consider the potential economic models
for M2M/IoT payments, we must work
out general coordination protocols for
how large swarms of devices can
communicate, perhaps deploying control
system and scheduling software for these
machine social networks, adding new
layers of communication protocols like a
“chirp” for simple microcommunications
such as on, off, start, and stop. 161
In the farther future, different classes of
blockchains for different kinds of
applications could be optimized. Maybe
there could be daily purchase
blockchains for the grocery store and
coffee shop purchases, and others for
large-ticket items like real estate and
automobiles. More stridently different
functionality is needed for noneconomic-
market blockchains, for government
services, intellectual property
registration, notary services, science
activities, and health-record keeping.
The key question is distinguishing the
economic principles needed for the
different range of functions with which
blockchain technology could be helpful.
However, not every operation is one of
value registration and exchange.
Not all of the ideas described need a
blockchain; they do not require
sequential, public, and distributed data
storage. They could instead be
implemented through other technology
such as cloud storage or distributed
computing models more generally.
However, blockchain technology could
be included to provide additional
functionality, and further, it is not
possible at present to see all of the
potential future benefits and uses of
blockchain technology that might
emerge.
Another reason that the blockchain is not
for every situation is because we do not
want to “economify” everything. We do
not want to reduce the qualitative
aspects of life to a purely and nakedly
economic situation. The idea of a
remunerative coin accompanying many
more situations and making the
economics of situations more explicit is
welcome in some ways but repugnant in
others. However, the broader
conceptualization of economy evoked by
blockchain technology invites a new
consideration of the notions of transfer,
exchange, and acknowledgment that is
deeply qualitative and could persist
even as blockchain-enabled features do
not (and should not) become
omnipresent.
Centralization-
Decentralization Tension and
Equilibrium
There is a mix of forces both toward
centralization and decentralization
operating in the blockchain industry. In
fact, it is the blockchain that has defined
the landscape of models to comprise
those that are both centralized and
decentralized. Aside from the Internet,
there have not been many large-scale
standardized decentralization models
that have been readily conceptualized
and used in different contexts to organize
activity. Even though decentralization is
the core enabling functionality of
blockchain technology (the decentralized
trustless cryptographic transaction
recording system and public ledger),
there are also many centralization
pressures. One is the centralization
forces toward developing the standard
plumbing layers of the blockchain
economy. The Bitcoin blockchain has 90
percent cryptocurrency market
capitalization, and some projects
consider it safest and easiest to build
protocol 3.0 ideas on this installed base
without having to mount a mining
operation on a new altcoin blockchain.
Mining is another area upon which there
are many centralization pressures. The
fierce competition has driven mining
from individuals with mining rigs to
mining pools and custom ASICs such
that a few large mining pools register
most of the new Bitcoin blocks and have
started to reach the 51 percent threshold
of controlled hash power, which could
result in a mining takeover. It remains to
be seen how forces toward economic
efficiency through centralization and
trustless exchange through
decentralization will come to
equilibrium.
Chapter 5. Advanced Concepts
Terminology and Concepts
The blockchain economy is triggering
the invention of many new ideas and the
reappropriation of existing concepts and
terminology in innovative ways. It
prompts investigating the definition of
terms that have been taken for granted
and passed unquestioned for years, such
as
underlying definitions and the
reappropriation of terms position these
concepts more openly and accessibly for
application to current situations.
Blockchain-related concepts are more
actively in people’s minds and ready to
apply at the generalized level. For
example, consider a library. At the more
generalized conceptual level, a library is
a system of value exchange; there are
product and service offerings, like books
and research, being taken up by those
with whom the value proposition
resonates. New models like blockchain
technology force us to consider reality at
the more generalized level of the
concepts behind a specific instantiation.
This leads us to imagine other specific
situations that could be realized with
those concepts. For example, a
blockchain is a technology for
