The proliferation of online marketplaces and e-commerce platforms has led to an increase in fraud and counterfeiting. These illegal activities not only harm consumers, but also damage the reputation and profitability of legitimate businesses.

Solution:

Develop a blockchain-based solution that can be used by businesses to verify the authenticity of their products and prevent counterfeiting. The solution should be able to track the movement of products through the supply chain and provide a tamper-proof record of their authenticity.

Criteria for success:

The solution should be able to effectively verify the authenticity of products in real-time.

The solution should be easy to use and integrate with existing business processes.

The solution should be secure and resistant to tampering.

The opaqueness in the government funding process is a major problem in the country, where the beneficiaries do not get the total amount of funds to which they are entitled. There is corruption among middlemen in this process, which restricts the smooth conduction of the government funding process.

Solution:

Develop a blockchain-based solution that can be used by government entities to make their funding process transparent, secure, and effective.

Criteria for success:

1. The solution should be able to effectively conduct the role of the central funding process.
2.  The solution should be as transparent as it should be.
3. The solution should be accessible by both parties i.e. giving and taking entities.

Design a blockchain-based, privacy-preserving digital identity system. The system should allow  users to prove their identity to third parties in a secure and private manner. Additionally,  it should also allow for the creation of verifiable credentials, such as proof of education  or employment, which can be used for various purposes such as opening bank accounts,  applying for jobs, and more.

Solution:

Creating a digital identity system which is verifiable by the peers and consensus. Alot the certificates to that DID and get it verified. The certificates shouldn't be transfered or minted.

Steps for solution:

1. Create a DID system, map the name to the address
2. Verify that DID by the consensus
3. Alot a certificate(it can be any: birth, marksheet, etc)which cannot be transfered or minted
4. You cab use Soulbound Tokens.
5. Verify that certificate by consensus.

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

Problem: 

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 organised 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.

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 chains but how how these NFTs between moved among these chains in decentralised way.

NFTs are currently spread over different chains but how how these NFTs between moved among these chains in decentralised way

Challenge:

Elaborate on a solution that

1. Let NFTs be transferred between chains ( Volary and any EVM chain)

2. Enables cross chain smart contract interaction (e.g. bidding for NFTs from other chain)

Solution:
A blockchain bridge that allows user to export and import NFTs and allows interaction between networks.
