KanoPool since 2014 🐈 - PPLNS and Solo 0.5% fee - Worldwide - 2435 blocks

Block by blockmines!  With all the posts about where we stand on block count it's good that a block drops in

This is our 1st of BLOCK FRIDAY!

Sure is! . It isn't Friday where I'm at yet though.  

UTC clock...always think UTC when thinking about the pool or BTC

Then the dates on the Blocks Page and the Rewards Page will make sense and match up.

I try to think in Icelandic time zone. I am in EST/EDT and Kano times are about 3 hours ahead of mine.

The headers all say "UTC" also

Just got notification that my two new avalon miners should arrive Monday. But my hosting place just informed me that they are full. Does anyone know of any reliable hosting with available space, preferably here in the US. PM me so as to not tie up the thread.

Did you have to pay in BTC?
i got my first miner few weeks back and paid by wire transfer but now they want btc payments only...

I did pay in BTC. But that is my preferred method. I didn't even ask about alternate forms of payment.

As for the miners, I talked to my hosting place and he's gonna squeeze them in. So, hopefully they will be up an running on the pool on Tuesday.

I got a reply from Canaan. It appears they are very busy with orders right now. It also appears they will not have any new miners to ship until August 23, 2017.
I had been waiting about 2 weeks after trying to place an order and wanted others to know about the situation in case they also had tried to order from
Canaan recently.

I must have gotten my order in at just the right time. They shipped within a couple days after I ordered them. :-)

Still wanna order 4 or 5 more though, but will have to wait until I can track down new hosting.

Hi all.

I need some help with this transaction: d388e88859010909f84aafe41a931d88fb738732818b21c58137f7f60369e84a

Thus transaction have been stuck on limbo, and don't get confirmed after 3 days ago...

Something to do with this case?

EDIT: I'm running an full node on bitcoin-core 0.14.2.

Use this bro and it'll get confirmed fast!

https://pool.viabtc.com/tools/txaccelerator/

That's worked mah man, next time I'll pay attention on transactions fees value.

I tried that yesterday for you, but than he said tx fee to loo, I gess there where more tx in the mempool then.

And another one!

Oups no orphan 

[kano]

And another one!

It was another Stale - but I'll leave it marked as an Orphan.
The winning block by btc.com was from inside China and was also slow getting out - I get the impression that even the Fibre Relay isn't always very fast at getting blocks out of China either.
The 2 nodes we have inside China for block propagation were even on opposite sides of the orphan fork to each other.

Everything we have outside China was on our side of the orphan race, but I'd guess that most other pools were also working against us due to the share being stale.

What happened this time, is that the code in ckpool that calls the precious block function that I harassed the core devs about actively switched us to our stale block.
The idea behind this is that if we get a stale block a few seconds after the network has seen a block, we'll switch to it instead.
Our chances of winning the orphan race then end up being directly related to our % size of the bitcoin network (and getting a double block), since no other pool will be working on our stale block.
It doesn't matter which side of a single level orphan race you are working on, coz it's only the next block that matters, so in this case we were hoping to get a double block and thus win the orphan race and get everyone else on bitcoin to switch to our block(s) but alas we didn't get a double to make it happen

In general it's actually a pretty bad idea to do this for the sake of network convergence, but considering some of the worse things done on other pools with empty blocks and SPV/SPY mining, it's certainly not the worst thing we could do, and we can win a double block once in a blue moon (instead of it being a stale block that effectively should count as nothing since it shouldn't really exist)

Edit: and just to make it clear about it being stale, we switched to the btc.com block at 10:16:43 UTC, and the stale share arrived at 10:16:47 UTC so we switched to that stale block then.

Edit: I'll add a little explanation about Stale vs Orphan in case any don't understand the difference:

1) an Orphan race is when 2 pools mine a block at 'effectively' the same time.
What happens with any block is that one pool gets a block, process it, then send it out onto the network, then everyone out there gets it and switches to it.
The reason an Orphan can happen is that there is a delay between when a pool know's one of it's miners found a block and when the rest of Bitcoin knows about it.
This delay is a list of things: time for the miner to send the share to the pool + time for the pool to validate the share and submit the block to it's bitcoind + time for the bitcoind to process the block + time for the bitcoind to distribute the block to other pools.
During this delay, another pool could also find a block - thus you get an orphan race.

Our aim is of course to minimise our length of that delay which we do in multiple ways:
Faster bitcoind than others, faster block distribution than others via nodes near all the Fibre Relay points, lots of nodes to help distribute the blocks around the world if the Relay is slow or not working, and nodes in China to help get our blocks past the GFW faster.

2) a Stale block is when a miner finds a block after the pool has already switched to a new block.
The reasons are any of: the miner is slow to send the share to the pool due to however the miner works (this isn't uncommon), the miner is slow to send it to the pool due to a slow network or a distant network, the pool was slow switching blocks and sending new work to the miner, or again the miner network is slow getting new work or distant getting new work.

Stales basically count as nothing and under normal circumstances should just be ignored. However with the addition of the preciousblock command in bitcoind (or if the pool wrote their own version of the same in the past as many already did) you can turn a stale into a block if you get a 2nd block on top of the stale block before anyone else on the network gets the block on top of the network block at the same height as your stale.

Thanks for the deep dive explanation on this Kano...I have never seen another op that would be willing to share info like this so openly!

[VRobb]

Indeed, Kano is sensei to us kohai. One of many reasons why we're here!

Our chances of winning the orphan race then end up being directly related to our % size of the bitcoin network (and getting a double block), since no other pool will be working on our stale block.

Do the bitmain-controlled pools do this too?  I imagine this could be more useful for them since combined they control such a large % of hash power.

They've probably always been doing this with their custom network code.
They have custom bitcoin network code to do things like SPV/SPY on all their pools also, and I've no idea what else they do that people don't know

Great explanation and insight, thanks!

Not in the US. Iceland must have nice cooling ...

I've been in touch with them recently and they only do 30KW or above, which means at least ~20 or so S9's.

[firetreeactual]

Cryptoboreas is expecting to increase their capacity this month. There's a waiting list. Probably ought to get on it if you're serious.

Meh - another typical technophyte.
This is old news that appears in articles about bitcoin all the time ... I've seen ever since I've been in bitcoin for the past 6 years
They like to make up the false accusation of bitcoin only being used for crime.
To be blunt, he's simply an anti-cryptocurrency troll, and he clearly doesn't understand bitcoin.

Well, pray tell me, what has been the motivation of every drug lord, human trafficker, hit man, robber or any other list of nefarious people for the past years?
Dollars. So we should get rid of them right? They have no other use?
Dollars are the prefect example of how to hide where you got them from.
If you walk down a dark alley and beat someone up or kill them, take the dollars in their wallet, is there going to be a single shop anywhere in 1000 miles of where you did that, that will not accept the dollars you stole? Of course not, none of them will know this. Yes dollars are evil

Bitcoins are way easier to track than dollars

Since bitcoin also allows people to do something that dollars wont allow you to do, transfer monetary value to anyone anywhere on the planet who can accept bitcoin, it ranks above dollars in positive usefulness in my opinion.
It removes the boundaries created by financial institutions for their own gain.
You can of course also store value that no one else can take from you.
... and that's JUST the beginning.

Already people are offering services that you can supply with bitcoin, that you cannot supply with anything else:
