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.

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 services already use credits to meter storage, compute, and API calls. As Agents begin to act across systems, the important work is not giving those units a fashionable name. It is making the rights, authority, and usage they represent possible to verify and reconcile.

支払いは AI Agent と Blockchain の最も目に見えやすい接点だ。しかし、より根本的な問いは、Agent は誰なのか、誰が認可したのか、何をできるのか、問題が起きたときにどう照合するのか、ということにある。

An agent cannot exist only as a platform account and an API key. DID can provide a portable, long-lived identity anchor, but authorization, runtime proof, revocation, and audit still have to do their own jobs.

AFS has a design principle we call Small World: every agent, every app, every process sees not the global world, but a small world projected specifically for it. Anything outside that world isn't "access denied". It simply doesn't exist. Here's where the idea comes from, why it's more than a security mechanism, and how to try it yourself.

Blocklet のランタイム。Blocklet として記述されたアプリケーションを、その Blocklet が必要と宣言したリソースとともに実行する場所を開発者に提供します。

DID はデジタル識別子です。保持者と検証者が、そのアイデンティティを誰が管理し、ある主張が誰に関わるかを確認するために使います。DID はウォレットではなく、アプリケーションのアカウント、サインイン方法、権限ルールを置き換えるものではありません。

verifiable credential は issuer が subject について出す署名付きの声明です。verifier に、source のない screenshot や伝聞の assertion より具体的に検査できるものを与えます。
