Rank_{i} = j \sum e^{- \frac{1}{σ} zap_age_{ij}} \times zap_amount_{ij}

$i$ is the item and $j$ is the zaps on item $i$

$σ$ controls the half life

Probably just drop the zaps that are older than some preset amount too

we can weight it by the exchange rate at the time ~lol

NONO

Because then the units of the rank would be in dollars not sats!

the exponential decay pretty much zeros out old zaps contributions anyway, so the only different it'd make would be the computational speed of filtering out old zaps vs. extra calculations by including them

Computation is what I was thinking about, but I didn't think about the computation of filtering

Nice! That's roughly what I arrived at as an accumulator for making a resurface decision. When it exceeds a dynamic threshold, I'd move forward the effective_age.

I've been a little hesitant to give full control to recent zaps alone, but I'm probably just FUDing myself and it's worth experimenting with.

Edit: It also hadn't occurred to me to use it raw like this until your comment. I think this would make it worth being in the back catalog.

I think the difference would be pretty marginal. 95% of zaps happen in the first 48 hours. At least this gives a chance of good old posts to resurface.

We'll see. I think if posts are able to resurface and people can earn rewards for zapping them when they do, then we'll see more zaps on older posts.
