@gballet you have any opinions here?

hey
tamaghna from zeam here
do we know how much the private keys sizes are

here are some ballpark no (there are with the sha hash fn)

• (SHA3-256, $L=2^{18}$):**

• $w=4,: ≈ 560 MiB

• $w=2, : ≈ 1.15 GiB

so the idea would be to store the prf keys and generate the epoch based keys when required
PRF seed (32 B) + $P$ (≈32 B) → ≈ 64 B persistent secret

What have you guys implemented/thought about this ??
