The Polkadot Cloud Build Party kicks off on October 6th. Running for 6 weeks, it will feature 3 tracks each with a first-place prize of $3000. Track 1 is Apps that Change the World, where hackers are encouraged to build impactful projects using Polkadot Cloud services. In the second track, hackers will build a chain using the Polkadot SDK or Polkadot Deployment Portal. The third track, Bleeding Edge, is open to all kinds of experimentation, potentially utilizing ZK, XCM, and PVM or other supported smart contracts.
