Web3BlockScanner

This CLI program is an Ethereum block explorer using Web3.js and an Infura Web Socket, built in NodeJS.

You may supply the program either

• 1) a single number, which will be used to analyze all blocks between the current block (cb) and cb minus that number; or,
• 2) two numbers, each representing a blocknumber, which will be used to analyze those blocks inclusive, as well as those in between.

Each Block explored display a summary table, listing:

• 1. The block number,
• 2. The total number of transactions,
• 3. The total number of unique 'from' addresses,
• 4. The total number of unique 'to' addresses,
• 5. The total number of contracts created,
• 6. The total number of contract transactions,
• 7. The total number of uncles.

Before the summary table for each block, the program lists:

• 1. Every unique 'from' address and its total spent that block,
• 2. Every unique 'to' address and its total received that block,
• 3. Every unique contract address.

Finally, a summary table for all blocks explored is displayed, listing:

• 1. The total number of ETH transacted,
• 2. The total number of transactions,
• 3. The total number of unique 'to' addresses,
• 4. The total number of unique 'from' addresses,
• 5. The total number of contracts created,
• 6. The total number of contract transactions,
• 7. The total number of uncles.

Before the summary table for each block, the program lists:

• 1. Every unique 'from' address and its total spent in sum,
• 2. Every unique 'to' address and its total received in sum,
• 3. Every unique contract address.
