So glad to hear them credit the original paper that Zcash brilliantly iterated on & actually made efficient: [ST99] Auditable, Anonymous Electronic Cash; by Sander, Tomas and Ta-Shma, Amnon; CRYPTO' 99
Some deep historical lore on how Zcash, in a sense, predates Bitcoin:
Paper's abstract below 👇👇
14 years later, Sander & Ta-Shma use ZKPs for anonymous payments 🤯 17 years later, @zcash launches! If only Satoshi read [ST99]... Well, we'd still be here because [GGPR13] was not out yet ()
Lots of interesting things in [ST99] if you look closely. First, Merkle forests (less succinctly known as Merkle mountain rages)👇
Second, nullifiers as serial numbers that are one-way hashed with some randomness.
Surprisingly, I think I just found an error with their "invalidation of funds" protocol (which is a bad idea anyway)
