DataPorts Blockchain Overview
- 1. An Overview of Blockchain Technology in DataPorts Thessaloniki Port Authority SA (ThPA) & Centre for Research and Technology, Hellas (CERTH)
- 2. Presentation layout 2 Section Slide colour code Introduction to DataPorts Overview of the Data Governance component Overview of the Container Pick-Up use case for ThPA
- 3. What is DataPorts? 3 Take advantage of the huge amount of data generated around highly digitalized & connected seaports Industrial data platform where data coming from different sources can be combined to improve existing processes Establish novel cognitive and AI-based applications Enable new business models
- 4. 4 Overview Project title: DataPorts – Data Platform for the Connection of Cognitive Ports Programme: H2020-EU.2.1.1. – INDUSTRIAL LEADERSHIP – Leadership in enabling and industrial technologies – Information and Communication Technologies (ICT) Topic: ICT-13-2018-2019 – Supporting the emergence of data markets and the data economy Contract Number: 871493 EC funding: 5.740.586,63 € Duration: 1 January 2020 – 31 December 2022 Project Coordinator: INSTITUTO TECNOLOGICO DE INFORMATICA, University of Valencia

- 7. DataPorts functionality 7 Data exchange, governed by permissions defined in a Data Governance component AI and analytics services Data sharing among stakeholders on a local port level (e.g. ThPA-centric, VPF-centric etc) through local use cases Blockchain technology is at the core of Data Governance and of certain Data Sharing applications
- 8. Blockchain in Maritime 8 Fuel Quality Traceability and Assurance: can help in reducing the emissions effects (pollution, health issues) Shipment Tracking: The traditional tracking is done with paperwork and involves numerous parties in the process. In blockchain, the documents are digital and can be retrieved at any time Smart Bills of Lading: A decentralized, traceable, and immutable system based on blockchain can make B/L accessible to all the parties Smart Contracts: Automation and security can be provided by smart contracts speeding up the whole process

- 12. Data Governance technical objectives (1/2) 12 Data Governance is the mechanism that enables a high-quality handling of access to data. It increases consistency and confidence in the registered data, improving data security and minimizing the risk of non compliance to relevant regulations. The inclusion of a blockchain network in DataPorts for data governance purposes aims to provide a comprehensive framework in which data ownership and data distribution policies become a relevant part of the entire DataPorts platform.
- 13. Data Governance technical objectives (2/2) 13 DataPorts provides a secured framework for data governance and data sharing for ports operations. More specifically, the blockchain ledger ensures: Full provenance of each transaction or access to data in the DataPorts platform. A non-repudiation process in case of dispute. Transparency, trackability, and traceability of transactions. Immutable single source of truth for all transactions.
- 14. Blockchain roles in DataPorts (1/2) 14 Blockchain for governance rules Blockchain for data sharing Blockchain manages consent of access to specific document/data Blockchain records transactions related to shared data and processes P2P data exchange Data sharing among participants in the business network Smart contract decides whether a participant is allowed to access a document based on the invoker’s credentials and access rules Smart contract records transactions related to shared data and processes of all participants in a business network
- 15. Blockchain roles in DataPorts (2/2) Blockchain for governance rules Blockchain for data sharing Immutability, auditability, provenance, transparency, traceability, trackability, and non- repudiation of access to information stored in owner’s repositories Immutability, auditability, provenance, transparency, traceability, trackability, and non-repudiation of information stored on the chain (all transactions related to this data) Generic component, part of the platform. Can be replicated in any domain. Specific to a certain use case. Can be replicated to similar processes in other ports 15
- 16. Technologies 16 Blockchain Network based on Hyperledger Fabric v 1.4.8 Hyperledger Fabric SDK for Node.js Storage state of transaction: CouchDB Smart contracts to allow/deny access to data and store transactions: Chaincode GO
- 17. 17 The Governance blockchain network is developed under the Hyperledger Fabric framework. All of its components follow the Hyperledger Fabric architecture model. Blockchain architecture (1/2)

- 19. Subcomponent layers 19 A network participant performs the role of data provider when it provides data to others and performs the role of data consumer when it collects data from others. Participants in the DataPorts ecosystem can potentially interact with the blockchain to perform any of these actions: upload metadata of a dataset and define the access rights to it, search for datasets and request access to an existing dataset, revoke access to an uploaded dataset, and view audit log of registration and access of datasets

- 21. 21 The goal: Improve the organization and management of the pickup and delivery of containers, with emphasis to land gate access. Added value: Improving the operational performance of the port supply chain, increasing visibility of operations for the stakeholders involved, while also improving the environmental burden caused by truck traffic.
