Any help? The client seems to load fine, but it doesn't show that I have the 1 coin the online client shows.

I can't mine without this client on my computer working correct?

Check if blockchain of ur client has the same number of blocks as online client does. And check what the last block height is.

U can mine on any node.

Well, I updated my node with a quick fix provided by BCNext. Let's see which fork wins.

How to make the VPS node start mining independently?

Unlock an account on that node and then just close the webpage.

That's easy , but what about security issues raised by some like transmitting passphrases to an online client?

Owner of the node or anyone who sees ur traffic can intercept ur password and steal the coins.

So first part is OK, as I am owner of node.

1) What about the second part? How to make it safer?
2) If 10 users unlock their accounts through my node, and then close their webpage, does that mean my node is mining for all 10 users?

1. It's still not secure if someone sniffs ur connection.
2. Yes, u will be mining for 10 users. But ur hardware won't notice even if it mines for 1000 users. It's a proof-of-stake coin.

[Come-from-Beyond]

When I first opened the local client on my system I've got a timer counting down until I can mine the next block. I left it for 2 hours. I see I've mined a block, but now the timer is gone. Even if I restart the client, reload the page, I see nodes connected to me, but no more timer on the blocks section! This is on build 23.

Does restarting the node solve the issue?

Someone sent 1 NXT with 211 NXT fee. http://88.198.210.245:7876/?request=getTransaction&transaction=11208448953589580614

Let's support miners with higher fee. While the network is not so big we r subject to 51% attack, miners save us.

How do you start mining so I can know if it is affecting that?

If there is more than 15 second difference in time then other nodes will disconnect u.

Unlock an account u want to mine with. Open Block / Recent blocks widget. U should see a timer showing how much till next generated block.

If it's a new account than u must wait 1440 block (~1 day) before u be able to mine. That was done as protection against an attack devised by Cunicula.

[svost]

I shall ignore it?

Ah that would be it. Thanks.

U have to use Nxt API. I do it such a way:

1. I notice block id in Recent blocks and do http://88.198.210.245:7876/?request=getBlock&block=6655037457003426334
2. Then I look at "transactions":[] ("11208448953589580614" in our case) and do http://88.198.210.245:7876/?request=getTransaction&transaction=11208448953589580614

Bitcoin is crashing. Is it a coincidence?

Yes. Account id is used for that.

Looks like your node is offline?

I have same problem.
I locked account on my http://localhost:7875/  and what now? Should I have it open for 1day? Or it is enough that wallet address was created and after ~1day when I open it again will be I able to mine?
Do I have to do anything else or for ~1day time from now it is all for me?

how to mine?

is it need any special software ?

Yes. Account id is used for that.

Looks like your node is offline?

Yes. 256 Mb is not enough, but I can't get more without changing IP address which is bad coz my node is used as a bootstrapper.
