[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! 🙂

[Pool Update] Current developments (ROS, Pledge, Delegators)

Hey people,

Want to give you a short update here:
I recently updated the pledge of the pool from 10k to 15k. In the upcoming months, I will regularly update the pledge to be prepared when the parameter a0 gets increased. This parameter reduces the rewards of the pool when its pledge is too low. It should incentivize SPOs to pledge more ADA to their pool, thus making it more reliable and the network more stable. Currently, the a0 parameter is quite low and therefore not much pledge is needed to avoid reduced rewards. As you will see in a moment, this pool offers a very good ROS despite having (in comparison) not a very high pledge, which is currently no problem.

As the first few epochs are over now and we have some data about the current ROS of the pool I wrote together the data of different explorers:

ExplorerROS Epoch 212ROS Epoch 213
adapools.org5.37%8.53%
cardanoscan.io5.26%8.279%
pooltool.io5.26%8.279%

As you can see Cardanoscan and Pooltool are showing the same ROS and as to my calculation this ROS is the correct one. I am very happy that we have performed so well so far and are generating very good rewards. Another piece of good news, the rewards for Era 214 will also be very good because statistically, the pool has produced more blocks than expected. It is estimated that Era 214 will produce about 7.9% ROS.

If we now take a brief look at the current epoch 215, we see that we have already produced 3 blocks. This means that we again have an overperformance and the rewards for 215 will be above average. Since the epoch is not over yet, it can only get better.

A nice development is also the number of delegators in this pool. We see a constant increase and currently there are 93 people delegating to this pool. If we compare this value with other pools with a similar stake, we see that we have an above-average number of people. I see this as a very good thing because we are not as dependent on large individual sums as other pools. On the other hand, I would love to welcome a whale here, as it will give us another nice boost in stake, which will definitely support the block production. So far you can see that the ROS is worth delegating to smaller pools and it has hardly any advantages in this regard to support the big players.

I would like to thank everyone here for delegating to this pool. If you have any questions, suggestions or ideas for improvement please do not hesitate to contact me. I have also created a telegram group where you can meet not only me but also other people who delegate to this pool. I would be very happy to welcome you there.

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 🙂

Another milestone was reached

At the 13th August 2020 21:44:51 we transitioned into epoch 211. Right at this moment the d (“decentralization”) parameter was lowered from 1 to 0.9. This parameter determines the number of blocks produced by OBFT nodes and thus simultaneously specifies how many blocks are produced by community pools. This is quite a big step as IOHK is slowly but surely handing over control of the network to the community.

But what does d = 0.9 really mean? It means that from epoch 211 on, about 10% of all blocks are produced by community or SPOs (Stake Pool Operators) operated nodes and receive rewards for their produced blocks. The d parameter will be decreased every epoch (so every 5 days) by at least 0.025, so that we will see more and more decentralization as well as more blocks produced by the community.

Here are a few key dates:

  • 13th August 2020: Start of the first Epoch (211) where community pools produce blocks
  • 18th August 2020: Transition to Epoch 212, where the rewards for epoch 211 will be calculated
  • 23rd August 2020: Transition to Epoch 213, where the rewards for epoch 211 will be distributed

Please note: That this process is overlapping for the epochs so in 212 there will also be blocks produced which then gets calculated in 213 and distributed in 214. So this goes on and on.

I was live on the screen during the first produced blocks and it was awesome to see the transition. Congratulations to the SPOs which were among the first people producing blocks in this new Cardano Era!

Hope we will see our first block soon. I’ll keep you updated! Talk to you soon 🙂
