Hi, I recently read the article Threshold Signatures, Multisignatures and
Blind
Signatures Based on the Gap-Diffie-Hellman-Group Signature Scheme, written

Hey. I want to thank everyone for the helpful answers. They were very
interesting to read.
From what I understand, the group I'm looking for is an elliptic cure with
a weil pairing. (Jonathan mentioned bilinear map, I assume that means the
same thing?)
The C code for the Pairing based cryptography
calculations.
The naive solution proposed in my first message will still outperform the
most efficient Bitcoin based solution. (Because it is O(log(n)) network
complexity).

Hey
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.
I think the naive solution I proposed in my first
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
different message (transfer of a colored coin, one Satoshi worth of
Bitcoin, to a new

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

I guess, if it is really a band application as opposed to something more
abstract, it boils down to what you mean by descendants. At least one
founding member left
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
person to
their group, and sometimes they remove one
at its core on a special form of
trusted entity called the supernode. In addition to its ability to manage
payments, the supernode should allow to securely exchange computation and
storage services for money.
