The "Rooftop that feeds" Project Using Stellar and Soroban Technology

Our project, "Rooftop that feeds," aims to transform underprivileged neighborhoods by addressing three key challenges: boosting local commerce, implementing renewable energy solutions, and combating malnutrition. The project leverages Stellar blockchain technology for creating a digital community currency and Soroban smart contracts for managing energy transactions. Here’s how it works:

1. Solar Panel Installation and Energy Generation: Homeowners Associations (HOAs) in these neighborhoods install solar panels on their rooftops. These panels generate renewable solar energy, contributing to environmental sustainability and providing a new source of income for the residents.

2. Creation of Digital Community Currency on Stellar: We use the Stellar network to issue a custom digital currency, tailored for our ecosystem. This currency facilitates transactions within the community, offering an alternative to traditional fiat money. Its creation and circulation are managed on the Stellar blockchain, ensuring transparency, security, and efficiency.

3. Energy Transaction Management with Soroban Smart Contracts: To convert the generated solar energy into a valuable commodity, we employ Soroban smart contracts. These contracts are programmed to:

   • Automatically convert the electricity produced (in kWh) into digital tokens at a predefined rate.
   • Manage transactions between the HOAs and local fresh food shops, where these shops purchase solar energy using the digital tokens instead of fiat currency.

4. Incentive Structure for HOA Members: The members of HOAs are incentivized to participate through a favorable energy-to-token conversion rate. For example, whereas the grid might compensate at 0.04 euros per kWh, our system values the same at 0.20 euros per kWh in community currency. This higher rate, made possible through our agreements with local businesses, motivates HOA members to accept the community currency in exchange for their solar energy.

5. Circular Economy and Local Commerce Stimulation: The digital tokens received by HOA members can be spent exclusively at the participating local fresh food shops. This creates a circular economy: solar energy produced by the community is used to power local businesses, which in return support the community by accepting the digital currency.

6. Technical Advantages: The use of Stellar's blockchain ensures that the community currency is not only environmentally friendly but also benefits from low transaction costs and fast settlement times. Soroban's smart contracts add a layer of automation and precision in managing the energy-to-token and token-to-energy conversions, ensuring a seamless and fair exchange process.

A "Sociedad de Bien e Interés Común" (SBIC) in Spain is a business entity designed to align commercial interests with social and environmental objectives. While it shares similarities with Benefit Corporations (B Corps) in the United States and "Sociedades de Beneficio e Interés Colectivo" (BIC) in some Latin American countries, the SBIC has specific characteristics tailored to the Spanish legal and business environment. Key features of an SBIC in Spain include: Dual Purpose: SBICs are committed to generating a positive social or environmental impact alongside a financial return. They incorporate these dual objectives into their corporate mission. Transparency and Accountability: SBICs are required to maintain high levels of transparency. They must regularly report on their social and environmental performance, in addition to their financial performance. Stakeholder Engagement: These entities consider the interests of a wide range of stakeholders, including employees, customers, suppliers, the community, and the environment, in their decision-making processes. Legal Framework: SBICs operate under a specific legal framework that supports their unique mission. This framework provides guidelines for balancing profit-making with social and environmental responsibilities. Certification and Compliance: While the specifics can vary, SBICs typically undergo a certification process.
