AI总结：
针对跨链商业中资产锁定带来的财务风险，提出稳定币系统CroCoDai，通过高效支持多区块链并增强对价格波动与平台故障的弹性，实现低开销的跨链交易。
摘要：
去中心化金融（DeFi）在无需可信中介的情况下交换数字资产，其价值近年来迅速增长。全球DeFi生态系统分裂为多个区块链，激发了跨链商业的需求。现有的跨链交易方法（如桥接和跨链交易）通过将资产锁定在托管中来实现原子性。然而，锁定资产增加了参与者的财务风险，特别是由于价格波动和跨链交易的较长延迟。稳定币与美元等非波动性资产挂钩，有助于缓解与价格波动相关的风险。然而，现有的稳定币设计绑定于单个区块链平台，需要可信方或复杂协议在区块链之间交换稳定币代币。我们的目标是为跨链商业设计一种实用的稳定币。实现这一目标需要应对两个挑战。第一个挑战是高效支持大量且不断增长的区块链。第二个挑战是对价格波动和区块链平台故障具有弹性。我们提出CroCoDai来解决这些挑战。我们还提出了稳定币系统的三个原型实现，并表明其执行开销较小。
英文摘要：
Decentralized Finance (DeFi), in which digital assets are exchanged without trusted intermediaries, has grown rapidly in value in recent years. The global DeFi ecosystem is fragmented into multiple blockchains, fueling the demand for cross-chain commerce. Existing approaches for cross-chain transactions, e.g., bridges and cross-chain deals, achieve atomicity by locking assets in escrow. However, locking up assets increases the financial risks for the participants, especially due to price fluctuations and the long latency of cross-chain transactions. Stablecoins, which are pegged to a non-volatile asset such as the US dollar, help mitigate the risk associated with price fluctuations. However, existing stablecoin designs are tied to individual blockchain platforms, and trusted parties or complex protocols are needed to exchange stablecoin tokens between blockchains. Our goal is to design a practical stablecoin for cross-chain commerce. Realizing this goal requires addressing two challenges. The first challenge is to support a large and growing number of blockchains efficiently. The second challenge is to be resilient to price fluctuations and blockchain platform failures. We present CroCoDai to address these challenges. We also present three prototype implementations of our stablecoin system, and show that it incurs small execution overhead.
