Problem Statement: Recently, institutions are exploring ways to get involved in defi without disappointing regulators and their KYC (Know your customer) requirements. One of the existing proposals on this front is to create private defi platforms, where users need to get whitelisted by a whitelister authority before being able to access and interact with it. Some of the leading defi players are exploring similar concepts, both onchain and offchain. An onchain example is Aave Arc (prev. Aave Pro). 



Challenge: The scope of this challenge is to design a protocol which can be attractive for institutions and other regulated players. Deliver a PoC for the platform and a technically feasible plan for completing the development, focusing on the features in place for making it attractive for regulated entities.



NZZ - Fake News

Problem Statement: The media industry is struggling with difficulties to generate the necessary income to finance real journalism and therefore show the truth behind superficial content floating around on social media platforms and free content providers. The motivation for journalists to dig deep into stories and put their name at risk is shrinking year by year. This leads to the growth of dangerous fake news and conspiracy theories raising the tides in public dialog. The media is an important pillar for information gathering to form our own opinions on extensive topics relevant to our private lives. This development must be stopped, and media must regain its position as neutral source for information.

To turn the tide media must find ways to remumerate researched content and filter fake news to protect the readers from the influence of people and organisations own agendas.


Possible Challenge: Fake news detection. Build a system to validate the source for information. Find a way to guarantee information authenticity or incentivize the data-input of the actors along the value chain.


INDUSTRY 4.0 (Supply Chain)

Bossard - SFL Smart Factory Logistics


Problem Statement: Customers want to have their supply chain as easy as possible on the other hand suppliers want to reduce the effort of their customers as much as possible. There are processes in place which make processes as simple as possible. Bossard for example has the SmartBin (a Box with a builtin scale), whcih measures online the stock level of parts at production facilities. If the stock level is below a certain level, SmartBin orders automatically a defined replenishment quantity at the supplier to refill the box. If the parts arrive at the box, SmartBin measures the increase of parts and the replenishment cycle is closed. This process is quite good automated and works well. With such systems, parts of several suppliers are managed with Supplier Consolidation Service.


The payment of these items is still somehow manual. Supplier sends paper invoices to a service center, which consolidating the invoices manually and creating a consolidated invoice for the customer. After the customer's payment to the service center, the service center deconsolidate the payment and sends it to the suppliers. Such invoices could contain hundreds of positions and the control is inefficient and nearly impossible.


Our current idea is: The customer buy‘s an amount of Bossard-Coins and holds it in his wallet. The order signal from SmartBin triggers a SmartContract. The SmartContract reserves the exact amount of Bossard Coins at the customers wallet to pay the parts. The Supplier accepts the replenishment order: Oracle 1, The Supplier confirms the shipment: Oracle 2, then SmartBin confirm the stock increase: Oracle 3 then SmartContract pays the Supplier with Bossard-Coins.



Challenge: How could we create a stable, lightweight, fully automated payment process? Do a POC on how an IoT Device (like our SmartBin) can be used to initiate and control such a payment process. Prove in the concept how this process can be ensured to be private (between seller and buyer) as suppliers don't want to make their prices transparent and customers don't want to be traceable about their usage of parts.


Bossard SFA Smart Assembly Solution

Problem Statement: OEM produce goods. They are responsible for the quality and with the latest regulations they have more and more the duty to prove the quality. Companies as well as users want to know who is behind a product and how they have secured the expected quality. Transparency is often lost in multi-stage manufacturing processes (component in assembly, assembly in end product). This leads to the problem of traceability to secure transparency in the process. In some cases, product data can be retrieved online from the manufacturer, but this requires trust in the manufacturer's platform which needs to be built up. New technologies will need to build trust and connect us as a manufacturer to our clients.


Challenge: We need a smart tool, who is able to report on a blockchain the results of the quality assessment linked to our assembly line. The data must be secure and transparent to our customers, we must be able to proof that the data cannot be altered in the process. Each product will need an ID or serial number so customers are able to trace it with the relevant information about the quality assessment as well as the given certificate of highest quality.



Canton Ticino - Agro Food decentralized value chain: Cheese!



Problem Statement: Local farmers are always competing with global markets. Discussions about value chains are heating up. The consumers are more eager to know what they are buying, from who, when it has been produced, what production method has been used and so on. We also believe that they'd be interested in helping producers, like farmers, directly, if they want to support the way they are producing healthy food for the community. Farmers and producers are slowly moving in the digitization era, while blockchain technologies are mainly used to link supply chain partners and collecting certificates of quality. There is normally no direct relationship between end consumer and farmer/producer 


We are thinking of how the agro food industry could be supported while satisfying the need of consumers for more transparency. Farmers are no high tech companies so they will need our help to make such a development possible - they need YOU!


Challenge: Build a system to connect the agro-food value chain enabling a direct relationship between farmer and consumer to allow for direct farmer funding, rewards & advance payments of final products, remunerating in advance farmer efforts, while guaranteeing product authenticity and incentivize product quality. The payment should enable the distribution of tokens that can then be used for the collection of the final product. For marketing purposes, the solution should also enable to collect end-user reviews, photos and tips after reception of the final product. Payments and collectibles should occur in a new and practicable token economy model


Show us your idea of a business model and a prototype, how your idea could look like as a solution!




Problem Statement:  In the "DEXVersus Tournament and Duel Center" within DEXGame, players will be able to participate in tournaments and duels with the DXGM tokens they own or purchase.

But as you know, coins and tokens are cryptocurrencies with variable prices.


We think that a system that works with a cryptocurrency based on variable prices for the players does not have a sustainable structure for the gamers and also for our platform.


If we asked you to build a system powered by a fixed value cryptocurrency converted from DXGM token, how would you build this tournament and duel center?


Challenge: You can present the solution for this problem with a system architecture that works on-chain or off-chain. However, hackers who are providing this platform with an on-chain system architecture, will be one step closer to success for DEXGame!


If more than one team presents with an on-chain system architecture, the most successful hackers will be selected considering the superiority about designed system performance metrics.

Gamification of Lugano

Problem Statement: Tourisms is always in a dilemma as there are so many nice spots throughout Switzerland, Europe, and the world. The fight is global as well as regional with a common sense of getting the attention to the regions in general. Travellers on the other side always look for great options to get to know new areas and keep their curiosity returning to these beautiful places. Cities need to be creative to attract many visitors as well as keep the "returning-rate" high. Returning and loyal visitors support the local businesses which are one of the most important assets every region has!


Lugano already joined the Blockchain community and is eager to expand its possibilities using this top-notch technology. The MyLugano App already works with LVGA Points to support local business. MyLugano is the go-to app to live the city of Lugano. The platform hosts an innovative loyalty program to support local businesses built on blockchain and LVGA Points (the Lugano digital currency). Registered App users receive a 10% cashback in LVGA Points on every purchase they made within the circuit. LVGA Points are collected within their app wallet and can be used for make payments within the circuits. Currently there is no gamification nor reward system encouraging users to make a frequent usage of points.


Help us to expand the reach of Lugano and give every visitor a thrilling experience!


Challenge: Ideate a new gamification feature for the blockchain-based city App MyLugano with the goal to increase user engagement and promote the usage of LVGA Points within the circuit for purchases in dozens of shops, restaurants, and service providers.


Today, the cashback earning for every purchase is fixed: 10% of the spending. Every cashback earning or spending generates a transaction on the customer wallet. Our goal would be to increase the app usage, the usage of LVGA Points and increase user satisfaction measured by NPS increase.


We're looking forward to your creative suggestions how gamify Lugano!



Swiss Post

Problem Statement: Today, almost all people use different identities from several identity providers, from banking logins to social media accounts, to be able to use different online Services. This is complex and leads to a lot of risks regarding security and a clear identification of the user logging in. This growing threat of cyber risks leads to the necessity of a unique identification.


In the next few years, new forms of self-sovereign identities will replace today's classic identity solutions (IdP's). Self-sovereign identities eliminate the classic identity providers as intermediaries between users and online services and shift control over the use of identity data to the user. Since today's models are strongly anchored and integrated in the online economy, a solution is sought to enable the transition into the decentrally organized use of identity data and identity related credentials. Without a proper and easy transition option for users this transition won't be disruptive enough and might be nipped in the bud.


Challenge: SwissPost is looking for a solution with which users can transfer identity data from an existing IdP account into their (SSI) wallet by means of an SSI Wallet App and can release them for use in an online service (Veryfier) in the form of Veryfiable Credentials. The solution is to be implemented on the basis of the W3C standards "Verifiable Credentials Data Model" and "Decentralized Identifiers (DIDs)".



Information: OAuth 2.0 or OpenID Connect IDP can be freely chosen such as google, facebook.




Problem Statement: In the world of submitting building permits to municipalities digitalization is slowly accelerating. Still wheels turn slow and on the one hand customer experience is not as its best and and on the other hand bureaucratic effort is unnecessary large. The current solution for handing in building permits is a folder of around 150 papers, taking 3-5 months to process. Besides the overuse of time and resources the disadvantages of that are the lack of insurance of the continued traceability of information over time and the additional costs that occur with each submitted building permit. (Current solution basically not compatible with digital transformation) 


Municipalities have realized this issue and the resulting cost increase. Certain municipalities of Switzerland have requested a digital solution for submitting and storing building permits (as well as their related data, such floor plan, shade simulation data, CAD, etc.). Their requirements are the following: prevent fraud, ensure that historical events can be traced back, and create an open "digital public space" that would make the current submission process more efficient, transparent, and secure. (split public/private).

This real-life use case with the municipalities’ needs, sounds like a challenge we are able to tackle with your help!

Challenge: Context: Nomoko is creating the Digital Twin of the world and is currently providing 3D data (and other information) to certain municipalities in order to contextualize construction projects and simulate their impact on the existing neighborhoods. This digital workflow is now part of their building permit submission process. Additionally Nomoko runs Praedia, a digital marketspace that invites stakeholders of the real estate industry to either seek for, or provide their services in order to make the real estate industry more digital.


We want to see, what for ideas you'd have to answer this request and help to lower the financial and time-intensive hurdles when entering a building permit with municipalities! Design your prototype and show us how this could look! 


Keep in mind: Files need to be uploaded and stored in a cloud (Nomoko will take care of this) but this storage needs to be linked to the blockchain. Once a building permit is uploaded, there needs to be a unique stamp for time tracking and the submission status in order to ensure the traceability. 


The program should be integratable into the ecosystem of Nomoko, so there should be an rest API connection available allowing for users of Nomoko's marketspace to input data through Praedia and for the program to run in the background only returning the processed building permit without additional user interaction. We will for sure provide everything you need!


Lugano Local Economy Reward

Problem Statement: Today local economy is in constant competition with global players with very different possibilities and budgets. COVID brought many back to what is sold in the store around the corner instead of travelling far distances. The City of Lugano sees their local business as part of their DNA and wants to foster the businesses by helping them attract more people buying locally. Especially being so close to the boarder this topic has a very high importance to the region.


Help us enabling this system and support our local businesses! We are depending on your creativity!


Challenge: Develop a SmartContract-based algorithm to promote local economy. Cashback earning is based on a pre-defined "assigned location (home)" and for every purchase users should receive an amount of LVGA Points inversely proportional to the distance from the assigned location. Regarding cashback spending: when using LVGA Points to buy products and services, the user should receive an incentive to spend LVGA near the assigned location.


Today, the cashback earning for every purchase is fixed: 10% of the spending. Every cashback earning or spending generates a transaction on the customer wallet. Our goal is to give users an advantage and incentive in purchasing and spending the cashback near the assigned location. This helps to support decentralized local businesses!









Julius Baer Crypto wallet & bank stable coins


Problem Statement "Wallet": Today wallets are very functional and don't offer a variety of features for more demanding users. The wallet in comparison to a classical bank account is fully in the possession of the user but lacks the options a bank normally provides with their sophisticated banking solutions. This is still a gap to what users are normally experiencing working with other systems. We see a potential to close this gap and give digital investments investors the same options and possibilities like in classical assets. 


We would want to tackle this gap with your help!


Challenge "Wallet": Create a wallet with additional features like for example portfolio analytics, the ability to consume news and research to be up to date while investing, integration of various NFT and Defi options, allowing investments only to be ESG certified and so on, we don't want to limit your ideas! What is a big topic for us is privacy and security, the possibility to add and remove assets (technical acceptance), login and navigation, interactive UI. To solve this challenge, you'll need to work with a blockchain with DeFi support.


Problem Statement "Stable Coin": Currently, there is no Swiss bank coin in place where investors can participate in even though the Swiss banking sector is known for its reliability and longevity. Trust in the Swiss financial system can only be shown by engaging with bank products or accounts. However, investors are interested in a decentral solution. This allows them a broader risk diversification as well as participating in a complete industry. 


Embark with us on a journey how to cover reliable Swiss values in a new coin and offer investors to participate in the Swiss financial system.


Challenge "Stable Coin": Create a proof of concept of a new stablecoin issued by swiss banks against deposits. This coin has a negative interest rate which transfers the coin money to the Swiss national bank. Challenges we see are the coin issuance, ecosystem & acceptance, implementation of (negative) interest rates. The solution should include a dashboard for the coin owners to visualize inflows from transactions.



Swiss Federal Office of Energy

Problem Statement: The electrical power ecosystem is going to have a fundamtental transformation. With increased renewable generation the nature of a formerly centralized power system is changing towards a more decentralized one. Hence, it appears that there is much potential for DLT matching decentralized consumers and further decentralized production, streamline inter-organization processes and automate business interfaces. This is of particular importance for an upcoming liberalization of the electricity market. Then, well known processes for supplier switching, which are carried out often manually today, need to work on a much larger scale, and most importantly integrate the small production sites of renewables (prosumers).    Obviously, the power system and the electricity market procedures are historically grown and are not easily compatible with DLT. Therefore, some analysis work has been performed in order to identify use cases that are most promising for an application with DLT. They have been listed and discribed in a SNV Guide (Guide 1) on DLT in power system. SNV guide 2 lays some technical fundamentals/requirements for a possible power system wide DLT solution. Obviously, the power system and the electricity market procedures are historically grown and are not easily compatible with DLT. Therefore, some analysis work has been performed in order to identify use cases that are most promising for an application with DLT. They have been listed and discribed in a SNV Guide (Guide 1) on DLT in power system. SNV guide 2 lays some technical fundamentals/requirements for a possible power system wide DLT solution.  
Challenge: The challenge is to set a DLT POC for the supplier switching process considering but critically reflecting the SNV Guide 2 on technical requirements for a DLT solution. The DLT solution should (1) Avoid relying on any central authority; (2) Fully automate the switching process; (3) Ensure energy efficiency of the DLT solution itself (avoid proof of work); (4) set up the DLT solution as neutral as possible, i.e. no company or group of companies is in control; (5) Guarantee absolute security and reliability of the system thanks to appropriate control of participants so it can be accepted by the regulator; (6) Ensure that every market actor gets only the information that are necessary for him in the supplier switching process.

SEBA & Lumas - NFT Marketplace

Problem Statement: Non Fungible Tokens are unique assets in the digital world. Blockchain technologies let those assets "live" on chain, be transferable and with the guarantee to be unique.


But there are some limitations coming along with the technology.


NFTs are currently spread over different marketplaces like: (Ethereum), (Solana), (Tezos). Trading between those marketplaces is not easily possible therefore limiting the market size as well as supply and demand.


Challenge: Elaborate on a solution that


  1. 1. Let NFTs be transferred between chains
  2. 2. Enables cross chain smart contract interaction (e.g. bidding for NFTs from other chain)


SEBA & Lumas - Generative Art NFTs

Problem Statement: Non Fungible Tokens have become extremely popular, especially in the art world. The value of these “Art NFTs” is constituted by its uniqueness, the “story behind” and the utility, amongst others.


One of the coolest trends at the moment is generative art, because artists create algorithms to randomly generate visuals (e.g. Art Blocks).


However, blockchain technology is only used to “host” the generated NFTs that have been mostly generated off chain – so far!


Challenge: Rethink how blockchain technology itself can be leveraged to increase the value of Art NFTs. Build a versatile NFT generator/launchpad platform, that enables artists to generate valuable artworks.


What could be a trend beyond generative art? Will it be a dynamic NFT evolving over time? Or an NFT artwork which functions at the same time as a type of entry ticket? Would be possible to create a complete on chain NFT generation experience? 


Deliver a PoC for the platform and a technically feasible plan for completing the development, focusing on the protocol/interface in place for allowing artists to plug their own art idea algorithms.



ZHAW & FairRecycling

Problem Statement: Emission certificates is a fast-growing market. Currently, the registration and administration process of the emission certificates runs via a ‘trusted’ third-party provider like for example IHS Markit. These third-party platforms are clearly profit-orientated and the dependency on them makes it difficult for the non-profit and non-governmental emission certificated trading companies to negotiate acceptable prices. Therefore, the NGOs would favour an efficient, independent, and self-managed registration solution.


Challenge: The goal of this challenge consists of the creation of a decentralized/DLT-based, open and permissionless platform that makes environmental organizations independent of profit-oriented third-party providers in their attempt to register and trade their emission certificates. Blockchain/DLT-based tokens for the emission certificates should encourage the usage of emission certificates to a broader market as partial quantities of a certificate can be issued. To foster an open innovation culture within the emission register and certificate ecosystem, the blockchain/DLT platform solution needs to be open source and should allow the development of other business ideas on top.


This will include coding simple PoC to demonstrate some basic functionalities including emission certificates on the base of tokens. It is expected that the developed solutions will include a) the blockchain/DLT architecture idea, b) a PoC with respect to the proposed technical token infrastructure based on one of the participating platforms, and c) an estimation for the costs and benefits of the solution.



Problem Statement: Following the current NFT hype, retailers are jumping onto the NFT wagon. The possibilities are very wide, and the range of specific uses are uncountable. The question what to make out of this technological possibility is unanswered for many companies thinking of using NFT. We ask for YOU to assist us in this journey finding possible use cases for Richemont.


At Richemont we believe that beyond the hype, NFTs can be useful for the mainstream public in many ways, one of which being by providing pieces of digital art. Looking at the possible target group, it is hard to limit it specifically, thus the target group stays very wide which leads to even more variety in taste of people.


In order to take these assets to the next level and making them accessible and interesting through the ownership period, we believe that these digital art pieces should be enjoyable in different ways, which as of today is not possible without dedicated devices or cumbersome solutions. We want to make each art piece a constant companion for his / her owner to enjoy it in as many occasions as possible. We believe that an NFT experience cross-device, operating system app can greatly enhance the ownership experience. We would love to see how you'd bring all those different systems onto one flexible app.


Help us to augment the experience and thus the value of owning digital art pieces and bring this joy to our customers!


Challenge: By creating a framework on an ecosystem such as iOS or Android, we allow any owner to reuse existing devices which he or she is familiar with, allowing to choose the most adequate based on the situation. By implementing on this framework, we could offer different visualizations or enjoyment options to increase the opportunities of joy and by enabling compatibly with multiple wallets and multiple blockchains (ETH, Flow, Solana, etc..) we give more flexibility.


Our goal is to see a great solution from you that allows art to flow in between all systems!




Problem Statement: NFTs are exploding in popularity and artists are at the forefront of the movement. Many are realizing the massive potential that affords them independence from traditional gatekeepers and allow access and benefits directly to their collectors and fans. Music NFTs have been slower to adopt than visual art. One of the reasons is the lack of clear royalty standards that can take into account multiple owners of a musical work. For example, musicians often collaborate with multiple artists to record a final song and each of the collaborators own a percentage of the final work.

Additionally, there may be other contributors to the work that deserve to be compensated from any initial or secondary sales throughout the lifetime of the piece (which on the blockchain, should be forever). 

NFT marketplaces have not fully integrated robust royalty splits as blockchain standards have not evolved yet to fully take this issue into account. Some proposals exist for split payments on Ethereum 

Eips Ethereum.


Challenge: Create a split payment solution that allows for ongoing automatic revenue splits from multiple owners of a single NFT. Other implementations for inspiration may include how the Zora protocol has been implemented to work with Ethereum.

For this challenge, you can combine Casper’s advanced account features and NFT standard to create this solution. The Casper advanced account management feature is desirable for separating permissions and account actions, supporting delegation, and weighted multi-signatures. 

You can follow this tutorial to learn more. Casper supports non fungible tokens (or NFTs) to track and work with unique digital assets. The Casper standard is the equivalent to ERC-721 known by Ethereum developers. You can use the Casper implementation as a core library in your dApp, or extend it to implement your desired functionality for this hackathon.
