In a more mathematical analysis, if we "start" the pool at a queue of length 0, it will grow fast initially, as the the odds it finds a block faster that the submitted shares is high. But when it will be a few blocks deep, that queue provides a "cushion" that makes unlikely the queue will empty again. The longest the queue, the unlikelyest it will empty. But the odd is never 0, only decreasingly small... So it will ALWAYS empty again sometimes, but in longer and longer intervals, and each times it empties, it will grow a bit. One can then calculate that the expected growth of the cue is that it's length will be proportionnal to the square root of the time elapsed since the last time it was emptied. The exact proportionnality factor will depend on network difficuly, hashrate of the pool, etc... (For the mathematically inclined, sqrt(ht) (where h is the hashrate and t the time) is the standart deviation of a poisson distribution, the distribution that describes the bitcoin behavior. Correct me if i've made a mistake.)

There are a lot of misconceptions in your analysis, the odds of hashing a block with positive luck is exactly 50%, thats the reason we can define good or bad luck, and how the difficulty works.
On the other hand finding a block with good luck does not shrink the queue as you may take into account the shelved shares that everyone has, so you can assume safely that unless we hit a extremely lucky streak and all shelved shares all cleared, we will never award less than 25BTC, so the queue will only shrink due to payment limit shenanigans or manual payouts.

Also can you share the code or pseucode of your graphs, I am not sure how are you doing the calculations (not saying they are wrong, just I don't see where does they come from).

Also it is fun to note that in with the last 2 blocks the queue increased another 6BTC with "bad luck"

Hi, I am sorry if this has been already asked but a naive search couldn't find anything.

Can someone tell me how the fees are distributed and what is the "Eligius Payout Change Aggregation" address?

I am trying to understand how the fees work and how it is possible that the payout qeue has grown from 1 block to 8 in less than 3 days.


As different addresses reach the payout threshold, they enter the payout queue.  A small amount of mining that is spread among many addresses can bring all of them across the threshold, and thus make the payout queue large, both in the number of addresses, and the amount of payout.


Even taking that into account that it should stabilize soon after the manual payout process. At every block 25BTC + fees? are awarded for every block and 25BTC+fees are paid, some people with previous pending balances can reach the threshold but after the manual payout a lot of users pending balance will be 0 (indeed the majority, right now with 8 blocks there are over a thousand address in the qeue and just 5500 hashing accounts, this weekend with 60 blocks in the qeue, almost everyone should have been in the qeue).



The question is, what does "stable" look like.  Large numbers of addresses enter the queue from relatively small recent earnings.  Many of these have had a long time elapse since their last payout, and they get put at the top of the queue.

One of my accounts has almost 2 BTC in the unpaid shares (I forget their name for these).  A few lucky blocks will pay those unpaid shares to me.  There are several things going on.  It would be interesting to write a program to model "steady state" using realistic account data.  That data is pretty available from Eligius.


Shelved shares are just the same as normal shares for CPPSRB, it will reward recently unrewarded shares (from this block of olders depending on the luck of this block), and as I understand it will always awards 25BTC (still unsure about fees), so every block 25BTC will be awarded and 25TC will be paid, shelved shares does not change that.

So in a perfect world when everyone starts at 0 earnings and there is not minimum for payout, the payout queue will always be 0, if it starts with good luck then some BTCs will go to the tip jar, otherwise shelved shares will appear, but the queue will be always 0, due to "Eligius Payout Change Aggregation" maybe over the time it will increase but really slowly (the change address always receive a little more than 0,001BTC).

With minimum payout then the first blocks will not pay the full 25BTC as while 25BTC was awarded only the fastest miners will reach their minimum to be paid that same block, indeed this is what happened during the first blocks after the manual payout.

Several blocks started to put a big share of the block in the change address from block #300169:
http://eligius.st/~wizkid057/newstats/blockinfo.php/000000000000000003fb8ec85a29533067c9b4d56dec9ed595b8f29fcaac9ca0

...
until block #300198 (http://eligius.st/~wizkid057/newstats/blockinfo.php/00000000000000002a2f650a9cbc4ba83ea92a97914c4b89ce300e7630ef7beb) where we entered in failsafe for just one block and queue started to grow (at this point there were 70BTCs not paid since the manual payout).
After that point there are some blocks with some noticeable change 6.6BTC in total.

And I have found the problem there were another 3 blocks in failsafe on 12/05, those add another 75BTC to the queue for a total of more than 150BTC, the queue is not at 187BTC so maybe there was another block in failsafe in later days or just unpaid balances reaching the minimum.


Looking at the blocks there are 3 problematic blocks that doesn't seem regular nor failsafe but those were before the manual payout:
http://eligius.st/~wizkid057/newstats/blockinfo.php/000000000000000020361d05189b54ff412115486568c83c648b04e796fe58de

Still usure on how the fees are used and how does the change address, offiline address work, I thought that offline was just for donations, but it seems that it is used to store BTCs when there are no address to pay in the queue.

El problema es que lo vendemos muy mal diciendo siempre que las 6 confirmaciones es la verdadera seguridad, abría que decir siempre que cualquier transaccion recibida en la red es inlcuida a excepción de casos muy puntuales o mala fé del comprador, que basicamente es lo mismo que ocurre con las tarjetas de credito, cualquier transaccion es oficial quitando muy raras excepciones o mala fé del usuario.

6 confirmaciones es una seguridad "rock solid" que tienes en una hora, comparativamente cualquier otro medio no tienes esa seguridad ni en meses.

Quizá el mayor problema es de las fees pero aun así suele ser marginal, lo que siempre he pensado y no he visto que esté hecho en ningun wallet es la posiblidad de redifundir una transaccion recibida, si por lo que sea a tu nodo llega el pago pero ves que no se acaba de incluir en la blockchain guardar esa transaccion y poder reenviarla siempre que siga siendo valida (no haya double spend), la transaccion se recibe ya firmadita así que debería ser obvio guardarla y después de cada bloque que no la incluya redifundirla por si ha tenido problemas de conectividad (es algo que he visto pasar varias veces con el wallet de blockchain.info).

Sin acritud, pero tanto los Antminer S2 como los SP10 tienen mejor ratio W/Ghs, el S2 por poco 1.1W/Ghs, el SP10 por algo más 0.89W/GHs (como referencia el Terraminer IV son 1.16W/GHs)

El problema precisamente es ese, que en un sistema trustless como es este es muy complicado certificar cosas como esa, como mucho se me ocurren dos opciones directamente que pasado X tiempo sin movimiento no se puedan usar o que cada año sin uso se pierda un porcentaje.

Quiza tu sistema se pudiera aplicar en un sistema PoS, donde debas certificar que son tuyos las monedas antes de recibir más, sería un alicienta a que las monedas se usaran, pero en la base de datos comun la accesibilidad no es algo que se pueda comprobar y el PoW no ayuda tampoco en esto.

De todas formas no creo que el valor realmente esté ligado a la cantidad de monedas que existen, más bien a las que circulan de forma constante que es una minima parte, si que es verdad que estabilizas ya que aseguras que no pueden aparecer millones de monedas en circulación de la nada (justo lo que controlamos con la generación estable de monedas por otro lado), pero no sé si merece el esfuerzo.


Asurmen: No digo que esté justificado el cambio para nada, digo que la fungibilidad ya está limitada en algunos casos y no sucede nada, que era una critica que se había hecho.

Hombre los distingue tanto como los de las propuestas.

Podemos decir que los 100 primeros bloques no se pueden usar y después de 1.000.000 de bloques sin usar un output se destruyen.

Todos los output tienen que cumplir las mismas normas y por tanto son iguales, si la queja es que hay outputs que no se pueden usar en algunas condiciones eso ya pasa ahora mismo y seguiría pasando con la propuesta.

Pues creo que aqui desbarran un poco los abogados, MTGox Poland es una empresa independiente de MTGox Japon que es la que ha entrado en concurso, ni KK Tibane ni Kylehosting (o como sea) que también son del grupo están en concurso, así que dudo mucho que esté congelada, Mtgox polonia tendrá todo el dinero en € de mtgox que son unos cuantos millones así que no es tonteria ir a por ella igual que en USA se ha ido a por MTGox USA y por lo que se sabe no han conseguido ni meter a esa empresa bajo el paraguas de protección del proceso de Japon (entre otras cosas por que MK no hay querido salir de japon).

Eso iría encontra del principio de fungibilidad, es decir, los bitcoin no serían todos iguales y eso es peligroso para bitcoin

Por desgracia esto ya es así, los bitcoins recien generados tienen que madurar antes de poder ser gastados, sinceramente no entiendo muy bien la razón detras de esta condición pero existe y de hecho recuerdo que a MTGOX le causó parte de los problemas que llevaron a los problemas tecnicos de retiradas (que aparte de los de gestion tambien hubo problemas con retiradas que no llegaban).

So what are the odds of the first tape out having a design flaw that will make us have to wait through a second fab?

All ready discussed at length. We'll ship on time and on spec.

I have an SP30 order from you, and I want to believe.. But if you are so sure, why is this in your Terms of Conditions:

Quote
Delivery dates communicated or acknowledged by Spondoolies in the Order Confirmation are approximate only, and are dependent upon supply chain interruptions and stoppages, development delays, and other factors. Therefore, Purchaser shall not rely upon, and Spondoolies shall not be liable under whatsoever circumstances for any other estimation statement of expectation when delivery will occur.

How did the terms helped customers of: BFL, AMT, TerraHash, HashFail, CoinTerra, scammy VMC/AMC, etc customers? It didn't! Why are you stressing over this? Spondoolies Tech is the only company that funded itself for over 9 months and they launched a product without taking any customer money upfront. They are here to stay and obviously they don't plan on screwing their customers like the mentioned companies above. Do you really think that a company that was funded by 2 VCs firms will screw their customers? Why can't people see the differences over ALL other companies?

I am with SP, I have a SP10 and happy with it, but the terms and conditions exist for one reason, a buy is a contract and clients are protected if the seller does not comply with the contract. Don't shoot people that wants to get more protection, just tell them that SP is not willing to add that clause but will do anything reasonable to comply with the dates provided.

Buenas,

Pues me gusta la idea pero no acabo de ver la rentabilidad de estos cacharros, por mas numeros que echo con https://bitcoinwisdom.com/litecoin/calculator no veo como se les puede sacar rentabilidad, algunas altcoins dan algo más que LTC pero tienes que sumar exchange fees y o vendes al momento o la rentabilidad teorica nunca se acerca a la real.

No sé no es por trollear, estaba pensando en invertir, pero no me cuadran las cuentas con la cantidad de gente interesada.

Yup that's a know problem they use shopify.com for the shop and it seems that it blocks too much to avoid spammers, so probably your ip is banned even if it is not your fault, try using any proxy, your cell phone or sometinhg like that.

But that doesn't have anything to do with them shipping units, to date they have comply with everyone and big players as anarchystar have bought a big number of units without any problem.

I want to sell a July SP30 preorder from spondoolies-tech.com.
I bought the SP10 April+SP30 July bundle in March with the expectations of the SP hosting price being lower and I am now unable to host it at home, so I need to sell the SP30.

The official hashrate is 5.4Th/s at 2400W but SP has already confirmed that in their initial tests it was at least 5.5 and lately said that it will be over 6.3Th/s at 2700W (https://bitcointalk.org/index.php?topic=521520.msg6468862#msg6468862).
This is by far the best equipment in GH/W ratio, it will be 2U size and fully rackable so it can be easily hosted on any data center.

Spondoolies a new company on the mining hardware market (more info at: https://bitcointalk.org/index.php?topic=521520.0) but ito date it has delivered given a proper client support, fully responsive and they are so sure that they even are willing to bet about it (https://bitcointalk.org/index.php?topic=521520.msg6172707#msg6172707).

This will be one of the first units to be shipped in the first batch, I was sent the SP10 the 3rd day of the April batch shipments (9 April).
July Batch is fully sold and August batch is mostly sold as there was a group buy of almost 400 units, so placing a new order now will be more expensive and you will receive the unit probably a month and half later.

This order includes free express shipping worldwide or 1 month free hosting in their israel Data Center.

The price is 20 BTC

I attach a screenshoot of the order mail.



PM if you need more info.

@spondoolies

Will there be some kind of bonus for the guys who bought the first sp10/sp30 bundle? They payed around 9000$ per sp30 and those are now only 4500$.

These are your most loyal customers, who trusted you from the start and put their money where their mouth was.

Essentially they payed double the amount for only 2 weeks earlier delivery....

I'm sure Spondoolies would have given you similar discount if you bought 250 SP30's, or organized a group buy and sold 250 minimum.

you still have time to buy more by joining in current group buy sale before it closes in 3 hours.  
This would be true if all units went to one customer.
However spondoolies has to manage shipping and payment on a per-customer basis.

I don´t demand anything, i would just like to hear from spondoolies regarding the topic.

These are the most loyal customers who bought their sp30 at~9000$ as part of a bundle.
Early adopters should be rewarded and not punished for making an order.
This is why i ask wether there will be any kind of bonus for these most loyal customers, who trusted spondoolies when they hadn´t shipped anything yet.
There wasn´t even the 10% off chance etc. at the beginning.

While i value the input from every community member regarding this topic, i actually just want a short statement from spondoolies.
I only posted it on the forums because i think many early adopters are wondering the same thing, and i value spondoolies as a company with great integrety.


I must agree that group buy is a bit different, but we are talking about a 50% discount for people buying single orders.
Even if you compare with the SP10+SP30 in store right now you get a 3.300$ discount (or 22%) + one extra hosting month on each machine, even at 3 month contracts thats another 600$. So even with in store prices that's a 3900$ discount.

Even the evil apple usually offers something to the people that bought old generation items when a new one arrives or there is a price reduction.

Also take into account that most of us bought even before the test units arrived, we believed in SP and when the units arrived confirmed they were 100% legit, that group buy would be impossible without us taking the lead and adding trust to SP.

But as said, no one forced us to buy and we did on our own, so I don't demand anything.
