There is no such thing as a 0 transaction block.  Every block has at least 1 transaction in it.

Awesome observation  Shocked Please, make a gift of two or three more like this for my birthday  Grin

Requiring additional transactions in a block is a useless requirement that won't accomplish anything.

So you will accept a block with only 2 transactions?  Fine, miner creates a second transaction paying bitcoins from one address in his own wallet to another address in his own wallet.  Problem solved?


See: https://bitcointalk.org/index.php?topic=212146.msg2277187#msg2277187

That is an example of fair policy I'd take if I rule a pool.

Is the zero transaction block not an expression of market forces? I mean, if I want to charge high fees, I can artificially limit transactions by mining lots of blank blocks.

Even if not hardcoded, the rest of the network should reject such blocks. They are working hard with own and other's transactions. Nobody forces me to accept a block that is not including the transactions I want. So, block rejected and wait for a fair one.

This should be a real market, I think.
63  Bitcoin / Development & Technical Discussion / Re: Again, a block with 0 transactions is accepted on: May 27, 2013, 03:53:32 PM
Actually that won't change anything, the miner can create tons of dummy transactions

It's necessary, but perhaps not enough.
64  Bitcoin / Development & Technical Discussion / Re: Again, a block with 0 transactions is accepted on: May 27, 2013, 03:41:36 PM
While this miner is not adding transactions in his block, there will be times where there will be no TXes to add in a block and I am talking about edge-cases where a block is found seconds after another. Will you also reject those?

Yes.

I repeat: bitcoin is about transactions; so, no transaction should mean automatic rejection.

Perhaps this must be hardcoded in incoming releases of the client.

6 minutes after the previous.

In this thread is discussed similar event IMHO, pools, miners and nodes in general should reject such blocks. Bitcoin is a transaction system. If there is no transaction, the game is over.

Direct proof of your signature btw


 Grin

Well, in fact I don't stand for specific improve. I think, miners / nodes can reject such blocks within the actual protocol rules.
67  Bitcoin / Development & Technical Discussion / Re: Block 237226 on: May 26, 2013, 05:28:57 PM
Why the other nodes accepted the block!? I think nodes/miners can have the power to reject such blocks that bother the whole system.

Bitcoin is about transactions. So, no transaction, no subsidy.

Me preocupa que la moda infantil esa de poner imágenes chorras en los hilos se traslade a los foros en español.

Que los yankis se comporten como críos, allá ellos. Pero aquí somos gente seria.

I still didn't receive payment (anonymous miner). How much more time should we wait?

Paid tonight. Transaction confirmed  Cool

Sorry, I was on my mobile phone
It's 30 + len(z) + 02 + len(r) + r + 02 + len(s) + s, z being what follows its size, ie 02+len(r)+r+02+len(s)+s

Wow, it make sense now.

Beware: r and s are unsigned, so if first byte of r is > 7f: r='\x00'+r

 Shocked I don't see the logic behind this null addition. Unsigned is unsigned, so you can occupy the highest bit without permission....

Same for s
r and s are 32 bytes numbers, so, as it can one additional byte because of above, you have size(r)=0x20 or 0x21

So, I guess 0x1F, 0x1E, 0x1D... are allowed.

Thanks a lot!  Cheesy

It was our experiment with zero commission fee, just several users was affected.
Sorry for delay, eventually you will receive your bitcoins, it may take some time.

Look for DER format

Well, I've found the following: http://bitcoin.stackexchange.com/questions/2376/ecdsa-r-s-encoding-as-a-signature

which gives an orientation of how this matter works.

Thanks!
73  Bitcoin / Development & Technical Discussion / Format of ECDSA signature on: May 24, 2013, 03:37:00 PM
The only information about how bitcoin handles ECDSA-signatures, I've found here: https://en.bitcoin.it/wiki/ECDSA

If your read the link, It is said that Signatures are are either 73, 72, or 71 bytes long, But it does not make sense: signatures are pair of numbers (r,s), each of 32 bytes; so, 64 byte total. Plus an eventual id. prefix, 65 bytes maximum. If you want to add extra CRC-like stuff, then 65+4=69 bytes (and length fixed, because all leading '0's in the binary chain of (r,s) should be counted up).

So where the numbres "73,72,71" come from!?

TIA

Nova kriptomonero estis lanĉita: Worldcoin - WDC.

Plia rubomono... pardonu min, sed mi estas ege skeptika rilate al tiom multaj ĉifromonoj kiuj nur alportas bruon.

Kaj ĝi havas iujn esperantan influon kiel vi povas vidi en ĝia dezajno: "LIBERAJ VIROJ MONERO".

La devizo ne sencas. Ĉu vi celas diri "mon(er)o por liberaj viroj"? Krome... ĉu tiu mono ne utilas por virinoj!? Eventuale, mi konjektas ke vi celas diri "mon(ero)o por liberaj HOMOJ".

ldminer, Shevek, favelle75,
This issue is known and we are fixing it right now. Anyway, your payment will be either done or you receive them back.
To ensure that your payment will be successfully done, please send your pool's account e-mail and transaction ID in PM.

OK, thanks for the feedback.

But I don't understand this "please send your pool's account e-mail". I'm mining anonymously; so, I guess I can confirm by sending my mining address.

Is there any problem with anonymous mining? 50BTC used to pay daily until April 27th, then they changed (without prior announcement) to weekly payments and paid every Saturday (May 4th and 11th). I was expecting a payment yesterday, but none arrived.  Huh

Same for me :-(

Si en windows vas a jugar... ¿para qué necesitas bitcoin-qt?

Cuando necesites hacer transacciones vuelves a Linux, arrancas bitcoin-qt, esperas (o no) a que se actualice la cadena y haces tu operación.
79  Bitcoin / Bitcoin Technical Support / Re: Hacked and stolen on: May 17, 2013, 01:44:20 PM
This man is right.

Until bitcoin can be used without risk by windows dummies, it should be declared a danger matter.

El mayor inconveniente real es que las LTC no valen una mierda.
