1061  Bitcoin / Project Development / Re: Frog: Bring Bitmessage mainstream! on: June 29, 2013, 12:06:21 AM
 Email with PGP is already ridiculously easy to use, works with existing infrastructure and has been PROVEN to be secure.

 -bm

It seems like Bitmessage won't become wildly popular unless we can make it ridiculously easy to use.
Frog will solve this by being a very easy to use Bitmessage client for the web.

How will Frog work?
Frog will function very similarly to the Electrum Bitcoin client. The user's client reads data from the network off of a pool of servers.
When you open the Frog application in your browser, it automatically connects to an available Frog server that runs the complete Bitmessage software. When you send a message, your browser completes the proof-of-work necessary for propagation, and sends it to a Frog node. Then, the Frog node follows the standard protocol to send the message to the Bitmessage network.

But, wouldn't this decrease decentralization?
Not really. Since the birth of Electrum, the community has put up dozens of servers for the client to use. This has resulted in the creation of reliable supernodes that benefit the entire Bitcoin network.

Just like Electrum, anyone can put up a Frog server for the clients to use. So the servers will not be controlled by a centralized authority. Also, since a proof-of-work is required for sending Bitmessages, attacking these servers will be very difficult. Frog nodes will have all the protections a regular Bitmessage node has. So Frog will result in the creation of supernodes, which will help the entire Bitmessage network

Will it be open source?
Yes.

What's your timeline?
I am currently on my summer vacation and have a lot of free time on my hands. I estimate having a funtional beta by August.

Frog will help conquer surveillance by putting great tools into more hands. Help us make it a reality.

Funding successful, and work begun a while ago!


Here is my GitHub, and a dev blog will be up as soon.

there was a period of American history where the Federal Government did not regulate banking.

http://en.wikipedia.org/wiki/Wildcat_banking

Quote
Wildcat banking refers to the unusual practices of banks chartered under state law during the periods of non-federally regulated state banking between 1816 and 1863 in the United States, also known as the Free Banking Era. This era, commonly described as an example of free banking, was not a period of true free banking, as banks were free of only federal regulation; banking was regulated by the states. The actual regulation of banking during this period varied from state to state.

Jefferson was against central banking, but Andrew Jackson was perhaps the strongest opponent of a federal bank during that period.

If a person buys or sells bitcoins for dollars, they are supposed to register as a Money Transmitter. This is being applied to the average person even Foundations that do not angage in this, based on the associations of their members.

So, I propose nobody ever buys or sells bitcoins for dollars anymore. I propose we give them away for FREE whenever someone buys or sells a piece of blank paper, valued at approx the same price as bitcoins.

If someone is willing to buy my "pet rock" for $105.00, I'll include a FREE Bitcoin!





what if you trade them for gold?

1067  Bitcoin / Development & Technical Discussion / Transaction Signature ... Simplified Transaction? on: June 27, 2013, 02:07:56 AM
Hi All,

  I've been looking closer at the TX verification mechanism.

  in the Wiki we have : "The other component is an ECDSA signature over a hash of a simplified version of the transaction."

    https://en.bitcoin.it/wiki/Transactions

  Can anyone explain 'simplified version of the transaction'?  Is this explained in detail anywhere?

  I took a look at Mike Hearn's code (com.google.bitcoin.core.Transaction [1] ) and I suppose I could reverse engineer, but that would take more time than reading over some documentation.  It seems that the signature is of a subset of the transaction, how exactly this works is not altogether clear to me.

  pointers?

thanks -bm

Until there are at least a few local economies using Bitcoin amongst themselves, Bitcoin will remain primarily a toy for speculators and, yes, zealots and criminals.  That's just how currencies work.

who is going to invest in a currency that can be produced out of thin air by anyone with a computer?

 Personally I believe they are trying to create legal barriers from exiting the failing USD.

 They won't be successful in the long run.
1070  Bitcoin / Bitcoin Discussion / Re: Zealots and Criminals, Is no one using bitcoin for legitimate purchases? on: June 26, 2013, 09:28:14 AM

It was Paypal President David Marcus that said "The big question is whether [Bitcoin] is going to go mainstream or stay limited to just a few zealots and criminals." I started my bitcoin business, stampbit.com, with the intention of finding out for myself. Its been two months since i have started and have seen very little interest for this bitcoin version of USPS click'n'ship. No its not instant like clicknship, nor can i reasonably compete with my supplier on price, but then again i am trying to provide something that may prove inaccessible to anyone without a paypal account or credit card, and do it in a way thats much more convenient that how USPS does.

But you'd think after two months i'd get the hint, no one cares! Yet i realized it was not only me when i stumbled upon bitcoinstore.com who so generously posts their sales figures in order to urge buyers to take the initiative and support bitcoin by allowing them to remain competitive. For these last two months ive seen these figures climb at a snails pace, in line with my own business. So maybe by business was just a bad idea, but what about bitcoinstores? Their prices are CHEAPER than its competitors newegg and BHPhoto! And they have all the same features as their competitors. Its only shortfall is that its selection is not as vast, but for a new businesses its selection is quite generous. So why then is bitcoinstore not beating them?  

  • Price fluxations put all the risk on buyers.
  • No one wants to take any risk when they have cheap, easy, safe, fiat.

And how do we create that price stability?

  • E-commerce.


and how do we do E-Commerce?  by offering insurance and reversibility on transactions, ie. legal tender.  In other words 'FIAT'.

maybe bitcoin people should venture out of their houses once in a while?

now what sort of person doesn't have a paypal account or credit card?

either 1) very poor people. 2) criminals who don't want to divulge their identity.  can you think of anyone else?  if so please let us know.

1073  Bitcoin / Bitcoin Discussion / Re: 512-qubit Quantum Computer acquired, is bitcoin doomed? on: June 24, 2013, 06:44:02 PM
Unless D-Wave has changed their direction in the last 5 years (the last time I checked in with their progress), nothing they are doing actually constitutes a "real quantum computer".  When I say "real," I mean one of those quantum computers that actually leverages quantum interference to solve problems, which could be used to break not just Bitcoin cryptography, but all the cryptography on which the internet is based.  If this was a real problem, you can be sure that alarm bells would be ringing around the world, and for much more than just Bitcoin.  

Real quantum computers aren't just faster -- they solve problems differently.  Shor's algorithm takes integer factorization from O(ecuberoot(N)) on a classical computer to O(N2) on a quantum computer.  This isn't just faster -- this makes a whole class of essentially-unsolvable problems, solvable (including the discrete logarithm problem on which Bitcoin crypto is based).  

Yes, you can get a speedup on pure-guessing problems using Grover's algorithm -- from O(2N) to O(2N/2).  That's a unique capability that QCs can exploit, but the least interesting in terms of breaking cryptosystems.  Most crypto systems use key sizes big enough that even if you halved the keysize, it would still be secure.  And the defense is to just double your keysizes, once, and the problem goes away.  But not with Shor's algorithm -- the whole class of problems is compromised.

D-Wave has always been a joke in the world of QCs.  What they are doing is cool, and they may be developing technology that is somewhat related to QCs, but they shouldn't be using the phrase "Quantum Computing" in their product name, because that terms is reserved for a whole new class of computing systems, not classical computers that use quantum bits to do things classically faster.

etotheipi, an article I just ran into that reflects your comments here : http://www.scottaaronson.com/blog/?p=1400

It's true that when you cross over into the commercial arena, you typically encounter disjoints between promises and reality.  Whenever you get enough public interest in some scientific idea, eg. Quantum Computing, someone will claim to be delivering it despite it being impossible.

There are projects being advertised right here in this forum, that claim even to be Open Source, that don't even come close to living up to the claims made about it.

1076  Bitcoin / Development & Technical Discussion / Re: which address will get the money in multisig? on: June 24, 2013, 03:11:07 AM
Seems a lot of people don't understand what a multisig transaction is.

It requires 2+ crypto keys to unlock the transaction and the output can then be put into any address the owners of those two keys wish.

as far as I know, no wallets will show this particular transaction as part of the balance for either address.

so in that sense, it's in a special JOINT ACCOUNT.  It might be possible to make a special kind of wallet app that can show the balance of such a joint account(perhaps one already exists), however this balance cannot be spent without BOTH private keys.
