I sent some bitcoin to the addres given, after which my chrome crashed. I don't see my message on the "Read" tab, is something wrong? Will my transaction bounce back?

It seems to me that you have sent a wrong number of bitcoins. You have sent 0.00121560 BTC (57c2e3bc92113ef5998f75f1a63d27c335a697fa07514ecbf9f23a005e73895f) but you were asked to send 0.00152156 BTC. Do you know why did you send the wrong number of coins? Was it a typo?

Version 0.71 has been published.

Enhancements to the graphical style of the new user interface...





As hinted on the second screenshot, I am already working on the file saving functionality. You can soon upload the picture of your cat on the bitcoin's block chain using cryptograffiti.info.

The first release version of the new user interface is now available at http://cryptograffiti.info



The old version is still available here: http://cryptograffiti.info/old.php

@odotan

I just uploaded v0.6 of cryptograffiti reloaded and your Hebrew message is now displayed correctly:
http://cryptograffiti.info/interface/reloaded/index.html#4106
(right to left direction is now effective).

v0.6 introduces bug fixes regarding selection of long messages. selecting between 2 long messages by their body is no longer buggy (before it deselected the wrong message sometimes). Also, content is now vertically centred in all tabs. UTF8 messages are now properly decoded in cases where a multi-byte utf8 character occupies 2 sequential bitcoin addresses.

This is a very powerful idea. And it keeps messages secure, encrypted and small in length. I do really appreciate you have put lot of efforts in developing the tool. However, a long time awaiting for you to reach more people. Keep going with this great idea.

thanks for the support,  I really appreciate such posts unlike others who accuse me of filling the block chain up with garbage  Grin.

Do you think we could manage to put the entire book with similar fees/dust size? We're talking about this text:

https://www.dropbox.com/s/bvka8swl4z3nkat/Torah.txt

It's about 750000 characters, 1406852 bytes... so should be about 70000 addresses

The text is 1.4 MiB large. Bitcoin has maximum block size of 1 MiB currently. It is technically impossible to save such a large file in the block chain as a once chunk. I compressed the text as a zip file and it reduced its size down to 296 KiB which is approximately 15000 output addresses. Whith 2700 satoshis per output address it would cost 0.4 bitcoins just for the outputs, but transaction fee would be added to it.

148 * number_of_inputs + 34 * number_of_outputs + 10
would be
148 * 1 + 34 * 15000 + 10 = 510158 bytes = ~ 500 KiB transaction size
The amount charged per 1000 bytes defaults to 0.0001 XBT
So the miners would require 0,0510158 bitcoins as a transaction fee for such a transaction.

Apparently transactions larger than 100 KiB are non-standard anyway, so we would have to find a miner that is willing to confirm the transaction. Some mining pools accept non-standard transactions and thus we could potentially reduce the cost of a single output down to zero, but the miner will probably require a higher fee.

I say about because the write page became unresponsive when I tried to paste the entire text, so I pasted about 1/10th of the text and got this:

Chars: 75658
Bytes: 143557
Addresses: 7179
Cost: 0.04009188

This calculation is not accurate since the dust threshold has been increased 5 times and paystamper is probably still using the old threshold.

So the whole book should be about 0.4 btc.

Is there something that you can do about the page unresponsive, or maybe an upload button, so I can upload the file?

Also, is there some kind of optimization we can do for the costs?

Can we still send one satoshi dust such as here

https://blockchain.info/tx/e0ce23d299bb1b7decdf86522c023554bbdeab80cebcca6aa09f01a86c65d10e

or would this not work anymore?

How many addresses could we fit into one transaction, what dust, and what fees should we use?

Thanks again very much for the quick and thorough response.

I am planning to develop file uploading possibility for cryptograffiti but it will take some time.

So here are the options:
compress the book as a zstream or as a zip file and upload it as a one large transaction
or split the book into multiple parts and upload each of them as plaintext.

Since I am planning to develop zip file and zstream decoding anyway, I would suggest going for the compression and hoping that some miner will accept a 500 KiB transaction Cheesy

Good news, some miner finally decided to confirm the transactions. Your message is now saved in the block chain.

By the way, I have been working on the new version of cryptograffiti for quite some time now. I will start working on the write tab in the near future and I plan to make automated message encoding more user friendly. For example, the users should have the possibility to include their chargeback address so that in case of problems it would be easier for me to send them back their bitcoins. Also, I will have to upload the raw transaction hex in addition to the transaction hash so that the user could immediately verify that their order has been filled indeed and even broadcast the transaction manually if needed.

This new work in progress cryptograffiti is available here:
http://cryptograffiti.info/interface/reloaded/index.html

When I get it done I will replace the original cryptograffiti.info with the new version.

Thanks very much. To answer your question from the previous response, I did not send the other transaction you mention.

The text I posted is the beginning of the book of genesis in Hebrew. It's part of an experiment to put the whole old testament on the blockchain

Thank you for contacting me on the matter. I just noticed that there are problems with your transactions. Turns out that blockchain.info has gone nazi with dust transactions, so it won't even accept transactions that don't meet their criteria. I'm afraid too many nodes have increased their dust threshold above what cryptograffiti is currently using. Your order was indeed filled and the related transaction was sent to the network but hasn't been confirmed for some time now. I have increased the minimum transaction output for the cryptograffiti service to 2730 satoshis so hopefully future orders will be confirmed fast.

In case you know some mining pools or miners personally, you can always ask them to confirm the following 2 transactions, so that your message(s) would be saved in the block chain:

I have already rebroadcasted these transactions in all the services listed here:
https://en.bitcoin.it/wiki/Transaction_broadcasting

But you can also try these and perhaps you know some other services willing to broadcast these transactions. If the transactions remain unconfirmed until Friday I will send you your money back on Friday.

Did you only make transaction cd6ad0c3bb98df7d221707a27e61b0d4f520555b0258eb7a24dd6c64166a7774 (0.00859924 BTC) or the other transaction as well that is still not confirmed?

The main purpose of CryptoGraffiti.info is to display transactions which include addresses that have human readable characters in them.
how do your algorithm knows if a transaction has "human readable characters"? Do you use a header or something like that?

I convert all TX output addresses into raw bytes (1 address contains 20 bytes of data).

First, I scan each of those 20-byte chunks for human readable ASCII characters. If more than 90% of the bytes are visible ASCII characters then the output is considered meaningful and the TX hash will be uploaded to cryprtograffiti's database.

Then, I scan each of the 20-byte chunks for valid UTF-8 characters to also detect UTF-8 strings encoded in the TX outputs. This UTF-8 detection is far more complicated than ASCII detection. If any of you is interested of the exact algorithm I can paste you the Lua and C++ code I use for that.

Finally, I scan the TX outputs for a JPEG header and some other JPEG image specific data to determine whether the TX contains a JPEG image.

If the TX is detected to be either ASCII, UTF8 or JPG then its hash will be uploaded to cryptograffiti's database. Although I have not officially published cryptograffiti's API, you can experiment with the public API functions if you wish:
http://www.cryptograffiti.info/API (ignore the initialize and security handshake functions, they are not necessary for you).

Sometimes I see some andresses marked in red color, what does it mean?


The red colour indicates a duplicate output address. The standard bitcoin-core client does not allow you to make a TX that contains duplicate output addresses. However, the bitcoin protocol itself allows duplicate output addresses. If you intend to save your message in the block chain with bitcoin-core wallet, then you must get rid of duplicate addresses by modifying the text. If you intend to use "import to paystamper" functionality then you can ignore the red addresses since paystamper compiles, signs and propagates the TX manually, allowing it to contain duplicate outputs.

The ability to mark words on a digital chain of data, forever, is truly something to think about. What a time to be alive.

why not allow unique trx only and use a filtering mechanism that blocks messages with target words such as:

Seems that BTCChina released their own encoding service to write messages in the blockchain. Are you guys also behind it?

BTCChina Press Release: http://www.coindesk.com/press-releases/btcchina-releases-blockchain-inscribing-service/

They are encoding messages into coinbase which is what only miners can do. Currently cryptograffiti doesn't even attempt to decode coinbase messages because miners put their names and some other meaningless spam into it. Perhaps in the future, if we figure out how to avoid spam in coinbase, we would start monitoring the coinsbase messages too. Or perhaps the coinbase messages should have a slightly different monitoring mechanism that is more spam tolerant. I will have to think about it. I think it's a good idea to also start monitoring coinbase messages with cryptograffiti even though regular users wouldn't be able to save such messages.
