Building Redactable Consortium Blockchain for Industrial Internet-of-Things

IEEE Transactions on Industrial Informatics, 2019
Applying consortium blockchain as a trust layer for heterogeneous industrial Internet-of-Things devices is cost-effective. However, with an increase in computing power, some powerful attacks (e.g., the 51% attack) are inevitable and will cause severe consequences.

Techruption Consortium Blockchain – what it takes to run a blockchain together

, 2018
This paper presents initial results of the Techruption Consortium Blockchain experiment. The purpose of the experiment is to learn what it takes to run a permissioned consortium blockchain infrastructure together, not only from a technical perspective, but also governance and business model. The experiment turned out to be surprisingly complex, running

A Certificateless Consortium Blockchain for IoTs

2020 IEEE 40th International Conference on Distributed Computing Systems (ICDCS), 2020
Blockchain is multi-centralized, immutable and traceable, thus is very suitable for distributed storage, privacy and security management in IoTs. However, most existing researches focus on the integration of public blockchain and IoTs. In fact, problems such as slow consensus, low transmission throughput, and completely open storage on the public ...
