One counter-evidence: Satoshi seemed to be a Windows programmer, rather than a Linux programmer(which I don't think is an identity he needs to hide, after all there too many out there fit this stereotype)
Good point

It's not like this?

Yep, I don't think OP search for long

tl;dr:
Schmidt didn't give a shit
Assange was high: "it is not going to decay like apples or steaks."

Even simpler!
Thanks!
4145  Bitcoin / Development & Technical Discussion / Best chain when same length on: May 27, 2013, 06:52:59 PM
How is chosen the best chain between two chains with the same length?
First timestamp? Lower hash?

1.
You need to add that function:
Code:
def DecodeBase58Check(sec):
vchRet = b58decode(sec, None)
secret = vchRet[0:-4]
csum = vchRet[-4:]
hash = Hash(secret)
cs32 = hash[0:4]
if cs32 != csum:
return None
else:
return secret

pvk1=DecodeBase58Check("5KWLD8VF29WR36qR2YM3wWLDuePHJAP4YKgCMcfvNN7TTxSFgFx")

2.
Code:
pubkey = EC_KEY(pvk1, bool(compressed key or not?)).pubkey  #this is an object
pbk = pubkey.ser()   #the serialization itself: 04+x+y or 02+x or 03+x

Can the developer please complement on this? If you say it's a 21 billion cap, then why does the source code have no limit?

21 Billion is the cap on a WALLET, when me and the other people were discussing it on the other thread we were mistaken.
You can find out how many coins are out by looking at the Block explorer Smiley
A 'wallet' has no meaning in the protocol
Address? Client?
4149  Bitcoin / Development & Technical Discussion / Re: Again, a block with 0 transactions is accepted on: May 27, 2013, 03:44:01 PM
Actually that won't change anything, the miner can create tons of dummy transactions
4150  Bitcoin / Development & Technical Discussion / Valid transaction on: May 27, 2013, 12:23:09 PM
The wiki says that "a transaction is valid if nothing in the combined script triggers failure and the top stack item is true (non-zero)"
But "x==OP_TRUE" != "x!=OP_0"
So which one is correct?
4151  Local / Discussions générales et utilisation du Bitcoin / Re: Qu'arrive t-il si les bitcoins sont perdus ? on: May 27, 2013, 12:09:04 PM
Il existe un site qui permet d'imprimer des billets papiers : https://www.bitaddress.org (onglet paper wallet).

Il suffit d'envoyer vos bitcoins à l'adresse indiquée sur le billet, puis de le placer en lieu sûr.
Et pour ré-utiliser les bitcoins, il faudra utiliser la clé privée inscrite sur le billet en utilisant le logiciel bitcoin-qt ou bien le site blockchain.info.
Le mieux est de sauvegarder la page de bitaddress (fichier, enregistrer sous) et de la lancer sur un ordi non connecté à internet

Same happened for me
I never managed to get SDL working even for small tasks whereas SFML is a pleasure to use

I meant how do you do pubkey->address and privkey->address?

Seems legit

What you do seems ok, do you use the same 'compressedness' for both?
How do you calculate the addresses?
4157  Bitcoin / Development & Technical Discussion / Re: Pywallet: manage your wallets/addresses/keys/tx's on: May 27, 2013, 06:38:04 AM
That's not possible, and that's what I meant by "the way Bitcoin stores txs": the key is "tx"+hash(tax). So you can apply what you proposed only if you know the hash.

Hmm, wait, I just get it, yes we have the hashes because you use the file to store them... I don't know why I thought you were using 'all'
There's some hope for speed improvement then!

Can this work on jailbroken iOS?
Yes absolutely. I made it work on iOS 5.
Look if there's a Python port for your iOS. If so that should work.
4158  Alternate cryptocurrencies / Altcoin Discussion / Re: Value of testnet coins on: May 26, 2013, 07:10:06 PM
Sure you could just copy-paste bitcoin to start an alt-coin but I think there is a real security issue with alt-coins.
No. Copy-pasting is copy-pasting, no security issues are added. It just requires to fork the bitcoin github repo, change the genesis block/magic bytes and port, and apply every commit that are applied to the official bitcoin repo in the future. This way it's an EXACT copy of bitcoin.


That's not easier then just using the testnet that already exists.
But it IS easier than using testnetN-1 each time that core devs make testnetN


Oh Lord. WTF am I even reading.
You know what? Ok, great, go on, make testnet coins valuable and try to sell them.

4159  Bitcoin / Development & Technical Discussion / Re: Pywallet: manage your wallets/addresses/keys/tx's on: May 26, 2013, 07:01:41 PM
I made a small improvement
I'm not really sure it would change a lot though. I don't think it might make it faster than now, because of the way Bitcoin stores the txs
4160  Alternate cryptocurrencies / Altcoin Discussion / Re: Devcoin on: May 26, 2013, 06:14:42 PM
I just noticed that user pages are apparently editable by any user, this is not good. It's only a matter of time until someone goes around replacing payment addresses and article links and some will notice too late, if ever. Manual control will only work so long, there needs to be a lock on user pages to make them editable by just the individual users themselves.

I believe Unthinkingbit keeps backups, so if it ever happens he can just upload it back to its regular self.
I'm not sure he would check every page
Someone can make a bot though (I can if nobody has the time)
