janusz(@januszg_):some new research for shielded csv from @gusgutoski applying ideas from zcash tachyon to improve scalability some background: a bottleneck with zerocash-based transaction protocols is the need for nullifiers - unlinkable revocation tokens used to detect double-spending. shielded csv is no different all nullifiers ever created must be stored and made available to clients. this number will always grow as the protocol processes more transactions cryptographer @gusgutoski has been thinking about this problem and has written up some ideas on applying tachyon, a scaling optimization for the zcash protocol, to shielded csv if you're interested in improving privacy and scalability for bitcoin payments, check it out!
