The Blockchain as a Software Connector
Xiwei Xu,Cesare Pautasso,Liming Zhu,Vincent Gramoli,Alexander Ponomarev,An Binh Tran,Shiping Chen +6 more
- 05 Apr 2016
TL;DR: This paper provides rationales to support the architectural decision on whether to employ a decentralized blockchain as opposed to other software solutions, like traditional shared data storage and explores specific implications of using the blockchain as a software connector including design trade-offs regarding quality attributes.
Adaptable Blockchain-Based Systems: A Case Study for Product Traceability
Qinghua Lu,Xiwei Xu +1 more
TL;DR: The OriginChain project as mentioned in this paper is a real-world traceability system using a blockchain, which provides transparent tamper-proof traceability information, automates regulatory compliance checking, and enables system adaptability.
