Running 50+ instances of bitcoin?

[altcoiner-]

What would it take to run 50 instances of bitcoin

This is theoretical, but I want to put it into practical use in the future

You will be needing multiple servers for such an infrastructure. A Bitcoin node can get quite heavy, it can even eat you most of your computer's resources even if you have a pretty powerful one. Major altcoins also consume quite a bit of resources, and other smaller altcoins add up... Don't count on a single server for so many things.

What would it take to run 50+ alt coins as well as Bitcoin daemons on say a VPS or even dedicated server?
Is it possible to create a payment system with this many currencies supported, all from one server? Or would you need multiple?

This is theoretical, but I want to put it into practical use in the future

The best service to ask something like this would be Shapeshift. They will give you a better answer than a theoretical one because their services is based on accommodating and holding many cryptocurrencies. Plus they have to make everything running well and be stable every day, all year long without any down time if possible.

Search the service announcement thread for Shapeshift and start asking there. From there maybe the could refer you to their tech people or maybe even their developers.

you need more than a couple of dedicated servers to run 50 plus altcoin daemons and bitcoin core, if you are planning to just host the wallets,then you can do it with a budget dedicated server from ovh,for security reason i suggest you run all the wallets as a separate user,security is the major concern if you are planning to store a huge number of coins.In short , it is practically possible to run everything with a dedicated server.

I think it would depend on the server and the alt-coins and the rest of the software you intend to run.  You'd want to beware having hot wallets on the server of course.  But with a generic selection of alts, plus bitcoin, one could probably handle it, IF it was a server like one of these:

For example, a 224GB RAM, 32 Core, 500GB SSD (or 2TB SSD) server could probably handle it. A server like that would not be cheap (around 1700/month at DigitalOcean).  At Amazon EC2 (32vcpus, 244 GB, 640GB SSD range, d2.8xlarge would run about 23616/year).

So for someone with the money to invest in it, it is doable.  A low-end VPS with 4GB of RAM or even 8GB of RAM wouldn't be a machine I'd try it on.

How about running ETH, XMR and BTC all on the same server?

You would need a hell of a beast.

can you post the full /proc/meminfo output? (if you don't mind) or can you tell how much is used with the 350 instances running? i am also curious about how your

Code:

df -h

output looks. did i understand you correct?: 350 btc-instances in live-net?

thank you,

You surely will need more than one server if you want to host such an enormous project. Putting aside the hardware power that it would need, you cannot host a financial system from one server for security reasons. You need at least three dedicated servers to do that.

[Evil-Knievel]

The better, more robust and cheaper option would be to get 50 digitalocean droplets

You need to go here: http://lbc.cryptoguru.org:5000/download, download the 64bit version, and run

Code:

./LBC -c 45 -t 3600

 

Ok, maybe not even for an hour, but I seriously would like to see what happens. While I have some machines with 1TB RAM here, none of them has 120 cores.

I take it, your machine has 120 logical cores (that is - with hyperthreading) and therefore 60 physical cores.

Actually, I have 4 physical CPUs which have 15 physical cores each. So 60 physical cores and 120 cores with hyper threading.
And I have 6 of these machines here   You could probably sell these machines and get a couple brand new Ferraris for it!

As I suspected.

Holy Sh...!

I guess 12 hours of operation would shoot you straight to the top of the Top15 (http://lbc.cryptoguru.org:5000/stats) and I believe we would see the Pool bounty claimed before Midnight GMT...

A couple of Ferraris couldn't do that.

The pool bounty is 0.00666666 BTC? 
What is this project doing, by the way?

Yeah - well... 

After 1AKKm1J8hZ9HjNqjknSCAfkLR4GgvCAPjq (0.00006660) and 1TinnSyfYkFG8KC3gZ72KpYxBXsxSadD8 (0.00066600) which have already been found/claimed - it's now this.

What is LBC?

The "Large Bitcoin Collider" (LBC - a homage to LHC) is a distributed endeavour to find Bitcoin collision(s) by systematically creating addresses to known private keys and checking them against the list of known BTC addresses with funds on them. In the unlikely case of a collision, the funds on the address in question would become accessible to the collision finder.

I wanted to do something different - but please in case of interest, let's continue here: https://bitcointalk.org/index.php?topic=1573035.0
as I believe I've hijacked this thread for too long now.

So to add something to the topic here:

Running a bitcoin node, requires

• at least 100GB hd space for the blockchain
• at least 1.2GB RAM (*)
• on average 30% of a Intel(R) Xeon(R) CPU E5-2630L v3 @ 1.80GHz core

Litecoin is not as stern. Don't know about other Altcoins, but I wouldn't want to run 50 full bitcoin nodes. :-P

Run 68 istances while ago. no issue. need some high drive space.
