P2pool + Bitcoin full node + merged mining installation script

This script downloads and installs bitcoind, p2pool, and other coins for merged mining. It is designed to be installed on a fresh installation of Ubuntu 14.04. It can be used with either the Server or Desktop editions. If you want to find out how it works or make sure it's not doing something dodgy, I urge you to just read the file! It's plain text (not a binary executable file), well documented, and about as clear as I can make it.

How to download

If you are using a graphical interface, simply log on to this page, right-click the link below, and save the file somewhere you can find it, like in your Home or Documents directory.

If you are using a text-only interface (such as a terminal, or ssh'ing into the server), use the following command to download the file:>

wget http://bitcoin.kyros.info/install-merged-mining.sh

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-256.

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.e. Bitcoin or Litecoin with Dogecoin and Namecoin as the auxiliary chain.

As the information of one chain’s set of hashes has been incorporated into a superfluous part of the other blockchain then a proof of work can be considered to have been achieved...

From Namecoin DNS

Tell me how it works in easy words!

"Merged mining works like this, you have two totally separate block chains, they are not related in any way nor does either contain any data from the other. When you mine you generate hashes that may be the solution to the current block, this is very very improbable per hash, its like a lottery where everyone generates tickets until someone finds the winning one. Normally you make tickets and check them against the Bitcoin block chain to see if they are the solution. With merged mining you create a ticket and check it against both the Bitcoin block chain and the Namecoin block chain, Bitcoin and Namecoin know nothing about each other, they are two totally different lotteries with different winning numbers, you just sent a copy of your ticket to both. Since you are sending the same ticket to two lotteries you increase your chances of winning one or the other. No Bitcoin data goes into Namecoin no Namecoin data...

Bitcoin started the cryptocurrency revolution. Bitcoin was first introduced in 2009 after Satoshi Nakamoto published a paper about the new digital currency the previous year. Being an open source protocol, many alternate cryptocurrencies followed bitcoin. These alternate currencies are better known as Altcoins.

In spite of the presence of many altcoins, Bitcoin still leads them all. Bitcoin is the leader among them in terms of both market capitalization and network size. Even the hashing power used for bitcoin mining is greater than any of the cryptocurrencies till date. Mining involves the contribution of processing power to sustain the bitcoin network. Miners supply the necessary processing power to solve the cryptographic equations to find new blocks and confirm the validity of transactions over the platform at the same time.

Mining in one form or the other is used by all cryptocurrencies. Most of these cryptocurrencies also share various similarities with bitcoin...

DEVTOME.COM HOSTING COSTS HAVE BEGUN TO EXCEED 115$ MONTHLY. THE ADMINISTRATION IS NO LONGER ABLE TO HANDLE THE COST WITHOUT ASSISTANCE DUE TO THE RISING COST. THIS HAS BEEN OCCURRING FOR ALMOST A YEAR, BUT WE HAVE BEEN HANDLING IT FROM OUR OWN POCKETS. HOWEVER, WITH LITERALLY NO DONATIONS FOR THE PAST 2+ YEARS IT HAS DEPLETED THE BUDGET IN SHORT ORDER WITH THE INCREASE IN ACTIVITY ON THE SITE IN THE PAST 6 MONTHS. OUR CPU USAGE HAS BECOME TOO HIGH TO REMAIN ON A REASONABLE COSTING PLAN THAT WE COULD MAINTAIN. IF YOU WOULD LIKE TO SUPPORT THE DEVTOME PROJECT AND KEEP THE SITE UP/ALIVE PLEASE DONATE (EVEN IF ITS A SATOSHI) TO OUR DEVCOIN 1M4PCuMXvpWX6LHPkBEf3LJ2z1boZv4EQa OR OUR BTC WALLET 16eqEcqfw4zHUh2znvMcmRzGVwCn7CJLxR TO ALLOW US TO AFFORD THE HOSTING.

The process of mining multiple cryptocurrencies is called merged mining. Merged mining can be used to maintain multiple cryptocurrency networks in a more economical fashion. With Bitcoin merged mining more mining power from those involved in bitcoin mining will be available for the altcoins. Though the Bitcoin network many not benefit much.

@Peter Tschipper - I am not surprised there was another one on Ubuntu. I've had it crash on two separate instances .....

I initially updated just one of my VPS's as I'd had issues with a self compiled Xpedited blocks branch previously (did not report that one as code was still in development). But these crashes happened with the supplied compiled binaries of the 0.12.1 release.

When the first one happened, I thought it was related to some scripts I was running / writing at around that time on the VPS, but I've not touched the one that crashed today since updating it that's why I posted here just in case it'd been reported before.

PS. From the observation, I think (on my VPS's) it takes around 2 days or so. We'll see if/when either crashes again and get the logs. In the meantime, thanks for attending to...

Tutorial on merged mining Litecoin / Dogecoin and other Scrypt Coins

Not to be confused with multipool mining, which switches to a more profitable coin automatically, merged mining lets you send hashes to multiple blockchains. That would mean that while mining Litecoin or Dogecoin, you would be able to mine other cryptocurrencies at the same time, as you no longer need to choose between mining one or the other coin. Mining would be more profitable by mining a primary coin and other secondary coins without affecting your maximum hashrate on the primary coin, and power consumption remains the same.

Merged Mining

Merged mining works like this, your generated hashes that could be the solution to the current block will be sent to two or more different blockchains to see if they are the solution. Since every blockchain which represents a coin would have a different solution, you are increasing your chances of solving a block by sending the hash to multiple...

MinerGate was the first pool to support merged mining of CryptoNote currencies. Now we are bringing you merged mining of Monero with DigitalNote and FantomCoin. In this article we are explaining why merged mining is one of the best ways to get profit from cryptocurrencies and give you some tips on how to start on MinerGate.

What is merged mining?

Merged mining is the process of mining two coins based on the same algorithm simultaneously. The best thing is that there is no decrease of hashrate for any of them, so you benefit from both without making any sacrifices.

Here is how it works. Every share sent by your miner is checked in the network of both currencies. It’s like being able to participate in two lotteries at the same time with one lottery ticket. Your chances to win in at least one of them are increased. The calculations are made on the main (parent) chain and the other coin’s chain (auxiliary) accepts them as valid.

Dave Carlson is running one of the largest Bitcoin mining operations there is.

He's set up an army of number-crunching computers in two warehouses at an undisclosed location in Washington State. The computers generate a ton of heat and burn through electricity, but Carlson says he's generating $8 million worth of Bitcoin per month!

He invited KOMO News, a local Seattle station, to come check it out. You can see he's got quite the setup:

Screenshot

Carlson's space is filled with computer boards, each housing several chips that do the actual Bitcoin "mining."

BitClub Network Mining Pool

We are attempting to build one of the largest Bitcoin mining pools in the world!

Our Public Mining Pool – www.BitClubPool.com

Bitcoin and other digital currencies operate as peer-to-peer networks, which means
everyone who uses the currency is actually a piece of the system. Mining is simply the term used for maintaining the block chain and verifying each transaction.

Miners use special hardware to solve complex math problems and are issued a certain number of new Bitcoins in exchange. This provides a unique way to issue the currency and also creates an incentive for more miners to participate.

As the popularity of Bitcoin increases more miners join the network, which makes it harder to solve these math problems. For this reason Mining is no longer feasible for an individual and it will continue to get even harder. This has led to the creation of Mining Pools, where many people combine their computing power and...

Dogecoin has officially switched to auxiliary proof-of-work (AuxPoW) mining.

The update now enables litecoin miners to process transactions, while providing an additional layer of security to the decentralized network.

The altcoin’s switch to auxiliary proof-of-work, also known as merge mining, has been in the works for some time. The move was announced this August after months of serious and, at times, passionate debate within the dogecoin community. The merge mining concept was suggested in April by litecoin creator Charlie Lee.

Dogecoin creator Jackson Palmer told that AuxPoW was necessary as the gradual decline in price had removed some of the incentive for miners to mine dogecoin. Further, any resulting network hashrate drop could have created the conditions for potentially malicious transactions to be fraudulently committed and confirmed.

Palmer said:

“One of the harsh realities of proof-of-work based...

Nothing guaranteed, of course this is only a rough estimate!
Do not enter commas, only dots for decimal separator. You can also calculate rented mining by setting “Power consumption” to 0 and “Cost of mining hardware” to the rent per time frame. Default values are for a system of four 6870s.

Estimate Strategy

Extrapolating bitcoin difficulty or price is pure voodoo. It is much easier to predict the relationship of the two parameters in form of the Mining Factor. The Mining Factor 100 is the value in USD of the bitcoins you can generate if you let a 100MHash/s miner run for 24 hours. If the Mining Factor 100 rises above $2 or so everybody buys mining equipment and thus increases difficulty. If it falls people will stop mining eventually. The estimate starts with the current Mining Factor and decreases it exponentially such that the decrease accounts for the factor decline per year. Please note that a profit/loss by holding the coins is not accounted for in this...
