Couple of suggestions:

For transactions, can you have a full breakdown of the exact details of a transaction? Maybe in technical? Also, there should be some way to view the input and output scripts.
For blocks you should have it so that we can view all of the transactions included in the block.

The estimator was better before. It just got messed up after the introduction of token system. I hope it will rectify over time and with few necessary updates for invalid tokens.
I believe that has been fixed now. I can't reliably reproduce the problems we were having earlier so I can't really debug it.

Anyways, I noticed a small loophole in "merchant mode". You need to remove Post Sections Breakdown and Addresses posted in non-quoted text sections (if not the former section, but removal of the latter section is important), because the buyer can easily track the account by clicking on one of his non-quoted addresses.



I think in the merchant mode, that you should remove the Addresses posted in non-quoted text section, as that might shed some light on what the account is. They can just search on the forum the addy, have a good idea what the username is.

Maybe you could censor the address names to just the first and last 4 characters, but vanity addresses might be obvious in telling what the account name is. I think a better solution is to have an option to disable or enable Addresses posted in non-quoted text section.

Oops! I missed seeing your post anyways. Grin

Oh, I totally missed that. I think the post sections breakdown is fine to stay, it doesn't say how many posts, just activity, so it is harder to determine the account. The addresses though, that is a problem I will soon be rectifying.

Fixed the local roots not showing, was an issue with my settings.
That is quite helpful. I will see about implementing that so it properly shows the sections.

Edit: Shorena, you missed a section: Local / Projektentwicklung /
Also, the site has been fixed and updated. Any previous tokens are now invalid.
7803  Bitcoin / Project Development / Re: Introducing OXT, a tool for Exploratory Blockchain Analysis on: January 09, 2016, 07:49:58 PM
This is a great site and I think it rivals walletexplorer.com. It is the only other site that I know of that groups addresses together.

Is this site open source?

7805  Bitcoin / Project Development / Re: Bitcointalk Account price estimator on: January 09, 2016, 07:10:42 PM
Works, thanks. I see you also fixed the sections, very nice. Only node.jps: 1 Posts makes me wonder if there is such a section.
There isn't. There is still a slight problem with the sections when people create topics that have slashes in them. That section it sees happens to come from this thread: https://bitcointalk.org/index.php?topic=1307971.0 which has two slashes in the title.

which is my title Sad

I guess you would need some sort of database to match against, right?
Yes, but that list would be rather large. I just didn't want to go through and find every section that you can post in in the forum. If there was such a list it would fix the problem.

7807  Bitcoin / Armory / Re: Transaction Stuck Need Help Please: Non-canonical signature: High S Value on: January 09, 2016, 06:38:50 PM
What happens to the BTC I sent already? How do I cancel it without losing the coins? It is stuck at 0 confirmations. I know it's rejected but my wallet still has it pending.
The transaction probably doesn't exist on the network. Go to Help > Clear All Unconfirmed to remove it. Then you can send again.
7808  Bitcoin / Armory / Re: Transaction Stuck Need Help Please: Non-canonical signature: High S Value on: January 09, 2016, 06:27:54 PM
I sent a payment with v93.1 and v11.0 because Mac issue. Now I sent BTC and got this "Transaction isn't Transaction rejected by our node. Reason: Non-canonical signature: High S Value". I noticed there is finally a 93.3 available for Mac so I download and upgrade to 11.2. What do I do next to get that BTC moving? Thanks for your help.
Just send the transaction as you normally would. 0.93.3 fixes the High S problem.
7809  Bitcoin / Project Development / Re: Bitcointalk Account price estimator on: January 09, 2016, 06:08:51 PM
Thanks, good to know, I got some problems since a few days too. Mostly it's not updating my que one the website.
Too bad visitorsbit.com is gone btw.

Got this message now:
Your token is 7t7e73br

Something has changed.

Does someone knows for whatthe merchant option is  being used for?
The merchant option is for account sellers. They can post the link to that token so that prospective buyers can check the stats of the account without actually giving away what that account is.
Alright, lets see how its working

Share this estimate: http://www.bctalkaccountpricer.info/?token=n6518rpr

Again returns "invalid torken".
I'm checking it out.

Edit: Shorena, it looks like that problem happened to a few people according to my logs. I don't know why it happened but it fixed itself. I submitted one for you here: http://www.bctalkaccountpricer.info/?token=7jasl1mu
7810  Bitcoin / Project Development / Re: Bitcointalk Account price estimator on: January 09, 2016, 05:43:44 PM
The issue should be fixed now. All previous tokens will no longer work since the server had to be shutdown.

There have also been some additional features added. There is now a merchant feature which will give you slightly obfuscated details which is good for sellers to share with their buyers. Also requests will now be kept for 1 week after they complete instead of 1 day. There are also now (semi)permalinks to the requests so that you can share that link with others.
7811  Bitcoin / Project Development / Re: Bitcointalk Account price estimator on: January 09, 2016, 05:02:53 PM
Sorry guys, it looks like something in the program broke so it isn't working atm. I will be trying to fix it. The site will be going down shortly.
7812  Bitcoin / Development & Technical Discussion / Re: What good is a "network only" Node? on: January 09, 2016, 04:56:20 PM
Everyone connected to that full node with an SPV wallet is trusting that node. They are trusting that that node is giving the correct information.

Yes I don't dispute this. But what is unclear is if adding additional "network only" nodes (is "relay nodes" a better term?) improves that situation.

For example how do SPV wallets determine what nodes they get information from? Do they always connect to the same one? Is it random and they get messages from many nodes (from the whole network??)? If they get messages from many nodes then having more network nodes (and assuming the majority are honest nodes) somewhat increases the security of SPV wallets.

If you have more info on how SPV wallets get their info (typically from one node or whole network?) then that might help. I'm not that familiar with SPV wallet protocol.
It depends on the SPV wallet as they use different methods of getting their data. Most of them will connect directly to nodes just as a normal full node does, except they don't relay, store, or validate blocks and transactions. These nodes will connect to the network like a full node, so their connections are not always the same and having a diversity of nodes makes it more secure as it is less likely that all of its connections are colluding to provide false information.
7813  Bitcoin / Development & Technical Discussion / Re: ECKey.ECDSASignature creation on: January 09, 2016, 04:50:58 PM
When you are signing something, there must always be a message to sign, otherwise nothing is being signed. Part of signing a message is also revealing the message you signed; a standalone signature is useless since the actual message of a standalone signature cannot be known.. You should not sign your private key since that would reveal your private key in the message or simply produce a signature that you can't do anything with since you don't want to reveal the message.

You can sign whatever you want, but in the case of Bitcoin, the thing that is signed is the entire transaction. An unsigned transaction is created and something (I don't remember what) is put in place of where the signature would be and that is signed in order to create the signed transaction.
7814  Bitcoin / Development & Technical Discussion / Re: What good is a "network only" Node? on: January 09, 2016, 12:07:19 AM
Quote from: knightdk
..spreading around bad blocks and invalid transactions

But any full node (mining, wallet node) then would reject it.
Not if those full nodes were running software that was not in line with the consensus of all of the users. Those node operators could be in consensus, but they may not be in consensus with users, so they could force Bitcoin to go in one direction and any SPV wallet users (pretty much everyone else) would have to follow or start running their own full nodes.

Anyway I don't really doubt you are correct. This has always been my assumption and part of why I run a full network node myself. However I see things like https://twitter.com/adam3us/status/683678942398644224 and it makes me wonder (note: vps nodes worth zero), whether my assumption is flawed.
The problem with VPS nodes is that they aren't all that decentralized. With nodes in homes, it spreads out the node distribution. On the other hand, VPS nodes are hosted in data centers. If something were to happen to a data center, all of the nodes there would go out at once. This is about as useful as one node since there is essentially one point of failure for many nodes. Those nodes are also susceptible to the actual server owners taking them down.

Maybe you could point me to some more info on how the checkpoints and forking issues you mentioned. Have there been any simulations done for this, or detailed write-ups on the exploits?
No, I don't have any info on those issues. Basically if enough nodes ran a certain software that used certain checkpoints, then they could fork the blockchain and force a shorter chain to continue to grow. It would ignore the longest chain rule. Should both chains continue to survive, there could be some very problematic issues that arise, including double spends and long confirmation times. In the case of a fork, it may not be good to assume that a confirmed transaction is truly non-reversible.

On the one hand, yes it seems fairly obvious that full nodes improve security. On the other hand if everyone with a wallet is already directly connected to a full node, then it is less clear how the exploits progress.
Everyone connected to that full node with an SPV wallet is trusting that node. They are trusting that that node is giving the correct information. That one full node could, in theory, change its consensus rules and force everyone relying on it onto an alternate blockchain that that person controls and can do whatever he wants with.
7815  Bitcoin / Development & Technical Discussion / Re: What good is a "network only" Node? on: January 08, 2016, 11:14:46 PM
Lots of people are running full nodes that are not used for mining, not using a bitcoin core wallet with it, and not using an SPV wallet linked directly to that node. In other words it is a network node (is there another name for this?) that validates transactions and validates blocks, and interacts with other network and non-network nodes.

Are these needed? How do they improve overall security of bitcoin?  I'm really asking here, not really sure one way or the other what effect they have.
Those nodes further verify and validate transactions and blocks. It reduces the likelihood of a few people colluding and spreading around bad blocks and invalid transactions. Also, they do verifying and validating of the blocks that miners produce since a lot of miners don't actually run full nodes, they use SPV mining which does not validate the blocks. Supposedly SPV mining is faster and reduces orphan blocks.

If we had no network nodes and only mining nodes and nodes directly connected to wallets would bitcoin be less safe, more safe or the same? Like we might end up with just 100 nodes or something (1 for each large mining pool, a few for the large bitcoin service providers like coinbase, etc, and a bunch for people using their nodes with the bitcoin core wallet, and a handful of SPV users. Maybe 100 is a bit too small a number (what would the number be?).
It would be less safe. Less nodes means that a few individuals could collude and force the blockchain to go in a certain manner. They could introduce checkpoints that essentially fork the blockchain, and SPV nodes would have to follow them and trust that they are correct, even though they may not be. More nodes reduces the likelihood of that. More nodes are also a lot harder to DDoS. If an attacker were to DDoS a network with only a few nodes, he could do a lot of damage and essentially shut the whole thing down. With more nodes spread out over the earth, it becomes much harder to do that. More nodes everywhere also prevents governments from being able to seize nodes and shutdown the network as they will be people operating nodes outside of those governments jurisdictions.
7816  Bitcoin / Bitcoin Technical Support / Re: Please Help on: January 08, 2016, 08:40:12 PM
I can't even run a antivirus they have full control of the computer
Then just format the hard drive and reinstall your OS. Since you are trying to delete your private keys anyways, that will take care of that for you.

Pywallet will do this, i'm at the library i can't do it here

https://bitcointalk.org/index.php?topic=34028.0

thats the adress for it

heres the instructions

Installation:

    Linux/OSX: See README file
    Windows:
        Download https[Suspicious link removed] (SHA256: 645a4d092733ad6685de730a38b210c6594e44a15690a87a231859477deca316)
        Run it
        Click about a thousand times on Yes/Next/I Agree/OK
        Go to the directory where you extracted it and run pywallet.bat
        http://localhost:8989


How to run it:
 Download it there: https://github.com/jackjack-jj/pywallet
 Run './pywallet.py --web' then open 'http://localhost:8989' in your brower


if someone would help me i'd relaly apprciate it
You can't run pywallet without python, which you said you don't have:
I don't have python if anyone can help.

Why are you even trying to delete your private keys? How will that help you at all?
7817  Bitcoin / Bitcoin Technical Support / Re: Please Help on: January 08, 2016, 08:28:15 PM
It is disconnected, the virus is a one time package that was installed and continues to run, i unplugged modem and removed memory card and files were still being added
If you have another computer, get an offline installer of an antivirus software and save that to a flash drive. Then install it on the infected computer and remove the virus.
7818  Bitcoin / Bitcoin Technical Support / Re: watch new Tx in mempool (testnet) on: January 08, 2016, 08:26:54 PM
UPDATE: no answer ?
I do not think there is any way to do this. Bitcoin Core has a few notification things that it can do but not for every new transaction you receive. You can have it for every new block and transaction relevant to you (so not when a new transaction is added to the mempool). You could modify the source code and add that function in yourself though.
7819  Bitcoin / Bitcoin Technical Support / Re: Please Help on: January 08, 2016, 08:15:45 PM
What is the company and the tumbling service? How do you know that they hacked your computer? Did you download a virus or something from them? How will they be able to "pin" the scam on you? If you still have the private keys then you can be the good guy and take the coins and send them back to the victims.

If they have installed programs on your computer then you have a virus. Get an antivirus software and remove it. Also, when you aren't using the computer, shut it down so that they can't do anything. If you need to computer on but not online, disconnect it from the internet.
7820  Bitcoin / Bitcoin Technical Support / Re: Running latest core but node doesn't show up on node check on: January 08, 2016, 05:23:27 PM
In order to accept incoming connections you need to configure your firewalls to allow connections to port 8333. You are still running a full node and contributing, just not as much as you could if you accept incoming connections.
