ARC

The new site is live. Here is how we plan to bring ARC into the community, data spaces and everyday applications, with migrations, new products and builders taking part along the way.

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.

ARC already spoke MCP. This upgrade aligns that surface with MCP 2026-07-28: stateless streamable HTTP and standard OAuth discovery so third-party agents can reach Blocklets without a special bridge.

Not a pivot from blockchain to AI. The harder claim is simpler: roads and utilities can be built early, but a digital city only comes alive when residents who can work around the clock walk in.

Most people will not manage API keys. They will hire agents. The real question is not which model is smarter, but whose ground the worker stands on when the job is done.

ARC's mobile application surface. It gives supported ARC Blocklet experiences a coherent, app-like way to be used on a phone.

The command line for ARC — declare, build, deploy and inspect a site or a Blocklet from a terminal.

AFS (Agentic File System) turns the files, services, and active work relevant to a task into an inspectable resource view. Instead of handing an agent an undifferentiated machine or a pile of APIs, it gives the task a world with names and boundaries.

A useful system can distinguish the person, service, or agent taking an action; the party it represents; and the permission for that action. Treating all three as one shared secret makes a later decision harder to explain.

ARC is the runtime for Blocklets. It gives a developer a place to run an application described as a Blocklet, instead of making the runtime, the application, and its resource connections one unexplained deployment.

AUP (Agentic UI Protocol) lets an application express what is shown and what actions are available. A runtime then renders the parts that fit its device capabilities, instead of treating one screen's pixels as the application itself.

A Blocklet is ARC's deployable unit. It keeps an application's declared content, configuration, and runtime needs together, so the unit being run is easier to understand and manage.

An application whose important state does not sit only in one operator's database. What counts as decentralized varies a lot between projects, so the useful question is which part is checkable by someone outside.
