论文摘要
在许多典型的应用程序方案中，有必要撤销由用户错误操作，财务欺诈，非法黑客攻击等不正确的帐户操作。不幸的是，用户经常模糊“交易状态可撤销”和“可撤销事务状态”的概念之间的界限，从而导致目前在Blockchain Systems中未能在Blockchain Systems中获得重复的交易。在这项工作中，我们提出了Gatechain，这是一个支持分布式分类帐中可撤销交易模型（RTM）的区块链。具体而言，基于最先进的区块链技术，Gatechain可以通过利用改进的帐户模型和额外设计的交易类型来安全地撤回帐户状态更改操作。在此基础上，Gatechain利用功能完整性，易于部署和较低的复杂性的特征。
In many typical application scenarios, it is necessary to revoke the incorrect account operations caused by user mis-operation, financial fraud, illegal hacking, etc. Unfortunately, users often blur the lines between the concept of "transaction state revocable" and "business status revocable", which result in revocable transaction not universally supported in blockchain systems at present. In this work, we propose GateChain , a blockchain that support revocable transaction model (RTM) on distributed ledger. Specifically, based on the state-of-the-art blockchain technologies, GateChain can safely withdraw the account status change operations by leveraging an improved account model and extra designed transaction types. On that basis, GateChain exploit the characteristics of functional completeness, easy to deployment and lower complexity.
