Building Trust in Content with Blockchain Technology

In the digital world, trust is the cornerstone of content consumption. The TruBlo project is at the forefront of this challenge, leveraging blockchain technology to ensure the creation of trustable content. With an ever-increasing volume of information online and the challenges posed by new technologies, such as generative AI that can lead to issues like automated propaganda, blockchain's role in this endeavor is pivotal, providing a decentralized and secure framework and offering a solution to the growing concerns around misinformation and the authenticity of digital content.

The TruBlo project has achieved significant technological milestones, fostering innovation and tangible technological progress in areas crucial for ensuring trust and reliability in digital content. One of the key achievements includes the development of demonstrators and Minimum Viable Products (MVPs) that address the challenges identified within TruBlo's focus areas. These MVPs have been instrumental in showcasing the practical application of blockchain technology in sectors such as agriculture, retail, aviation, and media.

Gauging Innovation: The Readiness Levels of TruBlo

The TruBlo project has integrated the KTH Innovation Management Methodology, which has been instrumental in recording how the 45 funded projects handle innovation. This methodology encompasses seven readiness levels, including the TRL and the Scientific Readiness Level (SRL), which reflect the maturity of technologies and scientific advancements respectively. The additional five readiness levels—Customer Readiness Level (CRL), Business Model Readiness Level (BRL), IPR Readiness Level (IPRL), Team Readiness Level (TMRL), and Funding Readiness Level (FRL)—ensure a holistic view of each project's development. These levels help confirm customer interest, establish financial and environmental viability, clarify legal and IP situations, align team competencies, and secure necessary funding. This structured approach has enabled TruBlo-funded projects to achieve beyond-the-state-of-art status, creating novel technologies and MVPs with high technological and scientific value.

The TruBlo Project's Open Call Methodology

The TruBlo project built its innovative ecosystem by conducting three open calls, which were instrumental in selecting 45 projects for funding out of more than 300 received proposals. The selection process was designed to identify and support the most promising initiatives in the realm of trust and blockchain. Each call followed a multi-phase evaluation methodology, including eligibility checks, external expert evaluations, and a consensus meeting to ensure a fair and transparent process. The chosen projects not only demonstrated exceptional potential in advancing blockchain technology for trustable content but also aligned with TruBlo's strategic objectives and the broader goals of the Next Generation Internet initiative.

The TruBlo project's funding framework was strategically divided into two distinct phases to optimize the development and impact of the selected initiatives. Phase 1, the 'Feasibility Phase,' was designed to support the 45 projects in exploring the viability of their ideas, conducting market analysis, and developing initial prototypes. This phase was crucial for setting the foundation for further innovation. Subsequently, 9 projects out of the 45 projects were selected to go to Phase 2, the 'Implementation Phase,' focused on advancing the projects that successfully demonstrated their potential in Phase 1. This two-phase approach ensured that only the most promising projects with a clear path to market and societal impact received additional support to bring their solutions to completion.

Success Stories: Third-Party Projects and Their Achievements

The supported 45 third-party projects have made significant strides in their respective fields, demonstrating the power of blockchain technology to address real-world challenges. From them, the 9 phase-2 projects notable success stories stand out for their scientific results and developed demonstrators.

FAKE: This project tackles the pervasive issue of fake news by developing a system using blockchain technology designed to debunk fake news before it spreads. FAKE provides a digital content authority proof, which has shown effectiveness in simulations for identifying fake news and malicious sources.

LedgeAir: Focused on the aviation industry, LedgeAir aggregates and analyzes radio messages to improve awareness about aircraft, passengers, cargo, routes, fuel, and maintenance, leading to optimized operations, safety, and efficiency, ensuring also strict adherence to safety regulations and leveraging data analysis for better decision-making.

OttCT: This project has developed a blockchain-based solution to ensure the authenticity and integrity of over-the-top (OTT) content. By creating a transparent and tamper-proof system, OttCT provides a way for content creators and distributors to protect their intellectual property and for consumers to verify the legitimacy of the content they consume.

POSER: POSER has focused on enhancing the reliability of social media content by developing a blockchain-based system for content verification. This project aims to empower users to distinguish between genuine and manipulated content, thereby fostering a more trustworthy social media environment.
