-#  DAO Track
+#  The Instituational Track: DeGov
 
 ## Description
 
-A DAO (Decentralized Autonomous Organization) services pre-defined goals - groups use it to reduce coordination failure and improve collaboration, security. It is an organization managed in whole or in part by decentralized computer program(s), with reputation system, voting and resoures handled through a blockchain. 
+The Institutional Track, known as DeGov (Decentralized Governance), is designed to explore the application of decentralized governance models in institutional settings. This track focuses on creating innovative solutions that enable more democratic, transparent, and efficient governance structures within organizations, governments, and other institutional entities.
-
-How would that look like as a DAO, on top of Substrate? Or Gear Protocol is enough? Or just cryptography?
 
 ## What to do on this track?
 
-You need to implement a DAO structure. You can use all technologies existing in the Polkadot ecosystem, however Substrate is preferred.
+Participants aree tasked with developing decentralized governance systems, tools for voting and decision-making, and systems for managing institutional processes in a decentralized manner. The goal is to create scalable and secure solutions that can be adopted by large entities to improve governance and stakeholder participation.
 
-Topics you can choose from:
+## Use-case ideas
-1.  __Educational DAO__ - Every organization needs education, some of them are heavily focused on that specific aspect. Can we replace MOOCs, academies or universities with a DAO or these would be important parts of it? Create a DAO that incentivizes the participants to learn and teach each others about Web3. Consider the human factors, different roles, resources and how those would be handled to have a long-term future, topology, incentives, risks.
-2.  __Government DAO__ - How could a country work as a DAO? Create a system that provides basic funcionality for your imaginary decentralized country. Tip: you can use OpenGov or QRUCIAL DAO's reputation system in your implementation. Consider the following: How would people interact with the system? What incentivizes the members to keep running as a DAO? How do you avoid centralization efficiently? What are the risks and anti-fraud mechanisms?
-3.  __Turn an existing project DAO__ - Choose a project from the Polkadot ecosystem and work out how it could continue as a DAO. You can choose any of the already existing parachains (those that are not DAOs). Examples: Mosaic Chain, Interlay, Mandala Chain or CCTF. You can use all existing services, but need to implement the exact thing(s) that would turn these into DAOs.
 
-The submission will be evaluated based on the strength of the idea and the delivered proof of concept code. Substrate or Gear Protocal are preferred, but not a must - you can use EVM too. We give you a very free hand over the idea and the implementation, but it needs to be realistic and useful for the ecosystem.

+## Unique Network - Specific Challenge
+
+Topic: NFT as a data containter
+
+Type: Data obfuscation in an on-chain NFT record - managing data access and visibility.
+
+Description: The challenge is based around the concept of on-chain and off-chain data storage accessibility in terms of data obfuscation. Unique Network NFTs provide a very flexible mechanism for storing data both on-chain and off-chain including handling mutability and rights in that respect (who can modify). The question of who is allowed to see the raw data is a completely different issue and is handled at the application level. Your task is to come up with a simple mechanism which allows data obfuscation of data stored via the NFT providing a way for an application to manage which data can be publicly visible and which is obfuscated and availible only to the application. There are no limitations set in regard to how obfuscation is performed, it is entirely in at the discretion of the developer/hacker.

+

-# Security and Privacy track
+# The Physical Track: RWA and DePin
 
 ## Description
 
-This track is about improving the security and privacy of the ecosystem.
+The Physical Track focuses on Real-World Assets (RWA) and Decentralized Physical Infrastructure Networks (DePin). This track aims to bridge the gap between the digital and physical worlds by leveraging blockchain technology to tokenize and manage physical assets, as well as to build decentralized networks for physical infrastructure.
 
 ## What to do on this track?
 
-Choose one from the list and implement a meaningful system related to this track's topic:
+Participants work on projects that involve the tokenization of real-world assets, such as real estate, commodities, or physical products. Additionally, they will develop decentralized networks and protocols that facilitate the management and operation of physical infrastructure, ensuring transparency, security, and efficiency. They can mix the two technologies use choose to build only RWA or only DePin focues programs, applications.

-The project you deliver needs to have seamless integration (to wherever it applies), should not make the systems too complicated to use or manage. ZK and pure cryptographic implementations are preferred. You can think about ideas like: When you see someone's message, how can you verify it is really from that person, eg. in news/web3 socials/etc? How can you catch malicious activity on blockchain, for example in games? How to stop fraud? How to tell someone s/he is allowed to do something without revealing their identity?

-Is this a crazy idea or there could be realistic and meaningful implementations where AI is running on top of blockchain?

-You need to reveal Gandalf's 8 words and create a chain of blocks with them: https://gandalf.lakera.ai/
-
-Task is the create a local blockchain (no consensus/networking needed here):
- - Beat Gandalf AI game, find all the 8 words. Put them in order. Each one of them will be the data in your block.
- - Use | as delimiter between the words and the hash. Between the word and the hash, there is a - sign.
-        - How this looks like: GENESIS|WORD1-HASH|WORD2-HASH|WORD3-HASH
- - Use SHA512 for the hashing algo. Start with the word and the delimiter and the first word: "GENESIS|WORD1-"
- - Make sure to calculate the dash sign into the next hash. It is part of the block data. You only add the hash from the previous block, not all data!
- - Everything is UPPERCASE.
- 
-If you are doing it correctly, you will have the following block hashes, starting from 0, Genesis:
