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.
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.
THE COMPUTER BEHIND THE EXPERIENCE
Meet ARC. Make it yours.
The website you’re reading runs on ARC. Its pages, content, and interactions are brought together as a Blocklet. The same runtime supports very different experiences.
A SPACE FOR YOUR DATA

Formerly DID Space, ArcSpace is a data space for you and your applications, associated with your digital identity. Create a personal space, or connect an application with the access it needs.
