Origin Protocol
Summary
Origin Protocol provides infrastructure for a general-purpose marketplace.
Users can create offers and put them onto the Ethereum blockchain. Listings data is stored on IPFS, while the metadata is stored on Ethereum.
Origin Protocol doesn’t impose any listing fees, essentially making it a totally free marketplace. Listing data is available for anyone to access and interact with. Therefore, it is an open protocol that anyone can build on. For example, one can create a specialized marketplace by pulling listings related to a specific topic.
