Out of curiosity what is the theoretical max?

Address balances are stored in the database as 32-bit unsigned integers, therefore the maximum value should be 4,294,967,296 KST for a single address.

Interesting. How exactly does krist work? It sounds like bitcoin for minecraft.

It works almost like bitcoin, but funds are transferred instantly.

Wait this doesn't look right: (date)

Yeah, this was reported to me last night. I'll look into that now.

Edit: I have fixed that on the test server. It will be fixed in the live version soon.
Edit 2: Fixed. There has also been internal changes to add address authentication. Now, an address can only have one privatekey bound to it, meaning you can mine at addresses all you like, you're gonna have to find the exact privatekey used to make the address

I'll type up a further explanation of how this works soon. But thanks to this, you shouldn't have to worry much about address security.

Hey! That's a good idea. I should've thought of it myself.

I'm glad you didn't, because I'm certain your implementation of it would be some of the worst written code in history.

as long as there arent any plain private keys in the database, thats fine. i hope you just used another hashing algorithm for that.

They are hashed and salted with the address.

Would the work go down if everybody stopped mining?

No, only if someone mines a block.

Kristwallet needs to removing spaces from the krist names, i just made it crash

[Creator]

And the difficulty?

Same thing, different name.

[Lemmmy]

Changes to work (difficulty)
We have changed the work algorithm, so now the difficulty to mine a block should adjust appropriately with mining power. This is still in testing, so please let us know your feedback on this.

The new algorithm is like so:

var seconds = (time - lastBlock.time) / 1000;
var targetWork = seconds * oldWork / 60;
var diff = targetWork - oldWork;

var newWork = Math.round(Math.max(Math.min(oldWork + diff * krist.getWorkFactor(), krist.getMaxWork()), krist.getMinWork()));

Little explanation:
The work is adjusted so every minute a block is mined it also never goes below 500 or above 100000

How can you modify difficulty?

You can only do this indirectly by mining blocks or not mining them (so you can't really modify it)
Btw, this works almost exactly like bitcoin, and there are multiple articles on the web explaining bitcoin.
Hm, you should add smoothing like

var seconds = (time - lastBlock.time) / 1000;
seconds = seconds * 1.5 + lastSeconds * 0.5

Because now mining a block after a hour would make the work sky rocket, the next block would be solved in >1s and the work would drop like crazy

How does Krist make it more difficult is what I meant.

It changes whenever a block is submitted according to the algo I posted above.

Will look into this. We were also considering simply clamping the seconds, but this could also work. Thank you!
