the total are so big?
Do you mean total duckNote supply?
= 8 589 869 056 XDN
1. That is a
6th perfect number, discovered by Cataldi.
In number theory, a perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive divisors excluding the number itself (also known as its aliquot sum). Equivalently, a perfect number is a number that is half the sum of all of its positive divisors (including itself) i.e. σ1(n) = 2n.
http://en.wikipedia.org/wiki/Perfect_number2. That perfect number will avoid current Bitcoin alike denomination, imagine ~8bln Bitcoin market with ~8bln supply coin, like duckNote.
3. With duckNote supply curve ~79% of ever generated XDN will be emitted ~after 1 year since first block generation.
4. Also recently world population reached 7 bln people. Imagine, 1 person will own 1 XDN.
