2.1.3 Case Selection

Blockchain technology finds wide application in various domains such as monitoring/traceability systems, distributed financial systems (DeFi), loyalty systems, ecosystems, and solutions focused on data quality tracking. While any blockchain system can be adapted for these purposes, DGT stands out due to its unique architectural features and technologies, enabling the formation of a range of preferred use cases.

DGT is particularly well-suited for solutions where:

• A complex network structure is required, with different permission levels for data access (security contours). DGT allows for the creation of intricate network configurations that cater to specific security and access requirements.

• A hybrid solution is desired, combining elements of public access with partially or fully closed networks. DGT provides the flexibility to integrate public and private segments within the same ecosystem, allowing organizations to strike a balance between transparency and confidentiality.

• The system involves a significant number of participants and handles a large volume of transactions, necessitating high bandwidth. DGT's architecture and consensus mechanism are designed to support scalability and accommodate a high transaction throughput.

• There are stringent requirements for system integration with corporate applications and a need for relatively low transaction costs. DGT offers seamless integration capabilities with existing corporate infrastructures and employs efficient consensus mechanisms, resulting in cost-effective transaction processing.

Several areas combine application tasks, taking into account the opportunities offered by Web 3.0 with an emphasis on tokenization and privacy:

• Supply Chain and Vertical Integration. This group focuses on enhancing supply chain management, improving traceability, and enabling seamless collaboration across vertical integration networks. Blockchain initiatives in this group aim to address challenges such as product provenance, inventory management, and transparent value chains. Examples of blockchain initiatives in this space include supply chain traceability for food products (IBM Food Trust), authentication of luxury goods (Everledger Platform), and distributed inventory management for the aviation industry (Amazon Aircraft parts provenance).

• Innovative Financial Services. This group explores the potential of blockchain in revolutionizing financial services, particularly in areas such as tokenization, crowdfunding, decentralized payment solutions, and the NFT market. Blockchain initiatives within this group aim to enable efficient and secure financial transactions, create new investment opportunities, and democratize access to financial services. Examples include real-world asset tokenization (RealBlocks, Aurus), decentralized crowdfunding platforms (Gitcoin), and the development of virtual payment cards (Veem, Moon) within Neobanks (Cogni, Hi.com, Robinhood).

• Decentralized Green Energy Market. This application group focuses on leveraging blockchain technology to drive the transition to clean and sustainable energy systems. Blockchain initiatives within this group aim to facilitate peer-to-peer energy trading, promote green energy initiatives, and support carbon offset programs. Examples include micro-grid energy trading platforms (Suncontract), platforms for tracking and offsetting carbon footprints (KlimaDAO, Terrapass), and decentralized energy marketplaces (Powerledger, LO3Energy).

• B2B2C Ecosystems and Horizontal Integration. This group explores the potential of blockchain in enabling seamless collaboration and value exchange within B2B2C ecosystems. Blockchain initiatives within this group aim to enhance data sharing, enable decentralized marketing attribution, and build distributed loyalty platforms. Examples include distributed KYC and user scoring systems (PLOS ONE, xHashtag, FractalId, Protokol), decentralized marketing attribution platforms, and decentralized publishing platforms for data exchange.
