Polkadot & Kusama Parachain Crowdloan

A Parachain (“parallel blockchain”) is an individual Layer 1 blockchain that runs in parallel with the Polkadot and/or Kusama ecosystem. When connected to the Relay Chain — the Layer 0 multi chain network at the heart of Polkadot — Parachain teams can benefit from its governance, security and interoperability to build a variety of applications and use cases.
At the time of writing, the Polkadot Relay Chain can support only a limited number of Parachains (about 100). With nearly 400 projects currently building on top of Polkadot and Kusama, this creates a scarcity of Parachain slots, which will be allocated to teams via a series of Parachain slot auctions in 2021.
