[ANN][MOTO] Motocoin

[HunterMinerCrafter]

DOH, a third problem with my patch; it could truncate the mantissa of the target when it masks in the 14 TT value bits, and end up misrepresenting the target as 0. (In the compact representation.)  This would have the nasty effect of terminating the chain. (No block could be mined with an intermediate map hash below 0.)  We could either simply always set the low bit (15) in all cases, or we could set up a second bignum type which accounts for the missing 14 bits of precision.

I really don't understand how to start the bot(
I can't compile it, because I don't know how..
And can't start the compiled version cause I have only 32bit Ubuntu..

Heeelp)

I don't think anyone else has 32 ubuntu. Maybe you should upgrade, if your computer supports 64 bit.

[e1ghtSpace]

Can someone please tell me how to compile the bot. I have the motocoin-qt compiled but I don't know how to compile the bot. I installed 2 Linuxs for this and I really don't want that to be a waste.

You also need to compile motogame under src/game/ and put the resulting binary next to motocoin-qt.

I use a different makefile for src/game/ and have not built his bot as is.  I tried merging his patches into my bot code, and have mined for quite awhile with his patches but have never hit a block with it, so I'm guessing something went wrong in the merge.

maybe it's a good idea

What command do I use in terminal?

Code:

make -f build-linux.sh

This?
Edit: I used ./build-Linux.sh
But I get errors.

Code:

Error: ID10T

What command do I use in terminal?

Try just `make` by itself.

You might have to merge the patches into a clean copy of the motocoin source and build with the original, "stock" makefile.

This isn't really the best venue for learning how to use build tools.  If you're running into problems you should search around some linux support forums, read man pages, etc. and keep this thread for things specific to motocoin itself.

Can you please release this compiled version?

No problem https://github.com/minim1ner/motocoin-bot/releases/tag/1

This version doesn't seem to sync very well.
It skips between being synced and syncing with the network.

{The last few pages}

Sorry for posting all of my errors everyone. I probably should have just PMed someone.

This is probably related to m1ner's getblocks patch.  Try removing it.

You'll need a broad variety of skills to be successful as a miner... your fun is probably only just beginning.  Plan to learn a lot. 

[HunterMinerCrafter]

I've updated the gist of my patch with the fixes for the issues I brought up earlier.  This seems pretty stable, now.

It's Ok, that's means it is ready.

[e1ghtSpace]

Ok, somehow I managed to compile the bot. When I launch it, the screen is black and then it just disappears. Is that normal?

Edit:
That's... just great.....

Nice spelling

So, to fix the buffer overflow, what type of variable do I need to change for which variable? (like double, int or float) Or do I need to do something else?

[HunterMinerCrafter]

Ok, somehow I managed to compile the bot. When I launch it, the screen is black and then it just disappears. Is that normal?

Pretty much.  Rendering anything would just slow hashing down.  Arguably, even bothering to take the time to run the GL window events wastes cycles that could be spent searching maps or interpreting the physics interactions.

Again, these are topics that are outside the context of this thread.  Let's keep the discussion on Motocoin itself, not how to generally compile/instrument/debug/recompile/run/profile/optimize software.  There are plenty of other forums out there for learning such things.

If you don't know, and/or can't figure out, how to do all of this stuff yourself then you'll need to have patience and wait for a more readily accessible ecosystem of tools to become available.  Mining a brand new, very experimental coin (with an entirely new and different mining paradigm, no less) is not something you should expect to be able to "just pick up."  Add to that the fact that your only tool is a crude and unpolished miner, that was really only released in a form intended to be illustrative for other developers, and you're looking at a pretty difficult endeavor if you're not prepared with an appropriate skill set.  If you're not ready, willing, and able to maintain your own bot code (and I mean literally implementing/tweaking the AI algorithm(s) involved) you will have to accept that you will be perpetually "behind the power curve" and likely will not have much opportunity to be competitive.

e1ghtSpace, this bot has some bug, as I already said it doesn't work for me on win nor on linux. Maybe it worked for its creator by accident because of undefined behaviour.

HunterMinerCrafter, I looked at your patch, hard to say how good it is. As I understand it will not affect current bots because they generate 10 seconds replays in 40 seconds so there is no deficit, right?

I ran it "as is" for quite awhile and never hit a block.  I also re-merged portions of it into my testnet bots, with some modification, and it did eventually find a block.  I certainly wouldn't expect a non-developer to be able to make it productive.

HunterMinerCrafter, I looked at your patch, hard to say how good it is.

Yes, I've been running experiments with it under a local testnet with (somewhat heavily) modified rules.  The loss of precision in the compact representation is actually a little noticeable, so I may want to improve that.  However, from a "securing the network from time warp type attacks" perspective it does seem to do the job.

As I understand it will not affect current bots because they generate 10 seconds replays in 40 seconds so there is no deficit, right?

This is ostensibly correct. It is important to remember that the actual intent of this patch has nothing to do with "beating bots" and everything to do with securing the network so that it can scale safely.  However, even without warp occuring there will be a very minor impact on the bots in two ways.  First, once the extra target does kick in (setting the secondary target to the max 1-bit collision value) it will require a trivial minimum sha512 hashing (2-4 rounds of sha for each map) in any case, which will have a very slight impact on map iteration time, and thus hash rates.  Second, it will create direct motivation for botters to not "naturally warp" the chain creating a deficit for the next round, so rational bot operators will likely modify their bots to not submit any blocks before they age to TT, which will also lower their efficiency.  (I do not expect all bot operators to be entirely rational, however.  Some will be aggressive/greedy with their bots, speculating on a higher future price, and will not ever block withhold even when given such incentive as less future work.)

The network is in an "unexpected" state right now, where human mining margin has increased on its own, but overall coin production is lower.  I suspect that this is a sort of natural correction phase, possibly related to the recent market activities, and possibly created out of a side effect of the established bot miners preparing for the impending competition.  The miners (and market speculators as well?) are probably still feeling out how to best handle this new mining scenario.  (There are really a lot more chain factors to consider than with most any other alt, including HUC!)

I've run some tests on overall impedance to bots.  In an experiment today I gave half of the network the ability to "instantly" generate a bike solution once the work deficit challenge rounds were paid, and had the other half of the network playing solutions constrained to "human speed."  So, basically, this simulated what would happen under the circumstance where the bike challenge was "fully broken" with some ideal solver.  In the worst case, the subsidy collected by "humans" was about 22% compared to without the patch in the same scenario where it became virtually impossible for a human to ever grab a coin at all. (Even if one did somehow the bot side could have ofc just arbitrarily forked their coin base out of existence, since they could instantly rewrite the chain via warp without the patch in place, heh.)

Also it has occurred to me today that if we ignore my earlier Median fix patch for now, we can launch the secondary target patch without requiring a hard fork on the network itself!  Old clients will run into issues with the game/replays and will need to be updated to human mine with, so we may want to consider a version increment in the headers to prompt user updates, but otherwise as long as the majority hashing strength switches over within the same round we should not need to hard-code a fork point, I think!
