It is topic for old PoW chain, some users continue support old GPL.

[minerja]

Interesting,

Have just downloaded wallet and chain from links above

If i click on .exe no issues, no connections, but no issues
if i create the .conf you have given....wallet opens, gets 1 connection, and then closes after 1 second

Any ideas?

oh, and the blockchain zips fails to extract....tried it on 3 diff pc's

zip file is OK, just download and extract.
wallet closes or connection closes?

It looks like maybe the current difficulty is simply too high for a new block to be created within two hours by the small number of CPU cores that are actually mining it?

Maybe someone with a GPU or an ancient tiny Scrypt-Jane ASIC (if such things exist) could wean it down in difficulty enough that the few CPU cores the supporters are able to muster will be able to keep the blockchain moving?

If there are such things as ancient tiny Scrypt-Jane ASICs maybe it'd be worth aquiring one powerful enough to keep the chain moving? Though in theory we only need to move it enough slow enough for its difficulty to drop into a low enough range the current family of CPU cores working on it will be able to keep it going?

I guess it is always going to be vulnerable to someone popping in now and again with massive hashing power to drive up the difficulty then running off again, but oh well not much we can do about that except eventually get the value up high enough to attract a lot of hashing consistently.

I just checked my http://MakeMoney.Knotwork.com/ site and see I haven't yet documented GPL on the HORIZON network; the doc for GPL on the Stellar network is http://makemoney.knotwork.com/stellar/gpl/

I see some wallets on old (pre-hardfork ) version

74.127.196.143
185.121.25.4
195.201.10.19

Please update to v2.9.1

To @markm
GPL now on minimum difficulty. Just always it was very hard in mining.
Scrypt-Jane ASIC never exist.
You need use any old video card for mining (only memory size important, best use with 2-4 Gb)

[markm]

I think I am all out of video cards, my last one blew up, along with the motherboard it was on, back when I tried to use it to mine Darsek.

I can't really spare any more motherboards even if I were to find a secondhand GPU on Kijiji.

I guess I need to somehow figure out how many CPU cores it takes to make a block every two hours or less at minimum difficulty.

Or just hope someone who DOES have a GPU will mine it.

You need start own stratum server https://github.com/scificrypto/Gold-Pressed-Latinum/releases/download/v2.9.1/GPL-stratum.zip
and get blocks regardless  2 hours limit.

[markm]

I do not seem to be able to make that work.

For starters trying to use the update externals script to get the externals does not work since this zip's contents do not seem to be a git repository (no .git file) so git refuses to work with it.

The first external it demands when I tried to run it was stratum, so I foind a different, multi-coin stratum-miner on github grabbed that used its update externals to get the externals and copied over the stratum external, but trying to "install" or "setup" that failed due to some kind of mismatch of a "distribute" thing that made it unable to create an "egg".

I tried both the instructions in the stratum external, both for developers and for install from a package, both bombed out unable to create an egg.

(I am using Ubuntu 16.04 LTS still on all my machines.)

Do you have any idea how many CPU cores it would take to be able to somewhat-reliably find a block within two hours? I think I have somewhere around 20 or so on it right now and clearly that is not enough.

I take and modify for GPL stratum server from here 5 years ago.

Hi Guys,

Just fired this up from scratch for oldtimes sake. (completely fresh install)
All went fine, BUT stuck at a particular block

Any ideas?
Thanks J

No miners - no new blocks, sorry.

GPL Classic is trade-able on the Stellar platform, along with various other of the Sci-Fi coins and also GPL2.

See http://makemoney.knotwork.com/

It should also be on the HORIZON network, see horizon section of that same website.

I do not recall off-hand whether there are any offers on the HORIZON network yet but on Stellar I just put a bunch so I know there are some there.

We could use a few more people devoting a CPU-core (or even a few) to mining GPL Classic because currently there are not quite enough to keep a block an hour being mined, and as soon as an hour goes by without a block all the mining wallets become unable to mine for some reason (a bug or something?) so we need just enough miners to keep the blockchain moving at one block per hour.

It might be that just one person using a GPU could manage that, but since seemingly no-one is using GPUs why drive up the difficulty making it more expensive for everyone? If we can do it just with CPUs we might as well do so.

GPL is now part of the Galactic Milieu game.

Since trying to use "exchanges" to "discover" the values of game-currencies has proven a very awkward and unreliable process, we prefer to divide a "treasury" by the number of coins minted to arrive at a value. So for the last few years various groups wanting to adopt a currency as their national currency or clan currency or species currency or whatever in the game have been quietly putting together "treasuries" of "reserves" toward that purpose. Lately a number of these treasuries have been put into use.

Thus here are the Latest Rates values of many of the Galactic Milieu's coins and assets, expressed in GPL at that calculated value of a GPL coin:

BBQrate=.00001336
sBCErate=13.47986047
sBCIrate=1.85991832
sBMCrate=1.93641560
sBRFrate=2.15982350
BTCrate=5884.44768986
CDNrate=1.29825244
CLCrate=.00114595
sCMCrate=1.89946284
sCRFrate=38.87412590
CZBrate=.00838414
DVCrate=.00010748
sDVCrate=87.80570290
FBXrate=.00420013
sGDCrate=92.73821482
sGFCrate=330.86403948
sGHCrate=23.71870524
GMCrate=1.80958018
GPLrate=1.00000000
GPL2rate=.78451882
sGRCrate=102.22229594
GRFrate=2.90393272
GRPrate=.01137360
sGRPrate=.46622000
I0Crate=.04314888
IXCrate=.04386671
LTCrate=39.40226172
MBCrate=2.47325728
NKLrate=.04532637
NMCrate=.41091097
SPICErate=1.03940483
TBXrate=.00420013
UFCrate=.00110712
UKBrate=1.22300669
UNSrate=1.29017828
USFrate=.00045811
XGGrate=.00262456



Note that GPL is by this method more valuable per coin than is GPL2  despite the problems that GPL (aka GPL Classic) is having keeping its blockchain moving.

That is because the value is based on the treasury and the number of coins not on whether anyone has lately bothered to make the blockchain move. The blockchain does not actually NEED to move for people to trade stuff on the HORIZON and STELLAR platforms, so unless you want to trade coins that are on the blockchain, as for example to trade on-the-blockchain GPL for on the HORIZON network or STELLAR network GPL tokens, the blockchain can just sit right where it is without affecting this method of coming up with a value for the coins.

(There are, partly because folks have not been mining GPL, less GPL coins in existence than there are GPL2 coins in existence. Thus even if both treasuries have equal total value, which they perfectly well might depending upon how the Ferengi divvied up their funds upon splitting into GPL and GPL2 camps, GPL divides its treasury by less total coins than does GPL2 thus currently arrives at a higher value per coin.)

Is anyone interested in trading GPL (aka GPL Classic) against Stellar Lumens (XLM) or DeVCoins (DVC) on the Stellar platform?
