* [VC HTTP Authorization Conversation](https://lists.w3.org/Archives/Public/public-credentials/2021Jun/0009.html)Adrian Gropper June 2
The diversity of our community is a plus. To begin a conversation on VC access controls, I suggest this short intro to the differences between OAuth 2.0 and GNAP:
- [Hygiene for a computing pandemic: separation of VCs and ocaps/zcaps](https://lists.w3.org/Archives/Public/public-credentials/2020Dec/0028.html)
- You *could* implement zcap-ld on top of VCs…
- However, you're actually squishing together what should be a separation of concerns in a way that will become *unhygienic*. Like a lack of proper biological hygiene, the result is sickness in our computing systems.
- The observation of "these things seem so similar though!" is true, but you can already make that claim even if you're just looking at the linked data proofs layer. VCs and zcap-ld diverge from there for two very separate purposes: what is said, and what is done.

This week’s CCG teleconference had a great discussion about object capabilities
> Alan Karp: I've been doing capabilities since I reinvented them in 1996 and I want to make sure we get it right, because when newbies start to use them there are plenty of mistakes that can be made

> A capability or an OCAP is an unforgeable, transferable, permission to use the thing it designates ... it combines designation with authorization

> The 3Box Labs team recently published [a new standard for creating capability containers](https://github.com/ChainAgnostic/CAIPs/pull/74)for accessing decentralized data to the [Chain Agnostic Standards Alliance](https://github.com/ChainAgnostic/CASA). Capability containers are an approach for managing advanced data security and permissions, commonly referred to as “Object Capabilities” or “OCAPs.”

* [a few thoughts about zcaps](https://lists.w3.org/Archives/Public/public-credentials/2021Apr/0036.html)Nikos Fotiou
I was reading zcaps draft, as well as related work, mostly macaroons ([https://research.google/pubs/pub41892/](https://research.google/pubs/pub41892/).
Something that I found confusing about capability documents is that they do not make clear the actions they concern. For example from this[](https://w3c-ccg.github.io/zcap-ld/#example-1)[https://w3c-ccg.github.io/zcap-ld/#example-1](https://w3c-ccg.github.io/zcap-ld/#example-1)it is not clear that this is a capability for "driving a car".

After ruminating on ZCAPs, VCs, DIDs, and DID Documents over Easter dinner, it occurred to me that we're on the verge of creating a model for a "verifiable" economy...

I see all of this converging into a Capability Authorization-enabled Decentralized Object Model. “More news at 11…”
Updates on Kepler including implementing support for [CACAO-ZCAPs](https://github.com/spruceid/cacao-zcap), improved the `put` function to make it easier to store objects of different types, and added support for listing objects by prefix: [kepler-sdk#40](https://github.com/spruceid/kepler-sdk/pull/40)[kepler#115](https://github.com/spruceid/kepler/pull/115).

these are the types of use cases that we think can be created and enabled across the web as an open, interoperable standard. And some of it crosses into the work we're doing as[part of the Decentralized Identity Foundation](https://blog.fission.codes/fission-demo-day-may-2021/), too.
