B. Introduction to blockEmulator

  • Initiated by HuangLab (a research group in the School of Software Engineering, Sun Yat-sen University, China), *BlockEmulator is a blockchain testbed that enables researchers to verify their proposed new protocols and mechanisms. It supports multiple consensus protocols, particularly the cross-shard mechanism.
  • The main purpose of this testbed is to help users (researchers, students, etc.) quickly verify their own blockchain consensus protocols and blockchain-sharding mechanisms. BlockEmulator is designed as an experimental platform that adopts a lightweight system architecture.
  • It simplifies the implementation of industrial-class blockchains since BlockEmulator only implements the core functions of a blockchain, including the transaction pool, block packaging, consensus protocols, and on-chain transaction storage. It also supports common consensus protocols, such as Practical Byzantine Fault Tolerance (PBFT) and Proof of Work (PoW).
  • In particular, BlockEmulator offers the system-level design and implementation for blockchain sharding mechanisms. For example, the cross-shard transaction mechanisms implemented by BlockEmulator include the following two representative solutions, i.e., i) Relay transaction mechanism proposed by Monoxide (NSDI’2019), and the BrokerChain protocol proposed by BrokerChain (INFOCOM’2022).
  • BlockEmulator is oriented toward blockchain researchers because it provides a blockchain experimental platform for quickly implementing their own algorithms, protocols, and mechanisms. It also offers very helpful functions for researchers to help them collect experimental data, facilitating their experimental charts.

#1. Dataset & Codes for Predicting Machine Failures

Background: This dataset is to implement the failure prediction using machine learning methods and AI approaches such as SVM, random forest, or deep learning algorithms. Besides the original dataset, I also provide two reports written by two visiting students when they performed a visiting-study in my lab in July 2019.
