BlockChain Scraper

A simple blockchain scraper for the ERC721 standard.

Local Chain

1. Install Ganache

Local Chain Setup

1. npm install (inside ./Chain)
2. truffle compile --all (inside ./Chain)
3. truffle deploy (inside ./Chain)
4. mint to mint NFTs to any address
5. setBits to update an NFT's bits

let nftContract = await NFTContract.deployed()
await nftContract.mint('some address', some bit value)
await nftContract.setBits(nft id, new bits value)

App Settings Setup

1. Update ChainInfo data to match local chain or remote chain
2. Assign any private key

Functionality

There are no exposed APIs. This is a worker service that will run once three seconds to check for up to 255 blocks for Transfer, NFTMinted and BitsUpdated events. Existing implementation will create text files that hold a serialized list of NFT data (owners and bits), history of mints, history of transfers and history of bit updates.
