I would like to make some chain analysis tools available for free online in the coming months.
In my opinion people should have the right to access these tools without either the technical
know-how or a bill to some firm.
I would like to make some tools too.
Not for free.Let us begin competition between two approaches

If you are interested in it - drop me a message.
I think anybody reading this thread is interested. And I am all for competition. In principal, I would not be against a low fee to check for taint.
You might consider writing up your Tool, allowing either beta-testers or a freebie to see how well it works.
A free tool will be used more. And get lots of acclaim in the BTC/programming community.
Or perhaps you could allow 10 uses for some low fee...
