Brevis 发布 Pico Prism,在消费级硬件上实现了以太坊实时证明

深潮Published on 2025-10-15Last updated on 2025-10-16

Pico Prism(zkVM)在 RTX 5090 GPU 上性能效率提升 3.4 倍。

领先的零知识证明基础设施供应商 Brevis 于10月15日宣布,其 Pico Prism 已在消费级硬件上实现当前以太坊主网区块(45M Gas 上限)99.6% 的实时证明覆盖(12 秒以内)和 96.8% 的 10 秒以内覆盖率。

该突破表明,使用可获取的 RTX 5090 GPU 就能实现实时证明,无需昂贵的数据中心设备,使该技术在更广泛的部署中具备经济可行性,同时支持以太坊的去中心化目标。

性能表现超越了以往的解决方案

在与之前基准测试相同的 36M Gas 限制上测试时,Pico Prism 在各项指标上均大幅领先:

  • <10 秒覆盖率:98.9% 对比 40.9%(提高 141%)

  • 硬件成本:128K 美元对比 256K 美元(降幅 50%)

  • 平均证明时间:6.04 秒对比 10.3 秒(快 71%)

  • GPU 需求:64 RTX 5090 对比 160 RTX 4090 (降低 60%)

  • 性能效率(速度与成本综合):提升 3.4 倍

针对 以太坊 45M Gas Limit,Pico Prism 达成:

  • 99.6% 覆盖率(12 秒以内)

  • 96.8% 覆盖率(10 秒以内)

  • 平均证明时间 6.9 秒

Brevis 联合创始人兼 CEO Michael 表示:“数据本身说明一切。我们构建了能够处理当下以太坊区块生产量的基础设施,使用的都是面向广大用户的消费级硬件。这一性能表现完美契合以太坊去中心化目标。”

技术创新:分布式架构

Pico Prism 的出色表现源于从单机证明到分布式多 GPU 集群的完整架构重构。系统利用 Pico 模块化设计,将计算密集型任务分配给 GPU 并行处理,同时 CPU 负责设置任务。通过高度并行化流水线实现集群中 GPU 的最大利用率,多机扩展几乎线性加速,从而在 RTX 5090 消费级硬件上实现优异的硬件效率,相比需要昂贵或专用数据中心设备的方案更具优势。

推进以太坊扩容愿景

传统以太坊交易需要全球超过 80 万验证人独立重新计算,Pico Prism 通过加密证明实现验证规模化——由单一 prover 生成数学证明,其余验证者在毫秒级完成验证。

2025 年 7 月,以太坊基金会在路线图中提出实时证明目标:99% 覆盖率、10 秒内完成、硬件低于 10 万美元、功耗低于 10kW。Pico Prism 在消费硬件上的成就是向该目标迈出的重要一步,128K 美元的硬件成本虽略高于 10 万美元,但广泛可得的消费级 GPU 大幅提升了可及性。

可复现基准测试

Brevis 在 8 台服务器(每台配 8 块 RTX 5090 GPU,总计 64 块 GPU)上对 Pico Prism 进行了基准测试,并与之前的最先进方案进行了对比,所有测试均可复现,欢迎各方验证实验结果。Brevis 致力于推动开放、可复现的基准测试,以支持以太坊的透明度和技术卓越性。

面向生产的基础设施

Pico Prism 是 Brevis Pico zkVM 架构的分布式、多 GPU 演进版。Brevis 通过 ZK Data Coprocessor 技术已在生产环境中验证了零知识基础设施,目前为 PancakeSwap、Usual、Frax、Linea 和 MetaMask 等主要 DeFi 协议提供可验证计算支持。未来几个月,Pico Prism 计划在不到 16 块 RTX 5090 GPU 上实现 99% 实时证明,进一步接近以太坊基金会的目标。

关于 Brevis

Brevis 是高效、可验证的链下计算引擎,为现有智能合约区块链提供无限计算能力。通过零知识证明,Brevis 将数据密集型、高成本计算从链上卸载到低成本链下引擎,使 Web3 应用在保持 L1 安全信任前提下无缝扩展。

Upbit is Anxious: A Hasty Counterattack Aimed at Regaining Stablecoin Market Share

Title: Upbit's Rushed Counterattack to Reclaim Stablecoin Market Share Facing a dramatic shift in South Korea's stablecoin market, leading exchange Upbit launched a promotional campaign from July 26 to August 9, waiving the 0.05% trading fee for stablecoins paired with the Korean Won (KRW) and rapidly listing new stablecoins like RLUSD and USDG. This move is a direct response to its plummeting market share in this sector. Historically a duopoly with Bithumb, the market has been reshaped since October 2025 when Coinone permanently removed fees for USDC trading. By June 2026, Coinone led with 34.8% of stablecoin volume, followed by Bithumb (31.1%) and Upbit (30.1%). This contrasts sharply with the overall crypto market, where Upbit commands 60%. The data shows stablecoin demand is highly sensitive to fees, as users primarily buy them to transfer capital overseas for derivatives trading or forex arbitrage. South Korean exchanges have seen a net outflow of stablecoins for 18 consecutive months, totaling approximately 14.9 trillion KRW, underscoring their role as a cross-border capital conduit. Upbit's limited-time promotion initially boosted its daily stablecoin volume by 162%, but the surge was almost entirely in USDT (98.1% of volume). The newly listed stablecoins saw negligible, fleeting interest. Furthermore, the promotional effect quickly waned in the second week, with volume dropping 33% on weekdays. A concurrent weakening of the KRW also contributed to the trading spike, independent of the fee waiver. The analysis suggests that once the promotion ends, Upbit is unlikely to retain its temporary gains unless it matches Coinone's permanent zero-fee policy, forcing a choice between market share and fee revenue. Upbit's strategic push may be less about immediate profit and more about preparing for future regulatory shifts. With South Korea's *Digital Asset Basic Act* on the horizon, which will regulate KRW-backed stablecoins, and following Dunamu's (Upbit's parent) integration into Naver Financial to build a payment ecosystem, securing a dominant position in the dollar stablecoin distribution channel holds long-term strategic value. However, potential regulatory conflicts could prevent Upbit from listing a future Naver-issued KRW stablecoin, making the current fight for dollar stablecoin flow even more critical.

Michael Saylor Compares Bitcoin and Gold!

Michael Saylor, founder of MicroStrategy, argues that Bitcoin fundamentally changes how wealth is stored and transferred by transforming digital scarcity into economic value. He describes Bitcoin as the first digital monetary network, combining computers, digital networks, and cryptography. It digitizes monetary assets, allowing their supply to be controlled by public protocols rather than institutions, thus converting economic value into information transmissible over global networks. Comparing Bitcoin to gold, Saylor states that while increasing Bitcoin's supply is harder, its integration with software and transfer is easier. He highlights Bitcoin's proof-of-work mechanism, which ties it to the physical world by consuming real energy to secure the ledger, making past transactions immutable. This creates a shared security system involving miners, energy companies, and investors. Saylor suggests "digital monetary energy" is a more accurate term than "digital gold." He emphasizes that the Bitcoin network is an adaptive ecosystem of miners, nodes, developers, and users. Its core design is intentionally simple, focused on maintaining a secure ledger for scarce digital assets, with complex functionalities built in higher-layer applications. This architecture allows Bitcoin to serve as a foundation for transmitting value and fostering innovation in payments and financial services. Saylor notes Bitcoin's deeper impact lies in creating digital sovereignty, where private keys give individuals permissionless control over their economic power, with ownership verified mathematically, not by institutions. He concludes that while gold's physical scarcity makes it money, Bitcoin's digital scarcity does the same, characterizing Bitcoin as the monetary energy of the digital age.
