Bitget遭3.51亿美元黑客攻击，Circle和Tether冻结钱包；加密货币巨头刚刚承认其存在中心化机构

去中心化金融：除非Circle和Tether按下冻结键

除了当Circle和Tether决定按下“冻结”按钮时，去中心化金融（DeFi）才显得名副其实。而就在刚刚，他们这样做了。仅仅在几小时内。

改变一切的公告

2026年9月，Bitget遭受黑客攻击，3.51亿美元被盗。数小时内，Circle和Tether将黑客的钱包列入黑名单。31.8万美元的USDT和USDC被瞬间冻结。

加密货币行业称此为胜利：反应迅速，行动协调，系统运作良好。

但事实真相是：两家公司决定了哪些钱包可以移动资金，而资金流动随即停止。这不是去中心化，这是拥有冻结权限的中心化权威。而这周，他们使用了它。

去中心化本应意味着什么

加密货币的全部前提建立在这样一个理念之上：没有任何单一实体控制网络。没有银行能冻结你的账户，没有政府能阻止你的交易，没有公司能决定你的资金不可动用。协议运行，交易执行，无人能阻。这就是承诺，白皮书的内容，也是吸引数百万厌倦了被告知如何支配自己金钱的人进入加密世界的故事。

然而，Circle和Tether刚刚证明，这个承诺带有注脚。注脚写着：“除非我们另有决定。”

鲜为人知的技术现实

stablecoins are not decentralized assets, they have never been. USDT and USDC are IOUs issued by private companies. Tether releases USDT and Circle releases USDC. Both companies maintain blacklists of addresses that cannot send or receive their tokens.

This is not a loophole, but a feature required by the regulatory framework. Circle and Tether operate under regulatory frameworks that require them to be able to freeze funds linked to illegal activities, violations of sanctions or court orders. In other words: The world's most widely used "cryptocurrency" assets have a centralized control mechanism built into it from the beginning.

The Bitget hacking incident has made this clear to those who have not paid attention to this fact. As $351 million flows through wallets controlled by Circle and Tether, these companies can decide in real time which addresses are blacklisted. They don't need a court order for an initial freeze or a blockchain consensus. They just need to make a decision and the flow of funds stops.

The irony is structural, not accidental.

What's really interesting is that the centralized freezing capabilities used by Circle and Tether this week are not mistakes or compromises, but the key to enabling stablecoins to function at institutional scale. Regulators need it, banks need it, and companies need it. If you want to integrate stablecoins into traditional finance, you must have the ability to freeze funds linked to crime, sanctions, or court orders. There is no other way.

Therefore, the cryptocurrency assets with the highest adoption rates are also the most centralized assets in design. The story of adoption is in direct conflict with the story of decentralization, and the story of adoption is winning.

USDC and USDT process US$46 trillion in transactions each year. They are critical infrastructure for global commerce. They are reliable because they are trusted by regulatory entities; they can be trusted because they have centralized control. The more popular mainstream cryptocurrency becomes, the more these controls are needed; the more these controls are needed, the less they are what they originally claim to be.

Who really controls your cryptocurrency

We need to understand exactly what "control" means in this context. If your positions are Bitcoin or Ethereum and are stored in a self-managed wallet, Circle and Tether cannot freeze them. The protocol is truly decentralized, and no one has a freeze key for native cryptographic assets.

However, if your position falls into the following circumstances:

• USDT or USDC in any wallet
• Any exchange account
• Any escrow product, including ETF
• Any wrapping or bridging token routed through regulated infrastructure

Then, Someone (or people) holds the freeze button in their hands. The way most people actually hold cryptocurrencies in 2026 means that most crypto assets can be frozen at a practical level, not just in theory.

In the Bitget hack incident, US$318,000 was immediately frozen, and the remaining US$351 million stayed on Ethereum. Because Ethereum is truly decentralized, it cannot be frozen. Hackers know this well, which is why most of the money is in ETH. Hackers have a deeper understanding of architecture than most users.

Decentralized maximalists 'silence

Whenever stablecoin issuers freeze wallets linked to apparent criminal activity, the crypto community responds the same way: "It's okay. They froze criminals 'funds and the system worked as expected."

On the surface, this is true. The $351 million hacking case is distressing, but freezing funds accessible to hackers is a good thing. But this argument is too broad. If Circle and Tether can freeze a hacker's wallet within hours because of their decision, they can freeze your wallet within hours. As long as someone decides to do it.

This ability is not limited to criminals. It is a universally applicable power, first applied to criminals because it is the least controversial use scenario. The question is not whether the power was used correctly this week, but who has it, under what conditions and with what supervision. The answer for 2026 is: two private companies, with limited external accountability based on their own terms of service. This is not a decentralized system, this is a different kind of centralized system that markets better.

What does this mean for cryptocurrency identity

Bitget黑客事件及随后的冻结揭示了加密货币身份中长期存在的分歧。如今共存着两个版本的加密货币：

版本1：作为去中心化基础设施的加密货币。比特币、自我托管的以太坊。真正的无需许可、抗审查，无人拥有冻结键。这个版本存在且有效，但它更难使用，未与传统金融集成，仅由少数真正的加密参与者使用。

版本2：作为受监管金融基础设施的加密货币。稳定币、交易所账户、ETF、托管产品。这是大多数人实际使用的版本。它快速、便捷，与传统系统集成，但也内置了中心控制、冻结能力和监管合规性。

过去三年中，加密货币的大部分采用增长发生在版本2中。5.59亿持有加密货币的用户，大多将资产存放在可被冻结的系统中。版本1是加密货币声称自己是的样子，版本2是它实际成为的样子。两者都是真实的，混淆二者之处正是身份危机的根源。

一个正当的问题

这并不意味着加密货币失败了，而是意味着加密货币朝着特定方向成熟，而这个方向涉及比原始愿景更多的中心化。这究竟是好是坏，取决于你认为加密货币是用来做什么的。

If you believe that cryptocurrencies are designed to build truly decentralized alternatives to traditional finance, then Tether and Circle's ability to freeze is a betrayal of the founding premise. If you think that cryptocurrencies are designed to build faster, more convenient, and more global financial infrastructure, then the same freezing ability is a feature that makes the infrastructure credible enough for mainstream use.

Both positions are logically consistent. The problem is that the cryptocurrency industry has never honestly stated which one they are building. They promoted version 1, but built version 2. Events like this week's Bitget freeze make this gap impossible to ignore.

What should have been said this week

The correct description of what happened this week should not be "the system is working well", but rather: "Two companies exercised central control over the decentralized network to stop crime." In this particular case, this was the right decision. Let us have an honest dialogue on the meaning of this power, its holders, its conditions for use, and future governance."

This conversation did not happen. Instead, the industry celebrates the freeze as evidence that cryptocurrencies can respond to crime, without delving into the nature of the system implied by the freeze capabilities. The key question is: Should Circle and Tether have freezing capabilities? Under what governance structure? What kind of supervision is there? How to prevent abuse? What are the remedies for wrongful freezing? These questions are not abstract theories; they determine whether "decentralized finance" is a descriptive term or a marketing slogan.

Conclusion

Bitget的3.51亿美元黑客事件是一个安全故事。Circle和Tether的快速冻结是一个治理故事。治理故事比安全故事更重要，因为它揭示了2026年加密货币的真实面貌，这是单纯的安全故事无法告诉你的。加密货币在其对用户最重要的地方正日益中心化。这不是丑闻，而是采用的后果。它值得一次诚实的对话，而非伪装成胜利的庆祝。

冻结键确实存在，本周它发挥了作用。谁控制它，以及在什么规则下控制，是加密货币尚未回答的问题。
