... I read that the T9 were more efficient than the s9 in relation to temperature.
...
6 chips less per board will always create less heat.

If you have to ask why, you wouldn`t understand my answer.

But that wasn't the reason for wanting to run away screaming ...
There is a function in all your recent bitmain miners "send_mac"
 https://github.com/bitmaintech/bmminer/blob/master/driver-btm-c5.c#L7764
It connects to bitmain
 https://github.com/bitmaintech/bmminer/blob/master/driver-btm-c5.c#L7683
Since AUTH_URL is:
 https://github.com/bitmaintech/bmminer/blob/master/driver-btm-c5.c#L223
"auth.minerlink.com"
and it sends your mac address, some miner id, and some hash board id string to bitmain
 https://github.com/bitmaintech/bmminer/blob/master/driver-btm-c5.c#L7774
Randomly every 1 to 11 minutes while the miner is running
 https://github.com/bitmaintech/bmminer/blob/master/driver-btm-c5.c#L7783
It doesn't matter what pool you are mining on, it still connects to bitmain

Now here's the real fun part ...
It checks for a reply from bitmain and if bitmain replies with anything containing the word "false"
 https://github.com/bitmaintech/bmminer/blob/master/driver-btm-c5.c#L7755
Then it will abort the checking function
 https://github.com/bitmaintech/bmminer/blob/master/driver-btm-c5.c#L7777
with the message "Stop mining!!!"
But if it fails to connect to bitmain or it doesn't get a "false" reply, it will continue checking randomly every 1 to 11 minutes connecting to bitmain.

Now I wonder why they would have a function like that, there in the code ... ... ... ... ...

I might just block "auth.minerlink.com" at DNS and my router in preparation for when it starts to resolve?

Or perhaps it's just something they utilise at hashnest to manage their miners.

@Citronic: Welcome back!


The Avalons 721s x 120; are mining here at Kano.

The S9s v1 x 108; are mining somewhere else.

Both farms are powered by hydroelectricity at Cryptoboreas Inc., Labrador-NFL, Canada.
Yep, I know just the Avalons are here but I wasn't sure how long they've been here so I just wanted to welcome you back. Maybe you've been back for a while and I missed that (my bad, if that's the case) but good to have you here with lovely Juvia. Smiley Spring is just around the corner (in the Northern Hemispere) so I guess Winter Juvia will be bidding us farewell soon. Mine on.

Well if it's used by hashnest then they are morons (as usual)

The cgminer API has a broadcast option that I wrote in it ... many years ago.
You enable it in cgminer --api-mcast
Then send out a broadcast message on your network, and all running cgminers with it enabled will answer.

Yeah, crazy innit. Hashrate up 30%, no luck at all. Dips a bit and boom. Almost makes you want to mistrust the maths!

Mining since January 2017 those A7s.

They are not Juvias though but Grays; Juvia's main squeeze  Cheesy

Yes, Summer Gray avatar should be coming soon.

Great to see the pool back to her old self.

Amazing Dog you have there, but don't be too happy, since my dog has the same capability to make the sun rise.

But that is slightly different. I was obviously joking 1st of all, but actually perhaps not!!!! It could be some bug or some threshold or limit which does actually effect it. Perhaps with more hashrate the servers are getting overwhelmed and not sending out the info fast enough, I don't know, I am talking out of my ass, but if it is consistently like that, then something is wrong, not saying that is is consistently like that... But.... Basically saying, don't jump to conclusions that it is indeed just bad luck and nothing more than that!!!

A have a question to kano or some other blockchain or db specialist.

I was under impression that once tx is on the blockchain, even an unconfirmed one, then it is unchangeable.
is this really so, or does current soft allow for some sort of "replacement in kind" with the same numerical outputs for currently unconfirmed transactions?

I seem to remember some noise last year about purchasers having a 10 minute window to cancel the tx. Could that window be related to min time a tx sits in the mempool before being permanently added to a block and therefore the blockchain? A lot of small retailers that do take BTC like diners and coffee shops were upset about that because of some folks getting their goods then walking out the door and canceling the tx...

Don't know if that is right but is what I dismember Wink

Would it make sense to try to fork the code and update the miner with a new version that eliminates the send_mac and setup_send_mac_socket functions entirely?
I got booted out of the cgminer team - so don't ask me Smiley
Ask the cgminer guy who bitmain pays for pretty much all the code he writes Tongue

I thought that I read somewhere that it is possible to run a different miner (was it cgminer) on the S9's? The startup scripts also seem quirky and not very robust.

Good idea! A simple entry in the "hosts" file pointing to 127.0.0.1 will do  Roll Eyes

This will do in /etc/hosts:
Code:
127.0.0.1       localhost.localdomain           localhost
127.0.0.1       auth.minerlink.com              auth

An unconfirmed transaction isn't in the blockchain.
It's simply in the mempool of anyone who has accepted it.
From the point of view of it ever getting in the blockchain, it must be in the mempool of (some) miners and they must include it in a block they find (and it must not be orphaned) e.g. a pool - kano.is Smiley

There's also:

1) RBF (replace by fee) was implemented by core - yep many may not realise that you can replace a transaction with a higher fee.
Bad idea in my opinion, but no one got to decide that, core just added it in.

2) Maleability. There is a minor fix for this here already in core for 1x transactions.
However P2SH (3x transactions) is plagued with this due to the design flaws in it.
That's basically what segwit is a poor solution for - poor since it is also full of 'core profit' motivated code, not just a maleability fix.

Maleability means anyone can change a transaction identifier to produce the same transaction result (same inputs and outputs) by modifying something in the transaction that does not depends on proof of ownership of the inputs.

....interesting
I had a tx that was not confirmed for 40-48 hr or so, but i could see it's tx id on both blockchain.info and blocktrail.
Suddenly, it disappears altogether and shortly, but not immediately, there is another tx id and tx is immediately confirmed, but timestamped at the second occurrence. All inputs/outputs are the same.
What could have happened?
Someone just picked up this tx, but timestamped it as a current one?
Blockchain fixed itself? LOL
