Jack Platts, a member of the Web3 Foundation, recently launched a new concept called "Initial Parachain Offering (IPO)", which provides a new way for project applications to become a parallel chain of Boca. Platts explained that there are not enough DOT tokens to be a parallel chain slot through IPO crowdfunding. The IPO project needs to deploy a smart contract to raise the DOT. If the funds are raised enough and successfully become a parallel chain, the smart contract will return the previously collected DOT to the investor after the contract expires, as a reward for the recruitment, and another project. It is also possible to issue a corresponding proportion of project tokens as incentives after the IPO is successful. If not selected as a parallel chain or insufficient funds, the smart contract will immediately return the collected DOT to the investor.
