坎昆升级预期下,模块化区块链概念被市场一致认为是2024年投资主旋律之一。

原文作者:Nancy,PANews

近期,随着 Celestia 价格持续走高,数据可用性(DA)层成为热门加密叙事。特别是以太坊坎昆即将升级预期下,模块化区块链概念备受关注,也被市场一致认为是 2024 年投资主旋律之一。本文 PANews 盘点了 7 个 DA 赛道的潜力项目,它们采取了不同类型的数据处理解决方案,在可拓展性、去中心化和安全性等方面各具优势。

Celestia(TIA)

Celestia 是第一个专注于数据可用性的模块化区块链项目,旨在通过提供可插拔的共识网络来简化区块链部署,让任何人都可以最小成本快速部署去中心化的区块链。Celestia 共完成了两轮融资,包括 Binance Labs 领投的 150 万美元种子轮融资,以及 Polychain 和 Bain Capital 领投的 5500 万美元 A/B 轮融资。

TIA 是 Celestia 的原生代币,用于 Gas 费用、节点质押和治理等用途,因 2023 年 9 月开启的创世空投备受关注。近期,包括模块化区块链项目 Dymension、layer 2 项目 Hypr Network 和 Cosmos 生态可扩展性协议 Saga 等均已有不少项目开始面向 Celestia 进行空投。Mintscan 数据显示,截至 1 月 16 日,Celestia 的总交易笔数超 984.9 万笔,质押原生 TIA 代币的 APR 达 16.07% 。

CoinGecko 数据显示,截至 1 月 16 日,TIA 的代币价格约为 18.85 美元,过去 30 天涨幅达 47.7% ,流通市值超 29.6 亿美元。

EigenDA(尚未发币)

EigenDA 是再质押协议 EigenLayer 开发的数据可用性中间件产品,旨在降低以太坊 Layer 2 Rollup 数据存储成本。EigenDA 也是首个在 EigenLayer 上启动的主动验证服务(AVS),再质押者将可将质押权委托给为 EigenDA 执行验证任务的节点运营商从而换取服务支付,且 Rollup 能够将数据发布到 EigenDA 以获得更低的交易成本以及更高的交易吞吐量和安全性。EigenLayer 也曾完成两轮融资,分别是 Polychain Capital 和 Ethereal Ventures 领投的 1450 万美元种子轮融资,以及 Blockchain Capital 领投的 5000 万美元 A 轮融资。

虽然 EigenLayer 尚未确认是否会发行代币,但市场对其空投预期非常高。而根据 EigenLayer 的早期规划,其将分为三个阶段启动。目前,EigenLayer 已启动 EigenLayer 和 EigenDA 第二阶段测试网并预计将于 2024 年上半年上线主网,第三阶段则将于 2024 年进入测试网和主网。

Avail(尚未发币)

Avail 是 Polygon Labs 于 2020 年年底启动的数据可用性层的模块化区块链解决方案,于去年 3 月分拆成独立实体,旨在通过采用轻客户端、数据可用性采样、纠删码和 KZG 承诺和纠删码等技术来实现更大的可扩展性并解决数据可用性信任问题。此前,Polygon 联合创始人 Anurag Arjun 和研究负责人 Prabal Banerjee 均在离职后加入了 Avail。

2023 年 11 月,Avail 宣布启动 Clash of Nodes 激励测试网,并预计将于 2024 年初推出主网。

NEAR DA(NEAR)

EAR DA 是 NEAR 基金会于 2023 年 11 月宣布推出的 DA 层解決方案,旨在帮助以太坊 rollup 构建者简化其网络并降低成本,在 NEAR DA 的数据发布成本比在以太坊上低 8000 倍,首批用户包括 StarkNet 的 Madara、Caldera、Fluent、Vistara、Dymension RollApps 和 Movement Labs。

CoinGecko 数据显示,截至 1 月 16 日,NEAR 的代币价格约为 3.24 美元,过去 30 天涨幅约 35.5% ,流通市值超 32.94 亿美元。

StarkEx(STRK,未上线)

StarkEx 是 StarkWare 团队研发的以太坊 Layer 2 扩容解决方案,且也提供多种数据可用性模式:Rollup、Validium 和 Volition。其中,Validium 作为 StarkEx 的链下 DA 方案,数据的安全性由数据可用委员会(DAC)来维护。

zkPorter(尚未发币)

zkPorter 是以太坊扩容方案 zkSync 推出的针对去中心化优化的链下数据可用性解决方案,通过结合 zkRollup 和分片思想的混合方法来处理数据可用性。zkPorter 引入了可选的验证器机制,由 zkSync 代币持有者质押代币后来验证和签署区块。虽然 zkPorter 的产品进展在很长时间里一直未向外界披露,但从 zkSync 上的 Layer 3 应用链 GRVT 计划在今年Q1上线主网,且该项目是在 zkPorter 上存储数据来看,zkPorter 被外界猜测或将在此之前启动。

Covalent EWM(CQT)

区块链数据查询服务平台 Covalent 可以标准化来自多个区块链的数据,其统一 API 允许开发者在支持的网络中重复使用查询,解决了区块链数据难以获取的问题。2023 年 11 月,Covalent 推出了长期资料可用性层服务 Ethereum Wayback Machine (EWM,以太坊回溯机),以永久保存被以太坊丢弃的 Layer 2 状态数据。截至 2023 年 12 月,Covalent 共支持 210 多条区块链,计划在 2024 年底时支持 1000 多条区块链。

而据不久前 Messari 发布 Covalent 数据可用性报告指出,Covalent 拥有数十亿条数据,是目前最适合为需要通用、广泛适用数据的应用提供服务。

CoinGecko 数据显示,截至 1 月 16 日,CQT 的代币价格约为 0.23 美元,过去 30 天涨幅约 9.9% ,流通市值超 1.47 亿美元。

Podcast Notes: Hyperliquid Has Become the Top Interest Point for Traditional Hedge Funds

Empire Podcast hosts Jason Yanowitz and Santiago Santos discuss the surging institutional interest in Hyperliquid, a decentralized perpetual exchange, marking the highest level of engagement from traditional hedge fund managers since Paul Tudor Jones endorsed Bitcoin in 2020. The primary driver is the demand for weekend trading of commodities like oil, especially during geopolitical tensions such as the Iran conflict, as Hyperliquid provides the only active price discovery venue when traditional markets are closed. Trade XYZ, a front-end on Hyperliquid, has seen significant growth, with weekend oil price predictions having a median error of only 50 basis points. Santos predicts commodity trading volume on Hyperliquid will surpass Bitcoin within the year and that its market cap could rise from $25 billion to $100 billion. Other key points include Kraken raising $200 million at a reduced valuation of $13.3 billion, and the SEC clarifying that self-custodied DeFi frontends like MetaMask are not subject to broker-dealer rules, resolving a major regulatory uncertainty. The hosts also note the strong correlation between crypto and macro markets, with the S&P 500 posting one of its best 10-day rallies since 1950. They highlight MicroStrategy's continued Bitcoin acquisitions and the potential of real-world asset (RWA) tokenization as a key trend. The discussion concludes with skepticism towards many L2 projects, predicting a wave of protocols truly going to zero as capital concentrates in proven assets like Bitcoin and Hyperliquid.

a16z: The Next Frontier of AI, The Triple Flywheel of Robotics, Autonomous Science, and Brain-Computer Interfaces

a16z presents a comprehensive investment thesis for the next frontier of AI: Physical AI, centered on a synergistic flywheel of robotics, autonomous science, and novel human-computer interfaces (HCIs) like brain-computers. While the current AI paradigm scales on language and code, the most disruptive future capabilities will emerge from three adjacent fields leveraging five core technical primitives: 1) learned representations of physical dynamics (via models like VLA, WAM, and native embodied models), 2) embodied action architectures (e.g., dual-system designs, diffusion-based motion generation, and RL fine-tuning like RECAP), 3) simulation and synthetic data as scaling infrastructure, 4) expanded sensory channels (touch, neural signals, silent speech, olfaction), and 5) closed-loop agent systems for long-horizon tasks. These primitives converge to power three key domains: * **Robotics:** The literal embodiment of AI, requiring all primitives for real-world physical interaction and manipulation. * **Autonomous Science:** Self-driving labs that conduct hypothesis-experiment-analysis loops, generating structured, causally-grounded data to improve physical AI models. * **Novel HCIs:** Devices (AR glasses, EMG wearables, BCIs) that expand human-AI bandwidth and act as massive data-collection networks for real-world human experience. These domains form a mutually reinforcing flywheel: Robotics enable autonomous labs, which in turn generate valuable data for robotics and materials science. New interfaces provide rich human-physical interaction data to train better robots and scientists. Together, they represent a new scaling axis for AI, moving beyond the digital realm to interact with and learn from physical reality, promising significant emergent capabilities and value.

Conversation with Bitwise Advisor: From K-Shaped Economy to AI Taking Jobs, How Can Bitcoin Save the Younger Generation?

Jeff Park, a macro strategist and advisor at Bitwise, argues that the traditional financial system is broken, particularly for young generations. He describes a "K-shaped economy" where asset inflation enriches the wealthy while leaving others behind, with unaffordable housing as a key symptom. Park explains that real estate is often a depreciating asset due to maintenance costs and taxes, yet it remains unattainable for many young people due to distorted demand from global capital flows. He proposes Bitcoin as a superior store of value—scarce, portable, and free from maintenance costs or excessive taxation. By diverting capital away from real estate, Bitcoin could help lower housing prices and increase accessibility. Park also discusses the decline of traditional "smart investing" (e.g., value stocks) and the rise of "ideological investing" in non-correlated assets like crypto, luxury goods, and collectibles. On AI, Park warns it could trigger extreme social inequality by eliminating jobs while boosting corporate profits. He believes this will push younger generations toward Bitcoin, not only as a hedge but also as a symbol of decentralization and data sovereignty—offering an alternative to centralized AI systems that use personal data without fair compensation. He advises a diversified portfolio with Bitcoin as a core holding to hedge against currency devaluation and systemic risk.
