# My experience of Phala Network Hackathon By [Shubh](https://paragraph.com/@shubh-5) · 2023-08-28 --- This was one of the craziest hackathons i have done till the date. Phala Mainnet Hackathon- LensPhitev2 with Notifications, Dynamic Nfts and on-Chain scores. ------------------------------------------------------------------------------------------ ![Home Page of V2](https://storage.googleapis.com/papyrus_images/7ed33d588f63084b92e1dc376c6640358baea758f71f0283d1c77d8709a66cbb.png) Home Page of V2 * So with very high excitement and enthusiasm we started our mainnet hackathon. * The hackathon started with me not able to setup the sample repo in my windows system till last 2nd day of the hackathon. * I tried updating wsl, deleting, reinstalling and what not. * Then i created a virtual image of a Debian Os and tried to setup the repo there but still we were facing issues there due to some permission issues. * Then my Savior(**hashwarlock ~ josh**) who is Director of Tech Evangelism at Phala Network updated the repo with the code supporting windows system and i was good to go. * Next Day i **skipped college** and coded the backend of the project with josh in our **Developer Dao** voice channel, i had faced many errors(smartcontract, encoding, decoding, tests, variable setting and wat not) but j**osh was there to help** me with them and without him 100% i won’t be able to finish the project. * After setting up the sample code i went through it and understood various parts of the code, the pink package of Phala which can only be used in the code to make http get, put, post requests . * Then i learned how to make API using node and express and deployed my API for storing data about my characters . * This time i also introduced Notifications in the game, whosoever is the winner, a notification about his winning is sent into the public group with his powers and score. * Channel Address of **Live Push Channel**([https://staging.push.org/)(0x0dDda6871f1216D7EF56722167652e4F881d74Aa](https://staging.push.org/\)\(0x0dDda6871f1216D7EF56722167652e4F881d74Aa)) ![Push Notification about winning](https://storage.googleapis.com/papyrus_images/7b2bffbc6b27184a424696d49997d9a58d2922c86a58e7a130c2ef784642506a.png) Push Notification about winning * Following data is stored in the API: * Nature of the character : Fire, Water, Earth, nature, according to this the character gets Power Ups. * Special Attacks: Attack1, 2 and 3 using these attacks the player can have an extra edge against the opponent. ![Api for Querying character data.](https://storage.googleapis.com/papyrus_images/3bfa7d8f284ea8afd8638f2b9297d19960f60e6a7f22704181c66dfeaf10f154.png) Api for Querying character data. * Further we are querying this data using Pink library as a batchttp request with another lens api to query the profile data and we are getting the data in return in form of a array . * Further we are using this array to send data to our Consumer contract deployed on mumbai and then we are listening for event "ResponseReceived” with a webSocket. * Once our React app receives data from the event listener, we are setting that data on our frontend and then starting the game. * Now if the player 1 has Fire Attribute and Player 2 has Water Attribute then Player 1 will get 1000points + because of the Power Attribute. * After the match finishes, the winner gets to mint a Nft of this on-Chain score and if he/she/they already have one then their score on the Nft gets updated. * OpenSea-Collection of Nfts : ([https://testnets.opensea.io/collection/chain-battles-275](https://testnets.opensea.io/collection/chain-battles-275)) ![Nft with Dynamic Levels](https://storage.googleapis.com/papyrus_images/844eceaea4682b7213cb31cc1ddfbc31e201e1d5e6c92307a9d48d05d4d166f0.png) Nft with Dynamic Levels * The below is how the Battle Ground looks like in the game: ![Battleground of LensPhite](https://storage.googleapis.com/papyrus_images/b8c05b1daefa8b9ad5277816dab6e97074cca9d84dc8b6fc582bfa157380ca38.png) Battleground of LensPhite * I hope you liked the project. Phala Testnet Hackathon Experience ---------------------------------- The hackathon started with me getting sick then my teammate got sick then i found a new teammate to code with. and also found a **bug in Lens Oracle** due to which the **oracle gets shutdown** automatically and was **awarded a bounty** for this finding from **Phala Network team**. * I started by exploring Phala Network ,it’s oracles and how things are done. * At start it looked hard but is somewhat easy. * It took me **15 mins** to setup a consumer contract with lens oracle **at start** and now i do it in under **2 mins**. Our Project : Lens Phite with Onchain score ------------------------------------------- ![Battle Ground](https://storage.googleapis.com/papyrus_images/e877dd79f3886fe1f5763df725003187ec8c6a278a45fb7d6100e30bbffeed21.png) Battle Ground ![Landing page](https://storage.googleapis.com/papyrus_images/f24db242ff36cc2203da9b6be2393ccaa656e21e6b46df99fa16ae6e0542e714.png) Landing page \* * It's a Onchain Game in which your lens State acts as your score. * A game of Stat vs Stat for 2 Lens profiles to compete with the stat total they have on their Lens profile * Your total score depends on : * **Your Posts** * **Your Following** * **Your Followers** * We are fetching above data from a **Lens oracle** deployed on **Phala Network.** * A consumer contract is deployed on Polygon-Mumbai to fetch data from Lens Oracle([https://mumbai.polygonscan.com/address/0x8a0ed779d131dAe2Ca8b0a7606e02944Ee611F79](https://mumbai.polygonscan.com/address/0x8a0ed779d131dAe2Ca8b0a7606e02944Ee611F79)) . * If your score is **greater then player 2** , you win. The winner's score is updated in a Unique Nft with onChain Level, and everytime a user wins,the Level is increased . -------------------------------------------------------------------------------------------------------------------- ![](https://storage.googleapis.com/papyrus_images/fb6505079a3ffeffc54f44c817a6ab4d5e36d899b5fc59533d0f6c8426c349c9.png) * Collection : [https://mumbai.polygonscan.com/token/0x16cb27eb3b6e2c3da78e08f54f41b329a6c0b1f3](https://mumbai.polygonscan.com/token/0x16cb27eb3b6e2c3da78e08f54f41b329a6c0b1f3) * The **opponent** is selected randomly for battle . * I would like to give a shoutout to **hashwarlock(** Director of Tech Evangelism at Phala Network) to constantly be available for every help possible be it oracle not responding or some technical error. --- *Originally published on [Shubh](https://paragraph.com/@shubh-5/my-experience-of-phala-network-hackathon)*
