hi @basti, nice to meet, and thanks for responding
yes! saw the anonymity-set paragraph in the best-practices piece. ++well-considered and nuanced. (btw, very grateful you’re advancing this, and i look forward to donating to L2BEAT in the next security round). the naive set can be much larger than the practical set once address reuse, timing analysis, and off-chain info are applied
i don’t think “Effective Crowd” replaces ‘Anonymity Set’ as the technical concept. the dashboard idea is to try to make one slice of that practical reduction visible. the challenge is that anonymity set often gets communicated via proxies like total deposits, total notes, pool size, tvl, etc
but the Q users should actually care about is more contextual
“for this asset, this amount range, and this time window, how many plausible alternatives exist?”
or more simply
“i want this amount of my asset to be private. will i blend in?”
so i think of it as
naive anonymity set → all possible candidates
effective crowd → the portion of that set that remains relevant after obvious filters eg. asset, amount, timing, entry/exit patterns
agree that on-chain data is only part of the story. but it’s the part that’s public, permanent, and available for anyone to analyze indefinitely, which makes it a useful place to start
to me, “Effective Crowd” is just a scoped anonymity-set estimate, and potentially a more intuitive dashboard label for regular users
