重新抵押：2008 年危機的加密貨幣迴聲引發擔憂

2008 年金融危機之後，重新抵押已成為加密貨幣領域的常見做法。這種做法類似於傳統金融中的再抵押，涉及利用鎖定資產來產生額外收入。儘管它在以太坊上獲得了關注，但人們仍然擔心潛在的系統性風險。隨著重新抵押擴大到 Solana，行業專家表達了熱情和懷疑，支持者強調增強安全性，批評者則強調相互關聯的金融系統的複雜性和潛在陷阱。

Consensus Magazine: Restaking Gains Traction in Ethereum and Solana, Raising Concerns

共識雜誌：重新抵押在以太坊和 Solana 中獲得關注，引發擔憂

The global financial crisis of 2008, sparked by the reckless practices of Lehman Brothers, served as a stark reminder of the perils of excessive financial leverage. A decade later, the cryptocurrency industry has witnessed the emergence of a novel practice known as restaking, which bears striking similarities to the fateful rehypothecation schemes that contributed to the financial meltdown.

2008年由雷曼兄弟的魯莽行為引發的全球金融危機清楚提醒人們過度金融槓桿的危險。十年後，加密貨幣產業出現了一種被稱為「重新質押」的新穎做法，這種做法與導致金融崩潰的致命的再抵押計畫有著驚人的相似之處。

Restaking: The Cryptocurrency Equivalent of Rehypothecation

重新質押：加密貨幣相當於再抵押

In the context of traditional finance, rehypothecation refers to the practice of pledging an asset as collateral multiple times, effectively creating the illusion of increased liquidity. This practice can lead to a chain reaction of financial instability if the underlying asset loses value.

在傳統金融背景下，再抵押是指多次質押資產作為抵押品的做法，有效地製造流動性增加的假象。如果標的資產貶值，這種做法可能會導致金融不穩定的連鎖反應。

Restaking, as practiced in the cryptocurrency realm, operates in a similar manner. In proof-of-stake blockchains like Ethereum, users known as validators stake their cryptocurrency holdings to secure the network and earn rewards for their contributions. However, staked assets are typically locked up, limiting their liquidity.

加密貨幣領域的實踐中，重新抵押以類似的方式運作。在以太坊等權益證明區塊鏈中，被稱為驗證者的用戶將持有的加密貨幣進行質押，以確保網路安全並為其貢獻賺取獎勵。然而，質押資產通常被鎖定，限制了其流動性。

Restaking platforms like EigenLayer have emerged to address this issue by creating derivatives that allow validators to unlock the value of their staked assets without compromising their staking position. This practice enables validators to earn additional revenue on top of the standard staking rewards.

像 EigenLayer 這樣的重新抵押平台已經出現，透過創建衍生性商品來解決這個問題，這些衍生性商品允許驗證者在不損害其抵押地位的情況下釋放其抵押資產的價值。這種做法使驗證者能夠在標準質押獎勵之外獲得額外收入。

Billions of Dollars at Stake: Solana's Foray into Restaking

數十億美元面臨風險：Solana 進軍重新抵押

The popularity of restaking has surged in recent months, with billions of dollars worth of Ethereum (ETH) being restaked. The practice is now gaining traction on Solana (SOL) as well, with several firms, including the blockchain's leading player, Jito (JTO), exploring its possibilities.

近幾個月來，重新質押的受歡迎程度激增，價值數十億美元的以太坊（ETH）被重新質押。這種做法現在也在 Solana (SOL) 上受到關注，包括區塊鏈領先者 Jito (JTO) 在內的多家公司正在探索其可能性。

Debating the Risks and Benefits of Restaking

討論重新抵押的風險和收益

While proponents argue that restaking can enhance the security of Solana-based applications, critics raise concerns over the potential systemic risks it introduces. They point to the 2008 financial crisis as a cautionary tale, demonstrating how excessive leverage and interconnectedness can spiral into a catastrophic cascade of defaults.

儘管支持者認為重新抵押可以增強基於 Solana 的應用程式的安全性，但批評者對其引入的潛在系統性風險表示擔憂。他們指出 2008 年的金融危機是一個警示故事，顯示過度槓桿和相互關聯性如何會導致災難性的一連串違約。

MetaMask 的新工具：對抗 MEV 的威脅

In a related development, MetaMask, the ubiquitous Ethereum wallet, has introduced a new feature aimed at protecting its users from a practice known as MEV. MEV, short for maximal extractable value, refers to the practice of validators strategically manipulating the order in which transactions are added to a blockchain to maximize their profits.

在相關開發中，無處不在的以太坊錢包 MetaMask 引入了一項新功能，旨在保護其用戶免受 MEV 行為的影響。 MEV 是最大可提取價值的縮寫，是指驗證者策略性地操縱交易添加到區塊鏈的順序以最大化其利潤的做法。

MEV: A Lucrative but Controversial Practice

MEV：一種有利可圖但有爭議的做法

MEV has become a contentious topic in the cryptocurrency industry, with some embracing it as a legitimate profit-making opportunity and others condemning it as unethical and harmful to the integrity of the blockchain. MetaMask's new feature is designed to mitigate the risks associated with MEV by protecting users from predatory traders.

MEV 已成為加密貨幣行業中一個有爭議的話題，有些人將其視為合法的獲利機會，而另一些人則譴責其不道德且有害於區塊鏈的完整性。 MetaMask 的新功能旨在透過保護用戶免受掠奪性交易者的侵害來降低與 MEV 相關的風險。

Conclusion: A Lesson from History

結論：歷史的教訓

The cryptocurrency industry is still in its formative stages, and the long-term consequences of restaking and MEV remain uncertain. However, the historical parallels to the 2008 financial crisis serve as a stark reminder of the potential dangers of unchecked financial innovation. As the cryptocurrency ecosystem continues to evolve, it is imperative to carefully consider the risks and benefits of new practices to avoid repeating the mistakes of the past.

加密貨幣產業仍處於形成階段，重新抵押和 MEV 的長期後果仍然不確定。然而，與 2008 年金融危機的歷史相似之處清楚地提醒人們，不受控制的金融創新存在潛在危險。隨著加密貨幣生態系統的不斷發展，必須仔細考慮新做法的風險和利益，以避免重蹈過去的錯誤。
