You can find all the five prequalification challenges in the "Prequalification_Challenges" folder. If you played Capture The Flag /CTF/ games before, this process is very similar to you already.
2022-10-29 11:59:00 +00:00
The flag format: __PMC{This_Could_be_a_Flag.!}__
What you are looking for in each challenge is to generate the data between PMC{......}.
After you solve at least three challenges, you can submit the form and request your invitation:
__[Prequalify me!](https://www.cognitoforms.com/UnconditionalPeace/PolkadotMetaverseChampionshipPrequalification)__
## How to verify a flag?
You can verify your flag is correct without submitting the form. Install keccak256-cli with cargo and compare your findings. Example command:
2022-10-29 11:59:00 +00:00
```
echo 'PMC{This_Could_be_a_Flag.!}'|keccak256
```
The output of the example command should be: 0x6104a5489b671452684fee77579df24e6f2441d1f8a832c7366cf2cfc5194935
The flags have the following keccak256 values:
```
kusamaverse - 0x896c90f019d0aaa7977ce81c7d7299b1b43d302295f2d567509ab7e3060a797f

2022-10-29 11:59:00 +00:00
rust - 0x42ce6fca873fe4dc4ce4d9accdb53e02fdb497ffa6b30f421cea36c81d8ea289
```
## Prequalification challenges
2022-11-03 17:32:16 +00:00
__WSS challenge__: you need to play with a websocket connection and get the flag from the service. It is called Fibonacci.
__Solidity challenge__: a security audit might reveal what the developers think is private might actually not be.
2022-10-29 11:59:00 +00:00
2022-11-03 17:32:16 +00:00
__Rust challenge__: work with RSA cryptography and math. The correct math will return you the flag.
2022-10-29 11:59:00 +00:00
2022-11-03 17:32:16 +00:00
__ink! challenge__: you need to get the flag from an already running Substrate node or find "another" way. Make sure to web2 scan everything.
2022-10-29 11:59:00 +00:00
__Kusamaverse challenge__: find the flag in Kusamaverse - this one is very easy, but important for the main event.
2022-11-18 17:03:55 +00:00
We also have an __optional 3D design challenge__ for the Hall of Fame, near the five listed above. If you submit it using the prequalification form, we'll add the design to the Hall of Fame, where all the successfully prequalified players get listed.

The details of the main challenges will be shared on 2022 December 6th 10:00 CET. The teams formed before will need to solve at least one from each track, in 24 hours.
