“…Instead of proposing consensus mechanism, some works specified more details and designed comprehensive blockchain systems for IoT applications, such as AEChain [107] , BPAF [108] , BET [109] , and B-MET [110] . AEChain [107] divides IoT devices into groups and assigns a blockchain node for each group as a worker to communicate with IoT devices as well as maintaining blockchain.…”

Blockchain is an emerging decentralized data collection, sharing, and storage technology, which have provided abundant transparent, secure, tamper-proof, secure, and robust ledger services for various realworld use cases. Recent years have witnessed notable developments of blockchain technology itself as well as blockchain-enabled applications. Most existing surveys limit the scopes on several particular issues of blockchain or applications, which are hard to depict the general picture of current giant blockchain ecosystem.In this paper, we investigate recent advances of both blockchain technology and its most active research topics in real-world applications. We first review the recent developments of consensus and storage mechanisms and communication schema in general blockchain systems. Then extensive literature review is conducted on blockchain-enabled Internet of Things (IoT), edge computing, federated learning, and several emerging applications including healthcare, COVID-19 pandemic, online social network, and supply chain, where detailed specific research topics are discussed in each. Finally, we discuss the future directions, challenges, and opportunities in both academia and industry.

MECAT: Memory-Safe Smart Contracts in ARM TrustZone

A smart contract is a program executed on a blockchain. However, once the smart contract is deployed on the blockchain, it becomes visible to all participants and remains immutable. Thus, any sensitive information or vulnerabilities in smart contracts can be exposed to potential attackers. To protect the confidentiality of smart contracts, existing studies execute smart contracts in a trusted execution environment (TEE). However, they still suffer from vulnerabilities in smart contracts and potential memory-vulnerability problems. If an attack such as privilege escalation occurs by exploiting this vulnerability, the TEE can have a detrimental effect on the entire system as it has the most privileges in the system. To mitigate the memory vulnerability of the smart contracts in TEE, we propose MECAT, a prototype for memory-safe confidential smart contracts. In essence, MECAT runs smart contracts written in Rust, a memory-safe language, in ARM TrustZone. And MECAT is developed as a software library, allowing developers to easily apply MECAT to their smart contracts. According to our evaluation, MECAT only incurs a 1.36x performance overhead and 0.3% power overhead in single-node environments and can process the 16 clients concurrently in the network made with 8 peer nodes.
