7101  Bitcoin / Development & Technical Discussion / Re: Lock funds in transaction A until transaction B? on: March 13, 2016, 05:58:27 PM
I am learning about Bitcoin script, and wondering if something like the following is possible:

Is there a way to create a transaction which will lock funds until another transaction from someone else with a certain metadata exists?


You cannot lock them until a certain transaction exists. However, what you can do is have a script can only be spent from when a certain secret is known. That secret could be published in another transaction.

You can also lock to a certain date or block height.

I have a suggestion. Why not create perma-links, so someone trying to sell his account could put a link to his analysis in his signature ?
There are Permalinks, kinda. Under the token there is a link for "Share this estimate" and that will link back to the estimate once it generates. The estimate only stays on the server for a week though so that link will only work for one week. This is so that storing the estimates doesn't crash my server.

That's not what I exactly meant. By "permalink", I meant a token that never expire, so you could put a signature and won't have to replace it every week. A small fee, could be taken, like 0,001BTC to cover the stress on your server. However, I would prefer to have this feature for free.
I considered doing that and I actually was going to, but life happened, I got lazy, and it just never happened. Once I get some more time I will resume working on this.
7103  Other / Beginners & Help / Re: Is there any bitcoin debit card for US? Which is the best and your most liked? on: March 13, 2016, 02:51:18 PM
Hello, I am looking into bitcoin debit card, such as xapo.com, but they do not accept United States residents, are there currently any that accept United States residents, if so, which so, and which is your favorite?

Thank you.
I have been using Wagecan's virtual debit card. I like it and it does work in the US. The only problem I have is that loading the card can sometimes take up to two days.
7104  Other / Off-topic / Re: My passwords are stolen when using Tor non-HTTPs ? on: March 13, 2016, 02:15:01 PM
Hello,

on http://en.bitcoinwiki.org/Tor i read:

Quote
(the exit node) can see everything you do on HTTP sites, and can steal your passwords

is this statement still valid and when i submit login form on HTTP site, im actually sending my password to the Exit node owner?

if that is so, is there any way to prevent exit node see my password when login form support only HTTP ?

Or any plugin that notify me before submitting HTTP form password?

Thank You
Yes that is true. It is true even when not using tor. If you are sending data over HTTP, it is unencrypted so anyone between you and the site (e.g. tor exit nodes, routers, switches, proxies, etc.) can intercept and read the data in clear text. This includes passwords and sensitive information. The solution is to use HTTPS. IIRC the tor browser comes with an extension called HTTPS Everywhere that forces sites to use HTTPS if it us available. If it isn't, I think the extension will warn you.

Sorry
Needed a coder escrow for a deal.

Regarding this I suppose: https://bitcointalk.org/index.php?topic=1392185.msg14175242#msg14175242.

Yes, I do code and I can read and understand code. If you would like me to escrow a deal, please send me a PM.
7107  Economy / Services / Re: [ANN] Knightdk's escrow service on: March 13, 2016, 01:07:41 AM
Can you code ?

Thanks

Depends on what you want, but that is off topic for this thread.
7108  Bitcoin / Armory / Re: Armory crashes while "organizing Blockchain" on: March 12, 2016, 10:55:40 PM
Hm. I'm not sure what is wrong here, you will probably have to wait for goatpig to respond.

What was the error that you got when it crashed?

Try starting Bitcoin Core manually. In Armory, go to the settings and uncheck the option to allow Armory to run Bitcoin Core in the background. Then start Bitcoin Core and restart Armory.
7109  Bitcoin / Armory / Re: Armory crashes while "organizing Blockchain" on: March 12, 2016, 10:28:31 PM
Thanks again for your help.  This forum won't let me post either log because they are over 64000 characters.  Is there a way around this?
use pastebin.com and post the link.
7110  Bitcoin / Armory / Re: Armory crashes while "organizing Blockchain" on: March 12, 2016, 08:21:27 PM
Thank you for the response.  I've tried to access the logs but when I try to "export logs"  its says that feature is disabled and I need to "submit bug report".  When I do that I get an error message
Go to the data folder. It is in %appdata%/Armory in windows or in ~/.Armory on linux. There should be two log files there, post the content of those.

Also, try 0.94 testing. You can download it from https://github.com/goatpig/BitcoinArmory/releases/tag/0.93.99.1.

The export logs shouldn't be disabled, but submit bug report is since ATI no longer is developing armory and their servers are now down.

Can you post your logs here?
7112  Bitcoin / Bitcoin Technical Support / Re: Getting back unconfirmed coins on: March 12, 2016, 03:29:09 PM
Hey, i'm new to bitcoins and i really appreciate your help.
So here's what happened. I had to send bitcoins for a game i want to buy. I did set transaction fee to 0.0005 BTC but i did not uncheck the "Send as zero-fee transaction if possible" box. I thought bt core will try sending bitcoins for free a few times and then send it with a fee but apparently that's not how it works. It's been ~24h now and from what i read in this forum it might never confirm because my fee is 0BTC  Embarrassed
Is there anything i can do to get them back? Thank you for your help.
Here's the transaction info: https://blockchain.info/tx/e3b13756536bdb6c9cced7a11f4eded688ad68b65b6002d3b5c2b0eba1f39bc2
Shut down Bitcoin Core. Then wait a few days and check the block explorers for that transaction. Check multiple block explorers like blockchain.info, blocktrail.com, and blockcypher.com. After a few days the transaction should be dropped from the network and then you should be able to spend the Bitcoin again.
7113  Bitcoin / Bitcoin Technical Support / Re: getTxOut by address on: March 12, 2016, 03:27:35 PM
You could import the address into the wallet as watching-only with importaddress <address>. Otherwise, Bitcoin Core doesn't do address checking stuff, so you can use online apis from blockchain.info, blocktrail.com, blockcypher.com, and many other places.
7114  Economy / Service Discussion / Re: Wagecan Bitcoin debit card- Reviews on: March 12, 2016, 02:54:04 AM
I have used their virtual debit card and I continue to use it. The service is legit and IMO it works very well. I have used that card in many places online. The only caveat with buying stuff with it is that the card is issued from Hong Kong so it may not be accepted in some places. The only problem is loading the card which can take up to two days to load the card with money.
7115  Bitcoin / Development & Technical Discussion / Re: bitcoin-qt v0.12.0 crash on settings on: March 12, 2016, 02:49:47 AM
You should report this at https://github.com/bitcoin/bitcoin/issues. You will get more help there as what you have found may be a bug so they can write a fix for this. When you report this, make sure that you include the specs of the system you are using, including the OS version.
7116  Bitcoin / Development & Technical Discussion / Re: SegWit, OP_RETURN and colored coins on: March 11, 2016, 11:52:01 PM
SegWit changes everything in Bitcoin.
How so? Segwit only moves the signature data out of the transaction.

What's the correct way to create colored coins with segregated witness transactions?
The current way will still work. Current transactions will still be valid when segwit is deployed.

Now I'm not up to date on how colored coins work, but AFAIK they use OP_RETURN, which segwit will not change. Segwit will not change the output scripts except for maybe adding a new op code.
7117  Bitcoin / Bitcoin Technical Support / Re: How to add node to crypto wallet any help please . on: March 11, 2016, 10:29:50 PM
Please be more specific on what you want to do and what you are asking. Are you trying to make an altcoin? What do you "add node to crypto wallet"?
7118  Bitcoin / Armory / Re: 0.94 testing build on: March 11, 2016, 10:29:06 PM
I just noticed that message signing and such is completely busted. I'll update later (working on something right now), or maybe upload a patch if it's something I can write quickly.
I only have problems with verifying signatures, not signing. The signing is working fine and those signatures can be verified in Bitcoin Core.

Edit: I wrote a fix here: https://github.com/goatpig/BitcoinArmory/pull/20
7119  Bitcoin / Bitcoin Technical Support / Re: exactly how does a node find its first connection on: March 11, 2016, 08:20:44 PM
The program comes with a list of large stable nodes
My understanding is the list is long and it includes very stable old nodes that hardly ever go down.
Actually that is the last resort.

This is specific for Bitcoin Core, it may be different for other nodes.
First the node checks for its own list of peers that it has built. If it is a new node, that list won't exist.
Then it will check with several DNS seeds, servers which provide a list of nodes. Those DNS seeds are hard coded into the client.
If for some reason the DNS seeds aren't reachable, then it resorts to its own internal hard coded list of seed nodes. Those seed nodes are nodes which have had a super high uptime so it is likely that the node will be able to connect to those.

Thx for the reply Smiley
If you would like to disclose how much you earn from it & what ad network do u use?
I don't get many views since the site is super specific to one thing on bitcointalk so I don't make much. But if you make something that a lot of people will use like something just bitcoin specific, then you will probably make more.

I use a-ads.com.
