The benefit is that every hash the miner does contributes to the total hash rate of both all currencies, and as a result they are all more secure.
Starting with a high-level explanation: The miner or mining controller in the case of pooled mining actually builds a block Basically the idea merged mining litecoin with gpu that you assemble a Namecoin block and hash it, and then insert that hash into a Bitcoin block.
Now when you solve the Bitcoin block at a difficulty level greater to or equal to the Namecoin difficulty level, it will be proof that that amount of work has been done for the Namecoin block. The Namecoin protocol has been altered to Isaac Kriegman 2 2. In other words, merged mining is part of the protocol, ASICs just do the math. The standard rules of merged mining still apply, of course. Why do namecoins have any value? Namecoins are used to register.
Chris Acheson 1, 10 When did merged Namecoin-Bitcoin mining start? The switch to merged mining is scheduled for Namecoin block At the time of this writing, the Namecoin network is on blockmerged mining litecoin with gpu more blocks need to be solved. The last 29 blocks on the Namecoin block explorer were solved in an average of Extrapolating from this, blocks should be solved in just under 30 days, so Will merged mining mine each chain as efficiently as non-merged mining?
Every hash you do will contribute fully to the hashing power of both block chains. You will have to do a tiny bit of extra work when you generate a work unit, but that's almost insignificant, and you only need to generate a work unit once for every few billion hashes you do.
You will generate just merged mining litecoin with gpu many Bitcoins as if you only mined Bitcoins and just as Does merged mining require clients to download both blockchains? Those running a miner against a pool don't. The pool operator would need both. As stated in the comments below, normal users merged mining litecoin with gpu the alternate system will not need the bitcoin chain but will need the alternate chain, and normal users of bitcoin will need the bitcoin chain but not the alternate chain.
Once the block is mined, nobody cares what other chains Detecting dishonest merged-mining pool. The only way to know for sure would be if you mined for the pool and you mined a Namecoin block for them.
You would find the particular header you had submitted as a share used as a solved, merge-mined Namecoin block. How is a side-chain merging back to Bitcoin chain protected against double-spend? Where are the side-chain mining fees? As Mikka explains, sidechains don't need to create their own currency, using bitcoins in the sidechain is precisely the point of two-way peg there's no reason why an altchain with its own currency, like say litecoin or ethereum, couldn't support 2-way peg and also become a sidechain though.
Also, take into account there's several possible ways to implement Will merge mining patch make Bitcoin network mining power available to anyone? The patch has no effect on the parent blockchain, it just allows the patched bitcoind to be used for mining on both chains simultaneously. Only the child blockchain needs to be modified in order to support merged mining.
There's no way for the Bitcoin network to prevent merged mining, even if doing so were desirable. Merged mining does have to potential NameCoin merged mining adds no more than 49 bytes to the size of the block.
Namecoin messages aren't stored in the merged mining litecoin with gpu block chain, instead the hash of the most recent namecoin block is stored in the Bitcoin block providing continuity between a potential hash and the Namecoin block chain. So yes it technically does "bloat" the Bitcoin blockchain but DeathAndTaxes 7, 1 25 Scrypt merged mining litecoin with gpu merged mining pools. Found a helpful post at litecointalk: It won't work because the aux work must be explicitly provided by the merge coin.
All of these coins cloned from Litecoin lack that code as Litecoin doesn't have it. As a result you cannot merge mine these coins. It is the same reason you can't merge mine Terracoin or Freicoin with Bitcoin. User 1 How does a miner insert the hash of a merged-mined alt chain's transaction into a Bitcoin transaction? A byte header cointaining: Number of entries in aux work merkle tree. Nonce used to merged mining litecoin with gpu indexes into aux work merkle tree; you may as well leave this at zero is The disadvantage of merged mining is the additional coin daemons you have to run in the background.
They all use disk space, memory, cpu cycles and bandwidth. A more annoying issue is that most of them are no longer maintained and have bugs.
You may find that they crash frequently - at least namecoind does. Haribo 5, 10 31 Which Namecoin block was the first one to be generated by merged mining? Yes, block was mined using MM, by slush's pool. AFAIK first Bitcoin block with merged-mining merged mining litecoin with gpu was cee20bc6ea5cfddbb11d34df blockalso mined by slush's pool. Functionality of merged mining for reference, from user ttk2 on BitcoinTalk: When you mine you generate hashes that may be the solution to the merged mining litecoin with gpu block, this is very very improbable per hash, its BinaryMage 1, 9 merged mining litecoin with gpu Are sidechains really new?
A side chain is a blockchain that runs parallel to the main bitcoin blockchain and can synchronize with it directly, allowing decentralized value transfer between the two chains. A user merged mining litecoin with gpu able to essentially lock merged mining litecoin with gpu a certain merged mining litecoin with gpu of coin on the main bitcoin block chain which then frees up an equivalent amount of coin on the side chain.
Vance Cagle 51 4. How merged mining litecoin with gpu block rewards claimed in merged mining? The point of mining is to secure the blockchain. Before you mine, you must compose the block you are trying to find a nonce for. That block will include a transaction to pay you. If you are merged mining Bitcoin and Namecoin, you do the following: This includes a transaction to pay you How does merged mining work on a technical level?
There's actually a very good detailed specification on the bitcoin. Essentially, what it comes down to is that there's some data inserted into the coinbase transaction of the parent chain. So, assuming, for example, that Bitcoin is the parent chain and Namecoin the child chain, anyone merge-mining would be using a coinbase transaction in Bitcoin Jimmy Song 6, 8 In the future it might be able to modify the patch to allow more generalized merged mining between any number of coins.
This is not a bad thing Quote from Gavin in the thread you linked to: I don't see how shared mining dilutes bitcoins. That's like saying "real-world What is needed to create a pool with merged mining?
After that, you need to build your pool server to communicate with it through Bitcoin API and handle everything else. Last part is not too Bitcoin-specific and will consume a lot of your development time I would know, I tried it Specific namecoin address in merged mining. However you may be able to work around this in one of the following ways depending on your coding ability. Monitor P2Pool logs and trigger script Watch the p2pool logs and when a block is found How to merged mine with getmemorypool RPC command?
Most of what you need is explained at https: The format of this data is explained at the URL above under "Merged mining coinbase". If, while hashing the
