A Ledger Nobody Owns

A blockchain is a shared record that many parties can verify and none can quietly rewrite, and that property is the entire technical claim.

What the Lesson Covers

  1. 0:00Strip away everything else and a blockchain is a shared ledger.
  2. 0:05The problem it addresses. Keeping one agreed record among parties who do not trust a central keeper.
  3. 0:14The chain part. Each block references the one before, so altering an old entry breaks everything after it.
  4. 0:23What it does not give you. It records that a transaction happened. It says nothing about whether it was wise or legitimate.
  5. 0:32The honest summary. A record-keeping technology, with real properties and real limits.
  6. 0:40Understand what it records, and what it cannot vouch for.
