The higher the fees, the higher the chance it get's included in a block faster. In the far distant future, when and IF bitcoin succeeds, you'd be paying like 0.00000000000000000000001 fee. Likely even less, as this is per transaction, and by then the value of such a small coin will be very very high.

It's possible to compile Bitcoin-Qt as well, done it already. Depending on your toolchain(GCC 4.7+), you may need to compile the Qt libraries from source, only takes about an hour or so. Then the rest is easy.

Thanks for your input spudy12.

I've updated the mail functions so hopefully it works now. I also changed the description for the gold CFD.


Hi , i find 2 Xpath Injection

I've not received a PM from you. In general I would be really surprised if you find a vulnerability in this area.
Even if you found a bug, it is necessary to report it privately, if you want a reward. (and publish no details before warning me (this should be obvious))

Don't get me wrong, but such posts can destroy our image of a secure trading platform. You should remove it.

best regards.
Well if there's a bug, a security hole then obviously it's not really secure. But don't misinterpret my post. You shouldn't hide if you have security holes, but accept it and fix them Wink.

I don't suppose you've read the SCRYPT-README that I spent ages documenting.
Well I'll be damned, you actually came into this section?

To my experience, it takes a random amount of time for the withdrawal to be executed. I had a withdrawal more than a week before you, and I received the confirmation (saying the transfer is made) before the 7th and still haven't received the money. So I guess you are out of luck until the issues are totally cleared.

ETA: So you should be worried. Please post here if you get any information out of this service.

You do realize bitcoin24 has some problems with authority right now, don't you? Locked bank accounts and whatnot. I wouldn't be surprised if the owner just poofs and disappears.

I'd advise against registering on that phpBB forum, it's outdated based on the skin, which has not been used for a few years(since 2007-2008). And phpBB is easily hacked and still used md5 back then.

Take my information with a grain of salt, but if it's old, it's insecure.

I expected at least one alt-coin developer to see this thread and respond, but I am feeling now that they won't do it purely so a new alt-coin does not replace theirs, even if we are newbs here.

The distance between Earth and Mars is probably around 100,000,000 million kilometers at worst times. Provided a Radio Signal travels at nearly or at the speed of light in vacuum, it will only take a few seconds to transmit data back and forth.

By 2140, we will have satellite checkpoints which will act as relays for internet and stuff. With a small delay of a few seconds, it won't be a problem to have Martians connected to the Earth internet.

Have you guys taken a look at this proposal:

https://bitcointalk.org/index.php?topic=176556.0

The proposal is for Litecoin, but since you guys have a new blockchain(s) in the works, someone might want to try their hand at implementing this as a new coin.
As we are newbies, you can't possible expect us to do something like that now, do you?
2393  Alternate cryptocurrencies / Altcoin Discussion / Re: Terracoin is ALLIIIIIVEEEE on: April 14, 2013, 07:42:35 PM
hmmm confused? price doubled but its now 4 times less profitable to mine trc? did difficulty go up?
If you look at it in terms of TRC->BTC. If TRC is to be used as currency, you shouldn't look at it's price as per BTC.

However, this still doesn't explain line 7 of this file... so I am still missing something.
The hunt continues....
 
https://github.com/freicoin/freicoin/blob/master/share/find_genesis_block.py
Of course it does, that script basically takes an ALREADY CREATED merkle root, i.e the one you claim is output in debug.log.

Personally, I would like to write a C implementation where you provide some input and a genesis block will be created for you.

So if I understand correctly...  (more likely it's more complex... maybe not).

The genesis block is created.
Merkle root is created and output in the debug.log
find_genesis is run to get the Time Stamp, Nonce and Hash
This is all put back into the code (With Merkle value) and compiled
We are ready to mine.

I think it's basically this. This is the code from Bitcoin for creating the genesis block's coinbase.

Code:
        const char* pszTimestamp = "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks";
        CTransaction txNew;
        txNew.vin.resize(1);
        txNew.vout.resize(1);
        txNew.vin[0].scriptSig = CScript() << 486604799 << CBigNum(4) << vector<unsigned char>((const unsigned char*)pszTimestamp, (const unsigned char*)pszTimestamp + strlen(pszTimestamp));
        txNew.vout[0].nValue = 50 * COIN;
        txNew.vout[0].scriptPubKey = CScript() << ParseHex("04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f") << OP_CHECKSIG;

Which outputs this merkle 4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b(though not sure if it needs to big or little endian).

Then

Got some info from the devs of Bitcoin. Apparently this whole ordeal with Serialization is so that the data from this code

Code:
        const char* pszTimestamp = "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks";
        CTransaction txNew;
        txNew.vin.resize(1);
        txNew.vout.resize(1);
        txNew.vin[0].scriptSig = CScript() << 486604799 << CBigNum(4) << vector<unsigned char>((const unsigned char*)pszTimestamp, (const unsigned char*)pszTimestamp + strlen(pszTimestamp));
        txNew.vout[0].nValue = 50 * COIN;
        txNew.vout[0].scriptPubKey = CScript() << ParseHex("04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef38c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f") << OP_CHECKSIG;

is converted to bytes without caring what datatype they are from.

More like till an alt-coin dev sees the thread.
2399  Alternate cryptocurrencies / Altcoin Discussion / Re: How do you create an altcoin? on: April 14, 2013, 12:19:19 AM
If Sunny King can help us, it'd be nice. But I guess the reason the genesis block creation information is not found easily is because every noob(me included) on the block will have an alt-currency out by the end of the day.

It's open source... it may be obscure... but that doesn't mean people don't have a right to know how to do it.
By the end of this thread hopefully we'll all know how it works!   Wink
Yeah, but we likely won't understand the process itself.

But then how did altcoin authors create theirs?  Undecided
They've learned C++ and have no issue with the C++ semantics? Understand Cryptography more than we do?
