In the meantime, pool is up with one dgm server running while I resolve these issues and attempt to bring the others online.

Also couldn't connect to the pool until a couple of minutes ago, seems to be back on now though, at least i'm currently connected to mmpool.bitparking.com:4333. Hopefully problems are fixed.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
A social engineering hack attempt was attempted on the bitparking server this morning. The attacker attempted to convince my hosting site that they were me, and successfully gained access to the customer service portal. They used this to raise support requests to gain access to the server. No access to the server itself was available through the portal and they did not succeed in gaining access to the server as I was able to communicate to the hosting provider about what was going on.
The attacker registered a domain name, "chrisdouble.co.nz", as part of the social engineering attempt to gain access. This domain name is not owned or affiliated with me. If anyone attempts to contact you regarding bitparking services you should be wary that this may be a social engineering attempt. I can be reached on the bitparking Bitmessage address shown at the bottom of the pool's main page if you want to confirm my identity. My GPG fingerprint is also available on the bitcoin otc and I can sign messages with GPG to confirm information if you need confirmation messages are from me.
Some bitparking services are currently disabled while I deal with cleaning up issues related to the attack and tighten some things up. Most notably the PPS servers are offline and traffic is being redirected to the DGM servers. The bitparking hot wallet is at the bare minimum needed to service DGM blocks as they arrive. My apologies for any inconvenience this may cause.
If you use other bitcoin services be aware that they may be targets of similar social engineering attacks. At least one other pool, BTCGuild, has had an attempt using the same method and you can read about that in their thread.
The attacker in my case attempted to pass off that they were the 'toil' or 'Josh Rogers' identity that was possibly involved in the OzCoin hack so it's possible these are done by the same party. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux)

Hi, doublec
You switched all to DGM ? I see than nothing was earned by miner during the night.
When do you switch back to PPS ?

Sorry, I have not read the whole thread. Does this pool share the tx fees with the miners?
No, it does not share the tx fees. The process of doing this is tricky for PPS pools that pay out before the block is found. I'm sorry to hear about the attack and well done on preventing it! Re: the above: Are you willing to reconsider, since you now have DGM enabled?

The process of paying transaction fees is almost as tricky with DGM. I don't know of any DGM pools that pay it - are there any? It's still on my radar to investigate though.

Can you explain the prolonged low luck? Over a period between Jan 17 to May 1, blockchain.com shows pool luck at 60 percent. Statistically this just doesn't seem likely. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FOGPxTj5.png&t=665&c=q-twxzkZ7fBpog)

While I can't answer probability for the luck figures: The sample size is VERY small (48 blocks). There's also no guarantee Bitcoinchain has properly credited all of bitparking's blocks (doublec could answer that though).

It doesn't matter. It was a pure PPS pool (before the DGM switch), hence withholding blocks doesn't affect you earnings. Now with DGM of course it would be an issue.

Guess I'm mining at backup pools until the pps side comes back. Always sad when a good pool can't stick to an easy to understand payment system.

The easiest thing to understand about PPS is "pool will eventually go bankrupt".

blockchain.info doesn't pick up all the blocks. You're better off using blockorigin. There's also the stats.csv which is the block file I provide for the weekly pools thread. The pool has had a bad run of luck, especially in the last two weeks. This is a major reason for providing DGM. I don't have the funds to keep a reserve of PPS going through the bad luck period. It does vary a a lot though. The last difficulty period I think I was about 1.4x difficulty overall. The period before that I was about 0.9x difficulty.

If you can provide the funds for the reserve I'll switch it on now.

I've thought of a few possibilities to bring some form of PPS back without needing large reserves. One approach might be to split the 25 BTC reward so that 5BTC is distributed via PPS and 20 BTC via DGM (or whatever split). A single share gets a PPS payment computed from the value of the 5 BTC and a DGM share at the value of the 20 BTC. At 5 BTC provided for PPS and a 5% fee the pool would need a 230 BTC reserve to cover that with a 1 in 100 risk of ruin. This provides at least some regular, no need to wait for a block, type of earning with a chunk that becomes available when a block is found via DGM. The split could be adjusted based on reserves the pool has. What are the thoughts of something like this?

Even with a split, given a long enough period of bad luck you'll run into unlimited negative expense for the PPS payments won't you? I'm not one of your miners and I know people like the simplicity and reliability of PPS. But my advice is to stick to payment models that don't put the operator at risk.
