I'm the developer of a multipool named Coin Catcher (www.coincatcher.net) and have been running a small scale beta for the last month.

The system itself has been really stable but there's a fundamental issue that is holding us back. With a pool hashrate of around 100-200 MH the variance and risk is far too great to take on coins such as DOGE / LTC. We risk not finding any blocks in a whole day which would mean no payouts to the users (it would be game over!). The only viable option is to mine smaller coins which give us consistent payouts, but often lower than some competitors.

We're currently running ahmedbodi's fork of stratum completely unmodified, using separate instances for each coin and port switching between them. I'd like to add a couple of new features and think it'd be best to work with someone more specialised in this area (my skills are more geared towards PHP web applications).

The 2 features I'd like added are:

1. For certain high difficulty coins we'd like the ability to proxy work to external pools. This will prevent our hashrate being the limiting factor and so will give us much more regular earnings. It's important that we still keep track of shares in our db so users can be paid out correctly.

2. Functionality to switch coins without disconnects. I.e. running just a single instance of stratum and switching coin deamons internally, using data queried from MySQL.

If anyone is able to help with this please let me know, and PM me with costs etc. Happy to pay in BTC / fiat / any other altcoin!

Cheers

[approximately 1 month]

After several months of development and testing, Coin Catcher is now ready to be released to the public. From day one, this project was designed to give users an easy and detailed view of their mining activities, and to be as transparent and profitable as possible.

We are running a beta period for approximately 1 month, in which fees will be 0%.
EDIT: BETA period has been extended - pool fees are still fixed at 0% (plus 0.4% trading fee)


JOIN NOW AT:
http://www.coincatcher.net



Key Features:

- Profit switching, currently mining over 30 different coins
- Full transparency - view your current balances for each coin, past trade history and mining details
- Variable difficulty (VARDIFF), giving lower variance to less powerful miners
- Clean and simple to use from both desktop and mobile
- Auto exchanges earnings to BTC
- Automatic payouts daily, for balances over 0.001 BTC
- Unique switching algorithm for increased profitability


More Details:

- Coins with a difficulty too high, or a trade volume too low will be skipped to maximise efficiency.
- 0% pool fees throughout the beta period, increases to 2% after that. Trade fees are 0.4%.
- Proportional payout; unpaid shares are carried over to the next round regardless of the coin.
- BTC payout addresses are tied to an account at registration and cannot be changed. This prevents coins being stolen if an account is compromised.
- Active and ongoing development. As we’re in beta you can expect lots of new features based on feedback from users.





Coins we mine:

Litecoin, GrandCoin, TagCoin, Diamond, Noirbits, CHNCoin, Franko, Spots, DogeCoin, DigitalCoin, Elacoin, Worldcoin, Bottlecaps, Luckycoin, Phoenixcoin, Cosmoscoin, Fastcoin, Alphacoin, BitBar, Netcoin, LottoCoin, CasinoCoin, HoboNickels, Neocoin, Anoncoin, StableCoin, Megacoin, Feathercoin, Orbitcoin, Emerald, Novacoin, Mooncoin. More will be added.


We’d appreciate any feedback or suggestions that you may have to help us develop and improve the pool further.

I’ve finished developing a new auto switching pool, and would like to run a short beta testing period before launching. The pool mines various scrypt coins and has been designed to improve on the other options available at the moment, particularly in terms of transparency and ease of use.

I’ve been mining there myself for a few weeks now and all seems to be working correctly, but I’d like to give it a trial run with more workers first.

If you’d be willing to help with testing, please send me a PM or reply to this post and I’ll send you details to access the pool.
