      <title>1. Introduction</title>
      <p>
        In recent years, blockchain technology has
become one of the most researched and
interesting areas of innovative development.
However, the emergence of new technology and
an attempt to apply it in the activities of
enterprises require the modernization of the
accounting system. The practical experience of
implementing blockchain solutions for
accounting and auditing demonstrates the
complexity of regulatory regulation in this area.
However, increased competition and global
market dynamics are forcing companies to pay
attention to new technologies and consider their
application, which requires the formation of a
clear regulatory position about such
technologies [
        <xref ref-type="bibr" rid="ref1">1, 2</xref>
        ].
      </p>
      <p>The relevance and prospects for the
implementation of blockchain technology in
accounting and auditing in the modern world are
discussed both in scientific research and in the
corporate environment. A blockchain, or chain of
blocks, creates an extremely reliable system of
records that can change the way accounting and
auditing are conducted. Blockchain solutions can
improve collaboration between stakeholders
and reduce the cost of transactions, as well as
allow for the creation of complex financial
instruments based on smart contracts. From a
stakeholder perspective, blockchain can enable
more reliable auditing of financial statements,
detection of fraud, and greater confidence in the
accuracy of information [3, 4].</p>
      <p>The prospects for implementing blockchain
in accounting and auditing are broad. They
include automation of accounting processes, in
particular through smart contracts,
simplification of internal and external control,
increased information availability, and the ability
to verify data in real-time. Therefore, research on
the peculiarities of using blockchain technologies
in accounting is relevant.</p>
      <p>The purpose of the study is to substantiate the
theoretical provisions and develop practical
recommendations on the specifics of using
blockchain technology in accounting.</p>
    </sec>
    <sec id="sec-2">
      <title>2. Theoretical Background</title>
      <p>The current state, prospects, and possibilities
of applying blockchain technology in
accounting are disclosed in the works of many
scientists. The basic concepts of blockchain
were introduced by Satoshi Nakamoto in
Bitcoin [5]. He proposed a distributed ledger
technology that tracks and maintains a
tamper-proof record of transactions in a
decentralized network. Essentially, it is a
unique database system that is created,
replicated, synchronized, and maintained by
all participants in a decentralized network.
Blockchain operates in a decentralized
peerto-peer network to verify and store all
transactions in a consensus agreed by all nodes
in the network, without any central authority
to verify the transaction (as in the case of an
intermediary). All completed and confirmed
transactions are recorded on the distributed
ledger in a verifiable, secure, and transparent
manner, along with a timestamp and other
details. In this way, the exchange of tangible
and intangible data and assets between
participants can be digitally recorded. Each
stakeholder maintains a copy of the
synchronized ledger, preventing a single point
of system failure or data loss. When changes
are made, such as the addition of a new block,
all copies on the network are updated
simultaneously and entries are recorded in all
ledgers at all times. These changes are saved
into blocks that create a chain where the block
is linked to the previous one by storing its hash
(unique data displayed from a given block).
Fig. 1 shows the fundamental chain
architecture of the blockchain network.</p>
      <p>Except for the first block (genesis block),
each block has its hash as a unique identifier
that includes the previous block’s hash. This
creates a chronological chain. In addition, the
hashing mechanism provides increased data
security. Typically, a block stores a set of
transactions with time stamps that
stakeholders in the network confirm. Once a
consensus is reached, the block is accepted and
stored by all parties in the blockchain and
cannot be changed. Thus, the trust and
transparency of transactions between
companies have significantly improved.</p>
      <p>Blockchain technology has many unique
features that allow for the creation of a
verifiable, secure, transparent, and immutable
distributed ledger, the main characteristics of
which are summarised as follows:
1. Universal exchange of values: Blockchain
provides a secure and efficient platform
for recording transactions regarding
intellectual property rights, provenance
of services and goods, ownership of
assets, cryptocurrency exchange, etc.
provides secure and verified data for all
network participants. Thus, the entire flow
of transactions is fully transparent, and
assets and data can be transferred
between multiple companies quickly and
efficiently.
3. Decentralized architecture: the ledger is
decentralized and stored in all nodes (i.e.
in separate stakeholder databases) of the
network, and its failure at a central point of
the infrastructure is impossible. Thus, it
contributes to a reliable network that
improves the quality, reliability, and
availability of services and information.
4. Logically centralized: A blockchain
network behaves as a logically centralized
system with only one transaction record
that all participants share.
5. Data transparency: blockchain technology
allows you to create a highly transparent
network that all stakeholders can see
anytime. This significantly reduces the
likelihood of illegal transactions.
6. Immutable data: once a block with a set of
transactions has been verified by
consensus and saved in the chain, the
recorded data cannot be changed.
7. Improved data security: blockchain
technology uses asymmetric cryptography
and digital signature algorithms to ensure
data security and individual identification.</p>
      <p>A typical permissioned blockchain follows a
similar data flow as shown in Fig. 2, where a
signature is attached to the transaction, which
is then sent or broadcast to the network and
added to the block. Once the block is verified,
the transaction is permanently stored in the
chain. A permission blockchain differs from a
permissionless blockchain in how blocks and
transactions are verified. To improve
performance and reduce latency, most
permissioned blockchain networks deploy
efficient consensus protocols that nodes use
for verification.
Many blockchain platforms have different
consensus algorithms, development tools, and
programming languages.</p>
      <p>
        Accountancy professional bodies, namely
the ICAEW, the Association of Chartered
Certified Accountants (ACCA), the Chartered
Institute of Management Accountants (CIMA),
the Chartered Institute of Public Finance and
Accountancy (CIPFA), and the International
Federation of Accountants (IFAC), all
published reports on their websites relating to
blockchain technology. For example, Deloitte,
EY, KPMG, and PwC have led the initiative to
integrate blockchain into their business to
meet clients’ changing needs for blockchain
transactions [8]. Accordingly, Deloitte created
its Rubix division and launched a
plug-andplay blockchain product [9]; EY introduced a
blockchain analyzer platform to support audit
team data reconciliation; PwC released
cryptocurrency audit software and updated its
Halo audit tool; and KPMG is partnering with
Guardtime, Microsoft, R3, and Tomia to create
blockchain-based services [
        <xref ref-type="bibr" rid="ref3">10</xref>
        ].
      </p>
      <p>The blockchain economy is closely related
to such concepts as tokenization, ICO (Initial
Coin Offering), and smart contracts. The use of
these elements will drive changes in the
existing economic system. Tokenization is the
conversion of a physical asset into a digital
format. This allows the owner to manage the
asset directly rather than resorting to
intermediaries or third parties. Technically,
tokenization is available for any asset or
intellectual property and knowledge of an
individual. Using tokens aims to provide most
business processes with transparency, speed,
accessibility, and cost reduction.</p>
      <p>Many people believe that cryptocurrency
and tokens are identical concepts. They are
similar but not equivalent. Tokens differ from
cryptocurrencies in the following key ways:
• Are issued by a private company or
organization.
• Are not used for payment on other
platforms.
• Do not replace fiat money.
• Cannot be obtained through mining.</p>
      <p>Tokenization is the basis of an ICO or initial
coin offering. To obtain investment for a
project, tokens that give investors rights to a
service or product are sold. ICOs are an
excellent way for startups to get funding
without venture capital. In return for the
investment, founders do not need to transfer
any of their shares in the company to third
parties. At the same time, investors can be
professionals and ordinary people. Without an
ICO, they would likely be unable to invest in the
project.</p>
      <p>The ICO process is similar to crowdfunding.
However, while fans receive products or just
pleasant bonuses in exchange for their
investments in the latter, the value of tokens
purchased at an ICO can increase tenfold over
time. That is why these coins are often bought
for further speculation rather than to use the
rights to the product.</p>
      <p>Singapore hosted the fourth largest ICO,
Huobi, which raised $300 million. Elsewhere,
Switzerland hosted six investment projects in
the top 15 campaigns. HDAC (No. 5) raised
$258 million, Tezos (No. 7) brought in $232
million, Sirin Labs (No. 8) received $158
million, Bancor (No. 9) brought in $153 million,

Polkadot (No. 11) received $145 million in
investment, and DAO received $143 million
from sponsors.</p>
      <p>Table 1 shows the structure of ICO projects
by application area; as you can see, most of
them were related to blockchain infrastructure
development.</p>
      <p>Another element related to blockchain
technologies is smart contracts, which are
essentially algorithms that perform
conditional actions: if action x occurs, then
action y is performed. Smart contracts allow
you to automate processes and ensure the
fulfillment of previously established
agreements. The terms and conditions set out
in a smart contract must be changed or
enforced. Such contracts have various uses,
such as elections, trade, and taxation.</p>
      <p>The fulfillment of a smart contract depends
on compliance with the terms and conditions
specified in it. For example, the rights to the
sold property are transferred automatically
only after the owner receives the amount
specified in the contract. The security of such
contracts is ensured by storing them in a
decentralized registry in an encrypted form,
but only if no errors are made in creating smart
contracts.</p>
      <p>
        Blockchain technologies may become the
backbone of the economy in the future.
Creating a decentralized financial system that
intermediaries, commissions, the state, and
corruption cannot influence is possible.
However, in practice, building such a system
will be a challenge. Banks and corporations are
now developing solutions based on blockchain
technologies themselves. For example, Google
is working on a blockchain to improve the
security and reliability of user data. The
Alibaba Group conglomerate is actively
working in blockchain technologies, and two
subsidiaries have even been set up to develop
software and study blockchain in supply chains
[
        <xref ref-type="bibr" rid="ref5">12</xref>
        ]. Banks are also implementing blockchain
solutions to organize and conduct their
business. For example, the British Barclays has
joined the blockchain consortium founded by
CLS Group, where participants are working to
create a decentralized competitor to the global
SWIFT payment system for fast and secure
transfers [
        <xref ref-type="bibr" rid="ref6">13</xref>
        ]. In 2017, 12 Chinese banks,
including state-owned ones, integrated
blockchain solutions. In 2018, the Spanish
bank Banco Bilbao Vizcaya Argentaria (BBVA)
issued the world’s first loan using a private
blockchain [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ].
      </p>
    </sec>
    <sec id="sec-3">
      <title>3. Results</title>
      <p>The analysis suggests that if states and banks
continue to create and integrate solutions
based on blockchain technologies, the current
system will change but will not become
decentralized and independent.</p>
      <p>Ideally, the formation of a blockchain
economy will lead to:
• Reduction of corruption and bureaucracy.
• Development and implementation of
innovative management methods.
• Ensuring transparency of transactions.
• Simplifying and reducing the cost of
financial transactions at the international
and local levels.
• Creation of a global independent
cryptocurrency.
• Creating opportunities for business
investment for everyone.
• Liberation from the control of the
centralized banking system.
• Introduction of a secure transaction
system based on smart contracts.</p>
      <p>The factors that hinder the development of
the blockchain economy may include:
• Lack of a well-developed regulatory
system—the industry, even in developed
countries, suffers from legislative
uncertainty.
• High volatility of cryptocurrencies,
attracts speculators to the industry and
causes dissatisfaction among regulators.
• Lack of understanding or interest in
technology, and development is possible
only with the participation of all
stakeholders.
• Impossibility of implementing the tasks
set in a short time without the help of
states and banks.
• High level of fraud in the ICO sector,
which may lead to a ban on the use of this
method of attracting investments.
• The use of cryptocurrencies as a savings
or speculative asset should become the
new money of the blockchain economy.</p>
      <p>For systemic economic processes, blockchain
technology is a way to switch to a decentralized,
transparent system and reduce the bureaucracy
associated with control regulations. Blockchain
technologies can be used to build a new financial
system and eliminate transaction intermediaries.</p>
      <p>The use of blockchain technologies can be
considered not only at the macro and mega
levels. Blockchain technologies will help
optimize and improve many processes at the
micro level. For example, a company can build a
motivation system based on blockchain. To do
this, develop a DApp solution (Decentralised
application) and add a token with the necessary
functions and characteristics. Tokens are not a
currency because they have value only within the
company.</p>
      <p>Nevertheless, the management system
allows the company to set the rate. The token
has an actual monetary basis, allowing
managers to control employee distribution
easily. The rate depends on the business’s
success, so tokens cross between money and
shares. When an employee receives such a
token, he or she has a different attitude to
implementing the plan. If successful, both he or
she and the company will benefit as the token’s
value increases. The versatility of blockchain
technologies allows you to attach any object to
a token—glasses, goods, services, or a voice.
This principle is a form of non-financial staff
motivation, which implies a specific list of
benefits that employees demand.</p>
      <p>The use of such a system offers significant
advantages. First of all, blockchain
technologies have advantages over banking
systems: the continuity of the system ensures
that any transaction is completed in the
shortest possible time, without failures,
breaks, or days off. Employees can freely
dispose of their earned tokens. However, the
main advantage of a blockchain-based
incentive system is a significant increase in
KPIs (key performance indicators). Everyone
will want to test the new system with their
hands, and getting the coveted tokens directly
depends on the quality of work. To prove
themselves positively, employees will start
generating new ideas and increasing their
productivity in the workplace. The bonuses
and benefits program should consider their
different needs and be flexible to ensure that
employees are properly motivated. Within an
individually set limit, each employee chooses
the benefits they like from a general list. A
distinctive feature of the solution is the
decentralized setting of limits: specific
categories of employees do not automatically
receive the same limits; they are set
individually for each employee, according to
their performance. More flourishing and
efficient work gives the employee more tokens
in the virtual wallet and, accordingly, access to
more rewards. It is important to note that the
company’s position or length of service does
not play a role, as every employee can prove
themselves in their work. The coefficient of
token accrual depends on the quality of the
work performed, and the evaluation criteria
are prescribed in advance in a publicly
available document.</p>
      <p>This incentive system has several
interesting aspects. Firstly, there is a currency
exchange rate. Its direct dependence on net
profit will stimulate better teamwork. For
example, the quality of communication
between departments will improve
significantly, as the conclusion of a deal may
depend on the timely receipt of the
information. Secondly, the token accrual rate
will significantly increase the quality of work
performed. Thirdly, the use of smart contracts
will make the whole process more transparent:
no one will be able to doubt the fairness of the
token accrual.</p>
      <p>Despite legislative obstacles, blockchain
technologies are gradually being introduced
into production processes and social life,
forcing the avoidance of outdated technologies.
Their revolutionary and explosive nature and,
at the same time, their adverse side are hidden
in a distributed public register that belongs to
no one and can be used by anyone.</p>
      <p>Legislation requires mandatory publication
of financial statements (for joint-stock
companies, banks, insurance companies, and
enterprises of public importance). Regular
disclosure of financial statements is required,
including balance sheets, income statements,
cash flow statements, statements of equity, and
notes to the financial statements. To maximize
their interests, management may mislead users
of information by manipulating accruals,
structuring transactions, and disclosing false
information. The reliability of the published
financial statements and notes is, to a certain
extent, guaranteed after the audit. However,
third-party users of the information cannot get
acquainted with the “real” transactions and
accounting processes of the company. Users
cannot obtain a complete, accurate, and timely
understanding of a company’s financial
position, operating performance, and cash flows
by reviewing the financial statements alone.</p>
      <p>
        The blockchain records and verifies
information in a decentralized way. The
process does not require authoritative
intermediaries, and blockchain technology
ensures the information is transparent, secure,
and protected from interference. As a result,
blockchain has a great potential to increase
trust between market participants [
        <xref ref-type="bibr" rid="ref8">15</xref>
        ], which,
in turn, the use of blockchain technology in
financial accounting has the potential to make
the accounting process of firms transparent,
improve the quality of external reporting
information and effectively reduce information
asymmetry between firms and external
investors.
      </p>
      <p>The application of blockchain technology in
accounting includes two aspects. On the one
hand, listed companies disclose accounting
information on the blockchain. Companies
publish source documents of transactions and
events and add payment fees and accounting
policies and methods embodied in smart
contracts to the accounting blockchain. Once
the smart contract is set up, if the firm chooses
to change it, all changes will be tracked on the
blockchain.</p>
      <p>On the other hand, as blockchain nodes,
various stakeholders will engage in
competitive mining and promptly record and
verify the information submitted by the
enterprise in a new block and then transmit it
to the blockchain network. Institutional
investors with technical and financial
advantages are more likely to become
blockchain nodes, as, in addition to the
rewards of mining blocks, they are also
motivated by an information advantage with
early access to corporate information. In
addition, counterparties such as auditors and
lawyers are also likely to become nodes on the
blockchain. Auditors can check source
documents and intelligent contracts published
by a firm and issue their audit opinion on the
blockchain. Finally, regulators and stock
exchanges will also become essential nodes in
the accounting blockchain to perform their
monitoring functions better.</p>
      <p>While firms must apply accounting methods
prescribed by accounting standards for
recording, presenting, and disclosing
information in traditional accounting, they still
have discretion over accounting methods, such
as accounting policies, estimates, and
judgments. Listed companies only provide
regular financial reports to the market but do
not disclose the accounting procedures used to
prepare the reports. While this institutional
arrangement can protect firms’ confidential
information, there are also several negative
consequences. First, the risk of falsification and
corruption of transactions exists regardless of
whether a company uses a paper or electronic
ledger. Secondly, managers or controlling
shareholders of listed companies may
manipulate or create transactions to maximize
their interests. Since the accounting process is
not transparent, it is tough for external
information users to detect problems. Finally,
even if external auditing exists, auditors may
not be able to detect all instances of fraud and
error in the firm or may lack the independence
to report problems to the market.</p>
      <p>As noted above, the technical
characteristics of the blockchain make the
disclosed information very transparent,
traceable, and protected from unauthorized
access. Voluntary disclosure via blockchain is a
beautiful way for companies that want to
reduce information asymmetry with investors.
In the short term, firms can disclose valuable
but non-mandatory information via the
blockchain, such as earnings forecasts and
corporate social responsibility reports. In this
way, self-disclosure helps investors better
understand the business and make more
informed decisions. In addition, even
disclosing publicly available information via
blockchain has many positive effects.</p>
      <p>On the one hand, historical information has a
specific reciprocal value. Especially in the case
of significant uncertainty, investors will verify
the available information by reviewing
historical information. On the other hand, the
disclosure of publicly available information
through official channels can influence
investors’ decision-making.</p>
      <p>In the long run, as firms and investors
recognize that voluntary blockchain disclosure
is a high-quality signaling mechanism to reduce
transaction costs, more and more companies
will choose to make voluntary blockchain
disclosures after balancing the benefits and
costs. However, as more information is
disclosed on the blockchain, comparability of
information will become an issue. Regulators
may require a standardization of information to
improve comparability.</p>
      <p>Anticipating that blockchain technology can
increase the authenticity, accuracy, and
comparability of disclosures and reduce
corporate earnings management; regulators
may even use blockchain as the primary
platform for mandatory disclosure. The
content of mandatory disclosure will be source
documents of transactions and events, as well
as accounting policies and methods embodied
in smart contracts. Such information should be
disclosed in real time based on current data.
Other non-confidential information, such as
earnings forecasts, corporate social
responsibility reports, and business reviews,
which are typical content companies would
like to disclose voluntarily in the short term,
should also be disclosed on the blockchain.
However, the frequency of disclosure should
be at the discretion of firms. If firms want to
make a good impression in the market, they
will be incentivized to disclose
nonconfidential information promptly.</p>

      <p>In summary, compared to traditional
financial reporting methods, blockchain
technology in financial accounting has
advantages such as high transparency,
traceability, timeliness, and protection against
forgery. In addition, smart contracts can
automate financial reporting, which can
significantly reduce financial accounting costs
and improve the timeliness, reliability, and
comparability of information. In addition, it can
also reduce errors in disclosures and earnings
management so that financial statements can
fairly and accurately reflect the firm’s financial
position and operating performance.
Accordingly, the problem of asymmetric
information can be mitigated. However, due to
the existing shortcomings of blockchain
technology, the above benefits will take time to
become a reality. With the development of
blockchain technology, blockchain accounting,
and financial reporting will become a viable and
attractive option in the long run.</p>
      <p>In the long run, using blockchain technology
in financial accounting has two main
implications. On the one hand, the raw data
published in the blockchain is tamper-proof. On
the other hand, smart contracts allow for
automated accounting and reporting, which
helps to track business activities. These changes
will make it more difficult for companies to
manipulate accounting data, but this does not
mean that using blockchain in financial reporting
can eliminate fraud. While the potential benefits
are large enough, firms still have incentives to
cheat by falsifying source data.</p>
      <p>As a result, one of the potential threats of
blockchain adoption in financial accounting is
that businesses may turn to creating
transactions to obtain desired accounting
metrics. In terms of auditing, this change
means that the control risk in audit risk will
decrease while internal risk may increase. In
such circumstances, the focus of auditors will
shift from preventing material misstatements
to analyzing the reasonableness and reliability
of the auditee’s activities.</p>
      <p>The accounting blockchain has other
threats if applied in the long term. These
include the shifting of accountants’
responsibilities, the problem of information
privacy for firms, and the growing complexity
of regulation. Blockchain technology could
automate the recognition, measurement,
presentation, and disclosure of information,
replacing the position of traditional financial
accountants in the long run. This reduces the
scope of traditional accounting tasks, such as
recording and preparing financial statements,
but creates more jobs to ensure the
authenticity of source documents and the
validity of smart contracts. This is a new
challenge for accountants.</p>
      <p>In addition, the issue of information privacy
in the short term only affects the amount of
information that firms voluntarily disclose on
the blockchain. However, in the long term,
radical changes in the automation of financial
reporting will significantly increase
companies’ out-of-pocket costs, which will
likely hinder the application.</p>
      <p>There is also the problem of increasing
regulatory complexity. Due to the diversity and
anonymity of nodes, speculators can take
advantage of the mining right to post “useful”
information to make a one-time profit. Even
false information can be detected quickly, and
it is difficult to identify the speculator who
posted the false information. In addition, the
presence of the “51% attack” also makes
regulation difficult. While it is difficult to have
more than 51% of the blockchain’s computing
power, there is a possibility of collusion.
Regulators cannot deter this action if it does
occur. One possible solution is to use a
permissioned blockchain instead of a public
blockchain. The basic idea of a permissioned
blockchain is that one central organization
controls who has the right to read and write
new information on the blockchain. This can
partially solve the problem of information
privacy and the growing complexity of
regulation. However, it would weaken the
fundamental characteristics of blockchain
technology, which are decentralized and
immutable.</p>
      <p>Financial accountants’ responsibilities will
shift from recording transactions and
preparing financial statements to ensuring the
authenticity of source documents and the
validity of smart contracts used in the
accounting blockchain. Other threats,
including the confidentiality of firms’
information and the increasing complexity of
regulation, could pose a barrier to the
application. One possible solution to address
these concerns is to use a consortium
blockchain instead of a public blockchain,
which would correspondingly weaken
blockchain technology’s fundamental
characteristics. In general, blockchain in
financial accounting has both opportunities
and threats. Moreover, when the technology
becomes sufficiently mature, it will likely bring
fundamental changes to financial accounting
and auditing, even to entire financial markets.</p>
      <p>
        The practice of implementing
blockchain technology in accounting and
auditing. The digitization of companies’
systems has allowed them to apply new
technological tools to simplify business
processes and transform business models to
innovate in their operations, as they can access
advanced computing power and large
databases. Academics, social media, industries,
and governments spend much time on digital
technology: blockchain, Artificial Intelligence
(AI), big data, the Internet of Things (IoT), and
cloud computing. These innovations are
significantly transforming businesses and
individuals, with blockchain providing the
foundation for a “value internet” that will
fundamentally change society and its
businesses. Since Nakamoto [5] laid the
groundwork for what became blockchain
technology in 2008, the banking, finance,
insurance, education, and government sectors
have used blockchain technology to the point
where 10% of global GDP will be recorded and
stored on blockchain by 2027 [
        <xref ref-type="bibr" rid="ref9">16</xref>
        ].
PricewaterhouseCoopers (PwC) estimates that
blockchain could increase global GDP by USD
1.76 trillion by 2030 [
        <xref ref-type="bibr" rid="ref3">10</xref>
        ].
      </p>
      <p>Deloitte’s 2020 Global Blockchain Survey
shows that companies are more committed
than ever to embedding blockchain in their
business. As blockchain matures, innovators
are discovering new opportunities to create
value and increase trust and resilience to
digital transformation by combining
blockchain with other forms of technology,
such as AI, IoT, or cloud computing. We look at
blockchain technology as a factor in increasing
transparency and trust in accounting and how
professionals can improve decision-making by
leveraging blockchain’s ability to provide
immutable and verifiable data. The main
characteristics of blockchain technology are
transparency, decentralization, immutability,
tamper resistance, strong authentication,
synchronized networks, and consensus. In
other words, blockchain technology allows the
transfer of anything of value, not only financial
transactions but also assets such as intellectual
property, health data, voices, and ideas.</p>
      <p>
        Blockchain technology affects the database
mechanism of an Accounting Information
System (AIS) by digitizing current paper-based
checks. The technology can securely store
accounting data such as accounts payable and
receivable and can improve the efficiency of
transaction accounting. Deloitte identifies
ways blockchain technology can solve current
accounting problems[
        <xref ref-type="bibr" rid="ref10">17</xref>
        ]. It can simplify
transactions, reduce settlement time and
counterparty risk, minimize fraud, and
improve regulation and capital liquidity [
        <xref ref-type="bibr" rid="ref10">17</xref>
        ].
      </p>
      <p>
        The primary purpose of using blockchain
technology for accounting is to create trust and
a trust network, with or without a trusted
party. Blockchain collects verified information
about the transaction amount, to whom and by
whom it was paid, then hashes and adds the
block to the existing chain. Combining hash
algorithms, private and public keys, and
decentralized ledgers makes blockchain
powerful in modern internet usage. Its
immutability, traceability, and visibility allow
participants to view fully encrypted,
synchronized transactions. The distributed
network [
        <xref ref-type="bibr" rid="ref11">18</xref>
        ], digital signatures, and
consensus verification rules make blockchain
safe and secure. According to the Financial
Accounting Standards Board, the trust derived
from blockchain comes from records being
tamper-resistant and unalterable due to their
distribution and hashing. Like fingerprints,
hashes are unique because every change, no
matter how minor, when information is added
causes the hash to change from one unique
identifier to another, as such changes mean
that its block is no longer the same.
      </p>
      <p>Blockchain is a cutting-edge technology that
can transform invoicing, payment processing,
contracts, and documentation. While cash,
receivables, payables, and inventory are
already updated in ERP systems, such records
are centralized and lack multi-party
verification. Blockchain allows encrypted
transactions that benefit from multi-party
verification to be publicly displayed, thus
enabling companies to provide real-time
balance sheets, income statements, cash
statements, inventory records, and capital
investment information relating to individual
counterparties, customers, auditors, and
regulators along the value chain. Because
blockchain allows for the instant exchange of
critical information, it can create a transparent,
real-time, verifiable accounting ecosystem
where managers, accountants, counterparties,
and investors can collaborate to verify
transactions and provide reliable evidence for
multi-party verification. Blockchain-enabled
real-time accounting will significantly reduce
opportunistic behavior by managers to engage
in accounting tricks and disruptive activities to
manipulate reported earnings. This is because
such accounting can allow participants to
instantly identify suspicious asset transfers
and other transactions that may pose a conflict
of interest.</p>
      <p>
        There are some studies and proposals on
using blockchain to publish and verify
information in real time. Using real-time
accounting data recorded in blockchains is
proposed to inform real-time audit and
reporting procedures [
        <xref ref-type="bibr" rid="ref12">19</xref>
        ]. J. Sogaard has
implemented real-time Value-Added Tax
(VAT) calculation using real-time accounting
information recorded through blockchain
technology [
        <xref ref-type="bibr" rid="ref13">20</xref>
        ]. Financial institutions can now
provide real-time services to ensure that every
calculation is reliable. For example, Ripple [
        <xref ref-type="bibr" rid="ref14">21</xref>
        ]
offers more accessible and faster cross-border
payments using blockchains on global
networks. Blockchain will not replace the XBRL
standard; it will be more effective if XBRL
provides high-quality structured data. XBRL
combined with blockchain can enable
realtime reporting and accounting [
        <xref ref-type="bibr" rid="ref15">22</xref>
        ].
      </p>
      <p>
        Some new initiatives that use blockchain
are related to triple-entry bookkeeping.
Tripleentry bookkeeping using blockchain
technology creates a shared ledger (journal of
records) that can be viewed across business
networks. A blockchain public ledger can
significantly increase transparency and trust
through multi-party verifiable records [
        <xref ref-type="bibr" rid="ref16">23</xref>
        ]. A
triple-entry accounting system is also
available, which adds a third level of records
called “credit” to explain additional income to
current debit and credit records. The
difference between triple-entry and
doubleentry accounting is that digitally signed
receipts are added and shared by each agent to
provide substantial evidence by sharing
records where the digitally signed receipt is
the third transaction, thus ensuring the
credibility and transparency of the records.
Triple-entry bookkeeping can also follow an
independent and secure template to increase
the reliability of financial reporting, thus
increasingly enabling the exchange of financial
information with blockchain participants. This
shared ledger can automate data reconciliation
to simplify the procedure and provide greater
confidence in decision-making. The reliable
presentation of financial statements can be
improved with shared data from independent
companies, a transparent system, and the
immutable, open-access storage provided by
blockchain. Of course, different businesses will
have different needs for triple-entry systems.
For example, banks have legal requirements to
track individual transactions, while other
businesses have more general requirements.
The design of triple-entry systems should be
aligned with the goal of a long-term business
strategy.
      </p>
      <p>Blockchain is changing the approaches and
tools for auditing. Traditional audit methods
must be revised to meet businesses’ current
and future needs in the digital economy.
Continuous auditing means using advanced
technologies to automate audit activities
continuously to test controls, analyze risks,
identify exceptions or anomalies, analyze
patterns, and view trends. It is likely to move
towards integrating artificial intelligence and
blockchain to form a coherent ecosystem to
improve assurance. Deloitte, Ernst &amp; Young,
PwC, and KPMG report that they plan to use AI
in audit planning, risk assessment, transaction
testing, analytics, and audit work papers to
reap the benefits of time savings, faster data
analysis, increased accuracy, more profound
knowledge, and better client service. “The Big
Four are committed to using artificial
intelligence systems, especially machine
learning, which allow a system to learn from
data to recognize/apply patterns and develop
a way to present new data. The introduction of
machine learning has paved the way for
advanced auditing, which can be enhanced
with blockchain.</p>
      <p>Ernst &amp; Young, for example, has launched a
“plug-in, always-on” approach to using
realtime blockchain data to replace current
practices. Blockchain can transform current
auditing into a more accurate and timely
automated assurance system and increase
trust in artificial intelligence systems. Once
records are approved, verified, and saved on
the blockchain, they remain unchanged. The
benefits of implementing blockchain in
auditing are as follows: continuous auditing
using blockchain reduces the task of manual
data extraction and audit preparation; in
companies engaged in service certification,
good blockchain connectivity makes it easier
for auditors to collect audit evidence and
provide information quality assurance
services; all records of business transactions in
the blockchain chain remain confidential and
secure.</p>
      <p>While artificial intelligence and blockchain
offer technological tools for auditors, they still
need data standards to provide meaningful
reporting. However, it is still being determined
whether current XBRL reporting standards
will be sufficient for artificial intelligence and
blockchain use. Whether XBRL can provide the
quality, unambiguous data needed to make
better use of AI and blockchain applications
remains to be seen.</p>
      <p>In addition to the areas mentioned above,
we also draw attention to the caveats that
companies should consider when
implementing this technology. Blockchain
does not provide one-size-fits-all solutions, as
they can be applied explicitly to different
situations and are not the only possible answer
or even the best one. However, blockchain can
solve current accounting problems by moving
to multi-party verification of transactions, thus
increasing trust and promoting digital
corporate reporting. While no technology is
foolproof, the blockchain can only be altered to
add false information or delete previous
information if someone gains 51% of the
computing power. However, their distribution
networks make this difficult to do with public
blockchains. The risk of hacking is even more
significant in private blockchains managed by
administrators, as a hacker can penetrate their
networks or they can change the rules and
content of private blockchains. Furthermore, it
is unreasonable to assume that businesses will
completely abandon their IT infrastructure
and replace it with a blockchain. Instead, it will
be one of the components of the IT
infrastructure, and companies will start
implementing blockchain in certain parts of
their business to coexist with existing legacy
systems, as not all data can be stored on the
blockchain chain.</p>
    </sec>
    <sec id="sec-4">
      <title>4. Discussions</title>
      <p>Accordingly, the proposed solutions are
analytical and conceptual, requiring additional
research and a detailed analysis of the
possibilities of physical implementation within
Ukraine and Ukrainian legislation.</p>
      <p>The following issues need to be investigated:
• Regulatory aspects and data privacy
issues in the implementation of
blockchain technology in accounting.
• Development of mechanisms to protect
against a 51% attack.
• Regulation of the regulatory framework.
• Studying the technical features of the
implementation of blockchain
technologies for enterprises,
institutions, and companies.
• Development of the concept of
blockchain technology implementation,
including its technical component.</p>

      <title>5. Conclusions</title>
      <p>The concept of blockchain technology, in
particular its decentralized and distributed
nature, has proven to be essential to ensuring
high reliability and immutability of financial
data. Blockchain technology allows data to be
stored securely, making altering or falsifying
data fraudulently complex.</p>
      <p>Research on the use of blockchain
technology in the economy shows its potential
to revolutionize financial accounting by
simplifying processes and increasing
automation. This becomes especially relevant
in today’s economic environment, where speed
and accuracy are crucial to the success of
businesses. The prospects for introducing
blockchain technology in accounting promise
to provide greater transparency, reliability,
and efficiency in processing financial [3]
information. However, it is essential to
consider regulatory and data privacy issues
when implementing this technology.</p>
      <p>Businesses, outsourcing, consulting, and
audit firms are actively considering
implementing blockchain technology to [4]
improve the quality of accounting and audit
processes. This will increase the reliability and
efficiency of financial reporting and reduce the
risks of information asymmetry and inefficient
management decisions. [5]</p>
      <p>Smart contracts are an essential
blockchainbased technology solution that changes
operational processes in accounting. Smart
contracts built on the blockchain allow you to
automate and regulate many accounting
operations based on predefined conditions. [7]
This increases the accuracy and speed of
information accounting.</p>
      <p>In general, introducing blockchain
technology improves the quality of financial
information, ensuring its reliability and
security. In turn, this helps to increase [8]
stakeholder confidence in financial statements.</p>
      <p>Thus, this study emphasizes the importance
and potential of using blockchain technology in
accounting, auditing, and taxation. It
demonstrates how blockchain technology can [9]
improve processes’ reliability, efficiency, and
transparency in various areas and emphasizes
its advantages in modern accounting and
auditing.</p>
