Is “Satoshi Nakamoto” Really Adam Back?

The New York Times has a long article where the author lays out an impressive array of circumstantial evidence that the inventor of Bitcoin is the cypherpunk Adam Back.

I don’t know. The article is convincing, but it’s written to be convincing.

I can’t remember if I ever met Adam. I was a member of the Cypherpunks mailing list for a while, but I was never really an active participant. I spent more time on the Usenet newsgroup sci.crypt. I knew a bunch of the Cypherpunks, though, from various conferences around the world at the time. I really have no opinion about who Satoshi Nakamoto really is.

Why does it matter?

The article is nonsense. It compares the text writing styles of Back and Nakamoto. But compare their programming styles and you’ll see that they are very, very different people.

It’s easy to show that anyone is Satoshi Nakamoto.

Think of a person you would like to be Satoshi Nakamoto.
Interpret evidence in a favourable light that supports the predetermined conclusion.
Ignore any and all other evidence that doesn’t support the predetermined conclusion, and pretend it doesn’t exist.
Post the result and profit.

The more controversial the selected person is, the better. Then it gets more of those sweet ad views.

@ Bruce, All,

With regards,

“… impressive array of circumstantial evidence that the inventor of Bitcoin is …”

The thing about “circumstantial evidence” is it is all to often the prosecutor knows that it is,

1, “Not tangible evidence”.

And even when physical it is often

2, “Not of the crime”.

And worse,

3, “Not of the time of the crime”.

Or even

4, “Of or even close to the scene of the crime”.

To be blunt it’s in effect,

5, “fabricated” or “cherry picked”

Just to make someone look guilty because a third party thinks they can make another “look guilty” without being able to “show they are actually involved let alone guilty…

Or like the vast majority of us have no verifiable Albi for the crime”… Thus in effect are “easy meat”.

So now consider that we are dealing with a journalist “making not a case for justice 3” but to “sell a newspaper”.

So not even a member of state / federal guard labour or a prosecutor that should in theory not just “tell a tale”.

But further consider the harm…

Lets just say I could stitch together circumstantial evidence to say our host is the inventor of bitcoin, how much harm would that cause?

We already know in some places people gave been badly physically hurt by “thuggish criminals” after bitcoin etc.

Think of X that you would like to be Y.

(The rest of your list)

Is 99% of the “debate” that occurs on the internet and often everything else too.

The real “Satoshi Nakamoto” can easily prove they are them: transfer a single Satoshi to a designated wallet is all the proof needed.

Proving someone else (singular/plural) are the real “Satoshi Nakamoto” is next to impossible. Unless physical fingerprints can be found on proven hardware, all “evidence” will be circumstantial.

It is entirely unclear whether Satoshi Nakamoto is even alive. If so, they are sitting on one of the biggest fortunes on earth. Or they lost the keys to their Bitcoin holdings.

@I’m not Satoshi Nakamoto

Why does it matter?

As “Satoshi Nakamoto” controls between 750,000 and 1,100,000 bitcoins (>5% of Bitcoin) and is the largest single holder of Bitcoins, it does matter.

Currently, a conversion to post-quantum cryptography is under discussion in the Bitcoin community. The question what to do with Satoshi’s coins in that conversion (burn, store, or distribute) has real consequences for the Bitcoin market.

In a secondary point, a lot of moral and political intentions have been projected on “Satoshi Nakamoto”. A real life person might disappoint a large fraction of the cryptocurrency community for being an imperfect human being with ideas of themselves.

The New York Times article lays out a tidy chain of circumstantial evidence, but tidy doesn’t equal conclusive. In my experience, attribution in the cryptography and cypherpunk communities is rarely straightforward. People shared ideas across mailing lists and conferences, and influence is not the same as authorship. Ultimately, Bitcoin’s success is about the strength of the protocol, not the identity of its author.

Quote from the Times article:

“Adam Back, a British cryptographer and leading figure in the Bitcoin movement, sat on a park bench in Riga, Latvia, his shirt untucked under a brown coat. The filmmaker casually rattled off the names of several Satoshi suspects. At the mention of his own name, Mr. Back tensed up, strenuously denied he was Satoshi and asked that the conversation be kept off the record.”

Well you would, wouldn’t you? As of today, Back must surely be in hiding. 750,000 BC is worth enough for anyone to come and ‘lean’ on him. Denying it will just make them hit harder.

Okay, I admit it.

I was Satoshi Nakamoto.

But that was in a previous life — I’ve been reincarnated as an Internet Troll.

Seriously, the most plausible hypothesis I’ve read was that the putative SN is some guy who is now doing a long stretch in a Federal Penitentary some relatively serious crime and was tossed in the slam just about when the Nakamoto postings stopped.

As I say, plausible, not definitive and certainly unproven.
