论文摘要
在公共分布式分类帐技术（DLT）中，例如区块链，节点可以随时加入并离开网络。当连接网络想要检索分类帐的当前状态时，就会发生重大挑战。的确，该节点可能会从诚实和拜占庭节点中收到相互矛盾的信息，因此很难识别当前状态。在本文中，我们对无状态的协议感兴趣，即，新的加入节点应该能够使用表征分类帐的固定数据（例如比特币中的Genesis Block）来检索分类帐的当前状态。我们定义了三种无状态DLT的变体：弱，强和概率。然后，我们使用不同类型的共识分析DLT的此属性。
In public distributed ledger technologies (DLTs), such as Blockchains, nodes can join and leave the network at any time. A major challenge occurs when a new node joining the network wants to retrieve the current state of the ledger. Indeed, that node may receive conflicting information from honest and Byzantine nodes, making it difficult to identify the current state. In this paper, we are interested in protocols that are stateless, i.e., a new joining node should be able to retrieve the current state of the ledger just using a fixed amount of data that characterizes the ledger (such as the genesis block in Bitcoin). We define three variants of stateless DLTs: weak, strong, and probabilistic. Then, we analyze this property for DLTs using different types of consensus.
