Interest - You can't mine Aero, but you will gain % interest on the number of Aeros you sent. Think Bank of America Cash back program*
Tax - To reducing hoarding, there will be a taxation on currency sitting within wallets, this will then be redistributed as an interest % for the interest on transactions.
There will be a Tax bracket, similar to how an economy functions, i'm not ready to reveal the logistics and %s.
NOTE : This tax is an insignificant number. If you make a transaction, within X amount of months, you will not be taxed. This is also based on income size.
Transactions and Block-chains - When you log into Aero, you are connected to all the block-chains and database of every transaction immediately. Your wallet will be used a resource to help secure and process transactions. (more soon)
Are there any protections against users creating multiple wallets and sending transactions back and forth between them in order to earn interest?
There are a few measures to protect against this scenario.
The more transactions you make, in a real-world scenario the better the system is to recognize a legitimate transaction and award a higher %. There will be a Tier system, in which your account will be scored on. I believe the tiers go all the way up to 5.
Let's say, you and a friend want to make several transactions and collect interest for each other. So you send each others accounts balances back and forth to try to generate the interest. Well, you will only collect interest on 1 transaction in a 72 hour period to X account.
If this happens every 72 hours, the system will recognize a falsified transaction and not award any interest. This will help protect against companies generating interest on every transaction, while paying employees. Just an example.
In general:
You will not be able to collect interest on more than 3 transactions, totaling 10,000 Aero in a 24 hour period. You can make 1 transaction for 30,000 aero and collect a larger percent interest or several small transactions. None the less, the interest is insignificant.
This is for a tier 1 account (which i'll discuss later)
a Second countermeasure is where the transaction is coming from. We can screen for proxies and IP addresses, since this is an online built system (The easiest check)
I believe there are about 8 other checks in order to gain an interest or Taxation. I've glimpsed at the code and it's intriguing.
This is a small sample of the countermeasures of the system. When we fully reveal interest and taxation, we hope most people will be very pleased on they way we proceed about it.
Let me clarify anything, keep asking questions if you have any.
