1213The Urbit address space is now live on the Ethereum blockchain. We’re calling the PKI ‘Azimuth’ and you can find it at [`0x223c067f8cf28ae173ee5cafea60ca44c335fecb`](https://etherscan.io/address/0x223c067f8cf28ae173ee5cafea60ca44c335fecb) or [`azimuth.eth`](https://etherscan.io/address/azimuth.eth). Owners of Azimuth ‘points’ (galaxies, stars or planets) can use [Bridge](https://github.com/urbit/bridge/releases) to manage them and view their balance now.

1515Sometime in the next few days, owners of Azimuth points will be able to boot Arvo, the Urbit OS, from their Azimuth point and request access to one of our 'cities': private communities for chat and discussion. These new cities use Landscape, a brand new UI for using Urbit in the browser.

1717This means you can boot a deterministic OS from an identity you own, join a totally independent, decentralized and self-governing network and run a clean, simple UI. Pretty exciting. Is it ready for ordinary users? Definitely not.

6159So, how do you get an Azimuth point? We've left that question unanswered intentionally. Azimuth points are meant to be like digital land, not currency. They should change hands slowly. In order to get an Azimuth point, you'll need to find someone who already has one and is willing to part with it.

7269There's plenty of work to do, though. Should you be building on top of Arvo? Probably not yet. The kernel and kernel modules are really where the work still lies. We build things on top of Arvo, and in doing so it's pretty clear that the system can be better. Clay (the filesystem) and Gall (the application model) are due for a rewrite. A complete rewrite of the web server, Eyre is almost finished.
