Topic: [ANN][MULTIPOOL] ScryptPool (BNL) - Scrypt ASIC friendly PoW and PoW/PoS hybrids (Read 7526 times)

Hey all!

It's been awhile since I wrote here, so it's time for a little update.

First of all, I apologize the domain is down, site should be up again any day now.

Now that we got that out of the way, let me tell you a little story. As you know, I have operated ScryptPool for quite some time, about two years!

It has been quite a journey and a lot of things learned. Which is why this latest maintenance has been going on for a long time as well.

I decided to take everything down with a notice of 3-6 months downtime, so that I could reorganize my infrastructure and allow it to scale in all directions.
This was not an easy task, and it involved quite a bit of research, trial and error and hardware investments. Those were some very long days.

Lessons learned:

1.) Things break
Everything from software to hardware, and when things break, they become unavailable and other problems start to happen as a result.

2.) Power failure
As a hobbyist, I'm not able to give the pool power redundancy at this point. (*)

3.) Software failure
Wallets crashes, hangs or lags terribly. What if I could spawn a new instance, and aid that wallet, seamlessly. (*)

4.) Scheduled tasks
Even though crontab is quite a powerful scheduler, it simply isn't enough for a system like this, where a lot of things are going on at the same time. (*)

5.) Management
A system like this is very complex, it consist of many small tasks that can stop or break. I spent several hours night after night fixing tasks that had failed. (*)



* The solution *
Micro cloud. Now what the heck is a micro cloud ? Perhaps it's not the correct term. *shrugs*

To me it's a stack of microcomputers that are providing CPU and RAM in favor to a cluster.

What the heck man ? I know right..

Research begun, and after a few months it was time to take theory to practice.

I took 4x raspberry pi2's and arranged them in a small cluster (depicted in the link below).

RBPi's: https://twitter.com/sioghi/status/777919980163723264

Although not very pretty it was fully functional.

At this stage the total resources was 4 CPU's (16cores) and 4 GB of RAM across 4 nodes.
The cluster technology was still unstable and depended on 3rd party modules and very hard to configure and expand.

A few more months passed, spending night after night doing research and test deploying a couple of wallets in the test-cluster and messing around with scheduling and isolation (Shit's gotta be secure!). The containerizing software matured and the features from the 3rd party modules became native.. It was finally time to notch it up a bit.

I ripped the test-cluster apart and ordered new parts...

Now we wait... and wait... some parts arrive and I jump with joy, not really, because I still had to wait on more parts, screws, cables, etc. and wait, and wait some more and finally...

I had enough parts to start putting them together: https://twitter.com/sioghi/status/792047122682155008

Those are 12 compute-nodes, all raspberry pi3's with a total of 12 CPU's (48 cores) and 12 GB of RAM. Each also have a 16 GB class10 micro sdcard to host the OS and node-agent.

Having that said, there are still more things to be done.

I tweet about all kinds of cool cloud computing related stuff.

All the best.

ASC would like to have an update if / how mining resumes

interesting multi pool, will drop by once the rebuild has taken place.

Hi
Can't login since few hours to withdraw my coins

Hello users!

I need to take the pools down for extensive maintenance to bring ScryptPool to a whole new level.

Downtime will start 2016-07-01 and will last for 3 to 6 months!

Website and chat will be online during downtime but mining will not work.


Below is a simplified action plan:

* Stratum will be taken offline, please set up backup pools (Check out http://hashnova.com/) for your workers to minimize mining downtime.

* Wallets will be upgraded rescanned and reindexed.

* Everyone will be asked to cash out their coins, I want to see 0 balance on everyones accounts.

* Our entire infrastructure will be torn apart and our new fysical and logical infrastructure will be built.

Important:

Make sure you have addresses specified for every currency, and set them to daily payout.
Any balance remaining in a wallet after termination will be considered as a donation to the pool.



What is the meaning of all this ?

To serve you with a high quality pool we have done alot of research and testing, and come to the conclusion that our current system just isnt good enough.

There are simply too many design flaws that prevents us from scaling further, which is why you see wallets drop out of sync, drop connections, fork etc.


Best regards,
Bejjan

1) The fundraiser has nothing to do with your account on the pool.
2) I am quite tired of all your profanity, would you like me to share your emails with the world ?
3) I blocked the accounts as a security measure, as the messages delivered in the chat in your name was of such nasty quality I really thought your account was compromised. I see now though, that it was you afterall.

I have unlocked both your accounts.

Withdraw your coins from the pool, and go somewhere else, you are making my other users upset.

I had GLD coins! Where did my coins? Why today you shut me access to my account?
Shit! You shut me access and stole all my coins! I love you in the ass I will be!

if you are adding coins to your mining pool,

Hello!

I have started a fundraiser campaign to rescue Novaexhange.

You can see and follow it here: https://www.scryptpool.com/novaexchange

ScryptPool has donated 9 LTC to help the cause.

Best regards,
Bejjan

Because it is scrYptpool.com not scriptpool.com

Best regards,
Bejjan

why from my mobile when i try bringing up scriptpool.com  i get the message the domain is for sale

Hi,

I am Yan Crevier (Soltantgris) from Auroracoin devteam, and contact you to make sure you already updated your client so you get ready for the hardfork coming may 1/may 2 @block 225000.

You can find the latest clients there : http://auroracoin.is/

If any question, feel free to ask, or connect with skype : soltantgris.

Thanks

All working now, well done bejjan. Better luck next time !

Last I heard he was moving wallets and syncing them last night so they should be online anytime, bejjan is a good guy so its worth the wait!

The pool crashed while Bejjan was ill. He's working on it, but might take some more time.

Looks like all scryptpools are down for maintenance .. any idea when we'll be back in action?!

bejjan, please export your pool data to http://poolpicker.eu/table?algo=scrypt. Would be nice to compare and should give your pools more exposure.
Any plans of merge mining Doge, Via, Sys and uLTC?

No, nothing was deleted. It is just a new name, everything points to the same place.

/Bejjan

Were all user balances deleted when switching from https://pool.bejjan.net/?

Glad you like it

More coins on the way, so keep your eyes open!
