You can also do this with featherwallet, just get the download link from getmonero.org so you don't click on the phishing site.

If I understand your question right, I think you're looking for the inverse cumulative distribution function (a.k.a. quantile function) of the Erlang distribution.

The random length of time to mine the next block has an exponential distribution with rate parameter 1/t. The length of time to mine n blocks has an Erlang distribution with shape parameter n and rate parameter 1/t.

The Erlang distribution is a special case of the Gamma distribution. The Erlang distribution's shape parameter must be an integer, but the Gamma distribution's shape parameter can be any positive real number. We can use the Gamma distribution if Erlang isn't given to us by our calculator.

You would compute T in the R language with:

qgamma(p = p, shape = n, rate = 1/t)/n

The results of this simulation match the closed-form computation:

t <- 120
n <- 15
p <- 0.4

set.seed(314)

mining.times <- matrix(rexp(n * 100000, rate = 1/t), ncol = n)

mining.times <- rowSums(mining.times)

quantile(mining.times/n, probs = p)

qgamma(p = p, shape = n, rate = 1/t)/n
# Divide by n to get the mean instead of the total

A little off-topic but I guess proton called Monero a shitcoin so it's a little tiny bit on topic ;)

I was wrong, I didn't consider that their attack could drain badly coded DNM wallets by double-spending withdraw transactions.

Yeah sorry, I had not considered draining market wallets as an option. Thanks for the pentest, it greatly pushed FCMPs and high-throughput research forward!

This attack highlighted several issues that have been addressed. The biggest issue was wallets not automatically raising the default fee which led to transactions getting stuck for hours. Without the bug, you would have paid 2 cents instead of 0.5 for a transaction and it would have been confirmed at regular speed.

Next time please keep it to a more on-topic community.

And already awarded, which honestly surprises me way more lol.

Cool site!

Note that it's still on stagenet. Mainnet testing is supposedly going live in a handful of weeks.

It's not in the !monero sidebar but in the Monero.town instance sidebar. Not sure if you can even see it on any mobile app if it isn't your home instance.
