The power of DBCs on Safe Network

[Nigel]

Looks like ring signatures amongst elders may get some testing soon… I wonder if all these different implementations (blind sigs also in the works) are being tested against each other to test for the best balance between speed, privacy/fungibility or if the point is that any signing that Elders do is so which Elder signed what is unlinkable.
Seems like a nice way to protect Elders while also ensuring that Elders can’t link what they are signing.

Don’t know much about the benefits of ring signatures besides what’s in the name.

Ring Signatures

Ring Signatures, as used in Monero and other cryptocurrencies, are a method to obscure the transaction history by hiding in a group.

In a ring signature, Alice signs a transaction using (1) Alice’s private key, (2) Alice’s public key, and (3) other people’s public keys. Anyone can verify Alice’s signature using the set of public keys, but they’re (usually) unable to determine who the true signer was because there are multiple equivalent public keys.

As such, ring signatures are a form of automatic mixing. Links still exist, but there are so many of them, that it may be too difficult to analyze. In Monero at present, there are 11 possible signers: the real one plus 10 others. So this is like hiding in a crowd of 11 people… better than standing alone, but not super comforting if a bloodhound is sniffing around.

Would share the link but from my understanding the author likes to keep a low profile, privacy respected.
