The Story

Nine months ago I started building PP15.ONE — a marketplace where you

can buy, sell, and trade digital land. Today it's live: three different

market layers, a bonding curve engine running in production, and

Islands going live every week.

This is the story of how it came together — and what broke along the way.

What PP15.ONE Is

PP15.ONE is a marketplace where you can buy, sell, and trade digital

land. You can not only buy, sell, and trade digital land — you can

also build your own digital land (called "Islands") and sell this land

to other users.

Every Island has a price that moves on a bonding curve. Buys happen on

the Main Market against the platform. Sales happen on the 2nd Market

between users. There's no sell-back to the platform — once you own an

m², you keep it or sell it on the 2nd Market.

What PPC Are

PPC are in-app credits used across PP15.ONE. They are not crypto, not

a token, not real money.…
