聯合挖礦徹底改變了加密貨幣挖礦：增強安全性並節省成本

合併挖礦是一種使用相同的共識協議和哈希函數同時挖掘多種加密貨幣的技術。透過將較小的加密貨幣與較大的加密貨幣合併，合併挖礦可以增強安全性，同時降低營運成本。這種做法自2011 年以來一直受到關注，著名的例子包括狗狗幣（與萊特幣合併）、Rootstock（比特幣）和亦來雲（比特幣），展示了小型區塊鏈網路的成本效益和增強安全性的優勢。

Merged Mining: Enhancing Security and Cost-Efficiency in Cryptocurrency Mining

聯合挖礦：增強加密貨幣挖礦的安全性和成本效率

Merged mining, an innovative technique in the realm of blockchain technology, allows cryptocurrencies to simultaneously mine two or more digital assets. This novel approach leverages the computational power of miners working on a "parent" blockchain to validate blocks on a "child" blockchain, offering significant benefits to smaller cryptocurrencies and the mining ecosystem as a whole.

合併挖礦是區塊鏈技術領域的創新技術，允許加密貨幣同時挖掘兩個或多個數位資產。這種新穎的方法利用在「父」區塊鏈上工作的礦工的計算能力來驗證「子」區塊鏈上的區塊，為較小的加密貨幣和整個採礦生態系統提供了顯著的好處。

Mechanism of Merged Mining

聯合挖礦機制

For merged mining to occur, the participating cryptocurrencies must adhere to the same consensus protocol and employ the same hash function. Once these prerequisites are met, miners can utilize their Proof-of-Work (PoW) efforts on the parent blockchain to also validate transactions on the child blockchain. In return for this additional work, miners receive rewards in the form of the child blockchain's native cryptocurrency.

為了進行合併挖礦，參與的加密貨幣必須遵守相同的共識協議並使用相同的雜湊函數。一旦滿足這些先決條件，礦工就可以利用其在父區塊鏈上的工作證明（PoW）工作來驗證子區塊鏈上的交易。作為這項額外工作的回報，礦工將獲得子區塊鏈原生加密貨幣形式的獎勵。

This process effectively maximizes miners' efforts, as they can contribute to securing multiple networks while optimizing their computational resources. Moreover, it strengthens the security of smaller blockchain networks, reducing their susceptibility to malicious attacks, such as 51% attacks.

這個過程有效地最大化了礦工的努力，因為他們可以在優化其計算資源的同時有助於保護多個網路。此外，它還增強了小型區塊鏈網路的安全性，降低了其遭受惡意攻擊（例如 51% 攻擊）的可能性。

Advantages of Merged Mining

聯合挖礦的優勢

Increased Security: By leveraging the hashing power of larger, established blockchains, merged mining enhances the security of smaller cryptocurrencies. This increased security helps protect against malicious activity and provides a more stable mining environment.

提高安全性：透過利用較大的、已建立的區塊鏈的雜湊能力，合併挖礦增強了較小加密貨幣的安全性。這種增強的安全性有助於防止惡意活動並提供更穩定的挖掘環境。

Cost-Efficiency: Merged mining eliminates the need for miners to invest in additional hardware or modify their existing setups to mine multiple cryptocurrencies. This approach significantly reduces operational costs, making mining more economically viable.

成本效益：合併採礦消除了礦工投資額外硬體或修改現有設定來開採多種加密貨幣的需要。這種方法顯著降低了營運成本，使採礦更加經濟可行。

Increased Earning Potential: Miners can amplify their earnings by receiving rewards from both the parent and child blockchains. This dual income stream provides additional incentives for miners to participate in the merged mining process.

增加收入潛力：礦工可以透過從父區塊鏈和子區塊鏈獲得獎勵來擴大收入。這種雙重收入流為礦工參與合併挖礦過程提供了額外的誘因。

Historical Adoption of Merged Mining

聯合挖礦的歷史採用

The concept of merged mining was first introduced in 2011 by Namecoin, which utilized the Bitcoin blockchain as its parent blockchain. Since then, numerous other cryptocurrencies have adopted this technique, including:

聯合挖礦的概念由 Namecoin 於 2011 年首次提出，該公司利用比特幣區塊鏈作為其母區塊鏈。從那時起，許多其他加密貨幣都採用了這種技術，包括：

Dogecoin (Merged with Litecoin)

狗狗幣（與萊特幣合併）

Dogecoin, a popular meme coin, implemented merged mining in 2014 to bolster its network security. Miners simultaneously mine Dogecoin alongside Litecoin, the parent blockchain that employs the Scrypt hashing algorithm.

狗狗幣是一種受歡迎的迷因幣，它於 2014 年實施了合併挖礦，以增強其網路安全性。礦工們同時開採狗狗幣和萊特幣，萊特幣是採用 Scrypt 哈希演算法的母區塊鏈。

Rootstock (Merged with Bitcoin)

Rootstock（與比特幣合併）

Rootstock (RSK), a smart contract platform, harnesses the hashing power of the Bitcoin network to secure its blockchain. Bitcoin miners can validate blocks on both the Bitcoin and Rootstock blockchains, benefiting from Rootstock's security without additional computational work.

Rootstock (RSK) 是一個智慧合約平台，利用比特幣網路的雜湊能力來保護其區塊鏈。比特幣礦工可以驗證比特幣和 Rootstock 區塊鏈上的區塊，無需額外的運算工作即可受益於 Rootstock 的安全性。

Elastos (Merged with Bitcoin)

亦來雲（與比特幣合併）

Elastos, a blockchain platform, utilizes merged mining with Bitcoin as one of its consensus mechanisms. Miners who successfully mine a block on the Bitcoin blockchain can reference a valid block on the Elastos main chain, linking the two blockchains and leveraging Bitcoin's security.

亦來雲端是一個區塊鏈平台，利用與比特幣的聯合挖礦作為其共識機制之一。成功開採比特幣區塊鏈上的區塊的礦工可以引用亦來雲端主鏈上的有效區塊，連結兩個區塊鏈並利用比特幣的安全性。

Conclusion

結論

Merged mining has emerged as a powerful tool in the cryptocurrency landscape. By enabling smaller cryptocurrencies to leverage the security and cost-effectiveness of larger blockchains, this innovative technique strengthens the overall blockchain ecosystem. Miners benefit from increased earning potential, while users enjoy enhanced security for their digital assets. As the cryptocurrency industry continues to evolve, merged mining is poised to play an increasingly significant role in shaping its future.
