i used FreeWallet.org
Please don't...

With FreeWallet, you are basically handling your coins to an unknown third-party. They don't even let you "export" your private-keys, so they are literally the only ones in control of your coins. Instead, you access your wallet with a login and password. Basically the same as using Paypal (they can block your account, freeze your funds, run with all the coins or anything else they want to do).

Hmm,,, looking at the wikipedia entry,

https://en.wikipedia.org/wiki/Freewallet

I don't find any of the developers or business names or locations.

There is an extremely brief entry in Github, almost just a placeholder. This notes that source code for the mobile versions is available via a link, and source code for the PC and MAC versions is not publicly available.

However, there is a person with a Github account,

https://github.com/jdogresorg, who maintains this low activity program set. For what that's worth.

Is there a decent business model behind this wallet? I ask this separate from a discussion of the technical merits of the wallet, many flaws of which were above described.

These wallets works the same way.
Let's look at some common wallets, and how they make money:

Blockchain.info - ads
Coinbase - exchange/ads
coinomi android wallet - ads

I made some posts already about this.
How much does an Airdrop cost?
Let's talk about privacy

These are really good discussions. I am going to merit you for each of them, thanks.

Today we are talking about the protection of user data in all scenarios, the topic is trending and there are even several projects that have been working according to the data of the users, taking advantage of the blockchain technology, the innovation, the advancement of technology, as well as solving some problems of today's world and a lot of things.
When we participate in the internet in a public way, anybody can access our data and measure us, create statistics, etc. is my knowledge when we do it public I do not have any knowledge of our private data.

I have no idea what you said there. I don't care what people are talking about or what topics are trending.

This is a very simple question. There are hundreds of crypto currency wallets available for the various platforms. In many cases they do not show a clear business model.

The lack of a clear business model creates a curiosity.

Why does this exist? Is there a business model that we don't see? What can it be?

For example, one business model could be to gather (for sale) an information list of people with holdings in crypto.

Is the product for sale You?

Is the product for sale the count of your coins?

Or is it undefined what the product might be, such that after development and deployment of a wallet, the start up can be sold to a third party. And what is his motivation?





4884  Bitcoin / Development & Technical Discussion / Re: A simple question about wallets. on: June 03, 2018, 02:36:18 AM
It's NOT CLEAR with a fair number of them what their business model is.
mostly they earn profit from ads, (exchange) affiliate commisions and value added service
Electrum with TrustedCoin charges 0.001BTC/20tx for 2FA feature, I'm not sure if Electrum gets a share of it
the rest, "a fair number of them" as you said, probably still in early phase of development created by bitcoin supporters
once they earn trust and built well-develop wallet, then they would start thinking of a business model

How is it a problem? I would say it's a decent method to monetize their wallet without compromising privacy/security.
Here's the test. Do a transaction from your app which incorporates shapeshift/changelly.

Now tell me the transactions which occurred on the blockchains.

Better, just link and put them here for discussion.
I'm not sure where you going with this, can you explain more?
afaik, using shapeshift doesn't require any identifiable personal data and only from/to addresses for asset exchange
although they are also not protecting (privacy of) their user's transactions and any related data

You are not sure where I am going with this?

It's a simple question, to show the blockchain transactions.

Otherwise you give value to someone running a click link in an app with zero audit or traceability.

Coinbase keeps a percentage. Their wallet is a straight business deal and (In my opinion) a good one for all parties.

I wouldn't call it a 'wallet'.
.....
In my opinion, this is not a wallet. It is a service. But not a wallet.

I'm good with your distinction. At the same time, we could say, "It's clear what Coinbase's business model is."

Now let's go back to various wallets.

It's NOT CLEAR with a fair number of them what their business model is.


1. Yes, apps embed shapeshifter / changelly. This has serious problems, but it is a way to provide a service and keep a small fraction, thus making a profit.

2. This thread is not about "outright scam wallets." Rather it is about the typical wallets that people download and use.

.....coinami or blockchain.info. They have a built in "currency exchange" feature where you can trade altcoins using shapeshift and/or changelly, and they make a % of the exchange fee.

And finally, yes there are many wallets out their that are scams and/or contain malware ....This is why its important to use a wallet that is open source and secure.

Much of crypto currency was done by dedicated visionaries, often without a goal of personal gain.

This is true of bitcoin. To the benefit of the world.

But what's with all the wallets? There are hundreds of wallets of various sorts, and with the exception of hardware wallets that are bought, they are all free.

What do the developers get? Why are wallets free?

Consider normal, "typical" android and IOS development. People download "free" apps. Then the developers and marketers steal your data and sell it. It's all about your data. And we all know that.

But what model of development are wallet developers following? That of dedicated shareware developers with no profit in mind? That of the current generation of "steal your private data and give you the app for free?"

What am I missing.

Most of the things these days are not free, the price is your privacy.
Your private data, your eyes catching the ads... even this forum, is not that free. Most of us are "working" here, wearing signatures, making posts to expose the ads...

These wallets works the same way.

Blockchain.info - ads
Coinbase - exchange/ads
coinomi android wallet - ads

People really do not care about their privacy. I thought that in the crypto community people would be paranoid about privacy. But most of the users here don't even know what is an adblock....

Ah, one correction.

Coinbase keeps a percentage. Their wallet is a straight business deal and (In my opinion) a good one for all parties.

...the future of Chinese megafactories.

Long term there will be no Electric cars that are not made in China; just like all other eletronics where cheap production (bare human rights and almost no environmental protection) is key.

Fuck them electric cars, LPG/CNG is where we should be heading, if we want to keep the car industry in EU/USA.  Cool

LPG/CNG is very clean and nice technology. But most people don't know anything about it, so they mindlessly repeat what they've been told was good.

The question should actually be: why do fundamentalists kill people who think different!
Because they define their own worthiness solely by what they consider unworthiness of others.

It’s pathetic i no. But we all do this in one way or another. Nobody wants to feel worthless.
Most people try to increase their worth by actually doing something meaningful.
Some (the fundamentalists) overcompensate by doing what they believe not just meaningful but epic by following their gods/leaders will. They are too stupid or blind to see that they are just exploited.

Same goes for christians too btw.

There's no need to go to extremes to try to get the word "Islam" out of the problem.

Although most people would probably agree on a term such as "radical Islamic extremists."

You have a Scripture that says jokes are not allowed?
Galatians 6:7 King James Version (KJV)
7 Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.
Mocking could be joking, or it could be insulting.

You'll have to do better than that.

No, it is not right to mock Jesus. He isn't just a character or someone famous. He is the One who came to our world to save all people. And it is not okay when people joke about this.

4893  Other / Politics & Society / Re: Why Islam kill Christians? on: May 18, 2018, 04:27:16 PM
It is very obvious that Islamic religion/ people kill many Christians all over the world. Although the Bible says, do not murder, they still practice it. What would be the reason.?
What is your proof if we Muslims are killing Christians?
Here we are Muslims with Christians joking together laughter together, why do you believe Muslims kill ka um um kristen, if indeed you have a family in killing Muslim people, then you think Muslims are killing?
You should not blame religion for that person's blame,

Here ya' go!

You sound like Obama, Soros, The EU, the Clintons, the Rothschilds, and all the others promoting global eugenics and servitude. Thankfully public opinion is resisting this at last. Brexit, the election of Donald Trump, and similar events are evidence that we may return to sanity.

I might get interested in a world gov that did nothing but have secret agents that went out on missions to take care of people and entities that wanted or worked toward world government.

....what is the point of this exercise? I believe we should be disproving that we have Bitcoins than prove that we do. Lips sealed

It's impossible to "disprove that you have Bitcoin."

That's an irrefutable hypothesis.

Like...."Disprove that guy walking down the street has a bar of gold."

Cannot be done.

Carrying this a step further, hypothetically, say in a divorce case where it was alleged by one party that the other had one bitcoin.

Wife: He's got two bitcoins! I should get one!

Husband: I have bitcoins? Can you prove that?



The court should do the same procedure it does with the thousands of offshore firms that some people use to hide the money. Demonstrate the path they have taken. At some point, fiat was transferred to an account that in exchange received BTC. This negotiation would need to be demonstrated.

Unless he has memorized the seed entirely in his head, with a search warrant and seizure, after proving the path that the negotiation made, it is quite possible that justice would have access to this portfolio containing the Bitcoins......

The chain of custody.

You would have to track the transactions down to the current address that contained the bitcoin which had been bought in the past with a fiat transfer that I made. Then you would have to show that current address had other transactions that were linked to me. Preferably both plus and minus.

And today we are urged to not reuse receive addresses. Want to guess why?
4896  Bitcoin / Development & Technical Discussion / Re: A thought experiment: PROVE you own a bitcoin on: May 18, 2018, 12:56:54 PM
I believe that once could sit down with a computer and another person, and demonstrate to his satisfaction that I have a private key that holds one bitcoin, which nobody else has access to.

This would be by creating a new private key in his presence, in some way where he does not see it or all of it.
...
But how do you prove that the key "generated" is "unique" and that no-one else has access to it? Huh

I know it's a bit of a stupid argument really, because proving the absence of something is always difficult... but just because they see you "generate" it... doesn't mean that someone else doesn't have access. Although given that this is a "thought experiment" and therefore we're free to dream up all sorts of theoretical scenarios... I suppose if you were both in a sealed room with dice and an offline device that could convert the dice rolls to private key/public key/address, you could be fairly certain the key you generated is "unique"... So as long as the other person had no access to a transmitting device, you could send 1 BTC to the address... show the confirmation and they could be fairly certain you had sole access to that 1 BTC at that point in time... and you wouldn't have to worry about them stealing it as they have no way of "using" the private key.

The problem then would be that to ensure they don't steal your 1 BTC, you either have to leave them in the sealed room forever, kill them... or move the 1 BTC to another address. At which point, they can no longer be certain you have sole access Tongue

Yes this is all correct. RE the bolded above, an example would be if the key I presented was part of a heuristic chain, for which another party had knowledge of.

This reminds me of playing cards, where in normal conditions one assumes that a party other than the dealer cuts the deck, and randomness is established. That's knowing that cutting the deck is insufficient if a talented mechanic is the dealer.

Suppose that I generated a private key, and then allowed the other party to see and to change ten digits of it. He can be certain its then secure from 3rd parties at that moment. I then generate a public key, and show that it contains zero. Then I put this private key in my wallet, move a bitcoin to it.

You mentioned, "The problem then would be that to ensure they don't steal your 1 BTC, you either have to leave them in the sealed room forever, kill them... "

That's kind of funny. "Okay now I've proved I have one bitcoin, but you have to die..." It's like the joke about the spy who says "If you find the secret I'll have to kill you."

But the other party, in the above scenario, does not know the key, only ten digits of it. He cannot find it from just ten digits.

4898  Bitcoin / Development & Technical Discussion / Re: A thought experiment: PROVE you own a bitcoin on: May 17, 2018, 09:39:59 PM
It's impossible to prove ownership without some out of band mechanism because the only relationship maintained by bitcoin network is between bitcoin and (pub/pri) keys. There is no way to tie an id to a key. Even when someone can move bitcoin or sign a message with private key, it still doesn't prove ownership. He can simple ask the owner of the key to do these operations for him.

I believe that once could sit down with a computer and another person, and demonstrate to his satisfaction that I have a private key that holds one bitcoin, which nobody else has access to.

This would be by creating a new private key in his presence, in some way where he does not see it or all of it.

Then I would show that I was able to move one bitcoin to the public key of that  address.

Then sign a message from that private key and send it.

But if the other party was not in the same room, but was across the internet, then the proof seems far less certain.
4899  Bitcoin / Development & Technical Discussion / Re: A thought experiment: PROVE you own a bitcoin on: May 16, 2018, 06:19:52 PM
If you want proof of "I can spend coins associated with this address", you can sign a message with the address (or specifically with the private key whose public key hashes to the hash encoded by an address).

This is insufficient.

It requires more than simply "any signed message".  The mesage MUST be phrased in such a way that it is extremely unlikely that someone else could be tricked or convinced into signing the message for the person claiming to hold the bitcoins"

If Spendulus has 1 BTC and achow101 has 0 BTC, but is telling me that he has 1 BTC, then Achow101 could trick Spendulus into signing a message that says:
Code:
As of 2018-05-16 this address contains at least 1 BTC

Then Achow101 could forward to me the message that Spendulus has signed.


Furthermore, a signed message only demonstrates that you are ONE of the people that have access to the bitcoins.  It does not prove that you have SOLE access.

I don't think there is ANY way to prove that nobody else has access to the coins.




C does not require trust, does it?

It does.

I must trust that you aren't asking someone else to move that bitcoin on your behalf.

I had noticed that when a pre existing private key was in use, there is no recorded history of it's having single or multiple users or "owners." The phrase "no recorded history" is meaningful, because now we must rely on trust.

Hence it appears that any means of proving ownership of a bitcoin must involve  the creation of a new private key.

A wishes to buy something from B with 1 bitcoin, and B asks for proof.

A sits down with B and tries various ways to prove he has coins.

Maybe he logs into Coinbase and shows B the screen.
B raises the objections listed above....

Maybe the answer is something like this.

"Yeah my wife also has access to the account but she also has access to our credit cards and bank accounts. So what? If you had verified those you verified the presence of funds at that instant and you didn't care about multiple people having access to them. Why are you demanding a higher standard here?"
4900  Bitcoin / Development & Technical Discussion / Re: A thought experiment: PROVE you own a bitcoin on: May 16, 2018, 11:41:37 AM
I don't have bitcoins. I am simply able to control and use the private keys associated to my UTXOs that give me the opportunity to transfer thouse outputs onto other addresses that will become new UTXOs for the next guy on the blockchain.
Again, I have NO bitcoins. I HOLD keys Wink

This is an important distinction, but in the context of the question, the problem simply shifts to "Prove you hold keys."

Like, "Dude. If you think I'll drive 50 miles to trade my riding lawnmower for your bitcoins, you gonna have to show me you have them first."
