1) Tokens can serve as new mechanisms to govern blockchain platforms by functioning as incentive mechanisms, access mechanisms, and coordination mechanisms. As incentive mechanisms, tokens can reward contributions and discourage bad behavior. As access mechanisms, tokens can be used to access platform services and functionality. As coordination mechanisms, tokens can define and coordinate the behavior of different actors. 2) Tokens influence the development of blockchain platform ecosystems by creating new participation structures and network effects. They allow users to participate in a platform's success and better align incentives. They also leverage new kinds of "token network effects." Further, tokens can help create self-governing and organic ecosystems through standards and democratic processes. 3) The study provides theoretical and

Tokens : A Brief History
• According to the Cambridge dictionary
tokens denote “a round, metal or plastic
disk which is used instead of money in
some machines”. Hence, tokens can be best
understood as a voucher or a gift card that
can be used to consume a variety of
services within a certain context (e.g. a
shop, a fair, a casino, a vending machine or
a platform)
• Tokens originally emerged in the fields of
behavioural economics and psychology with
the aim to modify behaviour of
institutionalized individuals (Kagel, 1972;
Winkler, 1971).

Types of Tokens – Utility Tokens vs Security Tokens
© 2014 | Nikolaus Lipusch
• Utility tokens are tokens that entitle its holders to access a
platforms service or application. Their main purpose is
utilitarian. e.g. Filecoin
• Security tokens are tokens that give their owner the right
to implement his investment interests. It may be the right
to participate in a legal entity, capital, profit e.g. tZero

Types of Tokens – Native Tokens vs App Tokens
© 2014 | Nikolaus Lipusch
• Native tokens are tokens that are inherent to the
blockchain and that are used to access the blockchain (in
particular they are used to pay for computation on the
blockchain). E.g. Ether
• App tokens are tokens that used in the applications that
lie on the top of the blockchain. They are used to acess a
certain application that is build on the blockchain and are
interoperable with the native token of that blockchain. E.g.
Numeraire

Theoretical Background – Platform Boundary
Resources
- Boundary object, which is an artifact plastic enough to cut across multiple
social worlds by providing enough structure to support several parties and
their employed activities within separate social worlds (Bergman et al. 2007;
Star and Griesemer 1989).
- Platform boundary resources allow third-party developers to build
applications on top of the software platform (Ghazawneh & Henfridsson 2013).

19. 23
Theoretical Background – Functions of Platform
Boundary Resources
• Platform Expansion
– E.g. Application Programming Interfaces (APIs), Software
Development Kits (SDKs)
• Platform Control
– E.g. appliction review processes, license agreements
• Other Functions: monetizing, resourcing, securing etc. (see
Ghazawneh & Henfridsson 2013)

Case - Ethereum
• Ethereum was launched by Vitalik Buterin in 2015
• Vitalik was a former bitcoin developer who created
Ethereum with the idea in mind to extend the
functionality of the blockchain (single purpose
blockchain)
• Ethereum constitutes a multipurpose platform that
consists of a blockchain and decentralized applications
(so-called DAPPs) that run on top of this blockchain
• Turing-complete programming language
• Smart contracts stipulate conditions for an application
to run (i.e. applications can be fully automated)
• Tokens with multiple functionalities

23. 28
Case – Ethereum Architecture
At the basis of Ethereum are 2nd layer protocols that can
be used to develop and run a variety of decentralized
applications known as DAPPs

24. 29
Case – Ethereum Architecture
The interactions between different layers and actors of
the platform are governed by tokens that are fungible (i.e.
they are interoperable)
• Ether = Ethereum's native token
• App tokens: e.g. IDEX, Bancor, Augur, Numerai, Cryptokitties

Ethereum‘s Growing Strategy
• July 2014/ Ethereum conducted an ICO
• 42-day pre-sale in which 60,102,216 Ether tokens were
sold to investors with a corresponding value of US$
18,439,086.
• July 2014 – May 2015/ Ethereum created
several endowment pools and programs
to reward early platform contributors
• e.g. DEVGrants Programm (US$ 1000 to US$10000 to
support Ethereum projects)
• e.g. Olympic testnet (25.000 Ether for users who managed
to break the network)
• July 2015/ Etherum Frontier Release
• Ethereum created its first mining network (under the
Frontier release) that allowed users to earn tokens by
providing their computing power to execute smart
contracts and to secure the network.

30. 37
• February 2016/ Ethereum Homestead
Release
• Ethereum introduces ist ERC20 token-standard which
allows the broader masses to create their own DAPPs on
the network
• Feb. – June 2017/ Several Exchanges
adopt Ethereum
• eToro and AVATrade list Ether on their exchange
• The Ether prices climbs to US$ 400 on June 2017 (i.e.
+5001% since Jannuary 2017)
• June 2017/ Broad adoption of Ethereum
ERC20 token standard
• e.g. Brave manages to collect US$ 35 million for its
Ethereum-based webbrowser.
• e.g. Bancor manages to $135 million worth of Ether to built
a decentralized market maker
Ethereum‘s Scaling Strategy

31. 38
• January 2018/ Ethereum hits all-time high
• 13.000% increase in value since Jannury 2017

Controlling Capabilities
• Using tokens (e.g. proof of
stake) as staking
mechanism to discourage
unfaithful behavior. e.g.
Miners (i.e. users) who
validate trustful transactios
earn more tokens, miners
who validate untrustful
transactions lose tokens
Expanding Capabilities
• Using tokens to expand
ownership in the platform
thereby encouraging app
development e.g. platform
developers can issue
security tokens to grant
ownership in the platform

Results – Tokens as Incentive Mechanism
Token mechanisms can help to incentivize good work and to
disincentivize bad work

37. 45 © 2014 | Nikolaus Lipusch
Results – Tokens as Incentive Mechanism
Token bonding curves can be used to attract early users – early
investments are rewarded to a higher degree

38. 46
Controlling Capabilities
• Using tokens as access
hurdle to weed out free
riders and to attract
committed users e.g. users
have to either buy in or to
fulfil some work to earn
some tokens and hence be
eligible to the platform
services
Expanding Capabilities
• Using tokens (i.e. set of
functions inherent to token
standards) to define and
access new platform
functionality e.g. app
developers can create their
own tokens to monetize the
development of their
applications (ERC20 token)

Results – Tokens as Access Mechanism
To elicit a transaction on Ethereum a User has to pay Gas i.e.
Etherums internal unit of account

40. 48
Controlling Capabilities
• Using tokens (i.e. token
standards) to clearly define users
scope of action e.g. by using the
ERC223 token standard users are
prevented to transfer their tokens
to a contract that does not allow
tokens to be withdrawn, thereby
protecting their tokens from
getting locked in.
Expanding Capabilities
• Using tokens (i.e. set of token
standards) to guarantee
interoperability and fungibility
between different types of
tokens/applications e.g. using
the ERC20 token standard
enhances a user’s ability to
interact with other tokens and
applications and hence to better
utilize the ecosystem

Results – Tokens as Coordination Mechanism
Token mechanisms that help to define and coordinate
behavior of different platform actors.

41. 49 © 2014 | Nikolaus Lipusch
Results – ERC20 Token Standard
The ERC 20 Token Standard contains six functions that define
a users scope of action when creating his own tokens.

RQ2: How will these platform
boundary resources influence the
development of blockchain
platform ecosystems?

43. 51
Tokens as new kind of platform participation
structures
• The relationship between the platform owner and third-party
developers is partly reversed since developers can participate
in the platforms success through equity.
• New more symmetric partictipation structures (Nassim
Nicholas Taleb, 2017)
• Result: Users are remunerated in accordance to the actual work
they are doing or the risk they are bearing (i.e. more
meritocracy)
• Better alignment of incentives between different actors of the
ecosystem
Future Research: How can these participation
structures be used to strategically govern
platform innovation?

44. 52
Tokens as a way to leverage new kinds of network
effects
• Traditional network effects
set in as the application
value of the platform
increases.
• Token network effects
denote a new kind of
network effect that bridges
the low user participation
at the begininning of the
platform creation.
Future Research: How must tokens be designed to create these
new kind of token-network effects? How do the different kind of
network effects created through tokens interact with each other?

45. 53
Tokens as a way to create self-governing and
organic ecosystems
• Tokens introduce a new form of clan control (clan control =
shared and values and beliefs)
• Ethereum Improvement Proposals (EIPs) allow users to come
up with their own token standards. Hence they can formulate
their norms in the form of code.
• Hence, tokens allow a much more democratic process in
defining community norms thereby resulting in truly self-
governing ecosystems
• Interoperability of tokens allow more ad-hoc and organic
evolvement of new communities
Future Research: How effective are tokens as new forms of
clan control to facilitate platform control and innovation?
