Marketplaces exist to remove risk from peer-to-peer trades and enforce penalties on any actors that misbehave. They also play an important role as rating agencies - enabling customers and sellers to rate those they have transacted with and provide a level of reassurance to others considering a trade with either party. The idea of a fully distributed, peer-to-peer marketplace arises naturally with the advent of the completely decentralized blockchain public ledgers.
There are many implementations of digital marketplaces using various blockchain technologies, utilizing different sets of protocols, added value services and incentives. Naturally, these platforms are concerned with user-to-user (seller-to-buyer, buyer-to-seller, arbitrage-to-buyer & seller) interactions within the context of trading - exchanging goods or services for indirect financial incentives (coins or tokens). While this is expected for any kind of marketplace or exchange, none of these services promote funding worthwhile causes as a central purpose. Being moral and helpful is not the primary driving force behind most economic interactions, but there are ways for this impetus to be incentivized by purely financial means.
Herein, we introduce a distributed, trustless peer-to-peer marketplace with charity and crowdfunding support and an optional arbitration component, where the service is shifted towards verified charity organizations and other crowdfunding initiatives, while the value is expressed in ERC-20 compatible tokens (TRE). While anything could be traded on such a platform, we emphasize the evaluation and trading of unneeded, second-hand goods (from now referred to as clutter) for supporting (fully, partially or symbolically) a charity or a crowdfunding initiative. To put it simply, Tresaro provides an easy way of exchanging your clutter with others willing to buy your items for TRE tokens. Whatsmore, both sides are able to help a cause (or causes) during the transaction by donating items and/or tokens.
