區塊鏈或記錄鏈本質上是非對稱身份鏈
首發時間:2018-03-14
摘要:本文介紹了比特幣的定義、區塊鏈的定義及作用,指出"去中心化"并不是區塊鏈的特征,而只是比特幣的特征,并指出數字簽名算法和哈希函數算法是區塊鏈的核心技術所在,也是區塊鏈的創新發力點所在。文章討論了對稱身份與非對稱身份,闡述了區塊鏈本質上是一條非對稱身份鏈。設計和構建了高度中心化的記錄鏈,它被用來實現數字票據的可信傳遞,即保證轉讓過程中票據的真實性、不可篡改性和不可否認性。文章還比較了區塊鏈和記錄鏈的相同點與不同點,尤其,列舉了記錄鏈是量子安全的。

A Blockchain or Recordchain Is Essentially an Asymmetric Identity Chain
Abstract:This paper presents first the definition of a bitcoin, and the definition and effect of a blockchain. The paper points out that decentralization is not the characteristic of a blockchain, but the characteristic of a bitcoin, and that a digital signing algorithm and a hash function are not only the kernel techniques of a blockchain, but also the innovative knob of a blockchain. The paper discusses symmetric identities and asymmetric identities, and expounds that a blockchain is essentially an asymmetric identity chain. The paper designs and constructs a greatly centralized recordchain which is used to implement the trusted transference of a digital draft, namely to assure the authenticity, integrality, and undeniableness of a transferred digital draft. Lastly, the paper draw a comparison between a blockchain and a recordchain which includes samenesses and differences, and especially itemizes that a recordchain is quantum-safe.
Keywords: Bitcoin Blockchain Digital Signing Algorithm Hash function Asymmetric identity Digital draft Recordchain, Trusted transference Quantum security
