Query: A Decentralized and Autonomous Model to Administer University
  Examinations   Administering standardized examinations is a challenging task, especially for
those universities for which colleges affiliated to it are geographically
distributed over a wide area. Some of the challenges include maintaining
integrity and confidentiality of examination records, preventing mal-practices,
issuing unique identification numbers to a large student population and
managing assets required for the smooth conduct of examinations. These
challenges aggravate when colleges affiliated to universities demand academic
and administrative autonomy by demonstrating best practices consistently over a
long period.
  In this chapter, we describe a model for decentralized and autonomous
examination system to provide the necessary administrative support. The model
is based on two emerging technologies of Blockchain Technology and Internet of
Things (IoT). We adopt a software architecture approach to describe the model.
The prescriptive architecture consists of {\em architectural mappings} which
map functional and non-functional requirements to architectural elements of
blockchain technology and IoT. In architectural mappings, first, we identify
common use-cases in administering standardized examinations. Then we map these
use-cases to the core elements of blockchain, i.e. distributed ledgers,
cryptography, consensus protocols and smart-contracts and IoT. Such kind of
prescriptive architecture guide downstream software engineering processes of
implementation and testing
