what proof must one have to identify himself as Nakamoto Satoshi?

[n0ne]

What is the point of wanting to even know who the real Satoshi when it is obvious anyone can claim to be anybody these days. He should remain anonymous, that's good enough. For me, I would not believe if anyone comes out today with proof that he is Satoshi.

There is no need to find who the real Satoshi. Everyone having an expectation to see the real Satoshi is common thing. Staying anonymous is the what the network requires. Quite often we used to encounter different people coming up with the claim of being the real Satoshi. Nowadays that too have reduced as no one is able to prove themselves real Satoshi. Till the year 2120 this discussion will go on, and at some point conclusion will be reached assuming Satoshi to be dead.

Bitcoin is decentralized cryptocurrency, the only way for somebody to ever legitimately stake a claim to being Satoshi Nakamoto without getting laughed out of the building is cryptographically. He has sign a message from a well known Satoshi mined early block. That is literally the only only way, everything else is BS as we see with characters like Craig Wright.

Zero proof, I am sure that Nakamoto doesn't want to be known, so who ever comes forth to claim the identity knows better than everyone, he knew Nakamoto isn't coming, and claiming to be the Real Nakamoto can give him the drive juice.

Revealing who the real creator of BTC is means the decentralized part of BTC is officially broken, this is why I believe that the real Nakamoto isn't coming to the public.

There are people that communicated with Satoshi in the early days, which might still have information or data that only Satoshi might have known .. and that were not made public. I think if he signs an address that was linked to him with a message to those people, then it might authenticate his real identity.

He left a message in the early days when he launched Bitcoin, so I think he will do the same.. if he wanted to communicate with us again.    I would prefer that he would not try to reveal his real identity... because that will just create more troubles.

Attempting to prove identity is itself shady to me.
Because why did Satoshi go away in the first place to want to come back now and need to prove his (her,) identity? And why prove his identity in the first place? If he wanted to do anything like contribute to Bitcoin he could do that under any identity he wanted. Maybe he is already creating pull requests and reviewing changes in Bitcoin!
Only those who are set to gain something would want to prove something. There is nothing to be gained for Satoshi to prove his identity. Only losses, loss of privacy, maybe even security as his life may be in danger, etc.

Very on point, I don't see the need for identity proof by Satoshi since being anonymous is part of the original plans and features of Bitcoin and that is why, anyone can contribute to a network under any identity. Decentralization has eliminated identity proves and is needless for Satoshi to reveal his identity that is if there is an identity to the word SATOSHI, Identity verification is not part of BTC whitepaper and as much as we can we tried to remain anonymous and private so only those who have something to gain will come out trying to prove their Satoshi Nakamoto.

We always wonder who the real master mind behind the name of Nakamoto Satoshi the creator of bitcoin is.But what exactly would make you believe or convince you that "this" person is Satoshi if he/she ever decided to reveal himself.
There might be infinite wannabes and glory hunters wanting to rise to fame ,given the real Satoshi is one among them how would you go on about finding the right person.

If Satoshi returns back with his forum account here and tells who he is, then it’s very likely that most people will believe that he is the real Satoshi. Moreover he can also give a signed message of the Bitcoin address that he used here. This will give more believe from the people that he is the real Satoshi. But Satoshi kept this alias in order to hide his real identity. So it’s completely possible that Satoshi won’t come out and reveal his identity against this cruel masses.

Note that his account is banned from this place, according to theymos. So, even if he tries to login, he won't.

Moreover he can also give a signed message of the Bitcoin address that he used here. This will give more believe from the people that he is the real Satoshi.

Satoshi never disclosed his address(es), so any signed message from one of his "probably his" addresses isn't a proof of identity, but rather a proof of ownership of the private key. The only action that can act as proof of identity is to provide a signature from his never used PGP key[1][2].

I think an immutable proof of Satoshi's existence is right from his addresses. As far as I know his is one of if not the oldest addresses out there, holding bitcoins worth as much as billions of dollars. A fund transfer from one address to another through these addresses could be an indicator that they are still alive and breathing, but that itself could be fabricated should a hacker get hold of his wallets. Another would be signing a message from the addresses he owns, which could both give hint to who they really are, and of his existence as well.

All in all, I don't think he's needed anymore, as it stands today bitcoin is self-thriving and doesn't need a Satoshi Nakamoto to hold everything together. The enterprise has become bigger than themselves in an amazing fashion, and I think this is what he wanted in the first place.

Let's face it the crypto system is an open threat to the conventional economy and it was and still is a wise decision for Satoshi to remain anonymous for his safety because some sort of false narrative could be propagated against him and off he goes to jail.... Look at what is happening to Sam bankman fried.... Though you may say he's somewhat guilty but we all in the crypto space knows the impact of arresting such personality and the effects it will create in the already volatile environment we are... So you see why it's not wise for Satoshi to come out?

Sam Bankman-fried's situation is a very different one, SBF committed a crime by using people's money for his own personal gain and losing it, so it is correct for him to be arrested. SBF, CZ and other owners of centralized crypto exchanges, altcoins and services all did or are all doing things totally different from BTC or Satoshi, they created services that allow them to control and keep people's money and use it for their own profit and gain, their service also allows people trade shitcoins, lose their personal data to bad people, the government or blockchain analysis company, these has led to so many losses and cause for regulation outcry.

Satoshi created a network that allows people to choose what they want to do with their coins, a network that doesn't give him any control, but for the community and the owner of the money to control, a network that works perfectly without him ever needing to come out of his anonymity status. Satoshi didn't create a network that would warrant him to be arrested if he is known. Though the government may only attack him because he freed people out of their financial oppression.

I would say that whoever can produce a digital signature with the private key of the Genesis block address has the strongest claim to actually be Satoshi Nakamoto.
