比特币的二元性：虚拟货币遇见触觉艺术

当您想到比特币时，您会想到一行行密码或闪亮的金属硬币吗？比特币的核心在于其数字形式

When you think of Bitcoin, do you imagine lines of cryptographic code or shiny metal coins? The heart of Bitcoin lies in its digital form, with complex algorithms governing its existence on the blockchain. Yet, there are tangible versions too, like Casascius Coins that bring a unique twist: their artistic designs conceal the private keys.

当您想到比特币时，您会想到一行行密码或闪亮的金属硬币吗？比特币的核心在于它的数字形式，复杂的算法控制着它在区块链上的存在。然而，也有有形的版本，比如卡萨修斯硬币，它带来了独特的变化：它们的艺术设计隐藏了私钥。

This duality of art and currency raises an intriguing question – how do these physical pieces relate to the Bitcoin you own or trade online? Let's explore the paradox where virtual currency and tactile art converge in unexpected ways.

艺术和货币的这种二元性提出了一个有趣的问题——这些实物作品与您拥有或在线交易的比特币有何关系？让我们探讨一下虚拟货币和触觉艺术以意想不到的方式融合的悖论。

The core of Bitcoin: What it looks like in code

比特币的核心：代码是什么样的

Bitcoin rests on a foundation of binary code that supports a decentralized ledger known as the blockchain.

比特币建立在二进制代码的基础上，支持称为区块链的去中心化账本。

At the core of this structure, transactions are stored as unspent transaction outputs (UTXOs), and Bitcoin wallet addresses are encoded in a compact, efficient way to guarantee secure ownership transfer.

在该结构的核心，交易被存储为未花费的交易输出（UTXO），比特币钱包地址以紧凑、高效的方式进行编码，以保证安全的所有权转移。

The blockchain code

区块链代码

Blockchain code is the foundation of Bitcoin, with thousands of lines crafted to execute its decentralized currency functions. I'll be honest, we're dealing with a digital marvel here. Bitcoin's existence is purely virtual, without any physical embodiment.

区块链代码是比特币的基础，有数千行代码来执行其去中心化货币功能。老实说，我们正在面对一个数字奇迹。比特币的存在纯粹是虚拟的，没有任何物理体现。

This digital code operates within the architecture of a thorough Bitcoin wallet, seamlessly translating binary digits into the functional elements of this cryptocurrency powerhouse.

该数字代码在完整的比特币钱包的架构内运行，将二进制数字无缝转换为该加密货币强大功能的功能元素。

The blockchain code is the core driving force. With around 77,000 lines of C++ code, the Bitcoin Core client orchestrates the entire operation.

区块链代码是核心驱动力。 Bitcoin Core 客户端使用大约 77,000 行 C++ 代码来协调整个操作。

You can think of it as a concert where every note (or line) must be perfectly timed to maintain harmony. Transactions are represented via UTXOs. They flow through the blockchain, a public ledger that's always evolving, thanks to Bitcoin mining.

您可以将其视为一场音乐会，其中每个音符（或线条）都必须完美配合才能保持和谐。交易通过 UTXO 表示。它们流经区块链，这是一个由于比特币挖矿而不断发展的公共分类账。

Cryptographic techniques, including the robust SHA-256 hashing algorithm, underpin the integrity and verification of blocks which shields the system from fraud.

加密技术（包括强大的 SHA-256 哈希算法）支撑了区块的完整性和验证，从而保护系统免受欺诈。

Bitcoin wallet address structure

比特币钱包地址结构

Bitcoin wallet addresses serve as the digital identity of your transactions on the blockchain. Each Bitcoin address is a string of 26 to 35 alphanumeric characters that uniquely identify your funds without giving away your entire transaction history. Think of it like your email address, or a bank account number, but specifically for receiving digital currency.

比特币钱包地址充当区块链上交易的数字身份。每个比特币地址都是由 26 到 35 个字母数字字符组成的字符串，可以唯一地标识您的资金，而不会泄露您的整个交易历史记录。您可以将其视为您的电子邮件地址或银行帐号，但专门用于接收数字货币。

Typically, these addresses start with a '1' or '3' for standard addresses, or 'bc1' for the more streamlined Bech32 addresses.

通常，这些地址以“1”或“3”开头（对于标准地址），或者以“bc1”（对于更精简的 Bech32 地址）开头。

The formation of a Bitcoin address is a fascinating process. It starts with a public key, which undergoes several cryptographic steps to become your wallet address. The address is then encoded with Base58Check, a method designed to weed out easily confused characters like '0' and 'O'. This helps prevent errors when inputting addresses so that your transactions go where you intend.

比特币地址的形成是一个令人着迷的过程。它以公钥开始，经过几个加密步骤才成为您的钱包地址。然后使用 Base58Check 对地址进行编码，这是一种旨在清除容易混淆的字符（例如“0”和“O”）的方法。这有助于防止输入地址时出现错误，以便您的交易按照您的意愿进行。

Before you use a Bitcoin address, I'd always suggest that you verify it with a small test transaction.

在使用比特币地址之前，我始终建议您通过小额测试交易来验证它。

Each address's uniqueness guarantees transactions are secure and transparent without compromising your privacy. This is at the core of what makes using Bitcoin a secure and efficient experience.

每个地址的唯一性保证交易安全和透明，而不会损害您的隐私。这是使使用比特币成为安全高效体验的核心。

Visual representations of Bitcoin in the digital space

比特币在数字空间中的视觉表现

In the digital domain, Bitcoin is often symbolized by the ubiquitous BTC.

在数字领域，比特币常常以无处不在的BTC作为象征。

When using digital wallets and exchanges, you'll notice Bitcoin's presence through interfaces that facilitate transactions, capture market trends, and portray account information.

使用数字钱包和交易所时，您会通过促进交易、捕捉市场趋势和描绘帐户信息的界面注意到比特币的存在。

Bitcoin symbols and logos

比特币符号和标志

The Bitcoin symbol BTC (with two vertical strokes) signifies one of the most revolutionary shifts in finance. It reflects Bitcoin's core as a digital asset, separating it from traditional currencies.

比特币符号 BTC（有两个竖线）标志着金融领域最具革命性的转变之一。它反映了比特币作为数字资产的核心，将其与传统货币区分开来。

Bitcoin's official logo complements the symbol: an orange circle featuring the white "B" with those defining vertical lines. The whole logo is usually slightly slanted to the right:

比特币的官方标志与这个符号相得益彰：一个橙色圆圈，上面有白色的“B”和垂直线。整个标志通常稍微向右倾斜：

This logo is straightforward but bold. It's easily recognizable in a sea of digital assets. With branding that leans into modern fonts and technology-aligned colors, Bitcoin reinforces its role as a forward-thinking financial icon. 

这个标志简单但大胆。它在数字资产的海洋中很容易被识别。通过采用现代字体和技术色彩的品牌，比特币强化了其作为具有前瞻性的金融标志的作用。

Bitcoin in wallets and exchanges

钱包和交易所中的比特币

When you open a digital wallet, you won't see a graphical depiction of Bitcoin itself. Instead, the interface showcases your balance, transaction histories, and QR codes.

当您打开数字钱包时，您不会看到比特币本身的图形描述。相反，该界面会显示您的余额、交易历史记录和二维码。

What you see are Bitcoin's public and private keys, stored securely within the application, yet unseen by the naked eye. It's an invisible gateway to your virtual assets.

您看到的是比特币的公钥和私钥，安全地存储在应用程序中，但肉眼看不见。它是您虚拟资产的无形门户。

Each transaction you make logs into the blockchain as unspent transaction outputs (UTXOs), which is visualized through ledgers rather than physical coins.

您进行的每笔交易都会作为未花费的交易输出（UTXO）记录到区块链中，这是通过分类账而不是物理硬币来可视化的。

Wallets don't depict Bitcoin as traditional currency symbols; instead, Bitcoin exists as unique identifiers, like alphanumeric wallet addresses. 

钱包并不将比特币描绘成传统的货币符号；而是将比特币视为传统的货币符号。相反，比特币作为唯一标识符存在，就像字母数字钱包地址一样。

Physical Bitcoin: A tangible representation

实物比特币：有形的表现

So, if the real Bitcoin is not tangible, does physical Bitcoin even exist? The answer is, surprisingly, yes.

那么，如果真正的比特币不是有形的，那么实物比特币还存在吗？令人惊讶的是，答案是肯定的。

Several companies made physical Bitcoin in its early years, but among these, Casascius Coins were the most popular, made by the company of the same name. They offered tangible tokens enhanced with artistic designs and security features like holog

早年有几家公司生产过实物比特币，但其中最受欢迎的是由同名公司生产的 Casascius 硬币。他们提供通过艺术设计和全息等安全功能增强的有形代币
