I am curious to know how you are using virustotal?
Do you download on your computer and then upload using their file tab?



Read Danny's comment in last page.

I uploaded the file. Should i worry?

No there is nothing to worry about, and as I said read This]https://bitcointalk.org/index.php?topic=1639722.msg16496231#msg16496231]This. I have also downloaded and checked it with my AV and there is nothing to worry about.

The reason I asked this is because I though there is an easier way to check it directly and not download, upload

Download it from their official website https://electrum.org/#download The windows version.
I download the Standalone Executable or Windows Installer. Version 2.6 and 2.7 are showing as Trojans.

I checked with my AntiVirus (Eset Smart Security with latest virus signature database 14246) there is no Trojan or any other kind of alert.

Check these and report back:
1) Make sure you have downloaded from the right source
https://electrum.org/#download
Standalone Executable: https://download.electrum.org/2.7.2/electrum-2.7.2.exe
sig: https://download.electrum.org/2.7.2/electrum-2.7.2.exe.asc

Windows Installer: https://download.electrum.org/2.7.2/electrum-2.7.2-setup.exe
sig: https://download.electrum.org/2.7.2/electrum-2.7.2-setup.exe.asc

ThomasV sig: https://pgp.mit.edu/pks/lookup?op=vindex&search=0x2BD5824B7F9470E6

2) Check the signatures after you finished downloading. There is helpful link in one of the above comments.

3) Make sure you did not have a Trojan already on your PC from before (like having it from a month ago but not knowing about it)

4) If and only if you did all of the above and you still had the same problem, make a proper report and wait for a developer to see this.

did you check the signature after you finished downloading Electrum?
No I did not.

then get right on it and report back.

i don't know how reliable virustotal is about .exe files but here are the results (all 0/68):

Thanks for your feedbacks.

As respectfully I'd like to appreciate your efforts for putting the stuff on github,

This is the main reason. to make the code open source, get feedback on the code and learn more about coding (look at my name Wink)

Quote
I'd want to point out the main factor which would make your app absolutely a waste of time.That is,the requirements!

I enjoy coding so even if others don't find it useful, I am learning a lot of things in the process and I find it useful for myself that is why I created this in the first plce.
2 weeks ago I couldn't imagine designing the Xaml like what you see in the first post.
A month ago I didn't know how to use Github now i am pushing commits properly to my new branch.
A couple of months ago i had no idea how to use API and now i have this as my tiny side-project and 4 other projects 1 of which is a trading utilities which i am up to 2000 lines of code.

Quote
-No everybody uses web wallets,electrum pretty much gives the same service to watch my wallet addresses.

It is mainly about the size, Electrum is lightweight but it is still 50 MB installation file + 35 MB headers and wallets files.
this project is 1 MB installation file + < 3KB wallet file

Also i personally like to keep track of the value of my bitcoin. If you look at the left side of the GUI you see three TextBoxes for total bitcoin balance and the value of it in USD and local currency which I can't get in Electrum.

Quote
-Any block explorer would give the results instantly after putting a bitcoin address.Do you really think someone would
 take the pain of keep a 3rd party app running and refreshing the stuff to get the latest results ? I doubt it.

It is more like a log book to keep track of ALL your money (public keys)!
For example I have multiple bitcoin addresses which I want to keep them all in one place and not have to copy each address, open a browser and paste one by one to see what the balances are and then open up a calculator to calculate how much it is worth especially in my local currency!



Thank you for uploading your BTC wallet to GitHub! I'm learning C# in my free time and I keep your upload an useful resource. Since it's open-source, I hope I'll be able to contribute some nice features in it soon.

If I see more C♯ Enthusiasts around here I may publish more of my projects on Github.
I'll be glad to see your contributions and help you in any way i can in learning C♯.

please do the following:
at the bottom right side of the Electrum window click on the green circle or got to Tools > network

then report what does it say in the first line of that window.

it should be Blockchain: 433108 blocks. right now (or a bigger number depending on when you check it.)
933  Bitcoin / Bitcoin Discussion / Re: What's wrong with my current cold storage? on: October 05, 2016, 06:38:42 AM
Bitcoin is all about the edge cases and being fully informed, I don't think there is any overkill in the comment but perhaps you can tell me what you think is overkill?
What does erosion have to do with this that corrosion does not cover?

i agree about the edge cases but lets review your edge cases that you have been focusing on in your first post (corrosion, melting point, and you mentioned hard to machine which relates to hardness if we want to engrave physically and doesn't matter much if we want to laser-engrave)

keep in mind corrosion is a process, not a property.
Corrosion:
when we talk about corrosion it is all about the environment, put simply there are two categories to watch: corrosion that is not influenced by any other process and corrosion that is influenced by another process, such as the presence of stresses or erosion (Erosion being a wear process, in which surface damage is caused by the repeated application of high localised stresses)
since the wallet is going to be kept at home environment, lots of conditions like stress induced corrosion cracking are not relevant.
the only things that we have to think about are "Aqueous" and "atmospheric" Corrosion. so strictly speaking a carbon steel with a simple coating is going to do the trick.

melting point
again room temperature and a case of possible fire to reach a temperature of as high as 1100°C which is still inside working temperature of steels.

Quote
> the hardness of these materials is what you should look for

hardness is good but as we see with tungsten being so brittle it isn't a end all be all. I agree that stamping on steel is the best for the common man, I update the Al part to reflect the potential melting point

you misunderstood the meaning of "brittle". a brittle metal is a metal that breaks catastrophically when it reaches the UTS point.
we are talking about a metal, so tungsten with a Yield strength ~ 1000 MPa (it is 500 ish for SS) needs a tremendous amount of power to be broken.
i am not saying use tungsten , just pointing out what brittle means Cheesy

Quote
The titanium is actually only about 10% more expensive than the 316SS

you didn't say which alloy though.
you are intriguing me to buy one and do a quick XRD to find out Cool
934  Bitcoin / Electrum / Re: [Suggestion] Issue Refund on: October 03, 2016, 04:57:26 PM
it is suggested not to do Address reuse and many users are following this suggestion. this means your suggested feature is either encouraging address reuse! or is not going to work because the sender no longer wants to use that address or may not even have access to it because of using an Exchanger, an online wallet like Coinbase,...

Electrum is already showing addresses in a way that some believe is encouraging address reuse. so i don't think it would be a good idea to add to that.

also bitcoin is a no charge-back-currency so i find the idea of "refund" a bit redundant.

935  Bitcoin / Bitcoin Discussion / Re: What's wrong with my current cold storage? on: October 03, 2016, 10:44:19 AM
there are a lot of overkill in your comment and since my expertise lies in the following part i try to explain my thought:

Engraved / etched/ ablated/ stamped on a piece of metal
 * Some metals can deteriorate or corrode, choose a good metal; also store your metal away from direct contact other metals. Some metals that are corrosion resistant have low melting points, are extremely expensive, orhard to machine.

lots of the links about corrosion, erosion (that you missed the link to), melting point, maintainability, etc are used for harsh/corrosive environment which contains acids like in the food industry, and as for machining, forming,... the hardness of these materials is what you should look for and a simple Austenite Stainless Steel has enough properties to be able to cut the big plate in the form of a paper wallet and then engrave on it using a simple chisel.

Quote
Previously we had been working with 316 Marine grade Stainless Steel for the Keyois capsule engraving material, it is the best type of steel my research led me to, however we made the switch to  Titanium  because it is even better.

is your research a self google search or is is a consult with a material science expert?
if you ask me i say you have increased the cost at least 20 times by choosing Titanium and gaining not much properties over the stainless steel.

Quote
* Metals can still deform or melt from heat, destroying any engraved SK.
"Most house fires do not burn hotter than 1,200 degrees Fahrenheit. This temperature is typically associated with the hottest portion of a home, which is in the roof area. Homes that burn for longer than 30 minutes or consist of multiple levels sometimes burn at higher temperatures."     
You want to pick a metal that won't be destroyed by a fire. So Brass, bronze, tin, lead, silver, gold, and copper are all out as engraving materials.     
Aluminium should survive but I haven't tested this.

Aluminium properties can range from a melting point of 460 °C (865 °F) to 1500 °C (2800 °F) but the price is also going to go up!

Quote
At around 1500° Steel and Nickel should be okay.     
Titanium is what the Keyois Capsule has the SK engraved on and it has a melting point of over 1600° C / 3000°F. Tungsten is double that but can be brittle.

i am curious to know which Titanium alloy it is used in this product.


Austenite Stainless Steel is most probably more than enough for this particular usage, and if you are worried about some properties like the strength, more corrosion resistance, a better surface, a better resistance to Pitting there are some alloys that have structures made out of a mixture of Austenite, Martensite, Ferrite which are so much cheaper than Titanium with enough properties to satisfy any possible threat.

i will post more information with my CES if i had time!
936  Bitcoin / Development & Technical Discussion / Re: API Pulls to display things in the wallet software on: September 30, 2016, 07:17:44 AM
Would it be possible or maybe it already exists for Bitcoin wallets to display Twitter feeds, or perhaps even a graph displaying the current price/volume.

bitcoin wallet is just a software like any other software so adding these features is not hard or unheard of but some of them have no use so nobody wants it like twitter feed! why would anyone want to see twitter feeds on his bitcoin wallet?!

but price is useful and it is already implemented in Electrum (i don't use other wallets to know more) it is in the plug ins window.

Quote
What are the potential risks (if any) to having these API pulls in the wallet software. Can the site who is have their data "pulled" see the IP/Computer info of the wallets pulling it and maybe compromise the anonymity of the person?

to my knowledge there is none (but i may be wrong) because it is a string (json or other formats) that you receive and work on that so it can not be in any other format or like be malicious! it doesn't make sense to me.

as for your IP, yes the site sees your IP based on your code you are just asking the site "give me price" nothing else so the site sees this "IP address XX.XX.XX.XX is asking for price through an API call" that is all. (unless your wallet is shady and sends more information intentionally Cheesy ) in other words there is no way an API call to get price for example can reveal your bitcoin addresses.

Quote
I know Satoshi had mentioned adding a way for him to broadcast a message to the all the connected wallets, but wouldn't a twitter feed that displays on a tab in the wallet be more practical?

my knowledge about this matter is limited but there is a difference between sending a message through channels that satoshi had in mind (like alert keys) and a twitter (third party and potentially insecure) channels.

Quote
Having wallets display info from other sources seems like a neat addition to a custom wallet, what are some reasons why/why not someone would use a wallet like that?

the following are Electrum plug-ins and to be honest i have no idea what half of them do and i don't care either because i don't find any of it useful for me



is there any particular feature other than twitter feeds and price you have in mind?

939  Other / Bitcoin Wiki / [Fixed] I found a tiny problem in a link on WIKI on: September 29, 2016, 12:53:35 PM
I don't know if I should report this here but here it goes:

In this page https://en.bitcoin.it/wiki/OP_RETURN in the second paragraph the link to github pointing to 80 bytes has an a character in the end which is extra https://github....snipped... q=MAX_OP_RETURN_RELAYa

wrong:
Code:
Currently, the default Bitcoin client relays OP_RETURN transactions up to 80 bytes [https://github.com/bitcoin/bitcoin/search?utf8=%E2%9C%93&q=MAX_OP_RETURN_RELAYa], but does not provide a way for users to create OP_RETURN transactions.

corrected:
Code:

940  Bitcoin / Bitcoin Discussion / Re: Unable to decode output address on: September 29, 2016, 12:45:57 PM
OP_RETURN allows you to put 80byte long (IIRC) hex string in the blockchain.

That got cut down to 40 bytes, I believe

it is still 80 bytes as it is also said in the Wiki


Well, I remember the 2nd layer alt-coin camp complaining about it getting cut to 40 bytes, but I guess that didn't happen in the end. Accept my apologies.

Or was it cut to 40, then increased back to 80 again in Bitcoin 0.11, maybe?

THE HISTORY

i suppose yes in 2014
