models, and potentially many more in the
future. The first consensus mechanism is
the mining operation: with the aid of
software, miners review, confirm, and
register transactions. The second
consensus mechanism is prediction
markets. An event might be assumed to
be true if enough independent
unaffiliated persons have voted their
opinion that it is true in a prediction
market. Truthcoin is such a blockchain-
based, trustless, peer-to-peer prediction
marketplace that hopes to resolve some
problems with traditional prediction
markets, such as bias in voters, and
integrate the prediction market concept
with the remunerative coin and public
records structure of Bitcoin.124 Even
farther, Truthcoin aims to provide a
trustless oracle service, registering what
might be relevant events of record in the
blockchain. Some examples of
“information items” of interest would be
the current interest rate, the daily high
temperature, and cryptocurrency daily
high and low prices and trading volume.
For blockchain-based smart contract
operations, independent oracles
providing information are a key
component in the value chain. For
example, blockchain-based mortgage
might have certain interest rate reset
dates in the future that could be
automatically implemented upon having
a trustable source of future information,
such as that registered in a blockchain by
a reputable independent oracle, like
Truthcoin.
Societal Maturity Impact of
Blockchain Governance
A side benefit of blockchain governance
is that it might force individuals and
societies to grow into a new level of
maturity in how topics like governance,
authority, independence, and
participation are conceptualized and
executed. We are not used to governance
being a personal responsibility and a
peer-to-peer system as opposed to
something externally imposed by a
distant centralized institution. We are not
used to many aspects of blockchain
technology, like having to back up our
money, but we learn appropriate
savviness and new behaviors and
conceptualizations when adopting new
technologies. We are not used to
decentralized political authority and
autonomy.
However, we have matured into the
reception of decentralized authority in
other contexts. Authority floating freely
has already happened in other industries
such as information, wherein the news
and publishing industry became
decentralized with blogging and the
restructuring of the media industry.
Entertainment is similar, with corporate
media properties existing alongside
YouTube channels, and individuals
uploading their own content to the Web.
The value chain has exploded into the
long-tail format, and individuals became
their own taste makers and quality
arbiters. A crucial twenty-first-century
skill is that individuals must examine
content and think for themselves about
its quality and validity. The Bitcoin
revolution is the same thing happening
now with currency, economics, finance,
and monetary policy. It might seem
harder to let go of centralized authority
in matters of government and economics
as opposed to culture and information,
but there is no reason that social maturity
could not develop similarly in this
context.
Chapter 4. Blockchain 3.0:
Efficiency and Coordination
Applications Beyond Currency,
Economics, and Markets
Blockchain Science: Gridcoin,
Foldingcoin
As blockchain technology could
revolutionize the operation of other
fields, innovators are starting to envision
how the concepts might apply to science.
So far, the main thread is related to peer-
to-peer distributed computing projects
for which individual volunteers provide
unused computing cycles to Internet-
based distributed computing projects.
Two notable projects are SETI@home
(the Search for Extraterrestrial
Intelligence, which uses contributed
computing cycles to help analyze radio
signals from space, searching for signs
of extraterrestrial intelligence), and
Folding@home (a Stanford University
project for which computing cycles are
used to simulate protein folding, for
computational drug design and other
molecular dynamics problems). Per
blockchain technology, remunerative
coin has been set up to reward
participants in both the SETI@home and
Folding@home projects. For
SETI@home, there is Gridcoin, which is
the remunerative coin available to all
BOINC (Berkeley Open Infrastructure
for Network Computing) projects, the
infrastructure upon which SETI@home
runs. For Folding@home, there is
FoldingCoin, a Counterparty token that
runs and is exchangeable to the more
liquid XCP cryptocurrency (and
therefore out to Bitcoin and fiat
currency) via the Counterparty wallet
(Counterwallet).
A more fundamental use of the
blockchain for science could be
addressing the wastefulness of the
mining network, which consumes
massive amounts of electricity. Instead
of being used to crunch arbitrary
numbers, perhaps the extensive
processing power could be applied to
the more practical task of solving
existing science problems. However, a
mining algorithm must meet very
specific conditions, like generating code
strings or hashes that are easily
verifiable in one direction but not in
