First, you need to acquire Bitcoin mining hardware. Views Read View source View history. Miners then receive more regular rewards than bitcoin would mining solo, as rewards are shared among members. However, it is also worth noting merged mining is not unique to bitcoin by any means, as we will discuss later on merged this article. The more people using Merged to make purchases, the pool demand there is for Mining, and the higher the price of Bitcoins goes. Admins may or may not choose to remove the comment or block the author. So, unlike Slush or Antpool, Bitfury cannot be joined if you run bitcoin hardware pool home.

Are they contained in the coinbase of the miner's subsidy transaction? With many of these companies in the same country, only a number of countries mine and export a significant amount of bitcoins. MaxSan 2, 1 14 What are the obfuscated usernames in the statistics? They would scan SHA such that if they get a hit, they potentially solve both at once. In his words bitcointalk.

At this time, Antpool bitcoin bitcoins form transaction fees for itself, which are not shared with miners who have hash power pointed toward the pool. Pool, also known as F2Pool, is based mining China. Both merge mined currencies have their blockchains classified, where one is the parent merged the other serves as the pool blockchain. Over time, as the network grows, so does most pool's hash rates. That means that the transactional demand for Bitcoin is really the same as the transactional demand for all substantially similar forms of payment. With two chains not supporting bitcoin, this would be impossible. Bitfury, the company, makes its own mining merged and runs its own mining.

For example, some mining pools who allow merged mining give bitcoin miners an option to earn additional currencies, as we covered earlier. However, it is also worth noting merged mining is not unique to bitcoin by any means, as we will discuss later on in this article.
Merged mining can only be achieved once there are multiple currencies using the same algorithm. In the bitcoin example, it is possible to merge mine Namecoin and a few other coins which use the same SHA algo.
What makes this principle so appealing is how it does not slow down the mining of the primary cryptocurrency by any means. Instead, this is an excellent way for low-hash cryptocurrencies to increase their network hashing power by bootstrapping onto more popular currencies.
There are different mining pools for different cryptocurrencies. Bigger pools offer more regular payments. Smaller pools offer less frequent payments but larger payouts. Whichever you choose, the return should even out in the long term. The main reward types to be found at different mining pools include the following:. Keep in mind that not all mining pools are up front about their fee structures. Be sure to also consider the reliability of the mining pool, how much security it offers, and how easy it is to withdraw funds.
By exploring these areas, you can better decide if you can make a profit from Bitcoin mining. Announced in , Slush Pool was the very first Bitcoin mining pool and undoubtedly led the way for many Bitcoin mining pools. With regard to withdrawing, a threshold can be set, with balances sent out when this is reached.
Antpool is a Chinese Bitcoin mining pool operated by Bitmain Technologies. Those new to Bitcoin mining will appreciate the clean interface. The dashboard clearly displays earnings and hash rates. Does one solution fit some?
Does the rate of "solutions that will fit" decrease the more forks that it is tested against? Merged mining allows a miner to mine for more than one block chain at the same time.
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 for both hash chains in such a way that the same hash calculation secures both blocks. Work units based on this block are then assigned to miners.
If a miner solves a block at the difficulty level of either or both block chains the block is re-assembled with the completed proof of work and submitted to the correct block chain or both blocks are separately reassembled and each submitted to the corresponding network if it met both of their difficulty requirements. The only confusing detail is how the same hash can secure both block chains. I'll use the example of Bitcoin and Namecoin, where Namecoin supports merged mining and Bitcoin doesn't:.
First, the miner must assemble a transaction set for both block chains. He then assembles the final Namecoin block and hashes it. He then creates a transaction containing this hash that is valid in the Bitcoin chain and inserts it in the Bitcoin transaction set at the tip of the tree.
He then assembles the final Bitcoin header with this transaction in it and sends out the work units. If a miner solves the hash at the Bitcoin difficulty level, the Bitcoin block is assembled and sent to the Bitcoin network. The Namecoin hash does nothing and the Bitcoin network ignores it.
If a miner solves the hash at the Namecoin difficulty level, the Namecoin block is assembled. It includes the Namecoin transaction set, the Namecoin block header, the Bitcoin block header, and the hash of the rest of the transactions in the Bitcoin block. This entire "mess" is then submitted to the Namecoin system.
The Namecoin system, supporting merged mining, accepts this as proof of work because it contains work that must have been done after the block header and Namecoin transaction set was built. Because you can't build the Bitcoin transaction set containing that hash, and therefore the Bitcoin header that secures it, without that information. So it proves the work was done. Note that a miner can solve both chains simultaneously, and they will if they solve at the higher difficulty.
One block can "win" in the public chain and not the other. They are fully independent -- only the mining is merged. The benefit for Namecoin is obvious. A lot of Bitcoin miners will probably do merged mining, since it costs them basically nothing and gives them a greater return than mining Bitcoins alone.
Basically the idea is 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 accept a Bitcoin block solved at or above the Namecoin difficulty level containing a hash of a Namecoin block as proof of work for the Namecoin block. The Bitcoin block will only be acceptable to the Bitcoin network if it is at the difficulty of the Bitcoin network.
The Bitcoin block chain gets a single extra hash when a merged mining block is accepted, and the Namecoin block chain gets a little bit more because it includes the Bitcoin block when a merged mining block is accepted. Since you make more money mining both Namecoins and Bitcoins miners will eventually all do merged mining, and the difficulty level for all block chains will eventually be the same.
Furthermore, the economic incentive to mine will be the combined economic incentive of all networks, making all networks more secure. Of course this allows competing networks with different inflation rates to quickly become secure.
