And again...

• Core: Proof-of-Stake miner optimizations and cleanup;
• Core: Remove BDB support;
• Core: Automatically remove old transactions index database if that's necessary, no runaway exceptions anymore.

P.S. Mac OS X build was replaced too.

how fast so crypto

// I've just thought about selling nootropic medicines for some NVC... I have 1kg of Piracetam and I think that it's really too much  

Wow such balance many input

Proof-of-Work and Proof-of-Stake mining using more than 1 million coins and almost 20k transactions. Stake miner eats one CPU core but there is absolutely no performance issues.  

It actually doesn't matter, but we'll try to decrease CPU usage in the future.

I think that it's all about balance.   Traders and miners are parts of self-regulated system.

For the reward lower than 1.00 we need a difficulty higher than 240000000. I doubt that it's possible in 2014.



Anyway, we can change PoW reward function to make a reward drop slower or faster, if this would be requested by majority of users... But this would require a voting like it happened with PoS reward function before.

No, your coin-days are still available. You need to wait until block will be generated.

I am curious of opinions from the community about mining Novacoin VS. pointing my miners at the currently most profitable coin and then buying novacoins with the earnings.  Mining on Novacoin will be better for the network, but buying it on BTC-e with earnings from one of these multi-pools will get more NVC in the end, and in theory will raise it's mining profitability attracting more hash power.  Which do you think would be most beneficial to the coin?

Another thing that I would like to comment on and is somewhat related is the ramifications that scrypt FPGAs will have on the NVC block reward  

When the more powerful ASICs really started hitting the pools, PPC hash rate would spike every time BTC difficulty adjusted which in turn pushed the block reward down.  It seems many miners took an interest in PPC after these profitability spikes happened.  This appears to have benefitted PPC greatly regarding the market price.  Many thought PPC would be super plentiful, because people didn't imagine how much the block reward would change.

I think it is safe to say that there are currently scrypt FPGAs in the wild or at least a dump truck full of new GPUs mining scrypt from profits of the past months.  As these FPGAs start to ship out, the NVC difficulty will more than likely increase which will make the block reward smaller.  Anyone else think we will see < 1 NVC PoW block reward in 2014?  Talk about a rare coin!

Novacoin, it's like gold bullion bars to Bitcoin's 1oz round

i started the PoS on nvc istarted with small amount after around 50 days i received a an orphan stake and then i got a message that the blockchain is forked and need to update

i updated 4 days ago and still nothing has been staked

so did i waste 50 days?

Experimental builds are updated again.  [AMD64  | i686 | src]

Changes list:

• Core: New proof-of-stake miner implementation. Performance issues resolved, almost 100x faster with massive inputs amount;
• Qt: Coinbase/coinstake transaction records appearance unification;
• Lib: update to Berkeley DB 6.0.20.

It was decided to update some libraries, which are used for Windows builds


New builds are backward-compatible, but wallet.dat becomes unreadable for old builds once it was opened by new client.

Testing builds for compatibility checking: [AMD64  | i686]

It seems that some stupid scums are trying to promote their "point of view" in the WoT database.

There's no forms, there is no registration. How is this supposed to be a spamtrap? I didn't seen something so stupid ever.

Hello,

Come make us a visit!! Still 0% fee.

Stratum, VARDIFF tuned to allow small miners, MPOS and once we soon fast payments.

We need candidates for the current prevhash only... It's not necessary to store old candidates, we are free to drop all of them immediately if prevhash was changed (i.e. new block was found). It would require something like 10 megabytes of additional RAM, I guess.

You are right, not everybody need such functionality. But for some purposes (e.g. payments for fastfood) it's almost equal to immediate confirmations, so I presume this would be useful.

Both of these will require resource allocation at each (?) wallet. Do you have estimation of how much that could be?
It might be reasonable to only let some of the nodes do this kind of work. Presumably, whoever handles payments will run more or less a dedicated node with enough resources.

Just a little piece of info...

As far we know, some payment processors and users accepts 0/unconfirmed transactions. But this solution is not secure, because it's possible to create two transactions with the same inputs, but different outputs.

http://eprint.iacr.org/2012/248.pdf

Attacker is able to send a first transaction directly to victim, and then broadcast a second transaction over the network. This couldn't be prevented using the proof-of-work design, but it's possible to fight with such manipulations through using an extension for our proof-of-stake system, and we even don't need a chain fork to implement this.

Block candidates submission concept

This would allow user to check that his unconfirmed transaction is accepted into the specific stakeholder's memory pool.

It doesn't provide guarantee of fast confirmation, but it makes a double spending of 0/unconfirmed transactions much harder. It will be required to use some stake in order to perform such type of double spend attack.

How this could work?

1. We have a blockchain, so we can get a full list of stakeholders with suitable inputs weight (i.e. users who are able to generate proof-of-stake blocks and allowed to submit the block candidates);
2. We can check a signature of received block candidate;
3. As a result, we have a proof that specific stakeholder has a declared list of transactions in the own memory pool. Or seen those transactions, at least.

How is this supposed to work?

Stakeholder will be allowed to send proof-of-stake candidates over the network. Candidate is required to satisfy a difficulty, which would be set separately from the main chain. And then there are few different approaches could be used to handle this.

• Block candidates map;
• Temporary pseuso-chain for block candidates;

Maybe we'll think about implementing this in the future version...

You can continue using 0.4.4.5 like btc-e does, but it's better to apply 0.4.4.6 because it works much faster and ignores the current notification.

P.S. "Much faster" is up to 20x speed up on a slow CPUs like Intel Atom or ARMv6.

Hi guys.

This message is just a notification which was used to send users read the FAQ in this thread.

Check your client version, if you are running 0.4.4.5 or higher then it's safe to ignore this message.

my cleint says:
some clients were affected by chai nfork issue. and send me here but i dont see what shoild i do?

Hey Balthazar, just to confirm, I should be all fine with the blockchain issue with version v0.4.4.5-2-gde717f9-beta right?   Thanks.  I updated to the latest version but it crashed with an error so I went back to this one.

a new permanent node running 0.4.4.6 at 193.68.21.44
