So sad. I was just there two weeks ago. The view was spectacular.

The past few days, I’ve felt a bit like a leaf in a tornado as I’ve been making my way from one place to another during our Band of Brothers: Legacy event in Gettysburg. During the few opportunities that I’ve had to look at my phone, I’ve been seeing images like these of the aftermath of the fire at The Eagle’s Nest. Once I get home and get settled, I may sit down and organize a few thoughts, because I certainly have a few.

An in-depth engineering blog explaining how we built our Blockchain Explorer entirely on ARC (Agentic Realm Computer). From blockchain data and AFS to AFS-UI and the underlying architecture, we walk through how the pieces fit together to power a real-world application. Not just a demo or a concept — a working application built on our next-generation agentic computing platform. arcblock.io/en/articles/chai…

We will move everything to ARC(Agentic Realm Computer) and sunset Blocklet Server 1.x services by the end of 2026. arcblock.io/en/articles/bloc…

We've decided to sunset Arc on December 22, 2026. That's not an easy sentence to write. We spent years building Arc and celebrating each and every release along the way: we have so much pride and love for what we made alongside the Arc community. Our priority is to deliver best-in-class security for our members. Keeping a browser secure takes constant, dedicated work that is only increasing in the age of AI. Dia was built from the ground up to meet today’s security standards, so that's where our engineering and security teams will focus moving forward. We've worked to make switching to @diabrowser as easy as possible for Arc members. Here's how: · Your passwords, bookmarks, extensions and history come over to Dia seamlessly. · Spaces, Folders, and Tab Groups are in Dia and import over with your data intact. · Dia now surpasses Arc benchmarks in stability, speed, and security. · The browser features you use in Arc are free in Dia, and the AI is optional. Thank you for using Arc, for pushing us to make it better, and for building alongside us. The team that made Arc is the same team behind Dia, and some of our most ambitious work is just ahead. We'd love for you to be there with us when it lands.

Next week, we’ll be attending Cloudflare Connect in San Francisco! Ahead of the event, we’ve put together a quick explainer showing how ARC (Agentic Realm Computer) integrates Cloudflare’s infrastructure and services in our production environment. It’s a practical look at how we’re combining Cloudflare’s capabilities with our agentic architecture to build and operate real-world applications. arcblock.io/en/articles/arc-…

Security Advisory: Blocklet Server 🔐 We’ve recently detected attacks targeting vulnerabilities in older versions of Blocklet Server, including evidence of exploitation. Our team has investigated the incidents and released security fixes. So far, our investigation has found no evidence of data loss or financial impact. If you’re self-hosting Blocklet Server, please take action: Update to the latest version immediately. Rotate your admin secret key (SK). Audit your deployment for suspicious activity or unauthorized access. We’re continuing to monitor the situation and will share further updates as appropriate. Security and transparency have always been fundamental to ArcBlock, and that commitment continues as we move toward ARC. Thank you for helping keep the ecosystem secure.
