Technical Discussion / Re: Network status

If you look at this account (FIM-YAZR-6U3M-DKAC-GCZTV) you might notice that something drastic changed around 17.Oct.2016. Two+ weeks before that (1-17.Oct) 42 blocks forged. The last three weeks (18.Oct-10.Nov) 12 blocks or 4 blocks in last two weeks. No change in setup or account balance. What's your math on that being fair?

Can't say for sure, but I'd suspect that it's been forking off and back on. There have been several disturbances in the network this autumn, including the pools, so that's quite plausible explanation. Maybe you could verify this from your server's logs. It's a good idea to occasionally check last blocks from the browser:
http://localhost:7886/index.html#/activity/fim/blockchain/latest
If that doesn't match lompsa.com (and several of the last ones are your account), you're probably on a fork (even though the server hasn't detected it yet).

Now there seems to be a quite healthy balance in the network, and a clear correlation between effective balance and blocks forged.

This is what I meant, a snapshot from this evening:
Account   Name   Effective balance   Blocks forged   Blocks/million FIMK   "Fairness" of the forged amount
FIM-6Y9S-3TVG-B28U-CG7MU   Krypto Fin ry forging support   17989122   738   41,02479265   1,168594929
FIM-JS7L-HU5X-XUTT-2GGQH   Warmach's Forging Pool   14873917   517   34,7588332   0,990108507

FIM-Q7FH-7V8U-7FJZ-8UE3Q      107949   4   37,05453501   1,055501781

Ideally, the "fairness" should be close to 1 for everyone, but because of (intended) randomness of the algorithms, occasional forking and/or downtime there are variations. But as you can see, even small forgers can get a fair share of the cake, if they can keep their servers up and running.

To support the small forgers, I decided to give 10 000 FIMK to each of those forging with less than a million FIMK. Beware, there might be similar rags in the future! And if somebody can convince me that they might start forging and commit to the task, I can make a donation up to 100k. Just private message me, and make your "business plan pitch"!

Your network monitoring has been really helpful!  :thumbup:
We owe you one for the FIMK activism anyway :)

Thanks, my pleasure.

Kinda hunch.

Sorry, but I really need the vulgarity there. Besides, "perstuntuma" is something a lot more definitive than just a hunch. ;-P

Now there seems to be a quite healthy balance in the network, and a clear correlation between effective balance and blocks forged.

For those who interested, the current ratio seems to be about 20-30 blocks forged per a million FIMK per day. If I calculated correctly, that means 0.2% daily "interest rate", i.e. 100-200% yearly profit. :cheers:

Now everybody start forging! :-D

Now that the situation is better, let's not focus on negative things anymore. ;-)

I myself just noticed, that I've been monitoring the network for quite a long time now, and have a good "perstuntuma" (I offer a beer for a good translation) about the overall status. I'll be posting my observations to this thread, if I find something noticeable.

What kind of instability does balancing the largest forgers with forging support cause?

As I explained, the forging support was too large compared to the pools and other whales. Now it's better in line with the largest pool, so let's hope the situation gets better. Still hoping for more members of the millionaire club to start (individually) forging, however...

Forging support switched off for now.

Or not? Still forging/forking and causing instability in the network.

While I don't know for sure, I think the wild swings in forging is because there is a smaller number of people and total FIMK forging. Before the HEAT buyout, we had like 30+ forgers and 200 - 300 million FIMK forging. Now, we have about 10-12 forgers and 60 million FIMK. I think we just need more whales!

Yes, that's what I have observed. There's a certain (approximate) ratio between FIMK held by a forger and the amount they forge. If there's one "too" large stakeholder (be it The Association, your pool or any other pool or individual forger), the ratio might get distorted, so that all/most of the other forgers end up in a fork. I know there shouldn't be 51% attack problem in NXT derivatives like FIMK, but the results are similar.

I'd say about half a dozen roughly equal sized whales (each one of them forging on different servers) should restore the balance. But if any of them is 5-10 times larger than any of the others, problems start to arise. (I don't have any exact calculations to support this theory, just a hunch based on the forging history)

Besides the whales, there are some small forgers, who seem to be able to forge the "correct" amount, at least when the overall situation is healthy. That's why I would encourage anyone, even with a small amount of FIMK to run a server and start forging!  :thumbup:

Could you tune down Krypto Fin ry forging support? Now it's forging a lot more than its stake suggests, so maybe there are forking problems again. At least all of the pools have dropped off from the list:

Good thougths, warmach. Thanks to the association for taking this issue seriously.  :thumbup:

Another reason to have more (benevolent and/or small) forgers?:

... or correct me if I'm the clueless one...

We have only 9 forgers. The network can't survive with only a few forgers. We need more people. I am thinking about closing my pool in the hope that people will forge and stabilize the network. If I do, I will give plenty of notice.

That is a good idea, because "... Also, a person with such a large stake in the network would be taking a big risk with their own wealth by attacking the network in a way which may undermine its credibility. ..."

I don't mean that you would be considering an attack, but showing that you don't want to have too much forging power is a good signal to the community.

See http://cryptorials.io/glossary/51-attack/ for details.

Now everybody start forging!  :cheers:

Sorry for the dumb questions, but I can't figure out which one of us is more clueless (or pretends to be). ;-P

This conversation makes me wonder that question more and more...

FWIK the network should be fine with just a single forger.

Doesn't sound quite distributed to me. :-o

Edit: Maybe a single forger is ok, but what if there are two forgers, who for some reason are disconnected from each other (but are connected to Internet or at least think they are)? Then a user manages to spend his/her entire balance via both forgers and buy two brand new Tesla Model S's. Who decides which one of the car dealers will have to refund/default and which vehicle the repo man *) goes after?

Would the network be more stable, if we had more individual forgers? Just a thought...

How are our forks doing? Any nice ones around lately  :P? (been receiving some reports of forking, but stuff looks quite ok at https://lompsa.com/#/activity/fim/forgers/latest )

I think FIMKers' Poolâ„¢ is still forging a lot less than it should considering the effective balance. I personally have had some forks, but have been able to resolve them manually by restarting the server and/or restoring from a recent backup.
