341  Other / Beginners & Help / Re: Need a Linux Bitcoin Developer, setup Wallet + API Block.io on: June 13, 2016, 07:15:37 AM
I'm a bit confused here... You're running a webshop, you want a wallet on your VPS (i can only assume you want a full node), you still want to use block.io, you want an address shown at your thank you page, but it has to be a new address every time sombody visits the page?

My questions:
- if you want a local wallet, why would you still use the block.io API... Why not use the local bitcoind via json-rpc?
- why would you want to show a new address on your thank you page... I can only assume it's a donation-page, so the address doesn't need to be unique.  Or do you want your customers to be able to pay with BTC, in that case i'd go for coinpayments.


I can only assume the last part: you want your customers to be able to pay with bitcoin. In that case i'd forget about installing a full node, block.io,... I'd visit coinpayments.net (or a similar processor), they have a truckload of documentation on how to integrate their payment processor in webshops.

Dont know will takes how long the transaction will get confirm or will get rejected.


If you're asking us how long it will take for the transaction to be added to a block: nobody knows... It can happen 10 seconds from now, or it can take several days (or more).
It's all pure luck. A miner decides which transactions he'll put in the block he's mining. He might chose your transaction, or he might chose somebody else's... A lot of times, miners chose the transactions with the highest fee per byte, some of them do make exceptions tough. Maybe one of the pool operators takes pitty and adds your transaction out of kindness, you never know Wink

Good luck!
344  Bitcoin / Bitcoin Technical Support / Re: please help.. i will give a reward.. my transaction is unconfirmed for 2 days. on: June 09, 2016, 07:57:53 AM

Any idea to do the suggestion you give?
"Another method is to request a mining pool to mine it for you if the first 2 doesn't work out."

So you mean the transaction will be keep on network and will not rejected?


I suppose what ranochingo is saying is: you could contact a couple big mining pool operators, and offer them a bounty to include your transaction in the next block they mine.
I've seen this proposition many times before, but i cannot remember if somebody suggested which pool operator was open to such offers.

A miner can chose which transaction he'll include in the block he's mining, so this tip does makes sense if you find a big pool operator willing to help you out.
345  Bitcoin / Bitcoin Technical Support / Re: please help.. i will give a reward.. my transaction is unconfirmed for 2 days. on: June 09, 2016, 06:17:52 AM
lucky i havent upgrade my wallet become beta version.
so i may able to follow the step that given to get the  private key.
but after get the private key, any steps to get the transaction done?
thank you for helping me. =)

Well... shorena has a really good point, it might be a good idear to just wait it out.
If there is urgency, i'll explain my method on how to create a double spend (spend the same input you used for fe09397d068f68fc3656d345e8e6621a3b7a1e301e50dd7884a84e42128ca6d9, so the other transactions will be cancelled, or however it's called).

This is the method i use, it works for me, it might not be the best method around, and you can basically do a lot of things wrong, so it might not be the best method for everybody!!!

- go to coinb.in, download the sourcecode to your computer, unzip, open the index.html on a computer connected to the internet
- go to new -> transaction
- enter your address, click load
- go to the inputs-tab, remove all inputs exept the input of 1.77844113BTC
- go to the outputs-tab, enter 127kYuzS1MvxNqcBUaPdPsw1RBfEKVEyND and the ammount of bitcoins you wish to send to this address
- ALSO enter your change address 1NHY2JHJUbnkhhu1ziNdcs8fhKt6HtR6WS, send (1.77844113 - the ammount you sent to 127kYuzS1MvxNqcBUaPdPsw1RBfEKVEyND  - a decent fee) back to yourself. A decent fee can be calculated by looking at the size of the transaction in bytes (you might need to do a testrun for this) and multiply it by 50 satoshi's (look here for the exact amount to multiply with: https://bitcoinfees.21.co/)
- click submit
- copy the output
- disconnect your pc from the internet
- go to the sign-tab, paste the output and your private key, click submit, copy the output to a textfile
- reboot, reopen the index.html
- open the textfile, copy the text
- go to the broadcast-tab, paste the text, click on broadcast

BEFORE YOU BROADCAST, paste the text in this thread, let us have a look at it... You can past all outputs here so we can verify DO NOT SHOW US YOUR PRIVATE KEY!!!!!!!

346  Bitcoin / Bitcoin Technical Support / Re: please help.. i will give a reward.. my transaction is unconfirmed for 2 days. on: June 09, 2016, 05:49:36 AM
yeah, i saw it.
so means the root of the problem is TX fe09397d068f68fc3656d345e8e6621a3b7a1e301e50dd7884a84e42128ca6d9 right?
so can you teach me how to create a private key and create new transaction??
thank you.. i hope you and danny can solve this.
i am really stressed..

Well, the main problem is indeed the first transaction, you've used an unconfirmed input to generate outputs three times, so tx fcaba03f4c4929c949aec9bbda7028e4414a88ad61823d675b48eb94dad2c881 afb131a031cd58a9cefb5afdc868c91534ca1afeade70e0b2d152e3cefee72fd and 8f464213ffac4a9b38b2cd1e98b22a1b1be004bf4f79f2c84fb891b560660606 cannot be confirmed before fe09397d068f68fc3656d345e8e6621a3b7a1e301e50dd7884a84e42128ca6d9  is confirmed i'm afraid.

@Dannie: you seem to be correct, it was the procedure for the "old" blockchain.info wallet... I don't use blockchain.info very often, so i didn't really follow the hype around the new wallet.
I tried searching for a tutorial on how to export keys from the beta version, but i couldn't find one i'm afraid... Maybe OP can contact blockchain.info's support and explain the situation, ask them how he can export his Pk?

One extra thing: doesn't blockchain.info stop broadcasting unconfirmed transactions after a while? In that case OP only has to wait... I'm not sure about this, maybe a blockchain.info expert can shed some light on this?

--snip--

and you said you dont know how to get the private key of blockchain? hmm i think if you cant find, not even me. since i am newbie.. =(

--snip--

I used google to find this one: https://github.com/OmniLayer/omniwallet/wiki/Exporting-Private-Key-from-Blockchain.info-and-Importing-to-Omniwallet.org
The first 9 steps should allow you to export your private key from blockchain.info... DO BE CAREFULL, do not give your private key to anybody, and make sure your pc is clean
348  Bitcoin / Bitcoin Technical Support / Re: please help.. i will give a reward.. my transaction is unconfirmed for 2 days. on: June 09, 2016, 05:31:52 AM
There's one input and two outputs, so Dannie is correct, you could use the private key for 1NHY2JHJUbnkhhu1ziNdcs8fhKt6HtR6WS to create a new transaction using the input of 1.77844113BTC to generate two outputs (one to 127kYuzS1MvxNqcBUaPdPsw1RBfEKVEyND and one to a change address). you could do this by exporting the private key, downloading the sourcecode of coinb.in and using this tool to create a new transaction. There are several other ways of doing this. You might be able to do this with electrum to (don't know).
If you need a how-to, let me know.

You do realise you used the change to create a new transaction, right?

The output of the unconfirmed tx fe09397d068f68fc3656d345e8e6621a3b7a1e301e50dd7884a84e42128ca6d9 is used as input of tx fcaba03f4c4929c949aec9bbda7028e4414a88ad61823d675b48eb94dad2c881

The output of fcaba03f4c4929c949aec9bbda7028e4414a88ad61823d675b48eb94dad2c881 is used as input of afb131a031cd58a9cefb5afdc868c91534ca1afeade70e0b2d152e3cefee72fd

350  Bitcoin / Bitcoin Technical Support / Re: Transaction sent with ZERO fee! Now seems lost :( on: June 08, 2016, 09:33:16 AM
Hi Guys,
 Sent only my second ever BTC for a payment on 06/06/16 (first was done via mntgox)

only I seem to have sent it with a ZERO fee Sad

its been a few days (during which I've been able to see the address is being used), however, this morning, apart from my wallet - I can find NO record of my transaction at all

Will the missing BTC find its way back to me, or is it lost?

Details from wallets Transaction:
Status: 0/unconfirmed
Date: 06/06/2016 04:25
To: 14c9xgzuMhL7wt24F6cJrqidaCxoh1i2ZN
Debit: -1.00019198 BTC
Net amount: -1.00019198 BTC

Anyone able to tell me whats going on please?

Thanks

Are you the sender AND the receiver?
In that case, if a transaction is forgotten by the network, it should find it's way back to you.

I am looking forward in investing in Digibyte is there any online wallet for it like Coinbase or Blockchain.
Thanks


A quick google turned up https://www.coinwallet.co/en/currency/DGB
I don't know if it's reliable, my advice would always be to stay away from online wallets (with an online wallet, you're not the only one having access to your private key, sometimes you don't have access to your private key at all, so you're not the only one in controll of your funds), but in case you do your research, and you're willing to take a big leap of faith, you now have an online wallet.
I saw coinwallet but I avoided to use it because it says " Important Notice: CoinWallet.co is closing. Please withdraw all coins by May 1st 2016. click here for the announcement "

I doubt that if I made any deposit then they might close @any moment

sorry, i missed that text at the top of the page, i just googled a bit and posted the first url that looked more or less like an online wallet Wink
I know it's not really what you asked for, but coinomi also includes digibyte (as a beta). Coinomi is an android wallet supporting multiple coins.

The pro's:
-it's an android wallet, so exactly like an online wallet, it can be used anywhere where there's wireless internet available
-the keys stay on your android device, and are never sent to the server
-it's an HD wallet, meaning you don't have to sync the full blockchain, only the headers (meaning it's fast and small)

the cons:
-you'll need an android phone
-you'll need wireless internet
-IMHO less safe than a desktop wallet (but safer than an online wallet)

353  Bitcoin / Development & Technical Discussion / Re: Guys do you have already bitcoind installed? on: June 06, 2016, 11:57:04 AM
Yeah i know it will drain my funds but its just for study purposes i will change all script once this is script is working so that i can't waste my time to make a dice in other crypto..
Thanks for your link.. but i don't like to wait to install the whole blockchain.. before i can use bitcoind..

If i'm not mistaking, this script uses json-rpc calls to the coin deamon, every altcoin that supports these calls can be used in this script...
You can use this dice script for litecoin, dogecoin,... without any adaptation.
once again: this script is compromised, so you'll probably  be better off writing your own script from scratch than digging trough somebody else's poorly written and poorly commented code in order to fix all vulnerability's.
I must say i did not fully review the code, but i took a quick glance and i'd rather write a script from scratch than clean this one up (but that's just my personal sentiment about this)
354  Bitcoin / Development & Technical Discussion / Re: Guys do you have already bitcoind installed? on: June 06, 2016, 06:02:55 AM
Guys just want to ask if theres a free test bitcoind already installed?
I need this for study purposes
This is the settings that i need

server=1
rpcuser=bitcoinrpc
rpcpassword=dfbufbSUBUSbf7763YSFYbfybsiyb87
rpcport=8332

and this is my first time to run a premade dice script but the problem don't know how to install bitcoind.. i would like to test the premade script if working so i am looking for a free bitcoind and wallet info without funds.. just to try the script if it will work..

Heres the link where i get the script https://github.com/felinegambler/CryptoDice

I hope someone can help me..

First off: this script is filled with flaws... If you use it, you'll probably lose your bankroll!!!
Secondly: to solve your problem, i would suggest installing virtualbox (it's free), linux, and follow a tutorial to install bitcoind. It's not that hard, it only takes a long time (and diskspace) to synchronise. I'd go for ubuntu 14, and try this tutorial: https://bitcoin.org/en/full-node#ubuntu-1410
Anybody with sufficient technical background should be able to do this...

You could also run an altcoin deamon with a smaller blockchain for your tests... Just don't run this one in production!
355  Bitcoin / Electrum / Re: Electrum restore try on: June 02, 2016, 09:53:28 AM
My monitor broke down, so I cannot access my PC for the moment for a few days until I buy a new one. I have the seed of electrum 2.5.4 and have the same version of the 2.5.4 installed in my laptop, I am restoring through the seed but its taking quite a while. Is this normal and is a problem to have the same wallet in 2 different PC ?
Fast answer is greatly appreciated.

Edit: Everything went perfect now.

Is it a problem to have same wallet in 2 different places ?

To answer your last question: it's not a real problem to have your wallet in 2 different places. I do this all the time (i have one wallet at home, and the same one at work), the only problem is you'll have to sync your labels once in a while (well, at least that's my experience with this).
356  Bitcoin / Hardware wallets / Re: Would you buy a hardware wallet? on: May 31, 2016, 11:44:44 AM
Hardware wallets are offline so they are safe but the most people are going for 100% security so they will not pick a hardware wallet but instead they will take a paper wallet most of the times.

I think paper wallet is dangerous wherr yoy put your money is its because if you accidentally delete your files well i think you will be broke if that happen, well i can say blockchain is the very best and ideal where to put your bitcoin and you can assure your bitcoins are quitely sleeping safely thats why many people prefer to use it because it has strong feature that even pro hacker cannot broke, and i dont really want to put my btc in some hardware wallet becausr it is not flexible and convenient to use,

I would never call blockchain.info safe, do a quick google: https://www.google.com/search?q=blockchain+account+hacked you'll see dozens of people that lost their coins that were stored on a blockchain.info wallet
A hardware wallet might not be the most flexible, but at least your coins are safe... If you google https://www.google.com/search?q=trezor+wallet+hacked you'll see a lot of people asking questions about trezor's safety, but i couldn't see a single one proving his funds got stolen from a trezor.

In the end, it's up to you... If you want an online wallet that can be used from any computer or phone that has internet connection, and you're willing to give up some of the security, that's fine (as long as you know the risks you take).
On the other hand, if you want the best protection, and you're willing to give up some flexibility, you should go for a hardware or paper wallet.

Just my tought tough.

Yes, you can check. That's surely someone you typped a bad address. What's the txID ?
Sorry, but I don't know what a txID is l. I'm new to BTCitcoin.

A fun fact is that all the addresses that were payed in the blockchain begin with '1'. Mine too.

Most addresses start with 1. A very small percentage start with 3, the rest with 1
359  Bitcoin / Electrum / Re: Is Electrum a safe wallet to keep bitcoins? on: May 30, 2016, 06:17:54 AM
Does everyone keep a cold wallet? Looks to be a lot of hassle if a person do not store a lot of coins.

I can only speak for myself, but i do have both a hardware wallet and paper wallets.
When i had just a very small ammount (like $50-$200 worth of BTC) i only had paper wallets, but after i got around 1BTC, i decided to go for a hardware wallet. It was a great investment. They start at less than 20 bucks for the cheapest one.

btw: a paper wallet isn't that much of a hassle to generate. You do have to follow the correct procedure to generate one safely. If you just open bitaddress.org on an unsecured, online computer where you've installed a lot of cracked software, run the generator while online, create an unencrypted paper wallet, print it over wifi and keep a pdf copy on your pc, you're probably better off installing core, electrum or multibit. If, on the other hand, you follow the correct procedure, paper wallets are really safe, and really cheap to make Smiley
360  Bitcoin / Electrum / Re: Is Electrum a safe wallet to keep bitcoins? on: May 29, 2016, 10:53:32 AM
Thanks! But if the electrum software gets updated, what will happen to my bitcoins? Do I have to use download the latest electrum to keep my bitcoins?

bitcoins aren't physical things... Basically, a wallet is just a piece of software to manage your private keys, generating transactions, broadcasting.
If electrum updates, nothing happens. You either chose to install the update or not (which usually goes seamingly, and if it goes wrong, you just use the seed words you wrote down when you first installed electrum, and restore your wallet... The worst thing that'll happen is the fact that you lost your labels).
If you chose to run an outdated version, you won't have access to the latest bugfixes, patches and new features, but usually,it's not a real problem.

PS: I'm also a big electrum fan. Core might be a tad bit better, since you synced and verified the full blockchain, but electrum is still good, since your private keys don't leave your computer, and can be encrypted with a strong password and 2fa
