The 1 million "Satoshi owned" bitcoins have been priced in by the market to stay put forever. Craig "Satoshi" Wright said he was going to move them, what are your opinions what would happen to altcoins prices if he stands by his word?

http://www.bbc.com/news/technology-36213588 Whether Charlie Sheen is actually Satoshi or not, he is not so desperate for money that he would dump coins. If coins have so far not moved then simply knowing who the main bitcoin dev was will not cause him to sell.

There is no fix. It is an inherent phenomenon of the economics of mining. Satoshi of course knew this. He was no dummy.

That's very interesting! Could you explain this a bit more?
If this was intended, what did Satoshi ultimately hope for?
Thank you for your time

I explained the economics centralization upthread, just search "sockpuppet1" to find all the posts.

Satoshi obviously intended for us to end up with a centralized token. What other possibility could there be?

Note Satoshi even wrote in the discussions with others, that he did envision Bitcoin's mining becoming controlled by corporations. All that ideological crap about "better gold" and "usurping financial institutions" was just putting lipstick on a pig.

Re: Theymos: “Bitcoins Belonging to Satoshi Should Be Destroyed”

With all the drama raging, everyone already at each other's throats, why would someone bring up quantum computers breaking Bitcoin and start talking about destroying Satoshi's coins?
Help me out with this Undecided

Maybe theymos was actually using reverse psychology to make a hidden point. That could be he is ridiculing those who say there might be a potential but unproven back door in Bitcoin, by pointing out that such unproven FUD would justify stealing Satoshi's coins in advance to prevent the hacker from causing havoc.

Perhaps he is slyly trying to refute my hypothesizing about a back door in Bitcoin (but my technical argument was not about a quantum computing attack).

Theymos defacto in effect admits TPTB_need_war might be correct with his technical allegation upthread that Bitcoin could possibly have a back door that could be cracked:

Edit: To be absolutely clear: I am not proposing (and would never propose) a policy that would have the goal of depriving anyone of his bitcoins. Satoshi's bitcoins (which number far below 1M, I think) rightfully belong to him, and he can do whatever he wants with them. Even if I wanted to destroy Satoshi's bitcoins in particular, it's not possible to identify which bitcoins are Satoshi's. I am talking about destroying presumably-lost coins that are going to be stolen, ideally just moments before the theft would occur.

This issue has been discussed for several years. I think that the very-rough consensus is that old coins should be destroyed before they are stolen to prevent disastrous monetary inflation. People joined Bitcoin with the understanding that coins would be permanently lost at some low rate, leading to long-term monetary deflation. Allowing lost coins to be recovered violates this assumption, and is a systemic security issue.

So if we somehow learn that people will be able to start breaking ECDSA-protected addresses in 5 years (for example), two softforks should be rolled out now:

Vindicated!

Well gleb gamow and SebastianJu both got temp banned too for similar reasons not too long ago.   At least the forum rules are being enforced somewhat fairly.

Which similar reasons?

Tisk tisk. Keep your posts in Meta or ...

"Tsk. Tsk" are the words I expect to hear from your grandmother calling you to have your daily scolding. I don't cowtail to theymos' delusions, technical incompetence, and censorship.

If I may express some frustration w.r.t. to desire to troll and censor, "Fuck you and theymos too". TPTB_need_war doesn't care. He can always subvert any ban.

Any way, TPTB_need_war is too busy programming. He has provided a public service.

And yes he was banned for revealing a potential back door in Bitcoin[1]. Just goes to show how theymos and gmaxwell are protecting you.

And yourself, how about you grow up and learn to tolerate open dialogue.

P.S. permanently banning TPTB_need_war is perfect for his plans. I hope theymos has the balls and the technical knowledge to attempt it.

Also I didn't start this thread. I didn't ask for this thread. I wasn't intending to post in this subforum at this time. Blame the person who created this thread. I read so much misunderstanding and slander of TPTB_need_war that required clarification and correction.


[1] In the ban message and in theymos's private message which is quoted by TPTP_need_war, theymos indicated the reason for the ban in addition to his incorrect claim of spouting technical nonsense, he also alleged spamming of messages in several threads and the ad hominem attacks against others. Theymos appears to be protecting Foxpop who hurled ad hominemfirst, and CIYAM who also hurled ad hominem first. TPTB_need_war had stated that the reason for posting in numerous threads, is because the mods allowed people to make numerous duplicate threads on the same topic about Craig Wright claiming to be Satoshi Nakamoto. Do take note that at the time he was having the debate with CIYAM, he had thought that Craig's signature had matched the hash of the Sartre text because he was misled by sloppy reporting and sloppy writing of those who did the technical analysis. It was only later that he learned that was not the case. And after all, his alleged back door in Bitcoin remains potentially true. You don't ban people for these incorrect reasons and expect to remain respected and expect others to not want to overcome inappropriate use of influence. There is too much ignonymous influence in Bitcoin.



...absolutely petrifying.    Cry

You did it to yourselves. Now you will reap what you have sown.

I am an American who doesn't share your looney European Marxism. Last time it was a million in the gas chambers. Let's see how it goes this round.

Shut up and get back to work on building your copy-leftist clusterfuck.

I don't associate with scum like you. I compete and overcome. Bye. Unless that is you want to say those words about my kids to my face. Otherwise we have nothing more to discuss. Enjoy your life.

Facts are more efficient than fud
Personally, I don't think Craig is Satoshi, and not because of his looks. I don't care what he looks like. the thing is he isn't providing enough information to give enough proof that he is actually Satoshi.

The lack of a signed message, saying he'll publish documents and not have them available immediately, it all seems just a bit too sloppy and drawn out for him to really be Satoshi.

What is so ironic from my perspective (and I suspect the elites are also having a good chuckle about the blindness of you "useless eaters/cattle") is that once you review all the facts (<--- click to know what Satoshi Nakamoto really is), the fools are those who even entertain any thought that Satoshi could be a person.

The elites are playing us like a fiddle with BitCON. Seriously. I didn't reach this conclusion without extensive thought and rationality.

my assume if Nick szabo is the one of the team

Zero chance. Nick is both not smart enough and doesn't code prolifically enough.

Have you ever read Delueze's Societies of Control? Bitcoin fits great with this agenda, though I think Deleuze would say it's the natural progression of Capitalism and more the TPTB playing themselves than leading anyone--pay specially attention to the discipline society being ousted for control society when reading. While I think some in Bitcoin are trying to make it more private, I don't think it will ever achieve any degree of great privacy as it will never be at the protocol level and require you going through observable way stations that require you to borrow further and further underground--"Neo, what's in your wallet?"

I am aware of your past BCT posts about the inadequacies of asymptotic complexity arguments. Smiley

I don't share your romantic guess of who created BitCON.

Btw, Craig says the name Satoshi comes from "the book" about the House of Morgan:

https://forum.bitcoin.com/bitcoin-discussion/the-name-satoshi-comes-from-satoshi-david-character-from-the-house-of-morgan-t7619.html

And Nakamoto means "in the book" in Japanese.

And Julian Assange knew Craig in 1996:

https://www.reddit.com/r/Bitcoin/comments/4hozs5/wikileaks_on_twitter_wed_like_to_thank_satoshi/d2rdg7u

Don't forget that (I was told) a House of Rothschild person was sheltering Assange when he was still free in the UK. And note now how the UN is attempting to supercede the UK's authority on the case. There is always a globalist plan for these pawns, including Edward Snowden.

I think someone paid off Craig to discredit Matonis and Gavin. Gavin has now lost commit access.

The danger is not that BitCON fails, but that it becomes the new totalitarian digital currency.

Hope you are aware that ostensibly the Dr. Craig Wright can't be proven to have made the blog posts, which implicate him:

http://craigswright.com/

Meaning a failure of Bitcoin is not the big problem we face. I hope for the failure of Bitcoin instead of it scaling by becoming centralized. The danger is that many vested interests want Bitcoin to continue even if it is centralized. Centralization doesn't necessarily kill Bitcoin, unless the centralized controllers kill it. Too many tinfoil hats want Bitcoin to succeed and be "the better gold" even if it is centralized and controlled by the combination of China's miners, Larry Summers' 21 Inc., and Blockstream.

The annals of the crypto-currency arena is littered with ignonymous players. Similar to the birth history of President Obama, theymous and the Gman are nearly entirely ignonymous. I've seen only one photo of theyman. I can't find any LinkedIn for the Gman, his educational history, which high school he attended, and where he was born, even though most of his colleages at Blockstream have a LinkedIn. Googling "Gregory F. Maxwell" only returns an address and phone in Parker, Colorado and the following Wikipedia Commons page:

https://upload.wikimedia.org/wikipedia/commons/d/d2/Gmaxwell-boat.jpg

I note the Gman's use of the "rascist" attack against both TPTB_need_war and against Zooko @ Z.cash. And in the above linked Wikipedia Commons, his support for viral "copyleft" licenses that force companies to refuse to use open source because they aren't allowed to keep any portion of their derivative works as proprietary code. In other words, some of sort of totalitarian socialist/Marxist philosophy similar to FSF's Richard Stalman. Dangerous.

Readers again you may want to quote this message because we can't be sure if mods won't get "happy finger" and nuke this post.


Edit: these 1996 posts by Julian Assange says everything you need to know about whether he is a eugenics globalist:

but the most probable conclusion is Satoshi was one man and he was simply mistaken

One man can't accomplish what "Satoshi" did with such precision. It was a large group of experts. No doubt about it.

You guys who have no experience in doing something like this, love to have your James Bond fantasies. But you are completely out-of-touch with the reality of actually doing what "Satoshi" accomplished.

You've made at least two mathematically illiterate errors in that quoted text:

1. Testing that double-hashing fulfills some criteria you have prechosen, says nothing about security against cryptoanalysis which your criteria has not considered.
2. Securing a password by iterated hashing (because it requires the dictionary attacker to perform the iteration cost on each dictionary trial) says nothing about the increased vulnerability of collision cryptanalysis. You are conflating two separate issues of security.  Roll Eyes

Of course double hashes can't be applied to securing passwords as in case #2 above. That requires 1000s of hashes. Double hashes would be a silly joke in that case.

So thus you've admitted that double hashing adds no protection against a computationally bounded adversary (i.e. the only kind of adversary that exists in the real world). So why did Satoshi add double hashing to Bitcoin  Huh

https://www.google.com/search?q=Ferguson+double+hashing+length+extension+attacks+bitcoin.stackexchange
https://www.google.com/search?q=double+hashing+length+extension+attacks

I learned at the above that double hashes are required to stop the length extension attacks which can never occur in Bitcoin and thus which Bitcoin doesn't need to defend against, so why are you "saying that we are doomed" for unnecessarily adding the weaknesses of double hashing to Bitcoin?

So thus you've admitted that double hashing protects against length attacks, but length attacks can't occur in the Bitcoin. So why did Satoshi add double hashing to Bitcoin  Huh

Don't tell me you arrogantly claim your grand insight is enabled because Bitcoin does hash(hash(M)) instead of appending part of the input to the output of the first hash(hash(M||M')||M') as is always done for HMAC where the idea for deploying double hashing originates.

As I interpret TPTB_need_war's explanation of the potential vulnerability (and I'm the canonical source of such interpretations, lol) due to a Boomerang differential attack, that Satoshi adopted the incorrect way of doing double hashing is precisely what makes Bitcoin open to the hypothesized vulnerability.
 
So why did Satoshi add the incorrect form of double hashing to Bitcoin  Huh

If you were correct, then every brother and his uncle should be trying to find a cryptographer help them crack Bitcoin and become $millionaires by spending old coins that were allegedly mined by Satoshi and may otherwise never be spent if Satoshi is truly dead.

I tried to be nice to theymouse and Gmaximus and discuss in an open forum about how it might be possible to break Bitcoin so that it could not make one person very wealthy. But they want to play hardball, so...

Please kindly quote my post in case it is deleted by the mods.

P.S. My personal opinion is I speculate Craig Wright was hired by core to discredit Matonis and Gavin. And I was hired by myself to do the same to "core"; and I speculate "core" appears to be affiliated with the aforementioned individuals. Velvet gloves are off. No more nice guy. Bitcoin is a failed clusterfuck with 70% of the hashrate attributed to China, and one former cattle farmer in China planning to increase that to 98%. The miners and Blockstream are ostensibly colluding to put soft fork versioning into SegWit. There is $1 million per day flowing from n00bs into this raping system that ends up in miner's pockets and other connected parties. Electricity likely charged to the collective via State funded hydroelectric infrastructure. And the ecosystem has no real utility outside of gambling, scams, and other nefarious use cases.

Why did the mods ban TPTB?

How does censorship help the crypto movement?

Where did these posts go?


Wholly shit! I am contemplating the possibility that Craig has revealed that who ever created Bitcoin put a backdoor in it!

As I already explained, the signature Craig has provided proves either he has cracked something about the way Bitcoin uses SHA256 or he has Satoshi's private key. Afaics, there are no other mathematical possibilities.

But note this small detail:

You'll note that Bitcoin, for reasons known only to Satoshi, takes the signature of hash of a hash to generate the scriptSig. Quoting Ryan:

Well that isn't so insignificant of a detail when you think more about it in this context.

A cryptographic hash function has a property named collision resistance. Collision resistance is related to preimage resistance in that if we have a way to quickly find collisions, then if the preimage is collision then we also break the preimage resistance for that particular hash value.

Collision resistance is normally stated as the number of hash attempts required to find a collision or the number of rounds to break collision resistance with reasonable hardware. Normally this is exponentially less than computing the SHA256 hash function 2256 times. For SHA256, there are collision resistance attacks up to 46 of the 64 rounds of SHA256 (and 52 of 64 rounds for preimage attack).

So what happens to collision (and preimage in this context) resistance when we hash the hash? Well all the collisions from the first application of hash become collisions in the second hash, plus the new collisions in the second application of the hash thus increasing the number of rounds that can be attacked.

It seems likely that Craig has identified the back door that was placed in Bitcoin as explained above, and used his supercomputer access to find a preimage of SHA256.

If am correct, this is major news and Bitcoin could crash.

I urge immediately peer review of my statements by other experts. I have not really thought deeply about this. This is just written very quickly off the top of my head. I am busy working on other things and can't put much time into this.

"Your buddy was banned for 10 days, lol

Theymos replied when I sent him a copy of the prior message (didn't mention nor quote you) with the following message and he banned me from BCT for 10 days.

Quote from: theymos
Your technical claims are nonsensical, but yet you keep spamming them and resorting to ad hominem arguments. For example, there is a known attack on reduced-SHA-256 with 52/64 rounds, but the attack has complexity 2255.5. So the best-known attack on SHA-256 causes it to lose half a bit of security when the number of rounds is reduced. It's nothing. Saying that we're doomed (and spamming about it everywhere) because someone might possible find a way to invert SHA-256 is like freaking out because there might be psychics capable of reading keys from people's minds.

Take a break...

Clearly he either didn't bother to read my linked post (which I also provided to him in the quote) wherein explained I wanted to explore theoretical security concerns about double-hashing (which btw is not the same as what Merkel trees do), not not single hashing which I am positing may have different security attributes. In that linked post, I also quoted wherein I had always made a disclaimer that readers should wait for expert peer review and that I hadn't expended a lot of time on the issue. Also the ad hominem starts from his tribe attacking me, such as for example Foxup's condescending posts. I responded in kind after it was clear that Foxup wouldn't stop his snide attitude and follow a more fruitful one.

Also theymos is disingenuous by cherry picking the preimage attack at 52 rounds which requires 2255.5 trials and not also mentioning the pseudo-collision attack at 46 rounds with only 246 trials:

https://en.wikipedia.org/wiki/SHA-2#Cryptanalysis_and_validation

The point of my theoretical inquiry is whether double-hashing might open an opportunity for a new cryptoanalysis breakthrough such as the Boomerang attack given the significant structure at the midpoint the doubling the hash ostensibly introduces.

And why are theymos and gmax so worried about allowing information to propagate freely and letting readers make up their own minds. Why do they feel they need to control the minds of readers.

So yes it appears you are correct. I hit the root nerve. Theymos and gmax are ostensibly in bed together and can't tolerate any theoretical discussion.

None of this is going to help them, because they both have only left thumbs.

I also don't believe CW is Satoshi. But that isn't my point. I explained the salient point more concisely here which is really about ridicule, censorship, and manipulation of public opinion instead of rational, well elucidated, and amicable/patient/unencumbered reasoned discussion (i.e. acadamics versus corporate fiefdoms):

https://bitcointalksearch.org/topic/m.14766475

Please also read the subsequent to the above linked post as I broad stroked some of my theoretical concerns about the double-hashing in Bitcoin.

Theymos is allowing me to continue so I think it is possible that Theymos is helpless due to not being capable himself of leading technologically. So appears he may be trying to appease Greg while also allowing for the minute possibility that someone else could accomplish in code and in reality something as relevant. I think I respect Theymos if this is the case. But we don't really know what is going on behind the scenes. I am at the point now where I really want to ignore everything on BCT and Reddit. My discussions about programming language theory are going very well at the Rust forum. Did you see I solved the age old computer science problem known as the Expression Problem articulated by Philip Wadler in 1999:

https://bitcointalksearch.org/topic/m.14757751

https://bitcointalksearch.org/topic/m.14035614
(search for the phrase "Also I don't understand how you calculate 20% increase" within that post)

TPTB_need_war, you cannot prove nor disprove that the Sartre text Craig Wright supposedly hashed is a collision for SHA256.

I asked you to not do what you just did above:

Don't cherry pick my context to make inane non-rebuttals which side-step my holistic set of points.



You also pointed out that he supposedly has access to a supercomputer. Even with access to a supercomputer, he would not be able to find a collision as other researchers have already tried. Simply having a lot of computing power does not mean that he can find a collision.

Alternatively, Craig could have found a vulnerability in sha256, in which case a lot more things than just Bitcoin is screwed. If Craig did not responsibly disclose such a vulnerability and instead exploited it, this would be incredibly sketchy and dishonest behavior.

The point is that with a supercomputer together with a new cryptoanalysis break, the two together might be required to accomplish the attack. I want you to know that if China's pools see nearly all the mining shares, then they are viewing about 268 of SHA-256 hashing power per annum which may or may not be fulcrum. Don't presume you know all the theoretical attacks that are possible.

The theory that the sha256 double hash is weaker than sha256 is false. It has been proven that performing multiple iterations of a hash is more secure than just one iteration. Specifically, many websites will store users passwords in the form of a multiple iteration hash.

You've made at least two mathematically illiterate errors in that quoted text:

1. Testing that double-hashing fulfills some criteria you have prechosen, says nothing about security against cryptoanalysis which your criteria has not considered.
2. Securing a password by iterated hashing (because it requires the dictionary attacker to perform the iteration cost on each dictionary trial) says nothing about the increased vulnerability of collision cryptanalysis. You are conflating two separate issues of security.  Roll Eyes

I am done speaking to these amateurs. Waste of my time.
