Who dont know or had used paypal before?Paypal has regulamentacion and is accepted everywhere and is a company with a long history record

Banks also have regulamentation and they're companies with long track records.

with paypal you are also safe, when you do tranzaction online easy can chargeback

Is chargeback safe?

so what's with this Jamie Dimon guy.

I keep hearing him in the news discrediting Bitcoin.

James "Jamie" Dimon is an American business executive. He is chairman, president and chief executive officer of JPMorgan Chase

I've read enough. His opinion is irrelevant.

PayPal is good making their users feel safe just like banks are good making their users feel safe. They use a honesty mask and make themselves look like an impenetrable vault and regular people believe in them because we were all educated to do so.

Bitcoin's acceptance isn't being hindered by block size issues. When people first get to know and start using Bitcoin, they might not even know what a block is. People will only get to know these issues with Bitcoin if they start using it and investigate the currency, at which point they're probably already actively using Bitcoin in their lives.

The biggest issue is, as said, low merchant acceptance.

Virtual currencies will kill PayPal and fiat. However, Bitcoin might not be that currency, and we might not be here to witness that.

Why not Bitcoin? Bitcoin + Lightning Network is the real Paypal killer. Until then we will possibly remain rather small, but that is actually good news since it only means we have more time to benefit from being there before the average joe jumps in. We are still early adopters. There will be no excuse to not accept BTC once LN is working. It will faster and cheapter than anything else.

It can be Bitcoin, I only stated that it might not be Bitcoin Smiley I don't see Bitcoin being ready for prime time straight away with whatever change it may have this year.

We're delusional if we all think we're early adopters. Not even all Legendary users from this forum are early adopters. At least that's what I think.

Bitcoin is already faster and cheaper. We don't exactly need LN or block size increase for that, especially the cheaper part (pretty hard to be even more expensive than PayPal!!)

There's an Armory board on the forums. Issues related to that software should be posted there.

I didn't quite understood your question, are you trying to say Armory takes a lot of time to organize the blockchain? It does, especially if you have older hardware. Are you syncing your blockchain from scratch?

This didn't help?

Quote
However, you can use the rpc call setaccount to change the account associated with the address. The first argument to setaccount should the the address you're changing; the second shound be the account you're moving it to. (If you want to move it to the default account, put "" as the second argument.)

Note that this does not change the balance of the account; balances are tracked internally. If you want to keep this consistent, run getreceivedbyaddress, then move that balance to the new account.

You can also use PyWallet to delete addresses permanently. Use the --multidelete option, and pass it a path to a file. That file should contain key as the first line, followed by each address you want to delete, each on a new line.
1567  Bitcoin / Electrum / Re: Difference between sweeping private keys and simply sending btc? on: January 20, 2016, 10:04:24 PM
Ok thanks.

I just set up a cold storage wallet on an offline computer and a watching only wallet on my online computer.

I want to send everything from my blockchain wallet to my electrum wallet. Should I just send the full amount instead of sweeping?

I notice I can only sweep from the offline wallet. What's the process if I sweeped?

Do I have to do the transaction thing as outlined here? http://docs.electrum.org/en/latest/coldstorage.html

Finally, is there a way to get the cold storage wallet to show the correct balance?

I sent a small amount of btc to the watching only wallet so it shows a balance but since the offline computer has no way of knowing this, it doesn't show any transaction history or balance.

Sorry lot of questions. I read the documentation but it doesn't really have a lot of detailed instructions for cold storage.

You can just send, it's probably easier to do so from an online wallet, and the option to sweep on Electrum is greyed out when using a watch only copy.

The website you referred is explaining how to create a transaction on the online computer, sign it on the offline one and broadcast it on the online one, doesn't really apply to sweeping.

The cold storage wallet cannot show you a balance, obviously, otherwise it wouldn't be cold storage.
1568  Bitcoin / Electrum / Re: Difference between sweeping private keys and simply sending btc? on: January 20, 2016, 08:52:48 PM
Sweeping is using your private key on another client and sending all the coins on that key to another address, while just sending the coins doesn't require you to export your private keys.

The end result of just sending the coins or sweeping is the same, the difference being in exposing the private key while sweeping and exposing your password while sending.

Full article:

Quote
Now that Satoshi is a “Davos man”, does that make him “The Man”?




Soz disrupters. Seems you’ve been co-opted. The powers that be know there’s nothing like the offer of an evening out sipping cocktails with Leonardo DiCaprio and Kevin Spacey at the Piano Bar to get you to abandon all your high falutin’ values about disrupting the world hierarchy system.

Indeed, the day the Davos elite shower you with love is the day you’re officially no longer cool. More to the point… “A single ledger to rule them all? Why Satoshi, it’s what we’ve always wanted!”

It’s all so wonderfully circular.

Boy meets disruptive network technology protocol. Boy becomes infatuated with disruptive network technology protocol. Boy invests at least three years worth of savings in a life together with the protocol. Protocol becomes power needy. Protocol gets concentrated in the hands of a few. Boy has heart broken when protocol runs off with the banking elite. Boy resents protocol for having stolen his heart in the first place. Boy pledges to never love again…

On the streets of Davos this year there are only three discussions being had. One: robots are going to take over our jobs. Two: blockchain is amazeballs and three: fintech is like blockchain amazeballs, but with even more possibilities to control and mould the behaviours of the common man.

To be fair, privacy, cyber security and the general shift in international power politics are also on the agenda. And there’s even some discussion on the downsides of associated with virtual currency amazeballs technology as well.

To wit, here’s the press blurb from the latest IMF paper on virtual currencies, cited by Christine Lagarde during the “Transformation of Finance” panel on Wednesday.

Quote
Virtual currencies (VCs) and especially their underlying technologies are a potentially important advance for the financial sector that could increase efficiency and financial inclusion, but can also serve as vehicles for money laundering, terrorism financing, and tax evasion. Achieving a balanced regulatory framework that guards against risks without suffocating innovation is a challenge that will require extensive international cooperation, says a new staff paper, “Virtual Currencies and Beyond: Initial Considerations,” released today by the International Monetary Fund (IMF) during the World Economic Forum.

And skipping over to the paper’s conclusion:

Quote
A key conclusion of the paper is that the distributed ledger concept has the potential to change finance by reducing costs and allowing for deeper financial inclusion in the longer run. This could be especially important for remittances, where transaction costs can be high, around 8 percent. Distributed ledgers can also shorten the time required to settle securities transactions, which currently take up to three days, as well as lower counterparty and settlement risks.

As we’ve noted many times before on this blog, we’re not really convinced by the cost assertion. It seems imprudent to make such claims without there yet being viable proof of a working private blockchain anywhere in existence and the nearest candidate, the Bitcoin blockchain, encountering ever greater cost and scaling challenges by the day. Furthermore, totally ignored by the paper, is the fact that all blockchains have thus far been subsidised by one sided capital inflows whether that’s through funding rounds or speculative investors. Eventually those investors will want returns, or at a minimum the protection of par value. The jury’s still out on whether they’ll get that.

There is, however, one justifiable rationale for wanting a clunkier, less efficient and costlier clearing process.

The biggest open secret of the financial world right now is the ticking time bomb which is the digital banking system we’ve created in terms of security and fraud control. We’ve all grown accustomed to our digital bank accounts and how easy it’s made our lives, but the truth is they’ve made fraud incrementally easier as well, and it’s this risk which is now eating away at the system’s core.

Blockchain, being fundamentally a cartel enforcement system, is appealing to banks for such fraud control reasons. Not only does it theoretically make it costlier for random hackers or intruders to cheat the banking system, it makes it costlier for banks to cheat each other as well. That’s the genuine insight of blockchain. If you make it so prohibitively expensive to clear a fraudulent transaction (equivalent to the cost of fixing a political election) that it’s beyond the scope of Tom, Dick or Harry to attempt it, you significantly increase the security of the system.

But there is a catch. Banks know that forging a cartel as strong as that eliminates all possibility of out competing with each other in terms of risk, screening and security. As far as they’re concerned, they become one bank (with all the non-diversity risk that comes with monopoly systems). It also means erroneous transactions become nigh impossible to reverse, money supply becomes a constant and scaling is compromised completely. Hence the rage for private blockchains with the promise to provide banks with override options within their special trusted network.

But as we overheard in one of the shuttle buses at Davos — from a very authoritative looking man in a furry hat — “there’s no-one you can’t bribe”, meaning as soon as there’s a backdoor anywhere in the system, it becomes as game-able as ever. You’d think Davos delegates, who spend a lot of their time queueing to get in and out of trusted zones, would understand this. You’re only ever as secure as the corruption potential of your lowliest employee.

As for encrypting something so securely you yourself can’t even access it… well, you see the problem with that. It’s like putting something in a safe space and then forgetting where that space was. A common problem for pirates back in the day. And a common problem for bitcoiners today. Hence all the “distributed” clues. Hence all the Treasure maps. Hence all the secret keys.

But we digress.

The IMF’s report says distributed ledger technologies may have the potential to change finance by reducing costs and allowing for wider financial inclusion… but here’s another thought.

Perhaps payments systems are largely irrelevant when it comes to financial inclusion, a euphemism for “dealing with the poor”. Perhaps the real problem is that the financially excluded tend not to have fixed abodes, fixed addresses or any private wealth stakes to call their own? Nor, for that matter, do they have the capacity to create wealth because you know, the wealth-creating robots are owned by the elite, who for some reason don’t feel compelled to set them on “create houses for the poor for free” mode. Furthermore, if and when the poor do find themselves with the capacity to work, perhaps the real problem is that they can’t stop the wealth they create being misappropriated because their jurisdictions lack the legal and defence structures which are necessary to protect them?

In that regard, here’s a MUST READ paper published last December by Ernesto Dal Bó, Pablo Hernández and Sebastián Mazzuca on the paradox of prosperity and security, and the role in particular played in civilisation making by both surplus and defence.

As the authors note about the key to prosperity:

Quote
….that initial productivity be high in terms of its purchasing power over improvements in defense capability. The possibility of accumulating means of defense helps create the conditions where productive investments can be made without triggering predatory challenges. This result may also help rationalize historical experiences where a temporary economic boom allows the state to consolidate its power and usher in a phase of more sustained growth. Isolating formally the pivotal role of defense capability to the civilizational process contributes to the demanding enterprise of discerning how economic shocks can hinder or help state formation and political stability more generally.

The takeaway: try not to get so rich that greedy predators notice you have something to take. If you do, don’t lower the barriers of entry to your wealth too far by under spending on defence, but by the same measure don’t overspend your resources on battlements either or they’ll be nothing left to protect.

Funny to see banks so interested in blockchains... Smiley

just wondering if anyone knows what the transaction times are these days.

They're instant, like they've always been.

I sent a small amount if bitcoin a few months ago and it went through pretty fast. Now I sent one today and just shows unconfirmed in  blockchain.info and 0% .  Is this just me and today or is this normal now ?

The inputs are small or you included a small fee.

1573  Bitcoin / Development & Technical Discussion / Re: What's the difference between a normal wallet and a node? on: January 19, 2016, 12:26:58 AM
Bitcoin Core is the software. Core can work as a Wallet and/or a Node. Same software, two different functionality that can work at the same time, or not. Does this answer your question?

I don't think there's a way to limit bandwidth usage in Core, you'd have to do that at the system level I think.

What settings do you have to alter to make Core work as a Node? I know wallets and nodes operate differently, and that you need to open port 8333 to let your node get more than 8 connections to other nodes, but there must be more settings that need changing. Otherwise everyone' wallet would operate as a node.

None, Core has the ability to work as a node straight out of the box. Everyone's wallet is a node, you just have to forward the right port and you're contributing.
1574  Bitcoin / Development & Technical Discussion / Re: RBF transactions to be enabled at the next core update on: January 19, 2016, 12:24:47 AM
So this means that when a transaction is broadcasted it has a flag saying that RBF can be enabled, or that it can't?

If all of the inputs of a transaction have nSequence = UINT_MAX or UINT_MAX-1, then they have RBF disabled. Sending transactions with nSequence = UINT_MAX is the default for ~all wallets.

Thank you, I was not aware of that.

You are free to start your own altcoin based on Bitcoin's blockchain, blacklisting the coins you wish to blacklist.

And in fact many people have tried it and still are trying.


Could you link to such attempts? It would be interesting to see Smiley

Folks attempting to do this can't complain about having less users than Bitcoin.

1578  Bitcoin / Wallet software / Re: GreenAddress (Droid) vs. BreadWallet (iOS) payment verification. Decentralized? on: January 18, 2016, 11:22:05 PM
You need to have a login on GreenAddress (and that's a big no no, at least for me), so they do use some kind of private servers for their app to work. breadwallet seems definitely more decentralized or at least more in favor of privacy.

But anyways, I'm a bit biased, as I'm a big fan and user of breadwallet Smiley So take this with a grain of salt. Test both apps and see which one you like best.
1579  Bitcoin / Development & Technical Discussion / Re: RBF transactions to be enabled at the next core update on: January 18, 2016, 11:17:36 PM
My limited understanding is that the first transaction needs to raise a flag in order to allow RBF. Merchants that accept 0-conf TX could scan for the flag and wait to deliver their part if it is set. On the other hand I am not sure how ready merchants or even regular wallet implementations are.

Can anyone tell the major benefits of this update apart from what I understand is to help induce a free market for transaction fees.  Won't it break the ability to accept zero confirmation transactions? 
Nope. Those transactions are opt-in, meaning that if the transaction doesn't opt-in to use RBF, then it can't be Replaced later.

So this means that when a transaction is broadcasted it has a flag saying that RBF can be enabled, or that it can't?
