The Safe Exchange is a platform on which any person can create a digital item and also issue a digital contract. The Safe Network allows a person to store any kind of information and communicate any kind of information with cryptographic integrity. Through a client application a user can define an item's attributes and then later offer that item in a contract to a marketplace where other people can discover,scrutinize,and even fulfill the terms of the contract autonomously without the necessity of a 'trusted third party' to intervene in transactions.
