论文摘要
在加密货币中，交易费用通常仅以本地平台货币支付。这种限制会引起广泛的挑战，例如用户经验恶化，分散申请的强制性租金支付以及区块链社区竞争（例如，共同依据）。理想情况下，在真正的无许可区块链中，应通过所谓的元交易措施在任何其他加密货币中应支付交易费用。在本文中，我们将元交易正式化，回顾现有思想，并描述新颖的Metatataction设计方法。在假设有足够的市场流动性的假设下，我们认为元交易并不能降低加密货币平台的安全性。但是，在不更改基础区块链的情况下，元交易设计通常会增加交易成本并减少区块链交易吞吐量。
In cryptocurrencies, transaction fees are typically exclusively paid in the native platform currency. This restriction causes a wide range of challenges, such as deteriorated user experience, mandatory rent payments by decentralized applications, and blockchain community rivalries (e.g., coinism). Ideally, in a truly permissionless blockchain, transaction fees should be payable in any other cryptocurrency via so-called metatransactions. In this paper, we formalize metatransactions, review existing ideas, and describe novel metatransaction design approaches. Under the assumption of sufficient market liquidity, we argue that metatransactions do not lower the security of cryptocurrency platforms. However, without changing the underlying blockchain, metatransaction designs typically increase transaction costs and reduce the blockchain transaction throughput.
