Bitcoin Forum

OK check out

EDIT HOW are users finding the DEV patch... is it working, do we have to wait until tomorrow to finds out???

It is still swinging about as far as I can SEE

I have looked at the exponential averaging

http://en.wikipedia.org/wiki/Exponential_smoothing (http://en.wikipedia.org/wiki/Exponential_smoothing)

but I think we really need the "Triple exponential smoothing" version of it.....to work

I am also not across the exact nature of the 1/2 ing in 10 min blocktimes.


It still seems that BTE is ok relative to TRC as BTE had a HASH attack higher than TRC and it all went away after a few hours...not days.

IT may be that until asics are wide spread {cough cough BFL} that this may be a problem for all sha alt chains...

I just don't have the time right now to go over the whole code and maths.....it would take me a few goes to get a smoothing code out...and I suspect that this maybe what we are experiencing here....

Edit:: fixed up the commenting out of the material functions...

I have as best I can updated the main, I have taken out the BROKEN target system, and replaced it with the BTC one

this is in main.cpp

I have left all changes and commented my changes

(not the usual delete code, so you can see exactly what I am doing)

I had to delete the "ema" in the function call

Can some one try/check this

this should fix re-targeting


I would much appreciate Sunnyking or Tradefortresses input or any one else's input

can we name it trollcoin?  and make it pirate themed cuz terracoin.org sucks ass

spacegoat, how old are you? I'm trying to figure out how you haven't realized yet that no one cares about your idiotic trollcoin idea

Question I have is, if TRC uses this what makes it different from the more established coins BTC and LTC? Terracoin's difficulty adjustment is supposed to be it's unique selling point...

This is just an interim to make TRC stable while it is figure out what the timing should be...by the DEV

the TRC has a different payout rate as well...see DEVS info

Also BTE shows that Coming Closer to BTC is viable itself.

BTE is coming close to TRC in value and is only days old


I am only doing this as a temporary interim (unless the community decides to adopt it), because DEV would not.

you wouldn't understand.  it would be a meme based coin.  the epitome of open sourced intelligence.  troll-face would be the meme.  it would be the don't give a fuck coin that works the best... and is actually fun.  and not so technical on the face.  just wham bam easy. simple.  keep the technical stuff under the hood.  

you could probably figure out why I am still stoked, if you saw the conversations going on in my inbox.  my original meme was kind of harsh.  but I've gotten some enthusiastic responses about the idea.  and I still like it so until you cut me down in a way that makes me even consider your opinion is valid I'm gonna continue running with it.  I have a vendetta of sorts.  

............................

I'm learning about bte's retargetting and what I've found is that bte is still vulnerable to 51% attacks.  

jubalix, it appears BTE recovered in 3 hours in comparison to TRC's 4-5 days, but its also a much smaller network, are we certain using btc's retargeting will solve this?  can we get more opinions on this, I am not familiar with forums, but sunny king and trade fortress seem to have coding legend status, if we could have them peer review your work jubalix,

I got nothing but energy, and I'll raise my class a bit and be more presentable with promoting the fork.

No BTE  had larger hash set against them than TRC did and recovered

If I recall correctly TRC had the equivalent of 6% of the Bitcoin network. I can't find my source for that, but thats what I remember.

BTE had >10%

I understand completely. That's my whole point- the entire trollcoin idea reminds me of something an angry 15 year old would come up with over losing some money. I can empathize with the fact you lost half of your TRC equity, I lost a lot myself. The difference (I think) is I know alt coins are an extremely volatile market and I'm prepared to lose everything. I'm that confident my entry point is +EV.

I respect your ambition and energy, I just think it could be put to better use then trollcoin or whatever this meme idea is. Perhaps try to improve the original TRC and recoup some of your loses. I'd certainly appreciate that.

OK i have worked my ass off here all through the small hours of the night lets all get together and see if this thing works

This seems like a good short term solution to fix TRC.

I hope everyone adopts this until the Dev can figure out a more permanent fix.

so terracoin is getting through 11 blocks a minute.  last time I checked. 

jubilex, you get any reviews from anybody?  any updates?

Difficulty 313116. They fixed f'all in latest release.

TRashCoin  ;D

wait for blocks and stuff to update check the network diff its gone down

???more detail please

but it was maddly osilating???


or is it all smooth again?

according to what i've seen on the difficulties its gone anywhere between 4000 and mid 30000s

so still maddley going around

Anyway we have a patch here ready to go, if anyone needs it or at least the basis for people to uptake it if needed very quickly

so this acts as an insurance for TRC

I've seen it between 5800 and 313k. It's still madness unfortunately.

http://cryptocoinexplorer.com:3750/chain/Terracoin
In the span of 10 minutes we see it go from 16738, down to 297, and up to 42477

Oh, crap, it's my mistake, it's devcoin's difficulty, TRC is on 26900

Sorry :(

And 30 seconds later 42400

ok well push for adoption of the patch

I mean...bte is 1/2 of TRC right now!

Could be wrong but I don't see why this would be needed....  The retarget algo seems to be working perfectly given the fact that you have asic miner(s) who think toying with an alt chain is more profitable than direct btc/btc-merge-mining .....  it ramps up quick and accordingly when they hop on and back down to normal levels for everyone else when they leave so the network keeps running instead of the previous stalling... you're keeping someone's asic off of btc more and they are not damaging the system in general, unlike before where the whole chain was taking hours to process a single block.....

The only real fix for the asic is not adjusting the difficulty algo, but changing the mining algo altogether.... many people have asked for a scrypt merge-minable coin, maybe fork that off but I don't see how BTC's diff algo will possibly defend against asic miners hopping on/off without leaving the chain hung for weeks/months before it can recover....

I've been watching the TRC block chain and yes the difficulty is swinging madly, but the coin is still working.  yes there are some minutes where some asic somewhere gets through a 5 or 10 blocks but it goes back smoothly to MOVEMENT.  transactions aren't stuck indefinitely, and not too many coins are flooding the market, and supposedly his algorhythm gets smoother over time.  and in about a hundred blocks supposedly the ultimate fix kicks in.  and if he has figured out asic invulnerability, TERRACOIN WILL HAVE MADE HISTORY. 

so for whatever this difficulty adjuster is, I give the developer props for being able to handle asics so far.

but I am still going to try to convert him to turning terracoin into trollcoin.  he might not be pleased with what I have done.

If I end up leaving terracoin alone I do want to birth trollcoin.  the money trolls prefer... worldwide

The problem as I'm seeing it from a mining perspective is that it looks to be killing the pools so its really only ASICs/GPU farms mining it because of the difficulty swings. Coinotron took theirs offline and multipool is having huge amounts of invalid shares due to the difficulty changing.  Which may kill mining in the longrun

That's all nice and shiny, but...c'mon, a difficutly adjustment with every single block?
How do people calculate their outcome on that?

And I'm not even talking about making any profits here, break-even-mining would be enough for a start,
but if I start my mining-rigs now, on a difficulty that at least pays my power-costs, it might not pay those costs anymore in 2minutes.
So I actually have to check the difficulty every block, 24/7, to shut off the rig when I can't afford the donation anymore.

TLDR: Seems like this mandatory update finally killed TRC

you think it killed it.  or just changed how mining for it works?  because if there is something out there hashing out its blocks, transactions will be processed.  there might be no mining pool possibility, but something out there is mining it.  and if I'm not mistaken, if an asic or gpu farm gets on trc and jumps off, there is a 10 minute adjuster that will divide the difficulty in half.

it seems wild and crazy, but I think he might be onto something.  I sold my TRC  but I don't know that I'm convinced that its actually dead.

Well, if there actually would be a economy, people that actually USE the coins, instead just mining for profits, I might even think about donating my resources (like other people are donating them to BOINC or such) for the good cause.

But that's not the case with TRC, people just mine it for profits, it doesn't have an actual purpose in itself and that's why I'm wondering how people calculate their outcome on a chain, that switches its difficulty with every block.
When you start mining at difficulty X, you might break-even, or even make a tiny profit, but just 5-10minutes later that might change and you're mining at a loss, donating resources and power to a more or less useless coin.

What's the point in that? Who's gonna mine on a chain like that and what's their incentive?

On BTC for example I have about 2weeks in advance that I can calculate on and choose to keep mining, when breaking even or making a small profit, or shut the rigs off when mining at a loss.
On TRC I have not 2weeks, not 2days, not even 2hours, but 2minutes!

I can see how that would be frusterating for a miner.  so the people mining all the terracoins are like gpu farmers and such then?  asics...

and they just mine for profits and feed it right into the exchange...

your frusterations mining TRC i can sympathize with, but I don't see how that means it will be the death of a coin, maybe the end of TRC being mineable by pools..

to the asics and gpu farms messing with trc: stahp!

It doesn't have anything todo with pools,
it kills mining in general and that's essential for a blockchain.

well the way it looks to me.  is if all miners "die" and nobody wants to mine it, the difficulty cuts in half every 10 minutes a block isn't found.

so theoretically if nobody mines it, some joe with a laptop could process block chains at difficulty of 1. 

so I am not convinced that this fix kills mining yet.  please fill me in.

Yeah, sure and once only joe mines on his laptop there's probably noone gonna hop on with a couple of GPUs, or even ASICs to "51%-attack"  (which is then more like a 99%-attack) the chain.

Totally secure network!

not to mention that the coins will be next to worthless if most everyone abandons it.  The ASICs will too at that point because the exchange rate of the coins will plummet

Just 20 min ago difficulty was 1.46K, then 2.1K, 3.11K 4.67K 7.47K, 11.5K, now 18.2K 
I've seen it do this over and over .. get up to a 35K or more then start over at really low difficulties.

ok I am starting to understand thanks dudes

does anybody know what he's talking about, I guess this temporary fix difficulty adjuster thing is going to self deactivate on something like 103792



https://github.com/terracoin/terracoin/issues/33

and then maybe it will be better to mine on? 

it seems like the developer is actually somewhat competent.  but he's trying to pioneer something that's never been done.  so tomorrow or the next day we should be on 103792... and its either going to flop or stabilize...  most would bet on it flopping.. but I sort of hope the 51% attack vulnerability issue for altcoins gets fixed so I can implement it in my new coin, trollcoin.  the best coin evvarrr

Im trying to solo mine this for the shit turd fun of it...
While Im solo mining... I get like 70% reject rates on found blocks =( this normal?? =(
This happens when theres a good 30 seconds between blocks on either side of my found one...why is it being rejected?

Im just pointing cgminer to terracoin-qt and have the terracoin.conf properly configured.

how do you solo mine it ?

TRC doesn't look good at all, this is what dev posted earlier today:
