People have made computers, memory, calculators, whatever with Redstone in the game of minecraft.
Is it possible to do ripemd-160 and sha-256 and base-58 with Redstone?

This would be pretty cool.

Thanks!

I bet we don't have any redsnone masters in here.  ;D I've seen some advanced somputers in minecraft, but those are only capable of running basic applications like tic tac toe and such. This one is the most advanced I'm aware, please correct me if I'm wrong.

But from what I know, there is a costumizable Random Number Generator for command blocks. https://imgur.com/a/xrz66

Someone could try costomizing this and see how far it would get him.

Also you can make a Random Number Generator with vanilla redstone.

Source: I've tried using some of those (not for the same reason you are aksing). I failed gracefully but I've still hundreds of playhours with minecraft, most of them from the early stages of the game.

Let me get this straight.. this is a computer built in a computer game.

If so.. that is pretty cool.

For all you know, every computer you've ever used is a computer built in a computer game.

I try not to think about the fact we might just be a simulation.

For Bitcoin or any other cryptographic purpose, you want to make absolutely sure that your random number generator is solid:

http://en.wikipedia.org/wiki/Cryptographically_secure_pseudorandom_number_generator

Flaws in random number generation have made certain Bitcoin applications vulnerable in the last year or two.

Obviously if you don't intend to use a generated key for anything serious, it doesn't much matter how good your RNG is.

I think it would be less of a "I will use this keyset to store thousands of bitcoins" and more of a "I created a bitcoin keyset in Minecraft" :P

I should certainly hope so!

But I felt it was good to put a warning out there for anyone who just doesn't quite get it...

All these cool ways to mine bit coins are not at all efficient but more of a novelty item. Just like that way to mine bit coins using pen and paper.

On a semi related note on simulation - would using a steganography tool to steg offline wallets/key/password work or be a useful idea?

This is really fascinating stuff. I just don't have the time for other digital world outside of bitcoin. It would be great if you guys could keep this kind of topic fresh.

This would not be a good idea. minecraft is not open source so you do not know exactly what you are running when you create and store a key minecraft. Basic security principles state that any software you use  to create a private key and to store a private key should be open source so it can be reviewed by the community

I agree. You have the potential to either lose your private keys or they somehow will be leaked to either another user or leaked to the maker of minecraft. You should always generate your keys yourself with a proper RNG

He meant to say that anyone with the cryptography knowledge to make keys in Minecraft would know not to use them to store money.

Yo Dawg... I heard you like computers... lol

We do.

Yep

And I guess it could be possible I mean if it can be programmed why not
Can imagine it trying to mine bitcoins kid :)

I guess this would still be easier with just command blocks. Compare the random number generator to the computers. Which one do you think is easier to make and program?

lol


Suddenly I've got the urge to go fire up Nesticle, Stella, and MAME.

Nobody is talking about mining in this thread but rather about generating keys.

You try to make computer in computer  :o

I bet you need at least 1.000.000.000.000 blocks  ;D
And you computer will explode  :P

How about mine bitcoin with diamond pickaxe  :P

There was a server that would reward you in a bitcoin amount for every block you broke. Not sure if it's still active.

It's is. minecraftcc.com

I don't play minecraft.. That might be a problem.
