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）是提出的比特幣OpCode（BIP-119），旨在介紹創建預定義的交易模板的能力，從而在加密貨幣中解鎖新的功能級別。

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.

比特幣開發人員討論的該提案試圖擴大比特幣交易的可能性，從而可以進行更複雜和有條件的交易。目的是實現這一目標，同時仍保持構成比特幣基礎的分散和安全的性質。

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.

儘管傳統的比特幣交易僅驗證了支出者擁有的支出權，但CTV通過設定如何花費這些輸出的條件來進一步邁出一步。

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.

本文將深入研究OP_CHECKTEMPLATEWATYIFY（OP_CTV）的機制，檢查其實際用例，突出其收益，討論其引入的風險，並提供對比特幣社區中正在進行的辯論的見解，從而對其潛在影響提供了平衡的視圖。

What is OP_CTV?

什麼是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.

正在為比特幣的腳本語言提出了一個新的OpCode。該操作碼（稱為CheckTemplateyify（OP_CTV））旨在引入使用預定義條件創建交易的功能。

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.

本質上，它將提前設置“基於模板”的支出條件，從而影響未來的產出。 OP_CTV的一個關鍵方面是，它允許用戶在無需鏈接信任或中間人的情況下執行支出條件的方式“鎖定”比特幣。

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

該屬性將有助於創建更高級的財務功能，例如保險庫，批處理付款和可擴展的支付渠道。

Who Introduced OP_CTV?

誰介紹了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.

該提出的OpCode，名為CheckTemplatewastififify（OP_CTV），是傑里米·魯賓（Jeremy Rubin）的創意。

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.

魯賓以對比特幣改進建議（BIPS）的貢獻而聞名，是加密貨幣社區的重要人物。目前，他專注於許多旨在增強比特幣功能的建議。

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.

這些建議的目的是擴大加密貨幣的能力。但是，關鍵優先事項是確保以保留其核心原則的方式對比特幣進行任何添加或修改。對最小整合的關注對於防止任何變化影響比特幣的分散性和安全性至關重要。

How OP_CTV Works: A Simplified Breakdown

OP_CTV的工作方式：簡化的故障

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.

從本質上講，OP_CTV將介紹擁有“盟約”的能力，即對如何花費比特幣的限制。它將通過創建對事務模板的哈希承諾來實現這一目標。如果支出交易與此模板不匹配，則將被網絡拒絕。

Example: Using OP_CTV for Vaults with Different Amounts

示例：使用op_ctv對具有不同數量的保險庫

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.

假設愛麗絲想花1個BTC，而鮑勃和查理則有不同的數量，她還想使用op_ctv設置一個為自己的更改設置保險庫。如果沒有OP_CTV，他們將需要依靠預先簽名的交易來實施這些未來的支出條件，這效率較低且不太安全。

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，可以使用承諾哈希，使愛麗絲可以設置這些條件，而無需存儲預先簽名的交易或與Bob，Charlie和支出時的更改地址進行交互。此靈活性是OP_CTV的關鍵優勢。

Potential Use Cases of OP_CTV

OP_CTV的潛在用例

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的真正優勢在於其能夠引入現有比特幣功能的更最佳和安全版本，或者創建全新功能而不冒險進入成熟智能合約領域的能力。對模塊化和與現有系統集成的關注對於無縫過渡和採用至關重要。

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

Debate Over OP_CTV: Simplicity vs. Advanced Functionality in Bitcoin

對OP_CTV的辯論：簡單性與比特幣中的高級功能

The upcoming introduction of a new opcode, CHECKTEMPLATEVERIFY (OP_CTV), is sparking lively discussion within the Bitcoin community. At the heart of the debate lies a fundamental question: should Bitcoin remain a simple, universally spendable asset, or should it adopt more advanced, condition-based spending capabilities?

即將推出的新OpCode CheckTemplateyify（OP_CTV）在比特幣社區中引發了活潑的討論。辯論的核心是一個基本的問題：比特幣應該仍然是一個簡單，可普遍的資產，還是應該採用更先進的基於條件的支出能力？

Those in favor of CTV highlight its role in unlocking new levels of functionality without significant additions to Bitcoin’s core design. They envision a future where CTV can be used to create more sophisticated financial applications on the Bitcoin blockchain.

那些贊成CTV的人強調了其在解鎖新水平功能中的作用，而沒有大量添加比特幣的核心設計。他們設想了一個未來，可以將CTV用於在比特幣區塊鏈上創建更複雜的財務應用程序。

Among the potential use cases that proponents envision are:
