Zero-knowledge Based Proof-chain: A methodology for blockchain-partial system

Yuqi Bai; Lei Luo; Shixin Liang
Subjects: Computer Science >> Computer Software

Intuitively there is drastic distinction between the “pure” decentralized block-chain systems like Defis and those that only utilizes block-chain as an enhancing technology but remains centralized with real-world business model and conventional technologies like database, application server etc. Our study explores extensively this distinction from a methodological point of view, classifies them into blockchain-complete and blockchain-partial, analyzes key features of the two types, and reveal the root cause of this distinction. We analyze the function or, in more strong words, the “ultimate purpose” of blockchain in the blockchain-partial systems, and present a conceptual model we named proof-chain that quite satisfactorily represented the general paradigm of blockchain in blockchain-partial systems. A universal tension between strength of proof-chain and privacy is then revealed and the zero-knowledge based proof-chain takes shape. Several case studies demonstrate the explaining power of our proof-chain methodology. We then apply proof-chain methodology to the analysis of the ecosystem of a collaborating group of blockchain-partial systems, representing the paradigm of public and private data domain whose border the proof-chain crosses. Finally, some derived guidelines from this methodology speaks usefulness of our methodology.

关于信息容量的研究

许建峰
Subjects: Information Science and Systems Science >> Basic Disciplines of Information Science and Systems Science

[目的] 分析基于信息六元组模型的信息容量定义和性质,提出信息与物质、能量和时间的关系公式,为信息科学特别是量子信息科技应用提供理论参照。

[方法] 基于客观信息论提出的信息六元组模型,结合量子信息理论,通过严格的数学公理化方法,研究了多种组合条件下的信息容量效应,推导了信息容量与质量、能量和时间的关系。

[结果] 证明了利用信息熵定义信息容量仅仅是客观信息论所定义信息容量的一种特例,估算了单个量子载体所能承载的信息容量,推导给出信息与物质、能量和时间的关系公式,并以此计算和分析了迄今为止宇宙可能承载的信息容量。

[局限] 相关理论方法需要在物理学实证研究和复杂信息系统科学应用中得到验证。

[结论] 客观信息论的信息容量内涵能够较为深刻和准确地揭示客观世界物质、能量、和信息三大组成要素之间的相互关系,具有很好的普适意义和应用前景。

On dark matter

Xian-Qiao Yu
Subjects: Physics >> The Physics of Elementary Particles and Fields

In this article, I shall propose an enlightening view on the origin of dark matter abundance, in which I introduce a neutral primordial field, which is a new field beyond the standard model, the mass of the primordial field is confined in the vicinity of neutrino mass (or 1-2 orders of magnitude different from the neutrino mass). All the standard model elementary particles are produced spontaneously from this field in the Big Bang epoch of the universe and then these produced elementary particles decayed or annihilated in the well-known standard model interactions. The relic of the primordial field appears in a form of vacuum energy can not only give naturally the correct abundance of dark matter in the present universe, but provide a natural solution to the cosmological constant problem as well. We find that the conventional methods of detecting dark matter either fail or have great difficulties to detect the remaining vacuum energy of the primordial field, and how to confirm the existence of the remaining energy of the universe's original energy in experiment is still an open problem.

具有Lp度量的模糊集空间的性质

黄欢
Subjects: Mathematics >> Mathematics (General)

In this paper, we discuss the properties of  the spaces of fuzzy sets in a metric space with $L_p$-type $d_p$ metrics, $p\geq 1$. Firstly, we give the characterizations of compactness in fuzzy set space with $d_p$ metrics. Then we present the completions of fuzzy set spaces with $d_p$ metrics.
The $d_p$ metrics are well-defined if and only if a function induced by the Hausdorff metric is measurable. In this paper, we give some fundamental conclusions on the measurability of this function. This paper was submitted to Fuzzy Sets and Systems on 2022.05.06.
