Polkadot Metaverse Championship - Challenges
The Polkadot Metaverse Championship (PMC) is an open web3/cryptocurrency contest consisting of a qualification phase and a main event.
Qualification
To qualify, you must solve at least 3 challenges from the 5 provided in this repository.
The process
Each challenge has its own subfolder in the "Prequalification_Challenges" folder, wherein it is described.
The format of a solution is an ASCII string of the form PMC{...}, like PMC{#\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 PMC{......}.
Submit your solutions in this web form to ask for an invitation.
(If you've played Capture The Flag (CTF) games before, this process should be familiar to you.)
Offline flag verification
You can verify the correctness of your solutions before submitting the form. The flags have the following respective Keccak-256 hash values:
kusamaverse - 0x896c90f019d0aaa7977ce81c7d7299b1b43d302295f2d567509ab7e3060a797f
wss - 0x2f2d4bb11521956c486925241ffcca0cbf7b79bbd9be8eafaeb4fab95713b12d
solidity - 0x81b1ff6939fedd672ddac358a41abb7192ae1f0660a3b1cbf92ef2c82119612b
ink - 0x82703a464305aad655e2eb617f31e6e57b7e959bf8528f1d3b5968cc02ed60ac
rust - 0x42ce6fca873fe4dc4ce4d9accdb53e02fdb497ffa6b30f421cea36c81d8ea289
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:
echo 'PMC{This_Could_be_a_Flag.!}'|keccak256
0x6104a5489b671452684fee77579df24e6f2441d1f8a832c7366cf2cfc5194935
List of 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.
Design for fame
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.
Main event
The main event consists of a 3-day hackathon where projects can be conceptualized and implemented, and also of more challenge-solving in parallel.
At first, teams should be formed by qualified players.
The main event's challenges will be disclosed on 2022-12-06 at 10:00:00 CET. The teams will need to solve at least one from each challenge track, in 24 hours.
Note: You can already prepare libraries and some code before the hackathon, but the final project needs to be conceived during the main event.
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. You can already prepare libraries and some code before the hackathon, but the final ideation and project needs to come out during the main event.
