Datacoin can be a great repository of fun stuff, and amplify some great events!
We have something really awesome on our hands here

Both solution are good, so if somebody make fork and make those changes in coin, then coin can get new life!

It shouldn't be certainly block reward defined by diff in PoW chain.
About diff adjustment - maybe it could be done every block, like in a lot of today's altcoins?

Unfortunately I don't have cure for it.


But I don't think it is important problem.

Coin must be designed for constantly increasing popularity and difficulty and for long time distances.

Such variations of difficulty in scale of days (and weeks, may be month) it is a small noise. Sorry for this my opinion.

May be block reward must not be defined by difficulty.

If you have "cure" for "problem" I described, I assume that all miners of DTC would agree that must be first patch or fork.
Why? Because with fork we all get much, much more "elastic" network, and network that can sustain on random enter of "big miners". And after "big" miner left, we dont need to wait as we wait now, but to network stabilize in fey days. From that behavior all profits, small or big miner. Lowering difficulty will give us all chance to get many DTC, but as always in past, profit will get only big miners! .
Why? Because big miners on lower difficulty can mine 1M DTC in day or two, and small miner can mine in same time maybe 5000 DTC. Then big miner will go to only market, sell all, and dump the price. Small miner again get nothing. Since those 5K or 10K of DTC worth nothing.
I am not for ( if lowering difficulty will become reality) to lower diff below 9.5 . Because of algo in difficulty 9.5 you can mine 3.5 x more blocks then on diff 9.9
Even that would not stop big miners to grab big piece of cake, but they could not mine as can mine on difficulty 5. So they will dump price again but that dump will not be big. And last, with only one market, and with such low buy cap, DTC can live for years, or some can pump and bump this coin. But that is beyond our reach.

We want many good options and features.

But any such patches require hardforks.

It can be more simpler and meaningful not to make so much patches to dtc (it is difficult), but take anyone other already good coin and make fork by integrate datasaving functionality to it.

I know dtc code. Such integration can be made fast and enough simple.

But any way. Before trying it we need to make much preliminary work to define all needed features and options. It is needed to avoid any subsequent forks.

DATACOIN is fork of Primecoin, and as is DATACOIN has same "problems" as Primecoin. Algo like that has probably never been written for such big difficulty. Algo spec is 60 block per hours, so one block per minute. When in DATACOIN network only small rig with 5-6Khash start to mining, difficulty will start to rise . But when that rig left network, then problem is big: difficulty DOESNOT fall as was rise. And that is situation we have now. Difficulty is to high for this hash rate of whole network, and probably will need one or two months to get stable, to stabilize on 60 blocks per hour. That is main, and only problem this algo have. Could be fixed, I dont know, but it should be fixed

If you think about what you are saying, you would agree with me. Reward reduction with hashrate and diff rising is mainly, why miners have less rewards then they would get in normal halving process based on time, or without it.
That's why more miners = less rewards per block. I can understand it in PoW/PoS chain or PoW/PoS/PoB chain. But it doesn't make sense in PoW only chain.

Can't find any cpu miners atm, but there were cpu miners until this year...most of the links i can find are now dead, but i'm guessing with the correct conf any cpu xpm miner will work.
Just waiting for wallet to sync, but i'm pretty sure setgenerate true "cores" works fine

This is actually a really really good way to solve the current faux crisis.

If everyone dropped their hash by an order of magnitude or two - then in a month we'd see the difficulty approaching more favorable reward levels.

If someone wants to document a way to CPU mine DTC w/ just one thread (for the masses) - then we could have a Armistice agreement which benefits everyone. As the difficulty drops the optimization tunables would need adjustment every so often.

However, since the rational incentive would be for a greedy miner to run the 1080Ti rigs while everybody else sits at 1 core -- it'd be hard to expect the desirable outcome.

Anybody interested in a 90-day ceasefire on heavy mining?

edit: We could probably ask the pools to kick anybody with a hash > X to signal support for such an agreement.

OMG - Yawn Yawn Yawn

Look at bitcoin, back in 2011 1 block was 50 coins! Even i had 100,000 bitcoins back then...now just to tick the chain over takes half the power required to power a city, and to mine a block takes as much power as some small countries for 12.5coins. It also is not POS, so why does anyone mine it? Especially after the massive drop in the NewYear....because everyone wants to feel they haven't missed out YET, that they can be Billionaires too....never going to happen. If Satoshi hadnt taken his 99.91% of coins and burned them it would be virtually identical to DTC.

My point is, DTC is doing fine, it could do better, but it will not "die" overnight. It perhaps needs to evolve, but sorry, if miners have turned up too late, go mine 1 of the other 3000 coins.

As for there's no incentive to mine, so the chain will die...get a grip guys...i am keeping some coins alive with 1 thread of a Raspberry Pi...sheesh, its all relative to overall hashrate. The idiot who thinks we need a 6x1080ti rig just to turn the chain...OMG. I'd rather see 10,000 cpus or 750tis supporting this coin than 10, GPU rigs

The one thing i WOULD like to see thou, is for all miners of DTC to drop the 1080ti rigs, there is simply no need...for the devs to assist making sure the diff drops way back down....(not generally an issue with DTC, but many coins i mine seem to only ever increase, even when there are only 3 miners worldwide). Lets get the diff right back down below 5, then anyone with a single 750ti, or a decent modern cpu gets a fair chance.

I think the biggest mining issue facing DTC is its coin per day / profit vs power costs at the mo. I can't even mine 100 coins a day which would get me 3000 sats (£0.18) using £4 a day power....so i can only mine for fun or poss future investment.

So please stop moaning about how unfair it was, how unfair it is, and how unfair its going to be.
Stay on-board, jump off, or come back periodically (works best for me)...choice is yours really
I'm more concerned about a diff of 8.9 with so few miners....lets get back to 5, better still 1+ then we can all play

It's fine, that you mined for years. But it's not fair that rewards are much smaller with bigger hashrate. It's non-sense in solo PoW chain, because it nullify your rewards from participation in the network, and in fact weakens chain. In peercoin it had a sense - rewards were getting smaller, because it was a purpose, to have PoW negligible effect on chain, and have PoS dominated it. In PoW chain such as Datacoin or Primecoin, it's not a good architectural design, and discourages miners - which are providing main network security, and in fact the chain is more vulnerable to attacks.

What difficulty algorithm do you want?

Unfortunately dtc can successfully mining on GPU now.
I think anti GPU protection is more important.

It would be very interesting to find highly parallel algorithm with anti GPU protection. It is a little contradictory demand. But it is very interesting issue.

I am not specialist, I am not person how network is working, but I see that network has big difficulty with work. Since block reward time is 60 second, that mean network should resolve 60 blocks per hour. But if you count blocks in block explorer it is from 33 to 53 blocks per hours. So I dont know how your testing should affect network, but I hope network will survive!

Hi Team,

Basic etching tests using Apertus on Datacoin 0.15.99.08 mainnet are looking good so far.
The etching and the monitoring program are each using the latest DTC version and appear to stay synced during and after the data etch process.

I'd like to do bigger stress-tests but my testnets do not appear to be syncing.
This test is critical to see if the chain can handle repeated data entry on each block at a high load -- past chains have shown some instability after a heavy etch on two separate occasions -- knocking many wallets offline.
 
When we show some success on testnet, I will do the same test on mainnet.

Please share with me any peers that are on testnet at this time.
If you do not have one online, please boot one up and let's make this happen.
For proper development, we need a robust testnet.

Thank you for your assistance in this matter

Kind Regards,
The DataSea

Hi MarcusDe,

    Your assessment is accurate.

    The disagreement is not how some were mining but more so how others were not mining.
    The early adopters are being pressured to forfeit their investment in order to nullify the inevitable unequal outcome experienced by those who came late to the party.

Best Regards,

Oh well,

I can only say that I think that anybody could mine Datacoin thru those years like those who did.
And now some of you say it's not fair, because you didn't?
Some people had faith in this project whole time and supported it, while some of you joined few weeks ago.
Do you think that even paying for server to run pool 4 YEARS for those who want to mine was just for fun?

Sorry, nope.

No. Because it's not low hanging-fruit, It's very easy to underestimate the amount of effort involved.

Cheers

Why? I am confused. I think an app to take local file and store on blockchain is very useful. It needs only filename and data to be stored. To read back again only need block number where stored or to search through blockchain.

There is not an app that can drag-and-drop file from windows explorer to blockchain and save-as from blockchain to windows explorer. If there was such app I would use it. Also if there was such app nobody would make a second app and so first app would become universal and everybody could use it for same data.

Datacoin is not right for filesystem storage. Meaning storing of lots of files. Because blockchain has to store every file and so that makes expensive. If miners cannot store huge files then blockchain dies. If storing file is expensive then users only store small files like hashes. Example: Datacoin is useful for proving document existed before another document by storing hash even if file stored another place.

Datacoin is not useful for storing jpeg files if will cost many $$$. Hard disks are cheap. STORJ project is in good condition. Nobody chose Datacoin for store jpeg. Datacoin must focus on censorship-free storage like title suggests. Storing jpegs is not useful. Storing proof of jpegs is useful. Storing passwords to encrypted jpeg also useful if time of jpeg matters and jpeg not to be released until later time.

Example use of Datacoin: I want to backup bitcoin wallet. I encrypt wallet and add to Datacoin. It costs small amount. Now I can restore bitcoin even if my country hit by asteroid. But this is very difficult now because app to drag-and-drop files does not exist.

Someone had dumped large bag, but it's hard to get in DTC and get out. That's not the point. Point made by Verionum is imo, that coin was mined for several years, with huge rewards, but only "revived" a few months ago, where diff increased from 6.88 to 9.9, and rewards drop more than 10x. Not only those few miners have took most of rewards, but they have taken a very big rewards like 5000-10000DTC per day, which is lol. It isn't really good or fair, that PoW chain has ladder like rewards, it's like pyramid, where "leaders" take the most of it. It's bad. And it shouldn't be like that.

To change it, it would require hard fork, which most of the network wouldn't accept, because it would be against their consensus rules, and thus it needs to be created a new chain for more egalitarian distribution of it.
