Technical Discussion / Re: Main FIMK node service interruption
« on: January 10, 2017, 07:40:17 AM »
Forgot to mention: I had to restore from a backup from December a couple of times on both of my servers before they started staying on the main chain.

This seems to have caused some instability in the network: for example my server and Warmach's pool have forked several times. Could you have a look, what might be wrong?

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"!

Donation round 2 sent. Let me know, if I missed somebody. Happy New Year!

General FIMK Discussion / Re: Forging Service - Anyone Interested?

The more I think about it, the more I think you are right.  One server can forge with multiple addresses, but each server has its own local blockchain.  What we really need is more individual blockchain (a.k.a. servers) so that there is a greater consensus on the chain and less chance of forks.

Well, I have a primary server that forges for the pool, but I also have backup servers.  Each backup server also forges in the event that primary server goes down or hits a fork.  If I have 3 servers running, I'm not sure it matters if I split the forging accounts among them or just use the pool account on all three.  In the end, I think it is how many server nodes are on the network, not how the forging accounts are spread out among them.
I think that besides the number of servers/blockchains, the "equality" of them is also important. If you split an "overpowered" balance to two servers, that should even out the "voting". But I'm on thin ice here, maybe Dirk or somebody can clarify...

One question I do have, If I have 3 servers running behind one public IP, do we get the stability effect of 3 nodes?  Or does it just act as one?
I've sometimes suspected that having multiple servers behind one NAT can cause problems, but I'm not sure if it was because of that or something else.

I'm not sure, if that would help. If I've understood correctly, the number of servers (and the distribution of balances between the servers) is more relevant than the number of forging accounts. If you have multiple accounts forging on the same server, wouldn't they all end up in the same fork*? At least the opposite is true: I have one account forging on 2-3 servers at a time, and the servers end up in forks independently of each other. And only the "correct" one is shown in lompsa.com, of course.

What might work better, could be that warmach and/or any other "too" large server split in two, dividing the balance between two servers. For a pool, it would require moving half of the forgers (balances) to another server. For starters, warmach could move his own balance forging to another (account and) server. Also the forging support from association could run on multiple servers (if not already running). What do you think?

*) I'm using the term fork here in a wider sense: any chain of blocks, regardless of the "correctness" of that particular chain in consensus of the network.

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-QLSC-282V-5GC3-8PJLX   Zero Pool   6946851   218   31,38112506   0,893894186
FIM-XP28-YFNT-ZCNU-GU8WN   Fitcoin   3383381   104   30,73848319   0,875588474
FIM-34B3-PWY5-TMHC-9JYW8      2914791   88   30,19084387   0,859988918

FIM-FSNP-9AKV-DN99-34SDS      627087   7   11,16272543   0,317971243
FIM-77P7-WE66-HF3Y-9JU6J      819386   6   7,322556158   0,208583674
FIM-8Z96-4U4J-34WT-34K2Y   Gunnari Liikkuvainen   178581   4   22,39879942   0,638031827
FIM-Q7FH-7V8U-7FJZ-8UE3Q      107949   4   37,05453501   1,055501781
FIM-3896-ZVLA-XKU8-C6XXG   Kati   102336   1   9,771732333   0,278348679
   Total   50076789   1758   35,10608478

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:
