Hey,

i always wondered where the additional fees when sending a transaction come from?
It is 0.0005BTC on top for me, while the regular dynamic fee right now is something about 0.0007.

Gibt es schon ein Crypto Cloud Storage bei dem man sicher und einfach seine Dokumente verschlüsselt online lagern kann ?

Can anyone explain me how the Bitcoin blockchain projects like maidsafe, factom, counterpaty, sia etc. work ?
How are they connected to the bitcoin blockchain?

And the tokens of these coins are stored on a regular bitcoin public address or do i store them somewhere else ?

Hey,

kann mir mal jemand in einfachen Worten erklären, wie die ganzen Coins, die wie ein Layer auf der Bitcoin Blockchain sind, funktionieren?


Und bezüglich Lagerung und Verwendung, nachdem ich sie auf einer Börse gekauft habe.
Maidsafe, Synereo, Factom, Sia, Counterparty, kann ich die Coins alle an eine normale Bitcoin Adresse schicken und die lagern dann da einfach ?
Und wie kann ich sie dann wieder verwenden?

[she never agreed to.]

I want to discuss some issue and see hear opinon on this:


I lend out ETH on Poloniex during the HF.

After the Hardfork i just got back ETH(postfork) which was the new name of the major fork.

In my opinion this is just wrong, since the borrower agreed to lend ETH(prefork) and so hast to give me back ETH(prefork) which is now basically ETH(postfork) + Ethereum Classic.

I think they handled it wrong and gave the ETC to the borrower who just had to give back ETH(postfork) instead.



Their math example : https://poloniex.com/press-releases/2016.07.26-responses-to-common-etc-questions/ is wrong as well imo :

Alice shorts ETH(prefork) by borrowing 200 ETH(prefork) from Bob and selling it to Carol. Carol, who used her own BTC to buy 200 ETH(prefork) in the spot market, withdraws all 200 ETH(prefork) to her Mist wallet ETH Hard Fork occurs Carol receives 200 ETC in her Mist wallet Because the 200 ETH(prefork) Bob lent out is no longer on Poloniex, there is no ETC to give him The only option is to create an additional loan contract that neither party agreed to, wherein Alice owes Bob 200 ETC in addition to 200 ETH Alice is forced to buy 200 ETC in a market she never entered to settle a debt she never agreed to.

This is wrong : Alice agreed to the debt of 200 ETC , because she loaned 200ETH(prefork) which is divided to 200ETH and 200ETC after fork. In your calculation the lender basically could loose up to 49% of value depending on how his ETH(prefork) divides based on the community deciscion, which is just wrong!!! Alice shorted the value of ETH(prefork), so she is responsible for the loss prefork not postfork. She has to get the ETH(prefork) back, which is afterwards ETH+ETC. It could be also ETC being the winning chain, what about that ? so ETH is basically just the winning chain after a fork with lets say 80%, what about the other part of the original ETH ?

When you borrow, you receive an asset and a debt. But in this scenario, Alice is forced to “repay” a principle she never received, and the terms of the loan are changed without the consent of either party.

Alice for sure received the ETC, because it was priced in the ETH(prefork) already so she makes in this case no extra loss btw, because ETH(prefork) value will be divided up in ETH(postfork) + ETC so he can easyly buy with his prefork ETH ETH(postfork) + ETC.
There is nothing added , it is just split and usually after the split ETH+ETC < ETH(prefork) because communities use engery to battle each other first.
You could see this on the market as well, as soon as ETC starts trading, ETH(postfork) lost value.

Maybe this example will help. I lend someone a google stock, now the lender sells the google stock. Afterwards there happens a rebranding, google is now divided up to alphabet and gamma. So on the exchange gamma is rebranded in google , because it makes 80% of original google stock and alphabet only 20%, he only have to give back the google(gamma) part and not alphabet part?

Just because ETH after fork is called ETH, it is not the same like ETH ( prefork) IT is even completely different. It should be renamed to ETHF and ETHC. If you take this serious you could even say, that ETC has more right to be ETH now , because the code didn't change. So however you take it, the lender should definitely get his ETH(prefork) back which he can divide in ETH+ ETC as he wishes.



I think bitfinex handled it correct and gave the lenders back the ETH(prefork) which they can divide in ETH + ETC as their wish.

How do you think about this and is anyone else affected by this ?

Hallo,

ist hier noch jemand davon betroffen, während des ETH Forks auf Poloniex ETH verliehen zu haben?
Meines Erachtens ist es unrechtens den Leuten die Prefork-ETH verliehen haben nun nicht ETH+ ETC zu geben. Der Leiher ist doch dafür verantwortlich, dass er den selben Wert wieder zurück gibt, also in dem Fall Prefork-ETH, was eben nun ETH+ETC sind.

Wenn ja, sollten wir vielleicht gemeinsam rechtlich vorgehen, da dies eindeutig gegen die Vereinbarung ist.

[Edit]

My goal : safe private key import from cold storage and immediately transfer to a specific bitcoin address.


So i heard the safe way would be :

- import private key to offline computer using electrum
- encrypt wallet and copy to online pc via usb
- doing tx on online pc
- copy tx to offline pc and sign it
- moving wallet back to online pc to send it

http://docs.electrum.org/en/latest/coldstorage.html#coldstorage

My questions here are following :

Is it possible to "sign" the transaction to my specific bitcoin adress offline already so it will be executed immediately when i am online again ?
Edit : yes , just did it.

Just wondering what is the difference between loading this signed transaction file in ethereum and typing in my private key ? Isnt it exactly the same when it comes to security ?
I still see no point how it can be hacked, because the transaction you broadcasted will always be faster than the one someone could do after a keylog hack ?


If it is important to to this offline, is it also ok to just do this on another computer which is offline just during the period of this transaction and afterwards online again?

Because i read that for private keys one should use a seperate offline box which is never connected to the internet. But after the transaction is done, it doesn't matter anymore, does it ?

The always offline box is just important for generating cold storage files ?


Apart from all that.
Does it make sense at all using an offline computer ?
I mean just sweeping a private key into electrum should be fine ? even if the computer is unsafe the guy who probably keylogs will always be behind this transaction and has no change to be faster, does he ?



Edit :
I tried to do it like here :
https://m.reddit.com/r/btc/wiki/electrum
But i am not able to do step 3. Save out the Master Public Key from Electrum.  I am not able to click the button.

Then i tried to do it a different way with just the public key, why do i even need the Master Public Key ?

Someone wants to use this service as escrow for localbitcoin transaction.

Is this service any trustworthy ?
