For anyone who's interested, a sneak peak at the next release of Darkcoin:

TLDR:

- Next release will go out in the next two days probably, I'm going with the community and calling it "The Onyx Release"
- It features mandatory, non-exploitable Masternode payments.
- Masternode payments are completely predictable now. I.e., if there's 2000 masternodes you can expect 1 payment every 4 days (divide the amount of nodes by the blocks per day to get your ROI).
- Masternode payments will go to 25% one week from release (non-manditory)
- Afterwards I encourage the community to find the pools still paying 20% and contact them to make sure they update their stratum before it's too late
- Masternode payments beyond that will increase to 30% in November, 35% in December and continue on until we get at least 3000 masternodes.
- Huge security updates to Darksend. It's much more robust and can take a beating.

How does the payouts work for new nodes coming online? They won't need to catch up to existing payouts, right?

Also interested in how this is done!

Even if there isn't a minimum 'age' for MNs to start receiving payments, I think the system will be pretty hard to game - you can't launch a thousand MNs without a million DRK, after all.

It's a true proof-of-service setup now. Each new node has a 1 in N (total number of masternodes) chance of receiving a payment each block. After a payment, they must wait N blocks to receive another one (give or take 10%). There's no room for gaming the system because it's using math based off of the proof-of-work to prove the node won, plus you'd have to wait 15 confirmations each time you moved money around and that takes from your profit too.

What do you mean there is no room for gaming the system?

Scenario: 3000 masternodes exist, I have 1. After 500 blocks, I get my payment. At this point I wouldn't be eligible for another payment for 2500 blocks. However, I could send the coins to a new address and restart the masternode, and once its confirmed I'm eligible again immediately, this time it takes say 2000 blocks, but after I do the same, new node. And finally a third time I get my payment after 1000 blocks.

Summary: 3500 blocks have been found. I have gotten 3 payments. Ideally, I should have only gotten 1 payment in this time - 3 would require 9000 blocks.

What am I missing?

Statistically they won't fare any better, actually a bit worse:

Code:

from random import randint

s = []

while True:
for i in range(1, 10000): #10000 blocks
if randint(1, 1001) == 1000: #1 in 1000 chance each block
print i+15 #requires 15 confirmations
s.append(i+15) #keep track
break

if len(s) > 1000: break #if we have 1000 simulated results, lets add them up

total = 0
count = 0
for a in s:
total += a
count += 1.0

print total / count

On average, it's about 1015 (1 in N, N=1000, plus 15 required confirmations) which is a tad worse then they'd make just by collecting the earnings

Plus check out the blocks between payments, this would drive someone crazy:

EDIT: There might be a bias to the newer node based on the fact that the algorithm is skipping nodes that don't qualify. Whenever it hits the newer node it would automatically qualify. In that case I could just introduce a greater minimum amount of confirmations before a payment to cancel out the bias.

The code you posted isn't how it actually will function though (in my understanding). If MN X is started now (block 100) and gets paid two blocks later (block 102) - they aren't eligible for another payment until block 1102 (masternode count=1000). However if they just restarted their node to a different address, they are potentially going to get a payment as early as block 117.
