Decentralized Consulting AB (Kunveno Teknologos)

Multi 

Overview

The system leverages distributed ledger technology (DLT) to create a transparent, community-driven financial ecosystem. By eliminating reliance on centralized entities, all decisions, including protocol updates, are made collectively through on-chain proposal voting. Its infrastructure is entirely decentralized, covering both frontend and backend components, ensuring security, resilience, and long-term autonomy.

Key features and benefits

The system consists of two tokens: a governance token for a decentralized autonomous organization (DAO) and a basket token, which is fully collateralized and backed by a dynamically evolving reserve of crypto assets. The decentralized organization operates as a meritocratic, game-theoretic competition mechanism where participants propose asset allocations to optimize the reserve’s structure. While the DAO collectively sets the rules of the competition (allowed assets, staking requirements, etc.), the actual composition of the basket token is determined by combining individual participants' asset allocation proposals, with rewards distributed through stake redistribution. This system ensures that asset selection is driven by expertise and long-term performance, fostering a fair, market-driven process that prevents manipulation and encourages strategic decision-making.

The system also functions as a decentralized exchange (DEX) through its automated multi-party trade algorithm, which issues new fully collateralized tokens based on liquidity needs. This system ensures price-volume correlation while dynamically adjusting supply to maintain market balance. By integrating liquidity provision directly into its ecosystem, the protocol enhances accessibility and usability, offering a new level of efficiency in decentralized finance. Its scalable and future-ready design allows for adaptation as blockchain technology evolves, supporting sustainable economic growth while maintaining full transparency and decentralization.

DOWSERS

By applying decades of top-notch formal verification know-how to the blockchain space, Dowsers brings trust in smart contracts with a ground-breaking, scalable and accessible formal verification technology.

Bugs and vulnerabilities in smart contract code erode trust in blockchain technology, posing a significant risk to developers, investors, and financial institutions.

Dowsers is a suite of software tools and algorithms which automatically verify and formally prove the safety and providence of smart contracts before or after their deployment on a blockchain.

Formal verification is the science of proving or disproving the correctness of a system with respect to a certain formal specification or properties. It is a rigorous and mathematical method used in critical industries where human life is at stake such as nuclear plants, space rockets, airplanes, automated metros and trains. Where tests can only show the presence of a bug, formal verification proves the absence of threats by analyzing code through all possible states and conditions.

Technically, the Dowsers platform analyzes source code from repositories and/or bytecode directly on the blockchain, conducts fully automated formal static and dynamic analysis and instantly generates security reports highlighting programming errors and risks detected in the code. The Dowsers platform is designed to verify and detect threats in smart contracts whatever their language, blockchain, and code execution environment.

In detail, the Dowsers platform enables blockchain users to:

• Identify common vulnerabilities in smart contracts, including reentrancy attacks, race conditions, authorization management errors, stack and buffer overflows, and vulnerabilities related to external calls.
• Analyze smart contract logic to detect ambiguities, inconsistencies, or unexpected behaviors that attackers could exploit to compromise security.

• Verify compliance with best practices, such as minimizing permissions, securely managing sensitive data, and using reputable security libraries.

   

Dowsers addresses essential cybersecurity challenges for two key customer segments: 

• Developers: in one click, developers get a thorough report about all potential issues in their code, line by line, and can make their smart contracts bulletproof before their deployment on the blockchain.
• Investors: in one click, investors get a thorough report of all potential financial risks contained in the code of cryptocurrencies and tokens before investing into such digital assets.    

Enoda Technologies S.L

Enoda ENSEMBLE™ - Decentralized Coordination of Distributed Energy Resources

ENODA was established in 2021, and delivers leading-edge innovations in energy technology. ENODA technologies can solve the fundamental challenge of the energy system: balancing exponentially rising electricity demand using generation sources that are both volatile & variable.

The European Green Deal is changing the energy ecosystem: more renewable and distributed energy resources (DERs), like solar panels and wind turbines, are connecting to the grid. Modern loads like heat pumps and EV chargers are volatile, and cause stress on grid infrastructure. The result is that the cost and complexity of balancing the grid is rising exponentially, and the need to resolve the limitations of the legacy grid is becoming urgent.
Enoda ENSEMBLE™ is a DLT platform designed to enable DERs, including the Enoda PRIME® Exchanger, to provide frequency and ancillary services to maintain the grid frequency at 50 Hertz. Frequency stability is crucial: if the frequency drifts more than ±0.5 Hz, it can lead to system instability, equipment damage, and power outages. Frequency and ancillary services have traditionally been provided by fossil-fuelled peaker plants, but they are expensive and carbon-intensive.
Through Ensemble, energy market participants—from grid operators to small aggregators—can seamlessly coordinate DERs to provide frequency and ancillary services. The result is drastically reduced transaction costs, and reduced barriers-to-entry for renewables. Smart contracts can enable secure transactions in near real-time, which creates a dynamic balancing mechanism that is adaptable to the evolving energy ecosystem. 
Ensemble’s robust, privacy-preserving design uses private-permissioned blockchain networks and cryptographic safeguards, and meets regulatory requirements such as AML/KYC standards. Data protection and GDPR compliance are of utmost importance in the design. The decentralized approach delivers transparent performance data to regulators and stakeholders, which creates trust and fosters broader market engagement.
By lowering reliance on conventional fossil-fuelled peaker plants and improving real-time grid flexibility, Ensemble helps support the European Green Deal and the broader goal of a secure, decentralized energy ecosystem. The platform’s integration with IoT devices, AI-driven optimization, and built-in compliance is designed to set a new benchmark for sustainability and resilience in the energy sector. 
Ultimately, Ensemble paves the way for an inclusive, dynamic, more democratic, and future-proof energy system framework that bridges DLT innovation with Europe’s ambitious climate and digitalization targets.
 

Fair Squares B.V.

FAIR SQUARES: AFFORDABLE HOUSING FUNDING PROTOCOL

More than 40 million people in the EU struggle to find affordable housing. Traditional funding systems generally fail to provide enough affordable houses. That’s why we need a new way to finance, manage, and make decisions about housing. Fair Squares is designed to make housing fairer while ensuring affordability, transparency, and true ownership. Instead of relying on big corporations or only on governments to organize housing, we think that all stakeholders and users - tenants, investors, and housing organizations - should have a say in how things work.

How It Works

Our goal is to make housing affordable while offering modest and stable returns to investors.
Here’s how we do it:

• Community-powered rent control - The community decides the return on investment, which directly influences rent prices and keeps them affordable.
• Low-risk investments - Instead of buying one property, investors fund a diverse pool of properties, reducing risk and making housing more stable.
• A new way to fund housing - Fair Squares introduces a distributed digital funding model using tokenization. This means:
  • Every investor owns a small, trackable share of real housing assets.
  • Unlike traditional real estate investments, prices do not rise based on speculation. The focus stays on affordability.

What We Do

Fair Squares takes care of the financial side of housing, so that:

• Tenants have secure, affordable housing with clear rights.
• Housing organizations manage properties while ensuring responsibilities like maintenance are met.
• Investors can contribute in a fair, sustainable way and receive stable returns.

To keep it secure and transparent, we use digital identifiers which is a safe and a verifiable way to confirm who owns or rents a property.

Why This Matters

Right now, many housing systems favour profit over people. Fair Squares creates a community-driven housing model that works and ensures affordability, transparency, and stability for everyone involved.

OnePass (Accelerate, Bulgarian Industrial Association, Funding Box, The Edge, Walt.id, Veloxoft) 

Introduction and project vision

The goal of the OnePass project is to enable cross-border investment opportunities within Europe by creating a trust framework between startups, investors, and trusted operators of services to startups using verifiable credentials. The project aims to create transparency of information and procedures for investing in early-stage startups by leveraging Web3 technology through the EBSI infrastructure to create a common trust network for universal verification of both startups and investors.

 

Problem Statement

Fundraising is a big unsolved challenge for both sides of the market. On the one hand, SMEs and particularly new Startup founders, must face a high opportunity cost in discovering funding opportunities and dealing with a lot of red tape for demonstrating they are ready to be invested or to receive a public grant. On the other hand, investors and operators of innovation funding must spend more than 10% of their available funds, in dealing with Know Your Customer (KYC) and Know Your Business tasks (KYB), representing a high opportunity cost for them. Besides this, the cross-border gap for both sides of the market is even worse as the fundraising challenge requires start-ups from less connected ecosystems to move to more established hubs elsewhere in Europe to find investors. This is due to the fact that better-connected innovation ecosystems benefit from more local accelerators with greater funding opportunities and more qualified business support services compared to their counterparts elsewhere.

Solution

The project leverages the power of the European Blockchain Services Infrastructure (EBSI) to build the foundations of a new digital trust framework to facilitate cross border investment opportunities within Europe. EBSI allows this project to design, build, and operate the next generation of decentralised services for SME funding processes. 

The objective of this project is to develop and implement a dedicated trust network that connects verified startups, investors, and ecosystem enablers, streamlining fundraising, compliance, and partnership-building. By leveraging EBSI, the network benefits from its alignment with EC standards for eID, VCs, and Trust Framework Governance, as well as the potential network effects that can enhance the scalability through its ecosystem.

Key Features

• 3 different verification levels.
  • KYB (Know your business), a procedure aimed at verifying the legal existence of a company.
  • KYC (Know your customer, aimed at verifying a natural person’s identity.
  • Momentum, an indicator of a startup’s investability based on several factors, such as team, resources, technology, and traction.
• Cross-Border Investment Facilitation: A verified ecosystem that connects startups with investors and institutions across multiple jurisdictions.
• Trust-Based Interactions: utilization of verifiable credentials to ensure transparency and reliability in business engagements.
• Regulatory Compliance Support: Provides tools for startups and investors to meet cross-border regulatory requirements.
• Interoperability: Ensures seamless collaboration with other trust networks and compliance frameworks.
• Security & Privacy: Built-in cryptographic protections to safeguard sensitive business data.
  
   

Target Audience

• SMEs (Holders): (Small to medium sized enterprises, particularly early-stage startups, searching for their first investments.
• Investors (Verifiers): Private equity investors that provide capital to companies with high growth potential in exchange for an equity stake. They would like to spend less time evaluating startups and have greater access to opportunities outside their ecosystem.
• Accelerators (Issuers): Startup accelerators or seed accelerators. Could act as the issuers of either the KYB or investability credentials to startups within their ecosystems giving them greater visibility and trust with potential investors.
• EU|BICs quality-certified organisations (Issuers):  that use business and innovation as a force for regional (economic, sustainable, and social) development. Potential issuers of the KYB/Investability credentials. 

Market Opportunity

Europe's entrepreneurial landscape has experienced remarkable growth, with the number of early-stage companies increasing from approximately 7,800 in 2015 to over 35,000 by 2024^[1].
Each year, thousands of investors across Europe are looking for high-potential startups to support. The total SAM (Serviceable Available Market) is estimated to be around 1300 investors. Accelerators have become a vital part of the startup ecosystem, with over 300 accelerators across Europe supporting thousands of startups every year.

Implementation plan

The first part of the project involved the development and implementation of the governance framework, verifiable credential schemas, and technical onboarding with EBSI. 

This final phase of the project involves the issuance of verifiable credentials, gaining user feedback and the expansion of the use case.

The Renewable Energy Communities (RECs) use case demonstrates how blockchain technology can revolutionize decentralized energy management and distribution. Leveraging Distributed Ledger Technology (DLT), smart contracts, tokenization, and decentralized autonomous organizations (DAOs), RECs enable local households, businesses, and public entities to collectively own, govern, and manage energy assets. This cooperative model enhances transparency, efficiency, and community engagement while promoting sustainability and decentralized energy distribution. This initiative underscores the transformative potential of blockchain in creating resilient and transparent energy systems that align with the EU's broader climate and innovation goals.

Key components of the REC use case:

1.    Tokenization of Energy and Financial Instruments: Tokenization is a cornerstone of the REC's operations, enabling the creation of digital assets for energy tokens (offtake), control (voting), membership, ownership (shares, participations), and finance (loans and bonds). Energy Tokens quantify and share energy value among members and local consumers, while membership (shares and participations) provide ownership and governance rights.

2.    Participant Wallets: Equipping participants with digital wallets, allows them to manage and trade their tokens seamlessly. Enhancing user experience, enabling easy tracking of energy tokens, control (voting), ownership (participations, shares), and investment returns (loans and bonds). They also ensure secure storage and transfer of digital assets.

3.    Decentralized Autonomous Organization, DAO: Control (governance) within RECs is supported by a DAO setup, which facilitates democratic decision-making and community engagement. By leveraging blockchain's transparency and security, digital governance ensures that governance processes are fair, inclusive, and efficient. Members can develop and vote on proposals, allocate resources via the treasury manager function, and jointly shape the future of their own energy community.

4.    Privacy, Regulatory Compliance, and Taxation: The REC use case addresses critical questions around personal and commercial privacy, ensuring compliance with regulations such as the European Energy Directives (Fit for 55 package, Renewable Energy Directives), European taxation directives (digital platforms DAC7 and crypto assets service providers DAC8), personal privacy (GDPR), and commercial privacy (Data Governance Act DGA), Markets in Crypto-Assets Regulation (MiCAR), and Markets in Financial Instruments Directive (MiFID). 

This use case highlights the Amelander Energie Coöperatie, which aims to harness the benefits of decentralized, community-driven energy management. By adopting DAOs, the cooperative enables collective ownership and governance of shared energy systems, strengthening local resilience and sustainability. The integration of distributed ledger technology (DLT) and smart contracts brings greater transparency and operational efficiency. Additionally, tokenizing ownership and investment instruments opens the door to a broader range of investors, enhancing financial sustainability and supporting future growth.

Tree

The Tree Protocol is a decentralized and tokenized knowledge graph protocol that enables an intelligent and scalable Digital Product Passport (DPP) data infrastructure. The protocol comprises smart contracts published on a blockchain, an API interface to index data directly to different use cases, and SDK developer tools to develop DPP solutions efficiently. It enables developers to build solutions for cross-platform data sharing.

Tree leverages product data to accelerate circular economy in various value chains, such as textiles. For instance, it allows repair, resale, and recycling companies to access high-quality OEM product data to increase efficiency and provide better services to consumers.

Tree connects brands with circular economy platforms by deploying a blockchain-powered infrastructure, transforming compliance data into profit. Specifically, it provides compliance with the EU’s upcoming DPP mandate while unlocking new revenue streams through lifecycle monetization.

To further support textile brands in adopting DPP solutions, Tree offers a Shopify plugin that allows brands to onboard seamlessly onto Tree Protocol. Additionally, through its collaboration with Vaayu, Tree enables the collection and retrieval of traceability data via an API interface, ensuring compatibility with the EU’s ESPR (Ecodesign for Sustainable Products Regulation) framework. This integration helps brands comply with evolving regulations while facilitating seamless traceability and data management within the Shopify ecosystem.

Advanced AI Models for Health Data Privacy

PHASE IV AI, a Horizon Europe-funded project, aims to generate AI models for health space. The project concept is illustrated in the figure below. The consortium for this use case is led by the University of Turku. Fujitsu Technology Solutions SA N/V is the leader of the use case, with partners including Fundació Eurecat, INESC TEC – Institute for Systems and Computer Engineering, Technology and Science, the University of Vienna and VTT Technical Research Centre of Finland. 

Artificial intelligence (AI) enables data-driven innovations in health care. AI systems, which process vast amounts of data quickly and in detail, show promise both as a tool for preventive health care and clinical decision-making. However, the distributed storage and limited access to health data form a barrier to innovation, as developing trustworthy AI systems requires large datasets for training and validation. Furthermore, the availability of anonymous datasets would increase the adoption of AI-powered tools by supporting health technology assessments and education. Secure, privacy compliant data utilization is key for unlocking the full potential of AI and data analytics. In this proposal, we will advance the current state-of-the-art data synthesis methods towards a more generalized approach of synthetic data generation. We will also develop metrics for testing and validation, as well as protocols that enable synthetic data generation without access to real-world data (through multi-party computation).
