Configuring blockchain architectures for transaction information in blockchain consortiums: The case of accounting and supply chain systems
TLDR
This paper investigates alternative configurations of different blockchain architectures that can be used for gathering and processing transactions in a range of different settings, including accounting, auditing, supply chain and other types of transaction information.Abstract:
This paper investigates alternative configurations of different blockchain architectures that can be used for gathering and processing transactions in a range of different settings, including accounting, auditing, supply chain and other types of transaction information. Although there has been substantial focus on the peer‐to‐peer and public versions of blockchain, this paper focuses primarily on cloud‐based and private configuration versions of blockchains and investigates use configurations, advantages and limitations as firms bring blockchain‐based market mechanisms into their organizations. In addition, this paper investigates some emerging issues associated with blockchain use in consortium settings. Finally, this paper relates some proposed uses of blockchain for transaction processing to other technologies, such as data warehouses and databases.read more

Towards an Ontology-Driven Blockchain Design for Supply Chain Provenance
TL;DR: A case for why ontologies can contribute to blockchain design is made and a traceability ontology is analyzed and some of its representations are translated to smart contracts that execute a provenance trace and enforce traceability constraints on the Ethereum blockchain platform.
