Evil Chaincode: APT Attacks Based on Smart Contract

Communications in Computer and Information Science, 2020
In this paper, we discuss methods of stealing data via advanced persistent threat (APT) attacks on blockchains. Blockchain technology is generally used for storing data and digital coins and counts more than 562 organizations among its users. Smart contracts, as a key part of blockchain technology, are used for blockchain programmability.

Similarity measure of human body movement through 3D chaincode

2017 18th IEEE/ACIS International Conference on Software Engineering, Artificial Intelligence, Networking and Parallel/Distributed Computing (SNPD), 2017
This paper proposes a method for measuring human body movement similarity by considering human body motion as a set of 3-dimensional curves representing the changes of direction. This analysis method is used for obtaining similarity values of the body movement of various subjects.

Electricity Trading Model Based on Chaincode and Multi-stage Hybrid Auction

2020 International Conference on Computer Network, Electronic and Automation (ICCNEA), 2020
As a relatively independent power grid structure, microgrid is the main application scenario for distributed energy to participate in the market transaction. The increase of its distributed renewable energy penetration leads to the decentralization of power supply.

State synchronization in process-oriented chaincode

Frontiers of Computer Science, 2019
Business processes often involve operational processes, contracts, and regulations. The modeling of such processes must address regulation monitoring and enforcement and maintain a reliable history of data for evidence. This study proposes modeling business processes as chaincode (CC) on permissioned blockchains (BCs). The challenges encountered by the

A Study On Performance Improvement Of Hyperledger Fabric Through Batched Chaincode Message

2020 21st Asia-Pacific Network Operations and Management Symposium (APNOMS), 2020
This paper is to improve the performance of Hy-perledger Fabric that is one of the private blockchain open-source projects. The decentralization of data management, which has recently become important, is realized as a blockchain. Blockchain is a technology used in various fields such as data verification, storage, and banking, but performance is one ...
