gottA LOVE I JUST FOUND AN OLD WALLET W 2+ YRS COIN AGE ..... WISH I HAD KEPT MORE

[Dek52]

Been mining and trading Novacoins since the beginning. Most likely I am the #1 block finder on the Nova coin network with over 1700 blocks to my name. Something strange on the Btc-e exchange happen Friday 8/7 and I am wondering why coin holder did not benefit from it. The Btc-e exchange registered that appox. 20 million USD moved thru NVC and the trade volume was more then 100,000 plus coins at any givin moment.  My question is why did this not reflect in the value of the coin.  The reason why I am asking, if there was a 20 million USD movement thru NVC, it should have reflected in NVC value, each coin should have been valued at appox. 20 USD each. I'm just wondering if anyone else noticed this and what is their take on it.

It's a mystery. My guess is that it's fake volume caused by a bot trading with itself, but I could be wrong!

Edit: Looks like I guessed right:

Dear BTC-e Customers!

We’re happy to announce that BTC-e exchange is celebrating its 4th anniversary. Congratulations from BTC-e Team!

To celebrate, we’ll reduce the trading fees for all pairs to 0% on Aug. 7th 2015 from 00:00 till 23:59.

Hi guys

Few weeks ago I have published a simple client implementation of Stratum protocol.

https://github.com/CryptoManiac/StratumLibrary

Currently working on pure C# implementation of basic NVC protocol features.

https://github.com/CryptoManiac/NovacoinLibrary

While libraries are far from being complete, this code already may be useful for block or transaction parsing, generation of addresses etc. The goal is to implement a minimum which is required to create our own implementation of Electrum client.

On bottom of novaco.in domain pages:

I find a bug/typo or I have a suggestion

and new menu item Issues also...

[mullick]

Hello everyone,

I opened up the following issue on github. Havent seen this one before with another coin.

https://github.com/novacoin-project/novacoin/issues/228

Repair wallet shows all is well

Code:

novacoind repairwallet
{
    "wallet check passed" : true
}

Rescan also had no effect

Here is the unspendable input in question

Code:

novacoind listunspent
[
    {
        "txid" : "93ef6167d4f1246f05ee0e65f92fac80b25ec2f8025d538d8a5d80351ff1f34f",
        "vout" : 0,
        "address" : "4SCy6zmrWMtUhMa9qbseo7RCTCo4c5CeFd",
        "scriptPubKey" : "76a91489247075a87a815820de81d387735c831a8605c488ac",
        "amount" : 0.09899900,
        "confirmations" : 8,
        "spendable" : true
    }
]

It seems I just cant spend the input in its entirety

EDIT:

Creating a raw transaction also fails

novacoind createrawtransaction '[{"txid":"93ef6167d4f1246f05ee0e65f92fac80b25ec2f8025d538d8a5d80351ff1f34f","vout":0}]' '{"edited out for privacy":0.979}'

novacoind sendrawtransaction "edited out the signed rawtransaction"

error: {"code":-22,"message":"TX rejected"}

*edit #2*

Stupid typo. Raw transaction sent correctly

Still an issue with the getinfo calculation and not being able to spend it using sendtoaddress

[Balthazar]

There are many reasons possible, one of those is fee calculation. The debug.log would be very helpful.

Fee calculation makes sense for not being able to send it. But I have never seen a daemon round the balance for getinfo before

Hi guys

Few weeks ago I have published a simple client implementation of Stratum protocol.

https://github.com/CryptoManiac/StratumLibrary

Currently working on pure C# implementation of basic NVC protocol features.

https://github.com/CryptoManiac/NovacoinLibrary

While libraries are far from being complete, this code already may be useful for block or transaction parsing, generation of addresses etc. The goal is to implement a minimum which is required to create our own implementation of Electrum client.

Stack machine has been implemented. It's fully functional and compatible with current NVC client. This means that you can use it to run any scripts which are able to run on standard script machine.

Example of input validation:

Code:

// Script validation test

CTransaction txTo = new CTransaction(Interop.HexToList("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"));

PoW difficulty = 3600
PoW Reward = 6.4 NVC

thanks Litecoin Halfing!
Interesting to see that so many miners are switching over to Novacoin instead of turning off their miners.

But Litecoin difficulty will go down, so this will be just temporary. But it will stabilize on a higher level than before the Litecoin halfing.

=> More security for Novacoin, less inflation 

[Balthazar]

Bitcoin is currently very dependent on chinese miners, for example. That would be a good idea to perform some research on the distribution of hashrate, because many people would like to know who's making weather in our network.

This function provides you an ability to get actual timestamp from some specific NTP server, or from a random server if none has been specified. Such functionality may be useful for applications which are working with novacoind over RPC protocol.
