## 5 Evaluation of Music Rights Framework  
In this section, the entire reasoning of the framework is specified and afterwards the results of a batch claim upload assessment are outlined. State-of-the-art music industry copyrights management applications and platforms approach the copyrights governance process with centralized systems that offer distributed replication database servers for fault tolerance and high availability. Thus, each stakeholder business actor utilizes their own database, whereas it is possible that a small number of distinct actors operate under the same technological components. However, the entire music industry stakeholder ecosystem (Figure 1) utterly suffers from diversity, considering the technologies applied to storing, retrieving and processing data. The dissimilar database systems endorse different ways of organizing information, i.e. data format, database type, and query syntax. In this context, data sharing between the stakeholder business actors usually constitutes a challenging procedure while it is one of the main reasons for the GRD's failure constitutes the number of different sources from which data would arrive [1]. The music rights framework resolves this diversity problem by exploiting blockchain infrastructure. The presented framework provides a single network inside which all information is securely stored and shared among the selected actors that are approved to participate. As already stated, this framework, through its dedicated smart contracts deployed in the quorum-based permissioned blockchain network, offers data transparency, traceability and decentralization along with participant trust and claim conflict resolution in an efficient system. Moreover, data immutability is guaranteed through blockchain immutable transactions, while centralized storage risks of data protection and cyber-security attacks are eliminated. It is important to clarify in the current use case that the perception that the blockchain ledger is presented as a database replacement is only valid in the context of storing relatively small amounts of data on a Solidity structure. Each claim is represented mostly by its metadata (Figure 7), using an accepted data amount to store on-chain. Blockchain is not suitable for depositing larger files, such as e.g. multimedia ones. Ultimately, the music industry ecosystem functioning under the proposed framework would provide its stakeholder business actors a privately shared and secure network inside which music copyright governance, from assessment of ownership to royalty distribution and copyright validation, would occur with ease, data availability and protection and privacy. In the rest of the section, the analysis results of a batch claim upload experiment are reported. In order to test how the system is going to react under a demanding load, batch files were created in a CSV format; the files contained a series of claims in order to be processed by the system and then to be stored on the blockchain. The batch files varied in sizes (from 100 claims to 10,000 claims) in order to examine the responsiveness of the systems for different rates of claim creation. For the evaluations two graphs are presented, the first one (Figure 11) depicts the time needed in seconds to process the different sized batch files, while the second graph (Figure 12) depicts the average time needed by the system to process a claim. Given the fact that there are limitations in the block creation containing the transactions (claims), and the claims are processed in a serial way, the time needed to process the claims is relatively good. Although the system needs roughly 10 hours to process 10,000 claims, which is not an extreme claim load in the music industry, the system enables the identification of conflicts in less than a day, which is a huge improvement given the current landscape.
