Abstract
In this thesis, our primary objective is to demonstrate how blockchain technology can eliminate the
need for intermediaries in energy trading, particularly in the renewable energy sector. Many
countries, despite having the potential to produce large amounts of green energy, offer limited
opportunities for businesses to directly benefit from this production. The current system often involves
multiple layers of intermediaries, which not only add to transaction costs but also create delays and
inefficiencies in the market. By leveraging the principles of decentralization and automation,
blockchain enables more direct, secure, and transparent transactions between energy producers and
buyers. Our platform seeks to simplify the trading process by allowing these parties to engage in
Virtual Power Purchase Agreements (VPPAs) without the need for intermediaries, thus reducing
costs and speeding up the transaction lifecycle. This is especially relevant for smaller energy buyers
and sellers who have traditionally been excluded from such markets due to high transaction fees and
complex contract structures.
Moreover, we selected the Layer 2 Optimistic Ethereum blockchain as the foundational network for
our project. This decision was driven by its scalability, security, and significantly lower transaction
fees compared to traditional blockchain networks. Layer 2 solutions like Optimistic Ethereum allow
us to handle a high volume of transactions while maintaining cost-efficiency, which is crucial for
enabling smaller market participants to engage in energy trading. By doing so, we also ensure that
our platform is accessible to a wider range of users, contributing to the democratization of energy
markets, disrupting the traditional energy trading landscape, fostering a more open, decentralized,
and cost-efficient environment for renewable energy transactions, while also paving the way for more
businesses to participate in the green energy transition.
