Namecoin merged mining
Merged mining or combined mining is a protocol that allows two different blockchains that share the same consensus protocol and hash function, to be mined together without loss of performance and maintaining a high level of security. Recommended Previous Content. What is the Consensus? What is Cryptocurrency Mining. A Around , a new mining model in which the same miner could dedicate himself to mining blocks in two or more different blockchains , a concept known today as merged mining o combined mining. Although block chains of any cryptocurrencies are completely independent and do not cross each other, there is a possibility that miners will use their mining power hash rate to create a valid hash for both networks.

Merge Mine
Merged mining is the process of allowing two different crypto currencies based on the same algorithm to be mined simultaneously. This allows low hash powered crypto currencies to increase the hashing power behind their network by bootstrapping onto more popular crypto currencies.
Two of the best examples of this are scrypt mining of both litecoin and dogecoin , as well as namecoin and bitcoin with sha This is quite a complex process. All the transactions for both networks are ordered and their merkle trees hashed out. The two blockchains are classified as the parent and the auxiliary blockchain.
The Auxilary blockchains merkle root is inserted into the extra nonce section of the parent blockchain — i. Bitcoin or Litecoin with Dogecoin and Namecoin as the auxiliary chain. In the case of Bitcoin and Namecoin , the difficulty is lower for Namecoin as there is less network power on that chain — i. The problem with this is that if a relatively large pool in the Bitcoin network switched to merge mining it could take a very large portion of the namecoin hashing power.
In case 1 nothing happens and the merged miner inserts a new nonce value and rehashes. In case two the miner has found a solution for the Namecoin network and propagates its solution throughout that network, if mining in conjunction with Bitcoin.
In case three solutions have been found for both of the chains and so a all the required information for confirmations is propagated to dedicated miners of both networks and the merged miner has won both Bitcoin and Namecoin or Dogecoin and Litecoin.

The merged miner finds a solution where the difficulty is too low to provide a valid hash and proof of work for either chain.
The merged miner finds a solution where the proof of work has been achieved for the auxiliary chain, but not for the parent chain. The merged miner finds a solution for that is greater than the difficulty requirements for both the parent and the auxiliary blockchains. Related guides. What is Multi-pool mining?

RSK: The Most Profitable Merged Mining Platform on Bitcoin
Abstract: In this report we examine merge mining on the Bitcoin blockchain. In the last year or so, on average each Bitcoin block mined contains around two commitment hashes from other blockchains somewhere in the coinbase transaction, indicating that most miners are conducting multiple forms of merge mining. There has been considerable growth in merge mining over the last few years and this may be of limited concern to some, due to the small potential security risks and increased mining centralisation pressure. Most of these risks could be mitigated away by blind merge mining, if these newer schemes are adopted. Merged mining, sometimes called auxiliary proof of work, is the process of mining two or more chains at the same time. Essentially the same proof of work can be used as assurance on multiple systems. This involves a parent chain and a child chain, when the child chain essentially inherits some of the security characteristics of the parent.

Bitcoin Stack Exchange is a question and answer site for Bitcoin crypto-currency enthusiasts. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. Does one solution fit all? 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.

Merged mining works by attaching additional information to the auxiliary chain block to prove that work was done on the parent chain. The class CAuxPow includes:. When a miner finds a parent block that is under an aux chain target, it submits the aux proof of work to the aux chain. Of course, this required a modification to CBlock::CheckWork in the aux chain to validate. The proxy translates these to a backward compatible work that is understood by existing miners and pool software.

N OTE: This standard is used by Namecoin , but new merged mining data should likely propose a new BIP to supercede it with something based on p2pool's merged mining. This is used to prove work on the auxiliary blockchain. In vinced's original implementation it's generated by calling the getworkaux RPC method on the parent blockchain client bitcoind and then the work is then submitted by passing it to the auxiliary chain client namecoind as the second parameter to getauxblock. In the below table, the shaded rows are the same as the standard block definition:. The current Namecoin client doesn't check this field for validity, and as such some AuxPOW blocks have it little-endian, and some have it big-endian. Say Alice created a Merkle tree, and it's root element is publicly available.

Jan 27 Reuters - Tencent Holdings Ltd HK plans to take DouYu International Holdings Ltd private amid disagreements over strategy among executives at the Chinese videogame streaming firm, two people with direct knowledge of the matter said. N were blocked by regulators in July last year on antitrust grounds. There have been differences among DouYu executives over whether to stick with game livestreaming as its core business or shift towards more profitable entertainment livestreaming, said the other person. That tension has not abated even after DouYu co-founder and co-CEO Zhang Wenming, who had favoured diversifying revenue streams, resigned last month, the person added.

Therefore I could not support Namecoin even if it works perfectly as you say it does. We're going to need a more environmentally-friendly solution to decentralizing DNS. As long as Bitcoin exists you can do merged mining with Namecoin. This means there is literally zero additional cost and impact on the environment for mining.

T Chief Operating Officer Marcelo Claure is in advanced talks to leave the Japanese conglomerate, after a fallout with founder Masayoshi Son over his pay, a person familiar with the matter said. Claure's departure is expected to be announced in Tokyo on Friday morning, the source said, requesting anonymity as the discussions are confidential. Executive compensation at publicly listed Japanese companies is typically capped at a certain level, as large payouts to top management in the country are frowned upon by investors.
