ONBOARDING VALIDATORS

Please join our Discord for up-to-date information on our network and validator onboarding.

SYSTEM ADMINISTRATION

Although Avail is in testnet phase, in general, users should have significant system administration experience when running validator nodes.

Validator nodes are responsbile for maintaining and securing the network by staking tokens with real value. Validators need to understand how to manage their node, its associated hardware & configuration, and be wary that they are subject to being slashed due to actions like being offline or equivocation.

When in doubt, reach out to the Validator Engagement team.

Update and install packages for compiling

sudo apt update
sudo apt install make clang pkg-config libssl-dev build-essential

User Management

Running in user (Assume) : admin We never used this username in our production !

Login as User admin

su - admin

or

sudo su - admin

and make sure we are in directory

pwd

/home/admin

Running in user : admin

Create directory

mkdir -p ${HOME}/avail-node
mkdir -p ${HOME}/avail-node/data
mkdir -p ${HOME}/avail-node/systemd

Download The Required Files

go to dir /avail-node for the setup validator

cd avail-node

wget https://github.com/availproject/avail/releases/download/v1.8.0.0/amd64-ubuntu-2204-data-avail.tar.gz

Extract File

tar -xvzf amd64-ubuntu-2204-data-avail.tar.gz

cp amd64-ubuntu-2204-data-avail data-avail

Create Systemd

export USERNAME=$(whoami)
cat > ${HOME}/avail-node/systemd/availd.service  <<EOF
