Monero XMR Mining Pool Frequently Asked Questions FAQ - XMRPOOL.EU

Here is the list of the most frequently asked questions. Please take some time to read them before asking for support! Most of the questions we are asked are found right here.

Maturity block theft, what is it?

There is a known exploit of PPLNS whereby a miner can use nice hash to hit the maturity of a just found block with many MHs to cause the allocation of shares to be unfairly distributed. It is not uncommon for a maturity block thief to hit a pool with 10MHs or more. We will confiscate your reward if you decide to try and steal the maturity blocks. Our pool is run by dedicated miners and we will not tolerate theft of our hard work. Just do not do it and play fair, you will not get you reward back.

How can we offer zero pool fees?

We believe very strongly in the fundamental rights of the individual, we believe in freedom of speech, freedom of expression, and the right to privacy. Thats just to name few of your, mostly forgotten, human rights. We believe that the Monero project answers one of these rights, which is your right to financial privacy. How do companies like Amazon, who paid only £4.6 million in the UK for their corporate tax bill justify it? Remembering that your grandparents will pay a higher percentage of tax on their pensions. Government snooping and the collection of data by almost all big corporations is also a big issue. There is something very wrong in the world, so what can we do? We decided that we could contribute our servers,time and fiat currency to supporting the Monero project. We take the hit by running a free pool, so you dont have to. Do not mine XMR just for profit, mine it because you believe in the project and the Monero community. Happy Mining!

What is the "MiningBonus" worker I see on my worker list?

The "MiningBonus" hashes are sent directly from our own in-house miners and show up in your account as a rig called "MiningBonus". We are adding about 50% of our entire hash-power to our long term loyal miners accounts. As we add more mining rigs to our own farm, there will be more hashes to spread around. Our top 10 miners, listed by hash-rate, will also receive around 10% extra hashes. These are added to their hash-rate also as a rig called "MiningBonus" once they have mined in the top 10 for round 24 hours. If you have been mining for a long time on our pool, and you don not receive the mining bonus, join our slak channel and let us know, we will be happy to review your account and add you to the bonus system.

What is the lottery and how does it work?

The lottery system was kindly written for us by one of our miners. Upon the discovery of every new block, the system picks a new lucky miner from the list of our loyal miners. This miner is given an extra rig in their account called "Lottery". This lottery is intended to be a bit of fun and to make the long days of mining more interesting. The lottery rig will be upgraded to around 10Khs very soon but for now is only a 2Khs test system. The lottery hashes are mined directly for you from our own server farm, as this farm expands we will add more hashes to this rig.

What is the CryptoNight V8 PoW and why do my workers keep getting banned?

Please check that you are mining using the CryptoNight V8 PoW as non compliance now incurs a 1 hour ban for the offending IP. We have had to introduce this as many miners are still submitting invalid bad shares. The V8 PoW came into force on October 18th 2018, please do not submit V7 shares to the pool you will be banned.

A list of some Monero XMR CryptoNight V8 compliant miners can be found here.

A common reoccurring subject for crypto currencies has been ASIC resistance and how we should react to any (potential) threat from ASICs. The article on the link below, sets out our (somewhat) formal stance on ASIC resistance and our intention to maintain ASIC resistance by swiftly reacting to any potential threat from ASICs and considering slightly modifying the PoW at every hardfork." More information here from the official Monero web site Monero PoW Change.

I've been mining for X hours and my pending balance has not changed yet. Why?

Your pending balance will increase only when the pool finds a block and the block is mature. A block is only Mature when another 30 blocks have been found in the whole Monero network. To make it easier to understand block on the "Pool blocks" page will turn green when the block is Mature. After that the pool will automatically calculate the shares and increase the pending balance of all miners taking part in mining. The automatic payment module runs every hour but be patient as sometimes there are hundreds of miners to pay in every cycle.

My IP is banned or I am getting the message "your IP is banned"

XMRPool validates every share that miners send. From time to time miners are sending invalid bad shares. If the pool detects that one of them is sending invalid bad shares, over a short period of time, it will automatically ban that worker for 10 minutes.

What is the reason of the invalid shares? Usually over-clocked or broken hardware.

I have a big list of unused workers. How can I remove the old workers?

Workers which are older than 7 days (last share submitted is older than 7 days) are removed automatically by scheduled script.

What is an address with a payment ID or what is an integrated address?

Address with payment ID. These types of addresses are usually used by exchanges where they have a single Monero wallet (address) but multiple payment IDs for the customers. Think of the Payment ID as a message attached to the transaction so that you can be spotted in their wallet. Most exchanges or systems that use a Payment ID like ShapeShift will generate a Payment ID for you.

Integrated address. These are almost the same as address with payment ID but id is merged into the main address - that's why this address is longer (106 chars) than standard wallet address (95 chars).

Minimum payment threshold for both address with payment ID and integrated address is 2XMR.

Do I need a payment ID to receive payout?

In most cases you do not need payment ID. If you are using standard Monero wallet (95 chars) NO - you do not need a payment ID to receive a payout.

If you are mining to exchange which is using a payment ID then YES - you need a payment ID to receive a payout.

What is an orphaned block? Why is the block red on the "Pool blocks" page?

A great explanation of what an orphaned block is, can be found here: What are orphaned blocks?

There is no reward for orphaned block.

I did not receive a payment but the transaction is on my payment page. What is going on?

In almost every case the issue with this type of problem is with the use of the old daemon / block-chain which is part of an old wallet. Most problems such as this have arisen since the V8network upgrade along with the new Monero 0.12.0.0 Lithium Luna Wallet Upgrade. Download the entire new wallet and re-install it. The installation will be fast but the syncing process may take a day or so as you may need to download the new block chain, which is around 65GB. A list of all the official Monero downloads are located here https://getmonero.org/downloads/.

I want to join the pool. How can I start mining on xmrpool.eu?

This pool is anonymous and free for anyone. If you wish to mine with us simply start from "Getting started" page.
