Can the code of a hatching code not be modified by a malicious entity to only vote yes for certain transactions? Does that not make it easier to control the network when one hatching node has so much power?
Would a hatching node that only votes no slow down the network? What if there were thousands of them?
What stimulus is there for running a hatching node at the beginning when transactions are minimal?
It seems you have centralized processing to certain nodes. That seems to make it easier for an attack overwhelming the network.

How do you prevent Sybil attacks-- somebody creating a gazillion n-client and/or hatching nodes, and voting themselves lots and lots of new currency?
And how does a node choose a "random" node-- does every node know about every other node? If yes, then how do you avoid getting O(N^2) communication as the number of nodes (N) rises and every existing node must be told about every new node?

I'm composing an amendment to the OP regarding Sybil like attacks and the prevention of them as a few members have raised this point both public and private, I'll be appending it shortly after I've finished up some other tasks. Hopefully that will then give an idea how we handle it.
Selecting a random hatching node doesn't require the peer to know about all of them, or about any other client peers in the system. A voting peer can either select a hatcher from its currently connected peer pool (if there is one or more present) or send a request to a seeder node which has a collective store of all the most recent nodes within the system (as its seeding it is able to do this easily), including plain client peers, hatchers and other seeders. As peers and hatcher connections come in and out of this peer pool, that further massages the entropy of the hatcher selection.
With the voting system it is possible to have many hatchers, all obtaining votes from the client peers independent of each other, and deciding, independently also, whether to create a new currency unit or not. Currency regulation is determined by using the public ledger, so providing that all the hatchers collecting votes are close to being up to date, they will all be working to the same vote threshold.
As the system grows hatchers will be working with a subset of the total voting power in the system, but the required target volume can still be met and held.

I'd like to be a tester as well. If I qualify then please let me know

Currency generation is a collaborative effort between n-client nodes and a hatching node. Each node in the system will cast a vote to a random hatching node to whether to create a currency unit (EMU).

Let's be creative with the name.
Some play on words referring to the characteristic of the coin...

It's interesting. What is required to be a tester?
BTW, I don't understand the voting for creation part.

I'm in, I have access to a lot of CPUs, operating systems, static IP, fast uplink.
Maybe a new thread when the time comes to work on a name. I've always been a fan of something like eGold, as "gold" is something easily translatable into every language that's come across it. "Muslim" was the first thing I thought of with the name.

Ok wow, mass response in such a short time.
Thanks for all the offers of support! I'll be in touch with all of you in due course.
To those with the GPU rigs, at the moment our block and transaction verification code is CPU bound, although we are looking at being able to push some of this work over to the GPU pipes to make the process more efficient. Whether that is at a testable point during the beta, or after the production is switched I'm not sure, but we will continue to run the test network post-production anyway.
The Android/iPhone wallets will be a while off (unless someone decides to write one before we do), but its useful to know who has devices they could test with, so thanks for providing the info.
Anything else anyone wishes to know?

What about name - eMulah - is it final? Name is very important for coin.
Pretty final, Mulah is slang for money, e....well yeah, EMU as a currency abrev gives us lots of branding options. so unless you have a better suggestion?
Any ideas on how you're planning on keeping it CPU bound? YAC had a novel approach, but it didn't take long for people to figure out to gpu and fpga mine it.
Also I get what you're trying to do with the EMU name, but I have to agree that eMulah is kind of a cheesy name for an idea this awesome. I don't have any better idea right now.

Finally something different. I would also like to help test.
May 30, 2013, 06:49:52 PM
I'm in for testing
May 30, 2013, 06:44:46 PM
Count me in as a beta testear! I'm looking forward to participating in this experimental crypto coin.

This sounds an awful lot like a Communist coin...But I'd like to join the beta anyways, comrade 
Well communism is great in theory, problem is regulating the humans. Computers aren't so *fickle* and do as told

Definitely in for the beta test on this, like a few said before, good to see something new
May 30, 2013, 06:04:14 PM
I like to join in the beta test. Tks
May 30, 2013, 06:02:57 PM
You can count me in

I'm interested to beta-test EMU !
Cheers.

Interesting, I would like to participate too.
What is there to prevent somebody to trick the network to think he is running multiple hatcher nodes while he really does run only one?

I'll be editing the OP with details about the prevention shortly as its been raised a couple of times
