Polkadot Metaverse Championship - Challenges

How to qualify and get a pass to the physical event?

Solve at least three challenges from the four provided in this repository and submit them in the form linked below.

You can find all the four prequalification challenges in the "Prequalification_Challenges" folder. If you played Capture The Flag /CTF/ games before, this process is very similar to you already.

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!

How to verify a flag?

You can verify your flag is correct without submitting the form. Install keccak256 with cargo and compare your findings. Example command:

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
ink - 0x82703a464305aad655e2eb617f31e6e57b7e959bf8528f1d3b5968cc02ed60ac
wss - 0x2f2d4bb11521956c486925241ffcca0cbf7b79bbd9be8eafaeb4fab95713b12d
rust - 0x42ce6fca873fe4dc4ce4d9accdb53e02fdb497ffa6b30f421cea36c81d8ea289
python - 0xf00b792cd63a035c76abe2fca4afe8d8b7eb8527b9b547b672545c71ee4ca77f

Prequalification challenges

WSS challenge: you need to play with a websocket connection and get the flag from the service.

Rust challenge: you need to work with cryptography and math. The correct math will return you the flag.

ink! challenge: you need to get the flag from an already running Substrate node.

Kusamaverse challenge: find the flag in Kusamaverse - this one is very easy, but important for the main event.

We also have an optional 3D design challenge for the Hall of Fame, near the four listed above. If you submit it using the form, we'll add the design to the Hall of Fame, where all the successfully prequalified players get listed.
