比特币序数：它们是什么？它们如何工作？为什么它们很重要？

比特币序数是比特币对 NFT 的回答，允许将数据刻录到特定的聪（比特币的百万分之一）上，从而使该聪与其他聪不同或不可替代。

Bitcoin has come a long way since launching in 2009 as a fairly obscure form of digital cash. The project would go relatively unnoticed by the general public for several years, gaining popularity in 2013 and skyrocketing to become the largest asset class in the world.

自 2009 年推出以来，比特币作为一种相当默默无闻的数字现金形式已经取得了长足的进步。该项目在几年内相对不被公众注意到，在 2013 年受到欢迎，并飙升成为世界上最大的资产类别。

In fact, while Bitcoin was the first-ever cryptocurrency, its invention prompted thousands of new cryptocurrencies to follow suit, with complex use cases, expansive derivative markets, and a growing list of features added on. Bitcoin developers have also continued to innovate on the project, with the biggest update in recent years being Bitcoin Ordinals, which rolled out in 2023.

事实上，虽然比特币是有史以来第一个加密货币，但它的发明促使数千种新的加密货币纷纷效仿，其复杂的用例、广阔的衍生品市场以及越来越多的功能都被添加进来。比特币开发者也在该项目上不断创新，近年来最大的更新是于 2023 年推出的比特币 Ordinals。

Here's a quick guide on what Bitcoin Ordinals are, how they work, and how to buy them. We'll also cover some real-world examples and use cases of Bitcoin Ordinals. Finally, we'll discuss some potential challenges and downsides of Bitcoin Ordinals.

以下是关于比特币序号是什么、它们如何工作以及如何购买它们的快速指南。我们还将介绍比特币序数的一些现实示例和用例。最后，我们将讨论比特币序号的一些潜在挑战和缺点。

What are Bitcoin Ordinals? Bitcoin Ordinals explained

什么是比特币序数？比特币序数解释

Bitcoin Ordinals are Bitcoin’s answer to NFTs, allowing a way of inscribing data onto a specific satoshi (one-millionth of a bitcoin) in a way that makes that satoshi distinct from others or non-fungible.

比特币序数是比特币对 NFT 的回答，允许将数据刻录到特定的聪（比特币的百万分之一）上，从而使该聪与其他聪不同或不可替代。

So why is this important?

那么为什么这很重要呢？

Originally, Bitcoin was launched as a fungible form of digital cash. Like a US dollar, one is much the same as the other as far as the people transacting are concerned. However, Bitcoin Ordinals allow users to identify satoshis from one another.

最初，比特币是作为一种可替代的数字现金形式推出的。就像美元一样，就交易者而言，一种货币与另一种美元非常相似。然而，比特币序号允许用户相互识别聪。

For example, a collector might be interested in owning a satoshi from a crucial moment in Bitcoin’s history, like the Bitcoin halving that takes place every four years, and thus be willing to spend more than the market value of one satoshi to buy it.

例如，收藏家可能有兴趣拥有比特币历史上关键时刻的一枚聪，例如每四年发生一次的比特币减半，因此愿意花费超过一枚聪的市场价值来购买它。

This leads Bitcoin into the realm of digital collectables and NFTs. The Ethereum NFT (non-fungible token) market exploded in 2021, with over $24 billion in sales of NFTs. These NFTs are typically digital assets on the Ethereum network with unique identifying numbers and were used to represent ownership of assets like art and music.

这将比特币带入数字收藏品和 NFT 领域。以太坊 NFT（不可替代代币）市场在 2021 年爆发，NFT 销售额超过 240 亿美元。这些 NFT 通常是以太坊网络上的数字资产，具有唯一的识别号码，用于代表艺术和音乐等资产的所有权。

Bitcoin Ordinals could be used for exactly the same thing, with the added benefit of being associated with the most popular and long-standing cryptocurrency on the market.

比特币序数可以用于完全相同的事情，而且还有与市场上最受欢迎和历史最悠久的加密货币相关联的额外好处。

How do Bitcoin Ordinals work?

比特币序数如何运作？

Bitcoin Ordinals assign a unique identifier number to the satoshis in any given bitcoin. Bitcoin developer Casey Rodarmor introduced the idea in 2023 and used a feature of Bitcoin’s 2021 Taproot upgrade, which allowed for data to be stored directly on the Bitcoin blockchain to make it happen.

比特币序号为任何给定比特币中的聪分配一个唯一的标识符号。比特币开发商 Casey Rodarmor 在 2023 年提出了这个想法，并使用了比特币 2021 Taproot 升级的一个功能，该功能允许将数据直接存储在比特币区块链上以实现这一目标。

Ordinals work by making each unit of a single bitcoin uniquely identifiable. When a bitcoin is mined, all one million satoshis are assigned a number in the order of their creation. Satoshis can be tracked individually across multiple wallets, meaning you can spend BTC and still keep track of individual satoshis or Ordinals.

序数的工作原理是使单个比特币的每个单位都具有唯一的可识别性。当比特币被开采时，所有 100 万聪都会按照其创建的顺序分配一个数字。 Satoshis 可以在多个钱包中单独跟踪，这意味着您可以花费 BTC 并且仍然跟踪单个 satoshis 或 Ordinals。

Whereas Ethereum NFTs sometimes require metadata to be stored off-chain, sometimes on a traditional web2 website, Bitcoin Ordinal data is all stored on-chain, reducing the risk of data loss. The SegWit and Taproot updates to the Bitcoin network allow for a lot of data to be stored in this manner.

以太坊 NFT 有时需要将元数据存储在链下，有时需要存储在传统的 web2 网站上，而比特币 Ordinal 数据全部存储在链上，从而降低了数据丢失的风险。比特币网络的 SegWit 和 Taproot 更新允许以这种方式存储大量数据。

Buying, selling, and trading Bitcoin Ordinals

购买、出售和交易比特币序号

To buy Bitcoin Ordinals, you’ll need to use a wallet that is compatible with Taproot addresses. Many of the most popular Bitcoin wallets, such as Trust Wallet, Mycelium, and Blockchain.com wallets, do not support this feature. You can use wallets like Sparrow Wallet instead.

要购买比特币序号，您需要使用与 Taproot 地址兼容的钱包。许多最受欢迎的比特币钱包，例如 Trust Wallet、Mycelium 和 Blockchain.com 钱包，不支持此功能。您可以使用 Sparrow Wallet 等钱包代替。

Bitcoin addresses that are compatible with taproot usually start with the characters ‘bc1p’.

与主根兼容的比特币地址通常以字符“bc1p”开头。

How to buy Bitcoin Ordinals

如何购买比特币序号

With your wallet set up, you can visit marketplaces like Ordinals Market or OpenOrdex to take a look at the ordinals on offer. As with Ethereum NFTs, these ordinals will often be associated with the sale of digital artwork or other assets.

设置好钱包后，您可以访问 Ordinals Market 或 OpenOrdex 等市场来查看所提供的序数。与以太坊 NFT 一样，这些序数通常与数字艺术品或其他资产的销售相关。

Deposit your funds to the platform (at your own risk) or connect your BTC wallet. From there, bid on an Ordinal or simply make a direct purchase.

将您的资金存入平台（风险自负）或连接您的 BTC 钱包。从那里，对序号进行竞标或直接进行购买。

That’s how it’s done! You can also list Ordinals for sale on the same platform or trade them peer-to-peer with other users.

就是这样完成的！您还可以在同一平台上列出待售序数或与其他用户进行点对点交易。

Real-world examples and use cases

现实世界的示例和用例

Bitcoin Ordinals can be used to represent the sale of digital or real-world assets, to act as a collectable piece of BTC network history, or to permanently inscribe data to an immutable blockchain as a form of censorship-resistant art, protest, or historic preservation.

比特币序号可用于代表数字或现实世界资产的销售，充当 BTC 网络历史的可收藏片段，或将数据永久刻录到不可变的区块链上，作为抗审查艺术、抗议或历史的形式。保存。

At the moment, the main use case lies in artwork, much like with Ethereum NFTs. The market for Bitcoin Ordinals is relatively small, although not insignificant. Sales of BTC Ordinals reached over $170 million in March 2024.

目前，主要用例在于艺术品，就像以太坊 NFT 一样。比特币序号的市场相对较小，但也并非微不足道。 2024 年 3 月，BTC Ordinals 的销售额超过 1.7 亿美元。
