[9 TH] Bitparking Pool, DGM 0%,vardiff,stratum,Merge Mining

[Mike Hearn]

Hi there doublec,

Would it be possible for you to select and document your block policies as other pools are doing, please? See my post here:

  https://bitcointalk.org/index.php?topic=149668.0

It means selecting size of blocks to create and then setting some flags on your node. BTCGuild is currently making 750kb blocks and OzCoin has moved to 500kb. You are still on the default of 250kb. Larger blocks mean transactions confirm faster because we don't run out of space.

Miners will appreciate knowing pool policies so they can select a pool that they agree with.

Interesting; so the higher size will likely create longer confirmation times tho?  or just increase doublec's hardware/software requirements?

Higher size means transactions confirm faster (for everyone) because they're more likely to be included in a Bitparking block.

More transactions/traffic means higher requirements on nodes, but Bitparking is already paying the bulk of the cost of those transactions because the signature checking happens when they enter the memory pool anyway. So it shouldn't make any noticeable difference.

I'll document them later today when I'm not mobile. I put the block size at 500kb when I first read your post btw. I briefly tried 1000kb but the load on the pool was a bit much. At least it highlighted some inefficiencies I need to fix!

Merge mining is operational again.

Hello,
I contacted you by email to change my withdraw address, I no longer own the current one (12q7dcMpU1bkzo3GTExkiu6vb6AMvzc2Zb).
I don't have much there, 0.31 BTC, but it's still a lot for me.
Could you change it to the one in my signature: 1LgRjArkFGHt5tyud78diNAepF2ZTPhsYT.

Thank you.

I'm sorry but it's not possible to change withdrawal addresses on the pool. As it states on the registration page: "These addresses cannot be changed once you've accepted the form below. You'll need to register a new userid if you want to change them."

How did you come to no longer owning the existing one? Can you contact the current owner to retrieve the funds? Do you own the private key for the address, and if you do, can you sign a message I give you with it (to recover funds)?

What happen with PPC mining and exchange?

502 Bad Gateway

PPC pool is up. PPC exchange is down for bitcoind and ppcoind upgrades. Both of which require re-processing the blockchain.

You have a PPC pool???

Yes. http://ppcpool.bitparking.com.

Pool is down while I investigate an issue with bitcoind not receiving new blocks on the network for the past few hours.

[doublec]

It looks like a wider problem with blockchain forks. All bitparking services are down while this bitcoin issue is investigated.

[doublec]

I've rolled back to an older bitcoin client as suggested by the bitcoin developers and have enabled mining again. Withdrawals are disabled until the issue with the bitcoin blockchain is resolved.

you rock!  I ironically just updated to 0.8... was that a poor choice on my part?

You can still downgrade if you haven't deleted your old blockchain data. If you're not mining though you should probably just shut the node down until the situation is resolved and we know which is the 'one true client' to run. If you're mining solo, mine on a 0.7.2 client. Bitparking is now running 0.7.2.

Withdrawals on bitparking pool are re-enabled and service is back to normal for the exchanges.

I am testing stratum support. You may see your miner jump to the stratum protocol if it supports the redirection via the X-Stratum header. The server is stratum+tcp://mmpool.bitparking.com:3333. The stratum server is not currently merge mining but it is paying out the alt coin PPS portion from pool reserves. Please post any issues about the stratum usage here.

Remember to set your difficulty for mining by setting your password to "d=8" to set the difficulty to '8'. Change '8' to an integer number for the difficulty you want to mine at. If you don't set the difficulty it will default to 4 on the stratum server.

Thanks for always looking for new opportunities.  Can you post a link or explain in a couple words what advantages "stratum" would bring to your pool?

A description of stratum is here. It basically provides a more efficient way of receiving and sending work from/to the pool that the 'getwork' and longpoll protocols. For ASIC miners and other very fast devices this will cut down on bandwidth and make more efficient use of their machines. There should be less stales.
