[Pool Update] Epoch 227

Hey people!

We just transitioned into epoch 227 and the d parameter is now set to 0.5. This means that this is the very first epoch where the community pools produce the same amount of blocks as the governed BFT nodes. It really feels great to see the network going forward and forward every single epoch.

I did also already calculate the schedule for this epoch:

Checking leadership log for Epoch 227 [ d Param: 0.5 ]
2020-11-02 23:24:15 ==> Stolen by BFT for 88764, Cumulative stolen blocks due to d param: 1
2020-11-03 00:15:55 ==> Stolen by BFT for 91864, Cumulative stolen blocks due to d param: 2
2020-11-04 00:44:33 ==> Stolen by BFT for 179982, Cumulative stolen blocks due to d param: 3
2020-11-04 08:34:58 ==> Leader for 208207, Cumulative epoch blocks: 1
2020-11-04 20:46:39 ==> Stolen by BFT for 252108, Cumulative stolen blocks due to d param: 4
2020-11-05 14:37:25 ==> Stolen by BFT for 316354, Cumulative stolen blocks due to d param: 5
2020-11-06 10:42:21 ==> Stolen by BFT for 388650, Cumulative stolen blocks due to d param: 6

Note: The times shown refer to the central european summer time (CET, UTC+1).

As you can see there is an unlucky epoch lying ahead. We expect to produce one block this epoch and 6! blocks will be stolen by the BFT nodes. Thats very unfortunate as with the d parameter at 0.5 only about half of the blocks of a whole epoch should get stolen by BFT. In our case 6 out of 7 blocks are stolen this relates to 85% stolen blocks instead of 50%. There is still a little chance that one of the BFT nodes misses a block and if that happens, be sure that the pool is ready to take over this work 😉

If you’re interested in whats going in the cardano space, make sure to check out the October Cardano monthly update. Great news and information in there and definetely worth listening/watching.

Lets hope for a better epoch 228! Thanks for stopping by. Talk to you soon 🙂

[Pool Update] Epoch 225 & 226

Hey People!

Just a little update for everyone not following on twitter or telegram.

Last epoch (225) we produced 2 blocks of statistically intended 1.9 blocks and thus had a slight overperformance of 105% 🙂

The even better news; I have already looked at the schedule for 226 and I don’t want to withhold it from you:

Checking leadership log for Epoch 226 [ d Param: 0.52 ]
2020-10-28 01:13:12 ==> Stolen by BFT for 8901, Cumulative stolen blocks due to d param: 1
2020-10-29 06:31:34 ==> Stolen by BFT for 114403, Cumulative stolen blocks due to d param: 2
2020-10-29 09:58:50 ==> Leader for 126839, Cumulative epoch blocks: 1
2020-11-01 06:16:14 ==> Leader for 372683, Cumulative epoch blocks: 2
2020-11-01 07:02:19 ==> Stolen by BFT for 375448, Cumulative stolen blocks due to d param: 3
2020-11-01 13:46:51 ==> Leader for 399720, Cumulative epoch blocks: 3
2020-11-01 21:30:50 ==> Stolen by BFT for 427559, Cumulative stolen blocks due to d param: 4

Note: The times shown refer to the central european summer time (CET, UTC+1).

Overall we’re heading for three blocks in 226 (if there are no slot battles) which means an overperformance for this epoch and therefore good rewards. If d were zero we would even produce 7 blocks this epoch. Really looking forward for d to further decrease in the future.

Thats it for now. Talk to you soon 🙂

EDIT: Due to a miscalculation in the last schedule we produced only two blocks instead of the above mentioned three blocks. This still means a performance of 105% but I just wanted to clarify this. Transparency is key and therefore I do want to excuse for this mistake!

[Pool Update] Summary of the last few epoch

Hey People,

You haven’t heard from me on the website for a while now and therefore it’s time for a small update.

We were quite lucky at the beginning of the mainnet but lost luck a bit in the last few epochs. There was epoch 220 and 223 completely without a single block, which made some bigger delegators left. We still have a good base of delegators and I do want to thank every single one of you!

I wanted to let you know, that the nodes ran through all epochs flawlessly and we had no issues whatsoever.

What I do want to state in this little post is that we’re currently losing many many blocks to the BFT nodes. For those of you who don’t know what that is: They are basically the “official” nodes that ran the network until the Shelley era. Since then the community pools started taking over the network with a slow decrease of the d parameter, which relates to how many blocks the community pools can produce. Currently (epoch 224) the d parameter is 0.56 which means that 56% of the blocks are made by the BFT nodes and 44% are made by the community pools.

I went to the leader logs for epoch 223 and they state the following:

2020-10-13 03:54:45 ==> Stolen by BFT for 14994 
2020-10-15 03:54:56 ==> Stolen by BFT for 187805

Note: The times shown refer to the central european summer time (CEST, UTC+2).

This means that we would have produced two blocks when d would be 0. As it’s not we were unlucky and lost both of our blocks to the official nodes. There is really nothing any pool can do about losing blocks to the BFT nodes. We just need to wait for d to decrease further. It’s also possible for me now to take a look at the current epoch 224, where we have a quite similar picture:

Checking leadership log for Epoch 224 [ d Param: 0.56 ]
2020-10-19 08:29:29 ==> Stolen by BFT for 117878, Cumulative stolen blocks due to d param: 1
2020-10-21 22:24:58 ==> Stolen by BFT for 340807, Cumulative stolen blocks due to d param: 2
2020-10-22 10:22:03 ==> Stolen by BFT for 383832, Cumulative stolen blocks due to d param: 3
2020-10-22 13:04:58 ==> Stolen by BFT for 393607, Cumulative stolen blocks due to d param: 4
2020-10-22 13:48:01 ==> Leader for 396190, Cumulative epoch blocks: 1
2020-10-22 23:37:45 ==> Stolen by BFT for 431574, Cumulative stolen blocks due to d param: 5

Note: The times shown refer to the central european summer time (CEST, UTC+2).

What we can read here is that we would produce 6 blocks if d were 0, but as it’s not we lost 5 blocks of those 6 to the BFT nodes. If we consider the current d parameter we statistically should have made about 2-3 out of those 6 but as there is still some randomness/luck involved, we will only produce 1 block in epoch 224 (if there isn’t a slot battle for this particular slot).

I am looking forward to a better future as d will decrease further. I need to say that I’m still dedicated to Cardano and to running this stakepool.

Some good news at the end. During the last epoch I upgraded the pledge to 25k ADA and also assigned a new domain to the pool. From now on everyone will be automatically redirected to the new domain fairpool.eu, which is also the official domain registered on the blockchain with this pool. It is much better to read and to remember, plus looks better and more trustworthy.

Stay tuned for more updates and consider following me on Twitter or join the telegram group if you want to receive more frequent updates or just want to have a nice chat with me.

Talk to you soon! 🙂

Current ROS: Big pools vs. small pools [UPDATE]

Hey people,

In this article I do want to talk a little bit about the current return of stake (ROS) and how the ROS of small pools compares to the ROS of bigger pools. I guess some of you will be surprised and I really hope some of you will think about their current delegation and consider delegating to smaller pools.

As we do have some first data now, we can actually start to do some calculations. Yes, there will be some changes over time and as I’m no fortune teller, I will only look at the data we have at hand:

I am using the data from https://pooltool.io/ as they already provide information about the ROS of pools. So lets clarify what the ROS is: it basically tells you how much return you will get of your invested stake in one year. E.g. if you have 100k ADA and you delegate your stake to a pool which has a ROS of 5% you’ll have 105k ADA at the end of the first year.

So let us compare the average ROS of the top 20 pools (without saturated ones) to the ROS of the pools on the rank 200 – 220:

Calculation for top 20 (without saturated pools):

5.77 + 5.86 + 5.81 + 5.80 + 5.77 + 5.59 + 5.77 + 5.78 + 5.77 + 5.77 + 5.37 + 5.48 + 5.6 + 5.83 + 5.49 + 5.48 + 5.59 + 5.74 + 5.37 + 5.48 = 113.12 / 20 = 5.656%

Calculation for rank 200 – 220 (with at least one block):

5.89 + 5.82 + 5.82 + 6.55 + 0 + 6.16 + 6.32 + 5.77 + 7.15 + 6.02 + 4.08 + 5.78 + 5.96 + 5.91 + 5.83 + 6.64 + 5.78 + 7.04 + 6.53 + 6.91= 115.96 / 20 = 5.798%

Notes: Pools sorted by lifetime blocks; for comparison: Avg. stake of the top20-set: 144M; Avg. stake of the smaller-set: 6M

As you can see the ROS of the much much larger pools is not even higher than the ROS of the smaller pools. In fact, in this example, its the other way around the smaller pools gave you a 0.142% higher ROS. So what does this mean for you as a delegator: It is not really important if you stake with a very large pool or with a medium-sized or a small pool when you only consider the ROS. But I think many of us know that the ~5% per year are only a nice bonus and the tip of the iceberg. If Cardano succeeds in its vision it has a much higher potential than those gains. For Cardano to succeed we need a healthy, diverse ecosystem with as many reliable pools as possible and we will only reach this with true decentralization on which you as delegators can have a direct influence.

So please reconsider delegating to smaller pools, think about what it means for Cardano when the stake is to concentrated to big pools and what it means when there are stake pool operators that are obviously running more than a few pools at once to attract more and more stake and delegators.

I hope this was a helpful little comparison for some of you. Remember that this was just an example, there will always be a certain luck factor but in the end we will be on about the same level with ROS.

For everyone who already delegates to this pool or thinks about delegating: This pool has currently a ROS of 5.79%

Thanks to every single delegator, without you the operation of this pool would not be possible.

Talk to you soon! 🙂

[UPDATE 31st August 2020]:

As some people mentioned, the given ROS values by pooltool are not 100% correct as they seem a bit of of the real values when calculated for a single delegator. The overall numbers seem to high throughout all pools. This means that the ROS values are not correct in their absolute numbers but the ratio of the numbers should be correct. I’ll do a similiar post like this in some time when we have better data 🙂

Epoch 213 & 214

Hey people,

Short update from my side:
Relays and Producer ran flawlessly and without downtime in epoch 213. We were rewarded with an overperformance in this epoch and produced 3 blocks instead of the statistically planned 1.9 blocks. The rewards for epoch 213 will be paid out at the beginning of epoch 215 on 02.09. I am happy that you will be given well-deserved rewards. Thanks for delegating to this pool.

In the course of epoch 214 it is planned that I will add some pledge to the pool and in the course of the re-registration also add twitter to the extended metadata to make this directly visible on the relevant websites like adapools.

Remember: In epoch 214 the d-parameter will be reduced by another 0.02 to 0.76, which means that community pools will produce 2% more blocks and our chances for blocks will increase again. If you want to read some more about the d-parameter and the way of Cardano towards full decentralization I highly recommend this article from the IOHK blog:
The decline and fall of centralization

I’ll be monitoring the servers during the next epoch transition but do not expect any problems whatsoever. To give you some insights, this is a small part of the monitoring dashboard I am looking at:

Part of the monitoring system of Fair Pool #01

Hope you all enjoy these days with Cardano. Talk to you soon 🙂

Some information about rewards

Hey people!

I received several message from delegators reaching out to me, asking when and how often they will receive rewards and I wanted to clarify this for everyone here:

We’re currently in epoch 213 (23-28 August). At the beginning of 213 the first rewards were distributed. Those came from epoch 211 (13-18 August) which was the first epoch were blocks could have been produced.

Statistically we should have made about 1.5 Blocks in 211. But there is a certain randomness within the algorithm. So we were unlucky and weren’t assigned to a block. This has nothing to do with poor performance of the pool as we were up and running all the time. Therefore there are unfortunately no rewards yet.

But the good message is: We produced 2 blocks in epoch 212 so you will receive rewards for that at the beginning of the upcoming epoch 214 (28 August)! 🙂

Rewards are distributed completely automatically and you will find them in your wallet. Assuming we are able to produce a block every epoch, you will also receive rewards every epoch, so every 5 days.

Please take a short look at the “Reward Schedule until EOY” for further explanation if you’re interested.

Please note that the blocks assigned to pools are determined by an algorithm which is statistically based. So you will see that the whole system levels out over a longer period of time. That means, that we may not produce our expected blocks in one epoch but then exceed the expected blocks in another epoch. Over a longer time frame it will be the same as consistently making the same amount of blocks.

Thanks for staying with me. Smaller pools really need every delegator! Trying my best to attract some more people to the pool.

Talk to you soon! 🙂

We produced our first block!

I am very very happy to announce, that we produced our first block this night! Getting this message was really a relief, because now it is confirmed that the pool is correctly set up and running smoothly. I would also like to thank everyone who has delegated their stake to this pool and therefore their trust. Without you it would not be possible to run this pool in the long-term. Love you all for that!

Since we are currently still at d >= 0.8 this block also means that we already get the full rewards for this epoch. So it doesn’t matter if we get another block or not, the rewards remain the same. But this will be changed from the next epoch on.

Stay tuned and look forward to more content in the near future. I will not only post regular updates on the website, but also set up a telegram channel and open a Twitter account. So you can choose your preferred communication channel and stay up to date.

Talk to you soon 🙂

Epoch 211 & 212

Hey people,

I’ve just been watching the transition from epoch 211 to epoch 212 and I can tell you that I’m always excited when I think about how Cardano is currently doing, how well the community is holding together and how we are on track to permanently change our future. I would like to seize the opportunity to recapitulate the last epoch 211 and to give a short outlook on epoch 212.

The less pleasant news first. Unfortunately, the pool did not produce a block in epoch 211 despite a promising stake. In this regard I have to state the following: The pool was online the entire epoch with no downtime and no technical problems whatsoever. In epoch 211, 2160 blocks of community pools could theoretically be produced with parameter d = 0.9. With a total stake of about 10B ADA the following calculation results: 10B / 2160 = 4.62M, which means that a pool needs an average of 4.62M stake to produce one block. Unfortunately, a little luck is also necessary. But we did not have this luck this epoch. This also means that we will not receive any rewards for this epoch. I was hoping to reward you for your stake until the last block and I am honestly a bit disappointed that it didn’t work out.

But let’s talk about the better news: The pool has handled the epoch transition flawlessly. Some other pool operators had some problems here, but these will be solved with future updates of the software and we will get an even more stable network. Another positive aspect is that even very small pools were lucky in the slot lottery of epoch 211. The smallest pool had a stake of only 20.2k and still had the enormous luck to produce a block. And you know what, I think that’s great! Because it shows that all SPOs have the chance to participate in the network and that even the smallest pool helps to stabilize and decentralize the network. In total, over 250 different pools have produced blocks, which is a lot considering that only about 10% of the blocks in Epoch 211 were produced by the community.

Let’s take a look at epoch 212: At the beginning of this epoch d was reduced to 0.8, which means that the community will produce twice as many blocks as before, around 4320. The total stake at the beginning of the epoch was around 12.76B according to the same calculation as before a pool needs about 2.95M stake to produce one block. The active stake of this pool is 7.37M. We should therefore have again a quite good chance to produce one or more blocks. One more thing about the rewards, as long as d >= 0.8, all pools will receive full rewards depending on the percentage of their stake of the total staked ADA. So it makes no difference if the pool produces 1 or 10 blocks, the rewards remain the same. This will change once d is < 0.8.

Last but not least I would like to thank all of you for delegating your stake to this pool and thus placing your trust in us. With your decision to delegate to a rather small pool you actively support the development and decentralization of the network. No matter what happens in this epoch, I assure you that this pool will remain, I will continue to actively participate in the community and will be available with all means and knowledge to further advance Cardano.

Hope you’re staying with us! Talk to you soon 🙂

Staking with Yoroi

Today there are some great news for you people: The Yoroi extension is finally ready for Shelley including Ledger and Trezor support!

Initial Setup

Let us take a closer look at the delegation process:

  • Please make sure, that you’re using the current version of Yoroi and downloaded it directly through the chrome web store you will find the link here: https://yoroi-wallet.com/#/
  • Please also make sure that you’re using an up-to-date hardware wallet if you are using one
  • Click on “Add” and confirm the operation with “Add extension”
  • Select your language and press “Continue”
  • Read and accept the terms of use
  • Now you can choose the level of complexity: for this guide I am staying with the simple view
  • You can now decide whether to enable Cardano payment URLs or not. It’s up to you.
  • You have now worked your way through the initial setup. This process is only needed when you first install the Yoroi extension. In the next Section you’ll find the instructions on how you can add a wallet to Yoroi.

Adding a wallet

  • We’re finally able now to connect our hardware wallet, restore a wallet or to create a new one. Just choose what you want, Yoroi will guide you through the corresponding steps. As they are explained very good within Yoroi I will not cover them all.
  • If you do already have a Byron wallet, you just create a new Shelley wallet and send your funds from your Byron to your Shelley wallet. This is necessary as staking is only possible from a Shelley wallet. I’ll explain it in more detailed later.
  • I’ll show you the process of connecting your Ledger Hardware Wallet. So we choose “Connect to hardware wallet”, then select “Cardano” and afterwards choose “Ledger Hardware Wallet”
  • Then you need to select which type of wallet you do want to restore.
  • If you never used your Ledger after the Shelley hardfork you first need to choose the Byron-era wallet here. In a later stage you should then be prompted to automatically transfer your funds to your Shelley wallet. If not contact the section: Transition from Byron to Shelley
  • Read the instructions here carefully and make sure that all prerequisites are in place, then press “Next”
  • Connect your ledger to your computer, unlock it, open the cardano app and click “Connect”.
  • A new tab will open where you need to choose your specific device.
  • You now need to export your public key when prompted on your ledger device. Please note, that this request may happen twice, just export your public key both times. Afterwards you should be able to name your wallet.
  • If you restored a Byron-era wallet you’ll need to send the funds from it to a Shelley-era wallet. As mentioned earlier you can just go through this process again to add a Shelley-era wallet.

Tansition from Byron to Shelley

As stated before: Staking is only available when you are on a Shelley wallet. The process of going from Byron to Shelley is basically only a single transaction where you send all your funds from your Byron to your Shelley wallet.

This is the manual way of going from a Byron to a Shelley wallet. I already talked to the developers of Yoroi and they said, that you should be automatically prompted on Ledger devices to transfer the funds automatically. For any other wallet type you can do it either via the the “Claim / Transfer” page or follow this guide and transfer the funds over manually. No matter which method you choose, the result is always the same.

Prerequisites: You need the Yoroi Extension with your old Byron wallet and a new Shelley wallet already added. It is described in the sections before how you can add new wallets to Yoroi.

  1. Open your Shelley wallet and copy the receiving address which can be found in the “Receive” tab

2. Switch to your Byron wallet and send all your funds to the copied receiving address of your Shelley wallet

After confirming the transactions you should see your funds in your Shelley wallet within a few minutes. Congratulations you switched from Byron-era wallet to Shelley-era wallet. You can now go on to the next section: Staking


If you restored a Shelely-era wallet you will find yourself in a view like this. Switch to the delegation tab here, where you’ll be able to stake your ADA.

  • You can now enter the Stake Pool ID to which you want to delegate. If I helped you with this guide, you are very welcome to use my pool: 6b51a5aae5b4b5f07f38acf12816b4f8a558ee2840d0dba69040aeb2
    You also have the advantage of very low fees of 0.5% and therefore get higher rewards than in other pools. You will also see some information about the pool and can complete the process by clicking the “Next” button.
    If you rather want to stake to another pool, just work your way through any of those explorers:
  • This is the final confirmation of your transaction. Insert your spending password and click “Delegate”. Your paying a fee of about 2.17 ADA, this splits up in 2 ADA for the first time your registering your stake address on the blockchain. This is a one time fee, which will prevent attackers from flooding the network with a huge amount of fake stake addresses and fake delegations. The remaining ~0.17 ADA are the current transaction fees.
  • Note: Hardware wallet users will do this confirmation directly on their device!
  • Congratulations, you’ve done it and successfully delegated to a stake pool.
  • If you switch over to the “Dashboard” tab you’ll be able to see your “Total Delegated” ADA, as well as the Stake Pool to which you are currently delegating. You do also have the information about upcoming rewards and will also see the rewards you earned once they are distributed in epoch 213 and the following ones.

Ledger Troubleshooting

Some people experiencing problems when trying to connect their Ledger to Yoroi. Here is some troubleshooting advice:

  • First make sure that its really not working with your current setup. Sometimes it helps when you try it a few times.
  • Check if your Ledger runs the latest firmware, if not update:
  • Check if the Cardano application on your Ledger is up-to-date (sometimes Ledger Live does not show an Update for certain Apps even if there is one; my advice: just uninstall and then reinstall the Cardano app)
  • Use a current version of Chrome with the Yoroi extension as this is the only supported setup
  • If you have installed more than more version of Yoroi (e.g. the testnet version) make sure to deactivate the one you’re currently not using, as they can intefere with each other
  • Check the Permissions of the Yoroi extension: Right click on the Yoroi icon -> Manage extension -> Check the “Site access” permissions, they should be granted for “*://connect.trezor.io/*” and “https://emurgo.github.io/*”
  • If it still does not work, try reinstalling Chrome as well as the Yoroi extension
  • There is also a FAQ video directly from EMURGO (the developers of Yoroi), which may help you with some questions:

Thanks for following me through this guide. If you have any questions don’t hesitate to contact me. I wish you happy staking! Talk to you soon 🙂

We’re going to produce blocks. [Update #2]

First of all a big thank you to all people who delegated their stakes to this pool. I have good news for all of you: We’re going to produce blocks in epoch 210 and we will therefore be among the first pools ever to create blocks in the shelley mainnet.

At exactly 21:44:51 UTC on August 3, 2020 epoch 209 started and the very first stake snapshot took place.

At this point in time 4,273,250.559953 ADA were delegated to this pool. Based on the calculations the stake is high enough that we will produce blocks in epoch 210 and receive rewards for that. The currently expected yearly rewards should be around 4.7%. Depending on the development of the pool, up to 5.2% are possible.

We had a good start and we’ll continue to do everything in the future to offer you safe and reliable staking.

For more information and general FAQs regarding the Shelley hard fork, as well as delegation & rewards you could read this blog post: The Shelley hard fork: all you need to know


As discussed by Charles in his video about “The Shelley Hybrid Era and the d parameter” the above mentioned delegation cycle was postponed by one cycle for the whole cardano network. According to this new cycle pools will start making blocks in shelley epoch 3 (211) instead of shelley epoch 2 (210). This affects every pool in the network. Just wanted to keep you informed.

[UPDATE #2]:

To keep you up to date here are some current numbers:

At 2020/08/08 21:44:51 UTC epoch 210 started and the second stake snapshot was taken. As I already mentioned in the first update the delegation cycle was postponed, which means that this snapshot will (hopefully) be the basis to determine who will be making blocks in epoch 211. The good news: We’re still in! As of my estimations at the time of the snapshot about 6.72 million ADA were staked in this pool, which should be (according to my calculations) enough to mint at least one block (which requires about ~4.6 million ADA staked) and therefore earning rewards. Since the selection of slot leaders is still subject to a certain randomness we need to wait for epoch 211 to see the real numbers. I also rechecked the expected yearly rewards and they are still floating around 4.7%. Please note, that the rewards could be lower or higher in the first few epochs but will level out over time.

Talk to you soon 🙂
