Nelson Mandela tribute The Bitcoin blockchain contains this image of Nelson Mandela and the tribute text.

Someone encoded this data into fake addresses in Bitcoin transactions, causing it to be stored in the Bitcoin system. Nelson Mandela “I am fundamentally an optimist. Whether that comes from nature or nurture, I cannot say. There were many dark moments when my faith in humanity was sorely tested, but I would not and could not give myself up to despair. That way lays defeat and death. The brave man is not he who does not feel afraid, but he who conquers that fear.

No axe is sharp enough to cut the soul of a sinner who keeps on trying, one armed with the hope that he will rise even in the end. Below is an excerpt of one of the transactions storing the Mandela information. If you convert those hex bytes to Unicode, you get the string 3Nelson-Mandela. Similarly, the following addresses encode the data for the image.

Thus, text, images, and other content can be stored in Bitcoin by using the right fake addresses. The Bitcoin logo, hidden in the blockchain. Prayers from miners Early on, the miner Eligius started putting Catholic prayers in English and Latin in the coinbase field of blocks they mined.

Here are some samples: Benedictus Sanguis eius pretiosissimus. Benedictus Iesus in sanctissimo altaris Sacramento. Ave Maria, gratia plena, Dominus tecum. Benedicta tu in mulieribus, O Heart of Jesus, burning with love for us, inflame our hearts with love for Thee. Jesus, meek and humble of heart, make my heart like unto thine! These prayers turned out to be surprisingly controversial , leading to insults being exchanged through the blockchain: ” Oh, and god isn’t real, sucka.

Stop polluting the blockchain with your nonsense. Typical messages are: Hi from 50BTC. Yours GHash. A common security hole on websites is cross-site scripting XSS [8] , where an attacker can inject hostile JavaScript into a web page viewed by the victim. Surprisingly, such an attack was possible with Bitcoin.

The above script just created a harmless dialog box, but a more malicious transaction could potentially steal the user’s bitcoins stored on the website. A brilliant mind, a kind soul, and a devious schemer; husband to Meredith brother to Calvin, son to Jim and Dana Hartshorn, coauthor and cofounder and Shmoo and so much more. We dedicate this silly hack to Len, who would have found it absolutely hilarious.

My apologies, BitCoin people. The idea is 5 creatures wander around the screen eating food blocks and breeding or dying. Unfortunately the code has a bunch of bugs and doesn’t work. Thumbnail of the original Bitcoin paper. Rickrolls Rickrolling is a popular internet prank, and Bitcoin is not immune. One rickroll was described above as part of the prayer dispute. Here are some of the images stored in the blockchain using this system: Some images found in the Bitcoin blockchain.

Wikileaks cablegate data A 2. Thank you Satoshi! Downloading the data from the blockchain is inconvenient since the download tool needs to be used on the chunks of 20 KB separately. It’s much easier to download the file from the internet. The blockchain contains the source code for Python tools to insert data into the blockchain and to download it. It also uses a checksum to make storage more reliable.

Here’s the code in the blockchain to insert data into the blockchain. While it says it was written by Satoshi Nakamoto the pseudonymous author of Bitcoin , that’s probably not true. And here’s the code to extract data from the blockchain. The download tool is slightly buggy – the crc32 has a signed-vs-unsigned problem which suggests it wasn’t used extensively.

Leaked firmware key and illegal primes This transaction has a link about a leaked private key, followed by 1K of hex bytes as text, which supposedly is the private key for some AMI firmware.

The change from that transaction was used for this transaction , which references the Wikipedia page on illegal primes , followed by two supposedly-illegal primes from that page.

The change from that transaction was then used for the Wikileaks Cablegate messages, implying the same person was behind all these messages. It looks like someone was trying to store a variety of dodgy stuff in the Bitcoin blockchain, either to cause trouble or to make some sort of political point. Email from Satoshi Nakamoto The following email message allegedly from Bitcoin inventor Satoshi Nakamoto appears in the blockchain.

It seems to be referring to the removal of some Script opcodes from the Bitcoin server earlier and making the corresponding change to the Electrum server. My guess is this message is someone pointing out a bug fix for Electrum in a joking way.

Be warned that I have not actually tested this patch. The first option for putting text into an address is to test millions or billions of private keys by brute force in the hope of randomly getting a few characters you want in the public address. This generates a “vanity” address which is a valid working Bitcoin address. Note that only six desirable characters were found, and the rest are random. You can use the vanitygen command-line tool or a website like bitcoinvanity to generate these addresses.

Many people have recently received tiny spam payments from vanity addresses with the prefixes 1Enjoy These payments don’t get confirmed by miners and the purpose of them is puzzling. The second option is to use whatever ASCII address you want starting with a 1 and ending with a six-character checksum. Since there is no known private key for this address, any bitcoins sent to this address are lost forever.

The motivation is that Counterparty is issuing their own crypto-currency XCP in exchange for destroyed bitcoins. The idea is that “proof-of-burn” is a more fair way of distributing currency than mining. Mysterious encrypted data in the blockchain There are many mysterious things in the blockchain that I couldn’t figure out, that appear to be encrypted data.

Between June and September , there were thousands of tiny mystery transactions from a few addresses to hundreds of thousands of random addresses sorted in decreasing order. These transactions are for 1 to 45 Satoshis, and have never been redeemed. As far as I can tell, the data is totally random. But maybe there is a secret message in the addresses or in the amounts.

In any case, someone went to a lot of work to do this, so there must be some meaning. Without the passphrase, they can’t be decrypted. By following the change addresses, we can see that after submitting the “Satoshi” uploader and downloader, the same person submitted the Bitcoin PDF. The same person then submitted five mysterious files.

Valentine’s day messages There are a bunch of Valentine’s day messages in the blockchain from a couple days ago. I assume someone set up a service to do this. How to put your own message in the blockchain It’s pretty easy to put your own character message into the blockchain. The following steps explain how. Take your character string and convert it to hex. Send bitcoins to that address and your message will show up in the blockchain when your transaction gets mined.

Important: those bitcoins will be lost forever, so send a very small amount, like 10 cents. My test message can be seen at the end of blk here. Summary People have found a variety of ways to store strange things in the Bitcoin blockchain. I have touched on some of them here, but undoubtedly there are many other hidden treasures.

The notes to this article provides hashes for the interesting transactions, in case anyone wants to investigate further. Notes and references [1] Clients store the gigabyte blockchain in the data directory.

The blocks are stored in a sequence of megabyte files blk nnnnnn. Syncing these files is why a full Bitcoin client takes hours to start up. Part of that transaction is an arbitrary coinbase field of up to bytes in the Script language.

Normally the coinbase field has data such as the block number, timestamp, difficulty, and an arbitrary nonce number. Normally, you start with a random bit private key, which is necessary to redeem Bitcoins.

From this, you generate a public key, which is hashed to a bit address. But inside the transaction, the address is stored as the bit 20 byte hex value. In normal use, you have no control over the byte hex value used as an address. The trick for storing data in the transaction is to replace the address with 20 bytes of data that you want to store. For instance, the string This is my test data turns into the hex data ‘d’. If you send some bitcoins to that address, the bitcoins are lost forever since you don’t have the private key matching that address , but your message is now recorded in the Bitcoin blockchain.

See my earlier article for details on how Bitcoin addresses are generated. If you do this for all the addresses, you get an ecoded file. This file turns out to be encoded in the obscure yEnc encoding, designed in for transmitting binaries on Usenet.
