NXT :: descendant of Bitcoin - Updated Information

[redsn0w]

Huh! My testnet coins and assets have disappeared. Was there a reset of the testnet or something?

What is your TEST address number ?

Hi , I sent you 1K TestNext .

thanks

[landomata]

I'm a nobody here, but I also kindly ask you to calm down.
Don't befoul this thread with your aggressive wording...

Smaragda has been in the trenches and today was the 1st time i've seen him get worked up....so i'll let it pass.

Why don't you ask him why he's worked up?

[ChuckOne]

below are from the latest Bitshares X whitepaper:

A recent entrant to the Proof of Stake scene is Nxt which claims to be 100% proof of stake and does so with a process they call transparent mining.
With transparent mining the network deterministically selects who gets to produce the next block. If this person is online at the time then they get an opportunity to earn transaction fees. Otherwise a block is produced by the next in line.

The problem with existing proof of stake systems including Peercoin and Nxt is that they dependupon a subset of users that actually choose to dedicate computational power to mining in aneffort to earn income from transaction fees. This creates two classes of users and significantly reduces the percentage of the money supply used to secure the network. Additionally both of these systems suffer from the potential that a large stake holder could perform a denial of service attack by refusing to include some or all transactions.

how do you think the comments about NXT transparent forging?

Seems they r right, we should implemented forging power leasing to get rid of such the issue.

It related to what I said previously here: https://bitcointalk.org/index.php?topic=364218.msg5034359#msg5034359

How does a node decide which transactions to include? I think the answer is: the node decides itself.

So, when an account leases forging power to a node, what should prevent that node to mis-use that power?

This creates two classes of users and significantly reduces the percentage of the money supply used to secure the network.

Why? Here we see no explanation but just a statement of "fact" (or in other words "bullshit").

Additionally both of these systems suffer from the potential that a large stake holder could perform a denial of service attack by refusing to include some or all transactions.

They seem to have overlooked the "penalty" for not forging here.

Not forging does not mean, not including certain transactions.

Man, Wesley your client is so SLICK

Love it. Wish I was buying real assets..

[ChuckOne]

The White Paper has some interesting ideas:

https://docs.google.com/document/d/1RLcjSXWuU9vBJzzqLEXVACSCdn8zXKTTJRN_LfoCjNY/edit?pli=1


We should use more tangible terms when propagating NXT. People need tangible words and concepts to reach a real understanding of NXT.

I really find the term "BANK" very inspiring: in fact the NXT network is a decentralized BANK.

I bought some shares, but now I want to issue my own, only have 899, can someone send 5k so i can mess around?

Fear that the leaser will take the power back.

Anyone got 0.7.5 successfully running on a RasPi?
Mine is crashing everytime because of memory issues.

I have RasPI running with 0.7.5. Starting with java -Xmx150m.... "Scanning Blockchain" take ~8-9 minutes. Opening acount works also, forging too.

So it should work with model A and B.

HEY! does this look like I only have 448180k physical ?!?!?!?! That will be something to check up on!

[ChuckOne]

So, when an account leases forging power to a node, what should prevent that node to mis-use that power?

Fear that the leaser will take the power back.

That should not suffice. There could be a business model made on top of this:

1) bad node tells forgers 'u get a bigger slice of the profit when u support me'
2) bad node does only accept transactions with big fees
3) people will pay

You could argue that in that case people will cash out and move on to another crypto-currency or NXT clone. That is true if NXT is young and nobody depends on it as it is the case right now.

However, if NXT is mature and a lot of services depend on it, nobody can cash out that easily and will feed the scheme

How much RAM you can effectively use depends on the ARM/GPU memory split.

Either run raspi-config or edit /boot/config.txt (gpu_mem) to set the actual memory chunk that the GPU gets.

With the minimum amount of 16MB for the GPU, which makes sense because I never use the Pi with a display, I can effectively use 496948 KiB of RAM.
