Unfortunately Cryptoalts.com shutdown because of the owner didn’t had any time to maintain the pool. I was the node operator of Cryptoalts and start re-writing the code to continue this pool.

After two weeks of coding / testing the pool is now open for open beta-testing under the name:

http://www.DutchPool.eu

DutchPool is a Hybrid p2pool multipool where you can mine POS coins like Blackcoin / Mintcoin and X11Coin. There is no registration needed just use your coin address as username and start mining. You can also get paid in multiple POS coins (Hybrid mining). Combine the address with a period (.) as username see our getting started page for more info. We have nodes online in Europe and Asia for Scrypt / X11 and SHA256.

We hope to see all Cryptoalts miners back at Dutchpool!
