Problem Statement

DappHack is a Web3 hackathon organizing portal. We tend to solve the issues with traditional portals with a perfect merge of web2 and web3 technologies, enabling a great user experience.Problems and how we address them - Chain limitation for sponsors and builders - In DappHack, both sponsors and builders could participate in hackathons with any chain. Builders can pay a Stake in any supported tokens, and sponsors can pay a prize in any supported token.Payment hassles and delays - WIth the on-chain logic of hackathons, all the prize and stake payment handling is done automatically of all tokens at once without the need for much off-chain hassles.Web3 hacks without on-chain proofs - Participating in web3 hackathons with no on-chain proofs doesn't seem apt. With DappHack, builders would get on-chain proofs of their projects as NFTs and hackathons, along with their participation, would be marked in the blockchain forever.

Solution

DappHack is made possible with help of many outstanding protocols. Like Axelar, tableland, saturn, filecoin, push, etc. Axelar is core to our product. All our cross-chain functionalities come with the help of Axelar. We used various Axelar SDKs to write contracts along with their implementation on different chains and integrate them with UI. With the help of Axelar, we were able to provide multi-chain functionalities to our Dapp. We have written some good contracts. We used Tableland as the decentralized database for our application. All the user data, hackathons data, and team and project metadata are stored in tables of Tableland and retrieved globally. This enables databases that are controlled by sponsors and builders only but are accessible globally, a great feature of Tableland. With the help of the new Tableland studio our experience with Tableland was smooth. Filecoin and Saturn - All the data files of images, videos, etc are stored decentrally on filecoin with the help of FVM and retrieved with Saturn. Our NFT data is also stored on IPFS and used to mint NFTs for projects. Thus Filecoin serves as a decentralized data storage solution for DappHack. There are a lot of deadlines and updates throughout the hackathon, missing them could cost a lot. With the help of push protocol, we enable notifications for builders and sponsors as well, enabling a robust hackathon experience for users.
