DeCinema

Decentralized Film production

DeCinema stands for decentralized cinema, It’s a blockchain-based dapp that aids directors/filmmakers to raise funds for their movie and allows each and every individual to be a producer.

Basic Work Flow

• Director/Filmmaker requests for funds for production in DCN token(Decinema token).
• Decinema has a small dex like feature that swaps ETH to DCN and vice-versa.
• The script, poster data is stored in interplanetary file system (IPFS).
• Director/filmmaker raises funds with a fixed amount of interest to be paid back to the contributors.
• Each and every contributor is termed as producer(share holder to the film).
• After the total box earnings from the film, The filmmaker does return the fund with a fixed interest of amount set.
• The repaid funds are then distributed amongst each shareHolder(contributors) with the amount of interest earned on the basis of his/her amount of share.

Challenges we faced

• We were initially trying to store a large set of data like script into the blockchain, which was very expensive in terms of gas.
• We were able to solve it via IPFS.
• IPFS on local node works fine, but we intended the project to be easily available publicly so we used infura's ipfs solution.
• We made sure to keep the dapp as much as decentralized as possible, so we made a payout function that the filmmaker triggers to payout the loaned fund with interest.
• We had mic issues so we used text to audio convertor for videos.

What we learned

#Resources used <br></br>
IPFS - (InterPlanetary File System) - To store script, poster images, etc.
Truffle - Blockchain based development tool.
Metamask - Web extension crypto wallet, and even to connect to test networks.
Web3 - Ethereum JavaScript API to interact with the web-based react with ethereum blockchain.
themoviedb.org - We use themoviedb.org API for dummy film content.
React - A JavaScript library for building user interfaces.
reactstrap - For forms and additional components.
Openshot - To create a pitching video.
For Audio - https://wideo.co/text-to-speech/ (We had some mic issues so we used audio from text software).
