与 USDT 或 USDC 不同，DAI 稳定币的价值以 1:1 的比例与美元挂钩，无需实物储备。MakerDAO 使借款人能够通过存入抵押品产生 DAI。支持的抵押品包括以太坊 (ETH)、Wrapped Bitcoin (WBTC)、ETH-Staked ETH Liquidity Pair on Curve v1 (CRVV1ETHSTETH)、Wrapped stETH (WSTETH) 以及其他 10 多种加密货币。

DAI 的一个显著特点是它是一种算法稳定币。由于 MakerDAO 聪明的智能合约设计，其价值在整个存在期间始终保持在 1 美元。这种设计规定了接受哪些抵押品、相应的抵押比率以及偿还贷款时 DAI 的销毁。因此，MakerDAO 保留了对 DAI 流通供应的控制权，因此也保留了对其价值的控制权。

DAI 稳定币设计的一个重要方面是过度抵押。规定抵押品必须超过所发放的伤残津贴金额的 100%以上，这对降低贷款人的违约风险至关重要。这种方法直接解决了加密货币价值波动的问题，从而维持了 DAI 与美元之间的挂钩，保障了贷款人资产的价值。

MakerDAO 稳定币如何运作？

贷款

为了启动 DAI 稳定币的发行，借款人需要存入抵押品，从而产生新的 DAI。在归还原数额的 DAI 时，借款人的抵押物将被归还，归还的 DAI 将被销毁，以防止流通代币数量过多。由于潜在的套利活动，借款人可能会赚取比原始金额更多的 DAI，从而可以保留差额。

清算

如果借款人未能偿还 DAI 贷款或抵押率低于规定水平，就会进行清算。超额抵押规则规定，抵押品与DAI 的比率必须始终超过 100%，例如，wBTC 为 175%。这意味着，如果借款人存入 175 美元的比特币，他们将获得 100 美元的 DAI 贷款，剩余的 75 美元将用于上述极端情况。为了保护系统免受减值贷款的影响，任何人都可以触发合同上的清算功能，并获得一定比例的余额作为奖励。

是什么决定了 MakerDAO 稳定币的价格？

Dai 稳定币是去中心化金融（DeFi）生态系统中的一个重要角色，其价值来源于一个复杂的系统，该系统旨在尽可能保持 Dai 以美元计价的当前价格稳定。这个由 MakerDAO 设计的以太坊区块链智能合约系统利用抵押债务头寸（CDP）来确定 Dai 的价值。用户可以将 ETH 等资产锁定在这些 CDP 中，这些 CDP 具有超额抵押，从而确保戴美元的价格保持稳定。例如，如果您锁定了价值 300 美元的 ETH，那么您最多可以用 Dai 借到抵押物价值的 66%，抵押率保持在 150%。这种超额抵押对傣族的物价稳定起着关键作用。

如果你曾经问过 "Dai 目前的价格是多少？"或者 "Dai 的价格会上涨吗？"，答案可以在其强大的管理和技术架构中找到。实时 Dai 价格是智能合约、MKR 代币持有者管理和自动市场机制的复杂结果。所有这些因素都使 Dai 成为加密货币领域最可靠的资产之一，经常引发关于 2023 年及以后 Dai 价格预测的讨论。因此，对于任何对稳定币或 Dai 价格分析感兴趣的人来说，了解正在发挥作用的复杂系统至关重要。

结论

总之，MakerDAO 稳定币（DAI）是 DeFi 的一个关键项目，它提供了一种与美元挂钩的去中心化稳定解决方案。其创新的算法设计和超额抵押确保了稳定性和可靠性，使其成为去中心化金融生态系统的推动力。

值得注意的是，与其他加密货币一样，MakerDAO Stablecoin 也有其自身的风险，因此在投资时最好自己进行研究并谨慎行事。

独特性

DAI’s main advantage lies in its soft peg to the price of the U.S. dollar.

The crypto market is notorious for its volatility with even the largest, highly-liquid coins such as Bitcoin sometimes experiencing price changes (both up and down) of 10% or more within a single day. Under these circumstances, traders and investors are naturally predisposed to add safe-haven assets to their portfolios, whose stable price might help offset significant market fluctuations.

One such kind of asset are stablecoins, of which DAI is one example. These are cryptocurrencies whose price is pegged to assets with a relatively stable value — most commonly traditional fiat currencies, such as USD or EUR.

Another key advantage of DAI is the fact that it is managed not by a private company, but rather by a decentralized autonomous organization via a software protocol. As a result, all instances of issuance and burning of tokens are managed and publicly recorded by Ethereum-powered self-enforcing smart-contracts, making the entire system more transparent and less prone to corruption.

In addition, the process of developing DAI software is governed in a more democratic way — via direct voting by the regular participants of the token’s ecosystem.

代币效应

A decentralized digital economy needs stable money in order to function. $DAI is a price-stable asset that can be used as a medium of exchange, store of value, and unit of account. $DAI enables a wide range of financial activities and applications that have previously been untenable due to the volatility of legacy cryptocurrencies like Bitcoin. People can obtain $DAI by buying it from brokers or exchanges, or simply by receiving it as a means of payment. Once generated, bought, or received, $DAI can be used in the same manner as any other cryptocurrency: it can be sent to others, used as payments for goods and services, and even held as savings through a feature of the Maker Protocol called the Dai Savings Rate (DSR).
