Runtime
ARC
Three names and one job each: a Blocklet describes an application, ARC runs it, AFS hands it the resources it needs.
ArcBlock's own software, running on ARC
ARC is the program that serves them: point it at a site or an app, and the same code runs it on your own machine or in the cloud. Five of them are below, including the page you are reading. Open any of them.
Running now
Each one was confirmed to be served by ARC, and opened in a real browser, on 2026-09-07. The list is kept by hand.
- ArcBlock new.arcblock.io The site you are reading. Articles, product pages, events, documentation and a glossary, all served by ARC.
- Aside www.aside.sh Save links, text, photos and files from the apps you already use, then find them again by tag or collection.
- arc arc.afsd.io ARC's own site: what it is, the one-line install, and the macOS desktop build.
- Chain Explorer explorer.arcblock.io ArcBlock runs two blockchains, main and beta. This is the reader for them: transactions, accounts, tokens and assets, as they were recorded.
- AUP Showcase showcase.afsd.io AUP is the Agentic UI Protocol. This is its gallery, running: interface pieces from forms to charts, with themes you can switch as you look.
What they run on
The links above are the part you check by opening. These two pages are the part you read: where ARC sits, and how the layers stack up.

ArcBlock Stack
Four layers, top to bottom: applications; components; compute, storage and blockchain together on one level; identity.
