比特币和以太坊存储的数据非常少；但 Arweave、Filecoin 等其他区块链专为下一代数据存储而构建。

随着区块链技术的最新进展，人们想知道这项技术可以解决哪些现实问题。区块链似乎准备颠覆的一个领域是数据存储。

区块链上可以存储多少数据？存储在区块链上的数据从兆字节 (MB) 到拍字节 (PB) 不等，具体取决于区块链。最流行的区块链：比特币和以太坊，存储的数据非常少。但 Arweave、Filecoin、Storj 和 Sia 等其他区块链是专为下一代数据存储而构建。

在这篇文章中，我们将探讨如何使用区块链来存储数据以及它们必须拥有的数据容量。

第一个区块链：比特币和以太坊数据存储

比特币数据存储

比特币区块链经常因其安全性和透明度而受到称赞。比特币网络上发生的每一笔交易都不可篡改地记录在区块链上。这意味着你可以回头查看在比特币网络上进行过的每一笔交易。

但是比特币适合数据存储吗？虽然比特币忠实地记录了发生在其上的所有交易的公开分类账，但这需要相对较少的存储量。

实际上，比特币区块链在数据存储方面效率不高。这是因为记录在区块链上的每一笔交易都必须经过网络验证才能添加到链上。这个验证过程需要大量的计算能力和处理时间。因此，比特币区块链目前每秒只能存储大约四笔交易。

虽然有些人在比特币上隐藏了秘密信息 [1]，但它不是用于存储重要数据的地方。

截至 2022 年 12 月，比特币区块链上存储了 440 GB 的数据。为了比较起见，Dropbox 为其初始个人帐户提供了 2 GB 的存储空间。

以太坊数据存储

以太坊区块链是数字货币、全球支付和应用程序的家园。该社区已经建立了蓬勃发展的数字经济，为创作者提供了大胆的在线赚钱新方式，并继续走在计算机科学创新的前沿。

以太坊还支持数据存储。与比特币不同，以太坊对其区块大小没有限制。这意味着以太坊区块链理论上可以处理无限数量的交易。

但是，与比特币一样，它不是存储数据的好地方。高昂的 gas（交易）费用和高昂的存储成本使其对大多数用户来说不切实际。2022 年 2 月，在以太坊上存储 500KB 的数据就需要 20,000 美元 [2]。

以太坊的主要目的是记录金融交易和所有权变更——而不是数据存储。

截至 2022 年 12 月，以太坊区块链的大小为 1055 GB。同样，这比前面提到的 Dropbox 上的个人帐户空间要少得多。

总而言之，比特币和以太坊不适合大量数据存储。但是其他可用的区块链选项更适合数据存储。让我们看看一些专注于存储的区块链以及它们可以容纳多少。

其他区块链上的数据存储

随着比特币和以太坊的技术突破，开发人员将目光转向使用区块链技术存储大量数据只是时间问题。

他们为什么不呢？必须有一个分散的、低成本的、不可变的数据存储市场，对吧？

到 2010 年代中期，人们开始投入大量精力创建区块链，使大量数据的存储具有成本效益。这些努力产生的主要区块链是 Arweave、Filecoin、Storj 和 Siacoin。

总存储容量（这些区块链可以容纳的数量）达 25 亿 GB ，或换句话说，是当今互联网大小的几倍。同样，每个人都可以从小到大上传文件。

让我们来看看这些区块链，看看每个区块链上可以存储多少数据。

你可以在这些区块链上存储多少？

存储空间的主要参与者是 Filecoin 和 Arweave。Filecoin（如 Siacoin 和 Storj）基于类似于亚马逊或谷歌提供的每月订阅费，而 Arweave 提供一次性的永久存储费用。

让我们看看这两个选项，看看它们在存储方面提供了什么。

Filecoin

Filecoin 是一个去中心化的存储网络，用户向矿工付费以将他们的文件存储在世界各地的服务器和节点上。Filecoin 目前是最大的去中心化网络。

Filecoin 的主干是 IPFS（InterPlanetary File System），它是一种点对点的分布式文件系统，允许用户以去中心化的方式存储和共享数据。Filecoin 建立在 IPFS 之上，并将其用作数据存储层。

将文件上传到 Filecoin 的付费方式是通过类似于亚马逊或谷歌的订阅服务。最终，Filecoin 旨在与 Amazon S3 和 Microsoft Azure 等中心化存储提供商竞争，并且很可能必须成为低成本的存储生产商才能生存。

Filecoin 的容量是多少？Filecoin Network 已达到 18 exbibytes (EiB) 的数据存储能力。

你可以将多大的文件上传到 Filecoin？每个文件 64GiB 或 68,182,605,824 字节。

如果你的数据集太大怎么办？你可以对超过 64 GiB 的数据集进行离线存储传输。

Arweave 开发了一个区块链来提供永久存储

Arweave

Arweave 是一种去中心化存储协议，它以可通过一次付费，持续和永久的存储数据，允许用户和开发人员真正永久地存储数据——这是第一次。

Arweave 是一个去中心化网络，允许任何人永久和安全地存储数据。它旨在抗审查，并允许用户上传任何大小的文件。

Arweave 有一种新颖的收费模式，该模式为存储成本提供永久资金。这意味着用户只需要支付一次性费用就可以将数据永久存储在 Arweave 上。

Arweave 已经在其区块链上存储了超过 110 TB 的数据，使其成为数据存储方面最大的区块链。你可以在此处 [3]查看所有 Arweave 上传统计数据。

如果你正在寻找更适合长期数据存储的区块链选项，Arweave 是一个不错的选择。

Arweave 上可以存储多少数据？Arweave 对可以存储的数据量没有限制。

Arweave 上文件的大小限制是多少？Arweave 上的文件没有大小限制，但您可能会受到用于将文件放到 Arweave 上的工具或应用程序的限制。

我如何使用 Arweave？有许多应用程序正在 Arweave 上构建，以帮助人们将他们的文件放到网络上。查看 ardrive.io 或 arweave.net 寻求帮助。

The Impossible Trilemma Is Basically a Pseudo-Problem

The article argues that the core limitation of blockchain technology is not the scalability trilemma, but its fundamental lack of privacy, which acts as a barrier to institutional capital. It defines blockchain as a slow, expensive, shared computer whose primary value is "permissionlessness" (no administrator) and verifiable trust. While this is ideal for native financial assets like stable币, which now process trillions, two critical flaws remain for mainstream adoption: regulatory legitimacy and a default transparency that leaks all financial activity. The author contends that transparency is not a feature but a tax, quantified through MEV extraction, making the public ledger unusable for serious institutions. However, modern cryptography, specifically zero-knowledge proofs, now offers a solution: "provable privacy." This allows users to prove compliance (e.g., solvency, KYC) without revealing underlying data. This fusion of privacy and auditability resolves the transparency-compliant privacy-compliance dichotomy, enabling a purely upgraded system where transactions are verified but not broadcasted. Closing these flaws is presented as the essential bridge to onboard the next wave of trillions in capital.

The "Impossible Triad" Is Fundamentally a Pseudo-Problem

The article argues that blockchain's fundamental limitation is not the scalability trilemma (decentralization, scalability, security), which has been largely solved, but the lack of **privacy** and, until recently, clear **legitimacy**. Blockchain is described as a slow, expensive, globally shared computer whose core value is censorship resistance and verifiability. While ideal for native digital assets like money (e.g., stablecoins), its default transparency acts as a **tax**, exposing all transactions and enabling MEV extraction, which deters serious institutional capital. Simultaneously, its permissionless nature created regulatory ambiguity. The piece contends that **privacy** is the missing critical feature. It rejects the false choice between total transparency and complete anonymity. Modern cryptography (like zero-knowledge proofs) enables **compliant privacy**: users can prove facts (solvency, KYC status, compliance) without revealing the underlying sensitive data (specific holdings, identities). This preserves auditability for regulators and eliminates the leak of financial information. With recent regulatory progress (e.g., the GENIUS Act) addressing legitimacy, adding default, provably compliant privacy becomes a pure upgrade. It transforms blockchain from a costly, public ledger into a confidential settlement layer, finally bridging the gap to mainstream institutional and individual adoption of on-chain finance.

Optical Chips: Collective Capacity Expansion

The global optical chip industry is experiencing a massive wave of expansion driven by surging AI data center demand. Major players across the US, Japan, Europe, and China are aggressively investing to ramp up production capacity. In the US, Coherent is expanding its 6-inch Indium Phosphide (InP) semiconductor fab in Texas, supported by CHIPS Act funding and a $2 billion strategic investment from NVIDIA. Lumentum is building a new factory for InP optical devices, and Nokia is scaling its advanced photonic chip packaging and testing capabilities. NVIDIA's investments aim to secure future supply of critical lasers and optical interconnect products for AI infrastructure. Japan's JX Advanced Metals, a leading InP substrate supplier, plans a multi-billion yen investment to increase its capacity 7-10 times, strengthening its grip on the crucial upstream materials market. In Europe, IQE and Tower Semiconductor settled a patent dispute and signed a multi-year InP epitaxial wafer supply agreement, highlighting that next-generation silicon photonics platforms will integrate high-performance InP components. STMicroelectronics and Sivers Semiconductors are also expanding silicon photonics production and partnerships. China is rapidly building out its domestic supply chain. Dongshan Precision's subsidiary, Source Photonics, announced a $12 billion project to expand optical chip and module production. Companies like Sanan Optoelectronics and Yunnan Germanium are scaling up InP chip manufacturing and substrate production, moving towards vertical integration from materials to modules. While debate continues around the exact future architecture—whether CPO (Co-Packaged Optics), NPO, or pluggables will dominate—analysts like Morgan Stanley argue the underlying driver is unchangeable: the explosive growth in bandwidth demand. This will inevitably increase the volume of optical engines, lasers, and related content per GPU, regardless of the final technical path. The competition for "more light" in the AI era has intensified into a global, full-chain capacity race.

Stablecoins Finally Find Real Yield: An In-Depth Look at On-Chain Reinsurance Re | A Conversation with Re Founder Karan Saroya

Stablecoin Real Yield Found: A Deep Dive into On-Chain Reinsurance with Re's Karan Saroya As stablecoin supply exceeds $170 billion, the search for sustainable, non-speculative yield intensifies. Re, an on-chain reinsurance platform, provides an answer: connecting stablecoin capital to the trillion-dollar traditional reinsurance market. Re operates as a regulated reinsurer, accepting stablecoin deposits as collateral to back US insurance companies. These insurers pay premiums, generating yield that flows back to on-chain depositors. Currently supporting 35 insurers and underwriting $500 million, Re projects scaling to over $1 billion soon. Key insights from a Bankless podcast with founder Karan Saroya and investor Avichal of Electric Capital: 1. **Uncorrelated, Real-World Yield:** Re offers stablecoin holders access to reinsurance returns (targeting 12-14%+), an asset class entirely separate from crypto or equity markets. 2. **Operational Efficiency via Smart Contracts:** Re replaces traditional, labor-intensive capital fundraising with smart contracts, allowing a ~12-person team to compete with industry giants. 3. **Regulatory Leverage:** For every $1 of collateral, regulations allow backing $5-7 in written premiums. This leverage amplifies returns from the underlying risk-free rate. 4. **DeFi Integration:** Depositors receive receipt tokens, which can be used in protocols like Morpho for "looping," potentially pushing yields to 18-20%+. 5. **The "DeFi Mullet" Model:** A compliant front-end (regulated reinsurer) paired with a decentralized back-end (smart contracts, DeFi capital markets). 6. **RE Governance Token:** Modeled on Lloyd's of London, the token governs the central capital pool's allocation, counterparty acceptance, and parameters. 7. **Real Economic Impact:** Capital funds real-world productivity (factories, clinics, businesses) via insurance, moving beyond crypto's internal loops. The discussion highlights a pivotal moment: DeFi's supply-side infrastructure is now met by real demand for productive yield, potentially kickstarting a flywheel where vast on-chain stablecoin capital seeks these real-world returns.

1996 or 1999? Walsh's First Test is 'How to View AI'

"1996 or 1999? Wall's First Big Test Is 'How to View AI'" Federal Reserve Chairman Wall's initial challenge is not whether to raise or cut rates, but a more fundamental judgment: what kind of boom is the current AI boom? This will determine the Fed's policy path and define his legacy. Economics is split between two opposing views, according to reporter Nick Timiraos. One sees imminent productivity gains that will increase supply and cool inflation, allowing the Fed to hold steady. The other argues that while productivity benefits are distant, demand shocks are here now, and waiting for data confirmation risks missing the intervention window, forcing sharper rate hikes later. Wall has signaled a leaning toward the first view, echoing 1996-era Alan Greenspan, who embraced strong, productivity-driven growth without fear of inflation. However, Wall faces a different macro environment than Greenspan did, with tariff pressures, expanding fiscal deficits, and diminishing globalization benefits, which could force more significant inflation pressures even if AI benefits materialize. Wall's logic, expressed before taking office, is that AI-driven productivity gains won't show in official data for years. If the Fed waits for confirmation, it might mistakenly tighten policy and choke off the very growth that could suppress inflation. This argues for using forward-looking narratives over lagging data. Chicago Fed President Austan Goolsbee presents a key counter-argument. He distinguishes between expected and unexpected productivity booms. A widely anticipated boom, like the current AI wave, can cause people to spend future wealth gains in advance, overheating the economy before productivity actually rises, thus requiring preemptive rate hikes. He cites rising costs for AI data centers as evidence of such overheating. Fed Governor Christopher Waller offers a rebuttal to Goolsbee, noting the "expected spending" mechanism only works if people can borrow against future income, which many households cannot do due to borrowing constraints. Wall also faces a paradox related to his desire to reduce the Fed's use of "forward guidance" (pre-announcing policy moves). This practice was established in 1999 when Greenspan began signaling hikes to avoid market shocks. If the economy follows a less optimistic path, Wall may be forced to choose between using the guidance he wants to abolish or risking market volatility by staying silent. The ultimate question defining Wall's first major test remains: Is this 1996 or 1999?
