The hardest part of building a new commodity market isn't the technology. It's convincing the first farmer to trust a digital ledger over a handshake. CofiBlocks, a small startup in Alajuela, Costa Rica, is trying to do exactly that, using a blockchain-based social currency to rewrite the rules of a local coffee trade that has operated the same way for generations.
Founded in 2022, the company is building a collaborative marketplace on the Starknet blockchain. Its model aims to connect small coffee producers directly with roasters, designers, and consumers. The twist is a token called COFI, which represents a share in the collective business and is used to distribute profits and voting rights [CofiBlocks]. It's an ambitious attempt to apply regenerative finance, or ReFi, principles to a physical, deeply traditional supply chain.
A bet on collaborative ownership
CofiBlocks describes itself as the first collaborative business of Costa Rica's traditional coffee community [CofiBlocks]. The concept is a direct response to the volatility and opacity small farmers face. Earlier coverage characterized the project as a monthly fair-trade subscription that pays producers in advance, helping them plan and forecast revenue [TechRound, February 2024]. The blockchain layer adds a mechanism for shared governance and value distribution beyond a simple advance payment.
Members who join the pilot can claim COFI tokens through an associated app built by Cambiatus, a blockchain platform for community currencies [CofiBlocks][Cambiatus]. These tokens are not a speculative cryptocurrency but a "social currency" tied to participation. The idea is that as the marketplace grows and generates revenue, value flows back to token holders, which includes the farmers themselves. This creates a financial incentive for community participation that aligns with the cooperative's long-term health.
The team building a digital beneficio
The founding team blends deep local roots with blockchain expertise. Co-founder Omar Hurtado Munguía progressed from coffee picker to tour guide in the Poás region, providing firsthand insight into producer challenges [CofiBlocks]. His co-founders, Karla Córdoba Brenes and Ranulfo Paiva Sobrinho, bring experience in blockchain-based impact solutions. Córdoba Brenes is also the President of the Blockchain Association of Costa Rica, and Paiva Sobrinho is a co-founder of Cambiatus, the platform underpinning CofiBlocks' token system [CofiBlocks][LinkedIn].
This combination is critical. The technical challenge of deploying a marketplace on Starknet is one thing. The social challenge of onboarding a community skeptical of digital abstractions is another. Having founders who can speak both languages, from the farm to the smart contract, may be the project's most valuable asset.
Early traction and grant support
Evidence of live operation is still early and geographically contained. The company's app is described as experimental and available only in Costa Rica [CofiBlocks]. One coffee producer, Beneficio Las Peñas, has been identified as an onboarded member, participating in tasting events for the project [A Regenerative Brunch to Seed the Future of Blockchain, Unknown].
External validation has come through non-dilutive grants, a common path for mission-driven web3 projects. In August 2024, CofiBlocks announced it had received a grant from the Starknet Foundation to develop its marketplace on that network [CofiBlocks LinkedIn, August 2024]. A separate listing indicates a $25,000 grant from the same source [Starknet Seed Grants, Unknown]. The project also won Welthungerhilfe's global InnoJourneys Challenge in December 2025 for its "Digital Coffee Governance & Market Access" concept [Welthungerhilfe, December 2025].
The company's structure and scale remain small, with public data suggesting a team of between one and ten people [LinkedIn][RocketReach].

The technical breakdown: COFI on Cambiatus
To understand the bet, you have to look at the stack. CofiBlocks is not building a blockchain from scratch. It's deploying on Starknet, a layer-2 network for Ethereum, which provides scalability for transactions. The social currency, COFI, and the governance mechanics are built using Cambiatus, an open-source platform designed specifically for community currencies and collaborative organizations [Cambiatus].
This is a pragmatic choice. Cambiatus handles the issuance, distribution, and voting mechanics for tokens like COFI. It means CofiBlocks can focus on community onboarding and marketplace economics rather than core protocol development. The tradeoff is dependency on the Cambiatus platform's roadmap and the ongoing performance of the Starknet network. For a small team, it's the right tradeoff, but it introduces a layer of architectural risk.
Where the model faces friction
The vision is compelling, but the path to scale is lined with very real obstacles. The primary risk is adoption velocity within the target community. Smallholder farmers are not a typical early-adopter demographic for blockchain products. The utility of a COFI token must be immediately and tangibly better than the existing, familiar system of cash payments and local cooperatives.
- Community trust. The model only works if a critical mass of producers and buyers opt in. This requires sustained, in-person community organizing, which is resource-intensive and slow.
- Regulatory clarity. While social currencies for specific communities may operate in a gray area, scaling any token-based revenue distribution invites regulatory scrutiny, especially if perceived value increases.
- Market competition. The value proposition is against an entrenched, low-tech status quo, not other blockchain startups. The competitor is inertia.
The company's answer to these challenges appears to be a focus on deep local integration and education, leveraging the founders' community standing. The grant from the Starknet Foundation provides runway to prove the model with a small group before attempting wider expansion.
The next twelve months
The immediate milestone is demonstrating a working loop. That means showing that coffee can be sold through the marketplace, that revenue is generated, and that COFI token holders receive a distribution. Success is a handful of producers reliably receiving more value through the CofiBlocks system than they would outside it. The team will also need to expand beyond the single confirmed producer, Beneficio Las Peñas, to build a viable network.
Financially, the project currently runs on grant capital. The next logical step would be a priced equity round to fund growth, but that would require showing investor-grade metrics from the pilot. Alternatively, it could pursue more mission-aligned grant funding from impact or web3-focused organizations. The winner of the Welthungerhilfe challenge suggests this path remains open [Welthungerhilfe, December 2025].
At scale, the problems become architectural. Can the Cambiatus and Starknet stack handle thousands of transactions from a global marketplace? How does the governance model avoid capture or deadlock as the community grows? These are good problems to have, but they are not trivial. For now, CofiBlocks is focused on a more fundamental proof: that a blockchain can brew a fairer cup of coffee, one farm at a time.
