Zeitgeist | 0.3.X

⠀Zeitgeist is an evolving network that will change and adapt over time. It uses prediction markets based futarchy to determine its direction and policy.

Information about the project

Description

⠀Zeitgeist is not only building a platform, but also an ecosystem for prediction markets. Team is creating a community where participants can have a voice in how the protocol changes over time. This is enabled particularly by a set of primitives built for a court system, and leverages a robust on-chain upgradable governance system. Researchers will be able to propose new ideas, traders can discuss and request new markets, developers can build on the open protocol, and entrepreneurs have the freedom to create their application that targets a niche vertical market.

Testnet phases

⠀The phase is still unknown, the «Zeitgeist node v0.2.0» testnet has just begun.

Rewards

⠀Yes, we plan to reward node operators. We will definitely have some form of rewards for collators and we are discussing additional options. A set of node operators who have run a node during the previous months will be the first one eligble to be collators. We will announce some more detailed information in the near future.

Launching

To the content

⠀Each subsection is a separate type of installation, you have to select one of them.

Linux (manual)

For beginners

⠀Update packages

sudo apt update && sudo apt upgrade -y

⠀Install dependencies

sudo apt install wget jq build-essential pkg-config libssl-dev -y

⠀Create a user

sudo useradd -M zeitgeist
sudo usermod zeitgeist -s /sbin/nologin

⠀Create a folder for a node

sudo mkdir -p /services/zeitgeist/bin /services/zeitgeist/battery_station

⠀Download appropriate files

cd; \

cp /services/zeitgeist/bin/zeitgeist /usr/bin/

⠀Assign the folder owner

sudo chown -R zeitgeist:zeitgeist /services/zeitgeist

⠀Come up with a name for a node, run a command and enter a name, thereby adding it to the system as a variable

. <(wget -qO- https://raw.githubusercontent.com/SecorD0/utils/main/miscellaneous/insert_variable.sh) -n zeitgeist_moniker

⠀Open used ports

. <(wget -qO- https://raw.githubusercontent.com/SecorD0/utils/main/miscellaneous/ports_opening.sh) 30333 9933 9944 30334 9934 9945

⠀Create a service file

sudo tee <<EOF >/dev/null /etc/systemd/system/zeitgeistd.service

sudo systemctl restart zeitgeistd

⠀Add a command to view the log of a node in the system as a variable

. <(wget -qO- https://raw.githubusercontent.com/SecorD0/utils/main/miscellaneous/insert_variable.sh) -n zeitgeist_log -v "sudo journalctl -f -n 100 -u zeitgeistd" -a

⠀Save the file in a safe place (the command displays the path)

echo /services/zeitgeist/battery_station/chains/battery_station_mainnet/network/secret_ed25519

If you participated in earlier stages of the project

⠀Go to the «Recovery» section.

If you run this node for the first time

⠀Run container

docker run -dit \
    -v $HOME/.zeitgeist:/zeitgeist/data \
    -u $(id -u ${USER}):$(id -g ${USER}) \
    --name zeitgeist_node \
    --restart always \

docker cp zeitgeist_node:/zeitgeist/data/chains/battery_station_mainnet/network/secret_ed25519 $HOME/secret_ed25519; \
echo $HOME/secret_ed25519

Logs

To the content

⠀Run the Log

zeitgeist_log

⠀Healthy log is below

⠀Open Explorer, type node name and check that your node is exists. If there is more than 1000 node, your node wont be visible due to limit, but it still counts.

Recovery

To the content

Preparing

Particularly recommended for those who participated in the earlier stages

⠀If there is an old node and the secret_ed25519 file has not yet been saved, then save it (the command will start searching for the file on the server)

find / -name secret_ed25519

Linux

⠀Run the node

⠀Upload saved file in the pre-step secret_ed25519 into the folder/services/zeitgeist/

⠀Set permition to the file

chmod +x /services/zeitgeist/secret_ed25519
