521  Bitcoin / Development & Technical Discussion / Re: Is there any full node implementation 100% compatible with the core client? on: January 14, 2015, 02:34:57 PM
It wouldn't be the most shocking thing; but enormous effort goes into preventing it.
Which is equally true for alternate implementations.

Since it's not possible for any implementation of Bitcoin to prove perfect compatibility with own present and past versions, treating any single implementation as special is incorrect.

They're all alternate implementations.
522  Bitcoin / Development & Technical Discussion / Re: Is there any full node implementation 100% compatible with the core client? on: January 14, 2015, 06:01:54 AM
Compatible in what way? RPC, P2P, consensus code?
consensus code

OK. Lets try "exception method".
What are the implementations which are not 100% compatible?
All of them, including Bitcoin Core.
523  Economy / Speculation / Re: The bitcoin price crashes - here's why on: January 14, 2015, 04:00:08 AM
Bitcoin is crashing because the liquidity of USD is dramatically worsen since the stop of QE3, now every raw material and other foreign currencies are going down together with bitcoin, spare assets are being sold out in exchange for USD because there is no 2.8 billion USD trickle down from FED every day
Exactly so.

Right now Bitcoin is shedding the speculative adopters because for them it makes more sense to hold USD while the debt singularity is busy devouring Dollar liquidity.

While this continues Bitcoin will see organic adoption rather than speculative adoption.

The organic adopters are were already in the informal economy, and those who get pushed into the informal economy due to the effects of USD appreciation.

Sooner or later, appreciation of the USD is going to cause financial distress for indebted Americans (statistically speaking, all Americans). As more people get pushed over the edge and end up facing the gamut of civil judgements and their associated wage and bank account garnishments, the fraction of people who need Bitcoin's censorship resistance will increase.

Someone who's facing a 100% garnishment of what little money they have in the bank would do better to have all of that value in Bitcoin, even if there's a potential 90% downside risk. Keeping 10% is better than keeping 0%.

The last time we saw this kind of mass financial distress was 2008, and just like we saw then people will adapt to financial distress by joining the informal economy.

The major difference between now and then is that "cash under the table" income is no longer an option that's restricted to blue collar labor.

The ability to get paid by clients anywhere in the world without moving funds through the banking system means that tens of millions of middle class professionals now have the same opportunity. In fact, the are arguably in an even better position because anyone who produces digital deliverables can now access a global client base.

Perhaps he should stick with "the real Bitcoin" from before the hard fork that created the 1 MB limit.
Hilarious how many people defend the 1 MB limit without realizing that it wasn't part of the original release.
525  Bitcoin / Armory / Re: Armory 0.93 testing release! (with 0.05 BTC bug bounty) on: January 10, 2015, 03:04:31 AM

   - Supernode Mode
        Use the "--supernode" flag before creating the databases to create
        a supernode database that enables instant address & wallet import.
        This is an enabling feature for high-volume, consumer facing apps
        and services to be built on Armory, such as exchanges and block-
        explorers.  NOTE: Running with --supernode will result in an Armory
        database approximately double the size of the blockchain!


It would be nice to have the option to configure this in the Settings page, as well as --skip--announce-check.

As someone who I don't like quoting said, "Bitcoin has become the universal bug bounty."
527  Economy / Speculation / Re: sidechains discussion on: January 06, 2015, 07:54:28 PM
(such as including the economic value of a block's transactions in addition to difficulty, this would lower the height/priority of chains that do not include all the transactions that honest miners are including)
That doesn't sounds like a very good idea.

You've just described turning Bitcoin into a proof of stake system.
528  Bitcoin / Development & Technical Discussion / Re: Cold storage and bad RNG on: January 06, 2015, 07:50:10 PM
Thanks, NSA.

I'm sure it's been handy for ECDSA to be vulnerable to leaking private keys every time there's a signing event, and also to leak private private keys through variable-time operations.
529  Bitcoin / Development & Technical Discussion / Re: Cold storage and bad RNG on: January 06, 2015, 07:40:08 PM
this is a deterministic operation there is no RNG involved
Until very recently, this was not true for any Bitcoin clients.

The common way of performing ECDSA signatures requires 256 bits of new entropy for every signature, and if you get it wrong it's possible to reveal your private key.
530  Bitcoin / Development & Technical Discussion / Re: Cold storage and bad RNG on: January 06, 2015, 04:18:40 PM
If your key creation RNG is bad, of course you don't ever have to spend to lose your funds.
There are implementations out there getting the initial key creation wrong too, not just signing?
531  Bitcoin / Development & Technical Discussion / Re: Cold storage and bad RNG on: January 06, 2015, 01:40:16 AM
I wonder if it is something widely known that if you have a bad RNG - then the attacker can empty your cold storage as easy as hot wallets. It is kind of obvious - but when listening to all these talk about 'coins secure in cold storage' I had the feeling that people don't realize this.
Only if people are reusing cold storage addresses .

I guess that applies to people using paper wallets, which is another reason those things were bad ideas from the beginning.

What can she actually do, though?
535  Economy / Speculation / Re: Gold collapsing. Bitcoin UP. on: January 05, 2015, 09:42:05 PM
Rates will have to rise and after a few raises we will finally see more qe and final collapse of trust
The consequences of resuming QE are unaccceptable.

So are the consequences of not resuming QE.

Must be fun to be in any kind of decision-making position at the Federal Reserve right now.

The USD desperately wants to appreciate.

The reason the USD lost so much value over the last century was due, not to base money printing, but to credit expansion, a.k.a debt issuance.

Debt is temporary. It's either repaid, or else defaulted. Either way of resolving debt shrinks the money supply as much as the original issuance expanded it.

As long as the population was growing, and as long as the middle class had positive savings, it was possible to expand credit. Now both conditions are no longer true.

Since it's no longer possible to continue credit expansion, the only way to stop the deflation caused by debt repayment and defaults is to print more base money (QE).

When QE stops, the USD resumes its natural appreciation.

If it requires more resources to run a full-node, less full-nodes will be run (all other variables held constant).
This is an effect of shitty network design.

Satoshi was right to realize that a currency should have a limited supply, but that doesn't mean he was right about (or even though about) the economic features of the rest of the software stack.

With a tiny handful of exceptions, all P2P networks are economically broken.

Consider a McDonalds restaurant. The more customers they need to serve, the more resources they require to do so.

Yet in spite of that fact, as the customer demand for McDonald's product increases, so does the number of stores!

Why is that the opposite of what happens with P2P networks? Because in the case of Big Macs, people pay for what they use. This customer action of paying for what they concume means that McDonalds doesn't really need to worry about how it will gather the resources it needs to scale.

The Satoshi Social Contract requires that certain system-level constraints exist (for example, the inflation schedule….we can't have the free-market solve that problem).
That's an objection only brought up by people who don't understand money.

The reason the inflation schedule shouldn't change is the same reason you shouldn't put an anchor on an airplane.

In a way, the free market *does* solve that question though - because people are free to choose whether or not they want to travel in a boat or in an airplane.

Another requirement is that Bitcoin remain decentralized.  Without a constraint on blockchain growth, it seems less likely that this would always be the case.
Let's talk more about this requirement after you produce a workable definition of what "decentralized" means, and the arguments you use to justify your conclusion about how different situations will affect it.
538  Economy / Speculation / Re: sidechains discussion on: January 05, 2015, 05:13:07 PM
It is the particular approach to sharding that makes it less secure, to reduce bandwidth.

I agree that sharding reduces security. I wouldn't propose sharding the blockchain as a scapability solution.[/quote]

That if your home computer had to do 2.25TB/day down to be a full node you might not be able to do it, which is a centralising factor.

You're saying that retaining the possibility for home computers to be full nodes is both necessary and desirable.

I understand that many people have made this claim over the years, but I am not aware of any attempts to actually prove either of those.

One of the problematic implicit assumptions I can identify in that claim is that if home users can't run nodes, the number of total nodes in the network would decrease.

Why would anyone assume that in a future Bitcoin economy that generated 100k tps of demand would not fewer business users running full nodes then than home users running full nodes today?
539  Economy / Speculation / Re: sidechains discussion on: January 04, 2015, 09:55:56 PM
I said what on the thread that you trimmed Smiley  security...
I though you meant one particular method of doing 100k tps was insecure, not the mere fact of achieving that rate.

Can you explain what about higher transaction rates inherently makes the blockchain less secure?

Seems he does not understand what is "100k TPS".

100,000 transactions * 260 bytes * 60 seconds * 60 minutes * 24 hours = 2 246 400 000 000 bytes per day  =  2.25 TB / day
Yes, I can do math.

So 100k TPS means 2.25 TB / day of transaction data.

What's your point?

Some bizarre form of Tourette Syndrome
If you have trouble understanding how businesses survive the economic reality that competition in a free market reduces the profitability of all ventures over time, then maybe you can go ask them for yourself how they manage to deal with it?

There are millions of them in the world, so it shouldn't be too hard to find a few and talk with them.

Let us know how your investigation goes.
