What might also be the case is that you failed to make a send-to-many bitcoin transaction.

Thanks.  I am using MultiBit which doesn't support the send-to-many.

Thanks for pointing that out. I haven't actually used any other bitcoin wallet than Bitcoin-core and Electrum. However, now that I know some wallets haven't implemented multisend I must raise the priority of getting automated message writing implemented soon. The latter would allow you to write a message by making a transaction with a single output to our to-be-developed message encoder which would in turn make the real multi-output transaction for you. The drawback of such a payment proxy would be waiting for confirmations.
1502  Alternate cryptocurrencies / Service Announcements (Altcoins) / Re: CryptoGraffiti - Block Chain Message Encoder & Decoder on: October 24, 2014, 05:02:11 PM
The service is free?  Or 5500 Satoshi's per message block?

For locating the messages, do you search for your Bitcoin address?  Or is it a pre-pended identifier in the Blockchain?

Have you considered approaching Google to index the Blockchain?

Service is free. It is currently hardcoded to the user interface to have 5500 satoshis per output address as it was the minimum amount some time ago. However, right now the Bitcoin-core wallet lets you send 1500 satoshis to a single output at minimum. The CryptoGraffiti decoder does not care about the number of satoshis sent to an address, all it cares about is whether the address contains human readable text or not.

edit 2:
I locate messages by attempting to decode every BTC transaction that has been included in a new block. If I find any human readable text then I will store the transaction hash as a pointer to an "interesting" transaction. I haven't approached Google.

Two questions:
1. The date/time stamp on the latest messages on your site shows 2014/09/24.  It is 10/24.  Is this a programming typo?

2. If instant is selected, how long does it take for it to show on your website (assuming Blockchain.info shows the transaction)?

1. This is a typo that will be fixed in the next release.
2. Under normal conditions the message should show on CryptoGraffiti.info instantly (3-10 seconds). Heavy load or network lag could cause it to take longer.

Answer to #2 is after 1 confirmation.
Wrong, when instant is selected it will appear on CryptoGraffiti.info in 3-10 seconds.
edit: However, due to the bug in the current UI you would need to refresh the page yourself though.

New question:
I posted a message to the blockchain and it broke it into 4 separate messages.  Why?

CryptoGraffiti.info considers 1 message to be encoded in a single bitcoin transaction. If you're using some other message writing service then it can happen that a single message gets written into multiple bitcoin transactions. Such messages cannot be intuitively extracted because there is no known standard to determine the order of those messages.

What might also be the case is that you failed to make a send-to-many bitcoin transaction.

First of all, I admit I was a bit overreacting myself. While Bitstamp is overreacting because they are afraid for their own butt I am overreacting because I am afraid they will make me go through the verification process AGAIN. And guess what, they did:

Dear XXXXX,

While we understand that this comes as an inconvenience, we believe that our security precautions are in accordance with your expectations in keeping your account secure.

To re-enable virtual withdrawals for your account, we kindly ask you to provide a high quality photo of your ID document with a hand written note of when the image was submitted following the example bellow:

"[date of submission] For Bitstamp Limited Only"

Please note that the ID and hand written note must be submitted as one image.

We kindly ask you to attach your image in a reply to this ticket, so we can proceed with your request.

We also kindly ask you to confirm that your system and email account are not compromised.

If you wish to change your email address, please tell us your current and your new address, so we can proceed with your request.

Also be advised that 2FA is not required or forced, however it is highly recommended, as it provides an extra layer of security for your Bitstamp account. Should we ever decide to support any other 2FA, we will make sure to let our customers know.

Should you have any additional questions, please feel free to ask.

Best regards,
Nejc Srečnik

Quote from: My answer
Here's the thing:
1. I myself submitted the password recovery form to test out the functionality.
2. My e-mail was never compromised.
3. I did not lose my password.

You overreacted:
1. You disabled my withdraws without any reason.
2. You require me to go through the verification process AGAIN.

Here's my stance:
1. I will not go to bank again to get another paper copy of my proof of residency. It's your problem not mine.
2. You have to provide me a solution that does not include me going physically to the bank again!

We live in the era of digital signatures. I have an ID-card that allows me to sign documents digitally. A compromise solution would be if you accepted a digitally signed document proving that this account belongs to me. Please understand that many people don't receive paper bills and don't have a scanner to scan physical world documents. To require me to go through this painful verification process again costs you 20 euros. Send me 20 euros worth of bitcoins to 1******************************* and I will verify my account again because that's how much my time costs. I have to go to bank (40 minutes and scan in the documents 20 minutes). 1 hour of my time costs exactly 20 euros.

By the way, your security precautions suffer a serious retardation and I would seriosuly doubt if people who designed your system's security were competent enough for the job. You cannot make a user's e-mail so critical for their access to Bitstamp because e-mails are not held in secret. A malicious person would gather the e-mails of your customers and made a bot that would submit password recovery for all of your customers. Your system is flawed as it allows an anonymous user to disrupt your whole userbase's access to the service. Thus, it is you that needs to change their system to solve this problem. I am free to change my e-mail at my free will at any time I want and you cannot demand account verification each time.


To reply to other posts in this thread:
I will not start using 2FA authentication because I dislike google and Google Authentication. You better think some other way to enable 2 factor authentication if you want to force it to your customers.

Ignoring the rest of the post, but this is a bit inaccurate. The "Google Authenticator" uses a very common open-source algorithm....

Thanks for the tip. I really did not know that but now I will look the specifics of Google Authenticator. Perhaps I could still use it even though I don't like Google.

just wait and see what happens when you hit some (invisible) volume limits with fiat deposits and withdrawals...

got my assets frozen for a week and a half while I was travelling europe. awsome experience.

but to get back to OPs issue:

They are simply scared shitless, that someone might actually steal customer funds so they are overshooting a "bit".

bitcoin.de is a great place, but it is a market place, not an exchange so that comes with its own set of issues (forget trading apis and other fancy stuff).

Exactly, that's what I'm afraid of. Once I start moving big money they might make my life miserable as they obviosuly do not care for their customers' convenience and user experience at all! Too bad bitcoin.de is not an exchange though, I was really hoping that there is some exchange in Europe that makes the verification process super easy. Come on, we have ID cards that allow signing documents digitally. Verification could be so simple yet they are stuck in the archaic way of doing things by requiring photos of physical world objects!

I guess there is a problem with stamp's database or capital chain, so they are so anxious to clean up the accounts, wish it not to be gox 2.



edit: about bitcoin.de, its verification seem to be the same hard: if you're not German, you have to send them all kinds of documents to be able to buy/sell for more than 750 eur a year.

according to https://bitcointalk.org/index.php?topic=695082.0 , LakeBTC and Kraken both have sepa account, while them also need to verify, but it will be a lot easier, you can try.

Isn't Kraken like on the other side of the planet? I'd prefere an EU exchange but if you say LakeBTC and Kraken would work then I will definitely check them out, thank you!

Just a measure to protect the customers from themselves.

It is way better than having all your coins stolen.

I guess it's free market. You can say that it's for the customers' own good but the fact is that their security measures are inconvenient, archaic and could be done much better. People will soon simply go to other exchanges. Facebook has automatic SMS sending to improve account security. Why doesn't Bitstamp have one? I would happily receive a SMS to my mobile phone with a pin.

I will never ever use Bitstamp. But on the other hand you shouldnt have made it complicated. Youre account was ok, why did you try the password recovery? You shouldve crossed the bridge when you get there.. You shoudve tried the password recovery if you really need it.

I requested the password recovery because I did not know what e-mail belonged to what account in Bitstamp. I had 3 accounts in Bitstamp and 3 different e-mails for them as this idiotic Bitstamp does not let you register 2 accounts for the same e-mail. So I requested password reset to know which account is which. Never before I have seen a system so moronic that instead of resetting your password it creates a new account for your e-mail and requires you to go through the painful verification process again. This could be abused so bad. I could just datamine all the e-mail addresses used in the bitcointalk forum and reset everyone's password in Bitstamp and everyone would need to verify their account AGAIN. It is clearly Bitstamp's idiocy here and it has nothing to do with security precautions. From this moment I seriously distrust Bitstamp. If they make such mistakes who knows what other mistakes they have made!

This verification process is annoying I agree, but they are forced to do so.

At this point people are complaining about it's way too difficults, too much hassle....

But if they don't, and one day lose a lot btc due to a hack or fraud, then people will complain and moan about why they don't have a proper verification process.

Rules are rules, if you prefer to have an exchange with less rules, then I suggest BTC-E.

While I get your point you are wrong at one thing: users don't need to suffer due to lazy programming and bad business workflows. Does PayPal require users to verify their account like that? Scanning in some papers and so on? I doubt it. See, it can be done more easily so why hasn't Bitstamp come up with a better solution? Or perhaps they don't have enough money for these developments. The biggest exchange does not have enough money? Suspicious.
1504  Economy / Service Discussion / Re: Bitstamp is bullying VERIFIED CUSTOMERS! on: October 21, 2014, 05:06:20 PM
...

From the beginning I had problems because I had several accounts in Bitstamp due to the need to use their API in a separate account.

...

lol.

Why is that funny? It's best to use a different account for automated trading because if your bot screws something up you don't want to lose more than you can afford to lose, do you?

kindly suggest

which means you don't have to change anything, bro.

Yes, and I won't. However, how come some random customer support dude can stop my withdraws without asking my permission or anything? I've been wanting to change my e-mail for a year because I registered with a throwaway e-mail address and now they won't let me change the e-mail and I have to use it just to please Bitstamp. What a mess.
1505  Economy / Service Discussion / Bitstamp is bullying VERIFIED CUSTOMERS! on: October 21, 2014, 01:22:20 PM
I went through the painful process of getting my account verified a year ago. It included going physically to bank to get a proof of residency paper printed out and signed on paper (in the era of digital signatures provided by the ID-card in EU, hilarious). Not only that, I had to scan in my driver's license and that proof of residency and submit it to Bitstamp and they rejected it due to poor quality! So I scanned the documents in again with higher resolution and got finally verified.

From the beginning I had problems because I had several accounts in Bitstamp due to the need to use their API in a separate account. These idiots demand different e-mail for different accounts and to make matters worse YOU CAN NEVER CHANGE YOUR E-MAIL. If you do, they require verification AGAIN. Unbelievable. But that's not the end of it.

I tested out their password recovery mechanism and entered my e-mail in the according form. I received a message from Bitstamp saying that a new account was created for me. What the hell? They create a new account when you request password recovery! Anyone who knows your e-mail can make a new account under your name and that new account is NOT VERIFIED by default.

So I got worried that they might force me to go physically to bank again just to get a piece of paper and I contacted the support and it made things even worse as they disabled my account's withdraw capabilities:
Quote from: My initial support ticket
Someone requested my account password to be reset (they must have known my e-mail address) so I received an e-mail with new login information to my e-mail. Can I just ignore it and keep using my current account as if nothing happened? I logged in once with the given login information and saw that the new account is not even verified.

Dear XXXXX,

Thank you for notifying us.

Since you did not request password change yourself, we kindly suggest you change your email address linked to this Bitstamp account as a security precaution. Please note that additional KYC will be required should you decide to do so.

We highly recommend you enable two-factor authentication for your account. You can do that here: https://www.bitstamp.net/account/security/two-factor-authentication/ ;and help yourself with our step-by-step 2FA setup guide: https://www.bitstamp.net/s/documents/bitstamp_2_factor_authentication_guide.pdf .

Please be advised that we have also blocked virtual withdrawals for this Bitstamp account as an additional security precaution. Once you are convinced that your system is clean and you decide to unblock withdrawals, please tell us so in a reply to this ticket, so we can proceed with your request.

While we appreciate that this comes as an inconvenience we are convinced that our security precautions are in accordance with your expectations in keeping your account secure.

Should you require additional assistance, please feel free to contact us again.

Best regards,
Nejc Srečnik

So here's my reply:
Quote
What additional KYC you need when I decide to change my e-mail? I am not going to bank again just to get another proof of residency paper in order to change my e-mail.

I will not start using 2FA authentication because I dislike google and Google Authentication. You better think some other way to enable 2 factor authentication if you want to force it to your customers.

Also, I'm utterly displeased by the fact that you have blocked virtual withdraws. Why did you do that? Did I give you any permission? Your security precautions are unreasonable. A customer should be able to change their e-mail as they wish.

So here's what I ask you to do: make my account fully functional again. I cannot trust you with my money if you suddenly decide to stop withdraws so randomly.

This has gone too far. I did the painful verification process, went physically to bank just to get that proof of residency as I am not receiving any paper bills. What is more, I had to scan in my driver's license and that proof of residency and after all of that you are stopping my account because someone used my e-mail to reset my password? It is you and your business that is dysfunctional and I demand an apology.


So clearly Bitstamp is getting worse and worse over time. Just painful user experience. What other businesses offer bitcoin exchange services in Europe? (Preferrably not shady)

edit:
So I found out about https://www.bitcoin.de/en they seem to have automated verification so I'd suggest I don't need to scan in any documents, I think it's great! Also, I still cannot believe that Bitstamp morons require the user to change their e-mail address. An e-mail address is not a thing anyone would easily change. God it makes me vomit to see how stupid the Bitstamp developers are. Do you imagine if all the web services started demanding from their customers to CHANGE THEIR E-MAIL ADDRESS?! Bitstamp shold be sued for such idiocy.

CannabisCoin? no way, how on earth would that be a viable investment? What problem does it solve? Most people even don't give a shit about cannabis. I personally strongly dislike cannabis and I think it's way overrated. I'd rather see DMTCoin or AyahuascaCoin but even those ideas suck. TBH I thought you were talking about NuBits or Peercoin which I believe will surprise us all in the near future. For instance, NuBits has been live for a month now and it's the most stable cryptocurrency ever released, trading perfectly 1$ each.

Cool to see people getting ripped of by HYIPs still in 2014. Brings back bad memories of my childhood when I invested my hard earned pocket money into HYIPs like SolidInvestment and FastMarket using e-gold Cheesy I was 16 years old (2004) and lost 300$. It's interesting that when I initially bought bitcoins I never saw it as a ponzi, quite the opposite.

It is currently really difficult to find one's graffitis after a while. I propose a search function for btc address or transaction, or maybe even part of the text of the graffiti!

Thank you for your idea. We have these features in our TODO list but at the moment we are working on a new framework which is a prerequisite for all these advanced use cases.

I made a mistake with this BTC's prediction. I had some information that turned out to be invalid. The main stress on this prediction went on PPC though, and luckily that wasn't invalid. I still consider PPC highly potential in the coming months. BTC not so much anymore.

I'm also very bullish on Peercoin. Care to share your knowledge about what big things are coming to PPC in the coming months?

1515  Bitcoin / Project Development / [ANN] CryptoGraffiti.info now available over TELNET! on: October 13, 2014, 09:23:40 PM
That's right, I just finished a three day coding marathon and our telnet server went live. The CryptoGraffiti Decoding services provided at http://cryptograffiti.info are now also available over the telnet protocol. Just connect with PuTTY if you're using Windows or type telnet carlnet.ee 4000 in terminal if you're using some *NIX.



I developed this telnet service because I used to be a MUD implementor when I was younger and I still like the old school experience that telnet protocol has to offer. Whenever someone writes human readable text in the block chain the telnet service notifies its connected clients in real time.

At the moment the functionality is rather elementary but over time I might add new features. Let me know if you have any cool ideas what to add to the service.

Known issues:
* the archived messages are currently ordered totally randomly

edit:
As of October 2017 I have disabled this service due to Bitcoin Core getting corrupt and going rogue. Bitcoin Cash is now the real Bitcoin.
1516  Alternate cryptocurrencies / Service Announcements (Altcoins) / Re: CryptoGraffiti - Block Chain Message Encoder & Decoder on: October 13, 2014, 10:48:21 AM
Of course, but perhaps we can replace old pointers to transactions in the blockchain with new pointers.

For example, I write a graffiti "I Love Lucy." Then I stop loving Lucy and start loving Linda. I make a new graffiti "I Love Linda" and replace the old "I Love..." graffiti with the new one (in CryptoGraffiti, not the blockchain).

That's a nice idea, thank you! I could implement a possibility for the message's creator to remove the message from my database. The message will still be in the block chain but my service would not display it any more. The process would require the user to prove ownership over one of the input addresses that were used to make the transaction. The latter is easily done with the signature functionality that comes with Bitcoin's private keys.
1517  Alternate cryptocurrencies / Service Announcements (Altcoins) / Re: CryptoGraffiti - Block Chain Message Encoder & Decoder on: October 12, 2014, 11:58:53 AM
What exactly is the format used for encoding? ASCII encoded in base58 format (minus the version, and the checksum)?

Bitcoin address in its raw format contains 20 bytes of data. These 20 bytes are later converted into base58 and a checksum is appended, thus we get a typical bitcoin receiving address. To decode an address I restore the underlying 20 bytes from the bitcoin address and seek common ASCII characters from it. If more than 90% of the characters are visible ASCII characters then the address is assumed to be human constructed and thus is probably a human readable text.
1518  Alternate cryptocurrencies / Service Announcements (Altcoins) / Re: CryptoGraffiti - Block Chain Message Encoder & Decoder on: October 12, 2014, 11:10:13 AM
Very cool! Is this a Twitter on the blockchain? Are there possible ways to permit editing messages already sent?

You cannot edit anything that has been saved in the block chain unless you control more than 50% of the network's hashing power.

Huh? Bitcoin-qt has had *coin-control* for a long time now.

Ok it has, just had to enable it. Anyway, I did not immediately see a possibility to permanently lock some address so that its funds would never be consumed by any transaction.

Anyway - you can use pywallet to delete keys from your wallet (take a backup of your wallet first of course).

That's what I feared. At least an RPC call should be available for deleting a private keys.
1520  Bitcoin / Bitcoin Technical Support / Delete private key from wallet on: October 11, 2014, 01:02:15 PM
So here's my problem. I imported a private key that receives donations to my personal hot wallet. I am not allowed to spend money on that donations address but it is now stuck in my hot wallet! How can I remove the imported private key from my hot wallet? It renders my whole wallet useless because Bitcoin-core lacks coin control and whenever I try to spend money from my hot wallet the donations might also be used up in transactions.
