This document discusses blockchain technology and its potential applications. It begins with defining concepts like value and intermediaries in society. It then provides a basic explanation of blockchain as a distributed, transparent and immutable record keeping system. Several examples are given of how blockchain has already been used, such as Bitcoin transactions, land registry, and social welfare payments. The document argues that blockchain cannot be undone and could shape future generations, so it is important to understand its impact. Both pros and cons of the technology are outlined.

Blockchain for
social welfare?
"We started a small trial in
the north west, designed
to see if we can send
welfare payments using
this technology, and
more importantly, to see if
people reliant on welfare
payments would benefit
from this approach."

Safe delivery with
Drones?
Encrypted microchips are used
to give automated delivery
drones a unique identity on the
blockchain which IoT
applications can use to allow or
restrict drone access to
locations such as a home or
warehouse.
