Hi there,
I have been away from mining for a longer time. I opened a new account but was wondering if my original account "disclaimer201" still exists somewhere at Slush? I think I lost it and access to it when the pool website switched to the new design.
If it's gone okay, but it would be nice if there was some way to retrieve it. On top of the fun, I also discontinued using my old mail address, but I could reactivate it just for the purpose of recovering the account, if possible.
Thanks, happy new year 2020 to everyone and good luck mining to all!

And again yesterday.
They found 2 blocks back to back 25 seconds apart. But the 2nd block had just the coinbase transaction.
There were transactions in the mempool at the time.

Twisting the knife a bit.
Look another empty block # 607,275 yes it was quick, but 14 seconds should have been enough time to get some work done. At least you would hope it would.
Might be time for them to retire the old 486 that they are running the pool on and get a nice new i7 or something.
That or I don't know, update the code.
The next block was 23 seconds after their block and had 185 transactions in it.

Alas this is FUD - completely
Firstly, there is no "Stratum V1" it is simply just "Stratum"
The processing time to calculate the work is in microseconds or nanoseconds.
The Stratum data packet size to send full block work is smaller than any standard internet data transfer packet size.
The Stratum data packet size of full block work is typically less than 1400 bytes.
So the extra time would certainly be less than a millisecond and probably less than a microsecond.
So they are simply using FUD to make people think that it matters in Stratum, since that extra amount of time is effectively irrelevant.
HOWEVER, their pool specific changes to Stratum, will make this data packet MUCH larger.

They might not want to generate empty blocks, they might not even be trying to. They just are.
-Dave
This could be the case but it's still a poor excuse not to improve. Their entire service is based on mining blocks and the transaction/rewards to be as profitable as possible for their miners. Transactions are the biggest reason for a miner to choose a PPLNS pool, so not doing everything possible to avoid empty blocks is just letting down your clients. On the flip side of that Miners exist to process these transactions, so if there is even 1 in the mempool it should damn well be in the block. I haven't been on slush for quite some time, but I think the problem has been they are big enough they don't care. There have been a lot of complaints about things like the merged mining rewards, and nothing has come of it. Unfortunately a lot of people just get complacent and don't reevaluate often enough, and if they are still make mad bank on the fees for the blocks mined without facing any real consequence where's there incentive to improve.-Dave
Well, they ARE doing something, just maybe not what you were expecting:
Quote from: https://stratumprotocol.org/#empty
| Empty block mining elimination In Stratum V2, it is equally as efficient for pools to send full blocks for miners to begin working on as it is for them to send empty blocks (i.e. blocks that don’t contain any transactions). Since there is no extra delay caused by sending a full block, the incentive to send an empty block is eliminated. | Stratum V2 No extra delay to send a full block vs. an empty block. | Stratum V1 Slower to send a full block than an empty block. |
You could say they conceded defeat and decided to address the issue at the protocol level between miners and pool rather than within the pool itself.
Discussing V2 probably deserves its own thread, i wonder why they haven't started one yet. The proposal is still open to change and even a large Chinese pool has shown interest in implementing it.

Well, there you go. 250 blocks is at 98.13% now.

1 block in two months? Do you even pool? Maybe Slush can hire you to run their servers or something
Quite well in fact. The last 3 months of stats, have more blocks than expected, sure not a lot of them but that's not how you need to look at things when comparing pool size and earnings. That one block was equivalent to something like 26 days of mining for me elsewhere, and another one will still give me a damn good payout. Though given your signature I'm sure you're aware of the advantages of his pool. A lot can change with a few people waking up and realising their 100PH or more would save 1000's in fees and non-empty blocks if they moved over to a pool with hella good support and infrastructure. It's obvious I moved most of my hash away but still have some on Kano's pool, and if things work out, I will move it all back in a heartbeat. November 19, 2019, 09:07:29 PM
So yes indeed it certainly must be "they don't care"

I didn't say it was an excuse for them not to improve. IF it's anything I listed it's a WORSE reason not to improve.
Nothing was particularly difficult to fix. Hardware is simple, to stressed add more. Configuration check around till you find the issue.
I started on slush a looong time ago. Left and never looked back. As you said between the merged mining and things like this it looks like they just don't care.
-Dave
It's central to how the pool code works, it must work correctly every single time, it must generate a set of data (work) based on the transactions returned by bitcoind, to be sent to the miners.
It is the same base work to be sent to all miners (as slush also said in his argument about why work difficulty was not part of the strartum work data sent to the miners) that then a minor addition is added to differentiate the work for each miner.
If instead they have extra code paths to generating the work, then indeed they are purposefully generating empty blocks, since there really is only one way to generate it properly - based on the transactions available in the mempool.
So yes indeed it certainly must be "they don't care"

So ... I had a discussion with gmaxwell about ... a while ago ... and he said that the large pools don't purposely make empty blocks any more since it's no longer necessary due to bitcoind being fast enough to not need to do it
(though my pool has proven it was never necessary anyway by never having empty blocks, due to never ignoring all transactions if any are available)
Anyway, today slush produced an empty block 603351
They also found the block before it, 603350.
Now when they found block 603350 and 603351, my bitcoind debug.log shows:
i.e. there were at least 8755 transactions available before they found block 603350, of which they used about 2500, and over 6200 transactions available for block 603351 after processing block 603350.
i.e. they purposefully created an empty block 603351 value 12.5 BTC instead of it being at least 12.70234402 BTC and using over 2400 transactions.
So I beg to differ with gmaxwell about his claim that slush pool doesn't code to find empty blocks during a block change
(though my pool has proven it was never necessary anyway by never having empty blocks, due to never ignoring all transactions if any are available)

Or, they are running hardware that is stressed to the max and cannot keep up. Or they have something very poorly configured.
I believe in the concept of never believe people are doing something wrong deliberately. It's usually just incompetence. (Look at the Trezor vulnerabilities)
They might not want to generate empty blocks, they might not even be trying to. They just are.

looks like they pool hash and point it to slush pool but have a diffrent payout system.
Look at the block explorer on their web page and compare it to slush pool blocks
Identical ?? or what are they doing ?
