Abstract
Public blockchain networks such as Ethereum are typically not suitable for enterprise use cases due to varying reasons such as their low throughput, fees, inefficient consensus protocols and inability to store sensitive data confidentially. Permissioned blockchain frameworks allow enterprises to set up a private network to enable trustless collaborations securely. Hyperledger Fabric and Hyperledger Besu are two such frameworks. The aim of this thesis is to provide an in-depth comparison of both frameworks. More specifically, this study looked at their architectures and architectural components, their transaction flows from transaction creation until commit, how both frameworks reach agreement on ledger state using consensus protocols, how each framework aims to achieve data privacy within the network, and how each framework performs in practice for various configurations. For the first four perspectives, both frameworks are first analyzed separately, after which their differences are discussed side-by-side. Our findings are both of a higher level of abstraction, as well as a more fine-grained technical level. For both frameworks, a number of ideas for future research are provided that could potentially enhance both frameworks.
