3221  Bitcoin / Bitcoin Discussion / Re: Bitcoin XT has code which downloads your IP address to facilitate blacklisting on: August 27, 2015, 01:57:58 AM

Here's the part you missed:

The IP list thats included in the commit:
http://pastebin.com/F15aHDMJ

It doesn't need to be downloaded from tor project.
They are just all tor exit nodes! Roll Eyes
What do you think that they'll care about this?
They are public servers, they work as public servers!

XT isn't even going to give a shit about them until it receives a possible DoS attack.
And it isn't going to connect them, it will just put them under a low priority, to avoid getting too many connections from them (because the DoS attack)

Damn it! You don't really know what you are talking about, just repeating repeating ...

Are you kidding?

https://github.com/bitcoinxt/bitcoinxt/commit/73c9efe74c5cc8faea9c2b2c785a2f5b68aa4c23

The code has both a static list and a list that's downloaded when the node starts.

Quote from: VirosaGITS
portion of the bitcoin community is going to reverse their decision on a fork that allow the devs to upload an IP black list.
Do you know the difference betwean the words "uploading" and "downloading"?

Do you know that if you set a proxy then XT will not download any list from torproject.org ?
Do you know that you can just start the node with this flag -disableipprio flag XT will not download any list from torproject.org ?


And one more thing, do you know what does this code on Bitcoin Core?  
OMG all of them will know your IP! Shocked

Code:
        vSeeds.push_back(CDNSSeedData("bitcoin.sipa.be", "seed.bitcoin.sipa.be")); // Pieter Wuille
        vSeeds.push_back(CDNSSeedData("bluematt.me", "dnsseed.bluematt.me")); // Matt Corallo
        vSeeds.push_back(CDNSSeedData("dashjr.org", "dnsseed.bitcoin.dashjr.org")); // Luke Dashjr
        vSeeds.push_back(CDNSSeedData("bitcoinstats.com", "seed.bitcoinstats.com")); // Christian Decker
        vSeeds.push_back(CDNSSeedData("xf2.org", "bitseed.xf2.org")); // Jeff Garzik
        vSeeds.push_back(CDNSSeedData("bitcoin.jonasschnelli.ch", "seed.bitcoin.jonasschnelli.ch")); // Jonas Schnelli


You are just another parrot.

If we persist on doing that someone WILL take advantage of the free space. Now what happens if 8MB blocks get filled up way before the intended increase?
The connection of the common nodes aren't able to share easily this kind of blocks, so there will be orphan blocks, miners will lose money.
Do you know what happen when a miner lose money by doing something? Easy, he will stop doing it, because he wants more money.  Shocked  Roll Eyes
It is easy, a simple logic, but all of you are full of propaganda.

There isn't any fork that allow devs to upload any IP black list, you are just parrot that repeat the first word that you hear without know the meaning.

I can actually tell you right now  Grin Fees will be raised !
Yes, I'm sure about this.  Grin
And then you will hear users screaming around because they are paying up to 1$ or more (some thinks that it's ok to pay 20$) to get confirmations.
For some, the confirmation will arrive after hours or days.

What do you think that will happen after this? Do you think that users will continue to use Bitcoin or just one of the other 500 alternatives? (and there are some that are pointing to take the place of Bitcoin)

Less users = higher price?
I think NOT Wink

Some of you have no clue about all of this Roll Eyes (or are in bad faith, maybe you just own other coins ...)
3226  Bitcoin / Bitcoin Discussion / Re: Bitcoin XT has code which downloads your IP address to facilitate blacklisting on: August 27, 2015, 01:20:49 AM
The longest chain is what the majority of the network chooses.
If the majority of the network will be on XT or anything else that support BIP101 (or others), than it will be the chain, it will be "the Bitcoin".

We have to see what will happen when the 1MB limit will be reached ... I hope that this will happen soon.
3227  Bitcoin / Bitcoin Discussion / Re: #Blocksize Survey on: August 27, 2015, 12:14:17 AM
Just remember everyone, that everything is started because the limit of the actual block size.
So, if the community will make the wrong choice by still limiting too much the size, we will need to start again all of these mess to make another fork Roll Eyes

Since Lightning is open source Blockstream has no proprietary advantage over its development, its deployment or monetization. 
Have you ever heard about the network effect?  Roll Eyes
3229  Bitcoin / Bitcoin Discussion / Re: Bitcoin XT - Officially #REKT (also goes for BIP101 fraud) on: August 26, 2015, 08:05:46 PM
Can someone do me a favor and summarize the differences between the XT implementation and BIP 101? I think most are aware by now that nodes can run https://github.com/bitcoinxt/bitcoinxt/tree/only-bigblocks but since much of the discussion is about XT and not BIP 101, I think this would be very helpful. Thanks in advance.
Here you can see the patches:
https://bitcoinxt.software/patches.html

If you chose to run "only-bigblocks", your node will only have this patch:
Quote
Bigger blocks, by Gavin Andresen. This set of patches performs some small code refactorings, and implements support for switching to 8 megabyte blocks after January 2016 once 75%+ of mined blocks are voting for the change by setting flags in the block version field. Once supermajority has been reached, there is a grace period of two weeks before the rule change takes effect. After the switch the max block size limit smoothly increases, doubling every two years. The soft limit is set equal to the hard limit to avoid the need for miners to constantly reconfigure things.
3230  Bitcoin / Bitcoin Discussion / Re: #Blocksize Survey on: August 26, 2015, 07:47:39 PM
BIP100 is bad for the market, because it add unpredictability, by giving votes to the miners.
This will just push the market (services) and users to other networks.  Roll Eyes

If BIP100 is chosen, you can be sure that will we need another earlier fork to take away the vote from the miners, if we want to get the Bitcoin to survive the competitors.

So, you are another one that loves authority and hate the people can have a freedom of choice.
3232  Bitcoin / Bitcoin Discussion / Re: Bitcoin XT - Officially #REKT (also goes for BIP101 fraud) on: August 26, 2015, 07:13:38 PM
No. XT includes many other things other than BIP 101.
This doesn't.
https://github.com/bitcoinxt/bitcoinxt/tree/only-bigblocks

It is only BIP101.

Can you please go somewhere else posting offtopic?
It's clear that you don't understand the difference between this (and Warp Wallet) and the common brainwallet as it was brainwallet.org.
3236  Local / Guide (Italiano) / brainwallet.io / keybase.io/warp - Brainwallet usando Scrypt on: August 26, 2015, 02:16:51 PM
Riguardo ai brainwallet molti avranno già letto che ne viene spesso sconsigliato l'uso perchè insicuro.
Sono insicuri perchè il metodo per ricavare la chiave privata da una frase (attraverso SHA256) è facilmente attaccabile attraverso dictionary attack.
Cioè provando tante combinazioni di parole e frase conosciute.
I calcolatori di oggi (FPGA/ASIC) sono in grado di provare tantissime combinazioni in poco tempo, e inoltre comunque spesso e volentieri l'essere umano non è grado di scegliere delle combinazioni non comuni.

Questo vuol dire è veramente facile per un calcolatore trovare le frasi degli utenti in poco tempo e prendere i loro Bitcoin.

Viene quindi proposta una soluzione dove invece di SHA256, si fa uso di Scrypt (https://en.wikipedia.org/wiki/Scrypt)
Questa funzione richiede un uso intenso di molta memoria rispetto allo SHA256, e quindi rende molto più difficoltoso un attacco bruteforce.

Questi sono due proposte che fanno uso di questo metodo:

Sito: https://brainwallet.io
Codice: https://github.com/routman/brainwallet.io

Sito: https://keybase.io/warp
Codice: https://github.com/keybase/warpwallet

EDIT:
Fork di Warp che genera BIP39 mnemonic e BIP32 extended keys
https://github.com/Logicwax/PortalWallet

Entrambi non sono servizi "remoti", nel senso che le pagine possono essere salvate in locale, e il brainwallet generato offline.
Si può anche fare appunto scaricando direttamente il codice dal loro repository Github.

Oltre alla passphrase (la lista di parole), viene chiesto anche un/il salt ( https://it.wikipedia.org/wiki/Sale_(crittografia) )
Questo per rendere ancora più difficoltoso l'uso di un bruteforce casuale sulle parole, visto che servirebbe sapere con assoluta certezza anche il salt.
Si consiglia quindi di non usare informazioni personali per scegliere il salt.


Ma come funziona esattamente?
Prendendo per esempio brainwallet.io, la libreria usata per generare la chiave via browser, usando scrypt, è questa:

Test da browser: http://kclnn.github.io/js-scrypt-async/test_scrypt_browser.html
Codice: https://github.com/kclnn/js-scrypt-async

Le impostazioni usate da brainwallet.io sono:
N = 262144 (2^18)
r= 8
p = 1
# bytes produced = 32

Queste impostazioni potete anche cambiarle, e alzandole il costo di memoria e computazionale aumenterà, fino ad anche non essere nemmeno eseguito dal vostro comune computer ...
Quindi, nel caso vogliate ottenere un impostazione ancora più difficile da forzare, potete farvene una vostra personalizzata, diversa da quella proposta dal sito/codice. (certo, dovrete poi ricordarvela insieme alle parole del brainwallet)

Brainwallet.io, in una qualunque delle scelte per il salt che mettete, mettera uno di seguito all'altro i dati inseriti.

Quindi se i dati saranno, ad esempio:
Name: Gino
Email: gino@gmail.com
Phone: 9836873346
Date of Birth: 04/12/1940

Il salt sarà allora:
Ginogino@gmail.com983687334604/12/1940

Quindi, usando certi dati, e la vostra passphrase, otterrete da brainwallet.io una chiave privata, potrete ottenere la stessa dal sito già indicato sopra:
http://kclnn.github.io/js-scrypt-async/test_scrypt_browser.html

In "Password" dovrete inserire la vostra passphrase, nel "Salt" appunto il vostro salt.
Mettete poi le impostazioni indicate sopra, e generate l'hash.

Tale hash, prendetelo e andate ad inserirlo nella sezione "Brain Wallet" di:

Sito: https://www.bitaddress.org
Codice: https://github.com/pointbiz/bitaddress.org

Otterete cosi la stessa chiave privata generata precedentemente da brainwallet.io.

Riguardo al cambio su localbitcoin da bitcoin a contanti, faccia a faccia, difficilmente rimarrebbe qualche traccia.
Certo nel tu fossi già un preciso bersaglio, perchè magari sospettato di terrorismo, le cose cambierebbero, magari potrebbero anche chiedere a localbitcoin eventuali informazioni su di te.

Anche Bitstamp, nel caso gli venga fatta richiesta firmata da un giudice, è "probabile" (anche se non certo), che darebbe accesso  allo storico dei tuoi trasferimenti.

I guai spesso non arrivano da soli, basta anche cercarseli Wink
3238  Bitcoin / Bitcoin Discussion / Re: #Blocksize Survey on: August 26, 2015, 10:28:27 AM
Not working on paper? So Bitcoin, being vulnerable to a 51% attack as it is, does not work? The code for BIP101 solely exists because of its simplicity, and it has not been tested either. Have 8 MB blocks been tested? Not really,thus the same principles apply.
Gavin has made tests up to 200 MB.
Simpler the better Wink
