Design and Implementation of a Distributed Ledger Technology Platform to Support Customs Processes within Supply Chains

In international trade, customs clearance fulfills complex and country-specific tasks in the execution of supply chain processes. Importers and exporters have to integrate customs authorities into the information flow, as customs authorities require information, e.g., on the bill of lading and the commercial invoice apart from the customs declaration. In addition, involved sub-service providers increase the problem of information asymmetry and the required coordination effort. Practice and research consider Distributed Ledger Technology (DLT) as a potential solution since this technology maintains a mutually agreed and secure database of value-creation partners. However, research has hardly investigated the design of such DLT systems. Therefore, we present a requirements catalogue, a concept, and a prototype of a DLT platform to address the outlined problem of information asymmetry, especially with a focus on customs processes

Design of a software architecture supporting business-to-government information sharing to improve public safety and security: Combining business rules, Events and blockchain technology

Toensurepublicsafetyandsecurity,itisvitallyimportantforgovernmentstocol- lect information from businesses and analyse it. Such information can be used to determine whether transported goods might be suspicious and therefore require physical inspection. Although businesses are obliged to report some information, they are reluctant to share addi- tional information for fear of sharing competitively sensitive information, becoming liable and not being compliant with the law. These reasons are often overlooked in the design of software architectures for information sharing. In the present research, we followed a design science approach to develop a software architecture for business-to-government information sharing. Based on literature and a case study, we elicited the requirements an architecture that provides for the sharing of information should meet to make it acceptable to businesses. We then developed the architecture and evaluated it against the requirements. The architec- ture consists of a blockchain that stores events and rules for information sharing that are controlled by businesses. For each event, two parties use their private keys to encrypt its Merkle root to confirm that they know the data are correct. This makes it easy to check whether information is reliable and whether an event should be accepted. Access control, metadata and context information enable the context-based sharing of information. This is combined with the encryption and decryption of data to provide access to certain data within an organisation.Organisation and GovernanceInformation and Communication Technolog

Blockchain for digital government

In less than ten years from its advent in 2008, the concept of distributed ledgers has entered into mainstream research and policy agendas. Enthusiastic reception, fuelled by the success of Bitcoin and the explosion of potential use cases created high, if not hyped, expectations with respect to the transformative role of blockchain for the industry and the public sector. Growing experimentation with distributed ledgers and the emergence of the first operational implementations provide an opportunity to go beyond hype and speculation based on theoretical use cases. This report looks at the ongoing exploration of blockchain technology by governments. The analysis of a group of pioneering developments of public services shows that blockchain technology can reduce bureaucracy, increase the efficiency of administrative processes and increase the level of trust in public record keeping. Based on the state-of-art developments, blockchain has not yet demonstrated to be either transformative or even disruptive innovation for governments as it is sometimes portrayed. Ongoing projects bring incremental rather than fundamental changes to the operational capacities of governments. Nevertheless some of them propose clear value for citizens. Technological and ecosystem maturity of distributed ledgers have to increase in order to unlock the transformative power of blockchain. Policy agenda should focus on non-technological barriers, such as incompatibility between blockchain-based solutions and existing legal and organizational frameworks. This principal policy goal cannot be achieved by adapting technology to legacy systems. It requires using the transformative power of blockchain to be used to create new processes, organizations, structures and standards. Hence, policy support should stimulate more experimentation with both the technology and new administrative processes that can be re-engineered for blockchain.JRC.B.6-Digital Econom
