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 and 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 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 plotting experimental figures.
