StacksPack Build Krypton-1

Today's release includes updates to the Stacks Blockchain software that enable Proof of Transfer (PoX)!

Updates include:

  • updated Stacks Blockchain tools
  • runs on the Krypton testnet
  • enables mining and Proof of Transfer consensus

Known Issues:

If you have issues burning the zip image, feel free to unzip and burn the image file directly. Ubuntu's Startup Disk Creator works with the img file. So does dd. YMMV.

Notes

  • Burn the image with your favorite tool.
  • Insert into your Raspberry Pi 3B or later
  • Default username: stacks
  • Default password: NewInternet
  • SSH is enabled by default
  • The 'lite' image does not have a graphical desktop. If you'd like that, use the standard StacksPack image.

Requirements:

  • 4 GB or larger SD card. 8 GB recommend. If you get a cheap one, you'll regret it later.
  • 500 GB or larger external hard drive. 1 TB recommended.
  • Wired Ethernet or WiFi with DHCP enabled. Wired connection recommended.

Getting Started

If you're using the full desktop version, enter these commands in a terminal.

1. Log into your StacksPack miner via keyboard or ssh. Default username is 'stacks' and default password is 'NewInternet'

2. Change the default password.

passwd

Follow the prompts.

3. Set up wifi (optional)

sudo raspi-config

Follow the prompts.

* '2. Network Options'

* N2 Wireless Lan

* Select your country

* Enter your SSID (wifi network name)

* Enter your wifi password

* Finish

Reboot and log in with your updated password, from step 2

4. Mount your external drive and make a mining folder. Your drive may already be mounted automagically as a media device for the user, but we want to put it in a deterministic spot for the miner.

sudo umount /dev/sda1

sudo mount /dev/sda1 /mnt

sudo mkdir /mnt/stacks

Kewl.

5. Install utilities

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.36.0/install.sh | bash

export NVM_DIR="$HOME/.nvm"

[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm

[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion

nvm install node

npm install -g stacks-gen

sudo apt install jq -y

Setting up your miner

6. Generate a testnet keychain

stacks-gen sk --testnet > keychain.json

7. Request testnet bitcoin for our miner.

curl -sS -X POST https://stacks-node-api.krypton.blockstack.org/extended/v1/faucets/btc\?address\="$(tail -n +2 keychain.json | jq -r '.btc')"

8. Add our private key to the miner config

sudo sed -i "s/replace-with-your-private-key/$(tail -n +2 keychain.json | jq -r '.private')/g" /etc/stacks-blockchain/krypton-miner-conf.toml

9. Test the miner

sudo /usr/local/bin/stacks-node start --config=/etc/stacks-blockchain/krypton-miner-conf.toml

You should see something like this:

==> /etc/stacks-blockchain/krypton-miner-conf.toml
INFO [1601279939.478] [testnet/stacks-node/src/run_loop/neon.rs:99] [ThreadId(1)] Miner node: checking UTXOs at address: mkDwdSRMyfmZYvUndZdjXP56kW4yoUeCGS
INFO [1601279941.996] [testnet/stacks-node/src/run_loop/neon.rs:107] [ThreadId(1)] Miner node: starting up, UTXOs found.

If you see any errors, please report them here: https://gitlab.com/riot.ai/stackspack/-/issues/new. If not, `ctrl-c` and we'll continue.

10. Enable our miner to run as a system service

sudo systemctl enable stacks-node.service

11. Start our miner

sudo systemctl start stacks-node.service

12. Congratulations! You're helping to test the stacks testnet! We love ❤️ you for that.

To view logs at any time, open a terminal and type sudo journalctl -u stacks-node
