You still don't get any meaningful security if old band members are
assumed to be untrusted and you don't use a public checkpointing mechanism.
Transfer of the title of being the real group must be a one-time only thing
for each version of the group, and must be impossible to backtrack from.

Hey, thanks again for the reply.
The only notable difference is that in my version you are checkpointing
the change in th blockchain.
You still have the very same form of signing, but you sign a slightly

Hey Natanael, Thanks for your response.
It's the chain of signatures always published in an accessible way so
that the original members can't doublespend and claim to be the task
group? Otherwise the blockchain approach is useful for you.

Now the original members b,c,d create an alternative history:
I assume that the original band has a majority of correct members.
Therefore at least two out of {b,c,d} are correct, and they will not create

Sorry, I should've read your formulation more carefully.
Don't worry about it :) We wrote lots of stuff since the first message,
it's hard to trace it back to the original message.
@Natanael: I think I understand now that our different opinions are due to
different concepts of adversarial

Hey,
Thank you for all the responses. I figured out that I left some important
details out, probably because I thought about it for a long time. I'm sorry
about that.
I will try to formulate it again:

Hi,
I am looking for some crypto primitive to solve a problem I have.
Assume that I meet a group of people. call it S. I get to talk to them a
bit, and
then they are gone.
This group of people walk together in the world. Sometimes they add a

Fascinating... If it helps, I know a couple of musos who are in that

they may have to say.

I guess, if it is really a band application as opposed to something more
abstract, it boils down to what you mean by
