This work is continuing at Agoric https://agoric.com/.

It was also the inspiration for the Cosmos IBC protocol. https://github.com/cosmos/ics/blob/master/ibc/2_IBC_ARCHITEC...

So much good material in the capability security community, always way ahead of its time. It's heartening to see that at least some of it is trickling into standard industry practice.

Come on. If you have the 6gram "crypto" on the page, please don't have an expired certificate. I just stop reading at that point.

These ideas originated in the 1970s with the GNOSIS/KeyKOS[0][1] operating system. I wrote an informal summary here: https://github.com/void4/notes/issues/41

So they are old, but there's a wave of new projects using them again.

This is awesome, thanks!

Also, fwiw, the post didn't have the (2000) tag when I encountered the expired cert. Crypto isn't my strong suit, so my BS filter uses heuristic shortcuts. These shortcuts are often wrong.

this stuff is pretty old, and not sure how maintained anything there still is.

These old EROS/E sites are archived now, but others have pointed out that these folks are still hard at work at https://agoric.com

yes, I just meant that complaining about expired certificates probably didn't make sense given that context.
