搭上 DePin 赛道增长快车,代币价格较年初翻倍的 Livepeer 又有了新动作 —— 推出 AI 子网


编译:Alex Liu,Foresight News


Livepeer 于 2017 年推出,是第一个完全去中心化的直播视频流媒体网络协议。该平台旨在提供一种基于区块链、经济高效的解决方案替代传统集中式广播。它通过让制作人在平台上提交作品,然后负责重新格式化和分发内容给用户和流媒体平台,旨在改革快速增长的直播视频流媒体和广播行业,引入去中心化生态系统。


简单点讲,通过 DePin 设施,使用 Livepeer 只需要花费传统解决方案很小一部分的成本,就能够用去中心化的方式将视频内容无缝集成到应用中。


DePin 赛道在今年初热度猛增,LPT 也搭上了增长的快车,代币价格相较年初翻倍。小编作为一年前 10 块买入 9.8 全部卖出的韭菜,决定痛定思痛,仔细研究 Livepeer 的新动作 —— 推出 AI 子网。


创新求变, Livepeer 推出 AI 子网


在生成式 AI 时代,视频创作迎来了新的变革。


自从 Open AI 的 Sora 演示展示了通过输入文本提示即可创建视频的可能性以来,生成视频领域迅速发展。开源 AI 视频模型 Stable Diffusion 在短短两个月内用户量突破了 1000 万。然而,生成 AI 视频工具的前景面临严峻挑战。价值 490 亿美元的 GPU 市场由少数全球互联网垄断企业,如 NVIDIA、Microsoft Azure 和 Amazon Web Services(AWS)控制,导致价格上涨,并造成全球 AI 计算瓶颈。


因此,Livepeer 推出了 Livepeer AI 子网:首个具有 AI 计算能力的去中心化视频处理网络。Livepeer AI 子网通过利用 Livepeer 的数千个 GPU 开放网络,提供低成本、高性能的处理服务,解决集中式 AI 计算的结构性问题。基于 Livepeer 的去中心化视频处理网络架构,子网提供全球可访问的、经济实惠的开放视频基础设施,并通过区块链代币经济激励无限扩展。


Livepeer AI 子网具体是什么?


AI 子网是 Livepeer 视频基础设施网络的分支,提供安全开发和测试新去中心化 AI 媒体处理市场和工具的沙盒环境。在 Livepeer 网络将继续专注于视频转码和计算的同时, Livepeer AI 子网将满足日益增长的 AI 计算需求,处理诸如升级、字幕生成和识别等任务,并支持开发者运行特定视频和媒体任务的模型。


该子网允许视频开发者在其应用中添加一系列生成式 AI 功能,如文本到图像、图像到图像和图像到视频转换。

建立 Livepeer AI 子网的原因


AI 视频工具降低了创作门槛,任何人只需通过几个文字命令即可创建原本需要场地、专业团队和数小时编辑的画面。随着这些工具的普及,全球集中式 AI 计算瓶颈将进一步加剧。此外,去中心化 AI 基础设施还能解决高度集中的服务器网络固有的单点故障风险以及 AI 生成内容引发的信任和真实性危机。


Livepeer AI 子网通过提供全球可访问的超低成本基础设施、开放和无许可的 AI 媒体市场以及内容验证和真实性解决方案,为创建可持续和盈利的开放 AI 视频基础设施提供了选择。


Livepeer AI 子网的工作原理


Livepeer 采用去中心化的按任务付费模式,允许开发者按需提交和支付任务费用,而无需预订昂贵的计算容量。开发者可以根据所需性能和网络供应情况自行设置愿意支付的价格。


Livepeer AI 网络架构的两个关键组件是:


  1. AI 协调节点:这些节点执行 AI 任务,保持 AI 模型在其 GPU 上「预热」以便即时处理,并能动态加载模型,优化响应时间和资源利用。
  2. AI 网关节点:这些节点管理任务流,依据能力和当前负载将任务分配给合适的协调节点,确保高效的任务分配和系统可扩展性。


该图说明了 Livepeer 如何根据效率将任务分配给分布式 GPU 网络,而不是通过集中式服务器引导 AI 处理请求。


无限可扩展性


Livepeer AI 网络基础设施设计为可无限扩展,允许根据需求轻松集成额外的协调和网关节点。通过专用的 AI-runner Docker 镜像执行 AI 模型,简化部署并增强新管道的可扩展性。未来的开发将进一步提升性能并扩展容器的能力,以支持越来越复杂的 AI 模型和自定义用户定义的管道。


在 AI 子网上处理任务的技术工作流。网关节点将任务传递给协调器,协调器可能运行相同或不同管道的多个 AI-Runner Docker 容器。这些管道可能已经拥有所请求的模型,或可以根据需要动态加载它们。


参与 Livepeer AI 子网


硬件提供者:通过贡献 GPU 赚取费用


现有的 Livepeer 协调员可以设置并运行 AI 协调节点,执行文本到图像、图像到图像和图像到视频的推断任务,增加其现有转码收入。


开发者:将模型引入网络作为 AI-Worker


开发者可以定义和部署自定义管道和工作流程,以确保其应用处于 AI 和视频技术的前沿。开发者还可以设置 AI 网关节点,测试和完善其应用,访问 AI 任务的 API。


Livepeer AI 子网的推出标志着该项目的重要里程碑,也是 Livepeer 提供全球开放视频基础设施使命的下一步。随着生成式 AI 将在未来几年大幅增加视频内容的创作量,Livepeer 网络旨在确保其具备支持这一增长浪潮的能力。

The Full Story of How Crypto Unicorn Blockstream Is Mired in Serious Fraud Allegations

This article details serious allegations of fraud against Bitcoin infrastructure company Blockstream, founded by Bitcoin pioneer Adam Back. In June 2024, investigative account NatInfoSec published a report accusing Blockstream's mining note (BMN) program of potentially operating a multi-billion dollar scheme with Ponzi-like characteristics. The core allegations focus on Blockstream Mining Notes (BMNs), which offer investors fixed annual yields up to approximately 20% from Bitcoin mining. NatInfoSec's investigation raises several key issues: 1. **Suspicious Hashrate & Payout Capacity**: The analysis suggests Blockstream would need 20-45 EH/s of mining power to cover its BMN obligations, but its public dashboard shows only around 15 EH/s. Furthermore, no verifiable public evidence (e.g., grid connection records, import data) was found to support the massive mining operation required. 2. **Questionable Payout Source**: The BMN contract allows Blockstream to use Bitcoin from *any source* (Substitute Performance BTC) to fulfill investor payouts, raising concerns that payouts may not come from actual mining revenue. 3. **High-Risk, Fixed Returns**: Offering ~20% fixed yields in the volatile, cyclical Bitcoin mining industry is viewed as highly unusual and requires clear explanation. 4. **Undisclosed Criminal Record of Key Figure**: Christopher William Cook, a key figure in Blockstream's mining operations and CEO of spin-off Exacore, was found to have a federal felony conviction for mail fraud in 2008, a fact not disclosed in BMN offering documents. His background was also allegedly embellished. 5. **Potential Contagion to BSTR SPAC**: Questions were raised about whether these liabilities and Cook's record should have been disclosed in the SEC filings for Bitcoin Standard Treasury Company (BSTR), a separate Adam Back-associated firm planning a SPAC merger. The crypto community is divided. BitMEX Research validated Cook's criminal record and expressed concern over the high yields but found other evidence lacking or misleading, noting the legal separation between BMN, Blockstream, and BSTR. Blockstream defenders, like Samson Mow, argue the mining is real. Critics, however, emphasize the lack of independent, verifiable proof of the mining operation's scale and the true source of investor payouts. The article concludes that BMN remains shrouded in key unanswered questions regarding its actual size, the verifiability of its underlying mining assets and payouts, the source of its high yields, and the full role and disclosure concerning Chris Cook. Blockstream had not issued a comprehensive response at the time of writing.

The Full Story Behind Encryption Unicorn Blockstream's Deep Entanglement in Serious Fraud Allegations

This article details allegations of serious fraud surrounding the crypto company Blockstream, founded by Bitcoin pioneer Adam Back. Investigation account NatInfoSec accuses Blockstream of raising billions through its Blockstream Mining Note (BMN) products, which offer high fixed yields of up to 20% from purported mining revenue. The core allegations are: 1) Blockstream's public mining hash rate (15 EH/s) appears insufficient to cover the massive payout obligations from sold BMN notes, raising questions about the true source of investor payouts. 2) Key executive Christopher William Cook, central to the mining operations, has a prior federal conviction for mail fraud, a fact not disclosed to investors. Cook's background and lavish lifestyle are highlighted as red flags. 3) The structure allows payouts from any source of BTC, not necessarily mining revenue, which critics argue gives it Ponzi-like characteristics. The controversy also touches on Bitcoin Standard Treasury Company (BSTR), a related entity planning a SPAC上市. Critics question whether BMN's liabilities and Cook's record should be disclosed in BSTR's filings. BitMEX Research offered a tempered analysis, confirming Cook's criminal record is likely true and the high yields concerning, but found other claims like insufficient抵押证据 less substantiated. Community debate centers on the need for verifiable proof of Blockstream's mining output and revenue. The article concludes that while fraud is not proven, BMN presents significant, unresolved questions regarding its actual scale, the source of its high fixed returns, the verifiability of its mining operations and payouts, and the full disclosure of associated risks and personnel backgrounds. Blockstream has not yet issued a formal response.
