比特币的扩容演变：揭开革命性的契约

比特币中的契约实施旨在通过允许多个用户共享基础链上未花费交易输出（UTXO）的所有权来解决可扩展性和交易成本的限制。这种创新功能类似于预签名交易，但通过共识强制执行，允许更多用户参与网络，而无需增加链上交易量。通过承诺对 UTXO 支出的特定限制，契约为比特币第 2 层解决方案提供了增强的安全性和功能，有可能为数字资产的更广泛采用和可扩展性释放新的可能性。

Bitcoin's Evolutionary Imperative: Scaling Through Covenants

比特币的进化势在必行：通过契约进行扩展

Bitcoin, the revolutionary digital currency designed to challenge traditional financial systems, has reached a juncture where its scaling capabilities are paramount. As transaction fees on the base layer continue to soar, rendering the network inaccessible to many users, Bitcoin advocates recognize the urgent need for an update. Enter covenants, a transformative solution poised to significantly enhance Bitcoin's scalability and unlock its full potential.

比特币是一种旨在挑战传统金融体系的革命性数字货币，它的扩容能力已经到了至关重要的时刻。随着基础层的交易费用持续飙升，导致许多用户无法访问该网络，比特币倡导者认识到迫切需要进行更新。契约是一种变革性的解决方案，有望显着增强比特币的可扩展性并释放其全部潜力。

Unveiling the Intricacies of Covenants

揭开契约的复杂性

Covenants, a diverse set of mechanisms, introduce a novel approach to managing Unspent Transaction Outputs (UTXOs) among multiple users. By incorporating specific restrictions on how future UTXOs can be utilized, covenants emulate the functionality of pre-signed transactions while leveraging consensus for enforcement.

契约是一组多样化的机制，它引入了一种管理多个用户之间未花费交易输出（UTXO）的新颖方法。通过纳入对未来 UTXO 的使用方式的具体限制，契约模拟了预签名交易的功能，同时利用共识来执行。

好处多多：扩展比特币的功能

The implementation of covenants empowers Bitcoin users to assert ownership of their bitcoins directly on the base chain, paving the way for enhanced functionality on Layer 2 solutions. This groundbreaking feature enables multiple parties to share UTXOs securely and efficiently, unleashing a plethora of innovative applications.

契约的实施使比特币用户能够直接在基础链上主张其比特币的所有权，为第 2 层解决方案的增强功能铺平了道路。这一突破性的功能使多方能够安全高效地共享 UTXO，从而释放出大量的创新应用。

Unraveling the Misconceptions: A Deeper Dive

澄清误解：深入探讨

Debunking the prevalent misunderstandings surrounding Bitcoin, Shinobi, a self-taught visionary, sheds light on the shortcomings of relying solely on Layer 2 solutions for scaling purposes. While Layer 2 protocols like the Lightning Network undoubtedly enhance transaction throughput, their dependency on the base layer remains a fundamental bottleneck.

Shinobi 这位自学成才的梦想家揭穿了围绕比特币的普遍误解，揭示了仅依靠第 2 层解决方案来实现扩容的缺点。虽然像闪电网络这样的第 2 层协议无疑会提高交易吞吐量，但它们对基础层的依赖仍然是一个根本瓶颈。

The Need for Base Layer Enhancements

基础层增强的需要

To unlock the true potential of Layer 2 solutions, Shinobi underscores the crucial need for base layer enhancements. By implementing features like covenants, Bitcoin can facilitate trustless anchoring of Layer 2 protocols, eliminating the reliance on custodians and fostering a more robust and secure ecosystem.

为了释放第 2 层解决方案的真正潜力，Shinobi 强调了基础层增强的迫切需要。通过实施契约等功能，比特币可以促进第 2 层协议的去信任锚定，消除对托管人的依赖，并培育更强大、更安全的生态系统。

揭开契约：外行指南

To simplify the complexities of covenants, Shinobi offers a simplified explanation. Each covenant, akin to a script or address associated with bitcoins, outlines specific criteria that must be met before a transaction can be executed. These criteria range from providing a signature to adhering to predetermined time locks, ensuring secure and controlled spending of funds.

为了简化盟约的复杂性，忍者提供了一个简化的解释。每个契约类似于与比特币相关的脚本或地址，概述了执行交易之前必须满足的特定标准。这些标准包括从提供签名到遵守预定的时间锁定，确保资金支出的安全和受控。

CTV: Committing to the Future

CTV：致力于未来

Among the diverse covenant proposals, Shinobi highlights CheckTemplateVerify (CTV) as a particularly promising solution. CTV allows users to commit to a hash of a future transaction, creating a pre-signed transaction that can be executed later without requiring on-chain confirmation. By chaining multiple UTXOs together through CTV, users can open numerous Lightning channels with a single on-chain transaction, dramatically enhancing scalability.

在多样化的契约提案中，Shinobi 强调 CheckTemplateVerify (CTV) 是一个特别有前途的解决方案。 CTV 允许用户提交未来交易的哈希值，创建一个可以稍后执行的预签名交易，无需链上确认。通过 CTV 将多个 UTXO 链接在一起，用户可以通过单个链上交易打开多个闪电通道，从而显着增强可扩展性。

TapleafUpdateVerify: Streamlining Exiting

TapleafUpdateVerify：简化退出

TapleafUpdateVerify, another noteworthy covenant proposal, addresses the complexities of exiting a shared UTXO. Unlike CTV, TapleafUpdateVerify allows users to safely exit a UTXO in a single transaction, ensuring fair distribution of funds and preventing double spending.

TapleafUpdateVerify 是另一个值得注意的契约提案，它解决了退出共享 UTXO 的复杂性。与 CTV 不同，TapleafUpdateVerify 允许用户在单笔交易中安全退出 UTXO，确保资金公平分配并防止双重支出。

Potential Pitfalls: Weighing the Risks

潜在陷阱：权衡风险

While covenants offer immense potential, Shinobi acknowledges the importance of considering potential risks. TapleafUpdateVerify, in particular, could inadvertently facilitate the creation of drivechains, sidechains that operate independently of the Bitcoin blockchain. This could potentially undermine Bitcoin's security and stability.

虽然契约提供了巨大的潜力，但忍者承认考虑潜在风险的重要性。特别是 TapleafUpdateVerify 可能会无意中促进独立于比特币区块链运行的驱动链和侧链的创建。这可能会破坏比特币的安全性和稳定性。

Maintaining Motivation Amidst Discord

在不和谐中保持动力

Despite the negativity and disagreements that often permeate the Bitcoin community, Shinobi remains optimistic about the future. He believes that the growing dissatisfaction with dogmatic narratives and simplistic viewpoints will ultimately lead to more productive and nuanced discussions. This shift will foster collaboration and innovation, propelling Bitcoin towards its full potential.

尽管比特币社区经常弥漫着消极和分歧，Shinobi 对未来仍然保持乐观。他认为，对教条式叙述和简单化观点日益增长的不满最终将导致更加富有成效和细致入微的讨论。这一转变将促进协作和创新，推动比特币充分发挥其潜力。

Conclusion: Embracing Evolution

结论：拥抱进化

Covenants represent a transformative step in Bitcoin's evolution. By addressing the scaling challenges faced by the base layer, covenants pave the way for increased adoption and the realization of Bitcoin's transformative potential. As the community embraces this technological advancement, Bitcoin will continue to redefine the world of finance, empowering individuals and shaping the future of our digital landscape.

契约代表了比特币发展过程中的变革性一步。通过解决基础层面临的扩展挑战，契约为增加比特币的采用和实现比特币的变革潜力铺平了道路。随着社区接受这一技术进步，比特币将继续重新定义金融世界，赋予个人权力并塑造我们数字景观的未来。
