论文摘要
加密货币是分布式系统，可以在参与者中交换本机（和非）令牌。完整的历史簿记及其广泛的可用性开辟了前所未有的可能性，即了解其网络结构的演变，同时对用户行为与交换市场中的加密货币价格之间的关系有用。在此贡献中，我们回顾了有关比特币交易网络的结构属性的一些最新结果，这是一个通用名称，涉及一组不同的构造：比特币地址网络，比特币用户网络和比特币闪电网络。出现的图片是随着时间的推移而生长的系统，该系统变得越来越稀疏，其介观结构组织的特征是存在越来越重要的核心周围结构。这种特殊的拓扑与比特币的分布相匹配，这表明比特币正成为不同级别的越来越集中的系统。
Cryptocurrencies are distributed systems that allow exchanges of native (and non-) tokens among participants. The complete historical bookkeeping and its wide availability opens up an unprecedented possibility, i.e. that of understanding the evolution of their network structure while gaining useful insight on the relationships between user' behaviour and cryptocurrency pricing in exchange markets. In this contribution we review some of the most recent results concerning the structural properties of Bitcoin Transaction Networks, a generic name referring to a set of different constructs: the Bitcoin Address Network, the Bitcoin User Network and the Bitcoin Lightning Network. The picture that emerges is that of system growing over time, which becomes increasingly sparse and whose mesoscopic structural organization is characterised by the presence of an increasingly significant core-periphery structure. Such a peculiar topology is matched by a highly uneven distribution of bitcoins, a result suggesting that Bitcoin is becoming an increasingly centralized system at different levels.
