The true forces shaping the new world.

Ideas to take with you.

1. 01

   Money is a technology for scaling trust past the roughly 150-person ceiling at which shared memory alone can coordinate a group.

2. 02

   If a perfect, unmanipulable ledger of contributions existed, money would be redundant – the ledger itself would do the coordinating work.

3. 03

   Every historical form of money has required someone to maintain the ledger, and that trust has been progressively broken through inflation and gatekeeping.

4. 04

   Bitcoin's design point is not the coin but the ledger – an append-only record of state that approximates the theoretical perfect memory without a trusted keeper.

5. 05

   Reputation behaves like a balance: it can be earned and spent, and spending it without replenishing it eventually exhausts it, regardless of how much was accumulated.
