See my message here for details on the closing of the exchange:

Recent events have shown that running an exchange is way to risky and stressful to me in the current alt coin climate. Prices have risen to a point where I'm not comfortable I can provide a reasonable level of service. To this end I'm closing the exchange and encourage all users to move to vircurex. The following details are on the exchange site:

2013-04-05: The Bitparking exchange is closing down. I've decided the risk involved in dealing with the current high prices for the alt coins has moved from the 'fun hobby' level the exchange originally started with and requires a more serious approach to operation. I've been in contact with the Vircurex exchange and I encourage all existing customers to move their funds and continue trading their.

The exchange will close trading Friday 5 April 2013 22:00 and new deposit addresses will not be able to be created. Trading operations will also be disabled. Withdrawals will be available for a few days after that at which point the exchange will close and all funds sent to their emergency withdrawal address. Withdrawal fees are removed during this period. Thanks for using the exchange and enjoy a better and more professional experience at Vircurex.

Pool closed, sorry. From the pool page:

I regret to inform that I've decided to close this ppcoin pool. With the large recent increases in PPCoin price and the variance of finding blocks with the ppcoin network combined with the 512 block maturity time it's become to risky for me to keep operating. In the last few days the pool has lost 10,000 PPC out of reserves and I'm not willing to fund out of pocket at the current prices. Thanks for mining here and I recommend coinotron.com or vpool.us. Withdrawls remain enabled for a few days and then I'll automatically withdraw to all user addresses.

CJDNS provides a virtual ipv6 address and allows connecting to the virtual ipv6 addresses of other nodes connected in the cjdns network. The traffic is encrypted and the real IP address of the endpoints are hidden. The real server IP is also hidden by the cjdns ipv6 address. I've added support to my bitparking pool to try it out. If anyone is using cjdns and wants to give mining through it a try:

1. Install cjdns from https://github.com/cjdelisle/cjdns
2. Connect to a cjdns peer. Possibly one from the public peer list or PM me for a connection to one of my nodes.
3. Point your miner to: http://[fc9f:ee0a:c283:c945:ede0:8a59:78e7:99d6]:16098. Longpolling also runs over cjdns.
4. Access the main pool website for withdrawals at: http://[fc9f:ee0a:c283:c945:ede0:8a59:78e7:99d6]:90/pool

This is an experiment and I'm interested in the performance of it. let me know your feedback if you try it.

[stratum+tcp://mmpool.bitparking.com:3333]

There's a thread someone started for this but I can't edit it for hash rate or features so I've started this one. The Bitparking Merged Mining Pool mines Bitcoin, Namecoin. IXcoin and Devcoin. Features of the pool:

• URL: http://mmpool.bitparking.com
• DGM at 1.5% fee
• Payout on found blocks enabled after only a few confirmations - no waiting for the full 120
• Miners can select difficulty level (see below)
• Merge Mining Bitcoin, Namecoin, ixcoin and devcoin
• Stratum support on stratum+tcp://mmpool.bitparking.com:3333
• Simple registration. Just set your username, coin addresses and mine.
• Getwork mining on port 80 available by pointing your miner to http://mmrpc.bitparking.com instead of http://mmpool.bitparking.com:15098
• Mining stats.
• IRC Channel: #mmpool on freenode IRC network
• Run by the operator of the first public bitcoin mining pool.

I've kept everything deliberately sparse. Coin addresses can't be edited once created (by design) but you can register a new username anytime with new addresses. This is to prevent unauthorized people modifying addresses.

Large hashrate miners can choose to set their own difficulty to mine at. To do this set your password to be "d=8" to mine at difficulty 8. Change '8' to any number less than 60,000.

As mentioned in the main i0coin thread,  now that i0coin supports merged mining I've modified my existing pool software to merge mine Bitcoin, Namecoin, i0coin, IXcoin and Devcoin. Payment is 'Pay Per Share' rather than the proportional system used by my other bitparking pools. Details at http://mmpool.bitparking.com.

There may be bugs in the i0coin merged mining implementation or the pool software so there may be a few ups and downs in the pool at this early stage as I stamp them out. Contact me via email (email is on the pool website) if you have questions/problems.

I've put a SolidCoin version of my pool and exchange software up so you can mine and exchange SolidCoins for Bitcoins. Pool is at http://scpool.bitparking.com and the exchange is at https://scexchange.bitparking.com.

I've started a Namecoin exchange where you can buy and sell Namecoins for Bitcoins: https://exchange.bitparking.com

It's pretty new, only a few days old, but has had a few trades put through it. I'd appreciate any feedback for features and reports for bugs.

I started a pool for mining namecoins. It uses standard bitcoin miners and is share based like other pools. Miners solve difficulty 1 shares and get a proportion of the generated coins based on their contribution. The pool takes a 3% fee and coins are available for withdrawal immediately a block is generated - no waiting for maturity.

Details are at the Bitparking Namecoin Pool Page. Basically you point your miner to the server at http://bitparking.com:9098 and use a Namecoin address as your username. The password can be anything. Withdrawals are only available to that Namecoin address. To withdraw, go to http://bitparking.com/pool, enter the address in the form and press the button. That takes you to your miner statistics. There will be a withdrawal button there if you have any coins.

Information on setting up a namecoin client to create the address you need can be found in my  blog post about namecoins

I got bitcoind running on the N900. It wasn't too hard. I had to build the right versions of libdb and libboost and make one minor change to util.cpp. The ParseHex function in util.cpp has code like:

Code:

if (c == -1)

'c' is a 'char' type which is unsigned so this comparison never does what's expected. Changing both instances of this to the following gets a working bitcoind:

Code:

if (c == (char)-1)

Where 'working' means it's currently downloading the block chain. I  haven't extensively tested it yet. Binary here if anyone wants to risk it:

http://bluishcoder.co.nz/bitcoin-pool/bitcoind.gz

gunzip it and run it from the terminal. The standard RPC commands will work with it running.

Update: 2010-02-04: The changes to ParseHex are no longer needed as they're part of the bitcoin source now. An updated build for the N900 is available here:

http://www.bluishcoder.co.nz/bitcoin-pool/bitcoind-b1a657.gz

This is built from github commit b1a657.

I've started a pooled mining server using puddinpop's remote mining version of bitcoin being discussed in the technical forum: http://bitcointalk.org/index.php?topic=1458.0

Due to high difficulty levels it will take a long time for a CPU based miner to generate a block and get 50 coins. By joining in the pooled effort you combine your efforts with everyone else in the pool. The server ensures everyone is working cooperatively so the average time to generate the coins for the entire pool is based on the sum of their hash values. The pool server then distributes the 50 coins based on the contributions of the people in the pool. See the technical thread for more details.

I've put a page up containing the latest version of puddinpop's software and instructions on how to connect to my server: http://www.bluishcoder.co.nz/bitcoin-pool/

There is currently no version of the miner for GPU's but hopefully one will be available soon. Currently there are 26 clients with a combined khash of 25,000.
