Data money: The sociotechnical infrastructure of
cryptocurrency blockchains
Koray Caliskan
Abstract
Drawing on an empirical study of cryptocurrency white papers, this paper proposes an actor-based taxonomy of cryptocurrency blockchains. First, it describes
the evolution of blockchain architecture with reference to the economic services
that blockchains supply. Second, it discusses the socio-technical platform of
blockchains as proposed in cryptocurrency white papers. Third, it analyses the
socio-economic consequences of these technically diverse blockchain platforms,
by proposing a taxonomy of their digital architectures in reference to two
groups of actors that maintain blockchain infrastructure: transactioners and
accountants. Defining cryptocurrency as data money, and locating cryptocurrency
ownership as the possession of an exclusive right to move data privately in a public
or private space, the paper describes a blockchain as a digital actor-network platform that makes it possible to define and distribute these data transfer rights.

Economy and Society
cryptocurrency blockchains have been forging a parallel monetary economic universe that may need neither states nor banks for minting and transferring currencies. In less than a decade, the market capitalization of cryptocurrency economic
universe reached US$820 billion, exceeding 89 per cent of the world’s national
economies by December 2017, when Bitcoin’s closing price briefly exceeded
US$19,500.1 By January 2020, there were 5,035 cryptocurrencies, traded in
more than 20,317 cryptocurrency markets all over the world, making them the
most varied money and most rapidly emerging market form in history.
Journalistic accounts of these currencies draw on clashing reactions: Those
who are under the spell of Bitcoin schadenfreude have described it as a bubble
that is doomed to vanish. An influential editorial has called it ‘a greater fool’s
gold’ (The Guardian, 2018). Bitcoin evangelicals see a revolutionary potential
in it. They believe that it facilitates autonomous economic action in a
beyond-political world without any state intervention (Tapscott & Tapscott,
2016). Academic literature disagrees. Research has shown that money is not a
thing, but a process, produced and maintained by social relations and political
institutions (Dodd, 1994; Hart, 2000; Zelizer, 1994). We also know that the
bursting of the dot.com bubble did not prevent Silicon Valley from giving
birth to the world’s first trillion-dollar companies, such as Amazon. Therefore,
many academics are not convinced that Bitcoin’s volatility will bring about the
end of blockchains and cryptocurrencies (Bjerg, 2016; Dallyn, 2017). Furthermore, it has been shown that these new currencies are ‘multi-faceted, politically
contested and sociologically rich in [their] functions and meanings. There is not
one Bitcoin, but several’ (Dodd, 2018, p. 36).
Scholars have also shown the very political universe of Bitcoin proliferation
(DuPont, 2017; Golumbia, 2015). Almost 80 per cent of Bitcoin mining in
2017 was carried out by five mining pools only, thus implying power asymmetries (Swartz, 2017). The assumption that states and banks cannot control cryptocurrencies creates the illusion that a blockchain operates without institutional
mediation undergirding social and political relations (Nelms et al., 2018). Banks
and states have been using and producing blockchains at a time when blockchains are presented as the historical instrument to undermine their power.
This detracts from the credibility of evangelicals who argue that blockchains
are anti-system, anti-capitalist and anti-state.
However, there exists one gap in the emerging literature: The scholarly literature addresses this new development in two ways, neither of which are adequate for explaining and analysing the working of blockchains and
cryptocurrencies. First, micro-economic research on crypto-assets builds
models that draw on problematic neoclassical assumptions concerning how
actual markets work (Ciaian et al., 2016; Jang & Lee, 2018). Such studies
assume that the specific nature of the commodity and the socio-political
nature of its universe have no significant effect on how their prices are made,
whether in pork belly or in Bitcoin. As empirically demonstrated in the literature, both the nature of the object of exchange and the infrastructure of the
market itself have formative effects on prices. This infrastructural dimension
Koray Caliskan: Data money

of markets has to be studied, not edited out (Barry, 2013; Callon, 1998; Lépinay,
2011; MacKenzie, 2006; Roitman, 2005; Slater & Tonkiss, 2001).
Yet, predominantly digital infrastructures such as blockchain are different from
predominantly non-digital infrastructures such as roads, electricity networks and
irrigation canals. To Larkin (2013) ‘infrastructures are matter that enable the
movement of other matter’ (p. 329). However, computer programs and data are
not matter; they are protocols or representations that operate in/on matter that
consumes electric power, all made possible by labour power. Blockchains are infrastructures that enable the movement of data as representation and value. In a world
where all infrastructures are being entangled with varieties of digitality, digital
infrastructures, like blockchains, require from social researchers a critical and
empirical attendance to the specificities of socio-technical universes they build. I
do not assume an essentialist ‘nature’ of digitality apart from material things, but
draw on the analyses of materiality of representational objects like data and algorithms as illustrated by Dourish (2017). Like constitutions, protocols constitute
relationships by imagining rights, subjects, objects and trajectories of action and
inaction. But unlike constitutions, one cannot disobey them, for they make
action impossible if one does not follow the trajectories of movement that they
define. They display syntax error, unless they are hacked. Yet for the actors that
cannot be defined by the computer code, infrastructural inversions are almost
always the norm (Jensen, 2017; Morita, 2017).
Second, many analysts either show what cryptocurrencies are not, or how
these currencies are not new. With exceptions such as (Dodd, 2018; Maurer,
2017; Parkin, 2019; Rella, 2020; Shaw, 2016; Swartz, 2017; Zook & Blankenship,
2018) the existing social science literature rarely draws on empirical social analysis; it interprets blockchains and cryptocurrencies either by drawing on anecdotal experience, or on the theoretical premises of the very empirical
developments they aim to understand. This literature has been critiqued by
showing their inclination to treat their assumptions as conclusions instead of
starting out with an empirical analysis of how blockchains take place in
various economic contexts (Garrod, 2019; Jones, 2018). It is this gap in the literature that this paper addresses, by offering an actor-based taxonomy by
empirically analysing cryptocurrency blockchain white papers.
Theoretically, the argument draws on studies of economization, as discussed
by Çalışkan and Callon (2009, 2010). The study of socio-technical infrastructures
plays a crucial role in making sense of economic action and agency, because they
structure possible fields of action in identifiable ways (Anand, 2012; Appel, 2012;
Barry, 2013; Brian, 2013; Elyachar, 2005; Foucault & Gordon, 1980; Harvey &
Knox, 2015). However, one has to be careful against reviving sociological structuralism, this time in the form of infrastructuralism. It would be problematic to
categorically propose that infrastructures are primary frameworks that give
birth to secondary social behaviour or ‘the action’.2 Networks can determine or
have a larger say in how actors behave, but this is a possibility, not a rule.
Adistinctionshouldbemadebetweeninfrastructureand architecture.Infrastructures arrange the ways in which architectures, that are built on them, connect and
4 Economy and Society
bypass eachother.Theyaremeta-structuresthatmakepossiblethebuildingofarchitectural designs that harbour and form possible trajectories of action. However,
depending on a strategic vantage point, structures may function like infrastructures.
The internet is infrastructural to blockchains, and a specific blockchain can be infrastructural to the architecture of a cryptocurrency exchange. In economization
relations enmeshed in digital materialities, infrastructures and structures are not
static things where matter makes other matter flow. They are dynamic processes
whose function changes according to the vantage point one approaches these
relations. In that context, the term ‘socio-technical’, or better still, ‘socio-digital’
refers to an assemblage or agencement of devices, representations, and actors
whose interaction produce empirically observable consequences that may, in turn,
change the infrastructure itself. These socio-digital assemblages, that may take the
form of a stack economization on platforms such as cryptocurrency exchanges,
equip agents with devices of action to be deployed in contexts that shape and are
shaped by human intentions, interests, mistakes and plans.
The empirical research draws on the white papers of the most valuable 100
cryptocurrencies as of 1 June 2018. Almost all cryptocurrencies are offered
with a ‘white paper’.3 These are position papers, written by anonymous,
known individuals or groups of individuals, historically making cryptocurrency
or Data Money as the first money form that is created, in part and in varying
degrees, by scientists or people who use scientific and designerly competences,
and without the contribution of banks and states. These more than 2,000 white
papers now make up an oeuvre longer than 50,000 pages. Most of these documents, however, introduce cryptocurrencies of only negligible economic value.
As of 1 June 2018, the most valuable 10 cryptocurrencies represented 75.01 per
cent and the most valuable 100 cryptocurrencies carried 90.06 per cent of all
cryptocurrency value in the world.4
Providing researchers with an opportunity to study the evolution of blockchain architectures, white papers develop, describe and present major forms
of blockchains and their respective cryptocurrencies. The first part of the
paper presents the evolution of blockchains from the value-exchange-distributed ledger of Bitcoin and smart-contract-exchange platform of Ethereum, to
market-making blockchains like Cybermiles and interchain platforms that aim
at bridging separate blockchains themselves, such as Aion. Without developing
a critical awareness of the socio-technical evolution of these digital ledgers, one
cannot grasp the specificity, nature and consequences of their architecture.
Blockchains draw on imaginaries of digital metallism (Maurer et al., 2013), a
discursive framework that grants blockchain projects tools of intervention in
actual economic universes, yet by making it difficult to understand blockchains
if one uses these metallistic analogies that blockchain architects themselves use.
Digital metallism has a reverse discursive thread that represents material processes as if they were not physical or material, which may be called intangibilism.
References to the ‘cloud’ are a good example. ‘Clouds’ are located in warehouses
that dot the global countryside, not up in the sky as if they were intangible
things.

The term ‘Bitcoin mining’ exemplifies this elusive nature of blockchain architecture well. One does not dig out data to find Bitcoins in a digital mineshaft.
Mining, an analogical concept Satoshi Nakamoto used for the first time in his
Bitcoin white paper, is a form of computational accounting for whose practice
the underlying protocol rewards the accountant with cryptocoins. Furthermore,
cryptocoins are not coins per se, but digitally represented exclusive rights to send
data privately in a public economic space.5 Market actors exchange these
specific rights and trade these digital coins for services and goods.
The second part of the paper introduces a descriptive presentation of the
content of white papers, their writers, their arguments’ scientific qualities,
and their imaginaries. In this section, drawing on a computational text analysis
with R, we see that white papers theorize the maintenance of reintermediations,
markets and economies in a social context. Furthermore, these white papers, all
written in English and by male authors, propose a specific social world that
draws on a bifurcation between digital and non-digital things.
The third part presents an actor-based taxonomy of blockchains in terms of
their control mechanisms which structure identifiable courses of action for
economic agents. It is important to understand the blockchain heterogeneity
so as to better grasp what kind of socio-technical or socio-digital assemblages
they are, and what consequences those different types entail in relation to economic agency. Assuming the homogeneity of blockchains and not controlling for
their actor-network heterogeneity may lead to erroneous theoretical generalizations or empirically partial observations. The paper shows that blockchain
digital infrastructure defines two major types of actors: transactioners and
accountants, and argues that blockchains can be categorized based on how
their architectures define who can be active as transactioner or accountant.
Drawing on this distinction, the paper demonstrates that there are two types
of blockchain architecture: public and private blockchains. Furthermore, these
blockchains are diversified based on who can account for their transactions:
Open Accounting Blockchains and Closed Accounting Blockchains. In discussing the consequences of these four blockchain categories, the paper shows that,
without developing a nuanced understanding of the heterogeneity of blockchain
architecture, it is impossible to make sense of how blockchains work, let alone
what their consequences are. The paper ends by interpreting cryptocurrency
as data money and locating cryptocurrency ownership as the possession of an
exclusive right to transfer data privately in a public or private space, and by
showing that blockchains are digital actor-network platforms that make it possible to define and distribute these data transfer rights.6
The evolution of blockchains
When the Bitcoin blockchain was developed by an anonymous writer by the
name of Satoshi Nakamoto 10 years ago, its cryptocurrency was referred to as
‘electronic cash’, and the platform of its production and exchange was presented
6 Economy and Society
as a ‘peer-to-peer network’ without naming it a ‘blockchain’ (Brunton, 2019).
The terms block and chain never came together as one word in that paper.
Yet, this nine-page-long white paper was to introduce an economy whose capitalization would reach US$ 305 billion in less than a decade, surpassing the
market worth of Visa, the world’s largest credit card company by US$ 50
billion in December 2017.
One does not need cryptocurrency or blockchain to digitally represent money
or currency, and transfer them via internet. These transfers and representations
are as old as the times when financial intermediaries such as banks began using
computers. In 2008, the first blockchain of the world managed to produce and
transfer value without an intermediary in public. The mechanism looks
complex, but it draws on a simple principle of accounting. Imagine that Alice
sends US$ 1 to Bob. Alice’s bank withdraws US$ 1 from her account, and
Bob’s bank adds US$ 1 to his. The transaction appears in the double-entry
book-keeping system of the bank and is reported as part of aggregate accounting
data to the state for tax purposes. Alice cannot spend the same US$ 1 again, for
her account would physically lose it, and if she went to the bank to withdraw all
her money, she would end up having US$ 1 less cash.
Nakamoto proposed a way to transfer value, like the system explained above,
minus banks and states. Alice sends 1 Bitcoin (BTC) to Bob without going
through a formal financial institution; an attending problem is how to prevent
Alice from spending that 1 BTC again. This is a challenging difficulty to
address, because unlike difficult-to-forge paper or metal money, it is very
easy to copy and paste a digital representation.
Digital representations of fiat currency, or digital currencies, are still fiat and
categorically different from cryptocurrencies in two ways. First, they are not
data monies whose circulations or exchange draws on the transfer of exclusive
rights to send data without an intermediary’s supervision. Second, digital fiat
currencies, although lacking the physical paper representations, are still
minted and supplied by banks and states. Hence, what makes data money
unique is its novel treatment that prevents it from being forged, copied or
spent again, while at the same time ensuring that its transfer is not reversible
at will. Bitcoin blockchain developed a system to address this difficulty, generally called the double-spend problem and irreversibility of transactions.
Let’s say, Alice wants to send 1 BTC to Bob. This transaction proposal is
encrypted by sophisticated programs to make it a unique digital representation
that cannot be re-represented without a series of passwords. Then, this proposal
to transact 1 BTC appears on an internet network, where a community of
accountants see this digital proposal among hundreds of others around it.
These accountants then choose, for example, 500 of them and write them
down on a digital page called a ‘block’. If they manage to add this new page
to the Bitcoin digital ledger, the proposed transaction between Bob and Alice
is realized. Once recorded in the digital ledger, it is almost impossible to
change, alter, modify, or cancel this transaction, thanks to the protocol that
runs the system.

Why would someone volunteer to be an accountant of such a system, unless
she earns something from it? Nakamoto addressed this problem by giving a
digital thing that may be found valuable to any accountant who managed to
add one more page to the ledger. And this potentially valuable digital thing is
called a Bitcoin. What makes it valuable is not ‘an abstract and subjective
belief’, but its material utility in proving an actual service of value creation
and transfer without the necessary presence of a central formal institution or
intermediary.
In the beginning ‘the thing’ was 50 BTC, which represented some value to
the accountants that Nakamoto called miners. Until March 2010, BTC did
not have any significant monetary value. There was no BTC market, only scattered auctions here and there, with no market price to quote. However, with the
opening of the first digital currency exchange market in 2010 – that is, Bitcoinmarket.com, a now defunct intermediary institution designed for Bitcoin
exchange – the value of BTC began to pick up. Here, it is worth underlining
the fact that a development with the stated aim of disintermediation began to
be valued only after it contributed to the making of a new intermediary institution, a Bitcoin exchange market. Such an unprecedented valuation of
Bitcoin was also due, most probably, to the 2008 crisis that took down with it
much trust in conventional financial institutions. Ten months following the
emergence of the first Bitcoin exchange market, Bitcoin was traded for US$
1, changing the entire landscape of its accounting, because more and more
accountants could earn more by contributing to Bitcoin accounting process.
A currency issued and backed by no state had reached the value of a currency
issued and backed by the United States.
The Bitcoin protocol controls Bitcoin creation by four mechanisms: First, the
amount of Bitcoin per each mined block would be halved after every 210,000
blocks. In 2009, it was 50 Bitcoins, while in 2012 this number decreased to
25, and in 2016 became 12.5. The more miners the accounting system attracts,
the faster its rewards shrink. Second, one receives an automatic reward as soon
as one mines a block. Many miners compete for this; therefore, a chance event
also controls the number of miners who can receive the reward. The miner who
guesses a number that the protocol uses once, called the nonce, is given the right
to close that block, and only after this correct guess, that miner’s block is added
to the ledger. Third, the value of the cryptocurrency itself is in part controlled
by the protocol in a deflationary context, by fixing the number of Bitcoins to be
mined at 21 million. Finally, the protocol defines a transaction fee that can be set
as zero or more by the transactioner, which once exceeded US$20 million a day
on 21 December 2017, when a total of 1,496 BTC were paid to miners. A person
who wants that change the transaction speed is free to increase, or decrease it, all
the way to zero. Thus, after the 21-millionth Bitcoin, mining will only be carried
out with transaction fees.
Going back to our imaginary example, Alice, after attaching an attractive
transaction fee to her proposed transaction, has her proposed transaction
included in a block. As soon as the block is added to the ledger thanks to a
8 Economy and Society
successful miner, that 1 BTC (minus the fee) becomes Bob’s property. What if
Alice wants to spend again the Bitcoin she sent to Bob? She cannot, because
‘spending’ means transferring the right to send it to someone else, and
because Bitcoin is the right to send fixed and non-replicable data to someone
else privately in a public ledger; once sent and registered, that right has been
transferred to Bob for good.
Double-spending and irreversibility are enhanced by making every transaction public, without giving Alice and Bob’s real names. Imagine a magical
notebook: you write something in it, and this note pops up on everyone’s notebook and can no longer be altered as soon as the majority of owners of the notebooks accepts its validity. Even if you erase the note in your own notebook, it
will remain on record in others’ notebooks. The attempt to change the
ledger, and thus spend the same Bitcoin again or send it to someone else, is
so costly that Bitcoin blockchain users avoid it.
Following Bitcoin blockchain, various other blockchains were designed,
either independently constituted or constructed as a derivative of the Bitcoin
algorithm. Yet, with the emergence of the Ethereum blockchain, it became possible to send digital assets only if certain conditions were met, thus embedding a
new value in the computation itself. Buterin published the Ethereum blockchain
white paper, giving birth to the second-generation blockchains.
First-generation blockchains facilitated sending data, whereas second-generation blockchains made it possible to send data if certain conditions were met. In
other words, Ethereum allows embedding contracts into digital value and transferring a short computer program, thus changing the nature of accounting from
checking for value to checking for a working contract, or a program. Let’s say,
Alice decides to send Bob 1 BTC, but only if Carol sends Bob 2 BTC. This is a
conditional context: The transfer of value between Alice and Bob only happens
if a certain condition is met on the other end, which is the successful transaction
between Carol and Bob.
The outcome was groundbreaking in the sense that the advanced computer
language of the Ethereum blockchain rendered it possible to imagine value as
contract, and with minor and relatively easy alterations; others began to use
Ethereum as a framework to imagine new cryptocurrencies without building
new blockchains. Without changing the main logic of imagining value as a
right to send data, Ethereum gave birth to the big bang in the cryptocurrency
universe.
These second-generation blockchains continued to develop their infrastructural skills, so much so that the Truthcoin blockchain managed to include outof-chain conditions to be accounted for by smart contracts. Let’s say, Alice
sends 1 BTC to Bob only if the weather temperature in New York City is 35
Celsius or above. Obviously, the weather is not a blockchain event; it is what
coders call an ‘off-chain event’. However, the data generated by meteorological
sources can be coded into smart contracts to create off-chain world events to
trigger the realization of ‘in-chain contracts’, or making ‘oracles’, as coders
would put it. This new development facilitated the transfer of almost any
Koray Caliskan: Data money
9
financial off-chain instrument into blockchains, such as stop-loss-orders on
derivative contracts.
The opening of such a wide spectrum of options in blockchains led to imagining more complex transactional relations and infrastructure-making, giving
birth to the third-generation blockchains: blockchain architects have developed
systems that create an ‘interchain’ network, such as Aion, by putting mutually
exclusive blockchains with dissimilar computing protocols into contact and
transaction with each other (see Table 1).
As such an evolution took place, corporations and states also started to
develop their own blockchains, for there is nothing fundamentally ‘public’
about blockchain technology. Depending on one’s intentions, one can create
specific keys to lock or unlock relations in a blockchain, as this paper demonstrates in the third section below. However, paying attention to the evolution
of blockchain platforms into complex and structurally rich infrastructure, contributes to a more nuanced analysis of these infrastructures and the particular
ways in which they effect economic agency. To address this, one needs to
study the specificity of these architectures, by looking at the white papers
that construct them in the first place.
Cryptocurrency white papers at a glance
A white paper is a curious thing, stuck between science and investment. Emerging at the beginning of the twentieth century in Great Britain, white papers
originally presented a government’s position on a matter of controversy. Its
cover was white, hence the name. Almost one century after their emergence a
new type of white paper emerged, this time digitally. Like an architectural
plan of a building, white papers plan the making of a blockchain architecture.
With the publication of Nakamoto’s Bitcoin White Paper on the internet, it
became customary to write one for proposing a new cryptocurrency or blockchain. These white papers aim to fulfil three functions. (1) Persuasion: A blockchain used by no one is a chain with no valuable cryptocurrency. All groups or
individuals who develop a blockchain architecture should convince as many
agents as possible about the usefulness of its services. (2) Proving: Even
though people may find it useful in their economic lives, the blockchain architecture may not work. Thus, the white paper has to describe in detail, frequently
by mathematical modelling, the proof of its working. (3) Education: White

papers teach the ways of using their models, programming technique and framework of exchange. As a result, white papers not only understand and describe
a world of interaction, but also design and produce the very world that they are
depicting, thus forging new forms of performativity in late modern relations of
economization.
White papers usually open with a historical discussion of blockchains, and
without exception, with a reference to Nakamoto. Then, they move on to
describe the shortcomings of the state of the art, define a gap in practice, and
present a service that they can supply with their specific blockchain or cryptocurrency, followed by describing how the underlying protocol work. The
majority ends with a list – at times supplemented by photographs and biographies – of the authors, teams or advisors, in part showing how they have
been recognized as entrepreneurs, business administrators or academics.
Much like a scientific paper, almost all end with a conclusion and bibliography.
The average length of a white paper is 25.74 pages, with an average of 8,060
words. The shortest paper is a single page long, whereas the longest runs 62
pages, excluding appendices.7 The writers of 56 per cent of these papers
choose to remain anonymous (such as with no writer) or pseudonymous
(such as Satoshi Nakamoto), and these papers present cryptocurrencies that
carry more than 70 per cent of all cryptocurrency value in the world. It is a
telling irony that these white paper’s authors claim to address questions of
trust, but keep their identity secret.
Of all white papers, 44 per cent display the names of actual people, all with
working email addresses, LinkedIn entries and Twitter handles. On average,
a white paper is authored by 2.59 writers. None of the non-anonymous
writers of white papers are women.8 Of these papers, 59 per cent start with
an abstract, and on average they cite 14.60 publications in their bibliographies.
Of these references, 24.31 per cent are academic publications. Wikipedia is the
most commonly cited source in their bibliographies, appearing at least once in
26 per cent of white papers. Nakamoto is the most cited writer, referred to at
least once in 40 per cent.
Fourteen per cent display the publication place, either by mentioning a
company address or the place itself. Twenty-one per cent make their publication year visible. It is possible to learn the publication date of the rest with
a simple search engine, but authors chose not to make the date visible at first
sight. Of these white papers, 88 per cent came out between 2015 and 2018, following the publication of the Ethereum white paper. This supports the validity
of this paper’s observation that the emergence of the Ethereum blockchain
marked a big bang for cryptocurrencies.
A computational text analysis of the white papers shows that the most regularly used words fall into three frequency categories: The first incorporates
words used more than 2,500 times: ‘transaction’, ‘node’, ‘blockchain’, ‘user’,
‘network’, ‘token’ and ‘data’, making this set the centre of intellectual attention
in white papers that aim at proposing a new money form materialized in the
right to transfer data among users, accounted by nodes, and on a blockchain
Koray Caliskan: Data money
11
network. The second set brings together words that appear between 1,250 and
2,500 times, making visible the urgency of the papers’ writers to make visible
‘the new’, ‘novel’, and/or ‘original’ service and its main building blocks (literally) that these blockchains propose. The third group is composed of words
that appear between 500 and 1,250 times in white papers, focusing mostly on
the socio-digital aspects of these platforms that operate as markets as transaction
infrastructures working on a decentralized and orderly manner.
Analysing the simple frequencies is of limited help in understanding the
nature of the social scientific attention on which these white papers draw, for
it should not be a surprise to see the terms ‘transaction’, ‘node’, and ‘blockchain’
to appear frequently in white papers. Such a challenge can be addressed by supporting the analysis with a social scientific filter. Constructed on a calculation of
the supervised frequency distribution, this new analysis can draw on checking
the appearance of social scientific concepts that appear in a dictionary of social
science. Calhoun’s (2002) is the most cooperative dictionary with 1,800 entries
supported by a comprehensive bibliography. The rationale of my choice of this
dictionary as a filter does not only draw on its popularity and social scientific
care, but the transdisciplinary focus it deploys in social sciences that allow for
a robust socio-technical attendance.9
In terms of social science concepts, white papers use ‘finance’ more than 700
times, ‘economy’ more than 400 times and ‘social’ more than 350 times. Culture
(30 times) and politics (29 times) do not appear often in white papers.
Such a filter illustrates a different picture of these white papers that use
‘value’ most frequently, followed by ‘market’, ‘exchange’, ‘technology’ and
‘currency’, alluding that white papers deal with a market phenomenon that
is surrounded by the development of a technology for a currency exchange ecosystem. Furthermore, these five most frequently used social scientific terms as
plotted in Table 3 are the only ones that also appear in Table 2. ‘Money’,
‘rights’ and ‘credit’ also appear recurrently, usually in making visible the
function of cryptocurrency as medium of exchange, store of value and
unit of account. Infrastructure appears as among the most frequent used
space-related social scientific category, referring to the digital geography
that ‘nodes’, ‘actors’, ‘persons’, ‘consumers’ and ‘individuals’ relate to each
other.
Absences say much regarding priorities one can observe in the corpus of
white papers. For a development that is presented by its evangelicals as ‘revolutionary’, white papers do not frequently refer to any kind of revolution: The
term appears in only 1.3 per cent of the papers. Furthermore, freedom (35
times), equality (9 times) and liberty (one time) appear very rarely. In
terms of economic actors, white papers refer to ‘the individual’ as economic
agent more frequently than any other. Class is used frequently, but to
mean a cluster of variables or factors; ‘social class’ is used not even once.
One paper refers twice to gender in its disclaimer of liability section, and
another refers to it once, to mean ‘male’. ‘Trust’ is used very often, always
referring to the absence of the need for a third party or intermediary to

White papers imagine a world divided into two. They define the place where
blockchains operate as a ‘digital’ or ‘virtual world’, sometimes referred to as
‘crypto-world’ and ‘new world’. The other is called ‘the real world’ (in 47
papers) and physical world (in 4), referring to anything that is located outside
of the blockchain. The same bifurcation is at times constructed as ‘off-chain’
and ‘on-chain worlds’.10
White papers see ‘their own world’ as an architecture, infrastructure, or platform, very frequently using them interchangeably and to mean more or less the
same thing: a socio-technical arrangement that makes possible fields of action. A
quarter of white papers locate a fundamental time change during the time of their
publication, juxtaposing the ancien as either ‘traditional’, ‘old’, or ‘industrial’, vis a
vis the contemporary as ‘Information Age’. Three white papers mention gold as
the currency of the Industrial Age and Bitcoin as the gold of this age (see Table 4).
One should not expect scientific diligence and social theoretical discipline
from these white papers, for they do not claim to be scientific in the first
place, but draw on scientific research and argumentation to propose an economic service. Their aim is successful performativity, as they are forging a technical world with the intention of building a social interaction. The next section
describes the various types of the socio-technical infrastructure constructed in
these white papers and used on the ground today.
A taxonomy of blockchains
It is a myth to think that blockchains are free to use public ledgers that create
disintermediation via distributed bookkeeping carried out by anyone. Blockchains
are not necessarily public digital ledgers. There are many private blockchains or
even hybrid blockchains that bring together the possibility of private domain
accounting in a public setting.11 Blockchains are not necessarily free, either.
A transaction fee accompanies almost all Bitcoin transfers, even when the
person who proposes the transaction does not attach a transaction fee to her proposal: If she is performing a transaction on a cryptocurrency exchange, the
exchange usually adds a fee to its pool of proposed transactions to ensure that
its ‘customers’ get their transactions approved faster.
Blockchains do not create disintermediation in economic relations, as they
may or may not need conventional intermediary institutions, such as states or
14
Economy and Society
banks; however, they do create new intermediations (Zook & Blankenship,
2018). Blockchains do not disintermediate, but reintermediate. This is true
even for the Bitcoin blockchain, which is presented as the ultimate force of disintermediation (Tapscott & Tapscott, 2016). In 2018, 87.2 per cent of all Bitcoin
transactions took place in tens of thousands of cryptocurrency markets, none
written on the Bitcoin blockchain unless the buyer chose to ‘withdraw’ her Bitcoins from the exchange. One immediate consequence of this process of reintermediation is the near complete disappearance of anonymity, for a great majority
of exchanges require their clients to register with formal identification and
credit cards, thus introducing the cryptocurrency ownership to the visibility
of conventional accounting systems and networks that banks and states use.
Thus, cryptocurrencies are one of the driving forces of creating new intermediaries in economization relations, not a force erasing them. Finally, their
accounting or mining can be open to everyone; yet, in reality, much like in conventional accounting practice, only specialized accounting systems and experts
can operate mining operations for Bitcoin, after mobilizing important financial
investments. There is no free bookkeeping, even in the cryptocurrency universe. Thus, it would be erroneous to treat blockchain architectures as monolithic entities that structure economic relations in one way only. One needs to
be attentive to their types.
Since the emergence of the third-generation blockchains that allow building
in-chain markets and interchains, it became possible to move any conventional
economic sector to blockchains. Hence, it would not be practical to categorize
blockchains with reference to their services or products, since this would be
an exercise in categorizing all economies in their entirety, only this time
based on blockchains. Such attempts in popular representations of blockchains
have given birth to tens of different ‘types’ of blockchain that confuse rather
than help us understand them. There are also technical classifications of blockchains according to their various consensus mechanisms, such as proof of work,
stake, velocity, asset, activity, access, capacity, devotion, importance, elapsed
time, alienation, spending, reserve etc. One can propose categories based on
the nature of digital block-making. While very useful and legitimate for understanding the purely technical operation of chains, these taxonomies are less
effective in controlling for how economic agencies are imagined, mobilized
and equipped in/by blockchains.
This paper proposes a categorization that accounts for mutually exclusive
configurations of actor-network interactions in terms of transaction and
accounting practices in crypto-infrastructures. White papers propose two
groups of actors in all blockchains: Transactioners are those who use the
digital ledgers for realizing their transactions – such as Alice and Bob, who
transact the exchange of 1 BTC. Accountants are those who account for these
transactions by mining. These two are mutually dependent groups of actors.
Without accountants, no transaction is registered in the ledger. Without transactions, accountants cannot account for anything. Transactioners receive
accounting services from the accountants via the blockchain, and accountants
Koray Caliskan: Data money
15
receive cryptocurrencies as fees for their mining of the data and letting blockchains to use their computer hardware. A transactioner and an accountant
can be the same person, but from the perspective of their economic activity,
they perform different roles.
Blockchains vary according to the extent to which transactioners and accountants are excluded from or included in the blockchain infrastructure, regardless
of the nature of the transactions (such as value transactions or smart contract
transaction) or the nature of accounting (such as proof of stake or proof of
work). There are two forms of transactioner participation in blockchains: (1)
Private blockchains, such as that of Ripple, can block who may participate in
a certain blockchain. (2) Public blockchains, such as those of Bitcoin or Ethereum, are required by their protocols to include any actor to transact. There can
also be hybrid blockchains that provide their users with rooms for private or
consortium activity in their infrastructures. Third-generation blockchains are
generally equipped with these hybrid characteristics.
Blockchains can also block those who want to participate as accountant.
Closed Accounting Blockchains select those who can be active in its accounting
system. Open Accounting Blockchains permit any actor with the necessary
technical devices to serve as an accountant for its operations – that is, Bitcoin
mining is open to anyone who has the skills and devices to join. This does
not mean that in an Open Accounting Blockchain such as Bitcoin anyone can
be an accountant, an option that Nakamoto thought he wrote into the code.
Now, it is practically impossible to be a Bitcoin miner with a personal computer.
One has to invest in many and very expensive processors called ASICs.
However, this is not an infrastructural impediment in design, but an economic
cost that many actors cannot carry (see Table 5).
Each of these blockchain types draws on mutually exclusive infrastructural
qualities and implies varying socio-technical configurations of actor-network
relations. Open Accounting Public Blockchains cannot prevent any actor
from joining their transactional or accounting practices. These human actors
use material and digital devices to interact with the blockchain. Let’s say,
Alice wants to send 1 BTC to Bob; therefore, she is a transactioner who
cannot be prevented from using the Bitcoin blockchain, because it is a public
blockchain. Alice turns on her computing device, starts an application,
usually called a digital wallet, writes down the amount she wants to send to
Bob and then, with a click, the wallet sends a transaction request to the

blockchain network. Alice’s wallet is represented by an encrypted password
made up of 64 digits, and each digit is composed of hexadecimal characters.
These passwords are very difficult to guess and in reality, consist of hashes of
an even longer binary representation as can be seen in Figure 1.
One has to remember that all these accounting practices are performed by
computers with enormous hash power referring to a computer’s capacity and
speed in solving mathematical puzzles during a mining operation. These computers are owned by companies, and these companies hire workers to plug in
those computers, turn on the air-conditioning units to cool their processors,
clean around them, and fix and maintain them for smooth operation. Thus,
in reality we can argue that the Bitcoin’s Open Accounting Public Blockchain
brings together human transactioners and corporate computers in order to
build a value exchange architecture.
Open Accounting Public Blockchains, by bringing together transactioners
and accountants in an open and public digital space, thus function like states,
because they issue currencies; like banks, because they approve and account
for transactions; like marketplaces, because it is possible to buy and sell
tokens on their infrastructures. Yet, they have to play with time in order to
achieve contribution to their operations without permission. Because they do
not have a central authority to approve transactions and write them down,
they are slow and have to slow down in order to factor chance events into
their accounting system.
The problem of slow pace is addressed by Closed Accounting Public Blockchains, such as Cybermiles or Facebook’s proposed Libra. These blockchains
permit anyone to operate in their system as transactioners but decide who
may serve as an accountant for these transactions. These are blockchains
about which one has to be careful, because they want their data monies to be
used by all, but prefer their accounting system to be secretive and exclusionary.
Closed Accounting Blockchains do not allow chance and computing power
determine who can close a block, thus preventing the creation of a distributed
and decentralized mining or accounting system. Yet, they gain speed in their
operations. Their accounting systems can work faster than Open Accounting
Blockchains, and they need less electricity and thus hash power to be
operational.
Open Accounting Private Blockchains subcontract the mining of their transactions at the protocol level to anyone who would like to pursue mining. For
example, a union can construct a private blockchain if its members would like
to subcontract the accounting practice of their possible inter-union member
Koray Caliskan: Data money
17
transactions to a distributed system. In this Blockchain, only the union’s
members can pursue transactions, but they have to wait until their transactions
are accounted for by anonymous and public accountants.
Closed Accounting Private Blockchain, on the other hand, decide who may
be a transactioner and an accountant in their system. These Blockchains are
built by corporate entities who use blockchain technology to decrease their
book-keeping and transaction costs. All private and public banks are either
operating or developing a Private Closed Accounting Blockchain. There are
hybrid Open or Closed Accounting Blockchains which are a type of public
blockchain that can have a private space in their interaction architecture.
They can choose to operate on an Open Accounting mining system, or they
can determine a priori who may account for their transactions, thus choose to
draw on a Closed Accounting system.
Open Accounting Public blockchains are not public in terms of the ‘public
ownership’ of their means and devices of production and maintenance. An
Open Accounting Public Blockchain, such as Ethereum and Bitcoin, can be
developed and proposed to the public by a corporation, an individual, a political
party, or even a nation-state. There is no point of possessing a blockchain, for
they cannot be ‘owned’ like a piece of land or a webpage. In reality, blockchains
are networks of claims that distribute ownership rights among the actors that use
them; in other words, they are actor-network platforms incorporating agency
into digital frameworks. These private or public networks create the possibility
to attach non-digital value to the digital representations of owning the right to
move data.
Approaching blockchains as actor-network digital platforms that render possible the valuation and transfer of the rights to move data privately provides
social researchers with the theoretical capacity to describe and analyse the
rich universe of blockchains without imagining them as rigid devices or monolithic infrastructures that do things just because of their mere existence. In this
way, it becomes possible to observe under which conditions and how they
produce disintermediation and reintermediations, whether and how they can
compete with and replace the functions of banks and state, in how many
ways they empower and limit individual and collective action, and finally
whether they hold any revolutionary or reformatory potential at all.
Conclusion
Empirically studying the evolution of blockchain infrastructure and the white
papers of the most valuable 100 cryptocurrencies, this paper has proposed a
three-tiered evolution of four types of blockchain architecture, all bringing
together the socio-technical infrastructure of this novel digital ledger technology. The paper has shown that the categorical transformations that the blockchain infrastructure has undergone require social researchers to attend to its
dynamic renovation in studying the social and economic consequences of
18
Economy and Society
blockchain technology. Value exchange blockchains, like Bitcoin, are simple,
slow, yet effective platforms that make it possible to imagine and transfer
value in novel ways. Contract Exchange Blockchains provide their users with
devices to exchange simple computer programs that can operate as contracts,
thus making it possible to build new value or contract exchange platforms
within one blockchain.
Third-generation blockchains allow for the building of in-chain markets with
off-chain data flowing in them. This possibility permits blockchain architectures
to operate as markets themselves, not only registering individual transactions,
but also bringing together dynamic encounters of supply and demand, as
long as the underlying commodity can be represented digitally. Furthermore,
these new-generation blockchains render it also possible to construct relational
bridges between blockchains that operate on diverse protocols, opening a way to
build inter-chains. Drawing on this analysis, we can conclude the following:
First, it is impossible to pass universal and categorical judgments on how ‘the
blockchain technology’ works, since there is no single type of architecture
that can be located and evaluated. Second, blockchains’ dynamic evolution
poses a challenge for social researchers due to their potential to revise and
reform many institutional formations of contemporary economization relations.
Taking on such a challenge requires developing critical attention to the types
of blockchain architectures that stand on general blockchain infrastructure. Proposing an actor-based taxonomy, this paper has demonstrated that blockchains
are maintained by two major types of actor: transactioners and accountants.
Their agency, however, is structured in reference to the specific architecture
of the particular blockchain. Open Accounting Blockchains allow every accountant to perform mining at will, as long as the miner has the necessary devices,
such as ASICs. Closed Accounting Blockchains can choose which actor can
perform accounting, and to what degree. This option introduces a more centralized blockchain operation, by increasing the speed of transaction registration in
the chain.
Approaching blockchains from the vantage point of transactioners, the
paper has observed two types of architecture: (1) Public blockchains are
open to anyone for securely transferring private data, the movement of
which represents a kind of value. One does not have to be registered,
accepted, recognized or need permission to become a transactioner in such
a socio-technical architecture. (2) Private blockchains require permission or
acceptance to become a transactioner in their architecture. These permits
can be given to a consortium or an individual – in either case, this renders
the blockchain a private one.
This paper has defined blockchains as actor-network platforms that facilitate
the imagining and transfer of economic value, by digitally representing it as a
right to move data securely. In practice, blockchain infrastructure constitutes
a network of claims that provides actors with devices and competences to transfer ownership rights among each other. Yet, no one can own this platform of
rights, like a piece of land or a webpage, for once ‘owned’, the blockchain
Koray Caliskan: Data money
19
cannot operate as an infrastructure, even in private blockchains. Attaching nondigital value to the digital representations of owning the right to move data,
various types of blockchain architecture are supported and surrounded by formalized digital exchanges that also render it possible to exchange value off-chain
and then have it registered on-chain.
This paper aims to stimulate future research concerning the socio-technical
universe and implication of blockchain infrastructure. It sheds light onto
what kind of an actor-based taxonomy of blockchain architectures informs economic agency that began to exchange data monies, or rights to send fixed and
non-replicable data to someone else in a public ledger. These data monies are
categorically different from digitally represented fiat currencies or other
digital payment systems in the sense that they do not need the authority of a
bank, state or corporation in accounting, minting or controlling currencies.
Drawing on the materiality of financializing the right to send data, we saw
that data money’s materiality is historically and categorically different from
paper or metal money, or their digital representations.
Such an analysis, however, is limited in the sense that it doesn’t say much
about the practical working of the thousands of cryptocurrency exchange
markets created in part thanks to the seemingly disintermediating blockchains.
We still do not know in what ways these markets relate to and configure blockchain architectures, and how they work and interact with each other. We still
know very little about the social world of digital economic markets, their
prices, power asymmetries and valuation processes. Furthermore, social
research is far from identifying the potentially novel forms of performativity
taking place in blockchain and other digital infrastructures.
