The Best Personal Agent May Be the One That Does Less
Trying Instinct made me rethink personal AI: keep my authority, protect my attention, and quietly look after the things I would otherwise forget.

Why We Built Aside
We watched great tools change hands or disappear. That is why ArcBlock built Aside: an ARC-powered iPhone app that sends every Share back to a place you own.
DiscussKit, Rebuilt on ARC
DiscussKit has been rebuilt on ARC, and ArcBlock Community has completed its move. This is a new division of responsibility across discussions, identity and user-owned data.

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.
Agents Need an Identity. DID May Be the Best Place to Start
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.
The Market Sees a Downturn. Builders See the Beginning of a New Era.
Why we are doubling down on blockchain, Passkey-native wallets, and decentralized applications with AI and multi-agent engineering at a moment when Binance's October incidents, midterm election shocks, talent drain to AI, and AI-armed attackers have plunged crypto into panic.

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.
Web Device: Declare a Website, Then Pick the Right Path
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.
Small World: Every Agent Lives in Its Own Projection
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.

Why Aside Is Built for Working with Agents
Aside was designed around both the human experience and agent access. AFS lets both work with the same library, while structured interactions give people a way to make decisions and keep the work moving.
A Security Hardening Release for Blocklet Server
A security review of Blocklet Server found issues in authorization, logging and input validation. All releases up to 1.17.12 are affected; the fixes ship in 1.17.13-beta-20261019-082907-fe71de61 and later. Hosted apps are already patched. Self-hosted servers should move to the beta channel and restart.
Apps Are Infinite. Human Context Is Finite.
AI makes applications easier to generate. The harder architectural question is whether our identity, memories and judgment can survive replacing them.
