Abstract
Purpose Facilities management (FM) has become a revolutionary profession, which adds value to the
built environment. Compared to other industries, the development of the FM industry is at a preliminary
stage owing to poor adaptation of digitalisation. Although FM procurement process has improved over
time, it is still complex, inefcient and challenging with the lack of digital innovations. Blockchain
technology has emerged as a revolutionary digital technology under Procurement 4.0. The purpose of
this paper is to develop a framework that enables the effective use of blockchain technology for FM
procurement process.
Design/methodology/approach Data collection using interviews was performed in two stages
adopting a mono method qualitative methodological choice using case studies and survey strategies.
Template analysis and content analysis techniques were used to analyse the collected data.
Findings Through the ndings, main steps in the current FM process were identied. It was revealed,
manual procurement has issues related to, efciency, data security, communication and transparency.
Similarly, e-procurement systems also have issues related to data security, poor integration and transparency.
FM industry has identied the requirement of transforming into an advanced digitalised technology-based
procurement system. This study revealed, blockchain features to overcome these issues and the application of
blockchain technology in different steps of the procurement process through the developed framework.
Originality/value The developed framework offers a solution for the future technological transformation of
FM procurement using blockchain technology.

1. Introduction
A procurement process is necessary for the eld of facilities management (FM) to manage
the service providers, to obtain the required facilities of buildings and to continue a reliable
and efcient operation in the businesses (Pun et al., 2018). Hong and Kwon (2012) stated, as
procurement processes have become more challenging and complex because of rapid
changes existing in the competitive market, it requires the adaptation of an innovative
process to be more effective. Nicoletti (2017) stated, procurement requires a quick respond
with greater agility in the near future. Author further stated, as a result of Industry 4.0
initiative which is based on digital transformation, Procurement 4.0will inuence all
procurement processes which involve in the integration of information and communication
technology (ICT) and automation.
Ye et al. (2018) argued, when compared to industries such as the nancial industry,
manufacturing industry and aerospace industry, the development of the FM industry is

low. Authors further stated, this major issue is caused by the poor adaptation of
digitalisation for the management practices and it is essential to adapt new
technologies for the improvement of the FM industry. When digital transformations
occur in major business organisations, Facilities Managers need to embrace the change
and adapt these technologies to full the core business requirements (Jones Lang
Lasalle, 2016). According to Koch et al. (2017), there has been a series of technologies
that seems to enable FM digitalisation, such as, Building Information Modeling,
blockchain, Internet of Things (IoT), big data technology, augmented reality and
building information standards.
Conley and Richards (2018) stated, facilities managers are interested in blockchain
technology (BCT) because it can be applied for effective data sharing and data protection
while improving interoperability and reducing costs. According to Loebbecke et al. (2018),
BCT has inuenced the success of the economy because of the condence and trust available
through transactions. Authors further stated, documentation practices can be further
improved by BCT through secured and transparent transactions. Nicoletti (2017) stated,
security and safety of the procurement process can be improved by applying BCT to the
entire procurement process.
Blockchain is a decentralised ledger where a third party is not required to manage the
data and all the blocks are linked together to check all the transactions (Tavares, 2018).
According to Shu (2017), when data are recorded in the distributed blockchain ledger, this
data are veried and they cannot be changed or deleted. BCT can offer efcient and secure
record-keeping, which is useful for the maintenance and management of records for a long
time period (Lemieux, 2016).
Facilities managers have not considered the requirement of BCT for a secured and
effective procurement process. Therefore, it is required to transform the current
procurement process into an advanced digital technology where transactions and payments
could be managed automatically in an efcient and secured manner. Therefore, it is required
to analyse this gap in adapting BCT by the facilities managers for the future development of
the procurement process.
Thus, this research aims to develop a framework that enables the effective use of BCT for
FM procurement process. Recently, researches have conducted on applications of BCT, and
this is the rst research to analyse this gap in adapting BCT by the facilities managers for
the future development of the procurement process. The research scope was limited to
identifying the procedures that enable the effective use of BCT for the FM procurement
process.
2. Literature review
2.1 Procurement process
The timely requirements of the organisations are identied at the beginning of the
procurement process and payments to suppliers regarding goods and services are settled at
the end (Uddin, 2015). However, Heggstad and Frøystad (2011) argued, there is a common
mistake of focussing only on the tendering, signing and awarding the contracts of the
procurement process. Authors further stated, procurement process consists of some other
important steps as illustrated in Figure 1.
Hawking et al. (2004) argued, owing to slow and unsystematic business transactions, the
manual procurement process has become an expensive business activity over the past few
years. The manual procurement process is a long and slow paper work-based process which
reduces productivity while wasting money (Shukla et al., 2016). Subsequently, authorised
persons require to identify and clarify errors related to manual procurement process which
JFM
consumes more cost and time. Because of the lack of transparency in procurement activities
of many countries, traditional procurement systems have led to unwholesome activities such
as corruption, inated costs, progress delays of project developments and purchase of goods
and services (Hui et al., 2011). According to McConnell (2009), main process related issues of
manual procurement are procurement complexities in goods and services, availability of
many suppliers, inability to adapt to complicated procedures and lack of transparency.
The procurement process has evolved with time because of the increase of the complex
integrations among procurement functions in organisations and with the increase of
procurement relationships with suppliers (Tunisini and Sebastiani, 2015). Okinyi and Muturi
(2016) revealed, an ICT-based procurement process performs more effectively when it functions
manually. Many attempts have been carried out for procurement reengineering with the use of
different information technologies, and however, EP (E-procurement) is the most successful
goal achieved in procurement reengineering (Kothari et al., 2005). However, Premathilaka and
Fernando (2018) argued, EP adoption has a negative relationship with supplier readiness
because suppliers are reluctant to trust electronic systems in organisations.
According to Chepkmoi (2014), security is the major obstacle for EP because of
unauthorised access and hacking of systems which can damage the companys information.
Author further mentioned, verication and implementation of procurement contracts and
protection of private information are the main legal issues. Hui et al. (2011) argued, even
though it was expected that the negative impacts of procurement will be solved by the
introduction of EP, still the main issues such as transparency, corruption, integrity,
accountability and cronyism are present.
2.2 Digitalisation of procurement using advanced technologies
Blockchain, articial intelligence (AI)/robotic process automation (RPA), 3 D-printing and
IoT are the most prominent digital technologies which inuence on the procurement process
in organisations (Karmehag and Löfnertz, 2018). Authors further stated, above technologies
can impact on future procurement process development in four different ways where BCT
could change the procurement process completely and improve more business transactions.
Nicoletti (2017) emphasised, Procurement 4.0is a revolution in EP and among the future
implementations, blockchain acts as a digital consensus mechanism that enables smart
contracts which act as automated contracts for thefuture of procurement.

Blockchain
technology
Many of todays experts, who were present at the invention of the internet believe that BCT
will become outstanding than the World Wide Web (WWW) (Kinnaird and Geipel, 2017).
Lemieux (2016) stated, BCT is a database of distributed transactions in which various
computers, referred to as nodes, work together as a system to store bits in a sequential order
which are encrypted as blocks and then linked to form the blockchain. BCT has emerged
from distributed ledger technology (DLT) which provides a consensus verication
mechanism over a computer network while enabling peer-to-peer transactions without
requiring an intermediate or centralised person to update and manage transaction-generated
information (Rennock et al.,2018). Hileman and Rauchs (2017) argued, unlike other
distributed databases, network participants of the blockchain have the ability to verify the
integrity of a shared database independently without the involvement of trusted third
parties.
2.3 Application of blockchain technology for procurement process
Zheng et al. (2017) argued, although most blockchains are currently used in the nancial
sector, some other applications are emerging in different areas. Authors further mentioned,
traditional industries can consider BCT and apply blockchains to their areas to enhance
operations of their systems.
According to Hileman and Rauchs (2017), the current DLT focus still exists mainly in the
use of money, which may result because rst blockchains were mainly focussed on
currency-related applications. However, Nicoletti (2017) argued, a shared database can help
a variety of stakeholders who are involved in the procurement process such as the company,
its customers, suppliers, partners and regulatory agencies where necessary and it enables
reliable and uninterrupted procurement process. According to Härer (2018), through the
implementation of a decentralised plan for the purchase order process, suppliers without
long-term relationships can immediately join the process based on the information in the
process model protected by the blockchain. The applicability of BCT for different steps in
the procurement process as identied by researchers is presented in Table 1.
Studies have not further examined the application of BCT for the FM industry with an
appropriate procurement operating model. Therefore, it is required to investigate the BCT
application. Accordingly, the conceptual frameworkillustrated in Figure 2 was developed as
a guide for the effective use of BCT for FM procurement operating model.
Figure 2 illustrates the conceptual framework which is developed based on the ndings
summarised in Table 1. Here, the main elements of the procurement process stated by OECD
(2009) are considered as the phases of the procurement process and the subtopics under each
phase. It is proposed to use this conceptual framework throughout this study to determine
the current level of applicability of BCT for FM procurement process.
3. Research methodology
The research process was developed based on the research onion introduced by Saunders
et al. (2016). This research is focussed on developing a framework by understanding current
FM procurement process and identifying applicability of BCT for this process. The
researcher requires to identify the research environment to identify and interpret different
views of the people. Therefore, the research inclines more towards an interpretivism stance.
Saunders et al. (2016) explained, deductive reasoning is where the theory is developed
based on literature and a research strategy is designed to test the theory, while in inductive
reasoning a theory is developed by collecting data to explore a phenomenon. Authors
further explained, in abductive reasoning a new theory is developed or an existing theory is
modied which is tested with additional data collected. The abductive approach was

followed in this study. First, a conceptual framework was developed based on existing
literature related to the application of BCT for the procurement process. Then the conceptual
framework was rened using the evidence related to existing data and new data based on
the analysis of the data collected through the expert survey.
Experiment, survey, action research, case study, research, ethnography, grounded theory
and narrative research are the main qualitative research strategies (Saunders et al.,2016).
Two types of strategies were considered in this research. First, multiple case studies were
conducted regarding the selected organisations. Current procurement process followed by
facilities managers in selected organisations were identied by conducting semi-structured
interviews. Then, the applicability of BCT to each step of the above identied procurement
process was identied using an expert survey.
According to Saunders et al. (2016), a cross-sectional study is considered as the study of a
particular phenomenon at a particular time, whereas longitudinal study is considered as the
study of the change and development in measuring some variables. This research falls
under the cross-sectional study because this was conducted within the time constraints.
3.1 Case study
A case study is the most popular strategy for qualitative analysis which involves the careful
and in-depth investigation of a specic case related to a social unit (Kothari, 2004). As this
study is focussed on enabling the effective use of BCT for FM procurement, selection of

multiple cases to study the current procurement process, existing issues and BCT
applicability are more appropriate. Therefore, to obtain a reliable conclusion, multiple cases
were selected and details of each case study are summarised in Table 2.
3.2 Expert survey
According to Kelley et al. (2003), survey strategy includes questionnaires and interviews.
Authors further stated, experts in the eld, colleagues or members of the target population
can be selected to ensure the validity of the survey. Two types of experts are identied as
normative and substantive where normative expertise comes from experience in the eld
and substantive expertise comes from the knowledge in making judgements (Meyer and
Booker, 2001). In this study, normative experts who are currently engaged in the IT eld and
has contributed to developing blockchain-based solutions and projects were considered as
experts. Details of each expert are summarised in Table 3.
4. Data analysis and ndings
Template analysis is where a coding template is developed using the data and then rearranged to
obtain a satised template (Saunders et al.,2016). In this study, template analysis was used to
analyse the collected data from case studies and the expert survey. Through the template analysis
of case studies, current FM procurement process was developed as illustrated in Figure 3.

Cases which use manual procurement have facedissues such as security issues, transparency
issues and time delays similarly as specied in the literature (McConnell, 2009;Hui et al.,
2011;Shukla et al., 2016). Additionally, communication errors were identied as another
issue of the manual system. Further, when considering cases which use EP system, still
issues are existing as specied in the literature by Chepkmoi (2014). Therefore, currently, in
the Sri Lankan context ensuring adequate transparency and security have become serious
issues in EP. Further, it was identied there is an issue of lacking a proper recording
mechanism. Therefore, it is evident that the EP system should be developed based on a more
advanced digital technology to mitigate these issues. However, in both cases, poor
integration of authorised parties,time delays in obtaining service requirements and approvals,
frauds in transactions through third-party intervention were identied as signicant issues.
Therefore, in this study blockchain features to overcome each issue were identied from
expert views. However, before applying BCT it was necessary to identify the respondents
awareness on BCT. R
A

B
stated, aware of the term Blockchain,but not aware of its
applications.R
C
stated, as a global organisation have used blockchain for trade transactions,
but not in FM. Therefore, it was evident that application of BCT for FM industry is a
revolutionary concept. Thus the application of blockchain features for each issue were
identied as follows.
4.1.1 Issues in pre-tendering phase and blockchain features to overcome them. R
A
and R
c
stated, poor integration of authorised parties is the main issue in client organisations
because integrating authorised parties in various departments is more time consuming
when carrying out discussions with each department, as they are not integrated through a
system. E1 stated, an interface can be provided on top of the blockchain platform, data
related to issues/requirements in the building can be fed as requests and it can be
maintained as a request management ledger. E1 further stated, users can be enabled to log in
to the system and communicate service requirements in the building by giving a User ID

stated, communication errors are existing in addressing service requirements. E1
further stated, above mentioned request management ledger can be used for the notication
of service requirements and persons who need to view such as facilities managers can get
notications when logging into the system to solve this. However, E5 stated that use of
smart contracts to communicate the requirement of a tendering process can overcome this
issue and can be informed to the procurement department through a smart contract.
R
A
and R
C
stated, obtaining service requirements and approvals are time-consuming. E7
stated, IoT Integration to automatically update service requirements can instantly update the
blockchain regarding the service requirements. E1 expressed an opinion of using AI
integration to provide maintenance based solutions through the obtained records which can
analyse and predict solutions. As per the opinion of E3 and E5, it can automate approval
process using smart contracts to solve this issue and if anything is approved it is added to
the blockchain as a new block, then using smart contracts this approval process can be
automated.
4.1.2 Issues in tendering phase and blockchain features to overcome them. According to
R
A
,executing the tendering process is time-consuming. E2, E3, E6 and E7 stated that
blockchain can be used to publish tenders and notify service providers and send tender
requests as a transaction through the blockchain because tenders cannot be modied. So
these tenders can be saved in blockchain and it can be managed through blockchain. Further
E7 stated, when a new tender is published via the blockchain, it will update registered service
providers automatically owing to the distributed nature of blockchain architecture.
In the tendering phase, transparency issues and lack of data security are other main issues
as mentioned by all the respondents. E7 stated, keys can be used for encryption mechanism
where, sensitive information should be encrypted and only the key holders can decrypt the
information. E1 further explained, the public key is broadcasted to everyone in the network
and it can be veried only by this public key. When the message is public, data can be
encrypted using public key but data can be decrypted only by the person with the private
key. E3 described the process of using hashing mechanism as, hashes can be generated and
kept in the blockchain and then it can be veried. E2 described a different process of using
hyperledgers to enhance condentiality by creating a private transaction with the
organisation and the service provider.
4.1.3 Issues in post awarding phase and blockchain features to overcome them. R
A
stated, preparing and managing contracts and purchase ordering are time-consuming, while
R
C
stated, purchase ordering is not automated and it is time-consuming. All the experts
agreed that smart contracts can be used for FM procurement contracts. E1 stated, it is better
to have a contract with service providers and organisations in terms of payments and
conditions of contracts. Therefore, contracts can be managed effectively by the use of smart
contracts programmed on top of the blockchain for repetitive tasks where human intelligence
is not required.
As per the opinion of E7, blockchain can be used to automate the purchase ordering
function according to the stock level by integrating stock levels with blockchain. According to
the stock level, blockchain will automatically manage the purchase ordering function.
R
A
and R
B
stated there are data sharing issues with authorised parties. E1 stated, this can
be solved using smart contracts and write what is private and public according to the
implementation of smart contracts. E2 added, there are different people with different roles,
and it is required to validate which particular roles have the capability to get that
information.
JFM
R
A
stated, there are issues in inefcient data retrieval and loss of data while R
C
stated,
there is an issue in the absence of an automatic recording mechanism. Most of the experts
stated that blockchain can be used to track and rene transactions because it is a distributed
ledger which records transactions. E3 stated, history viewing is enabled from the details
recorded in the blockchain because it has past information written in a tamper-proof way. So
basically authorised parties can refer those transactions.
All the respondents stated, occurring of frauds in transactions through third party
intervention is the main issue in the post awarding phase. All the experts stated, eliminating
intermediary and enabling direct transactions with authority integration and proper
verication can solve this issue. Thus, blockchain facilitates the storing of transacted
information in multiple locations where the trusted intermediary such as banks are removed
from the picture and direct transactions are executed through the digital trust.
5. Discussion
Data analysis and ndings have revealed BCT can be applied for FM procurement beyond
the identied blockchain applied steps of procurement process specied in the literature.
Ying et al. (2018) stated public keys and private keys can be used to verify the service
provider participation to a tender or for the qualication. According to the data analysis, it
was identied it is possible. Additionally, it was identied service providers can be veried
from the hashof past data in each data block of the blockchain. Therefore, if these service
providers have performed their services earlier both their identity and services can be
evaluated from this past data. However, from the data ndings, it can be argued that it
cannot be performed using blockchain and a different party is required for the validation of
service providers because they can fraud themselves when registering into the system and
after registering we may consider them as veried service providers.
Though Banerjee (2018) stated, blockchain provides a unied business messaging system, it
was found that information exchange is enabled only among the clients who are integrated
through blockchain. Further, it was revealed that using blockchain as a communication medium
is not the purpose of blockchain and using email as a mode of information exchange is sufcient.
As specied in the literature (Fairley, 2015;Nicoletti, 2017;Rejeb et al.,2018), blockchain is
considered as a digital register to record information. Through data analysis, it was revealed
that blockchain should be used only to store the transaction-related information and any other
information related to budgeting and service providers should be recorded in a separate
database. The unnecessary use of BCT will abuse the technology and it will be not effective.
It was revealed from literature (Banerjee, 2018;Gans, 2019;Nicoletti, 2017;Rejeb et al.,2018)
contracts can be automated using smart contracts and payments can be executed through smart
contracts. Data analysis revealed, smart contracts can be used for FM procurement contracts
between service provider and organisation in terms of payments and conditions of contracts
with a dened logic. However, here the law is an issue and it would be necessary to consider this
as a legally binding contract. Therefore, rules and regulations should be dened. As specied in
the literature (Manseld-Devine, 2017;Martínez Martínez, 2019;Ying et al., 2018), nancial
transactions can be performed through cryptocurrencies. Data analysis revealed, in addition to
cryptocurrencies a token-based system can be used. As emphasised by Nakamoto (2008),
ndings proved that nancial institutions can be eliminated to perform direct transactions.
It was identied that IoT can be integrated with BCT to facilitate the proper
communication of service requirements. Whitmore et al. (2015) stated IoT is where things
are able to identify, detect, process, establish networks and allow them to communicate via
the internet. Thus, requirements identied through IoT technology can be directly sent to
BCT-based system. Further, it was revealed that AI technology can be used for this purpose.
Blockchain
technology
AI is the use of intelligent behaviour to perform any task by a program or a machine with
the use of computer modelling(Hamet and Tremblay, 2017;Heath, 2018). Thus requirements
can be identied through programming.
5.1 Framework for the eective use of blockchain technology for facilities management
procurement
In addition to the BCT features to overcome the issues in current FM procurement process, all
the positive responses expressed by experts in applying BCT for procurement process were
selected to for the purpose of developing the framework to ensure the applicability. Further,
details in the conceptual framework were used similarly in the framework. Denition of
requirements and choice of procedures under pre tendering phase were not considered for
developing the framework because they are not signicant for the application of BCT.
Expected users of this framework are the clients and FM service providers who face
issues because of the prevailing manual procurement and EP systems. This can be guided to
understand the applicability of BCT for an advanced digitalised procurement system.
Further, blockchain developers can use this framework to develop a BCT based future
solution for FM procurement process (Figure 4).
6. Conclusions and recommendations
Through this study, the main steps of the FM procurement process were identied and
presented in a concise manner under three phases of procurement; pre tendering, tendering
and post awarding phase. FM industry has identied the requirement of implementing an
advanced digitalised procurement system for both manual procurement and EP systems.
As a future implementation of Procurement 4.0, BCT can be considered as an important
digital innovation for FM industry. When considering the identied steps in FM
procurement process, BCT can be applied to solve the current issues in both manual

procurement and EP systems in terms of data transparency, data security, time delays, poor
integration of authorised parties and third party intervention. It was revealed, by developing
aRequest management ledgeron blockchain platform for the communication of issues/
requirements in the building is the rst step of this signicant transformation. IoT
integration to automatically update regarding service requirements and AI integration to
analyse and predict maintenance-based solutions were identied as further improvements
in this development. Other blockchain features such as, data encryption mechanism,
hashing mechanism and hyperledgers can be used to overcome the main issues of data
transparency and security. Further, enabling direct transactions by eliminating
intermediary is a key blockchain feature to solve the main issue of frauds in transactions
through third-party intervention. It was revealed that smart contracts which is programmed
on top of blockchain for repetitive tasks can be executed between service providers and
organisations in terms of payments and conditions of contracts. However, new rules and
regulations should be dened to consider them as legal contracts.
The main contributions of this research are identication of the FM procurement process and
development of the knowledge on the applicability of BCT for FM procurement process by
identifying the existing issues in manual procurement and EP. IT industry will be benetted by
the outcomes of this research and it can be recommended to use them by considering only the
most appropriate activities related to the procurement process without overusing BCT to
develop a BCT based procurement system. Further, research ndings will be benecial for
clients and service providers in the FM industry to transform into a BCT based procurement
process to enhance the efciency. Although the research aim was achieved at the end, some
unavoidable limitations were encountered while carrying out the research study. The main
limitation was the lack of professionals in the IT eld with experience and explicit knowledge in
BCT because BCT is still at its preliminary stage in the Sri Lankan context. However, adequate
information was obtained from the seven experts selected and the data saturation was achieved.

... Um framework de estruturação do conhecimento permite intermediar a organização do conhecimento emergente de dados oriundos de especialistas (Albuquerque, 2016). Proposições de framework de implantação podem ser identificadas em estudos recentes sobre blockchain (Thio-ac et al., 2019;Gunasekara et al., 2021). No framework proposto, a etapa do processo de compra prevê a habilitação de chaves compartilhadas, tornando possível que a organização pública possa identificar as movimentações dos candidatos a fornecedores. ...
... Tal formato está em conformidade com os princípios da blockchain identificados em estudos (Iansiti & Lakhani, 2017). Estudos apontam ser necessária uma complementação para evitar fraudes no processo de registro (Gunasekara et al., 2021). Logo, sugere-se que o endereço alfanumérico de cada fornecedor pode ser validado através dos certificados di-gitais atualmente utilizados pelas empresas para certificação de diversos acessos a sítios públicos. ...
... Para a etapa da liquidação, a proposição envolve dos fatores relevantes: a automatização do processo de aprovação orçamentária e a utilização de rastreamento logístico para acompanhar o recebimento dos produtos. A estrutura propõe o uso das assinaturas digitais para pré-validar a disposição orçamentária, e o uso de smart contracts para operacionalizar a liquidação, em formato similar ao já proposto em outros estudos (Thio-ac et al, 2019;Gunasekara et al, 2021). O rastreamento logístico, já mencionado no parágrafo anterior, tem possibilidades de uso interessantes quando associado a blockchain (Kummer et al., 2020), podendo contribuir tanto para a confirmação de entrega do fornecedor quanto para a validação do controle de estoque da unidade gestora. ...

(2022) developed a blockchain-enabled occupational safety and health deployment framework to create privacy and occupational safety, while Liu et al. (2022) and Gunasekara et al. (2022) explored the possibility of using blockchain in waste management and facilities management, respectively. While the earlier two articles demonstrate prototypes, these studies are limited to conceptual framework and interviews. ...
... When pondering on key areas of focus, it should be noted that applications of blockchain in procurement related areas are the most present among the articles retrieved for the study (Ibrahim et al., 2022;Nanayakkara et al., 2021;Tezel et al., 2021), taking a larger area of figure 6, suggesting that the potential of blockchain is the most in procurement phase of a construction project when compared to others, while closely followed by design & construction (Ni et al., 2021;Sigalov et al., 2021;Yang et al., 2022). However, when considering the operations & maintenance, though this category has not gained the depth in research like the earlier two based on the number of articles, studies have touched several areas of application such as waste management (Gunasekara et al., 2022), property transactions , and asset tracking (van Groesen & Pauwels, 2022). Similarly, sustainability related research are also yet to gain popularity, judging from the number of articles. ...

Blockchain is often considered a potential disrupter in how industries operate, due to its decentralised nature and several other salient features like enhanced security, transparency, traceability, immutability etc. The Construction Industry, though regarded as a late adopter of technologies, is striving to harness blockchain to improve its processes. The subsequent research initiatives, however, are scattered around several application areas, with different levels of maturity. This would prove troublesome for a potential researcher to identify a suitable research gap and carry out impactful research. Addressing this, the study attempts to identify the evolution of blockchain research in the construction industry and its current and future trends through a systematic literature review. The review identified that blockchain research is gaining popularity in construction sector exponentially and is expected to continue that pace. The developed countries are dominating these application oriented researches while developing economies are lacking behind. Research on adopting blockchain in procurement and design and construction processes has been done substantially while newer topics are evolving since the beginning of this decade, focusing on the sustainability initiatives of the sector and fusing other digital technologies with blockchain. It is believed that while procurement and design related researches iterate their findings, these new topics would define the blockchain researches in the years to come. Also, attention should be paid on holistically evaluating the blockchain solutions considering not only the technological aspect but also the sustainability, resilience and the productivity of the industry, which is yet to be observed in the studies.

The modern world has its foundation built on data. Data is generated all the time, and many aspects of the society and economy are built upon it. In today's world, data is employed in better decision‐making, innovation, and improving the efficiency of systems. It becomes essential to protect it from being tampered with or misused. Encryptions based on cryptographic systems are used in mainstream data protection these days. There have been newer iterations of mechanisms based on new techniques using blockchain and the zero trust model and even systems that employ fog computing along with content delivery networks. The advent of computation through quantum technologies also helped in developing data security with post‐quantum mechanisms. The critical conditions for the working of these mechanisms hinder their adoption primarily. This also leads current systems to lack one or more of these technologies. Thus, the importance of a unified system that can employ quantum technologies effectively becomes prominent and requires a definitive investigation. In this article, a Quantum‐IoT‐based data protection scheme that can be of value to Industry 4.0 is analyzed. Light is also shed on innovations in quantum computing that can help solve not just current problems but also the future.

The built environment (BE) profession, encompassing disciplines such as architecture, urban planning, civil engineering, and construction management, plays a pivotal role in shaping the physical spaces we inhabit and enhancing the socio-economic status of the people. As the BE continues to grow in complexity and faces the challenges of increased urbanisation and the need to embrace sustainability concepts, it becomes imperative to equip future professionals with the necessary knowledge and skills to navigate this dynamic sector. In this context, the integration of digital technologies (DTs) into the teaching and learning (T&L) process has emerged as a transformative approach with immense potential. Therefore, this study aims to explore the prospects and significance of DTs for T&L within the BE profession. This study aims to shed light on the transformative role that DTs can play in the education of future professionals. An extant review of the literature was conducted on DTs with the capacity to enhance the pedagogical processes and experiences of BE students. The findings revealed that DTs offer numerous advantages, such as the promotion of collaborative learning and communication, enhancement of visualisation and simulation capabilities, promotion of immersive experiences facilitated by virtual and augmented reality, and access to a wide range of resources. In conclusion, the integration of DTs into the T&L of the built environment profession holds immense promise. By enhancing visualisation, promoting collaboration, providing access to resources, facilitating personalised learning experiences, and bridging the gap between theory and practice, DTs have the potential to equip BE students with the necessary skills to thrive in this rapidly evolving world.

This paper reviews the potential applications of Digital Twins (DT) and Blockchain (BC) technologies throughout the building lifecycle phases by conducting a double-stranded systematic review of papers on the possible use of DT and BC. The results revealed the increasing interest in DT and BC and their potential use in all building lifecycle phases; however, studies focused mainly on the construction phase. The findings also revealed unique features of DT and BC, potentially supporting the proposal for their collaborative implementation to enhance building lifecycle management. This review's findings positioned the argument for more research on integrating DT and BC to augment building lifecycle management and the need to explore their relevance or role when transitioning from construction to post-construction. This paper elucidates readers on the potential role of DT and BC while developing a built asset and suggests directions for future research.

This work aims to illuminate an often-unaddressed topic of how to best design Oracles in application to the AEC industry. To answer this, the paper reviews the state-of-the-art of existing Oracle taxonomies, literature on blockchain for AEC that implement Oracles, and proposes Oracle design dimensions to frame future blockchain work. The work can help researchers and practitioners to think about relevant dimensions when designing and discussing Oracles for AEC use cases.
... In most cases, anybody may join the Bitcoin network and transact with other users since the blockchain is open to the public. To keep track of its expanding list of blocks, each of which is a single transaction record, blockchain uses encryption (Gunasekara et al., 2022;Meng et al., 2018;Xu et al., 2021). Blockchain transactions become permanent after they have been updated and authenticated by all necessary parties. ...

Abstract The transition to a circular supply chain (CSC) is a prerequisite to establish sustainability in the supply chain. Blockchain-based CSC enables stakeholders to effectively manage their decision-making processes, increase revenue, reduce time and costs and ensure information synchronisation. Blockchain start-ups play an essential role in facilitating the transition from a linear to a circular economy while supporting the development of CSCs. This research aims to explore the role of blockchain entrepreneurship in the transition to CSC by evaluating circular blockchain start-ups. This research contributes to the literature by providing verified roles of blockchain entrepreneurship in the transition to CSC by evaluating the literature and blockchain start-ups. Another contribution is that the causal relationships between these roles are analysed. In this study, an integrated three-step methodology including Systematic Literature Review (SLR), Qualitative Comparative Analysis (QCA), and Fuzzy Decision-Making Trial and Evaluation Laboratory (Fuzzy-DEMATEL) methods on the base of the theory of change is proposed. An SLR is performed to determine the roles of blockchain entrepreneurship. Then, a QCA is conducted after identifying the roles for verification by evaluations of use cases of blockchain start-ups. Finally, the causal relationships between these roles are interpreted by using Fuzzy-DEMATEL. Findings indicate that blockchain entrepreneurship has 12 fundamental roles in facilitating the transition from a linear to a circular economy while supporting the development of CSCs.

The Architecture Engineering and Construction/ Facility Management (AEC/FM) industry plays a significant role in the development of economy. In recent years, the wide application and development of Building Information Modelling (BIM) promote the development of informatization and digitalization of AEC/FM industry. However, due to the limitation of a one single tool and lack of understanding of single source of truth, the problems of the industry cannot be solved completely. Therefore, the revolution and innovation of industry can be stagnated. Internet of Thing (IoT) and blockchain can be considered as two technologies that can be integrated with BIM for AEC/FM industry. The aim of this paper is to understand and analyse the basic principles and the applications of these three technologies in AEC/FM industry through literature review. With the integration of these three technologies, the virtual and realistic object and data during the whole building lifecycle can be managed and stored in a security, transparency and convenient decentralized common data environment (DCDE). Finally, a theory named, Cup-of-Water theory is presented.

Blockchain, the distributed ledger underlying bitcoin, has attracted much attention and stimulated rich discussions. However, extant discussions are mostly conceptual expositions, and empirical evidence of how to use the technology is limited. This case analysis fills this gap by conducting a study on Hainan Airlines (HNA) group, a large conglomerate, which has successfully implemented a blockchain-enabled E-commerce platform to offer employees flexible benefits. The case study unveils that blockchain of value in three ways: 1) issuing crypto-currency, 2) protecting sensitive information, and 3) eliminating institutional intermediaries. These findings provide a reference point for IT and general managers who intend to use blockchain to digitally enable their organizations further.

Online auction is one of the most successful internet business models. However, auction fraud has become the highest threat and hazard to the future of this business model. The blockchain provides a new perspective to resolve this problem. It can be used for current financial services, certificates, remittances, and online payments; meanwhile it also provides several crucial services such as smart contract, smart property, trust system, and security services. This chapter discusses how to apply blockchain to a cloud-based online auction and the principle of operation. The purpose is to fundamentally solve the problem of online fraud caused by information asymmetry of electronic transactions. To the best of the authors' knowledge, this is the first time that the blockchain has been applied to authentication of online auction. The preliminary contribution is for preventing auction fraud from the aspects of smart properties and smart contract.

The future of procurement is extremely interesting. Industry 4.0 is at the basis of the fourth industrial revolution. It is indeed a revolution also for procurement. This chapter presents an innovative and comprehensive model for Procurement 4.0. In comparison with traditional approaches, for instance for e-procurement, Procurement 4.0 represents a real revolution. For this reason, the analysis and use of the model is essential to substantiate Industry 4.0. This initiative until now has been very much a vision and an experiment rather that a solution to be approached in a scientific way. The innovative model presented could be of use to academicians studying Industry 4.0 and to procurement practitioners in organizations. A new solution is particularly important to support Procurement 4.0. It is named blockchain and it is already successful in supporting Bitcoins. The chapter presents the characteristics of this solution and its possible applications. Two uses of blockchain are particularly important: procurement finance and smart contracts. The chapter presents their characteristics and their potential uses.

Mention the word ‘blockchain’ to most people and, assuming that they've heard of it at all, they will most likely associate it with Bitcoin, or perhaps another crypto-currency. As a decentralised, cryptographically authenticated record of transactions, the blockchain is the key concept that makes Bitcoin feasible. Yet, as Patrick Hubbard, technical product marketing director at SolarWinds, explains in this interview, the same concept has applications far beyond the contentious world of alternative currencies – in fact, far beyond finance altogether.
