Shelling Out (Nick Szabo Summary)
TL;DR
Before metal coins, humans used “collectibles” like sea shells and beads as stores of value to solve the problem of trust and time-traveling wealth.
The Problem of Cooperation
Early humans needed to trade but faced the problem of reciprocal altruism. If I help you hunt today, how do I know you’ll give me meat next month when I’m hungry?
The Solution: Collectibles
Nick Szabo argues that humans evolved to search for items that were:
- Durable: Lasts a long time.
- Portable: Easy to carry.
- Hard to Forge: Requires energy or skill to find (Unforgeable Costliness).
Items like shells and rare beads functioned as a proxy for energy and time. By holding a rare shell, you were holding a proof of the effort it took to find it.
Evolution to Bitcoin
Bitcoin is the digital evolution of these early collectibles. It is the first “digital collectible” that is perfectly scarce, portable, and impossible to forge, fulfilling the requirements for money better than any shell or piece of gold ever could.
