Another important piece of information that's missing is the current annual interest rate. I don't want to calculate that by hand all the time.  Roll Eyes

You should merge in this LTC change ASAP, apparently it fixes a memory exhaustion attack.

We usually able to fix the vulnerabilities faster than another altcoin projects.

https://bitcointalk.org/index.php?topic=143221.msg2532345#msg2532345

It's already fixed 6 days ago in 0.4.3.

Any idea what's the active user base of NVC is like? I'm asking 'cause I run ALTcointip bot and NVC is the only coin that's never been used since very beginning. Even /r/novacoin is dead.

You can see here how many times the clients have been downloaded:

http://sourceforge.net/projects/novacoin/files/

That's probably the best estimate about how many users there are.

Novacoin is the perfect coin for hoarders because it pays interest. I wouldn't dream of tipping novacoins just like I wouldn't tip gold coins.  Grin

Unfortunately, we can't see statistics for removed files (old releases). Roll Eyes

Currently the most part of users are investors, miners and some merchants owned by enthusiasts. Because there are not so many coins generated yet. But this will change when the mined volume will grow enough to allow higher capitalization.

Have you checked that page? I only see 300 downloads on it.

What do you think the real number is? NVC is the most mysterious out of all the coins... it's high value, it's stability, it's general lack of interest on here. Weird.

I think that we can estimate it using connections amount.

P2Pool currently works well, that's true. But there is a plan to restart p2pool shares chain after 20 Sep 2013.

New NVC protocol changes will be activated since this date, allowing us to remove ECDSA signatures for PoW blocks and 0.01 coin lower bound for coinbase outputs. So, P2Pool diff with upstream will become significantly smaller than diff of current P2Pool implementation. Also it will provide an opportunity to run public nodes without current limitations.

can anybody explain the interest calculation more exactly? maybe with an example?

i'm not able to calculate with a number like: 0x00000ffff0000000000000000000000000000000000000000000000000000000

Hi all. I asked my friends to publish 0.4.1 and 0.4.1 builds while I'm at hospital.

I'll publish the full changelog later, important changes are listed below.

  • Dynamic PoS interest. Now it's a function of PoS difficulty, nRewardCoinYear = 1 / (posdiff ^ 1/6). It can have values from 100% to 1%;
  • Checkpoints ignore option added, disabled by default;
  • Bug fix for coinstake transactions display in QT client;
  • Bug fix for AvailableCoins function, prevents immature coins usage;
  • Mac OS X compatibility issues resolved, from now we publishing official Mac OS X 64 bit builds also;
  • New genesis block for testnet.

Update should be performed before 20 June 2013.

So the expected reward will go down to 1.83% a year based on 0.025 PoS difficulty?
Minimal PoS difficulty is hard coded to 0.001. So, at 0.025 PoS difficulty you will get 1 / (0.025/0.001) ^ 1/6 = 0.59 coins per coin-year, i.e. 59% year interest.

ah, thx. so the current interest is: 1 / (0.04141117/0.001) ^ 1/6 = 53.76%

53% interest? Isn't that crazy high?

Yes, it's high at the moment but I think it will go down fairly quickly as the difficulty rises.

It depends on the number of blocks that are found by proof-of-stake. Read the PPCoin paper for the details:

http://www.ppcoin.org/static/ppcoin-paper.pdf

For the differences between PPCoin and Novacoin see the FAQ:

Not really.. if the difficulty shot up from 0.04 all the way to say 40 then the interest rate would still be:

1 / (40/0.001) ^ 1/6 = 17.09%

It depends on what a reasonable range for d is.. but the 1/6 power really keeps the changes slow.
