摘　　要：为了在非持续连通的容迟网络部署区块链,设计了可运行于该网络的区块链贸易机制。首先,将标志位引入现有的区块数据结构上,提出了可用于追加网络非联通状态生成区块的附链存储结构;其次,提出了附链区块贸易打包方法、挖掘方法和共识方法;最后,提出了避免附链追加过程中区块欺诈的确认共识方法。通过理论证明和实验分析可知,提出的机制可实现在容迟网络中支持区块链贸易。In order to deploy a blockchain on the non-continuous connectivity delay tolerant network,a blockchain trading mechanism was designed,which could run on this type of network.First,the identifier was introduced into the existing block structure and a block structure on the attached chain was presented,which could append the blocks generated during network disconnection.Then,the approaches including the block package,block mining and block consensus on the attached chain were proposed.Finally,a confirming consensus approach was presented to avoid block fraud in the process of appending the attached chain.Through theoretical proof and experimental analysis,the proposed mechanism can support blockchain trading in the delay tolerant network.
