00:11:35 <DataHoarder> It's not optional privacy
00:12:21 <DataHoarder> It depends what the QC opponent has as well. 
00:23:23 <br-m> <kiersten5821:matrix.org> @yushanren:matrix.org: i think every transaction on chain right now will be deanonymized 
11:10:27 <br-m> <yushanren:matrix.org> I did some readings about this topic. FCMP++ is not about PQC, but the proposed PQC algorithm CSIDH is in research. With Quantum computer, it can decrypt private key if public key is leaked. The public key is nowhere to find on chain. However you cannot count on FCMP++ to prevent quantum computers. Based on old blocks onchain  [... too long, see https://mrelay.p2pool.observer/e/867I5JELWmJ1b2hD ]
