Jiaozi Note
Updated 2026-08-10
INTRODUCTION
English translation pending.
CORE DEFINITION
The Jiaozi was a paper note first issued by merchants in Sichuan during the Northern Song dynasty and later taken over by the state, replacing heavy iron coins in circulation. Its core proposition is that a paper claim can carry the value of the metal it represents so long as holders believe redemption will be honored, which lets the issuer create liquidity and collect seigniorage. The key qualifier is the redemption guarantee: once confidence in convertibility breaks, the note collapses toward worthlessness.
SCAFFOLDING EFFECT
Reduce cognitive load
- Value virtualization: replace a heavy physical medium with a fully redeemable claim against it. - Issuance discipline: keep redemption credible before you expand the supply of outstanding paper claims. - Incentive design: use issuance to shape behavior while carefully watching the confidence it depends on.
Anchor fast decisions
A claim circulates at face value only while holders expect to redeem it, so the issuer's power comes from belief rather than from metal. That belief lets the issuer hand out more claims than it holds reserves, and each new claim buys real goods until holders notice. The system is therefore self-reinforcing up to a point and then abruptly self-destroying.
