Re: BitForex exchange- is it safe?
by
aws
on 04/09/2018, 17:50:49 UTC
I opened an account
deposited some BTC
traded it for ETH
then traded it for the KWATT token
trying to withdraw (fee 30 KWATT)
it says my account is frozen, no additional explanation provided


The account was frozen for 24hrs because i changed my password.
After 24 hrs. i was able to withdraw the tokens successfully

I know this is an old thread, but i just started looking into this right now.
There is also this (master's degree dissertation) project:
Koshy, Diana. An Analysis of Anonymity in Bitcoin Using P2P Network Traffic. Diss. The Pennsylvania State University, 2013
http://fc14.ifca.ai/papers/fc14_submission_71.pdf

Does anyone know of similar projects/papers?

Re: Changing a private key of a public address

Technically each bitcoin address has on average 7.9 X 1028 different private keys that will all result in the exact same address.

can you point me to where you got this information from. thank you.

Based on your prior postings, it is clear you just bought this account.
Your statement to prove or disprove private key collision is very telling of that.

Do me a favor, when you disprove it send me a PM.  Roll Eyes


How did you arrive at that conclusion?

I will share my findings

This is not how elliptical curve cryptography works. Knowing one private key does not make it practically easier to find another private key that collides to the same public key.

thank you, any references to point me in that direction
i want to either prove that it can be done, or prove that it cannot be done

No. If that could be done then none of us would own bitcoin.

think about your statement.
I said that one of the inputs would be the current private key that only you should know

Changing a private key of a public address
by

on 16/06/2016, 20:25:52 UTC
Question:
Since I am not a cryptographer and my cryptography classes gave me killer headaches, this question may have an obvious answer that i am not aware of.
I would like a way to change the private key of a public address, for this you'd of course require the current private key. Is this at all possible?

Why is this useful you ask?
Untraceable transfer of bitcoins.
Why would we want that you ask?
Financial privacy.

Would love to hear from those who have something meaningful to contribute  Smiley

Sidechains: Alpha sidechain Tutorial

Sidechains: Alpha sidechain Tutorial

In this tutorial we will take a practical look at sidechains [1]. We will concentrate on the Elements project [2] and its first sidechain known as Alpha . Alpha is a developer sidechain that is pegged to Bitcoin’s testnet [3]. In order to play around with sidechains in general and with Alpha in particular we need to have the mainchain installed on our machine. The mainchain in our case is the bitcoin testnet. Then we will need to install the Alpha sidechain. Let’s proceed. The instructions below are for Linux Ubuntu.

How does one get this to work correctly.
...
CPU hash: b6064e1a8164cb10e17fc6ff7a38de9420a8950c
GPU hash: 06c7f37ca0b82881f00e1454d0c8837ad91b0531
Found delta: 2527561 Start delta: 41943041

any idea what this means ? is more thats needed to be done thansk in advance
try using it with -S option
Code:
./oclvanitygen 1test -S -v -1 -i -D 0:0  -o 1test_GPU.txt
-S safe mode
-v verbose output
-1 stop after first match
-i case insensitive
-D 0:0 specifies which GPU
-o write output to file

Re: New transaction malleability attack wave? Another stresstest?
by
aws
on 09/10/2015, 05:55:11 UTC
It can be calculated as ( AmountOfElectricuty + CostOfHardWare ) / NumberOfTransactions
How do you calculate cost per transaction in a fiat system, for example the USD?
Think about all the energy that is used by a fiat monetary system.
Same formula, isn't it?


How about cost of employees, cost of real estate, etc. etc. in a fiat system?
I wonder what the cost of the USD system would be.

Re: Could the Federal Reserve Issue Their Own Cryptocurrency?
by
aws
on 20/03/2015, 21:44:08 UTC
This is like the Postal Service announcing they are creating their own "electronic messaging system" like email. Why? What would be the point? It wouldn't save them, and there's no reason to think they'd do it better than is already being done by others. The shortcomings of bitcoin (security and ease of use) are not solvable by the Fed or any roomful of Nobel Laureates, so them creating an altcoin would be pointless. Any innovation they could come up with could just be replicated by every other crypto in existence. The only edge they could possibly get would be regulatory/legal in nature, and it would be blatantly obvious to everyone if such favoritism were put into words. That would simply wake up Wall Street and Mainstream America to the nepotism and how it would be inferior to existing cryptos in the ways that matter, which would end up providing a big boost to real cryptocurrency, even if it had to happen "underground."
This would not be about innovation, but about putting dollars on a blockchain. This way one can send dollars anywhere in the world as fast as bitcoins.
Also this would allow people from other countries to hold dollars, if they wanted to - and a lot of them do want to, without the permission of their local governments.
Don't think about it as an altcoin, but as a US dollar on a blockchain.
