Hagglin is a peer-to-peer marketplace combined with a peer-to-peer logistics system, delivered using blockchain technology. There are many marketplaces where individuals can buy and sell goods and services, but the delivery logistics are typically left to more traditional means like postal services, UPS or FedEx. Likewise, many peer-to-peer logistics systems have sprung up in recent years that enable transportation of goods while circumventing traditional delivery services at a far lower cost. However, these marketplaces and systems are all fragmented, and there has yet to be a single platform that combines them in a way that is open and transparent.
