>
gaiacli account <your_address>

Staking: Becoming a Validator

Get your public key by typing:

gaiad show_validator

Take the base64 encoded string from the value field and use this to convert it to hex. Change Group by to None.

Send the bonding transaction:

Remember to use your own validator address or use mine if you want to delegate to me.

gaiacli bond --stake=6steak --validator=45798afe9b0cd7a05b765107b744478f91848d18a54ce7d06daace1c71a56913 --sequence=0 --chain-id=gaia-4000 --name=default
