Greedy-Mine: A Profitable Mining Attack Strategy in Bitcoin-NG
Junjie Hu, Zhe Jiang, Chunxiang Xu
Bitcoin-NG is an extensible blockchain protocol based on the same trust model as Bitcoin. It divides each epoch into one Key-Block and multiple Micro-Blocks, effectively improving…
Novel bribery mining attacks in the bitcoin system and the bribery miner's dilemma
Junjie Hu, Chunxiang Xu, Zhe Jiang +1
Mining attacks allow adversaries to obtain a disproportionate share of the mining reward by deviating from the honest mining strategy in the Bitcoin system. Among them, the most we…
On k-error linear complexity of binary sequences derived from Euler quotients modulo 2p
Chenhuang Wu, Vladimir Edemskiy, Chunxiang Xu
We consider the -error linear complexity of binary sequences derived from Eluer quotients modulo ( is an odd prime), recently introduced by J. Zhang and C. Zhao. We ad…
On error linear complexity of new generalized cyclotomic binary sequences of period
Chenhuang Wu, Chunxiang Xu, Zhixiong Chen +1
We consider the -error linear complexity of a new binary sequence of period , proposed in the recent paper "New generalized cyclotomic binary sequences of period ", by…
