Teodor Petricevic (X: @XtXeXo) leads blockchain initiatives at the UN Development Programme. He will map Ethereum-based projects within the UN ecosystem and develop an impact management framework that enables global development organisations - such as UN agencies - to effectively design impact models, measure and analyse outcomes and impacts, and harness the unique properties of blockchain technology to advance global development initiatives.
Over the past six months, I've had the privilege of leading a project that sits at the intersection of two worlds that have animated my work for decades: trust‑building in crisis and technology as a tool for making sustainable impact. From organising anarcho‑punk collectives in wartime Croatia – where we had to create solidarity amid chaos with nothing but conviction and improvisation – to leading blockchain initiatives across UNDP's Alternative Finance Lab(opens in a new tab), I've always believed the same principle: when communities have agency and can verify outcomes together, systems become more resilient and fair.
This project, born from the Ethereum Foundation's Next Billion Fellowship, has crystallised that belief into a practical, scalable framework. We set out to answer a simple but urgent question: How can we bridge Ethereum innovation with the UN's development mandate, moving beyond limited pilots toward verifiable, scalable impact?
I'll be honest—the journey to this moment was anything but linear (as life generally isn't). In the 1990s, as bombs fell across Croatia and in the post-war period, I was part of small circles of people trying to create spaces of resistance and care through music, DIY culture, and radical solidarity. We had no budget, no formal structure, just deep mutual trust and a shared conviction that another way was possible. Over 25 years, I channeled that ethic into social entrepreneurship and impact work across Europe and the Middle East - launching innovative capacity-building programs, impact acceleration programs, alternative finance mechanisms, designing impact measurement systems, building coalitions between governments, civil society organisations, communities, and funders and investors. The thread running through it all was the same: How do we create systems where trust is distributed, not concentrated? Where communities see the results of their engagement? Where power isn't hidden in black boxes?
When I joined UNDP's AltFinLab, I began exploring blockchain not as hype, but as a trust technology - a way to anchor coordination and transparency in systems where institutional actors have conflicting incentives. Over the past three decades, I learned that sustainable impact requires both conviction and credibility. And credibility, in the development world, means evidence: comparable data, auditable outcomes, and frameworks that both builders and institutions can trust.
This six-month Next Billion Fellowship was the opportunity to formalise that insight. We set out to map Ethereum-based projects across the UN ecosystem and develop a practical impact framework to bridge blockchain innovation with institutional development needs - not as another experiment, but as a foundation for scaling verified, replicable solutions.
The Next Billion Fellowship resonated deeply because it articulated something I'd been grappling with for years: Ethereum as infrastructure for trust, coordination, and empowerment - especially for the next billion users, many of whom are in developing contexts where institutional trust is fragile or absent. The Fellowship's framing was clear: Ethereum's core affordances - decentralisation, transparency, composability - could unlock new pathways for financial inclusion, digital identity, and governance.
But here's the harder truth we confronted early on: the UN-Web3 space is graveyard-adjacent. Over the past decade, countless blockchain pilots within UN agencies have stalled, scaled minimally, or been quietly archived. The crisis is real and multifaceted:
The core crisis, distilled, was misalignment and mistrust. Builders were building; UN agencies were evaluating - but they were speaking past each other. An impact framework wasn't luxury; it was essential. Not another framework that tells people what to measure, but one that bridges both ecosystems - helping Ethereum projects design for institutional credibility, and helping UN agencies understand when and how blockchain adds real value.
The fellowship unfolded in four distinct phases, each with concrete outputs designed to progressively build evidence and credibility.
We started where most projects should: understanding the landscape. Desktop research, structured interviews, and validation with UN Digital Solutions Center, UN Innovation Network databases, and Ethereum Foundation directories gave us a comprehensive view. The output: a curated dataset of 51 verified Ethereum and EVM-compatible projects across the UN system(opens in a new tab), broken down by blockchain domains (financial inclusion, governance, supply chain, digital identity, and climate action).
Permissioned and hybrid blockchains dominated - because data protection and regulatory compliance matter more than decentralised hype. Public-private partnerships were the modal governance form (>90% of initiatives). Africa led geographic distribution (47.6% of projects), but coverage gaps existed in Central Asia. Crucially, impact measurement was inconsistent: while 60%+ tracked KPIs, methodologies were idiosyncratic and rarely made clear connections and contributions to specific SDG indicators.
Key deliverable: a detailed mapping database with sectoral breakdowns and 11 use cases shortlisted for deeper analysis. This wasn't a list - it was a knowledge commons, designed for replication and comparative analysis.
We selected 11 high-priority projects and assessed them rigorously using weighted scoring across feasibility, viability, and desirability, with explicit risk ratings for legal, technical, and adoption barriers. The assessment was not academic - it directly informed which projects we'd develop into compelling impact stories.
We then worked with five standout projects to craft narratives that bridged both worlds:
Each impact story went beyond outputs - it captured causality, beneficiary agency, and institutional learning. We used mixed methods: interviews, on-chain data, independent evaluations, qualitative feedback, and honest reflection on what blockchain added versus what it didn't.
This was the intellectual heart of the work. We audited existing UN frameworks - UNDP's SDG Impact Standards, UN Impact Measurement & Management (IMM), Result-Based Management (RBM) - and synthesised them with emerging Web3-native approaches (quadratic funding, impact tokens, hypercerts, retroactive public goods funding, etc.). The final result: the Ethereum × UN Impact Framework, structured based on multiple complementary documents:
Two key documents then pulled all the strands together into a concrete, reusable architecture:
We tested the framework through intensive consultations - 11 Ethereum organisations/initiatives and 5 UN and impact management experts reviewed iterations, offering feedback that fundamentally shaped the final version.
A framework is elegant on paper; usability in the field is another matter. We developed the Ethereum × UN Impact Guideline(opens in a new tab) - a practical, actionable toolkit with:
Key deliverable - comprehensive implementation guideline, designed for practitioners, project teams, and institutional partners, accompanied with a one-pager impact guideline overview.
All outputs are open-source and accessible - the mapping table is a living .csv file, the framework documents are published, and the toolkit is designed for forking and adaptation. We believe in transparency and composability, not lock-in.
Walking through this work, several insights emerged - some confirming years of intuition, others surprising.
Five major use cases we documented - financial inclusion (Bloinx, Rahat), supply chain transparency (Blue Circle), digital credentials (ITCILO), humanitarian coordination (Building Blocks) - contribute directly to SDGs 1 (No Poverty), 2 (Zero Hunger), 5 (Gender Equality), 8 (Decent Work and Economic Growth), 12 (Responsible Consumption and Production), 13 (Climate Action), and 16 (Peace, Justice and Strong Institutions). The problem wasn't a lack of solutions; it was a lack of comparable language. Ethereum builders spoke of gas fees and transaction throughput; UN agencies spoke of cost per transaction and beneficiary reach. The framework translates between them.
For UN agencies: The framework provides a decision tree for when blockchain is justified versus when alternatives suffice. It surfaces governance and incentive risks early. It anchors blockchain projects within SDG targets, not as isolated pilots.
For Ethereum builders: The framework legitimises their work. It shows how to structure impact measurement and management from day one, not as an afterthought. It maps their solutions to institutional needs, and offers a pathway to institutional partnerships.
For communities and beneficiaries: Perhaps most importantly, the framework insists on community-led governance, not captured governance. It mandates veto power over metrics and funding influence, ensuring that those most affected shape evaluation.
This became the ethical spine of our work. In pilot after pilot - Bloinx in Burundi, Rahat in Nepal, Blue Circle in coastal China - the deepest impact came when communities weren't just beneficiaries, but co-governors. They shaped interface design, set the pace of rollout, and offered course corrections. Metrics and funding shouldn't be imposed by external evaluators; they should be negotiated, with communities holding veto power.
Honest work requires honesty about uncertainties. Here are the key tests ahead:
Our framework proposes triple-proof verification: on-chain evidence (transactions, attestations) triangulated with qualitative evidence (interviews, focus groups) and administrative data (program logs, surveys). In theory, this should converge on reliable impact signals. In practice, does it?
Test: pilots in 3–5 agencies across different sectors (humanitarian, financial inclusion, supply chain). Target: 90% convergence across the three proof types within 12 months.
Community-led governance sounds beautiful; practically, it's vulnerable. Capture can happen subtly: when crypto-native participants dominate forums, when token incentives privilege the wealthy, when metrics favour what's easy to measure over what matters.
Safeguard: annual audits of governance participation, with explicit targets for inclusion of non-crypto participants. Fallback: kill-switch if capture indicators cross thresholds.
Some contexts (like Nepal in Rahat's case) restrict public blockchains; permissioned alternatives work but reduce some affordances. Others may prohibit specific features (digital identity on-chain, token incentives, etc.).
Test: pilots in jurisdictions with varying regulatory postures. Fallback: maintain design flexibility so the framework adapts to permissioned blockchains, hybrid approaches, and even non-blockchain digital alternatives when regulation mandates.
We've done the hard intellectual work. But institutionalising it - making it native to UN procurement, Ethereum ecosystem funding, Ethereum product development, academic evaluation - requires buy-in we haven't fully secured yet.
Action: v1.0 will prioritise adoption pathways with specific agencies and Ethereum organisations.
Explicit kill-switches: If we hit 3 major failures (pilot abandonments, metric gaming, governance capture without remedy), we pause and redesign rather than scale.
This six-month journey has accelerated a longer arc I've been on for years: toward deeper integration between Web3 and Ethereum's innovation and the UN's development mandate, grounded in evidence, community agency, and humility about what technology can and cannot do.
The framework is ready. The stories are told. The toolkit is built. But this is v0.1, and it exists to be tested, critiqued, and remixed by the community it serves.
This is an invitation, not a conclusion. We're building v1.0 of the framework, and we need you:
