ARC

OpenAI's Agents API turns the Codex loop into a hosted API: sessions, compaction, tools, sandboxes, plugins. That layer is real. It is still not a computer with identity, durable state, and an owner who can walk away with it. ARC attaches at the seam they already documented.

Making software no longer requires making a company first. When productive capacity is scattered across people and AI, collaboration, ownership, and value need a new organization.

Many companies are building compute for agents: sandboxes, VMs, even digital workers. They answer where untrusted code should run. What agents still lack is a machine that can last: identity, state, constrained authority, verifiable history, and the right to leave. We call that machine ARC.

AI 可以把需求變成軟體，但不會自動讓軟體、資料和身分屬於使用者。ARC 是 ArcBlock 為此建立的新架構。

Web Device is one of ARC's core capabilities: declare a .web/ folder anywhere in AFS, and the data and AUP under it get rendered server-side into a website, SEO checks, broken-link detection, and visitor analytics included for free. This piece covers how it differs from UI Device (/dev/ui/web), how to use it, and which situations call for which.

Blocklet 的執行時。它給開發者一個地方來執行以 Blocklet 描述的應用，連同那個 Blocklet 宣告自己需要的資源。

AFS（Agentic File System）把與任務有關的檔案、服務和正在進行的工作組織成可檢視的資源檢視。它不是把一整台機器或一堆 API 交給 agent，而是給任務一塊有名字、有邊界的工作範圍。

AUP（Agentic UI Protocol）先表達應用要呈現什麼、可以做什麼；runtime 再根據裝置能力呈現合適的部分。重點不是複刻同一張螢幕，而是讓同一項應用保留自己的內容和動作。

Blocklet 是 ARC 的可部署單元。它把應用宣告的內容、設定和執行需求放在一起，讓開發者面對的是一個清楚的應用單位，而不是散落在不同位置的部署線索。
