How a PhD Student Unlocked 1 Bitcoin Hidden In DNA (vice.com)
dmoberhaus writes: A 26-year-old Belgian PhD student named Sander Wuytz recently solved a 3-year-old puzzle that had locked the private key to 1 Bitcoin in a strand of synthetic DNA. Motherboard spoke with the student about how they managed to crack the puzzle, just days before it was set to expire. From the report: "As detailed by Nick Goldman, a researcher at the European Bioinformatics Institute, in his pioneering Nature paper on DNA storage, to encode information into DNA you take a text or binary file and rewrite it in base-3 (so rather than just ones and zeroes, there are zeroes, ones, and twos). This is then used to encode the data in the building blocks of life, the four nucleobases cytosine, thymine, adenine and guanine. As Wuyts explained to me, coding the data as nucleobases depended upon which nucleobase came before. So, for instance, if the previous base was adenine and the next pieces of data is a 0, it is coded as cytosine. If the next piece of data is a 1, it's coded as guanine, and so on. After the data is encoded as synthetic DNA fragments, these fragments are used to identify and read the actual files stored in the DNA. In the case of the Bitcoin challenge, there were a total of nine files contained in the DNA fragments. The files were encrypted with a keystream, which is a random series of characters that is included with the actual plain text message to obfuscate its meaning. The keystream code had been provided by Goldman in a document explaining the competition.
After running the code, Wuyts was able to combine the DNA fragments in the correct order to form one long piece of DNA. After working out some technical kinks, Wuyts was able to convert the DNA sequence into plain text, revealing the private key and unlocking the bitcoin (as well as some artefacts, including a drawing of James Joyce and the logo for the European Bioinformatics Institute). He had cracked the puzzle just five days before it was set to expire."

So what?
It's not like people are hiding stuff in DNA often.
He hid a private key. A string of text. That's it. The story has nothing to do with cryptocurrency.
These guys stored a video clip in DNA.
Circles, like prokaryotic DNA?
Can this autism kroner bullshit finally crash? Does nobody understand the price is artificially inflated by the the tether money printer?
The funniest thing is that bitcoin true believers were all about shitting on fractional reserves, but now that tether is printing fake money, they are all about fractional reserve scamming
after all the hubbub of the BTC markets these days (even though comcast, 1 evil company still has a nearly equivalent market cap) I find this story to be both entertaining and relevant to the technology. Other BTC news stories are just not as fun or insightful, mostly about money grubbers and corporate cronies gaining/losing whatever, just don't care anymore! I wanna see a DNA blockchain now, can we put wifi chips in pigs and code their dna with the blockchain info? Or how about a DNA interface with a raspberry pi? Can anyone tell me / link me about DNA interoperability?
if he would have worked faster, his 'prize' would have been $17k instead of 10k.. no.. 8k.. oh, wait.. 11k......
But was it stored as big data in the DNA-cloud as a service?
Picard received one section of the private key after the mysterious death of his old mentor - but he didn't know what it was at first, since they don't use money anymore in the 24th century. However they eventually figured out where more parts of the private key were, even though a Klingon captain and Tara King tried to interfere. Finally they got to the last planet, where the shapeshifter lady from DS9 gave a little holographic presentation.

This type of story is about as Geeky / Nerdy / Technology based as it gets, and the modern day Slashdotter does nothing but talk it down.
Before this thread is done, we'll have Trump, Russians, guns, Hillary, luddites, a GD hosts file that can fix anything, things that go Moo, all sorts of slurs and a few homophobic topics to wade through.
I don't think it's Slashdot that has lost its way, but rather the clientele that frequent these parts nowadays.
You would think Slashdot was a subreddit by the way folks act around here anymore.
Help! I want to unlock the hidden value in my own DNA. Will this method work for me, too?
Though Star Trek made it much more boring.
No that would be Trump for obstruction of justice.
Last I Iooked there were four bases, not three....
Shouldn't DNA need base-4 encoding ? It's GCAT... Using base-3 as described, how is a sequence of GGAA encoded, for instance ?
This is insane and NOT funny:
https://www.enbridge.com/energ...
"Bitcoin is consuming enough energy to power Denmark for a year
Mining the cryptocurrency ‘consumes a ridiculous amount of energy’ estimates suggest"
For those of you who live in the US: Denmark is a small country up the north of Europe with less than 6 million inhabitants. In terms of civilization, it is more advanced than the US. This means that they consume energy in abundance.
You see, we Belgians are not only good in making beer, waffles, fries, ....
On a long enough timeline, the survival rate for everyone drops to zero.
in DNA during the war
At no point in the challenge was anything actually stored in actual DNA
Finally we get an interesting article here, and the moron patrol is out in full force.
FTFA: "During this presentation, Goldman distributed tubes of DNA in which he had encoded the key to a digital wallet containing one bitcoin." Near the end of the contest, there was a reminder tweet, and this student "requested a DNA sample from Goldman" and "also had access to sophisticated tools for genome sequencing."
I wondered that as well, but the choice seems deliberate. The PDF says a single "trit" is encoded as the difference between each nucleotide and the next in the sequence, explicitly to avoid sequences with repeated nucleotides. For any given nucleotide, there are only three possible non-repeating values. The PDF goes on to mention that every other segment is reverse-complemented, and that this choice of non-repeating was important in order to readily determine whether any particular segment had been reversed or not.
He deserves that bitcoin!
Except I was wondering why base 3 instead of base 4, which would seem to make more sense considering that there are 4 amino acids involved. But is it really base 3, or is it something like base 3(rot1)?
He had cracked the puzzle just five days before it was set to expire.
Cracked the puzzle?!! I'm sorry, but this is just stupid. There was no puzzle. The supplementary document provided by Goldman provides a precise specification for how the files are encoded. The only thing an interested person had to do is just apply that specification to a decoding task. Happy for the grad student, though, who has probably doubled his income this year.
It's really base 3. One "trit" is encoded as the transition from each nucleotide to the next. With no repeats, there are only three possible choices for the next nucleotide in the sequence. The PDF goes on to mention that every other segment is reverse-complemented, and that this choice of non-repeating was also important in order to readily determine whether any particular segment had been reversed or not.
If you want to get in on the cryptocurrency mining scene, you need a good motherboard that allows for multiple GPUs: ASRock H110 Pro BTC+, ASUS B250, Biostar TB350-BTC, and GIGABYTE GA-H110-D3A.
