Polkadot Metaverse Championship - Challenges

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

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

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.

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-cli 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
wss - 0x2f2d4bb11521956c486925241ffcca0cbf7b79bbd9be8eafaeb4fab95713b12d
solidity - 0x81b1ff6939fedd672ddac358a41abb7192ae1f0660a3b1cbf92ef2c82119612b
ink - 0x82703a464305aad655e2eb617f31e6e57b7e959bf8528f1d3b5968cc02ed60ac
rust - 0x42ce6fca873fe4dc4ce4d9accdb53e02fdb497ffa6b30f421cea36c81d8ea289

Prequalification challenges

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.

Rust challenge: work with RSA 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 or find "another" way. Make sure to web2 scan everything.

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 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.

Challenges for the main event

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.
