Ok. But explain to me why, when I start your client I have 2 targets, respectively two BTC addresses, at each scanned range. One is for #64 but the other for what? For your database?
Be fair, man!
I'll tell you what you do with the database created with the help of the contributors. You will have access to those addresses and if ever they are used you will steal from those wallets everything. This is the truth, no matter what you say and how many bullshit say about your pool.

The second target is used for proof of work.  The private key that is found when scanning the range is used to find the range marker in the DB to mark it checked.
They are located at random locations throughout the individual ranges.
