Inspiration
We wanted to build the largest Private and public decentralised digital items store that promotes freedom, direct interaction with lovers of your work, and having direct connection to digital item sales like ebooks, videos, audios, certificates in the fastest way possible
We wanted people to have a safe secure private and permanent place to store private digital items like files, secretes etc, we also wanted people to be able to make money of the digital items they wish to make public, hence the public library market.
We see this being used in the meta verse too, where do we want to store our files when in the metaverse? Evmos-Lebium!
What it does
EVMOS-Lebium is a platform that helps store your files on the blockchain with the help of ipfs and lit protocol(we are still researching lit protocol to encrypt the ipfs cid). These files can be shared publicly to everyone in the world for free, files can also be uploaded privately and shared to another user, and lastly private files can be put up for public sales.
How we built it
We wrote a smart contract which contained the following:-
A privateUpload function, for uploading contents privately, which takes in a name, link, description and category, which is then pushed to the private library array. A publicUpload function, for uploading contents publicly, which takes in a name, link, description and category, which is then pushed to the public library array. A share function, for sharing private library content, which takes in an array of addresses of receivers, and the item ID. A publicSale function, for putting up contents of your choice from your private library for sale publicly, takes in the array ID, and the price in Wei you want to sell the content for. And the buyItem function, the most interesting part, which takes in the array ID of the content you want to purchase passed by the front end. For this, the payment is made in the native coin
Challenges we ran into
Had difficulty using Infuras Ipfs gateway to upload and retrieve our Items
Accomplishments that we're proud of We have learned a lot of things, and it's amazing that we were all able to come together to work on something that can be used by people in real life. We're most proud of our personal growth as developers
What we learned
We have learnt about ipfs, evmos,Infura
What's next for EVMOS-Lebium
We want to see how we can make this a more stable and efficient library. Perhaps become the biggest decentralised digital items store. We also want to perfect the litprotocol as a middle ware for encripting and decripting the ipfs content Id , that way it becomes completely private(reaserch is currently on going for this).
