Emergency Reading: Threshold, Proxy Re-signature Cryptography with Privacy

No speaker, no investor pitch deck, no hand-holding, no fluff -- this Sunday we will be discussing Threshold, Proxy Signature Cryptography.

"A proxy signature scheme allows a designated
party to sign on behalf of the original signer. However, a dishonest
proxy signer can manage to sign arbitrary messages and
jeopardize the original signer’s benefit. Alternatively, a proxy
re-signature scheme allows the original signer to delegate his
signing right in a decentralized manner, to a delegatee and a
semi-trusted transformer. In order to protect the privacy of the
delegatee, a proxy re-signature scheme with privacy consideration
was recently introduced. "

That being said, the goal of this is to learn and help each other, so bring questions and don’t expect to know everything!
