Sparkle Alpha Test Network Live: Mining to be Honored in Real Network

[bytemaster]

I think someone is just burst mining it since the difficulty adjusts so fast.  That hard fork to fix that is still a long ways away...

EDIT: Difficulty is also adjusted every block, but based on the average time of the last 1000 blocks, so someone dumping AWS instances on it could mine quite a few blocks before the difficulty adjustment caught up with them in each burst.

Good thing this is being tested.

[Frodo]

Yeah me too. With so low block times there are constantly forks.
When I think that I'm on the wrong fork I just delete the downloaded chain. It usually finds the longest chain then.
Not exactly elegant though 

[arubi]

I'm forked as hell.. what's a good node to be connected to?
also, I just saw one node with current_head_block_number": 3685, so I'm guessing you're on a fork too.

Network completely borked

another edit:

Now I'm on this head : blockchain_head_block_num": 3829,

[Frodo]

Looks like difficulty adjusted down. I'm currently on block height 3505.

[arubi]

Is the target still high or am I on a fork?
I'm connected to 8+ peers who all share my block height..

[bitder]

The mining difficulty is not correct. The current situation is that the block times are getting larger.

While mining, it made a transaction I've never requested. Is it expected or is there a security hole and someone got access to my account? Also, it has some garbage in memo.

...

Did you build it yourself, or were you using someone's binaries?

Built myself on Ubuntu.

I get "Qt5quick.dll is missing" error.

[arubi]

So.. how many connections are you getting?
I'm on 4, one of them is the node from the list on page 1.
Blockchain height is 2741 and difficulty is 4194.

Does that sound like the main chain?

edit:
Suddenly 8 connections, a couple hundred blocks missed, difficulty back to 100...
Very strange.

Seems to have worked itself out.

The images are kinda borked, but it works and you can mine. I'll work on it more later if there's any interest.

It doesn't work for me as well...

Try Visual C++ Redistributable Packages for Visual Studio 2013

Tried with Packages but doesn't work for me either.
