Overview

The Workflow Engine is the foundational infrastructure of DOVU OS, designed to serve both project developers creating supply and demand-side actors querying credits to meet their specific needs. It acts as a core system for managing workflows, data, identity, and tokenized assets, while also functioning as a data warehouse for demand-side insights.

By seamlessly connecting supply creation with demand insights, the Workflow Engine provides the tools needed to build scalable, high-integrity ecosystems for environmental credits and tokenized assets.

This dual role makes the Workflow Engine the backbone of DOVU OS:

  1. For Project Developers: A platform to onboard, manage, and issue credits with full compliance and traceability.

  2. For Demand-Side Actors: A query system for enterprises and buyers to connect with credits tailored to their goals and regulatory obligations.

DOVU works with clients to fully understand their business requirements, particularly in developing circular economies or managing specific projects tied to sustainability objectives. From these requirements, we map needs into schemas, data flows, and workflows within the system. Flexibility is paramount, enabling us to test and refine different use cases to deliver effective solutions.

In future releases of the system, developers and product teams will have this power within their own hands.

Use Case Example

The Challenge:

Supporting a circular economy for Original Equipment Manufacturers (OEMs) by reducing carbon emissions through verified government-backed Certificate of Deposits (CDs). Government-sanctioned recycling centers, such as Registered Vehicle Scrapping Facilities (RVSFs), invest additional time and care in the recycling process to minimize environmental impact. However, this higher standard of recycling incurs additional costs, which can only be offset through the creation of credits that are sold on marketplaces to generate additional revenue streams.

The Solution:

Using the DOVU Engine to onboard projects, manage data, and issue tokenized ELV credits. These credits are generated through RVSFs and tied directly to emissions reductions. OEMs can leverage these credits to provide retail discounts for customers, closing the loop between emissions reduction and consumer benefits. By tokenizing these processes, the system ensures compliance, traceability, and scalability for all participants in the ecosystem.

Key Features of the Workflow Engine

  1. Supply Creation for Developers

    • Onboard projects and issue credits using prebuilt workflows connected to Hedera Guardian policies.

    • Schema validation ensures compliance and traceability for all data submissions.

  2. Demand-Side Data Warehouse

    • Enterprises can query available credits based on type, volume, or geography to align with sustainability and Scope 3 goals.

    • Demand signals feed directly into workflows, ensuring the supply aligns with real-time market needs.

  3. Integrated Workflows and Actors

    • Assign roles dynamically and connect actors to workflows, mirroring real-world processes like verifications and approvals.

  4. End-to-End Lifecycle Support

    • Manage everything from data onboarding to credit issuance and marketplace integration, creating a seamless credit lifecycle.

A Proven System, Solving Problems

DOVU’s Workflow Engine has already been used to support high-impact projects, from sustainability initiatives to data-heavy regulatory use cases. With the Developer Preview, external developers can now:

  • Access and experiment with prebuilt workflows.

  • Issue testnet credits and manage actors.

  • Understand how the Workflow Engine bridges demand-side signals with supply-side action.

Looking forward, the Workflow Engine will expand to include:

  1. Custom Workflow Creation: Developers will soon be able to design and publish their own workflows, enabling unique use cases.

  2. Advanced Data Integration: Future iterations will include more modular features and expanded integrations, making the system adaptable for even more industries.

Next Steps

Start exploring the Workflow Engine today:

  1. Experiment with Prebuilt Workflows: Test workflows designed to streamline credit creation and management.

  2. Dive into the API Documentation: Understand how to interact with workflows, roles, and credit issuance processes.

  3. Issue Testnet Credits: Simulate the full lifecycle of credit creation and validate how data and actors interact.

The Workflow Engine’s versatility is exemplified by its role in the .
