Subject: *.novaco.in RapidSSL Wildcard Order: 1......2 Complete

Dear A...,

Congratulations! RapidSSL has approved your request for a RapidSSL Wildcard certificate. Your certificate is included at the end of this email.

Today we are planning to move to https protocol on domain.

[Balthazar]

Well... Now we have registered a company and ordered a code signing certificate. So, the future windows builds will be signed.

[Balthazar]

Client-side address generator is available:


It was worked from bitaddress.org, non-opensource licensed parts were removed so paper wallet feature is unavailable yet.

If you wish to test this then you can download code from my repository:

https://github.com/CryptoManiac/bitaddress.org

or use this page

Just a little new competition.
The one who finds the first PoS block height 100 000 or more will receive a small bonus.

If you wish to support a winner, donations are accepted here:

Currently we have 34.84 NVC in this wallet.

Notice

On domain novaco.in held unscheduled work on updating the OS

Estimated time: 4 hours ...

Code Sign Sertificate for Novacoin wallet obtained...

first signed builds coming soon...

[Balthazar]

We've finally got Authenticode certificate. Current win32 builds of 0.4.4.7 were replaced with signed executables.

It seems that novacoin p2pool works incorrectly with asic devices, seems as roll-n-time problem. An appropriate fix is under development.

[Balthazar]

NovaCoin 0.4.4.7b5 update

Changes list:

• QT: dumpwallet & importwallet from the menu;
• QT: locking, unlocking & unlocking for mining from the menu;
• QT: Display input weight in the coin control table;
• QT: Proof-of-Stake miner status notifications in the GUI;
• Core: New fees policy. Introduce 0.001 coin per 1kb traffic cost, allow free transactions below 1kb. Becomes active since 20 July 2014;
• Core: Updated transactions verification protocol, allow timestamp drift for coinbase transaction to resolve p2pool mining issues. Becomes active since 20 August 2014.

ARMv6 gnueabihf build is coming soon.

Notable issues:

If you are getting "Blockchain redownload required approaching or past v.0.4.4.7b6 upgrade deadline." message then you have to remove your blockchain database files and resyncronize with the network again. You need to go to data directory and remove everything except wallet.dat file.

So `novacoind getrawtransaction 7473c894134d83bf4a0a5207310520c12edb9bf69411e27b672d77a847d553a0 1` results in:
error: {"code":-5,"message":"No information available about transaction"}

There was some mention of nested child blocks but I'm afraid I don't understand what happened here that made this coinbase transaction inaccessible to getrawtransaction.  Does anyone have a solution for this error?

[CoinHeavy]

I was doing a progressive scan through the blockchain when I encountered this issue. It appears that all POS transactions have two sub transactions, one of which is unparsable (by novacoind) and occupies the 0th index in the transaction list for the block. The second PoS sub transaction contains the actual generation.

If there are no inputs or outputs to these marker transactions, what purpose do they serve? Why two transactions for PoS and not one?

So `novacoind getrawtransaction 7473c894134d83bf4a0a5207310520c12edb9bf69411e27b672d77a847d553a0 1` results in:
error: {"code":-5,"message":"No information available about transaction"}

It's a normal behavior for 0.4.4.7 clients family. Coinbase transactions of proof-of-stake blocks are ignored by block connection procedures. That's why these transactions are unavailable through RPC.

If there are no inputs or outputs to these marker transactions, what purpose do they serve?

Empty coinbase transaction initially was used as a marker of proof-of-stake block. It's not used anymore but wasn't removed in order to keep a formal compatibility of block schema. Maybe it will be removed in the future versions.

Proof-of-Stake transaction is marked using empty output.

It could contain any amount of outputs, but the first output must be empty and the public key of second output destination must be matched with destination of the first input. I.e. this transaction can look as something like this:

Address -> |         | -> Empty output
           |         | -> Address
           |         |

or

Address -> |         | -> Empty output
           |         | -> Address
           |         | -> Address

Address -> |         | -> Empty output
Address -> |         |
Address -> |         |

or even

Address -> |         | -> Empty output
Address -> |         | -> Address
Address -> |         | -> Address

Hello.
nvc.khore.org as been updated. A small patch was needed to stratum-mining due to change in "getblocktemplate" default action.
Will push it to github later.

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

This executable scans registry and searching for the wallets. Seems as trojan horse to me, please don't download anything.

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:
