OP_CHECKTEMPLATEVERIFY (OP_CTV) is a proposed Bitcoin opcode (BIP-119) that aims to introduce the capability for creating predefined transaction templates, unlocking new levels of functionality within the cryptocurrency.

OP_CHECKTEMPLATERATEW（OP_CTV）是提出的比特币OpCode（BIP-119），旨在介绍创建预定义的交易模板的能力，从而在加密货币中解锁新的功能级别。

This proposal, being discussed by Bitcoin developers, seeks to expand the possibilities of Bitcoin transactions, allowing for more complex and conditional transactions. The goal is to achieve this while still maintaining the decentralized and secure nature that forms the foundation of Bitcoin.

比特币开发人员讨论的该提案试图扩大比特币交易的可能性，从而可以进行更复杂和有条件的交易。目的是实现这一目标，同时仍保持构成比特币基础的分散和安全的性质。

While traditional Bitcoin transactions only verify that the spender possesses the right to spend, CTV goes a step further by setting conditions on how these outputs can be spent.

尽管传统的比特币交易仅验证了支出者拥有的支出权，但CTV通过设定如何花费这些输出的条件来进一步迈出一步。

This article will delve into the mechanics of OP_CHECKTEMPLATEVERIFY (OP_CTV), examining its practical use cases, highlighting its benefits, discussing the risks it introduces and providing insight into the ongoing debate within the Bitcoin community, offering a balanced view of its potential impact.

本文将深入研究OP_CHECKTEMPLATEWATYIFY（OP_CTV）的机制，检查其实际用例，突出其收益，讨论其引入的风险，并提供对比特币社区中正在进行的辩论的见解，从而对其潜在影响提供了平衡的视图。

What is OP_CTV?

什么是OP_CTV？

A new opcode is being proposed for Bitcoin’s scripting language. This opcode, known as CHECKTEMPLATEVERIFY (OP_CTV), aims to introduce the capability for transactions to be created with predefined conditions.

正在为比特币的脚本语言提出了一个新的OpCode。该操作码（称为CheckTemplateyify（OP_CTV））旨在引入使用预定义条件创建交易的功能。

Essentially, it will enable “template-based” spending conditions to be set in advance, impacting how outputs can be spent in the future. A key aspect of OP_CTV is that it allows users to "lock up" Bitcoin in a way where the spending conditions can be enforced without the need for on-chain trust or intermediaries.

本质上，它将提前设置“基于模板”的支出条件，从而影响未来的产出。 OP_CTV的一个关键方面是，它允许用户在无需链接信任或中间人的情况下执行支出条件的方式“锁定”比特币。

This property will facilitate the creation of more advanced financial functions, such as vaults, batch payments, and scalable payment channels.

该属性将有助于创建更高级的财务功能，例如保险库，批处理付款和可扩展的支付渠道。

Who Introduced OP_CTV?

谁介绍了OP_CTV？

This proposed opcode, named CHECKTEMPLATEVERIFY (OP_CTV), is the brainchild of Jeremy Rubin, a well-known Bitcoin developer and advocate for the cryptocurrency’s development and innovation.

该提出的OpCode，名为CheckTemplatewastififify（OP_CTV），是杰里米·鲁宾（Jeremy Rubin）的创意。

Known for his contributions to Bitcoin Improvement Proposals (BIPs), Rubin is a prominent figure in the cryptocurrency community. He is currently focused on a number of proposals that aim to enhance the functionality of Bitcoin.

鲁宾以对比特币改进建议（BIPS）的贡献而闻名，是加密货币社区的重要人物。目前，他专注于许多旨在增强比特币功能的建议。

The goal of these proposals is to expand the capabilities of the cryptocurrency. However, a key priority is to ensure that any additions or modifications to Bitcoin are done in a way that preserves its core principles. This focus on minimal integration is crucial to prevent any changes from impacting the decentralized and secure nature of Bitcoin.

这些建议的目的是扩大加密货币的能力。但是，关键优先事项是确保以保留其核心原则的方式对比特币进行任何添加或修改。对最小整合的关注对于防止任何变化影响比特币的分散性和安全性至关重要。

How OP_CTV Works: A Simplified Breakdown

OP_CTV的工作方式：简化的故障

In essence, OP_CTV will introduce the ability to have "covenants," which are conditions that place constraints on how Bitcoin can be spent. It will achieve this by creating a hash commitment to a transaction template. If a spending transaction does not match this template, it will be rejected by the network.

从本质上讲，OP_CTV将介绍拥有“盟约”的能力，即对如何花费比特币的限制。它将通过创建对事务模板的哈希承诺来实现这一目标。如果支出交易与此模板不匹配，则将被网络拒绝。

Key Components of CTV

CTV的关键组件

Example: Using OP_CTV for Vaults with Different Amounts

示例：使用op_ctv对具有不同数量的保险库

Suppose Alice wants to spend 1 BTC, with different amounts going to Bob and Charlie, and she also wants to set up a vault for her change using OP_CTV. Without OP_CTV, they would need to rely on pre-signed transactions to enforce these future spending conditions, which is less efficient and less secure.

假设爱丽丝想花1个BTC，而鲍勃和查理则有不同的数量，她还想使用op_ctv设置一个为自己的更改设置保险库。如果没有OP_CTV，他们将需要依靠预先签名的交易来实施这些未来的支出条件，这效率较低且不太安全。

However, with OP_CTV, it will be possible to use commitment hashes, allowing Alice to set these conditions without needing to store pre-signed transactions or interact with Bob, Charlie, and the change address at the time of spending. This flexibility is a key advantage of OP_CTV.

但是，使用OP_CTV，可以使用承诺哈希，使爱丽丝可以设置这些条件，而无需存储预先签名的交易或与Bob，Charlie和支出时的更改地址进行交互。此灵活性是OP_CTV的关键优势。

Potential Use Cases of OP_CTV

OP_CTV的潜在用例

The true strength of OP_CTV lies in its ability to introduce more optimal and secure versions of existing Bitcoin functions, or to create entirely new capabilities without venturing into the realm of full-fledged smart contracts. This focus on modularity and integration with existing systems is crucial for a seamless transition and adoption.

OP_CTV的真正优势在于其能够引入现有比特币功能的更最佳和安全版本，或者创建全新功能而不冒险进入成熟智能合约领域的能力。对模块化和与现有系统集成的关注对于无缝过渡和采用至关重要。

Here are some of the potential use cases that are being discussed:
