[Front-end] Impement Optimistic Update

[thanvinhbaohoang]

Problem:
Currently the when Attestation is made, there is a very long wait time on Client-side to wait for the Attestation to be confirm

Solution
Implement Optimistic confirmation for Attestation so user would not have to wait for confirmation
Then there can be a Toast or Snackbar that pops-up to announce when an attestation is confirmed

There are two transactions: one for submitting the IPFS hash and another for attesting,
The user must confirm both

Optismistic Update is a Front-end User Experience thing. Instead of having a Relax Loading Screen, Our app would simply tell user the action was done while not having confirmed the transactions on the blockchain yet.
