# Jur Chain

The Jur Chain is a Substrate based chain. The Jur Chain integrates the [cumulus](https://github.com/paritytech/cumulus) crate in order to connect securely to the Relay Chain that provides block finalization and security hence making the Jur Chain a parachain, specifically of the Polkadot Relay Chain.

Jur will be bidding for a parachain slot in the upcoming Q1 ‘23; until then it will be running as a solochain. Here is a high level overview of the Jur Chain infrastructure:
