比特币诞生 16 周年：公布 2100 万比特币供应上限

加密货币市场可能正处于动荡之中，但今天提供了一个停下来反思的理由。距离中本聪已经整整16年了

Cryptocurrency market may be in turmoil, but today marks a moment in history that deserves a pause and reflection. It has been exactly 16 years since Satoshi Nakamoto, Bitcoin's (BTC) enigmatic creator, unveiled what is arguably its most defining feature: the 21 million BTC supply cap.

加密货币市场可能正处于动荡之中，但今天标志着一个值得暂停和反思的历史时刻。距离比特币 (BTC) 的神秘创造者中本聪 (Satoshi Nakamoto) 公布可以说是其最具决定性的特征：2100 万个 BTC 的供应上限，已经整整 16 年了。

This moment in 2009 introduced the world to a system that would forever change perceptions of money. In the Bitcoin whitepaper, Nakamoto detailed a methodical and finite issuance process, ensuring that Bitcoin's total supply would never exceed 21 million BTC.

2009 年的这个时刻向世界介绍了一个将永远改变人们对金钱的看法的系统。在比特币白皮书中，中本聪详细介绍了一套有条不紊且有限的发行流程，确保比特币的总供应量永远不会超过 2100 万个 BTC。

The coins will be distributed to network participants as rewards for validating transactions, with the issuance halving every four years. This carefully planned progression — 10.5 million coins in the first four years, halving to 5.25 million in the next and so on — is designed to taper off until the final Bitcoin is mined sometime around 2140.

这些代币将作为验证交易的奖励分发给网络参与者，发行量每四年减半。这个精心计划的进程——前四年生产 1050 万枚比特币，接下来减半至 525 万枚，依此类推——旨在逐渐减少，直到 2140 年左右开采出最终的比特币。

Back then, Bitcoin had no price. It existed only as an idea, a digital experiment discussed among a small group of enthusiasts on forums and mailing lists. They engaged in technical discourse, delving into the intricacies of Bitcoin's architecture and marveling at its potential to revolutionize finance.

那时，比特币没有价格。它仅作为一个想法存在，是一小群爱好者在论坛和邮件列表上讨论的数字实验。他们参与技术讨论，深入研究比特币架构的复杂性，并惊叹于它彻底改变金融的潜力。

Now, fast forward to today, and the concept Bitcoin introduced has evolved into a global asset, valued at nearly $2 trillion and woven into the fabric of conversations about finance, technology and economics. Among Bitcoin's most compelling traits is this very supply cap — unchanging and immutable — making it an outlier in a world of unlimited fiat currency printing.

现在，快进到今天，比特币引入的概念已经发展成为一种全球资产，价值近 2 万亿美元，并融入了有关金融、技术和经济的对话结构。比特币最引人注目的特征之一就是这种供应上限——不变且一成不变——使其成为无限印刷法定货币的世界中的异类。

However, there is a divergence between the theoretical supply and the actual circulating amount. As Bitcoin's genesis block was being mined, Satoshi Nakamoto, who disappeared years ago, is believed to have also mined around one million BTC in the early days. These coins have never been moved and are considered lost to time.

但理论供应量与实际流通量存在差距。当比特币的创世块被开采时，多年前失踪的中本聪据信早期也开采了约 100 万个比特币。这些硬币从未被移动过，被认为随着时间的流逝而丢失。

Similarly, countless other early coins remain inaccessible in forgotten wallets or due to lost keys. While the ledger records approximately 19.8 million BTC in circulation today, the functional supply is almost certainly lower.

同样，无数其他早期硬币仍然无法在被遗忘的钱包中或由于丢失钥匙而无法访问。虽然账本记录目前流通的比特币数量约为 1980 万，但功能供应量几乎肯定会较低。
