Taxonomy of Blockchain Technologies. Principles of Identification and Classification
This provides a structured framework for researchers and practitioners to analyze and compare blockchain systems, though it is incremental as it builds on existing classification efforts.
The paper tackled the problem of understanding and comparing diverse blockchain technologies by developing a taxonomy that breaks them down into building blocks, classifies components hierarchically, and identifies alternative layouts, resulting in a navigation tool for blockchain architectural configurations.
A comparative study across the most widely known blockchain technologies is conducted with a bottom-up approach. Blockchains are disentangled into building blocks. Each building block is then hierarchically classified in main and subcomponents. Then, alternative layouts for the subcomponents are identified and compared between them. Finally, a taxonomy tree summarises the study and provides a navigation tool across different blockchain architectural configurations.
