比特幣的供應上限真的是一成不變的嗎？貝萊德的免責聲明引發了關於加密貨幣未來的爭論

2024年12月17日，全球最大基金管理公司貝萊德引發加密貨幣領域熱議。

BlackRock, the world's largest fund manager, has sparked a heated debate in the cryptocurrency community with a recent statement in an official video, where the company noted that there is no guarantee that the 21 million Bitcoin cap will remain unchanged.

全球最大的基金管理公司貝萊德最近在官方影片中發表聲明，指出無法保證 2,100 萬比特幣上限保持不變，引發了加密貨幣社群的熱議。

This statement has raised concerns about the fundamental value of the world's leading cryptocurrency, causing market volatility and sparking a discussion on its scarcity.

這項聲明引發了人們對全球領先加密貨幣基本價值的擔憂，引發市場波動並引發對其稀缺性的討論。

Technically, the supply limit of Bitcoin could be changed through a hard fork, an update that would require widespread consensus among all network participants. However, as pointed out by Super Testnet, creator of BitVM and Bitcoin expert, such a change would alter the essence of Bitcoin itself:

從技術上講，比特幣的供應限制可以透過硬分叉來改變，這項更新需要所有網路參與者達成廣泛共識。然而，正如 BitVM 的創建者、比特幣專家 Super Testnet 所指出的那樣，這樣的改變將改變比特幣本身的本質：

“The inflation limit is a definition of Bitcoin. Without it, what remains would no longer be Bitcoin.”

「通貨膨脹極限是比特幣的定義。沒有它，剩下的就不再是比特幣了。

This view was echoed by the community, highlighting how the 21 million limit is a core principle of Bitcoin, ensuring its scarcity and value over time.

這一觀點得到了社群的回應，強調 2,100 萬的限制是比特幣的核心原則，隨著時間的推移確保了其稀缺性和價值。

The discussion on the supply limit also has major implications for Bitcoin miners. At present, the block reward is 3.125 BTC, but due to the halving mechanism, this amount will be reduced to 1.625 BTC in 2028.

關於供應限制的討論對比特幣礦工也有重大影響。目前區塊獎勵為3.125 BTC，但由於減半機制，這筆金額將在2028年減少至1.625 BTC。

This economic model raises questions about how to maintain network security as the rewards decrease, unless there is a substantial increase in prices or transaction fees.

這種經濟模型提出如何在獎勵減少時維護網路安全的問題，除非價格或交易費用大幅增加。

The main worry is that a network with lower incentives could become more susceptible to attacks, affecting the trust of investors and users.

主要的擔憂是，激勵較低的網路可能更容易受到攻擊，從而影響投資者和用戶的信任。

Mixed reactions in the community

社區反應不一

BlackRock's statements have elicited contrasting reactions within the crypto community. Some, like Joel Valenzuela, marketing manager of Dashpay, find it unlikely that there will be a change in the supply cap.

貝萊德的聲明在加密貨幣社群內引起了截然不同的反應。 Dashpay 行銷經理 Joel Valenzuela 等一些人認為供應上限不太可能改變。

Others, such as Antiprosynthesis, an Ethereum programmer, have suggested that BlackRock may understand Bitcoin better than its own proponents.

其他人，例如以太坊程式設計師 Antiprosynthesis 則表示，貝萊德可能比其支持者更了解比特幣。

This contrast in opinions has led to increased market volatility, with Bitcoin prices experiencing significant swings following the announcement.

這種觀點的比較導致市場波動加劇，比特幣價格在公告發布後大幅波動。

The discussion on the supply limit also brings to mind the Blocksize Wars of 2016-2017, a period when the Bitcoin community successfully resisted attempts to increase the block size.

關於供應限制的討論也讓人想起 2016-2017 年的區塊大小戰爭，這段時期比特幣社群成功抵制了增加區塊大小的嘗試。

Despite 95% of the miners being in favor of the change, the proposal was not accepted, showcasing the strength of consensus in the Bitcoin network.

儘管 95% 的礦工支持這項改變，但該提議並未被接受，這顯示了比特幣網路共識的力量。

This historical resistance highlights the difficulty in making substantial changes to Bitcoin without complete support from the community.

這種歷史阻力凸顯了在沒有社群完全支持的情況下對比特幣進行實質改變的困難。

Future implications

未來的影響

According to Super Testnet, any effort to change the Bitcoin supply limit would require a broad consensus among all stakeholders, including developers, miners, node operators, and investors.

根據超級測試網的說法，任何改變比特幣供應限制的努力都需要所有利害關係人（包括開發人員、礦工、節點營運商和投資者）達成廣泛共識。

This decentralized governance system is designed to protect Bitcoin from external influences, even from large firms like BlackRock.

這種去中心化的治理系統旨在保護比特幣免受外部影響，甚至來自貝萊德等大公司的影響。

However, the discussion prompted by BlackRock's disclaimer also points to a wider issue: the increasing role of traditional institutions in the world of cryptocurrencies.

然而，貝萊德的免責聲明引發的討論也指出了一個更廣泛的問題：傳統機構在加密貨幣世界中的作用日益增強。

While this influence may lead to greater adoption on one level, it also raises questions about the future of decentralization and the autonomy of blockchain networks.

雖然這種影響可能會在一定程度上導致更多的採用，但它也引發了關於去中心化和區塊鏈網路自治的未來的問題。
