## Tasks 

* Form groups of 3 to 5 students
* Complete the contracts together
* Develop and run scripts for “TokenizedBallot.sol” within your group to give voting tokens, delegating voting power, casting votes, checking vote power and querying results
* Write a report with each function execution and the transaction hash, if successful, or the revert reason, if failed
* Share your code in a github repo in the submission form

## Conclusions
Since there where multiple errors at the Goerli network as reported issue at the Lesson - 12 [1], I was unable to
perform this test on the testnet, yet at the end I foundout mumbai network let me do the deployment correctly.
We might require to do self delegation with the team coordination to forefill the tasks at the testnet and 
for new the task was forefilled successfully at the testing enviorment.

## Cesar transactions

Interacted with Contract `'0xaf5bd48C8dd8F733697e148F952c62868A701b71'`

**Call vote method:**

transactionId:
https://goerli.etherscan.io/tx/0x2e211c70bd4b008a8cad147b1543acc93bcba8238157d20de6d47f3707f0b36f

This transaction executes a call to initiate a state change and 'vote' if a user has voting delegations


## Rebecca transactions

### Successful Vote
Vote confirmation: https://goerli.etherscan.io/tx/0x458c495c2caea4585b68bf49ed7be6deeac1df971d48a8da15ae529064e25487

### Main bugs/obstacles/lessons
- goerli wallet was not properly connected
    - did not confirm that my wallet was connected when sending the vote
    - did not change my wallet currency to goerli before reconnecting my wallet; as a result, i almost paid my gas fee in ETH
- did not input the proper information for voting for a specific proposal
    - I kept trying to input a string instead of a number defined in the script. as a result, i kept getting "out of bounds" errors
- had issues understanding how all the code connected
    - like the week before, i am still facing obstables in understanding how each part of the code works together to interact with a smart contract. unlike last week, i've learned that documentation is not enough for me -- i need to reach out to my classmates, TA and programming friends for help. i will now be communicating more frequently with all of them, and setting up study sessions.


## Brent transactions
### First Transaction

#### State Changes
