Introduction

• Concepts come in order of dependence.
• Essentially, I try to explain something before I reference it.
• If something doesn't make sense, move on and then come back to it and it will probably make more sense.

New Blockchain Concepts

• Automated Block Hash Auction (ABHA)

• Produces non-fungible items at designated block intervals.

Just going to leave this here... the future will see hundreds of thousands of single dapp chains.
Different services have different transactional demand.
Having multiple services on the same chain is like forcing people to pay for jet fuel whether
they are flying across the planet or just mowing their lawn.

REMIX EXAMPLE PROJECT

Remix example project is present when Remix loads very first time or there are no files existing in the File Explorer. 
It contains 3 directories:

1. 'contracts': Holds three contracts with different complexity level, denoted with number prefix in file name.
2. 'scripts': Holds two scripts to deploy a contract. It is explained below.
3. 'tests': Contains one test file for 'Ballot' contract with unit tests in Solidity.
