701  Bitcoin / Project Development / Re: [C#][Github] Watch Only Bitcoin Wallet. Keep track of balance and price(V2.2) on: June 25, 2017, 08:16:33 AM
Released version 2.2.0
  • A lot of small code improvements
  • Exceptions are handled and a couple of bugs fixed
  • The Error MessageBox is now hidden and will only appear if there is an error
  • Added a new StatusBar at the bottom of the window
  • Added a new API service for fetching balances (blockr.io)
  • The balance now has a ToolTip showing the difference each time balance is updated
  • Important: Wallet file is not stored in JSON format which makes this new version backward incompatible. This new format reduces the wallet file size a lot and is easier to use.
  • Saving is now completely automatic!

Made some code improvements.
Special thanks to https://github.com/dbremner

Bitcoin uses little endian byte order. This is not what you are doing.

Not always! There are cases which use Big-endian.

Make sure to check out the open source webtorrent project that this is using. WebTorrent is a torrent client with some cool features such as enabling easy streaming of torrents on your desktop.

Hah, Funny you should ask:
Web2Web: Decentralized website based on torrent and bitcoin blockchain: https://bitcointalk.org/index.php?topic=1641068.0

I am currently trying it out with an HTML version of bitcoin paper: https://bitcointalk.org/index.php?topic=1959694.0

p.s. I am not familiar with siacoin, should check it out.
706  Bitcoin / Project Development / I need testers/helpers for a project (web2web decentralized website) on: June 10, 2017, 05:15:42 AM
Here is the story!
Some time ago I found a cool project on GitHub called web2web. I even made a topic about it, but it seems like not that many were interested!
You can read the repository and that topic for more information on how it works.

Now what I need help with:
I am not so familiar with torrents, and so far I've just downloaded them. Never the other way around, and having a slow connection is a bit of problem too.

I've made an HTML version of bitcoin paper some time ago using an online tool called cloudconvert. Here is the torrent file:
This is a magnet link, you can just click on it to open your torrent client and start downloading. You can do it in a sandbox if you like, you can also see the file here on my dropbox (file size is 344 kB)

First step is finding out if I have made the torrent correctly or not.
https://instant.io/ (side project of webtorrent) can not download it and I have no other way of confirming it.
Also it would be cool to get some more seeders to speed up the process.

Second step is to checking to see if I can make the website to work using Web2Web.
You can check it live in here: https://elendirx.github.io/web2web-gateway/#/
Suffice it to say that I have not been able to make it work, don't know if the problem is from the torrent file or the slow internet connection I have!

Third step would be saving the torrent hash on the blockchain (read web2web details for more detail).

P.S. If you know any method of free online seeding, like on a server it would be great if you could share it here.

Edit: Changed the magnet link to a new one and added some trackers.
707  Bitcoin / Development & Technical Discussion / Re: UASF nodes wrongly reporting IP on: June 08, 2017, 05:11:45 AM
This may be a strange question, or maybe because of my newbishness, but "How do you know it is a bitcoin node?"
I mean I can connect to any node that I have the IP to and successfully do a version handshake! And I am not even running a node, it is a simple Version <> Verack thing and you won't know unless you ask me for inventory Tongue

Can this be ported for use with PortableApps.com?

I am not familiar with that APP but took a quick look at their about page it seems like it will work.
My code doesn't need installing, you just have to compile it and you can just simply transfer the bin folder to any other computer running on windows (since it needs .Net framework) and double click and run it.

Technically the whole bin folder is not even required. It will need only these 3 files:
Code:
MVVMLib.dll
Newtonsoft.Json.dll
SharpPusher.exe
710  Bitcoin / Project Development / Re: [C#][Github] SharpPusher, broadcast bitcoin transactions to the network on: June 02, 2017, 04:09:46 AM
push {tx} -1 (where 1-n will be a list of services)

If you mean something like a loop to push to multiple services one after another, then it is pointless because if you successfully push your transaction to the network it propagates fast within seconds.
Which means by the time the app goes to the next service, it already has your transaction and will most probably rejects it because it exists in its mempool.

Just a little project:
SharpPusher, broadcast bitcoin transactions to the network



Just some points:
The blockchain.info API has proven to be a bit tricky! So please let me know if you encountered any weird responses.
This is for Windows only (sorry!). But I have .Net core in my learning backlog and will make it multiplatform in the future, hopefully.  Grin

      I actually ran it through my code in debug mode inside VS and it gave me the error that a non-base58 char is there Cheesy
      714  Bitcoin / Bitcoin Discussion / Re: How bitcoin addresses are generated? on: May 31, 2017, 04:46:05 PM
      What exactly does SHA1 have to do with any of this? Private keys turn into addresses via EC point multiplication followed by SHA256 (which is a member of the SHA-2 family), followed by RIPEMD160.
      Said it mostly because of this:
      was wondering how safe SHA256 is.
      Thought it is a nice little info to share here.
      715  Bitcoin / Bitcoin Discussion / Re: How bitcoin addresses are generated? on: May 31, 2017, 04:32:39 PM
      The theory about an approach to successfully create a SHA-1 collision was published in 2013.
          Nine quintillion (9,223,372,036,854,775,808) SHA1 computations in total
          6,500 years of CPU computation to complete the attack first phase
          110 years of GPU computation to complete the second phase
      Went into the testing of the theory.
      In February, 2017 they finally succeeded at finding a collision.
      Now we are using safer cryptographic such as SHA-3 and SHA-256

      I found your problem Cheesy
      try this link: https://blockchain.info/address/1DJJoJ4sxwJdwExTsoDg8qXL1FEozDGQEF

      You have a hidden charter between g and 8, the copy was messed up for some reason!
      1DJJoJ4sxwJdwExTsoDg­8qXL1FEozDGQEF

      Ok, what exactly is the problem cause i don't understand it is. Just a bunch of info about transaction details.

       Huh

      The problem is that this 1DJJoJ4sxwJdwExTsoDg­8qXL1FEozDGQEF has an additional character inside of it which is located between the two letters I made bold above. It is hidden so when you put it as the bitcoin address the code sees it but not you, so it finds it invalid.
      When you remove that character it becomes this 1DJJoJ4sxwJdwExTsoDg8qXL1FEozDGQEF which is a valid bitcoin address.

      Ask him to give you the QR code of the bitcoin address. QR has a built in error thingy in it which prevents any copying problem. He may have copied part of the address. For example it may be missing a letter at the end!

      Even if you don't have a smart phone you can use an online tool to convert the QR into string (address in this case): https://webqr.com/

      Yeah, that's why I didn't post it. I could never push anything with Moloch's tool!
      The same with webbtc, it was working for some time but I guess their node is no longer updating. It is stuck on block 443888.

      The wiki has a couple more


      And of course my favorite method ... drum roll ... Push directly to the network by contacting nodes via a simple code. Basically the "Sending a transaction: tx" part of bitcoins hard way article.
