Proof of User Similarity: the Spatial Measurer of Blockchain
Shengling Wang, Lina Shi, Hongwei Shi +3
Although proof of work (PoW) consensus dominates the current blockchain-based systems mostly, it has always been criticized for the uneconomic brute-force calculation. As alternati…
Active Defense Analysis of Blockchain Forking through the Spatial-Temporal Lens
Shengling Wang, Ying Wang, Hongwei Shi +1
Forking breaches the security and performance of blockchain as it is symptomatic of distributed consensus, spurring wide interest in analyzing and resolving it. The state-of-the-ar…
Extending On-chain Trust to Off-chain -- Trustworthy Blockchain Data Collection using Trusted Execution Environment (TEE)
Chunchi Liu, Hechuan Guo, Minghui Xu +4
Blockchain creates a secure environment on top of strict cryptographic assumptions and rigorous security proofs. It permits on-chain interactions to achieve trustworthy properties…
Micro Analysis of Natural Forking in Blockchain Based on Large Deviation Theory
Hongwei Shi, Shengling Wang, Qin Hu +1
Natural forking in blockchain refers to a phenomenon that there are a set of blocks at one block height at the same time, implying that various nodes have different perspectives of…
Tokoin: A Coin-Based Accountable Access Control Scheme for Internet of Things
Chunchi Liu, Minghui Xu, Hechuan Guo +7
With the prevalence of Internet of Things (IoT) applications, IoT devices interact closely with our surrounding environments, bringing us unparalleled smartness and convenience. Ho…
Proof of Federated Learning: A Novel Energy-recycling Consensus Algorithm
Xidi Qu, Shengling Wang, Qin Hu +1
Proof of work (PoW), the most popular consensus mechanism for Blockchain, requires ridiculously large amounts of energy but without any useful outcome beyond determining accounting…
