Key is 2600 bytes for mldsa 87. Your fav icon is 10x bigger than that. Verify time and encapsulation is a few hundred microseconds for one verify and encaps. Your scary proportions are minuscule in practice. Even cortex m class can handle it. Not sure you have an argument when you put it up against a typical browser session. Plus 50% of all web traffic already uses pqc ciphersuites sooooo….

- scorpionfeet 6mo agoOh good point. Thanks. I don’t think about cryptocurrency at all. But yes the sigs are now 4.6k. Thats a huge block. Yeah that sure throws a wrench into blockchain. But the alternative is that blockchains based on ecdsa go away. Seems like a win to me. But I despise cryptocurrency.
