Building a Community-Owned Data Confidence Fabric With Distributed Ledgers and Smart Contracts

Explore the Transformative Power of Community-Driven Trust and Secure Data Monetization

In an era when data flows seamlessly across diverse decentralized systems and organizations, establishing trust and confidence in the data becomes paramount. Data from IoT devices, distributed applications, and edge servers cross multiple boundaries: trust zones, firewalls, networks, stakeholders, organizations, and geographies. No single entity in such an ecosystem can own the trust.

Project Alvarium is a Linux Foundation (LF) Edge project which aims to build an open-source framework and SDK for creating trust fabrics which deliver data from devices to applications with measurable confidence. Unlike a one-size-fits-all solution, the Alvarium framework empowers communities to construct their unique fabric with preferred technologies, cultivating a rich ecosystem of interoperable trust fabrics.

This presentation explores the transformative potential of a community-owned data confidence fabric (DCF) and trustworthy monetization of data using an open-source distributed ledger, Hedera network, and smart contracts. By embracing open-source principles, our solution not only ensures accessibility, but also encourages a diverse community of contributors to actively participate in refining and expanding the framework. This collaborative approach enhances the solution's robustness and aligns with our commitment to transparency, making the technology more trustworthy and widely adoptable in the broader open-source community. Topics include:

  • Insights from the Alvarium project
  • Demonstration of a DCF, both its construction and operation
  • How a decentralized approach to data confidence can empower individuals and organizations, promoting data sovereignty and mitigating risks associated with centralized control
  • Advantages and contributions the proposed framework offers to the open-source community, ranging from enhanced security and privacy to collaborative innovation

Part of the work being presented and demonstrated is based on a joint effort of multiple academic and industrial partners from the European Commission-funded CLEVER consortium. CLEVER is a research project which among other objectives aims to aid the adoption of open access and systematic use of open and standard interfaces. By engaging with the principles of open-source development, this presentation hopes to inspire FOSDEM’24 attendees to envision and actively participate in the creation of a community-owned DCF framework, fortifying the foundation of a more trustworthy and collaborative digital landscape.
