61  Bitcoin / Bitcoin Discussion / Re: RAOUL PAL: Bitcoin Is Worth $1,000,000 on: November 12, 2014, 01:04:57 PM
total bitcoin or one bitcoin?
one bitcoin will never reach 1 million $, let's focus on the 10k $

I have done a calculation before that if all fiat was pooled into Bitcoin one Bitcoin (after all are mined) would be worth 2.6m$, total bitcoin market cap is currently already at $ 5.2 Billion $.
62  Bitcoin / Bitcoin Discussion / Re: Was there only one version of the original whitepaper? on: November 12, 2014, 01:01:29 PM
Satoshi spoke about Bitcoin on the cryptography mailing list before the release of the actual white-paper.

I'm pretty sure the whitepaper itself only had one release date.
63  Bitcoin / Bitcoin Discussion / Re: 3 Bitcoin Doomsday Scenarios I can't find much discussion on... on: November 12, 2014, 12:56:50 PM
While I've seen 51% and Bad-actor/rational-actor type scenarios being discussed ad nauseam, and in-depth, my searches for any sort of unpacking of the following scenarios have been fruitless:

1) "Stealth" code changes, that could get slipped in via an update, to modify network operation in some unforeseen, but yet-to-conceive exploitable way.
How huge a social-engineering effort would this take?
Do the huge-pool-guys vet every line of code themselves?
Does anyone log- and track stats on how quickly updates propagate throughout the network?

2) Someone like the World Bank establishing their own, incompatible network.
...coupled with an international media- and marketing campaign, backed by much more finance than the Bitcoin network, perhaps even offering lucrative-by-comparison shares in their new venture, to current Bitcoin players.
Once the mainstream is persuaded by the resilience and power of crypto-currency technology, it seems natural that they would adopt it... on their terms... doesn't it? What would the first ripples of this look like? Which banks are the key stakeholders? Is Bitcoin leading the pack to bank-adoption?

3) Computer intelligence optimizing ("cracking") the protocol
...potentially silently taking control of the network (without anyone noticing) only to wield its power at some opportune watershed moment. Yes, I know, Sci-fi...The moment we have all been waiting for... with it's plausibility-spectrum all the way from "impossible" and "maybe in 100 years", to "an AI (or CI as I like to call it) will be algorithmically cheap enough to run on a smartphone", all the way to, "the *insert multinational organization* is already run by an AI." (eg. http://dilbert.com/blog/entry/how_the_robots_will_take_over/)

Sure, on the surface, the latter two scenarios are very hypothetical and unlikely... yet, if Bitcoin *is* the biggest hedge against global economic stability, doesn't that in fact highlight their relevance?...

But here are the stats that are within arms length, and I'd like to see... (shouldn't be hard to compile, even collect as part of the protocol...)

4) Isn't it perhaps most relevant how each GH is powered, and how easily that power can be removed by tactical means
...to diminish the network hashrate as part of a global co-ordinated multi-faceted strike, the GH taken out only to come back up to a network (and world?) beyond its recognition? Eg. How stable is the US national grid? Compared to those of other countries? What proportions of what countries' power grids run the internet? What is the minimum number of power stations that needs to get taken out? What is the minimum fire power required and the cost thereof? Or actually, how many steel poles (of neglible cost) of what length would be needed to short out said power supplies?

5) Add to that security. Who holds this metric: How secure is each GH?
ie. How many layers of security? How agile is its management? How rapidly can the system be secured and restored to a previous point in time?

Any links welcome... particularly to a Wiki or new https://blockchain.info/pools pages monitoring metrics relevant to any- or all of the above. I'm fairly certain the intelligence agencies of the world keep tabs on the above, but shouldn't it be out in the open? How better to guard against it than having it in the public domain?

I suppose, in the spirit of Bitcoin, I have to post a wallet address here. If it reaches 10BTC (my living expenses are cheap), I will dedicate one month to compiling the best sources of the above information, as professionally as I can, and post it here. 1EfnAXe2dyuKiVXfGyoSBMSKqvzzQcfr3L


I'll go ahead and answer most of these without too much hassle....



1) "Stealth" code changes, that could get slipped in via an update, to modify network operation in some unforeseen, but yet-to-conceive exploitable way.
How huge a social-engineering effort would this take?
Do the huge-pool-guys vet every line of code themselves?
Does anyone log- and track stats on how quickly updates propagate throughout the network?

Every merge, or pull request on Github get's looked at by Core bitcoin developers, so unless you get them all in on the scheme it simply won't happen. There are also a lot of separate developers that work on the code in their free time, you can see all this on the bitcoin Github which can be found here: https://github.com/bitcoin/bitcoin

2) Someone like the World Bank establishing their own, incompatible network.

Anyone is free to start their own big "bitcoin" competitor, just look at all the alt-coins that are out there, or for example governments like Ecuador that have "banned" Bitcoin and say they want to start their own crypto currency. But judging from the popularity and the short lifespan of most alt-coins it seems that not too many people are as interested in them at all as much as they are in Bitcoin.

3) Computer intelligence optimizing ("cracking") the protocol

The unlikeliness of cracking the Bitcoin private keys can be found here: https://i.imgur.com/CzyO1yv.jpg  --- On a side-note, the protocol is as secure as it's code and the miners that secure the blockchain. As long as the code is secure it's very unlikely of a flaw massive enough that could damage the protocol as a whole.

4) Isn't it perhaps most relevant how each GH is powered, and how easily that power can be removed by tactical means

In the unlikely event that all mayor pools would be hit in a coordinated effort to kill the networks hashrate, I'm sure that a lot of miners within a few hours would step over to decentralized solutions like P2Pool, etc. In which case the entire internet would have to be taken down.

5) Add to that security. Who holds this metric: How secure is each GH?


The main security is the protocol which is secured by cryptography and is extremely unlikely to be cracked (refer to the image I posted before, even by quantum computing), then the blockchain is secured by the miners that perform work to secure it. Judging by the exponential growth in hashrate that we've been experiencing for the last 2 years it's also unlikely that anyone will secure a big enough share (51%) to threaten the network.

In the case of a split of the blockchain the network can be restored to previous states relatively simple (has been done twice before in 2013), where we forked away from the longest chain and continued on a different one.

There you go, all questions answered and it didn't cost anyone a single bitcoin.

I recall they've said before that they've stored it on a USB so you're not getting at it if it's offline.

All bitcoins even when the private keys are stored offline are still in the blockchain.

69  Bitcoin / Bitcoin Discussion / Re: How governments/ISPs can easily crash Bitcoin on: October 31, 2014, 11:36:39 AM
*for sure, many people send/receive/store their private keys unencrypted,  e.g. when generating paper wallets online

This usually happens locally on your browser except if you are creating your private keys through a malicious web page... You have to worry about the code the web page is serving you and not about your isp...

Generate paper wallets disconnected from the internet is the general consensus.....

To OP: Private keys should only be stored locally, on your own computer, encrypted. They should never be send over any network and Bitcoin does not send private keys when broadcasting a transaction.

So now, next to "too big to fail" we also have "too small to succeed!"... Interesting theory.

So I guess we won't see any small startups turn big commercial company anymore.  Roll Eyes

Here's my public key, you have to import it. Then send me the lockbox so I can import it. Don't forget to fund it Smiley. From there on the funds can ONLY be spend if we both sign the transaction.

this transaction will not become famous in any way.

I am less concerned about creating a "famous" transaction, and more interested in getting this specific job done.  
I also am interested in trying something new, and pushing the boundaries of the upcoming peer-to-peer decentralized economy that Blockchain technologies will bring on.


Religious wars aside, the amount I am proposing translates to about $68.

And if someone in San Francisco wants to help, but that's too cheap to make it worth their while, tell me that!


I'll be home in a few hours and then I'll post one of my public keys here :-).

If you get armory working I have no problem at all being the multisig intermediary for this transaction, do you know how it works? If you need an explanation let me know. It's rather simple. Smiley

edit on how the multisig transaction would work:

Create multi-sig lockbox

======================================================
Enter your public key
                                =====>>   fund lockbox  ===>> I import your lockbox
Enter my public key
======================================================


Now we can only spend the funds if we BOTH sign the transactions.

It is explained in more detail here: https://bitcoinarmory.com/about/using-lockboxes/

edit: The worst I could do "scam-wise" would be not to sign the proposed transaction and leave the funds stuck in the multisig address forever, which would do absolutely nothing for me...
74  Bitcoin / Bitcoin Discussion / Re: Gavin Andresen Proposes Bitcoin Hard Fork to Address Network Scalability on: October 28, 2014, 10:32:17 AM

High transaction fees:


7 tps limit:

5 bitcoins (transaction reward) / 4200 (tranactions per block) = 0.001190 transaction fee. Way too high for the consumer paying his hamburger at a restaurant.

Actually, that's about the price he is currently paying due to credit card fees, it's just hidden so he doesn't know he's paying it.

True, but with the prospect of increasing value it would probably raise a lot. That is why we so desperately need this change to block size to allow more transactions per block, which will in turn lower transaction fees (as demonstrated in my high frequency trading example) Smiley.
75  Bitcoin / Bitcoin Discussion / Re: Gavin Andresen Proposes Bitcoin Hard Fork to Address Network Scalability on: October 27, 2014, 12:44:52 PM

I followed the sidechains AMA.  Nothing new in that story at all, and nothing whatsoever which would support much of what you've been saying.

I will say that I'll expect sidechains impact on alts to be one of 'separating the wheat from the chaff.'  I believe that a fair number of alts were created to address some legitimate and valid needs that the the designers felt important.  Probably a majority of alts were created as pump-n-dump scams.

Alts which were created for the right reasons probably largely lamented the fact that they could not let Bitcoin do the heavy lifting as the actual value component.  These should be absolutely delighted to switch to a sidechain implementation.

OTOH, I foresee howls of rage and despair from those alts which are pump-n-dump scams designed with the hopes of making some early adopters rich.  I suspect that a fair amount of the negativity toward sidechains is from this corner right now because I can see no other legitimate complaint against sidechains.  This from a risk perspective, economic perspective, philosophical perspective, or any other rational perspective.  At least not one that is based on any skin-deep understanding of things.  (Actually, I take that back; those desperate to destroy Bitcoin as an empowering technology for individuals will also be quite alarmed by sidechains.)



I believe the main reason why we're in disagreement is because I think that the focus should be aimed at solving problems on the biggest and most secure blockchain in the world (Bitcoin), rather than implementing or trying to implement sidechains so we can incorporate a lot of smaller, let's call them ways to exchange different "tokens". The fact that this is driven by a for profit organization which will actually be touching the Bitcoin codebase and that has centralization on it's agenda concerns me greatly.

Hence I'd rather see us all working in unity to solve the problems we're facing on the main chain, rather than anywhere else.

77  Bitcoin / Bitcoin Discussion / Re: [ANN] Bitcoin blockchain data torrent on: October 27, 2014, 12:25:01 PM

I've been seeding the new torrent for 2 months now on a well connected server and have a seed ratio of 548. That's about 12 TB uploaded by one server in 2 months. I'm wondering if this is all due to people setting up full nodes, or if something else is happening here.

If you are a long term seeder are you getting similar results?

Armory likes to use it

This exactly, armory loves using this torrent. I've been seeding it for quite a while now. I tried out the download speed yesterday from this torrent and got around 25MB/s (around the max of the connection I'm using at home). I'm sure it would be even faster on my business connection.

Either way, keep seeding and everybody thanks for providing this service.

LOL!  OK.  And you know this with enough confidence to state it as a fact how again?

they have actually included a part in their contract that states if they think the company is acting maliciously they can leave at any time,
That's a bad thing?!?

probably because they can realize what is going on already.
If that's so then why in the fuck would they have even associated in the first place?  Work on your critical thinking skills a bit will ya?

They still work on the main Bitcoin code as well.
Thank God!

79  Bitcoin / Bitcoin Discussion / Re: Gavin Andresen Proposes Bitcoin Hard Fork to Address Network Scalability on: October 26, 2014, 07:46:17 PM
A handful of large organizations probably could run Bitcoin at these rates but realistically that's about it, and at that point they may as well do away with the blockchain itself and make it a real-time system like VISA.  That's why clued in folks like the blockstrream guys are looking around for a solution which will let Bitcoin scale to these levels without abandoning the very desirable aspects of the solution that it has today.
Pretty sure satoshi talked about light clients for the masses.  Also pretty sure VISA keeps a ledger.  Are you suggesting that "clued in guys" have insider knowledge that storage technology isn't going to continue to grow and get cheaper?  Do you also think "clued in guys" are writing solutions that pay people to mine things other than bitcoin are doing so completely philanthropically and not out to make a buck?  Is there any real evidence that sidechains aren't just going to be the new altcoin?

Well, the 'clued in guys' who associated themselves under 'blockstream' just happen to be among the most productive and thoughtful of the Bitcoin developers and maintainers.  I've personally paid pretty close attention off-and-on for some time now since I have a fair bit riding on Bitcoin (and have not yet diversified into any alts.)  I've seen Maxwell be uniformally out in front when it comes to trying to protect the goals of the Bitcoin project which are important to me (openness, decentralization, etc.)  When I was watching the deltas it was pretty clear to me that ~sipa was what we in the biz would call the 'principle architect' of the Bitcoin.  Adding bluematt, Back, Frie-whatever, etc into the mix makes this group clearly the tip of the codebase spear in my opinion.

It's a fair bet that some of these old timers have giant hoards of Bitcoin.  By your own logic it makes little sense that they have anything but a powerful financial incentive to foster the health of Bitcoin itself.  Since I personally believe that sidechains are by far the best hope of doing this (and benefit the world's masses in the process) I am not at all surprised and am very heartened that they have organized to achieve this effort.

As far as I'm concerned Hearn, who absolutely _has_ made some very valuable contributions to Bitcoin, has always been in direct opposition to many of the aspects of Bitcoin that appealed to me.  To his credit he has been relatively open about these things (debatable on some of them though.)  Discriminating against arbitrary users via mining consolidation, consolidation of blockchain maint to a small number of large entities, Red-listing, mainstream passport use for individual identities, etc.  I've developed a sense that Hearn has Andresen's ear in a fairly big way and significantly through the medium of the Bitcoin Foundation which also seems to align with Hearn's direction for Bitcoin.  When Gavin went to the Council on Foreign Relations (some of the most wealthy and influential people in the world) and refused to either commit to openness or even debrief on the conversations he may have had, this further damaged whatever credibility he had (to me.)

When Gavin champion an exponential growth rate for Bitcoin the first thing I thought was 'Ya, that figures.'

ETA: Considering the cost of ASIC mining equipment, storage technology would actually have to start shrinking and increasing in cost to the point that individuals couldn't afford computers before it would begin to matter to miners.

Aside from the fact that 'that don't make no kinda sense', nobody has ever really considered storage capacity (indicated by your use of the term 'shrinking') to be a factor in much of anything.  At worst one might need to physically deliver media in order to get a node operational, but that's doable.  Access to the local data for 'old school' full verification modes of operation is a somewhat different matter, but it's likely to be a solvable problem.  Both of these assume some simbalance of reasonable system growth at least.  If TPS limits were lifted completely all bets are off, but that's not what Gavin is suggesting here (for the next decade or so at least.)



The only reason those developers have "gotten behind" blocksteam is because they're getting paid to do so, they have actually included a part in their contract that states if they think the company is acting maliciously they can leave at any time, probably because they can realize what is going on already. They still work on the main Bitcoin code as well.
