    abstract = {Nowdays, modern applications often use blockchains as a secure data store.
      However, querying blockchain data is more challenging than querying
      conventional databases due to blockchains being primarily designed for the
      logging of asset transfers, such as cryptocurrencies, rather than storing and
      reading generic data. To improve the experience of querying blockchain data and
      make it comparable to querying conventional databases, new design approaches of
      the storage engine for blockchain technology are required. An important aspect
      is the data layout of a block, as it plays a crucial role in facilitating
      reading of blockchain data. In this paper, we identify a suitable data layout
      that provides the required query capabilities while preserving the key
      properties of blockchain technology. Our goal is to overcome the limitations of
      current data access models in blockchains, such as the reliance on auxiliary
      data storages and error-prone smart contracts. To this end, we compare four
      promising data layouts with data models derived from document, row, column, and
      triple stores in terms of schema flexibility, read pattern generality, and
      relational algebra suitability. We then assess the most suitable data layout
      for blockchain technology.},
