【Abstract】Over the last few years, the interest in blockchain platforms has fostered the implementation of a number of distributed ledger-based solutions for the exchange of information, assets and digitized goods in both the private and the public sectors. While proposing promising alternatives to the original Bitcoin protocol is an important goal that the bulk of the effort in blockchain community has been focused on, it may not be enough. A major challenge faced by blockchain systems goes beyond the ability to superficially explore their attack surface, and firstly must consider the importance of studying the functioning of their underlying consensus protocols also in the form of non-functional properties such as security and safety. It is to this extent that recent research has started to rigorously analyze the Bitcoin protocol and its close variants, whilst BET-like systems have not received equal attention so far. In this paper, we focus on the XRP Ledger with the aim to lay down the first steps towards the complete formalization of its unique consensus mechanism. We provide a thorough description of its different phases and present an analysis of some of its properties, which will be suitable as a basis for future research in the same vein.

【摘要】在过去几年中，对区块链平台的兴趣促进了许多基于分布式账本的解决方案的实施，用于在私营和公共部门交换信息、资产和数字化商品。虽然提出原始比特币协议的有希望的替代方案是区块链社区的大部分努力都集中在的一个重要目标，但这可能还不够。区块链系统面临的一个主要挑战超出了表面探索其攻击面的能力，首先必须考虑研究其底层共识协议的功能的重要性，也包括安全性和安全性等非功能属性的形式。正是在这个程度上，最近的研究已经开始严格分析比特币协议及其紧密变体，而迄今为止类似 BET 的系统尚未受到同等关注。在本文中，我们专注于 XRP 账本，旨在为其独特的共识机制的完全形式化奠定第一步。我们对它的不同阶段进行了全面的描述，并对它的一些特性进行了分析，这将适合作为未来同样研究的基础。
