Integration of Holochain, hREA/ValueFlows, and Cardano in Open Value Networks

Work in Progress

This is a work in progress and is not ready to be published yet.

The integration of Holochain, hREA/ValueFlows, and Cardano offers a groundbreaking approach for Open Value Networks (OVNs) engaged in peer production, particularly within the context of open-source, Do-It-Yourself (DIY) projects like PEP Master. By combining Holochain’s decentralized contribution tracking, hREA/ValueFlows’ economic modeling, and Cardano’s robust blockchain infrastructure, this hybrid model enables distributed fabrication, secure asset tokenization, and regulatory compliance for collaboratively produced therapeutic devices. This article explores how these technologies converge to support OVNs, with a specific focus on the PEP Master project, its objectives, and the current implementation plan, as illustrated in the accompanying diagram.

• Open Value Networks are a type of peer production network that are characterized by their focus on value distribution and the use of blockchain technology to support their operations.
• Holochain offers an agent-centric architecture that aligns with self-sovereignty and peer-to-peer collaboration, allowing participants to maintain control over their data while contributing to a shared network.
• hREA/ValueFlows provides a standardized vocabulary for tracking economic activities (Resources, Events, Agents), ensuring transparent and auditable records of contributions and value flows.
• Cardano brings a secure blockchain layer for tokenization, certification, and economic incentives, supporting distributed ownership and global accessibility through its smart contract capabilities.

This synergy creates a robust ecosystem for OVNs, enabling them to manage complex workflows, reward contributors fairly, and ensure compliance with regulatory standards—a critical requirement for projects like PEP Master.

Core OVN Principles and the Role of Technology

Open Value Networks operate on principles that recognize value as a complex, triadic relationship between valuables (realities), tokens (symbolic representations), and valuations (both subjective experiences and inter-subjective shared meanings). Unlike traditional economic models that treat value as a tangible commodity that can be created, stored, or transferred, OVNs understand that value fundamentally rests on “subjective experiences that move human beings into action”. This perspective avoids value fetishism and shapes how technology is employed within the network.

OVNs also embrace a more complex approach to ownership, recognizing multiple forms of property relations including private, shared, commons, and notably, “nondominium” - assets that by their nature cannot be owned. For instance, while individual components of the network may be privately owned or held in commons, the network’s emergent capabilities often exist as nondominium, similar to how the Bitcoin network itself transcends traditional ownership models.

Openness and Transparency

OVNs prioritize open access to information, processes, and decision-making. This transparency extends to contribution tracking, resources flows, and governance, ensuring that all participants can audit and verify activities. Holochain’s distributed hash table (DHT) and hREA/ValueFlows’ transparent logging of economic events (Resources, Events, Agents) support this principle by providing auditable records of all interactions within the network.

Nondominium and Diverse Property Regimes

OVNs embrace a variety of property regimes, including private, shared, commons, and public, but they also introduce the concept of nondominium—assets that, by their nature, cannot be owned or controlled. For example, the Bitcoin Network operates as a nondominium: it exists as an aggregated entity providing token exchange services, but if any individual or group gains enough influence to control it, the network dissipates due to loss of trust. In contrast, mining computers are privately owned, and the Bitcoin code exists as a commons. Cardano’s blockchain complements this by tokenizing assets (e.g., NFTs for certified designs) that can exist under various property regimes, while Holochain ensures that the network itself remains a nondominium, fostering trust and decentralization.

Meritocratic Governance

Access to decision-making in OVNs is based on contributions rather than hierarchical power structures. Holochain’s agent-centric architecture supports this by accurately tracking individual contributions via hREA/ValueFlows, ensuring that influence is distributed based on merit. Cardano’s smart contracts further enable merit-based reward systems, linking contributions to token rewards.

Value as a Triadic Relation

OVNs redefine value as a triadic relation between a valuable (a reality), a token (a symbol, which may or may not be monetary), and a valuation (a subjective and inter-subjective experience shaped by culture and socialization). Value is not a thing that can be created, stored, or transferred; rather, it emerges from subjective experiences that move individuals to action. This perspective avoids value fetishism and emphasizes the relational nature of economic interactions. hREA/ValueFlows captures this by modeling economic events and processes as relational flows, while Cardano’s token reward system provides symbolic tokens that reflect these valuations, ensuring rewards align with the subjective and inter-subjective value perceived by the network.

Modularity and Interoperability

OVNs embrace modular designs and interoperable systems to ensure flexibility and scalability. Holochain’s customizable application framework supports this by allowing tailored solutions for specific use cases, while Cardano’s interoperability with decentralized storage solutions like Iagon ensures seamless integration with other systems.

Holochain’s modular architecture, built on Zomes and DNA, provides core composability features that integrate with Moss and Neighborhood as building blocks for collaboration and social sensemaking. This architectural approach enables flexible and adaptable solutions for different use cases.

Cardano complements this modularity through its cross-chain and cross-platform interoperability capabilities. A future Cardano Zome will enable direct integration with Holochain, while Cardano’s native interoperability with other blockchains (demonstrated through BitcoinOS and FluidToken) leverages the robustness of its EUTXO transaction model and the Inter-Blockchain-Protocol (IBP).

Global Accessibility

OVNs aim to create networks that transcend geographical boundaries through a “glocal” (global + local) approach. Cardano’s blockchain enables transactional global interoperability via its smart-contracts system, while Holochain provides local context and governance through its agent-centric architecture. This hybrid model allows contributors to transport their credentials and reputation across different OVNs seamlessly.

The integration of Holochain with ADAM (https://coasys.org/adam) establishes a common language and perspective for translating local credentials, while Cardano secures the cross-network transaction of these credentials and reputations. ADAM’s meta-ontology, which defines three classes (Agents, Languages, and Perspectives), creates a spanning layer that enables many-to-many mappings between user interfaces and existing web technologies. This architecture allows for private, locally stored graph databases that associate data across different Languages while maintaining global interoperability.

Sustainability

OVNs prioritize environmentally and economically sustainable practices. Holochain’s energy-efficient architecture aligns with this principle by minimizing the environmental impact of peer production networks, while Cardano’s Ouroboros Proof-of-Stake (PoS) consensus mechanism ensures long-term sustainability through a more energy-efficient consensus mechanism than Proof-of-Work (PoW) or other PoS mechanisms used by other blockchains.

Holochain’s agent-centric architecture fundamentally differs from traditional blockchain approaches by eliminating the need for global consensus. Instead of all nodes processing all transactions, each agent maintains their own local chain and only validates the data they need. This distributed validation approach dramatically reduces computational overhead and energy consumption. The system scales linearly with the number of users, rather than exponentially like traditional blockchains, making it inherently more energy-efficient.

Cardano’s Ouroboros protocol represents a significant advancement in sustainable blockchain technology. Unlike energy-intensive Proof-of-Work systems, Ouroboros achieves the same security guarantees while consuming only a fraction of the energy. Research indicates that Cardano’s energy consumption is approximately 0.01% of Bitcoin’s, using about 6 GWh annually compared to Bitcoin’s 110.53 TWh. This efficiency is achieved through:

• Stake-based validator selection instead of computational puzzles
• Deterministic block creation process
• Efficient network communication protocols
• Optimized transaction validation

The combination of Holochain’s agent-centric architecture and Cardano’s Ouroboros protocol creates a highly sustainable infrastructure for OVNs, enabling them to scale their operations without compromising environmental responsibility.

Peer-to-Peer Collaboration

OVNs emphasize direct interactions between participants, reducing reliance on intermediaries. Holochain’s peer-to-peer networking capabilities enable real-time collaboration, while Cardano ensures secure and transparent transactions without centralized control.

Continuous Innovation

OVNs model is in continuous improvment/evolution, iteratively improving through the current societal and technological transitions. Holochain, by it’s lack of censensus mechanisme bring the necessary flexiblity for the OVNs model to evolve and experiment in pararel in different economic contexte like a living economic-lab. Cardano, bring the transactional backbone with its structured data and financial architecture. It’s a global security that allow local experimentations with HOlochain communities. It’s the perfect hybridation between data and agent centricity.

Each OVN can have its own local economic model, enable by Holochain and hREA/Valueflows and then the global Cardano smart contract architecture can make the connection and validation at a global level.

ADAM (https://coasys.org/adam) could be a bridge between the OVNs and the Cardano smart-contracts. It’s a meta-ontology defining 3 classes: Agents, Languages and Perspectives. These form a spanning-layer that enables many-to-many mappings between user-interfaces (i.e. apps) and existing web technologies wrapped in “Languages”. Apps interface with “Perspectives” which are private and locally stored graph databases associating data across different Languages.

Global Accessibility

OVNs aim to create networks that transcend geographical boundaries. Cardano’s blockchain enables transactional global interoperability via its smart-contracts system, while Holochain provide the local context and governance via it’s agent-centric architecture. It’s a mix between local and global (Glocal). Contributors to a local OVN can transport their credentials and reputation to facilitate their access to other OVNs.

Holochain + ADAM favorize the translations of those local credential by establishing a common language/perspective while Cardano secure the transactions of theses credetentials and reputations across the local networks.

Self-Sovereignty

OVNs respect the autonomy of individual contributors, allowing them to maintain control over their data and contributions. Holochain’s agent-centric design ensures that participants retain sovereignty over their personal data, while Cardano’s decentralized identity (DID) zone supports secure and self-sovereign identity management.

By adhering to these principles, OVNs create ecosystems that foster collaboration, innovation, and equitable economic interactions. The integration of Holochain, hREA/ValueFlows, and Cardano provides a technical foundation that not only supports but also amplifies these principles, enabling OVNs to operate effectively in contexts like the PEP Master project, where transparency, fairness, and regulatory compliance are critical.

The PEP Master Context

PEP Master is an open-source DIY therapeutic device and game developed by a consortium involving Sensorica, Sainte Justine Hospital, Breathing Games and Ludociels. The project aims to increase accessibility to medical and therapeutic equipment by leveraging peer production and Web3 technologies. The primary objectives include:

1. Achieving ISO standards for the PEP Master device.
2. Validating the clinical relevance of peer-produced PEP Master devices through medical research.
3. Establishing validation and certification methods for device blueprints and fabrication processes.
4. Implementing secure medical data storage and transfer mechanisms.
5. Engaging with governmental agencies like Health Canada for regulatory approval.

The PEP Master project operates within a niche where quality, safety, and regulatory compliance are paramount. Traditional economic models often fail to effectively address rare medical conditions. To overcome this limitation, the PEP Master project implements a trust-based economic model that leverages open collaboration and distributed fabrication. This approach increases accessibility to medical devices, making it particularly valuable for addressing marginalized or niche rare medical conditions.

The hREA/ValueFlows Framework

hREA (Holochain Resource-Event-Agent) implements the ValueFlows specification, a standardized vocabulary for describing economic activities in decentralized networks.

The Hybrid Model: Holochain + Cardano in Action

The integration of Holochain and Cardano creates a hybrid model that leverages the strengths of both technologies to support the PEP Master workflow. The process is illustrated in the following diagram:

The diagram outlines the following steps:

1. Design Submission and Contribution Logging (Holochain): Engineers and designers submit designs through the Holochain application, where contributions are logged using hREA/ValueFlows. The backend stores design data in a distributed hash table (DHT) for transparency.
2. Validation Process (Holochain + Cardano): Validators (e.g., doctors) review designs on Holochain, and once validated, the process triggers Cardano to mint an NFT for certification.
3. Certification Process (Cardano): Cardano’s smart contracts manage the certification, creating an NFT (using CIP-25/68 standards) that represents the validated design, ensuring legal recognition.
4. Fabrication and Distribution (Holochain + Cardano): The certified design is sent to fabricators (e.g., makerspaces), with Cardano managing the chain of trust for material artifacts.
5. Therapeutic Use and Data Management (Holochain): Patients use the PEP Master device, and game clients report sensitive data (e.g., health outcomes) to a private DHT zone on Holochain, ensuring privacy.
6. Research Export (Holochain): Anonymized data is exported for public research, maintaining compliance with privacy regulations.
7. Token Reward System (Cardano): Contributors receive tokens based on their logged contributions, incentivizing participation and sustaining the network.
8. Forking and Iteration (Holochain): Designs can be forked and remixed on Holochain, fostering continuous innovation.

This hybrid model ensures that PEP Master achieves its goals of transparency, regulatory compliance, and fair value distribution while fostering a sustainable peer production ecosystem.

Current Plan and Next Steps

The PEP Master project is currently in the prototyping phase, with the following milestones:

• Prototype Development: The team is building a functional prototype integrating Holochain and Cardano, as outlined in the diagram. This includes the user interface for doctors and patients, the backend for contribution tracking, and Cardano’s smart contracts for certification and rewards.
• Regulatory Engagement: The consortium is engaging with Health Canada to secure regulatory approval, using the hybrid model to demonstrate compliance with ISO standards and safety requirements.
• Data Storage and Privacy: The project is implementing a data storage prototype using Holochain’s DHT and Cardano’s Iagon integration, ensuring secure handling of sensitive patient data.
• Community Building: Sensorica and its partners are fostering a community of contributors, including engineers, doctors, and patients, to participate in the OVN and refine the PEP Master device through iterative design.

The next steps include testing the prototype in a real-world setting at Sainte Justine Hospital, gathering feedback from patients and doctors, and iterating on the design. The team also plans to expand the token reward system to attract more contributors, ensuring the long-term sustainability of the project.

Future Outlook

The integration of Holochain, hREA/ValueFlows, and Cardano offers a transformative framework for Open Value Networks like PEP Master. By combining Holochain’s scalable, agent-centric architecture with hREA/ValueFlows’ transparent economic modeling and Cardano’s secure blockchain capabilities, the project creates a comprehensive ecosystem for peer production. This model not only addresses the challenges of quality, safety, and regulatory compliance in medical device production but also paves the way for a self-sustaining p2p economy.

As the PEP Master project progresses, it has the potential to set a precedent for other peer-produced medical devices, demonstrating how Web3 technologies can empower communities to innovate, collaborate, and create value equitably. The hybrid model of Holochain and Cardano could inspire broader adoption of OVN principles, fostering resilient and sustainable economic systems that prioritize cooperation and shared value creation in the digital age.
