Would it be possible for someone with 2116 Sig to kill the block chain when it gets to proof of stake?  

This is not my area of expertise, but if my numbers are within 4-5 orders of magnitude this is a critical issue.  

if interest is paid hourly, as has been stated, it must be recorded on the block chain.

Not sure interest will be paid hourly, where did you read that ?
I believe I read it somewhere on here.  Page 10 of the white paper actually says it is paid every 5 minutes.  

A 5 minute payout would be 0.0000004756 so 0.02102608 Sig per wallet, but you would only need 15,000.  15,000 * 0.02102608 + 150 = 465.3912

Main.cpp sets
Code:
nSubsidy = nCoinAge * COIN_YEAR_REWARD * 33 / (365 * 33 + 8)

From what I can tell it simplifies to "nCoinAge * 13689"  All the math is e-8, but if nCoinAge is the mature coins and it runs every 5 minutes then this is a 1400% return.  

Hopefully I am wrong.  

Edit: Fixed exponential.


I flipped the nSubsidy calculation around and for 5% return it would be 365.24242424242424242424242424224 payments, so daily payments considering leap year.  This would be the second functional error I have found in the white paper. 

So 43516 Sig used to create 4320000 addresses with 0.00007305 Sig each could flood the chain with interest transactions? 


Try to reach devs or something. I am also curious about this.

I'm also interested to know more technical calculation about this piece of code, as many other coin also apply same code on it.

I Actually contacted the signatumd (Main dev) and i got this awnser:
You CANT flood the network, there is a minimal ammount of SIGT that the address needs to be able to stake, and the minimal ammount depends from how much SIGT's are staking on the network, i am actually trying to find the formula for minimal ammount on the code but im not a programmer so...
