        <p>Widespread digitalization of the modern society - the emergence of digital devices, the introduction of Internet of Things, the development of Big Data processing and other technologies result in new challenges. Not only industrial and corporate automation that has already been considerably covered by the legislation initiatives but also the digitalization of everyday life has started to constitute a critical infrastructure in the modern society. This largely happens because digital devices substituting traditional technologies owned by citizens are incorporated into corporate, financial and state business processes. For instance, citizens' devices are becoming the source of primary data for energy and utility companies. More opportunities for the direct interaction of automation solutions between themselves resulting in a controversial synergy effect have been emerging recently. The article addresses specifics of citizens' digital infrastructure in the light of critical infrastructure, in particular the necessity and special aspects of legal and regulatory framework and possible development trends of this functionality.</p>

      <title>1. Introduction</title>
      <p>
        Digital infrastructure of modern society becomes
critical for its functioning, which is reflected in the
legislation [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. Critical businesses are not limited to
finance, corporate and state regulation spheres. Digital
infrastructure formed and used by the citizens also becomes
critical nowadays. Equipment owned by individuals
becomes an element of global infrastructure affecting the
functioning of large systems.
      </p>
      <p>Very often personal automation solutions are necessary
extensions of corporate systems. For instance, the
shutdown of financial, communication or other subsystems
servicing citizens’ mobile devices can cause a collapse in
the modern society. Traditional, non-digital technological
solutions may either not function or solve only a limited
number of tasks. However, a massive failure of citizens’
peripheral devices also may cause critical implications. For
example, a modern finance system largely operates in
digital environment. Transactions, operations, analytical
functions are performed in an automated environment. In
case of unexpected failure of automated solutions,
including citizens' devices, the shift to previous “paper”
information processing technologies may not be possible
and result in overall collapse of the financial system. In the
article, we will address the issues of incorporation of
citizens and their devices into the critical infrastructure of
the modern society.</p>
    </sec>
    <sec id="sec-2">
      <title>2. The challenges of citizens’ modern infrastructure</title>
      <p>Citizens’ devices interact directly with each other on the
basis of certain contracts. These contracts are made
automatically and require special legal and regulatory
infrastructure. Smart contracts are a good example of this.</p>
      <p>Every person owns several “smart” devices that can be:
• programmed;
• used simultaneously in concerted manner;
•
•
updated or reconfigured (e.g. by the update of
embedded software);
replaced by a new device due to the low cost caused by
massive replication.</p>
    </sec>
    <sec id="sec-3">
      <title>3. Possible solutions</title>
      <p>When building society's digital infrastructure it is
important to take into account changes happening at the
personal level. Risks should be detected and prevented –
unauthorized access to IoT objects, phishing of personal
data, location tracking etc. In order to do so it is necessary
to have solutions enabling to prevent unauthorized use of
IoT infrastructure, and solutions allowing establishing
mutual trust between them and other personal digital
devices.</p>
      <p>Solutions for the diagnostic of unnatural or unexpected
behavior of IoT objects and prevention of these states either
by the user himself or automatically are highly
soughtafter. These solutions should be implemented technically
and must be automatically supported by legislative norms
and regulations.</p>
      <p>It is crucial to reasonably define areas of responsibility
for incorrect or fraudulent functioning of personal devices.
For instance, it should be clearly defined in the legal
framework who is responsible for the incident – the user of
the device, the owner of the device or infrastructure
interacting with the device, the manufacturer of the device
or software installed on the device or external intruder.</p>
      <p>In should be clear to everybody which actions must be
performed by conscientious users of an IoT device or a
system consisting of these devices to provide a sufficient
response in order to avoid liability for the damages caused
by these devices.</p>
      <p>Providing a widespread incorporation of digital
devices, including for instance IoT devices, there is a need
for the new methods to support social and economic
structure of the modern society.</p>
      <p>Every person in modern circumstances has to be
technologically-savvy, demonstrate a new level of
situational awareness and understand the behavioral culture
of digital society. This should be ensured by new norms and
regulations in the sphere of digital technology.</p>
      <p>Devices in the public digital infrastructure are explicitly
or implicitly registered; objects are being interconnected
and co-used. This connectivity and its usage is often
performed automatically. The examples of connectivity
between objects are – establishing ownership of an IoT
object by a particular person, content and usage rules set by
that person, object’s location registration and tracking of its
movements etc. Automated systems can provide
information about the objects connected with or interesting
to a certain person, about his movements or his usage
patterns for IoT objects. A new level of information
awareness has led to the emergence of new social and
economic challenges.</p>
      <p>In is not uncommon in digital infrastructure when a
person cannot detect risks arising out of the incorporation
of IoT devices, new means of communication and
processing of information, or assess implications of the use
of the new technologies. Besides, possible risks in digital
infrastructure tend to increase due to the development of
device technical characteristics and introduction of new
data processing tools.</p>
      <p>Many challenges arise out of the development of the
emergent properties in digital systems. These challenges
are associated, for example, with the integration of data
about the digital devices usage by a certain person and
accumulation of data history. For instance, it is possible to
collect data and use it implicitly with the Big Data
technologies. These methods allow to detect new links
between objects, e.g. to personify previously anonymous
information. The application of these methods may result
in the situation when data harmless for a user today may
jeopardize him in future if these data is somehow specified
or new data aggregation and processing technologies are
applied in unexpected ways.</p>
      <p>Thus, there is a need for scientific researches,
development and implementation of tools guaranteeing a
certain level of situational awareness for persons who are
not familiar with the specifics of surrounding digital
infrastructure, allowing to be efficient in a rapidly changing
digital infrastructure environment.</p>
      <p>Tools enabling situational awareness should be
implemented predictively, i.e. their emergence should
precede the development and implementation of new
communication features, IoT devices and systems based on
them. The new device development process should be
comprehensive, addressing not only technical and
technological aspects but also considering psychological,
social, economic and legislative factors.</p>

      <title>4. Legal environment around digitalization</title>
      <p>Preventive development of regulatory framework for
the application of digital infrastructure is crucial in modern
world.</p>
      <p>To implement legal restraints corresponding to the
requirements of the new digital infrastructure it is
necessary to use technologies adapted for the application in
digital environment, e.g. technologies that can operate
automatically. The use of smart contracts is the example of
the application of such technology. With the use of smart
contracts, it is possible to implement automated means of
communication, for example, for settlements between
elements of the IoT infrastructure.</p>
      <p>Smart contracts is a new, evolving technology that
requires conceptual research, technological improvement
of available solutions, and the development and adoption
of new norms and regulations. Let us discuss some
conceptual issues related to the use of smart contracts in
digital environment.</p>
      <p>
        The term smart contract is not standard. It does not fully
reflect the essence of the technology behind it. It actually
means not a smart contract but a form of formal contract
representation with the use of digital infrastructure that is
enough for preparation and execution of a contract in
digital environment. In [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ] it is suggested to use the terms
smart contract and automated (self-executing) contract as
synonyms. Besides, the term self-executing in authors’
opinion more accurately reflects the essence of this
technology. The term digital contract may be suggested –
it reflects the fact that operations with contracts using this
technology are incorporated into digital infrastructure one
way or another. Smart contract may not be executed as a
traditional document but still somehow enables the
execution of necessary arrangements in a particular
situation. However, as the term smart contract is the most
commonly used in literature, we will use it here.
      </p>
      <p>
        Technological implementation of smart contracts can
be different. The same requirement, for instance to have a
formalized form and automated execution of some
contracts can have different technological implementation
and apply different social and economic technologies.
Under the social and economic technologies, we mean the
combination requirement – technology that is used to fulfill
the requirement [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ]. The same requirement can be met by
different technologies; the same technology can be used to
meet different requirements.
      </p>
      <p>
        When talking about smart contract implementation it is
often meant the use of Blockchain technology. Many
authors consider Blockchain as a part of the technology
implementing smart contracts. However, others point out
that smart contract should be technologically- neutral [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ].
Now smart contracts often use Blockchain technology and
thus they are often considered as complementary
technologies [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ]; in future the use of smart contracts may
require the application of advanced technologies
guaranteeing data immutability at the execution of smart
contract. Differences and interaction specifics between
smart contract using Blockchain and a traditional contract
should be taken into account. There is an opinion that smart
contract fits into the existing system of legal documents and
becomes a one more semantic layer of a traditional contract
[
        <xref ref-type="bibr" rid="ref6">6</xref>
        ].
      </p>
      <p>
        The example of implicit smart contract implementation
when traditional documents are not produced at all is
automated taxy ordering system. One of the most
wellknown services of that kind is Uber [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ]. A person orders a
taxi for the price calculated by the system for a particular
itinerary. The price is calculated with consideration to
demand and traffic situation. Prepayment or funds
reservation is not needed. The driver that accepted the price
set for the trip provides the service, receives payment in
cash or by any type of cashless payments. After the trip the
driver and the user assess each other. Obviously, negative
assessments can be caused by unsatisfactory service.
      </p>
      <p>In this example, smart contract is implemented without
traditional documents. Correctness of communication
between parties is guaranteed by the automated system – if
one of the parties does not fulfill its obligations, it is fined
and the further use of service can be blocked. Technology
supporting data immutability with the use of distributed
ledgers is not needed in this case – the contract is short
term, mutual assessment and sanctions are done
immediately. Automated system enabling the service
operation arbitrates the parties.</p>
      <p>
        The issue whether a traditional contract should be
supplemented by a smart contract is being brought up in
literature [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ]. In our opinion, the example described above
demonstrates that at the current level of technological
development this is possible only in cases when contract
negotiations can be formalized. This allows to clearly
specify parties' rights and obligations, register in detail the
state of a contract execution and undoubtedly interpret all
possible ways of its violation. It may be expected that
further technological development will broaden the scope
of situations where it is reasonable to use smart contracts.
      </p>
      <p>Technologies similar to the described taxi ordering
service are becoming more and more popular and are used
for the provision of services with the help of digital devices
- smartphones and computers. These technologies
considerably change social and economic landscape of the
modern society. Thus, for example, they have
fundamentally transformed the taxi market – prices
decreased due to free competition, traditional taxi ordering
method with the use of a telephone in many cases became
an add-on to the described automated system. However,
operating principles require the development of legislative
regulation in order to eliminate potential problems.</p>
      <p>
        Summing up, we can state that the technological
implementation of smart contracts should be done
according to the following technological and legal
requirements:
• Impossibility to change a contract content without
consent of all participants, however, if such consent is
granted, the contract can be changed. Immutability of
contract’s content is often guaranteed by the use of
Blockchain technology; still, this is just one of the
possible options enabling smart contract content
immutability and its execution.
• Technological invariance. For example, when
processing technology is updated or changed for a new
one, available smart contracts should remain valid.
• Legally binding. The contract must be duly supported
by the norms and regulations in force guaranteeing its
execution by the parties involved and providing
protection in case of rights violation. However,
excessive regulation that impedes the development,
should be avoided.
• Compliance with regulations concerning data
processing procedures, for instance with the legislation
on personal data processing [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ].
• Verifiability and possibility to check the contract by the
parties.
• Resistance to fraudulent activities, such as hack of
software, insufficient information about parties to the
contract withheld intentionally with mercenary
intentions etc.
• User-friendly design of smart contracts, possibility to
present smart contract in a convenient form.
• Clear procedures on all stages of contract preparation
and execution.
• Possibility to combine digital and traditional display,
i.e. availability of software enabling to convert smart
contract into the format suitable for both automated
application and perception by people.
• No high requirements towards resources of the
infrastructure, possibility to scale the system processing
smart contracts. .
• Possibility to work bypassing intermediaries in the
process of contract negotiation and execution.
• Availability of interstate agreements on the
acknowledgement of contracts made by persons
belonging to different jurisdictions.
• Standardization of information processing procedures
with the use of smart contracts.
      </p>
      <p>
        Obviously, available smart contract implementation
solutions do not meet all these requirements. This
technology is still in the process of methodological
interpretation and development. However, it is integrated
by both commercial enterprises and state regulation
authorities of some countries. In the United States, the use
of smart contracts is still regulated on the states level [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ].
      </p>
      <p>
        In Russia the use of smart contracts and related
technologies is still not enough regulated with regards to
legal framework. However, the adoption of some relevant
norms and regulations is expected in March 2020 [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ].
      </p>
      <p>Legislative framework around smart contracts should
be implemented considering the widespread use of
automated devices. It should be developed taking into
account smart contracts use cases in ordinary routine
situation in order to guarantee that the new means of
communication are understood by a general user, that they
do no cause discomfort and tensions in society.</p>
      <p>It may be assumed that the legal system supporting
digital environment will function similar to the traditional
legal system because despite of new means of life cycle
implementation it attends to the same subject domain and
supports the same activities but with the help of a new
technology. For example, a promising IoT infrastructure
will became a formalized and programmed subdomain of
the traditional infrastructure. In the context of IoT
infrastructure smart contracts may include for instance the
following content:
• Service Level Agreements (SLA) in a special format
allowing to control and assess the fulfillment of mutual
obligations by devices and their owners at the
technological cooperation.
• Settlement and cooperation terms in a broader context
not covered by SLA .
• Requirements towards service access, formats, volumes
of data exchange and other parameters specific to the
system consisting of certain devices.</p>
      <p>The contents of smart contracts should be available for
the wide application by users who do not have professional
experience in digital technologies. It is crucial to address
the challenges of interface usability and use cases for the
implemented technologies.</p>
      <p>Figure 1 demonstrates types of smart contract users and
the goals they plan to achieve using this contractual
instrument. Citizens get a convenient automated tool to
process personal information. The state controls and
regulates the sphere in order to minimize risks for citizens
and social and economic system in general. Besides, the
state provides infrastructure services enabling smart
contracts implementation. These include up-to-date
manuals and classifiers enabling standardization of smart
contracts content.
Businesses suggest a smart contract business model of
a certain type and implement it. Throughout the life cycle
of the implemented system businesses strive for
profitability of the system, provide its modernization and
development.</p>
      <p>Design, operation and technological development of
this type of smart contract providing sufficient SLA for the
chosen business model is supported by technical and
technological solutions. The developed software is focused
on citizens; they should understand clearly how to work
with smart contracts. Special attention is paid to the
usability and friendliness of the system interfaces.</p>
      <p>Progress in the humanities and natural science is used
for the research of smart contracts development tendencies,
of best ways to incorporate this technological trend into the
social and economic system; it also helps to address the
challenges of technology performance. Ensuring
immutability of smart contract content providing sufficient
operation flexibility is one of these developing trends.</p>
      <p>
        Digital infrastructure object features related to smart
contracts such as those of IoT devices can be considered as
a type of virtual assets in addition to other types described
in [
        <xref ref-type="bibr" rid="ref12">12</xref>
        ].
      </p>
      <p>It should be noted that objects of the legislative
framework have its own life cycle – from the adoption to
the termination or change for new objects. Life cycle of a
norm or a regulation is shortening due to the rapid
emergence of the new types of digital infrastructure
objects, change in their functionality during operation. The
acceleration of changes affects the use of digital
technologies in everyday life. Emergence and rapid general
adoption of digital technologies by social and economic
system created a new situation in the society impending the
loss of control and collisions due to the development of
unexpected emergent features. Preventive development of
legislative framework, regulation of digital technologies
usage will allow eliminating possible negative situations.</p>

      <title>5. Conclusion</title>
      <p>Digital devices owned by citizens have become a
critical element of infrastructure in the modern society.
These are personal communication devices, e.g.
smartphones, and IoT objects, e.g. home management
solutions, utility resources consumption solutions etc.
Traditional communication channels and a significant part
of object environment are substituted by functionally
similar digital devices. New types of violations and
technological risks arise along with positive results.</p>
      <p>In these conditions, it is essential to preventively
implement new legislative framework, new technologies
such as smart contracts that meet the requirements of the
changed environment and allow to provide effective
management mechanisms for the society and eliminate
negative situations.</p>
      <p>It is also needed to develop and implement norms and
regulations that precede the development of new
technologies and allow to guarantee efficient operation of
social and economic system in new conditions.</p>
