1  Local / Discussions générales et utilisation du Bitcoin / Armes des attentats de Paris, achetés avec Bitcoin ? on: November 27, 2015, 10:35:54 PM
http://news.yahoo.com/weapons-used-paris-attacks-bought-german-dealer-report-085607402.html

Apparemment les armes de guerres ont été achetés sur le deep web.

Une personne soupçonné d'avoir vendu les armes est détenu par les autorités allemandes.

Qu'en est-t-il de la place du Bitcoin dans cette histoire ?
2  Bitcoin / Bitcoin Discussion / Guns from the Paris Attacks, bought using Bitcoin ? on: November 27, 2015, 10:32:15 PM
http://news.yahoo.com/weapons-used-paris-attacks-bought-german-dealer-report-085607402.html

Apparently the assault rifles were bought from the dark web.

A suspected seller is held by the german authorities.

Any thought regarding the place of Bitcoin in this story ?

6  Bitcoin / Mining / Generate fake hashrate to test client & server resources on: August 08, 2013, 02:42:42 PM
In a controlled environment on both side (mining-client & mining-server), how can one generate fake hashrate on the client side, get it accepted by the server as valid to generate fake bitcoins, so one could test the hardware resources of the server (and the client as well).
7  Bitcoin / Mining / Eloipool or stratum+stratum-mining? on: August 05, 2013, 11:18:26 PM
Hello,

I'm considering using one of these two software (eloipool or stratum+stratum-mining) to run a heavy stratum mining pool.

My basic concern is performance, which one is more scalable/efficient?

Also the second part of my inquiry is the overall support and resources available (i.e. how much work is needed to implement an Auto_add_user functionality similar to 50BTC) to work with the coinbase distribution and share logging.
8  Bitcoin / Development & Technical Discussion / multi-signature transactions in javascript on: July 24, 2013, 12:22:42 AM
Hello,
Does any example of generating (from inputs + privates keys) a multi-signature transactions exist in any language? What about Javascript?

10  Bitcoin / Bitcoin Discussion / Poll: How many of you did actually read Satoshi's paper? on: May 31, 2013, 04:34:06 AM
I was wondering that, I'm into Bitcoin since 2012 but didn't actually read it.
11  Economy / Speculation / I was thinking on: May 28, 2013, 10:24:47 AM
In 5 years, when the final banking crisis arises, and the whole banking system collapses. Having a "price" for bitcoins in USD or EUR doesn't make sense anymore. The "price" is basically infinite then. BUT the value is not, although still bigger than now.
12  Bitcoin / Bitcoin Discussion / Security problem on: May 18, 2013, 01:57:20 PM
Case 1: A thieve tries to steal fiat money online
1. He develops a widespread malware that tampers with lots of money processors and bank webpages, directly on the browser of the user's machine
2. Steals logins/passwords
3. Steals 2-fact codes and within the window of validity (from some seconds to some minutes) withdraws money
4. Issue: can't transmit the money to him directly or he will get caught
5. Even if he succeed to launders the money, the honest customer gets his money back from the bank and the money processors

Case 2: A thieve tries to steal bitcoins online
1. He develops a widespread malware that tampers with all the exchanges webpages, directly on the browser of the user's machine
2. Steals logins/passwords
3. Steals 2-fact codes and within the window of validity (from some seconds to some minutes) withdraws bitcoins
4. Profit
5. Honest user is screwed, must file a police alone

Only fix for the Bitcoin user is to secure its computer. No other choice.
This is my security problem, how do we solve this for lambda users?
13  Economy / Service Discussion / Paypal asking if I received the BFL product I ordered back in August on: April 22, 2013, 06:58:33 PM
Hello,
Just wanted to share that Paypal just called me, and they asked if I did actually receive the BFL product I paid for back in August.
I told them no, but I also told them not to worry because "the company is actually telling us they will ship soon".

 Undecided
14  Bitcoin / Mining / ASICs and blocksize on: February 25, 2013, 09:49:01 PM
Hello,
I want to add to the current discussion about the blocksize, that the security of the network does NOT only depends of the tx fees.
People forget that a lots of people are today buying ASICs, and will in the future. This is what render the network secure on the longterm.
Or does it?

Hello,
What pool accept mining through the port 80?
16  Bitcoin / Bitcoin Discussion / Bitcoin and Iran (also North Korea, etc.) on: January 13, 2013, 04:33:23 AM
Hello,
2 quick points on Bitcoin (as a network of exchanging money):

Security: We know the Bitcoin network is secure for now, and I believe it will stay so, I trust Gavin more than anything on this subject (being an early adopter has to be a good motivation to always have security as priority #1, and this is good).

Usability and Philosophy: I believe in Bitcoin, and so do we all here (almost), it is our duty to somehow make something out of it. People will eventually see the use in the Bitcoin as we see it, it's just a matter of time. I just happen to have one problem with that: The "official" embargo the Bitcoin "officials" (read important persons here) have imposed against Iran, just like US dollars. What the fuck is that? Why wasn't there an uproar against that? This is part exactly why bitcoin was created, this is the roots of the idea of Bitcoin, and yet people do the same things all over again. If Bitcoin can't be used in Iran because of the MIT licence of the source code of the original client, then people we have a much bigger issue than the network security to address.
17  Other / Off-topic / Is bASIC trying to delay BFL shipments plan? on: November 27, 2012, 03:52:13 AM
bASIC went from 27 GH/s to 54 GH/s, to now 72 GH/S for $1069.99.
BFL from 40 GH/s to 60 GH/s for $1299.99.

Is Tom using all of his ressources to force BFL to adapt to these numbers, thus delaying BFL shipment plan? Maybe because he has not his bASIC chips himself?

I would do the same in his position.

19  Bitcoin / Development & Technical Discussion / SHA-256 broken, collisions found... Bitcoin then? on: October 25, 2012, 03:54:54 AM
Hello,

So my understanding is that Bitcoin relies at its core on SHA-256 to ensure it is secure and works. Since RIPEMD-160 is just a shortening layer, and nobody seems to worry about the ECDSA secp256k1 curve, let's talk about SHA-256 and Bitcoin.

It is just a matter of time before SHA-256 gets broken. By brute-force we are fine (centuries, or centuries/2 with quantum computing).
But what about flaws in the "design", like every other cryptographic hashing algorithm before, it will be broken down by cryptanalysts. Question is when? 5 years? 10 years?

2nd Question: how is Bitcoin network going to react? Are there already plans for this?

Some links I gathered while quicksearching on the subject:

20  Alternate cryptocurrencies / Altcoin Discussion / What are the uses of Namecoins (NMC)? on: October 01, 2012, 12:35:59 AM
Hello,
Namecoin (NMC) seems to be doing poorly lately. What are the uses of Namecoins? Bitcoins laundering?
