Topic: Bitparking PPCoin Pool [closed] - page 3. (Read 22932 times)

There was a pool restart a few minutes ago to work around the ppcoind memory leak.

Have you considered making this a merge mined pool as well since it sounded like from other posts you could do merge mining with this coin as well so long as it is the primary coin?  Could prove interesting and I'd like to try that out for a little while at least depending on how pp matures.

The was a few minutes downtime just now while I restarted ppcoind to work around the memory leak.

A simple and effective way of doing this is just dividing the coins across separate wallets. The larger volumes you are dealing in the more wallets you would want to use.

Say you choose ten wallets, order them in terms of priority, 1, 2, 3, ..., 10.

Divide your current stock evenly across the 10 wallets. When you payout, use wallet 1 first, and then move to wallet 2, ...

When coins come in, allocate them across wallets in order to maintain a target ratio of 10% of coins in each wallet. i.e. usually you add to just wallet 1, but if the allocation in wallet 1 exceeds 10%, then divide the coins evenly across wallets 2-10.

All the bitcoin online wallets should be doing this anyway, so they can keep say, wallet 1 as a hot wallet, wallet 2 as an offline wallet, and wallets 3-10 locked in a safe.

How frequently the wallets need to come online to mine depends on how predictable inflows and outflows are. The less predictable, the more frequently you should bring wallets online to mine stake.

Setting the reserve balance does not change the ppcoind coin selection aglorithm. So even if I dynamically set the reserve to the level of the sum of all users selected reserves, withdrawals can come out of the high coin age balances unfortunately.

For passing on PoS rewards to users, I was thinking you could allow them to set a PoS balance value/% which will lock up that amount of coin for use in PoS, then you pay out PoS blocks proportionally based on these balances?  But seeing as the reserve balance feature is a config item and ?not dynamically settable? this may not be possible?

There was a couple of minutes downtime as I restarted the pool to workaround a ppcoind memory leak.

Yes moving funds resets the time. I'd be more inclined to add proof of stake incoming earning to the exchange first. An interesting approach would be a "proof of stake pool" which would really be an online wallet but optimized for ensuring fund movement minimizes effect on coin age.

I like the instant payouts, but would understand if you held my funds for 520 also.

*If* you do something around mining for stake, would it make sense to leave funds in the pool or your exchange or will it matter?  I'm asking because I think moving funds would reset the 30 day hold time required correct?

Good idea, I've limited it to the last 50 blocks.

The pool ran out of funds overnight, I'll top it up. The 520 confirmations is a killer

Edit: Topped up.

Just a quick suggestion doublec,

You might want to truncate the found blocks list in the pool data page, it is turning into an awfully long webpage..


Maybe just keep the found blocks in the last week, and a link to the rest of the list if somebody wants to see it.

Doublec - does the restart have anything to do with the Insufficient Funds to withdraw message I'm getting?

There will be a few minutes outage shortly as I update the ppcoind and restart to workaround the memory leak.

Edit: Restart complete.

When you mine on the pool you mine at difficulty 1 like most bitcoin pools. If you have a very high hashrate you might like to mine at a slightly higher difficulty to reduce network traffic. You can do this by following the instructions in the first post. Set your password to "d=x" where "x" is a number. "x" can't be higher than the current ppcoin difficulty as this would make no sense - you'd be losing money. You don't have to do any of this though if all you want to do is mine at difficulty 1.

PPCoin has the same difficulty for the proof of work blocks as bitcoin. As hash rate goes up, difficulty goes up.

The first post says the pool uses variable difficulty that you can set by using certain settings in the password field when you login to the pool...

I just don't understand it because it says to use any difficulty less than the current difficulty (which is in the thousands) and the example used in the first post was "8" as the difficulty. So I am looking for an accurate, detailed description of setting the difficulty for the ppcoin pool at BitParking, preferably for a minerd .bat

Can someone show me a quick example of how to set the difficulty when connecting and also show me where I can find the current ppcoin difficulty?

GRouPcoins are part of the Massively Merged Mining array of merged-mined coins, so if you used that pool you might do better than simply directly mining GRouPcoins yourself because your hashing power would get you a share of all the altcoins, expressed as (and converted into) DeVCoins, plus hey you never know it might even get you a fraction of a bitcoin eventually (as it actualyl is a p2pool, so you are mining bitcoins in distributed p2p fashion while also merged-mining the altcoins).

I added a new hardcoded checkpoint to BBQcoin recently since it is so low difficulty it could easily be 51% attacked again, my new version is in the BBQcoin directory of my sourceforge file-downloads site http://sourceforge.net/projects/galacticmilieu/files/

BBQcoin is like litecoin, it cannot be merged mined, even with litecoin, and aims to be CPU-friendly, which, right now, thanks to not currently being mined by folks using GPUs, it is doing a better job of in a way (that way being, hey with CPU you can still mine the stuff right now).

(After people attack a coin, it seems, they tend to go rest on their laurels afterward instead of keeping up the attack forever, so often after such an attack is a good time to get in and get some coins while they pat themselves on the back for having "killed" it...)

As to price, why, they are priceless!

GRouPcoin are traded on the Digitalis Open Transactions server; BBQcoins I have not set up there yet as I am waiting to see how they survive over a longer period of time before worrying about trading them.

RIght. About the only things still low enough in difficulty that a CPU will get you any are BBQcoin and, to a much less extent, GRouPcoin.
