Open Store is a NFT marketplace where traders can buy and sell NFT tokens through the usage of ethers and track the ownership of digital assets.

• Duplicate Asset Problem: Duplication of digital assets is not possible due to non fungibility of NFT's.

• No Tampering of Data: No one can easily tamper the data as the data is stored on the blockchain.

• Quick Transactions from Polygon: Polygon provided us with quick transaction speed which boosted the User Experience of our website.

• Ownership Record Maintainance: Ownership can be tracked easily as smart contract passes the ownership from the seller to buyer directly.

• Data Storage problem of Blockchain: Blockchain can't be used for storing media files for media assets in an efficient manner, so we used IPFS for digital assets.

• Learning New Technologies: The entire team was unaware of the development technology behind NFT tokens. Consequently, the most difficult thing for us was to overcome the fear of learning a new technology such as blockchain. Thanks to Polygon, we were easily able to build NFT tokens.
• Integrating errors: The integration of next.js backend and blockchain was one the challenges we faced.
• CSS errors : We invested a lot of time in developing the front end from scratch.
• Technical Errors: Many Errors while using blockchain emerged when we tried to merge the next.js with our backend.
• Deploying error: Deploying was also one the challenges which we faced while building this project.
