以太坊进入中年危机,四年销毁73亿美元,为何代币仍旧通胀不止

引言

以太坊作为全球领先的智能合约平台,自POW转POS以来,通过 EIP-1559 引入烧毁机制,试图实现通缩目标。

然而,截至 2025 年 4 月 13 日,研究显示其供应量仍以年均 0.805% 增长,增加了 3,477,830.85 ETH,尽管烧毁了 4,581,986.52 ETH。本报告从研究视角分析这一现象,探讨历史背景、当前动态、影响因素及未来展望。

历史背景

伦敦硬分叉引入 EIP-1559,改变了交易费用管理方式。之前,所有交易费用作为矿工奖励;新机制下,基础费用被烧毁,剩余“小费”分配给验证者(合并前为矿工)。此机制旨在对抗新 ETH 发行的通胀效应,最终使 ETH 成为通缩资产。

2022 年 9 月的合并将以太坊从 PoW 转为 PoS,显著降低发行率。合并前,矿工每日获得约 13,000 ETH;合并后,基于约 1,400 万 ETH 的质押量,发行量降至约 1,700 ETH/日。这一变化为实现通缩奠定了基础,但烧毁机制的实际效果依赖网络活动和费用水平。


当前供应动态


销毁

自2021年8月以来,已烧毁价值73亿美元的以太坊(ETH)。

截至 2025 年 4 月 13 日,以太坊流通供应量约为 120,690,000 ETH,年增长率为 0.51%。自伦敦硬分叉以来,烧毁了 4,581,986.52 ETH,总价值约 73 亿美元(基于历史 ETH 价格)。然而,净供应量增加了 3,477,830.85 ETH,表明发行量超过烧毁量。

对比比特币,相同时期(三年八个月)其年均通胀率为 1.517%,尽管比特币有固定 2,100 万枚的上限,而以太坊理论上供应无限。


影响因素分析

以下因素影响烧毁和发行之间的平衡:

网络活动和交易费用:

  • 烧毁率与交易量和费用直接相关。高活动期(如 NFT 热潮或 DeFi 激增)可能导致临时通缩。2024 年 Dencun 升级通过引入 proto-danksharding 降低了二层交易费用,改善用户体验,但也减少了烧毁量。
  • 例如,Dencun 使二层解决方案(如 Optimism、Arbitrum)交易成本降低,间接减少主链烧毁。


发行率:

  • 合并后,发行率基于质押奖励,约每日 1,700 ETH,年发行量约 620,500 ETH(假设质押参与稳定)。尽管较合并前(13,000 ETH/日)大幅减少,但当前烧毁率在低活动期仍不足以抵消。


主要烧毁贡献者:

数据显示,烧毁来源主要包括:

销毁


这些平台驱动大量交易,但活动水平受市场条件影响,如 NFT 趋势和 DeFi 使用率波动。

市场条件:

  • 高活动期可能实现临时通缩,低活动期(如 2024 年 Q2,新增 75,301 ETH)则转为通胀。2024 年 Q2 数据显示,发行量 228,543 ETH,烧毁量 107,725 ETH,净增 120,818 ETH。


持续通胀原因分析

以太坊当前供应动态未来可能受以下因素影响:


技术演进中的"预期陷阱"

EIP-1559机制设计的局限性

尽管燃烧机制通过销毁基础费用创造了价值捕获新范式,但其效能受制于网络活跃度的非线性波动。数据显示,2024年Dencun升级后,Layer2交易占比突破83%,导致主网日均Gas费收入暴跌72%

分片技术的实施困境

原计划2025年Q1完成的Pectra分片升级因ZK-Rollup兼容性问题推迟,导致TPS仍停留在15-45区间,无法支撑高频交易场景


生态竞争中的"价值耗散"

多链生态的价值分流

Solana凭借9000 TPS与0.0001美元交易成本,在2024年夺取38%的公链市场份额,其日活用户达200万,是以太坊主网的5.6倍

DeFi与NFT的结构性衰退

以太坊链上NFT销售额从2023年峰值12.3亿美元/月跌至2025年的1.25亿美元,而Uniswap v4全面转向L2后,主网DEX交易量占比不足9%。更严峻的是,RWA(现实世界资产)赛道中,贝莱德等机构选择Polygon发行代币化基金,使以太坊错失万亿级市场入口


经济模型的反身性悖论

质押机制的激励失衡

合并后设计的3.2%质押收益率,在美联储基准利率达5.25%的宏观环境下失去吸引力,验证节点数量从349.5万降至340万,质押率滑落至27%

燃烧机制的非对称效应

数据建模显示,ETH通缩阈值需满足:燃烧量 > 发行量(约1600 ETH/日)。但在市场低迷期,网络活跃地址数降至36万/日,仅能维持日均800 ETH的销毁量


监管环境的结构性压制

证券化认定的阴影

SEC将75%的ERC-20代币纳入证券监管,并禁止ETH ETF参与质押,直接导致机构资金流入量同比减少22%。相比之下,比特币凭借"数字黄金"的清晰定位,吸引300亿美元ETF资金流入,监管套利空间差异加剧ETH/BTC汇率跌至0.02的历史低位。

合规成本的转嫁效应

为满足KYC/AML要求,账户抽象等合规改造使智能合约Gas消耗增加27%,进一步抑制网络活跃度。


结语:区块链的中年危机

以太坊的通缩困境本质上是技术理想主义与商业现实主义的碰撞缩影。当ETH市值占比维持在17.5%的历史低位,其反映的不仅是货币政策的失衡,更是整个行业从"概念验证"向"价值创造"转型的阵痛。未来的破局之路,或许不在于对通缩模型的机械追求,而在于构建一个兼容效率、公平与监管可持续性的新范式。正如中本聪创造比特币时未曾预料ETF狂潮,以太坊的价值发现也需要跳出既有框架,在技术理想与市场现实之间找到动态平衡点。

77 Bloody Codes: When the '$5 Wrench' Shatters the Privacy Myth of France's Crypto Elite

**Summary** In the first half of 2026, France recorded 77 violent crimes—including kidnappings, illegal confinement, and extortion—targeting cryptocurrency holders, a 71% increase over the 45 cases in all of 2025. This equates to an attack every 2.3 days, making France a global hotspot for so-called "wrench attacks," where criminals use physical violence to coerce victims into surrendering crypto assets. High-profile cases include the 2025 kidnapping of Ledger co-founder David Balland, who was shown with a severed finger in a ransom video, and an attempted kidnapping of the family of Paymium's CEO in Paris. Prosecutors note these are not isolated incidents but part of structured criminal networks, sometimes involving minors. Several factors contribute to France's vulnerability: a large holder base (approx. 7.3 million people), the presence of major crypto firms and executives, a culture of public disclosure among enthusiasts, and potential data leaks. The trend is spreading across Europe, which now accounts for over 40% of such global attacks. Research indicates a correlation between Bitcoin price surges and increased wrench attacks. In response, French Interior Minister Laurent Nuñez announced a three-pillar action plan focusing on enhanced intelligence sharing, deeper cooperation with the industry association Adan, and improved operational and cross-border coordination. Authorities have made over 200 arrests in the past year. Security experts warn that digital asset safety now extends to the physical world. They advise holders to use hardware wallets, avoid disclosing holdings on social media, enable multi-factor authentication, and report suspicious activity. The situation underscores the urgent need for the crypto community to shift from a "show-off" culture to one of discretion as physical security becomes paramount.

Both OpenAI and Anthropic are 'Developing Their Own Chips' — Beyond Cost, the Control Over Computing Power is Paramount

OpenAI and Anthropic are both advancing plans to develop custom AI chips, driven by the need to control computing power and reduce costs. According to reports, Anthropic is in early-stage development of its own chips and in talks with Samsung for manufacturing, while OpenAI is collaborating with Broadcom and TSMC, aiming to deploy its first inference chip by late 2026. The primary motivation extends beyond just lowering expenses. For these large model companies, chips are core production assets. By designing specialized hardware (ASICs) tailored to their specific model architectures—OpenAI's being more sparse and Anthropic's more dense—they aim to achieve deeper software-hardware co-design. This synergy can significantly improve inference speed, energy efficiency, and overall unit economics, offering advantages that off-the-shelf GPUs cannot. This move does not signify an immediate replacement for suppliers like Nvidia. The process from design to deployment takes 18-24 months, and Nvidia's GPU ecosystem remains deeply entrenched. Instead, custom chips provide a strategic alternative and negotiating leverage, allowing companies to use them for specific, high-volume workloads like inference while still relying on external GPUs and TPUs for other tasks. The trend reflects a broader industry shift where AI competition is evolving from pure algorithmic prowess to integrated control over the entire software-hardware stack. Companies like Google, Amazon, Meta, and Microsoft are already on this path. For foundries like Samsung, securing orders from AI leaders like Anthropic represents a significant opportunity to expand its footprint in the advanced semiconductor market for AI. Ultimately, the race for "computing sovereignty" is now a central battleground for major AI players.
