781  Bitcoin / Development & Technical Discussion / Re: Matching public key with directory.io - why so difficult? on: September 22, 2017, 10:58:10 AM
At the very first moment when you visit directory.io to find the page number of your offline created private key, it will be very easy for the admin of the page to steal your funds immediately PLUS your offline generated key is not offline anymore. There is no need to repeat the visit, because the attacker (admin) can simply check all visited directory.io pages and check the balance of all private keys on that very page.

You obviously didn't read my posts! I was thinking about USING directory.io as an offline wallet generator - IF I could get the code offline. Unfortunately, the creator hasn't made the code downloadable.



No?

Only for the fact, that Ross posted his real name here on Bitcointalk, I would assume, that his OPSEC was on an extremely low level.

If Satoshi would have founded SilkRoad it would be functioning more like in the style of OpenBazaar. Not saying that Manfred Karrer is Satoshi.
Btw OP you said 'Most people can agree Satoshi is american'. Did you count or how do come to a conclusion like that? Many people actually think Satoshi is british, but a good opsec could include changing writing style, to let the people think he was british.

They do because they think, that Bitcoin makes them completely anonymous, which is wrong, just like most of the answers here.  Tongue

Nothing will happen to Bitcoin, because banks are already working with virtual currencies using encryption right now. They will never issue a crypto currency, that

a. is confirming transactions completely decentralized
b. people can mine with their computers
c. has a public ledger
d. has a limited amount
e. is open source
f. ...

Means, that everything a bank will issue might even be called "Cryptocurrency", but it will definitely not replace the idea of Bitcoin.

I don't understand why you are so fixated on choosing your own private key that is memorable. Why not instead generate random private keys until you generate something that you find memorable. That is far more secure than you choosing something memorable.

These are just ideas and this is just a discussion. I'm the type of person that delves and delves until I find myself answering other people's questions on whatever it is I'm investigating.

A random private key will never be as memorable to me as something I create myself. So there's a trade-off either way you go.

It can be stolen the moment you decide to spend the coins and have to enter you private key into some software. Even if you are keeping the coins in long term storage, at some point in the future you will want to move those coins out of storage to do something with them. Whenever you do that, you expose your private key and it can be stolen.

Similarly, the same argument can be made for randomly generating a private key and keeping it on a storage medium that never touches the internet.

There is also still a significant privacy loss even if you are only using that address for receiving. For starters, everyone that sends you money will know how much money you have. Furthermore you are reducing the privacy of everyone that transacts with you because anyone will be able to look at their transactions and immediately know who they were paying and how much.

Once again, you're assuming I'm reusing this public address over-and-over again or that I'm advertising it. This is my storage wallet and not an address for people to send me funds. True, if I bring them out of hibernation it increases their vulnerability. Then I go down the path of p2p wallets, etc and find a new cold address to send my savings to.

At the very first moment when you visit directory.io to find the page number of your offline created private key, it will be very easy for the admin of the page to steal your funds immediately PLUS your offline generated key is not offline anymore. There is no need to repeat the visit, because the attacker (admin) can simply check all visited directory.io pages and check the balance of all private keys on that very page.

Nice BBC documentation about SilkRoad: https://www.youtube.com/watch?v=pACWVg5Y5zM

VJ mentioned from 56:40. They got pretty exactly the moral turning point of VJ and Ross from their libertarian view into simple violent drug kingpins. PoM's answer to my question regarding this conversation (on MPG pm), was more like some other person used the VJ/Cimon account.
This is a very interesting watch, I would recommend doing so if you have a space hour and a half.

Unfortunately, this really does not talk about VJ very much, except for one small scene.


Interestingly enough, many people interviewed close to Urbright find it hard to believe that he would have ordered all those killings.

As far as I remember, there was a second guy arrested in Thailand in connection with Thomas Clark. I've never read more about it, though.

Market manipulation is not illegal when it comes to cryptocurrencies. It's a paradise for traders, who know what is possible.

795  Bitcoin / Bitcoin Discussion / Re: There is NO Central Authority – Like the Federal Reserve – Behind Bitcoin on: September 15, 2017, 07:08:50 PM
Most of us are here exactly because of this.

From the Bitcoin whitepaper: https://bitcoin.org/bitcoin.pdf

Quote
6.
Incentive
By convention, the first transaction in a block is a special transaction that starts a new coin owned
by the creator of the block.  This adds an incentive for nodes to support the network, and provides
a way to initially distribute coins into circulation, since there is no central authority to issue them.
The steady addition of a constant of amount of new coins is analogous to gold miners expending
resources to add gold to circulation.  In our case, it is CPU time and electricity that is expended.
The incentive can also be funded with transaction fees.  If the output value of a transaction is
less than its input value, the difference is a transaction fee that is added to the incentive value of
the   block   containing   the   transaction.     Once   a   predetermined   number   of   coins   have   entered
circulation, the incentive can transition entirely to transaction fees and be completely inflation
free.
The   incentive   may   help   encourage   nodes   to   stay   honest.     If   a   greedy   attacker   is   able   to
assemble more CPU power than all the honest nodes, he would have to choose between using it
to defraud people by stealing back his payments, or using it to generate new coins.  He ought to
find it more profitable to play by the rules, such rules that favour him with more new coins than
everyone else combined, than to undermine the system and the validity of his own wealth.
796  Bitcoin / Development & Technical Discussion / Re: How to design a perfect cold storage? on: September 15, 2017, 04:26:48 PM
I would start with creating the private key for the cold wallet with a coin or dice instead of a computer rng.

Tell your grandma to quit having weak hands

She believes in bitcoin, she just got a loan from her a bank to buy more because she believes it will rise again. She constantly checks out the reddit and everyone there says it will rise again.

You have a very smart grandma.
