AlphaBlock: An Evaluation Framework for Blockchain Consensus Protocols
Haitao Xiang, Zhijie Ren, Ziheng Zhou +2
Consensus protocols play a pivotal role to balance security and efficiency in blockchain systems. In this paper, we propose an evaluation framework for blockchain consensus protoco…
SURFACE: A Practical Blockchain Consensus Algorithm for Real-World Networks
Zhijie Ren, Ziheng Zhou
SURFACE, standing for Secure, Use-case adaptive, and Relatively Fork-free Approach of Chain Extension, is a consensus algorithm that is designed for real-world networks and enjoys…
VAPOR: a Value-Centric Blockchain that is Scale-out, Decentralized, and Flexible by Design
Zhijie Ren, Zekeriya Erkin
Blockchains is a special type of distributed systems that operates in unsafe networks. In most blockchains, all nodes should reach consensus on all state transitions with Byzantine…
A Scale-out Blockchain for Value Transfer with Spontaneous Sharding
Zhijie Ren, Kelong Cong, Taico V. Aerts +3
Bitcoin, as well as many of its successors, require the whole transaction record to be reliably acquired by all nodes to prevent double-spending. Recently, many blockchains have be…
Transaction Propagation on Permissionless Blockchains: Incentive and Routing Mechanisms
Oguzhan Ersoy, Zhijie Ren, Zekeriya Erkin +1
Existing permissionless blockchain solutions rely on peer-to-peer propagation mechanisms, where nodes in a network transfer transaction they received to their neighbors. Unfortunat…
Implicit Consensus: Blockchain with Unbounded Throughput
Zhijie Ren, Kelong Cong, Johan Pouwelse +1
Recently, the blockchain technique was put in the spotlight as it introduced a systematic approach for multiple parties to reach consensus without needing trust. However, the appli…
Secure Transmission on the Two-hop Relay Channel with Scaled Compute-and-Forward
Zhijie Ren, Jasper Goseling, Jos H. Weber +1
In this paper, we consider communication on a two-hop channel, in which a source wants to send information reliably and securely to the destination via a relay. We consider both th…
