The [Polkadot Championship](https://polkadotchampionship.org/) is an open web3/cryptocurrency contest consisting of a qualification phase and a main event.
The format of a solution is an ASCII string of the form __PC{...}__, like PC{#\This_Could_be_Flagz/#}. A correct solution is also called a flag. What you are looking for in each challenge is to generate the string between PC{......}.
[Submit your solutions in this web form](https://www.cognitoforms.com/UnconditionalPeace/PolkadotChampionshipPrequalification) to ask for an invitation.
To calculate the Keccak-256 hash of a string, you can, for example, install `keccak256-cli` using `cargo`, and then use the `keccak256` command like so:
By the way, you can compound your solutions with an optional 3D design of your own, in the web form. We'll add each such design to the Hall of Fame, where all the successfully qualified players get listed.
The main event's challenges will be disclosed on /TBA, probably 2023-12-04 at 10:00:00 CET/. The teams will need to solve at least one from each challenge track, in 24 hours.
Playing teams will need to choose one challenge as their main one. Additionally, they need to choose at least one from the other tracks and create a proposal for improving the projects.
Overall, three things need to be delivered by the teams: the main challenge solution, a proposal for the second challenge, and a proposal for the third challenge.
The teams need to initialize a git project on https://git.hsbp.org/ or https://github.com/ when the 24 hours start and commit all their development there. Commits after the finish of the end of the 24 hours won't be accepted.
### Judging criteria
Judges will score each team's project based on the following criteria:
- Idea, ecosystem fit
- Is it a realistic project and would it be useful for the ecosystem?
- Logic flow and topology
- Is the logic flow of the program well thought out?
- If this is a proof of concept, did the team think about making the flow better?
- Note: drawing a high-level logic topology is not a must, but good to have
- Presented demo and code
- Did the demo work?
- How well-written is the code?
- Note: the code does not need to be long, but working and should be written during the hackathon.
- Libs/StackOverflow/etc parts are fine, but there needs to be original code.
- Sustainability
- If the presented project would get funding, would it be sustainable in the long run?
- Would anyone keep this project running, would it be interesting enough for the community/users?
- Practicality
- When it comes to using the project, would it be practical or burdensome?
- Note: the proof of concept doesn't need to be like that, but knowing that future improvements would make the project practical is important.
- Security Model
- How is the project protected against threats and abuse?
- Second and Third challenge proposal
- Did the team present a realistic idea for the two other tracks?
- Note: don't spend more than an hour as a team on this, but make sure to do it. 5/5 is the maximum score per proposal.
Each criterion has a maximum score of 10 and the judges will decide individually how many scores they vote for the teams. The maximum score a team can get for their main project is 70. After the scores are finalized, they will be presented in the Hall of Fame smart contract.
