Raising ringsize Wownero v0.5 #19

double it... 44

44 is a happy number, and 43 is a lucky number.

Both look good to me.

42 is the the answer to what is the meaning of life, the universe, and
everything though...

In testnet, the size of a transaction with ringsize 44 is around 6.8066 kB and the fee 0.02091 (with fee per byte). The current transaction size with ringsize 22 is around 4.6504 kB and fee 0.0328506.

@SamsungGalaxyPlayer thoughts?

Honestly there's little research to support that 44 provides better protection than 22 except that it's a higher number. We haven't gotten to flex our muscles with such large ringsizes yet haha.

At such large ringsizes with bulletproofs, transaction sizes are not a huge concern (but they are a slight one). Instead, Wownero should compare the verification times for transactions of different numbers of inputs. Eg (can you fill in this chart?):

Verification times

Ringsize	1 input	2 inputs	3 inputs	5 inputs	10 inputs
22	---	---	---	---	---
30	---	---	---	---	---
35	---	---	---	---	---
40	---	---	---	---	---
45	---	---	---	---	---
50	---	---	---	---	---

Second, thought, there is really no compelling reason to increase ring size other than the assumption that "bigger must be better". This issue could be reopen again if anyone wants to push for a bigger ring size.
