论文摘要
未进行的交易输出(UTXO)模型通常在分布式分类帐技术(DLT)领域用于参与者之间传输价值。它的优点之一是它允许并行处理交易,因为可以按任何顺序添加独立交易。订单不变性和并行性的属性在可伸缩性方面具有潜在的好处。但是,由于UTXO分类帐是一种仅附加数据结构,因此由于存在冲突的交易而损害了此优势。我们提出了一个扩展的UTXO分类帐模型,该模型可以乐观地更新分类帐,并跟踪可能的冲突的依赖性。在存在冲突机制的情况下,我们提出了一种将扩展的分类帐恢复为一致的UTXO分类帐的方法。
The Unspent Transaction Output (UTXO) model is commonly used in the field of Distributed Ledger Technology (DLT) to transfer value between participants. One of its advantages is that it allows parallel processing of transactions, as independent transactions can be added in any order. This property of order invariance and parallelisability has potential benefits in terms of scalability. However, since the UTXO Ledger is an append-only data structure, this advantage is compromised through the presence of conflicting transactions. We propose an extended UTXO Ledger model that optimistically updates the ledger and keeps track of the dependencies of the possible conflicts. In the presence of a conflict resolution mechanism, we propose a method to reduce the extended ledger back to a consistent UTXO Ledger.
