# CROW
A marketplace for physical goods using an escrow (hence CROW) based model for payments.
github.com/crow-labs
## Idea
### Short term
Amazon-like marketplace where listed items and transactions are stored and manipulated on a blockchain.

### Mid term
eBay-like marketplace where listed items can be sold in an auction.

### Long term
Point of sale transactions for brick and mortar stores. Payment, from the user's perspective, can be in any IBC denomination with a sufficiently funded Osmosis pool. Using ICA & IBC forwarding and/or grants, the payment received in the escrow address will be in the denomination determined by the producer upon listing the item.
### Description
- We have producers and users whitelists as well as a marketplace
- A producer is a whitelisted address that can list goods on the marketplace
- A user is a whitelisted address that can buy goods on the marketplace
- The marketplace stores listed items
- Governance settles disputes between users and producers
- Item did not arrive
- Item is not as described
- Item is damaged
- Staked addresses can vote for governance and are rewarded for participating in settling disputes
