As Namecoin cloned the SHA256 method employed by Bitcoin, a miner’s hash could solve a block on either chain with equal probability. Of course, this equal probability demands both blockchains be of equal difficulty. Namecoin’s difficulty was driven far higher than its value by maintaining merged mining through linkage to Bitcoin’s difficulty.
But it seems a new type of pool has overcome the synchronised difficulty hurdle via some P2Pool wizardry, allowing full-powered merged mining across 1 scrypt coin of higher difficulty and 4 other scrypt coins!
Merge Mining 6 Scrypt Coins At Full Hashpower, Simultaneously?
Sounds too good to be true? Well, for a curmudgeonly, hobbyist GPU-miner like myself it’s not all good news:
The Drawback – your primary coin must be either:
Here’s hoping more primary coins are added to the mix soon, as none of these would be my first choice. I’d love to see Auroracoin or Anoncoin featured.
Your Merged Mining Selection
Whatever you decide on as your primary, you’ll be able to devote equal hashing power to the following minor coins:
1) Huntercoin, the coin that makes a game of mining. At least it does something new, although the game looks boring. Ticker HUC, currently #38 by mineable market cap.
2) Orgcoin, designed for merged mining with no maximum issuance, so another inflationary PoW coin without Doge’s community. Ticker ORG, market cap unavailable until it gets listed on more exchanges.
3) Pesetacoin, whose badly-translated website doesn’t inspire confidence. Ticker PTC, currently #65 by mineable market cap.
4) United Scrypt Coin, seems to be a simple clone designed around merged mining. Ticker USC, cmarket cap unavailable until it gets listed on more exchanges.
Potcoin is available as a wallet to add, but it’s unclear whether it’s fully supported as yet. No fee or other data is available on the ManicMiner site for Potcoin as yet. At any rate, its ticker is POT and it’s #79 by cap.
No choice here, as you’ll be mining all of them along with your primary. Hash attempts which prove incorrect for your primary will then be tried across your secondaries, multiplying the odds of finding a block by 4. This makes your mining far more profitable for no apparent downside.
How to Get Started with Scrypt Merged Mining
1) Register at ManicMiner.in.
2) You’ll need to give them an email. Google is creepy with a laborious registration process requiring your phone number (and soon, thumbprint and DNA sample), so I recommend creating a throwaway address at Safe-mail instead.
3) Hit “add worker” then “add wallet” and choose your primary coin’s wallet. You should create a new address in your wallet for the ManicMiner pool, for which you’ll need the wallet password. You do have a strong, minimum 12 character password which exists in the mind of you and your next-of-kin and on a non-degradable physical medium hidden in a disaster-proof location to which you control access, right?
4) Enter the info for your primary wallet. Then repeat the “add wallet” process for all the secondary coins.
You can mine multiple primaries but this will divide your hash power between them. Secondary coins will still be mined at 100% of your hashpower though.
5) If you’ve never mined before, you’ll need to download suitable mining software. The options are:
This Litecoin mining guide should give you a rough idea of what to expect from your hardware, plus the optimal settings people have discovered.
6) Copy the mining software to a suitable folder, then run the following commands (or create a batch file to do it for you) depending on your software:
Of course, the above user name (-u) is for my account and worker. If you’d like to reward my niceness in giving you this fine info for free, I would not object to your generous hashes, good sirs.
No password is necessary for this pool.
7) Be aware that ManicMiner will exact a 1% proportional mining fee and will also charge a small percentage fee for withdrawals. Set your automatic withdrawal period to a value you feel balances the fee against the risk of coins unable to received from the pool. The following table will help:
8) After all your hard work, relax as your GPU efficiently grinds away at multiple currencies. Have some tea and biscuits, light a cigar and enjoy a well-deserved chuckle at someone else’s expense:
I’m still downloading and syncing wallets for all the secondary coins, will update this article if / when I receive payments. Try out ManicMiner for yourself and please reply in the comments to say how it’s working out for you!
