Yeah... I typically go with NH/WH simply because their prices are usually better. I like MRR because you can specify multiple pools to fall back on should your primary go down, and you also get a more precise control over the actual time you're hashing. When you rent a rig for 12 hours, you get it for 12 hours.

I also like MRR because looking at the different available "rigs" you can determine if theyre S1s/S3s/S5s/S7s/etc generally.

So you can make sure you only rent a pile of S7s/A6s if you want (at least best guess) where with NH/WH you get what you get.

But I usually stick to NH/WH because they're cheaper as Jonny said.

7 A6... 5 up and running now, 2 more coming from the group buy. The S3s are sitting on a shelf in my basement.

Jonny how many A6's will you be running? You put the S3's to bed?

I have never rented hash before and just spent all my coins on the new Avalon6, but I think I could get into renting (gambling essentially). I'll have to let my wallet recoup and then give it a shot.

Seems NH/WH is the most popular, followed by MMR. Do most folk at this pool use NH/WH?

Good luck! May the block gods be with us and bless us with at least one, but hopefully more blocks

I sent him a PM...

Oh -- and I'm trying the NH thing again -- it appears to be working this time!!!

Looks like Johnny is going for it as well...

I got in on that group buy, too, the price for a new Avalon6 was outstanding and I couldn't pass it up. He's sending the coins very soon, so I think it's too late to get in on this one.

More hash for me, need MOAR!

Oh yes that controller.

Yeah super super simple.

The nice thing is you only need one if you have a couple of A6s. A single controller can handle quite a few (~12 or so last I recall).

Right now I have an extra laying around because I didn't need the second one.

How do you get in on those group buys???

Also -- how hard is it to buy and setup a controller???

Thanks...

As bctmke posted, you look at the Group Buy forum to see if anything is running. If you want to get in on the Avalon buy, post there, or PM Phil to see if he's already sent out the payment.

Setting up the controller is exceedingly easy - especially if you get one of the Avalons in the group buy. Everything is already setup for you. You just plug it in and go.

If you buy an Avalon on your own, and it doesn't come with a controller, you'll need to pick up a Pi and an SD Card. Then you just flash the card with the image (BlockC image is setup for DHCP) and you're good to go.

Group Buys - just watch the GB forum (https://bitcointalk.org/index.php?board=76.0) and follow the rule set by the group buy creator

Regarding the controller - can you provide some context?

So I ordered a couple Avalons from Phil's latest group buy. That will bring my total to 7

. More hash for the pool.

Speaking of that... now is a good time to get your rental on and hit the block! Hit it before 110% of expected shares and you'll get a nice shiny bitcoin from me as a bonus. Better hurry, though... once we cross that 110% mark, the bonus goes down to 0.9BTC.

I thought about it - but I think I'm saving my BTC right now (outside of rental spending / etc) for whatever sidehack comes up with

To answer your first question, the estimated next difficulty doesn't use any metrics from the web at all. It's a simple calculation using nothing more than the current block difficulty and network hash rate as obtained from the bitcoin core...

Code:

2^32 * diff / network hash rate = expected time to block
next diff = diff * 600 / expected time to block

I think there are better/more accurate ways of estimating the next difficulty (e.g. looking at number of blocks solved per day vs. expected number of blocks to be solved), but I don't know how much effort it would take to change or it it's even worth it. But I can say with confidence that the next adjustment will not see a 182G diff like the dashboard currently predicts. Wink

There are indeed far better ways of calculating it... but I've not implemented anything of the sort. Perhaps if I get the time, I'll provide a more accurate calculation of estimated next difficulty

Where does the dashboard get its info for estimating the difficulty after the next adjustment? As far as I can tell it does not use any of the available metrics on the web, as it's estimate is way way off.

Also, is there a real-time CDF or luck calc for the current round anywhere? On dashboard I see percent of expected shares, which generally conveys that info, but I was looking if it was shown anywhere else.

Thanks.

There is no realtime CDF or luck calculation. Only current shares and percentage of expected shares is shown.

If you aren't using port 3334 NH will give you a warning when it tests the pool.

It's no big deal. Port 3334 just clears that out

The port is there and working, for sure. NH would have reported the pool as dead if it weren't able to connect. You can always test out a pool prior to creating an order. Login to NH and go to "Account -> Create Order". In the "Pool Details" section header, on the far right you'll see a link that says "Pool verificator". Click on that and you'll get taken to a screen where you input all the pool details. Testing my own pool:

Code:

Pool host: stratum.bravo-mining.com
Pool port: 3334
Pool user: jonnybravo.rental
Pool pass: x
Algorithm: SHA256

Resolving pool host stratum.bravo-mining.com... OK
Establishing connection with proxy... OK
Establishing connection with pool 45.79.191.20:3334... OK
Sending mining.subscribe... OK
