PayPal 推出绿色采矿计划以应对比特币的环境影响

PayPal 与 Energy Web 和 DMG Blockchain 合作，为采用清洁能源实践的比特币矿工实施激励措施。绿色矿业倡议旨在通过提供“可持续性证明”认证并向使用低碳能源的矿工提供额外的比特币奖励来减少对环境的影响，鼓励向环保的比特币采矿过渡。

PayPal Embarks on Green Mining Initiative to Mitigate Bitcoin's Environmental Impact

PayPal 启动绿色采矿计划，以减轻比特币对环境的影响

In a significant effort to address the environmental concerns surrounding Bitcoin mining, PayPal has partnered with Energy Web and DMG Blockchain Solutions to implement a groundbreaking incentive mechanism aimed at encouraging miners to adopt sustainable energy sources. This move represents a crucial step towards decarbonizing the Bitcoin network while preserving the integrity of its decentralized and secure architecture.

为了解决围绕比特币挖矿的环境问题，PayPal 与 Energy Web 和 DMG Blockchain Solutions 合作实施了一项突破性的激励机制，旨在鼓励矿工采用可持续能源。此举代表着比特币网络脱碳的关键一步，同时保持其去中心化和安全架构的完整性。

Bitcoin's Energy Conundrum

比特币的能源难题

Bitcoin's Proof of Work (PoW) consensus mechanism, which ensures the integrity and security of the network, has come under scrutiny due to its reliance on energy-intensive mining operations. As the Cambridge Bitcoin Electricity Consumption Index estimates, Bitcoin mining currently contributes approximately 85 million metric tons of carbon dioxide emissions annually.

比特币的工作量证明（PoW）共识机制可确保网络的完整性和安全性，但由于其对能源密集型挖矿业务的依赖而受到密切关注。据剑桥比特币电力消耗指数估计，比特币挖矿目前每年排放约 8500 万吨二氧化碳。

Recognizing the need to mitigate this environmental footprint while maintaining Bitcoin's viability, PayPal has embraced a pragmatic approach. The company acknowledges that Bitcoin is unlikely to abandon its PoW mechanism in the foreseeable future, necessitating innovative solutions to address its energy consumption.

贝宝认识到需要在保持比特币生存能力的同时减轻这种环境足迹，因此采取了务实的方法。该公司承认，在可预见的未来，比特币不太可能放弃其 PoW 机制，因此需要创新的解决方案来解决其能源消耗问题。

Incentivizing Green Miners

激励绿色矿工

PayPal's Green Mining Initiative, outlined in a detailed report, proposes the utilization of cryptoeconomic incentives to encourage miners to embrace low-carbon energy sources. This mechanism involves the development of a "clean energy validation platform" by Energy Web, a web3 energy infrastructure provider.

贝宝的绿色采矿计划在一份详细报告中概述，建议利用加密经济激励措施来鼓励矿工采用低碳能源。该机制涉及web3能源基础设施提供商Energy Web开发的“清洁能源验证平台”。

The platform issues "green keys" to Bitcoin miners who demonstrate verifiable proof of utilizing a substantial proportion of low-carbon energy sources in their operations. Miners' eligibility is determined through a comprehensive scoring system.

该平台向比特币矿工发放“绿色钥匙”，这些矿工必须出示可验证的证据，证明在其运营中使用了大量低碳能源。矿工的资格是通过综合评分系统确定的。

This accreditation enables network participants to designate a portion of validator rewards exclusively to green keyholders, incentivizing miners to join the platform and adopt sustainable practices.

这项认证使网络参与者能够将一部分验证者奖励专门指定给绿色密钥持有者，从而激励矿工加入该平台并采用可持续实践。

Preferential Transaction Routing

优先交易路由

To further bolster the adoption of green energy, PayPal has devised a preferential transaction routing mechanism. On-chain transactions are prioritized for routing to green miners by broadcasting them with reduced transaction fees, but with an additional Bitcoin (BTC) reward "locked" in a multi-signature payout address.

为了进一步促进绿色能源的采用，PayPal 设计了优惠交易路由机制。链上交易优先路由到绿色矿工，通过以较低的交易费用进行广播，但额外的比特币（BTC）奖励“锁定”在多重签名支付地址中。

This mechanism incentivizes green miners to process these transactions since they are the only ones eligible for the extra BTC reward. In contrast, regular miners are discouraged from processing these transactions due to their low transaction fees.

这种机制激励绿色矿工处理这些交易，因为他们是唯一有资格获得额外 BTC 奖励的人。相比之下，由于交易费用较低，普通矿工不鼓励处理这些交易。

Trial Success

试用成功

PayPal has conducted successful trials in collaboration with DMG Blockchain Solutions, broadcasting low-fee transactions to Bitcoin's mempool during periods of varying on-chain volumes. Results indicate that regular miners either declined or experienced significant delays in validating these transactions, while DMG was able to identify and validate a transaction intended for green key holders.

PayPal 与 DMG 区块链解决方案合作进行了成功的试验，在链上交易量不同的时期向比特币内存池广播低费用交易。结果表明，普通矿工要么拒绝验证这些交易，要么经历严重延迟，而 DMG 能够识别并验证针对绿色密钥持有者的交易。

Long-Term Decarbonization Goal

长期脱碳目标

The Green Mining Initiative aims to catalyze a long-term decarbonization of the Bitcoin network by financially rewarding miners who embrace sustainable energy practices. This approach is expected to reduce Bitcoin's ecological footprint while preserving its fundamental characteristics as a decentralized and secure cryptocurrency.

绿色矿业倡议旨在通过向采用可持续能源实践的矿工提供经济奖励，促进比特币网络的长期脱碳。这种方法预计将减少比特币的生态足迹，同时保留其作为去中心化和安全加密货币的基本特征。

Positive Market Response

市场反应积极

The partnership has garnered positive attention in the cryptocurrency market, particularly for Energy Web, whose EWT token has experienced a significant surge in value. This indicates the growing appetite among investors for solutions that address the environmental concerns associated with cryptocurrency mining.

此次合作在加密货币市场获得了积极关注，尤其是 Energy Web，其 EWT 代币的价值大幅飙升。这表明投资者对解决与加密货币挖矿相关的环境问题的解决方案的兴趣日益浓厚。

Environmental Concerns over Proof of Work

对工作量证明的环境担忧

The rise of cryptocurrency in recent years has coincided with increasing concerns regarding the energy consumption of PoW networks, particularly Bitcoin. Comparisons have been drawn between Bitcoin's ecological footprint and the carbon emissions of entire countries.

近年来，加密货币的兴起恰逢人们对 PoW 网络（尤其是比特币）能源消耗的日益担忧。人们将比特币的生态足迹与整个国家的碳排放量进行了比较。

These concerns have drawn criticism from politicians such as U.S. Democratic Senators, international organizations like the International Monetary Fund, and business leaders including Elon Musk and Intel CEO Pat Gelsinger.

这些担忧引起了美国民主党参议员等政界人士、国际货币基金组织等国际组织以及埃隆·马斯克和英特尔首席执行官帕特·基辛格等商界领袖的批评。

Ethereum's Shift to Proof of Stake

以太坊向权益证明的转变

Notably, Ethereum, another prominent cryptocurrency, transitioned from PoW to Proof of Stake (PoS) consensus in September 2022, leading to a dramatic reduction in its energy consumption. PoS is a less energy-intensive consensus mechanism that does not require rigorous mining operations.

值得注意的是，另一种著名的加密货币以太坊于 2022 年 9 月从 PoW 共识过渡到股权证明（PoS）共识，导致其能源消耗大幅减少。 PoS 是一种能源消耗较低的共识机制，不需要严格的挖矿操作。

PayPal's Green Mining Initiative represents a significant step towards addressing the environmental challenges associated with Bitcoin mining. By incentivizing miners to adopt clean energy sources, PayPal and its partners aim to mitigate Bitcoin's ecological footprint while upholding its decentralized and secure nature. This initiative has the potential to reshape the cryptocurrency industry and contribute to a more sustainable future for digital assets.

贝宝的绿色采矿计划是解决与比特币采矿相关的环境挑战的重要一步。通过激励矿工采用清洁能源，PayPal 及其合作伙伴旨在减轻比特币的生态足迹，同时维护其去中心化和安全的性质。这一举措有可能重塑加密货币行业，并为数字资产创造更可持续的未来做出贡献。
