A comprehensive empirical study is performed to measure the performance
of a Blockchain-based Certi cation Storage System in Hyperledger Fabric.
This work is based on a proof of concept in the aviation industry and fol-
lows a Technical Risk & E cacy evaluation strategy to determine the utility
derived from the use of the artefact. Relevant tuning parameters for per-
formance and scalability as well as bottlenecks are identi ed. The impact
of con guration parameters such as blocksize, transaction arrival rate and
number of concurrent users on the systems performance is investigated. Ob-
servations show that demands at throughput above system limits lead to
transaction failures. Contributed are a repeatable process to performance
sensitivity analysis and recommendations for con guring a Blockchain-based
Certi cation Storage System for stable but high performance. The results
can be used as a basis for optimizing the performance of similar systems.
