Stratos block testnet genesis and config.

The latest version is v0.10.0, with a new chain-id mesos-1.

To create a separated and more secure environment, it is recommended to create a separated user account to run node.

sudo adduser stratos --home /home/stratos 

Once user is created, login the system using stratos account and proceed with installation steps in context of that user

cd $HOME wget https://github.com/stratosnet/stratos-chain/releases/download/v0.10.0/stchaind

These binary files are built using linux amd64, so if you prefer to run a node on a different kernel, please follow step 1.1 to build binaries.

For ease of use, we recommend you save these files in your $HOME folder. In the following, we suppose you are in the $HOME folder.

• Check the granularity

# Check granularity md5sum stchain* ## Expected output ## e7e52a3831f8c22864badbf4c268adb5 stchaind

• Add execute permission to the binary downloaded

chmod +x stchaind

Make sure you have Go 1.19+ installed (link).

 git clone https://github.com/stratosnet/stratos-chain.git cd stratos-chain git checkout tags/v0.10.0 make build

The binary file stchaind can be found in build folder. Then, move these two binary files to $HOME

mv build/stchaind ./

make install

./stchaind init "<node name you prefer>" # ignore the output since you need to download the genesis file 

wget https://raw.githubusercontent.com/stratosnet/stratos-chain-testnet/main/genesis.json wget https://raw.githubusercontent.com/stratosnet/stratos-chain-testnet/main/config.toml

In config.toml file, at Line #16, there is a “moniker” field. Change it to any name you like. It’s your node name on the network.

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

mv config.toml .stchaind/config/ mv genesis.json .stchaind/config/

By default, the two binary executable files stchaind as well as the directory .stchaind have been saved or created in the $HOME folder. The .stchaind folder contains the node's configurations and data.

There are three ways to run your Stratos-chain full-node. Please choose ONE of them to start the node.

• stchaind start command

  # Make sure we are inside the home directory cd $HOME # run your node ./stchaind start # Use `Ctrl+c` to stop the node.

• Run node in background

  # Make sure we are inside the home directory cd $HOME # run your node in backend ./stchaind start 2>&1 >> chain.log & 

  Use an editor to check your node log at chain.log

  Use the following Linux Command to stop your node.

  pkill stchaind

• Run node as a service

  All below steps require root privileges

  • Create the service file Create the /lib/systemd/system/stratos.service file with the following content

    [Unit] Description=Stratos Chain Node After=network-online.target [Service] User=stratos ExecStart=/home/stratos/stchaind start --home=/home/stratos/.stchaind Restart=on-failure RestartSec=3 LimitNOFILE=8192 [Install] WantedBy=multi-user.target

    In the [service] section

    • User is your system login username
    • ExecStart designates the absolute path to the binary executable stchaind
    • --home is the absolute path to your node folder.
    • We used the default values for these variables. If you use a different username, group or folder to hold your node data instead of the default values, please modify these values according to your situations. Make sure the above values are correct.

  • Start your service Once you have successfully created the service, you need to enable and start it by running

    systemctl daemon-reload systemctl enable stratos.service systemctl start stratos.service

  • Service operations

    • Check the service status

      systemctl status stratos.service

    • Check service log

      journalctl -u stratos.service -f # exit with ctrl+c

    • Stop the service

      systemctl stop stratos.service

Once the node finishes catching-up, you can operate the node for various transactions(tx) and queries.

In the following, we list some of commonly-used operations. More details and examples can be found here.

./stchaind keys add --hd-path "m/44'/606'/0'/0/0" --keyring-backend test <your wallet name>

Example

./stchaind keys add --hd-path "m/44'/606'/0'/0/0" --keyring-backend test wallet1

After executed the above command, a .stchaind will be created in your $HOME folder.

Faucet will be available at https://faucet-mesos.thestratos.org/ to get test tokens

curl --header "Content-Type: application/json" --request POST --data '{"denom":"stos","address":"your wallet address"} ' https://faucet-mesos.thestratos.org/credit

Check balance (you need to wait for your node catching up with the network)

./stchaind query account <your wallet address>

Check node status

./stchaind status

./stchaind tx send <from account address | name> <to address> <amount> --keyring-backend=<keyring's backend> --chain-id=<current chain-id> --gas=<gas amount> --gas-prices=<gas-price>

./stchaind tx bank send user0 st1sqzsk8mplv5248gx6dddzzxweqvew8rtst96fx 1gwei --chain-id=mesos-1 --keyring-backend=test --gas=auto --gas-prices=10000000wei # then input y for the pop up to confirm send

• In testing phase, --keyring-backend="test"
• In testing phase, chain-id may change when updating, which can be found on this page, right next to the search bar at the top of the page. The current chain-id is mesos-1.

After the following steps have been done, Any participant in the network can signal that they want to become a validator. Please refer to How to Become a Validator for more details about validator creation, delegation as well as FAQ.

• download related files
• start your node to catch up to the latest block height(synchronization)
• create your Stratos Chain Wallet
• Faucet or send an amount of tokens to this wallet
