[CLOSED] Massively Merged Mining

[gnpeer]

Are you running the latest p2pool release? http://screenshooter.net/9331790/mlxtbtf

And is there any chance of tutorial how to extract devcoins from btc address on windows or on-line wallet like https://blockchain.info?

[markm]

I had pulled from git just yesterday or the day before, bt since you asked, I did a git pull again:

Code:

So no, I evidently was missing the last couple of days of updates to the github repo.

Thus I have halted p2pool and restartedi t so make sure it actually uses the latest changes.

The way that I exported a private key from a bitcoin wallet and imported it into a devcoin wallet was with the python script pywallet.py

EDIT: I wonder what that new tag thing is about in the git output. I wonder if it is hinting I might not really be getting the latest code just by pulling. NOrmally pull works but I don't know what tags are about; the other day I had weird problems with luke-jr's version of PPCoin due to him using a branch, which I am guessing is not the same as a tag...

I guess the scrypt won't help due to lack of working devcoin client.

What operating system are you trying to compile a devcoin client on?

What operating system are you trying to compile a devcoin client on?

-MarkM-

Noobish windows.

[markm]

Well it is based on bitcoin code that compiled on windows so there is no reason it should fail to compile on windows. Maybe someone who is used to windows can help you with whatever specific compiler or linker errors you are getting...

Then too once you do get it compiled, I believe there is still a bounty avalable for anyone who provides windows binaries...

Well I don't have any code for doing this yet so this is somewhat improvised, done manually.

I have based it on the TeraHashes (of "area") shown on the "month" scale of p2pool's graphs page.

I figure if I only do it once a month hopefully it will not be too much of a burden and I can look into automating it somehow in the meantime.

Transaction fees in DeVCoin are pretty large, I have to check exactly I think they are a thousand times as large as in bitcoin but I wasn't sure so for now figured on not paying out totals less than 50 coins (in case fee is 50 whole coins; I think it is certainly 50 somethings.)

Code:

This looks like pretty reasonable set of calculations and if others agree then I will likely do same again at end of the month.

Any comments/suggestions?

Are namecoins being merged mined? Does groupcoin have a 35,550 generation rate and/or a value 6.6 times as high as devcoin?

[markm]

Namecoins are difficult enough that we have not found any blocks yet. Groupcoin is easy enough that we find lots of blocks.

Everyone stopped mining at the end of August, September I have been mining alone.

I guess Massively Merged Mining is not a popular concept.

Once ASICs start coming out dedicated hardware accumulation specifically for the purpsoe of Massively Merged Mining will begin, but it looks like reaching a point where all the blockchains waiting in the wings will be able to come back out into the open could take a while.

Not being out in the open does not seem to have hurt them though, they seem to be doing quite well for themselves so maybe being a P2P blockchain is over-rated; few of the "altcoins" seem to be doing well in fact so maybe "going private" was actually very advantageous.

I had only three miners in October, each joined the pool for only a very very brief time, one of them not getting any actually valid mining done just errors.

It isn't really worth my while to run through all these calculations so I guess I probably should hope no one comes along at all during November as this is pretty silly to bother spending time on.

But here are the figures anyway:

Coiledcoin        600   -    470 =    130 *    0.00000000 =      0
Devcoin         55004   -  20000 =  35000 *    1.00000000 =  35000
Groupcoin       244050  - 151200 =  92850 *    0.72987012 =  67768.44064200
I0coin           3696   -   2736 =    960 *    0.37662337 =    361.55843520
Ixcoin           1440   -    768 =    672 *  105.37766233 =  70813.78908576
Namecoin           50   -      0 =     50 * 2145.45350649 = 107272.67532450

Thus DeVCoins = (TeraHashes / 1060.0301) * 281216.46348746

=================================================================================

I do the figures by hand, and obviously there is no point bothering to develop software to to do it since there is no demand for the service.

No point developing software for doing the books of a service that no-one actually wants.

Siince we do it using p2pool anyway maybe that actually makes sense, since really p2pool is intended as a way to avoid centralisation thus basically to avoid the need for pools. Anyone interested in massively merged mining should just do it themselves I guess.

Notice I accounted the coiledcoins as being of zero value. There are no exchanges for them and most folks consider them dead and if not well hey I guess the pool can use them as its cut of the wealth.

Trying it out, but bfgminer is waiting most of the time. Tried it with and without lp.

[markm]

It took something like 12 hours to get machine upgraded to Fedora 17 from Fedora 16.

Whenever using pools you should always have "failover": backup pools your miner(s) switch too during downtimes of main pool(s).

Sorry about that but now I have three machines here upgraded to Fedora 17 and can start to look into splitting stuff up across multiple machines so not everything will have to go down at once when the current single main server machine goes down for maintenance upgrades etc.

Actually the machine itself was not down 12 hours, but the latest bitcoin from github switched over to a new type of database for its blockchain and for some reason or lack of reason decided to download the whole blockchain from peers instead of grabbing it from the old-stype-database copy that was already present.

Thus the pool as unusable for many more hours than the rest of the stuff on that server.

I do not know why bitcoin does not convert over the old blockchain when it upgrades like that but oh well it has a new format blockchain now so should be okay now despite constantly spewing warnings about being an experimental version. (It is that new, right from top of the github repo.)

All of the coin daemons had to be recompiled too before they would work with all the new libraries that came with the new version of the operating-system.

This pool is now closed, due to lack of demand/use.
