Resumo(s)

This thesis explores the scalability of blockchain technology in Peer-to-Peer (P2P) renewable energy trading. As energy systems shift toward decentralized models, blockchain’s secure and transparent nature supports direct transactions between producers and consumers. Scalability remains a key challenge as networks must manage increasing transaction volumes. This study evaluates the performance of Quorum Byzantine Fault Tolerance (QBFT) and Clique within Hyperledger Besu using Hyperledger Caliper. Results show QBFT’s superior handling of higher transaction loads with lower latency and higher throughput, highlighting its suitability for high-frequency energy trading and blockchain’s potential in decentralized energy systems.
