[ANNOUNCE] New alternate cryptocurrency - Geist Geld

RE: hidden recipient address:
... I'll update the wiki [with a simpler version of "hidden recipient address"]

I believe that your simpler version of "hidden recipient address" can be redeemed by anyone (most probably a miner) by rewriting the transaction which includes the revealed secret in order to credit themselves.
In short - it's insecure.

Where in the code does it prevent the addition of bignums with OP_ADD?

RE: where in the code:  script.cpp

Code:

static const size_t nMaxNumSize = 4;


CBigNum CastToBigNum(const valtype& vch)
{
    if (vch.size() > nMaxNumSize)
        throw runtime_error("CastToBigNum() : overflow");
    // Get rid of extra leading zeros                                                                                                                 
    return CBigNum(CBigNum(vch).getvch());
}

... and all of the arithmetic binary ops do a CastToBigNum()

nMaxNumSize = 4 means numbers added must be 32-bits or less.

RE: simpler version being redeemed by anybody by rewriting:  D'oh!  Right, definitely need a signature so the transaction can't be modified between being broadcast and being included in a block.  I'll remove it from the wiki page.

BTW, I am giving away the Geists I mined today (except for the bounty/laundry "fund" of course ) which is 1407 Geists.

Hurry to be the first to apply,   ^__^

Something must be awry... I have been successfully mining on my bitcoind and it says we are at 205 blocks. You'd have mined 201 blocks for those 1407 Geists... but I know that is not possible because of my own balance. When I started (about an hour ago) it was on block ~25. Am I on the wrong blockchain or what? Using the Linux compiled from GitHub and the bitcoin.conf in your recent "reboot" post.

Strange, you might be on some chain fork or something (I did, however, change the magic numbers so old geists wouldn't talk with new ones so dunno where could that fork come from  )

200 something blocks were pre-mined (No 200 is a checkpoint), from the top of my head 201 (hence 1407 Geists) but if I actually pre-mined 205 (they could have been caught while I was reaching for the guiminer icon, lol) then I'll add 28 to the "forum fund" lol

Try using the chunk of chain found in the "blockchain+conf" folder in git if oddity persists.

Lol, sure thing, I'll set aside about half for you and half for whomever else claims and posts adress oke ?

[foggyb]

I'll take some too! Will post my address in two minutes.

Are you able to prevent the previous exploits? Is there anything to keep someone from overpowering the network again? I understand why you rebooted the chain, but if it is just going to keep happening then what is the point?

The answer to this question is yes. A "51%" attacker is still capable of doing what a 51-er is supposed to be capable of doing (double-spends, and, if huge enough, rewrites), but should not be able to arbitrarily manipulate difficulty to his advantage without invalidating blocks.

Also, new adjustment limits make diff adjustment smoother, without random "spikes" that occasionally unnerved people in previous version, though the cost is somewhat less rapid response to large alterations in difficulty (don't worry, not as bad as namecoin a couple of minutes as opposed to tens of seconds)

Oky, standing by for addresses

Trying solo, i get a couple of accepts then straight to all rejects? anyone else?

If you just started its possble the first accepted ones were done before you had the whole block chain downloaded and thats why they were quicker because the difficulty was lower.

Still getting this error.

Downloaded the GeistGeld_new, changed user/pass for miner and can't connect to IRC channel (it seems?).
