<cel> hi, oed
<oed> sup
<oed> anything to do here today?
<cel> looks like not, unless you want to talk about things, other
contributors are unable to make this call
<cel> hi Johannes
Our Robot Overlords are scribing.
<cel> Usually Juan has been running this call, but unable to make
it today.
Charles E. Lehner: Did:pkh is a DID method where the DID subject
is a public key hash, basically.
Charles E. Lehner: Johannes: what is the motivation?
Charles E. Lehner: A main motivation is for blockchain account
addresses [scribe assist by Charles E. Lehner]
Charles E. Lehner:
https://w3c-ccg.github.io/security-vocab/#blockchainAccountId
<cel> ... specifically, we see this in the CCG's security
vocabulary blockchainAccountId property
Charles E. Lehner: Johannes: how do we link blockchain account
addresses with DIDs and VCs?
Charles E. Lehner: Yes, with did:pkh the blockchain account
address is in the DID [scribe assist by Charles E. Lehner]
Charles E. Lehner: Johannes: right. what is the use case? say i
have a blockchain account address, how would i use did:pkh?
Charles E. Lehner: With did:pkh currently, you can convert a
blockchainAccountId value to a did:pkh DID [scribe assist by
Charles E. Lehner]
<cel> ... then you can issue VCs, generate VPs, sign other
things, using the public key that hashes to that blockchain
account id
Charles E. Lehner: Johannes: ok
Charles E. Lehner: Johannes: so i could share VPs, and they would
be linked to my blockchain account address, just like on-chain
assets, so like the on-chain assets would be linked to the VCs?
Charles E. Lehner: What do you mean by on-chain assets? [scribe

Charles E. Lehner: Johannes: one of the things you could do is
say Johannes owns this NFT, so it would be linked...
Charles E. Lehner: I think it's a little different because we
don't have an idea of transferability... [scribe assist by

<cel> ... relevant:

by Joe Andrieu on NFTs vs VCs
<cel> ... so if the issuer is a did:pkh, it stays that issuer,
and if the subject is a did:pkh it stays that subject
<cel> ... do you think this is a limitation/problem, or it's
useful as is?
Charles E. Lehner: Johannes: Useful as is
<cel> ... Is this call weekly?
Charles E. Lehner: Yes, we'll try to send more agenda emails
[scribe assist by Charles E. Lehner]
<cel> ... Thanks for coming
Charles E. Lehner: Johannes: thanks
