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.

• 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 josh 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)

• • 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.

• • 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)

• The below is how the Battle Ground looks like in the game:

• 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

• 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) .

  • 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 .

• Collection : 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.
