比特币OP_RETURN元数据分析
An analysis of Bitcoin OP_RETURN metadata
摘要：
比特币协议允许通过脚本语言的特殊指令（称为OP_RETURN）将任意数据保存在区块链上。越来越多的协议利用这一特性，将比特币区块链的应用范围扩展到货币转移之外。比特币社区中的一个争论点是，通过OP_RETURN加载数据是否会对比特币网络的主要目标产生负面影响。本文是对OP_RETURN多年来使用情况的实证研究。我们确定了几个协议的基础上OP_RETURN，我们分类的应用领域。我们测量每个协议的使用时间的演变，OP_RETURN事务的应用程序域的分布，以及它们的空间消耗。
英文摘要：
The Bitcoin protocol allows to save arbitrary data on the blockchain through a special instruction of the scripting language, called OP_RETURN. A growing number of protocols exploit this feature to extend the range of applications of the Bitcoin blockchain beyond transfer of currency. A point of debate in the Bitcoin community is whether loading data through OP_RETURN can negatively affect the performance of the Bitcoin network with respect to its primary goal. This paper is an empirical study of the usage of OP_RETURN over the years. We identify several protocols based on OP_RETURN, which we classify by their application domain. We measure the evolution in time of the usage of each protocol, the distribution of OP_RETURN transactions by application domain, and their space consumption.
