Polkadot Crowdloans: Community Funding Takes Center Stage

Polkadot crowdloans allow projects to raise funds for parachain slots by pooling DOT from the community.

Contributors lock up their DOT, which is then used to compete in a parachain slot auction. In return, they usually receive some kind of reward, often the project's own token.

The Polkadot network links several blockchains together under one shared security system. Projects can join Polkadot and leverage its validators, cross-chain messaging, and overall security instead of building a new blockchain from scratch.
