綠色加密的興起：可持續區塊鍊和能源效率革命

在環境問題，投資者壓力和技術創新的驅動下，開發商和社區正在積極努力為數字資產建立更環保的未來。

The world of cryptocurrency is often associated with dazzling digital fortunes and cutting-edge technology. But beneath the surface, a significant environmental question mark has loomed: the massive energy consumption of some popular cryptocurrencies. For years, headlines have focused on Bitcoin’s electricity usage, sometimes comparing it to entire countries.

加密貨幣的世界通常與令人眼花digital亂的數字命運和尖端技術有關。但是在表面之下，一個重要的環境問號已隱約：一些流行的加密貨幣的大量能源消耗。多年來，頭條新聞一直集中在比特幣的電力上，有時將其與整個國家進行比較。

However, a powerful counter-movement is emerging - the rise of “green crypto” and sustainable blockchain initiatives. Driven by environmental concerns, investor pressure, and technological innovation, developers and communities are actively working to build a more eco-friendly future for digital assets. From energy-sipping technologies to projects that directly fund environmental causes, the crypto landscape is undergoing a green transformation. This article explores this shift, examining the technologies enabling it, the leading sustainable projects, and how even casual crypto users can get involved.

但是，有強大的反向運動正在出現 - “綠色加密”和可持續區塊鏈計劃的興起。在環境問題，投資者壓力和技術創新的驅動下，開發商和社區正在積極努力為數字資產建立更環保的未來。從能源措施技術到直接資助環境原因的項目，加密貨幣景觀正在經歷綠色轉化。本文探討了這一轉變，研究了實現它的技術，領先的可持續項目，以及連續加密用戶如何參與其中。

The Energy Elephant in the Room: Understanding Proof-of-Work

房間中的能量大象：了解工作證明

To understand why green crypto is necessary, we need to look at the technology behind early cryptocurrencies like Bitcoin. Many operate using a system called Proof-of-Work (PoW). Think of PoW as a complex mathematical puzzle-solving contest. Computers worldwide (called miners) race to solve these puzzles to validate transactions and add them to the blockchain, a shared digital ledger. The first miner to find the solution is rewarded with new cryptocurrency.

要了解為什麼需要綠色加密貨幣，我們需要查看像比特幣這樣早期加密貨幣背後的技術。許多人使用稱為工作證明（POW）的系統進行操作。將POW視為一場複雜的數學拼圖解決競賽。全球計算機（稱為礦工）競賽解決這些難題以驗證交易，並將它們添加到一個共享的數字分類帳中的區塊鏈中。第一個找到解決方案的礦工將獲得新的加密貨幣。

If you’re curious about what a “hash” is, this video by Ken Sheriff shows it done by hand, whereas modern miners do this multiple trillions of times a second!

如果您對“哈希”是什麼好奇，那麼肯·警長（Ken Sheriff）的這段視頻顯示了手工完成的視頻，而現代礦工每秒進行了數万億次！

While secure, this process requires immense computational power, which translates directly into high electricity consumption. As the value of cryptocurrencies like Bitcoin rose, more powerful computers joined the mining network, driving energy demand even higher. Studies, like a 2022 White House report, estimated that global crypto assets using PoW could generate between 110 and 170 million metric tons of carbon dioxide annually – comparable to the emissions of some entire nations. This significant environmental footprint raised alarms among environmentalists, regulators, and even leaders within the tech industry.

在安全的同時，此過程需要巨大的計算能力，這直接轉化為高電力消耗。隨著比特幣等加密貨幣的價值，更強大的計算機加入了採礦網絡，使能源需求更高。研究，例如2022年白宮報告，估計使用POW的全球加密資產每年可能產生110至1.7億噸二氧化碳的二氧化碳，與某些整個國家的排放相媲美。這種重要的環境足跡在環保主義者，監管機構甚至科技行業的領導者中引起了警報。

The Green Shift: Energy-Efficient Technologies Emerge

綠色轉移：能節能技術出現

The good news is that the crypto world is actively developing and adopting greener alternatives to PoW. The most prominent shift is towards Proof-of-Stake (PoS).

好消息是，加密貨幣世界正在積極發展並採用更綠色的POW替代品。最突出的轉變是朝著二手證明（POS）。

Instead of solving energy-intensive puzzles, PoS relies on a different mechanism to validate transactions. In a PoS system, individuals or groups “stake” their own cryptocurrency as collateral. The network then chooses validators from this pool, often based on the amount staked and other factors, to confirm transactions and create new blocks. Because it doesn’t require massive computational power, PoS is dramatically more energy-efficient.

POS並沒有解決能源密集型難題，而是依賴於驗證交易的不同機制。在POS系統中，個人或團體將自己的加密貨幣“股權”作為抵押品。然後，該網絡通常是根據固定數量和其他因素來從此池中選擇驗證器，以確認交易並創建新的塊。由於它不需要大量的計算能力，因此POS效率更高。

The most significant example of this shift was Ethereum’s “Merge,” which occurred in September 2022. Ethereum, the second-largest cryptocurrency and the backbone for thousands of decentralized applications (dApps) and NFTs, transitioned from PoW to PoS. The result was staggering: Ethereum’s energy consumption plummeted by an estimated 99.95% or more almost overnight. This move demonstrated that even major, established blockchains could successfully adopt greener technology.

這一轉變的最重要例子是以太坊的“合併”，發生在2022年9月。結果令人震驚：以太坊的能源消耗估計幾乎在一夜之間下降了99.95％或更多。這一舉動表明，即使是主要的，建立的區塊鏈也可以成功採用綠色技術。

Beyond PoS, other innovative consensus mechanisms are contributing to the green wave:

除了POS之外，其他創新共識機制也有助於綠波：

• Hashgraph: This technology, used by Hedera Hashgraph, boasts extremely high throughput and low energy consumption, making it suitable for large-scale, scalable blockchain networks.

•Hashgraph：Hedera Hashgraph使用的這項技術具有極高的吞吐量和低能消耗，使其適用於大規模，可擴展的區塊鍊網絡。

• Hyperledger Fabric: Primarily used for enterprise blockchain solutions, Hyperledger Fabric offers a flexible and efficient framework for building custom blockchain networks with minimal environmental footprint.

•HyperLeDger織物：HyperLeDger Fabric主要用於企業區塊鏈解決方案，為建立具有最小環境足蹟的自定義區塊鍊網絡提供了靈活，有效的框架。

• Chainlink’s decentralized oracle networks provide a crucial link between smart contracts and external data sources in a highly secure and energy-efficient manner.

•ChainLink的分散Oracle網絡以高度安全和節能的方式提供了智能合約與外部數據源之間的關鍵聯繫。
