IN SAFE HANDS 53 Public, distributed, decentralisedBy definition, a blockchain is a distributed ledger %u2013 a database that is shared across a network of computers instead of being stored on a central server. Decentralisation is at the core of this concept. Rather than one big company holding all the sensitive information, the data are spread across the whole network. No one has total control. Instead, all users have collective control. Before a transaction is recorded on the ledger, it must be validated by everyone in the network, and the record cannot be altered retroactively. This Prof. Daniel Xiapu LUOProfessor, Department of ComputingDirector, Research Centre for Blockchain TechnologyProf. Luo specialises in the security of blockchain and smart contracts, mobile and IoT, software and systems, and networks. His research has earned him 16 best/distinguished paper awards, such as ACM CCS 2024 Distinguished Paper Award, four ACM SIGSOFT Distinguished Paper Awards, Best DeFi Papers Award 2023, Best Paper Award at INFOCOM 2018, etc. He also received the BOCHK Science and Technology Innovation Prize (FinTech). His research has revealed critical vulnerabilities in blockchain, mobile apps, IoT devices, and vehicles, and has been used by industry to detect and analyse malware and cyberattacks.Prof. Allen Man-ho AU Professor and Associate Head (Research and Development), Department of ComputingProf. Au obtained his bachelor%u2019s and master%u2019s degrees from the Chinese University of Hong Kong and his PhD from the University of Wollongong, Australia. Previously, he held a faculty position at The University of Hong Kong. His major research areas are cybersecurity, blockchain, and applied cryptography. Prof. Au has twice won the ZPrize, received the PET RunnerUp Award for privacy research, and was honoured with the 2023 BOCHK Science and Technology Innovation Prize in FinTech.
