Polkadot is a multi-chain framework that enables interoperability and scalability for multiple blockchains. See: https://github.com/paritytech/polkadot-sdk
Hardware requirements can be found here: https://wiki.polkadot.network/docs/maintain-guides-how-to-validate-polkadot#standard-hardware
Start the service with 'sudo snap start polkadot-parachain'
Check logs from the Polkadot parachain service with 'snap logs polkadot-parachain -f'
Supported configuration options for the snap:
service-args [default=--base-path=$SNAP_COMMON/polkadot_base --name=<hostname>] For available arguments see https://github.com/paritytech/polkadot-sdk The value set here will be passed to the Polkadot parachain binary with a few exceptions listed below.
$SNAP_COMMON/polkadot_base and is not allowed to be configured.endure [default=false] If true the Polkadot parachain service will not be restarted after a snap refresh. Note that the Polkadot parachain service will still be restarted as the result of changing service-args, etc.
Use this when restarts should be avoided e.g. when running a validator.
Example config for running on Polkadot parachain with an RPC endpoint on port 9933:
sudo snap set polkadot-parachain service-args="--name=foobar --chain=polkadot --rpc-port=9933"

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed.
You need first add the snappy repository from the terminal. Choose the appropriate command depending on your installed openSUSE flavor.
Tumbleweed:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Tumbleweed snappy
Leap 15.x:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.6 snappy
If needed, Swap out openSUSE_Leap_15. for, openSUSE_Leap_16.0 if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
sudo systemctl enable --now snapd
sudo systemctl enable --now snapd.apparmor
To install Polkadot Parachain, simply use the following command:
sudo snap install polkadot-parachain
Browse and find snaps from the convenience of your desktop using the snap store snap.
