[NFT] cross-chain universal identity

[LeoHChen]

Description

To build a simple service to map NFT state from Ethereum to Harmony

Context

NFT as universal identity. Use NFT as PFP is popular. Users may choose to use the same PFP across multiple chains. Users don't need to bridge their NFT to Harmony while users can still use the NFT as identity. Noted this is for identity only, but for collateral/trading usage as users may trade the original NFT in Ethereum w/o limitation.

This bounty is to build a simple service to monitor the state of the NFT smart contract on Ethereum and map the corresponding state to Harmony. Running an on-demand or cronjob type service to continuously import the state.

Acceptance Criteria

• [ ] an open-source repo with the design and implementation of the NFT mapper
• [ ] smart contract deployed to harmony testnet/mainnet
• [ ] a whitelist of the NFT mapped from Ethereum to Harmoy
• [ ] the mapping assets displayed on https://bridge.harmony.one
• [ ] demo of the NFT mapper
• [ ] deploy document

@LeoHChen Hi Leo, I was working on this bounty but tonight I find there is already another repository for this at harmony: https://github.com/jhd2best/identity-token-relayer

I'm an hour or two from finishing it ( all core functions are added just need some glue codes and docs ) based on the referenced doc but since I find that repo I'm not sure whether should I continue to work on it or not and whether this bounty is still available or not.

Here is my repo: https://github.com/Ajand/harmony-identity repo is a bit messy because I was not sure whether it was already done or not and I didn't clean it up.
