GriDB: Scaling Blockchain Database via Sharding and Off-Chain Cross-Shard Mechanism
Zicong Hong, Song Guo, Enyuan Zhou +3
Blockchain databases have attracted widespread attention but suffer from poor scalability due to underlying non-scalable blockchains. While blockchain sharding is necessary for a s…
A Novel Two-Layer DAG-based Reactive Protocol for IoT Data Reliability in Metaverse
Changlin Yang, Ying Liu, Kwan-Wu Chin +3
Many applications, e.g., digital twins, rely on sensing data from Internet of Things (IoT) networks, which is used to infer event(s) and initiate actions to affect an environment.…
Diffusion-based Reinforcement Learning for Edge-enabled AI-Generated Content Services
Hongyang Du, Zonghang Li, Dusit Niyato +4
As Metaverse emerges as the next-generation Internet paradigm, the ability to efficiently generate content is paramount. AIGenerated Content (AIGC) emerges as a key solution, yet t…
Consensusless Blockchain: A Promising High-Performance Blockchain without Consensus
Qing Wang, Jian Zheng, Huawei Huang +1
Consensus is unnecessary when the truth is available. In this paper, we present a new perspective of rebuilding the blockchain without consensus. When the consensus phase is elimin…
