Hello
Found utility for calculating PoS mining, can anyone would be interested. Like considers correct.

Hello.
Looks like you are sending an already spent input. You need to re-download the blockchain.
This can happen if you use the same wallet in several instances of novacoin daemon.

Your coins were already spent here:

This wallet has never been used in any other locations.

Why should redownloading the blockchain work vs. a rescan?

Your client is unable to see this transaction in the local copy of blockchain, but it seems that transaction has been sent and confirmed properly:

https://explorer.novaco.in/tx/2849cfe9e487fb45f88fc36a61c1d42d2be1bb8d58a99df59f39dbead78e47b7

You can find it in block #106134.

Possible reasons are corrupt database or obsolete version.

P.S. Future builds will be able to save tx mempool data to hdd, this will be helpful to prevent the most part of such issues.

So it's returning an error, but the coins are actually sending?  That's even worse.

Creation of transaction & sending transaction are separate operations. The daemon couldn't send transaction for some reason, but then it was re-broadcasted using a local copy got from the wallet.dat. It's a regular behavior for any satoshi-based client, especially when a local copy of blockchain isn't syncronized properly.

If you wish to prevent re-broadcasting then you can use RAW transactions API to perform your payments. RAW transactions are saved only if those transactions are accepted and valid.

You need these functions:

  • listunspent - returns a list of available inputs;
  • createrawtransaction '[{"txid":"deadbeef...", vout:0}, ...]' '{"address1":10.01, "address2": 1.22, ...}'- create raw transaction. Returns transaction data on success. Please note that difference between outputs and input sums will be considered as transaction fee;
  • signrawtransaction <txdata> - append signatures to raw transaction, returns object which contains a signed transaction code and signing status;
  • sendrawtransaction <txdata> - sends transaction over the network, returns true on success or false otherwise.

So after the transaction was rebroadcasted wouldn't it show up as confirmed?  Why is it still showing conflicted?

Hi flound1129 Smiley

So after the transaction was rebroadcasted wouldn't it show up as confirmed?
It will show this transaction as confirmed once block with transaction will be accepted. Your client is synchronized with the rest of the network properly, or not?

Why is it still showing conflicted?
"Conflicted" status means that transaction exists in the wallet, but doesn't exist neither in the memory pool nor blockchain. Memory pool is currently exists only as a memory structure, it doesn't saved to HDD yet. So, any unconfirmed transaction could be shown as "conflicted" after restart unless your client gets a copy of this transaction into memory pool. This problem will be resolved in the next release, through saving a copy of memory pool to HDD.

       "account" : "",
        "address" : "4PNf73X2L9iUm3cE6tvFq919XrHeiEmPtQ",
        "category" : "conflicted",
        "amount" : -0.18378200,
        "fee" : -0.01000000,
        "confirmations" : -1,
        "txid" : "6d67a895afe4d077ccf62351c2263295c2fe312ed80e6fdefe259beff64c97e4",
        "metahash" : "8ae7e84de3445781bc15194f09813f3c0aae57fb7ee034bf119a1681ae848aa7",
        "walletconflicts" : [
            "cc5699d0dd84468665d693751646bf497b921b68a78163691947c5bb09d51c36"
        ],  
        "time" : 1404720093,
        "timereceived" : 1404720093
https://explorer.novaco.in/tx/cc5699d0dd84468665d693751646bf497b921b68a78163691947c5bb09d51c36

cc5699d0dd84468665d6 transaction exists in the main chain, it seems that your transaction is trying to use input which was spent by this transaction.

WTF is going on?  am I on a buggy version?  What version should I be on?
Actually, there are nothing going on yet, so this situation seems pretty surprising for me too.  Current version is 0.4.4.7 bugfix5, this release contains some protocol changes, but these changes will be activated only since 20 Jul. Stake entropy calculation update was added by 0.4.4.6u3, but this update has become active more than a month ago. So, now there is nothing new in the network yet. Roll Eyes

Try to apply 0.4.4.7b5 update, maybe it will resolve this situation.

What is the current annual stake rate for NVC?  I see in main.h that it starts at 100%, but it is my understanding that with the rise in difficulty that the reduction of stake rate has kicked into gear.

Keep up the good work here. We all know that NVC created a whole bunch of fun coins.

I'm still getting the conflicted transactions with v0.4.4.7-nvc-bugfix5-beta afer redownloading the blockchain.

Also, now the entire balance disappears and doesn't come back unless I do a -salvagewallet or a -rescan.

Attention please!

There is a critical issue with block chain syncronization in 0.4.4.7 versions of novacoin client. If you are using 0.4.4.7 then downgrade to 0.4.4.6 update 3 or update2 is strictly recommended.

Binaries for linux armv6 and win32/win64 are available at sourceforge.

Unaffected source could be cloned from legacy repository:

git clone -b legacy https://github.com/novacoin-project/novacoin

Issue is currently under investigation.

Valid chain is currently consists of 107621 blocks, block #107620 is 000000000070ac2d51c8b288dcb18adca11bd4571a8e8c7e27fad3994980c7fd.

Master branch was recreated as a copy of 'legacy', 'current' was renamed to 'unstable'.

Update of 0.4.4.6 branch is scheduled tomorrow, it will include recent interface and protocol changes from 0.4.4.7.

Is this related at all to my issue?  Sends seem to be working normally again on 0.4.4.6.
