Explainer·Sep 16, 2026 Bookmarking is a runtime capability, not a site plugin Bookmarking and notes should not be rebuilt on every site. Arc ships them as a default-on runtime capability: hidden until you log in, easy to turn off, or bound to buttons the page already has.
Opinion·Sep 15, 2026 The CLARITY Act Is Dead. DAOs Died Long Ago. Is AI a New Hope? A blockchain builder reflects on the Senate vote, token governance, and whether AI agents can do any better.
Opinion·Sep 14, 2026 CLARITY Act or Not, Let’s Clarify ABT Clear law matters, but a product must also explain what its token does, who controls it, what rules apply, and how participants reconcile the record.
Opinion·Sep 14, 2026 On the Eve of the CLARITY Vote: A Blockchain Builder's Case for Clear Boundaries We need more than one crypto-friendly administration. We need legal boundaries that builders can follow across administrations.
Opinion·Sep 14, 2026 Accepting Payments Is Not Issuing a Stablecoin Issuing a stablecoin, accepting payment, and operating a digital service are different systems. Most applications need billing and credits, not a currency of their own.
News·Sep 13, 2026 What's next: ARC, one real application at a time 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.
Opinion·Sep 11, 2026 OpenAI's Agents API is a harness. ARC is a new kind of computer for agents 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.
News·Sep 9, 2026 ArcBlock’s new website is live. ARC takes the stage. ArcBlock’s new website runs on ARC, with all implementation code written by AI coding agents. Explore the new site and the technology behind it. The previous site remains available for about 30 days.
Explainer·Aug 27, 2026 A globe you can put on the page A rotating globe on a page is not decoration bolted under the text. It is a layout component: figure, scene, or backdrop. The homepage already uses it. This article puts several in the reading column.
Explainer·Aug 27, 2026 Light on the page, not a picture of trees Type on a white field is a document. Light moving over the type is a room. leaf-shadow is that overlay; gobo-loop is how you mint a new clip from a sentence.
Opinion·Aug 21, 2026 Equalized capability does not automatically concentrate When AI equalizes the ability to build, control does not automatically tighten. Many small units and home tools can coexist; super-individuals and giant canteens are not the default.
Opinion·Aug 21, 2026 If you still picture the old software and the old software company, you will misread this shift Many people still imagine software as slow, expensive craft, and software companies as hiring engines. Both have changed. Building it is no longer the main bottleneck.
Explainer·Aug 21, 2026 AI can draft the homepage five ways. You pick on the real page. A Web Device page can keep several finished renders on one URL. An agent drafts the set; a person picks on the real page; visitors only enter an A/B split if you open it.
Product·Aug 20, 2026 Where your AI spend goes: an introduction to Agent Observability Every model call an agent makes is written to a ledger. This is where those ledgers live, which of the three pages answers which question, whose data you are allowed to see, and the two boundaries you have to know before you read a number off any of them.
Opinion·Aug 18, 2026 After Software: Collaboration, Production, and How Value Gets Shared 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.
Engineering·Aug 18, 2026 Unattended (Autopilot) Loop Engineering: We Open-Sourced New Agent Skills That Free Your Hands The last pair of skills got us out of two-terminal paste. These four take you off duty. People spend more time on decisions, taste, and responsibility. Agents do the busywork. issue-review, issue-sweep, pr-review, and pr-sweep are open source.
News·Aug 14, 2026 ARC Now Supports the MCP 2026-07-28 Specification 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.
Explainer·Aug 14, 2026 Storytelling with Immersive Gallery Pair a cover still with a short loop in the same folder-backed gallery so stage and story plates can paint fast, then breathe. One small way Web Device treats writing as something that can be performed.
Explainer·Aug 14, 2026 Slides that read like an article A Markdown deck can be published as an article of its own: a player on top, and below it every slide becomes a card with its narration beside it. No separate slide tool, no embedded frames. This article is itself the demo.
Engineering·Aug 13, 2026 We Open-Sourced a Skill So Code Agents Don't Eat Your Drive with Worktrees We open-sourced another agentloop skill: git-hygiene. More parallel agents means more local branches and worktrees; a 1TB drive fills faster than you'd guess. The skill proves a delete is safe before it runs it.
Explainer·Aug 11, 2026 One Folder of Photos, Several Ways to Look Folder-backed media gallery keeps a set of images next to the article and lets you choose grid, mosaic, stage, story, and more—without a second asset system.
Opinion·Aug 10, 2026 The Infrastructure Came First. The Residents Are Arriving. 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.
Opinion·Aug 10, 2026 Builders Change. Your Property Stays. 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.
Engineering·Aug 10, 2026 What `arc skill` Is Today (and What It Is Not) arc skill ships a small catalog of built-in how-to booklets and can drop them into your agent skill folders. That is useful—and incomplete next to gh skill or AFS’s own .skills trees. Here is the plain map, a short how-to, and the open design gap.
Opinion·Aug 9, 2026 Agents don't need a better sandbox. They need a computer of their own. 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.
Explainer·Aug 9, 2026 Review Mode on Web Device: What You See Is What You Review Open the page readers actually see, mark what is wrong, and leave an executable note next to the content. That is still Web Device in-page review. The overlay is quieter now: a glass island, a composer on the target, optional pointing and freeze.
Explainer·Aug 9, 2026 When a writing agent should leave the page without a figure Writing agents on this site plan figures at outline time, then run kind-specific skills. Zero figures is valid. When a figure earns its place, the pipeline leaves a structured source, a rendition, and a text fallback.
Opinion·Aug 8, 2026 Don't Take Your Project to an Agent Factory. Invite Agents Into Your Own Realm. The important question is not whether an AI model runs locally. It is whether a project remains a place where its people can see, govern, and recover its context, authority, evidence, and change.
Opinion·Aug 7, 2026 CLARITY Is Not About "Legalizing Tokens"—Here's Why the Industry Still Needs It CLARITY is not a pass for anything labeled a token. It is an attempt to distinguish a real right, a resource claim, and market activity from a label. The bill is still pending, and that distinction still has to prove itself.
Explainer·Aug 7, 2026 Create Slide Decks That Live Inside Articles and Docs Markdown Slides lets one Markdown record become an interactive deck inside an article or document while keeping the complete page readable.
Opinion·Aug 7, 2026 A Useful Token Must First Stand for Something of Real Value 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.
Opinion·Aug 3, 2026 Context Is Not Cognition The AFS paper asks how context can become a systems problem worth engineering. It does not claim that cognition has been solved.
Opinion·Aug 3, 2026 AFS Is Not Git, and It Does Not Put Meaning in a Tree A file path can place an operation in a declared resource view. It is neither a semantic relationship nor a way to reduce AFS to Git.
Engineering·Aug 3, 2026 The Web Content System on ARC: Not Understanding Your Content Is What Makes It Simple WordPress and Astro both ask a site to declare its content model. That is not a flaw; it is a different trade-off. ARC's Web Device tries to make common web work a runtime, while leaving the meanings of products, terms, and events to object data and application components. This is about where that boundary belongs, and what still has to be supplied to make it hold.
Opinion·Aug 3, 2026 Context Is More Than Inventory A paper about context ultimately faces relevance, change, and governance, not capacity alone.
Opinion·Aug 3, 2026 When Multiple Agents Write, Start by Separating Their Worlds The hard part of multi-agent work is not putting every agent in one directory. It is making clear what each one may write, what happened, and who reconciles the result.
Opinion·Aug 2, 2026 AI Agents Need More Than a Wallet Payment is the most visible connection between AI Agents and blockchains, but the more fundamental questions are: who is the Agent, who authorized it, what can it do, and how do we reconcile what happened when something goes wrong?
