I gathered some data to try to answer two questions about AP mining:
Did the introduction of AP mining cause a lot more people to start using Tornado?
If it did, were the new people using it as intended, or were they just interested in getting TORN and not in anonymity?
So I wrote some code that counted how many Tornado.cash withdrawals were done each day, and also counted how many were right back into the address that made a deposit.
Here is a chart of what that looks like:
It looks to me like AP mining didn’t have a big impact on the number of people using Tornado.cash (usage was growing before AP mining started).
And it looks like it DID attract some people only interested in mining TORN (but not as many as I expected-- the red lines on the chart).
Raw data in a google spreadsheet is here: TornadoUseData
