Pump. CfB has no answer.

Now, let me think how (within this model) the bad guy grows a fork of depth 2...

Correct. Excuse the wording. I was just discussing with someone the gateway james has in progress and I could see their hard-on.

So for each account we take the first 8 bytes of an SHA256 hash of the "previous block sig + your account #" to get a "base target" (so an unpredictable 8 byte value that changes with every block). We then multiply this by your account's balance and the time (in seconds) since the last block to come up with your "current target".

There is also a "minimum target" value set in order to prevent spam (i.e. we don't want the network clogged up with people broadcasting "losing tickets"). This value is not overly important so I wouldn't worry too much about including it in the model (or just pretend it is a constant maybe).

Note that the time multiplication is really just to "widen" everyone's chance so that it won't take more than 60 seconds for "someone" to have a "current target" > "minimum target" and then broadcast their block.

When considering what is a "better block" time would be removed from the equation (so best "block target" is always the "base target" multiplied by "account balance") so the whole "time" thing could be left out of the model (just want you to be clear how the system works).

#ID PROCESS = top .. and search on java process , take the id of the process and type it in the shell.

AE is only a tool, not a gateway.

I seem to have some config param missing in my raspi - when I start 0.8.1e using:       java -Xmx128M -Xmx480M -cp nxt.jar:lib/*:conf nxt.Nxt

 most of the startup process incl. starting blockachin seems to go well, but it crashes when launching the ui server:

Get asset exchange online and working and both the fiat price and the link between Nxt and gox will stop being a concern.

We need to focus. I need to focus. Thoughts.

BCNext's idea was, speaking of forging incentives, to get rid of transaction fees. The idea is that companies, who use Nxt (as a platform, as their payment provider, as what ever), earn money with their services, and thereby have an interest in running nxt nodes to provide stability for it.

But BCNext doesn't live in fairy land (well, sometimes he does, i think) and knows that thousands of companies will not get built on top of nxt or use nxt right now but in the future. First, we need to provide a stable and secure network to (potential new) businesses before they use it. That's why the first plan is building Nxt as a currency to get a wide adoption. I don't think we are there yet. Only because we know the 2nd plan doesn't mean we have to jump on it. Or should we? And, of course, trust no one, we don't need to follow his ideas, yada yada yada. Well, he is a smart guy. Let's think about it:

We need fees right now to have an incentive for forging (and maybe a better fees structure, like the hallmark idea) and we don't know for how long. But we should also get rid of fees to make it possible for companies to use Nxt. This chicken and egg problem can only be solved with a gradually decrease of fees and give Nxt a kickstart with paid infrastructure for the next months (years, we don't know). Or is there another solution?

If this is correct, we should talk about how we will come to a consensus about decreasing fees in the future. And our infrastructure committee (not in place yet) should go to work on nerdy things for stability, 1000TPS, .. as soon as possible.

Also, how do we prevent spamming when there are no fees? Maybe we should have different fees on different parallel blockchains.

---

Penalties. At least it was part of BCNext's idea that we should penalize accounts who don't forge. I don't see a problem here as long as we talk about proper penalty. Not allowed to forge for the next 1440 blocks seems fair.

I want to know where I'm wrong and I want to hear CfB on both topics.

I think we should try to get off BTC and start trading Nxt for FIAT. If the price of BTC goes down, so goes the price of Nxt, although the whole MtGox-stor has nothing to do with Nxt.

How i can make a self-signed certificate? Some guide step to step?

If you account is unlocked, your forging! 

What are you talking about? Nodes to secure the network OR accounts that are forging. 2 different things

Am I forging right? I bought a BTC worth of NXT a few days ago, so I have around 11.5k. All I have to do is leave on my NXT client (NRS 0.7.6) and forging will happen by itself? The past few pages have been talking about how to change up forging to be more profitable... but my question is, how do I check on the progress of my forging?

Thanks! And happy NXTing!

Power forged for account and node maximum  100000 Nxt

Accounts with more than 100000 Nxt if they want to forge gradually will be divided into fractions Nxt 100000

accounts with less than 100000 Nxt will share their rights fees in pools. If bob account forge his fees will go into the pool.
Bob would receive a fraction fees as a function of the nxt he had.

The network in the worst case would reach 10 000 nodes

1000000000/100000 = 10000 Nodes

Translated into numbers

if a block has 256 transactions
and 1440 blocks are generated each day

a pool with 100000 nxt generated 52.6 blocks per year
if a Nxt equals 1 Dollar
Blocks 52.6 x 256 = 13,455 dollar per year


in the worst case nearly every week 256 dollar received a pool (grouping of accounts) with 100000 nxt

Bob would receive a fraction fees as a function of the nxt he had in the pool.

if for example the pool is formed by 256 equal  accounts each account will receive 1 dollar per week

Do not forget that you have also mantein your PC if you usually use for other things.

The 256 dollars are to maintain only your actives nodes per week

chances of forging only depends on the nxt you have

This solution at least provoke everyone who wants to forge receive fees every 2-3 days maximum one week.

This at least solves that small accounts are equally motivated to forge that big.

my thoughts are wrong?
