Trust you can carry between stores

Build a five-star reputation on a marketplace and you own... nothing. The stars live on the marketplace's page, under the marketplace's brand, governed by the marketplace's rules. Leave — or get deplatformed — and the reputation evaporates. Years of good business, gone, because the trust was never yours.

The reputation hostage situation

This is the quietest lock-in in commerce. Not the fees, not the logistics — the reviews. A merchant with 2,000 five-star reviews can't leave, because leaving means starting at zero. The marketplace knows this. The fee increases know this.

Customers have it worse: their purchase history, their verified-buyer status, their standing as a good customer — all of it is per-platform. A perfect buyer on one site is a stranger on the next. The trust exists; it's just not portable.

What portable trust looks like

Portable trust has three properties:

1. It attaches to verified transactions. A review without a purchase behind it is an opinion; a review tied to a real transaction is evidence. Portable trust is built on evidence, which is why it can travel — it's checkable anywhere.
2. It belongs to the earner. The customer's trust record is the customer's. The merchant's reputation is the merchant's. No platform holds it hostage because no single platform issued it.
3. It's readable across tenants. A new store can see that a customer is trusted without seeing the customer's private transaction history. The signal travels; the data stays scoped.

This is infrastructure thinking applied to reputation: trust as a layer, not a feature of someone's website.

The honest trade-offs

• Portability needs participation. Trust carries across tenants on the same system. A merchant's TrueStar record doesn't automatically appear on a marketplace that isn't part of the network — portability is real within the fleet, not magic across the whole internet.
• Verified doesn't mean perfect. Transaction-tied reviews raise the cost of fakery — you'd have to buy things to fake them — but determined fraud exists everywhere. Portable trust is harder to game, not impossible.
• Privacy is the hard part. "Readable across tenants" has to mean the signal without the surveillance: trusted, yes; here's everything they bought, no. The scoping is the product as much as the portability.

The endgame of independent commerce isn't just owning your store. It's owning your reputation — the thing that actually makes the store valuable. Trust you can carry is trust you own.
