What is a blockchain?

• Distributed ledger system; for tracking the transfer of tokens (currency, data of any type).
• A cross between economics, cryptography, and the internet.
  • Side note- if you ever wanted a financial incentive to get involved in cryptography, this is it.
• A blockchain is literally a chain of blocks, where each block contains a list of transactions that everyone agrees have occurred.
  • Each block builds upon all the ones before it.
