         Use cases of Blockchain: Application and Interworking
                       draft-yang-usecase-din-01

Abstract

   The purpose of this document is to analyze several important use
   cases based on blockchain, including: blockchain based PKI for
   security device connection, blockchain as a service, interworking
   cross blockchain (exchange data and contracts cross different
   chains).  Through case analysis, important scenarios and specific
   requirements are listed.  Related solutions are also provided for
   easy understanding.

1.  Introduction

   Blockchain helps to establish cross industry mutual trust and
   cooperation, and provides the transmission of value and trust on top
   of current information network (i.e., Internet).  The following
   industries are studying the application of block chains: government,
   commerce, industry, finance, insurance, medical, education,
   communication, culture and art etc.

   Blockchain can play the following role in a company:

   o  Promoting internal cooperation and optimizing the existing
      process, thus improves the production efficiency.  Take an
      Internet service provider for example, the internal blockchain
      that involves product manager, develop team, QA team and service
      team, shall be able to trace each service features design,
      development and market feedback easily, thus accelerate the
      internal productivity.

   o  Improving the cooperation of eco-system players, to enlarge the
      overall benefit.  Take Internet service provider for example, by
      using blockchain, a service provide shall be able to cooperate
      with other other service providers to expand the overall business
      based on trust, such as, a social network service provider can
      coopertate with content (music, video, online game) providers.

   o  Expanding business to the whole industry, the whole society and
      the world, to form new business models.  For example, the social
