Scope: Development of a Reputation
Mechanism for Research Infrastructures,
integrated with EERIS
Project “Increasing the capacity of the
RDI system to respond to global
challenges. Strengthening the
anticipatory capacity for evidence-based
public policy making - SIPOCA 592”,
UEFISCDI.
EERIS.eu: Engage in the European Research
Infrastructures System
- developed and hosted by the Executive Agency for
Higher Education, Research, Development and
Innovation Funding (UEFISCDI)
- a booking gate where specialists and companies can
engage with public and private European research
infrastructures in order to carry out research, by
interacting with services, equipment and experts.
1. EERIS Network description. Scope of the
project
Reputation is the recognition by other
people/entities of some characteristic
or ability (Merriam-Webster
dictionary);
Few attributes are more important to
identity and trust than reputation
(Arun and Carmichael, 2017);
Reputation could be seen as a global
perception of an entity's behavior
based on the trust established by the
other entities in a system.
In order to guarantee an objective measurement of
reputation, a reputation management system has to be
designed:
- a possible approach is to establish a central authority to act
as the agent of trust, but such a solution does not eradicate
the root cause of mistrust
- another approach: a distributed reputation system based on
Blockchain; to measure an individual’s or an institution’s
propensity to do what they promise, data tracked for past
performance on a Blockchain could be used, while access to
the data on a Blockchain becomes a new verifiable basis for
reputation, which can visibly demonstrate trustworthiness to
their potential clients and partners.
2.1. Reputation
The Blockchain is a type of Distributed Ledger Technology (DLT), an append-only chain-like data
structure, made out of signed and timestamped blocks that contain the transactions (Holotescu
and Vasiu, 2020).
2.2. Open Research
Our approach follows the principles of Open Research/Science recently defined by UNESCO
Recommendations on Open Science, European Union's Open Science policy, and Open Science
Knowledge Hub Romania.
UNESCO Recommendations on Open Science, published in November 2021:
“Open science increases scientific collaborations and sharing of information for the benefits of
science and society; also opens the processes of scientific knowledge creation, evaluation and
communication to societal actors beyond the traditional scientific community.”
Blockchain and Open Data share similar principles such as the promotion of transparency,
equality in information knowledge and access, as well as the reorganisation of data exchange
between a number of parties (data.europa.eu, 2018).
The decentralization brought by Blockchain enables researchers to build their own open
ecosystem for research data, metadata, and communication that follows the philosophy of
open research, thus everyone can openly participate, collaborate, and contribute to science.
The results of these activities, such as research data, processes, studies, and methods, are
freely available so that they can be reused and reproduced (Leible et al., 2019).
The implemented reputation mechanism aims to increase openness, impact, and technology
transfer of research infrastructures (RIs) and is designed not only to measure reputation, but also
to make it more visible and, above all, to provide an ecosystem for its growth.
The reputation mechanism designed and implemented consists of a Blockchain (Hyperledger
Fabric) infrastructure for EERIS - EERIS Blockchain Infrastructure (EBI), which communicates with
the platform through an API (Application Programming Interface).
The reputation factor will result by weighting the dynamics of the RI data stored on the
Blockchain, over time.
3. Blockchain-based Reputation Infrastructure
for Open Research: design and implementation
Proposed solution
The aim of the project is to create a reputation system which can be integrated with the
current EERIS platform without the need to redesign or revamp the whole platform, thus a
set of APIs which can be integrated with the current platform was proposed in 2 steps:
1. Integrate existing functionality on the platform with the designed Blockchain system to
build dynamism through the traceability of the activities of each RI based on which the
reputation is build.
2. Integrate certifications of data contributed through collaborations of the RIs and
multiparty contracts.
The storage of data (1) / interaction (2, 3, 4) of the research infrastructures (RI) on
Blockchain ensures:
1. immutability, transparency, traceability and audit of
data / collaborations stored for each RI at certain
periods of time or when changes appear for the
number of experts, equipment, services, and visits;
thus, the dynamics of each RI are retained
2. registration and dynamics of contracts for
technology transfer with other RIs and third parties
3. openness of research by publishing open data sets
for reuse in other projects by other RIs, entities
4. copyright protection / certification / licensing /
notarization – by storing certificates for articles,
data, projects, open educational resources, training,
internships, milestones, etc.
EERIS Blockchain Infrastructure (EBI)
- The PoC network consist of 2
organizations, each having their
own Certificate Authorities,
Peers, Orderers;
- The network runs a RAFT
ordering service and a channel
containing 2 chaincodes for the
RIs and separately for
certificates is being used.
- A service exposing endpoints
for interacting with the network
as well as managing identities
and IPFS pinning.
EERIS Reputation
Mechanism
Swagger has been used to describe the
APIs.
To further showcase the functionalities
a dashboard interface has been built.
The implemented EERIS Blockchain Infrastructure (EBI) was presented, analyzed and piloted with
representatives of three universities:
a) Politehnica University of Timișoara (UPT) - Lecturer Dr. Vlad Mihăescu, Director of the Center
for Innovation and Technology Transfer – for creating and tracing a technology transfer
contract between the center and a company;
b) West University of Timișoara (UVT) - Lecturer Dr. Cristian Cira, coordinator of the
Postgraduate Program “Entrepreneurship in Blockchain” – for storage and verification of a
document on Blockchain, respectively of the certificate of completion of the postgraduate
program;
c) “Vasile Goldiș” University of Arad (UVVG) - Assoc. Prof. Antoanela Naaji, Director of the
International Relations Department – for storage and open access to technical or medical
research data for participants in international webinars.
The piloting has demonstrated the interest of the universities for the new EERIS facilities issued
by EBI and that they would be included in the current activities, for contracts with third parties,
research projects for open access to research data, programs for which the certificates of
completion are stored on the Blockchain.

• Reputation total = 455
6.2. Modelling the Reputation factor –
updated version
The implemented reputation mechanism aims to increase openness, impact, and technology transfer of
research infrastructures (RIs) and is designed not only to measure reputation, but also to make it more visible
and, above all, to provide an ecosystem for its growth.
The EBI infrastructure is flexible and extensible, to which all or only a part of the research infrastructure (RIs)
can be connected, for piloting and familiarization. EBI could also be installed for individual or groups of
research or academic institutions.
EBI ensures the immutability, traceability, and audibility of RI data. In this way, the stored open research data
meets the principle of FAIR (Findable, Accessible, Interoperable, and Re-usable), and data storage and
management being performed according to the principle of TRUST (Transparency, Responsibility, User focus,
Sustainability, and Technology) (Lin et al ., 2020).
Future work requires a more extensive performance analysis based on a set of different network settings and
distribution of nodes.
Also, the implemented system can ensure open access to the scientific results (including data) of the RI, and in
the future, the mechanisms could be used also for the evaluation, classification, ranking, financing, and
matching partners.
For further expanding the network and bridging the information into other applications (eg. Brainmap – online
community for researchers), a SSI management system needs to be integrated for sharing identities across
platforms (eg. TrustID, Hyperledger Aries).
The activities towards open research/data on EERIS could contribute to the scientific portfolios of the
academics/researchers and be taken into account for promotion.

Building a Blockchain-based Reputation Infrastructure for Open Research. Case study: the EERIS Network

  • 1. Building a Blockchain-based Reputation Infrastructure for Open Research.

  • 3. Scope: Development of a Reputation Mechanism for Research Infrastructures, integrated with EERIS Project “Increasing the capacity of the RDI system to respond to global challenges. Strengthening the anticipatory capacity for evidence-based public policy making - SIPOCA 592”, UEFISCDI. EERIS.eu: Engage in the European Research Infrastructures System - developed and hosted by the Executive Agency for Higher Education, Research, Development and Innovation Funding (UEFISCDI) - a booking gate where specialists and companies can engage with public and private European research infrastructures in order to carry out research, by interacting with services, equipment and experts. 1. EERIS Network description. Scope of the project
  • 4. Reputation is the recognition by other people/entities of some characteristic or ability (Merriam-Webster dictionary); Few attributes are more important to identity and trust than reputation (Arun and Carmichael, 2017); Reputation could be seen as a global perception of an entity's behavior based on the trust established by the other entities in a system. In order to guarantee an objective measurement of reputation, a reputation management system has to be designed: - a possible approach is to establish a central authority to act as the agent of trust, but such a solution does not eradicate the root cause of mistrust - another approach: a distributed reputation system based on Blockchain; to measure an individual’s or an institution’s propensity to do what they promise, data tracked for past performance on a Blockchain could be used, while access to the data on a Blockchain becomes a new verifiable basis for reputation, which can visibly demonstrate trustworthiness to their potential clients and partners. 2.1. Reputation The Blockchain is a type of Distributed Ledger Technology (DLT), an append-only chain-like data structure, made out of signed and timestamped blocks that contain the transactions (Holotescu and Vasiu, 2020).
  • 5. 2.2. Open Research Our approach follows the principles of Open Research/Science recently defined by UNESCO Recommendations on Open Science, European Union's Open Science policy, and Open Science Knowledge Hub Romania. UNESCO Recommendations on Open Science, published in November 2021: “Open science increases scientific collaborations and sharing of information for the benefits of science and society; also opens the processes of scientific knowledge creation, evaluation and communication to societal actors beyond the traditional scientific community.” Blockchain and Open Data share similar principles such as the promotion of transparency, equality in information knowledge and access, as well as the reorganisation of data exchange between a number of parties (data.europa.eu, 2018). The decentralization brought by Blockchain enables researchers to build their own open ecosystem for research data, metadata, and communication that follows the philosophy of open research, thus everyone can openly participate, collaborate, and contribute to science. The results of these activities, such as research data, processes, studies, and methods, are freely available so that they can be reused and reproduced (Leible et al., 2019).
  • 6. The implemented reputation mechanism aims to increase openness, impact, and technology transfer of research infrastructures (RIs) and is designed not only to measure reputation, but also to make it more visible and, above all, to provide an ecosystem for its growth. The reputation mechanism designed and implemented consists of a Blockchain (Hyperledger Fabric) infrastructure for EERIS - EERIS Blockchain Infrastructure (EBI), which communicates with the platform through an API (Application Programming Interface). The reputation factor will result by weighting the dynamics of the RI data stored on the Blockchain, over time. 3. Blockchain-based Reputation Infrastructure for Open Research: design and implementation
  • 7. Proposed solution The aim of the project is to create a reputation system which can be integrated with the current EERIS platform without the need to redesign or revamp the whole platform, thus a set of APIs which can be integrated with the current platform was proposed in 2 steps: 1. Integrate existing functionality on the platform with the designed Blockchain system to build dynamism through the traceability of the activities of each RI based on which the reputation is build. 2. Integrate certifications of data contributed through collaborations of the RIs and multiparty contracts. The storage of data (1) / interaction (2, 3, 4) of the research infrastructures (RI) on Blockchain ensures: 1. immutability, transparency, traceability and audit of data / collaborations stored for each RI at certain periods of time or when changes appear for the number of experts, equipment, services, and visits; thus, the dynamics of each RI are retained 2. registration and dynamics of contracts for technology transfer with other RIs and third parties 3. openness of research by publishing open data sets for reuse in other projects by other RIs, entities 4. copyright protection / certification / licensing / notarization – by storing certificates for articles, data, projects, open educational resources, training, internships, milestones, etc.
  • 8. EERIS Blockchain Infrastructure (EBI) - The PoC network consist of 2 organizations, each having their own Certificate Authorities, Peers, Orderers; - The network runs a RAFT ordering service and a channel containing 2 chaincodes for the RIs and separately for certificates is being used. - A service exposing endpoints for interacting with the network as well as managing identities and IPFS pinning.
  • 9. EERIS Reputation Mechanism Swagger has been used to describe the APIs. To further showcase the functionalities a dashboard interface has been built.
  • 10. The implemented EERIS Blockchain Infrastructure (EBI) was presented, analyzed and piloted with representatives of three universities: a) Politehnica University of Timișoara (UPT) - Lecturer Dr. Vlad Mihăescu, Director of the Center for Innovation and Technology Transfer – for creating and tracing a technology transfer contract between the center and a company; b) West University of Timișoara (UVT) - Lecturer Dr. Cristian Cira, coordinator of the Postgraduate Program “Entrepreneurship in Blockchain” – for storage and verification of a document on Blockchain, respectively of the certificate of completion of the postgraduate program; c) “Vasile Goldiș” University of Arad (UVVG) - Assoc. Prof. Antoanela Naaji, Director of the International Relations Department – for storage and open access to technical or medical research data for participants in international webinars. The piloting has demonstrated the interest of the universities for the new EERIS facilities issued by EBI and that they would be included in the current activities, for contracts with third parties, research projects for open access to research data, programs for which the certificates of completion are stored on the Blockchain. 4.

Modelling the Reputation factor – updated version
  • 18. The implemented reputation mechanism aims to increase openness, impact, and technology transfer of research infrastructures (RIs) and is designed not only to measure reputation, but also to make it more visible and, above all, to provide an ecosystem for its growth. The EBI infrastructure is flexible and extensible, to which all or only a part of the research infrastructure (RIs) can be connected, for piloting and familiarization. EBI could also be installed for individual or groups of research or academic institutions. EBI ensures the immutability, traceability, and audibility of RI data. In this way, the stored open research data meets the principle of FAIR (Findable, Accessible, Interoperable, and Re-usable), and data storage and management being performed according to the principle of TRUST (Transparency, Responsibility, User focus, Sustainability, and Technology) (Lin et al ., 2020). Future work requires a more extensive performance analysis based on a set of different network settings and distribution of nodes. Also, the implemented system can ensure open access to the scientific results (including data) of the RI, and in the future, the mechanisms could be used also for the evaluation, classification, ranking, financing, and matching partners. For further expanding the network and bridging the information into other applications (eg. Brainmap – online community for researchers), a SSI management system needs to be integrated for sharing identities across platforms (eg. TrustID, Hyperledger Aries). The activities towards open research/data on EERIS could contribute to the scientific portfolios of the academics/researchers and be taken into account for promotion. 7. Conclusions and future work
