Assuming that no protocol changes to transactions happens and no one has spent those inputs yet, then that transaction can be broadcast whenever you want. There is no timestamp and the time is not a part of the transaction unless you include a locktime.

You could ask him to try using a multisig escrow. You can deposit into that address and he would know that you can't access the coins. Then after you are done your stay there, you can deposit the remaining into the address and release the Bitcoin to him. I would recommend that you either find someone on this forum for that or use keyscrow.com for it.

What do you mean by "based on the Bitcoin protocol"? I don't quite understand that. Can you go into details on how the DVPN uses Bitcoin to become distributed.

Also, why do you store the credentials on the blockchain and have them change instead of making this network something open to the public that does not require authentication? Something like Tor?

Lastly how does this protect my privacy? Does your network route my data through three different VPNs before it reaches its destination like Tor does? It seems like the only privacy is the data is going through 1 VPN before its destination which opens up the whole thing to privacy and Man-In-The-Middle attacks. That 1 VPN could be malicious and it would know who the user is and where he is going. How do you solve this?

Found a seller. Closing this thread.

Interesting. I haven't seen any around me but maybe that's because I'm not looking hard enough. Are there any accurate maps with all of the places that accept Bitcoin?

Since Bitcoin Core puts a heavy load on the processor and network, it could be drawing too much power and causing the power supply to fail. Try using a power supply with higher amperage and higher quality.

I would like to buy a Kerbal Space Program Steam gift for $35. That is .
Please PM or reply if you are interested. Escrow if needed but you will need to find an escrow and pay any fees.

Buy a few thousand bucks of ASIC hardware. That doesn't fit into your budget of 0. Your best option is to look around in the services sub forum and see if there is anything that you are able to do that someone will pay you for. That is a fast way to earn some Bitcoin without any initial monetary investment. You can also look for sig campaigns but most won't accept newbies. You can also buy a higher level account and use that in a sig campaign but that requires that you have Bitcoin to begin with.

Really? Do they accept Bitcoin or are you doing that with a Bitcoin Debit Card like Bit-x?

Yes. If someone from a state can go onto your website and exchange Bitcoin for fiat, then you are operating in that state. You will either need to get several licenses, or prevent users from states where you are not licensed from registering or doing anything.

I don't think you will need a license if no fiat at all is every involved. However, you should still consult a lawyer as the information that you get on this forum might not be correct.

Normal money. Stuff that governments issue e.g. USD, GBP, etc.

I think it will take a lot of time and cost at least 100 USD and the laws also vary state by state. I think you will need to get a license for all states that you want to operate in. If you offer your service to a particular state, then you must get the license for that state.

If you plan on doing this, I would advise you to get a lawyer who knows what he is doing.

Tor is not foolproof, but it is constantly improved.

The three articles Blazin8888 posted have been fixed and have been fixed for a very long time. Tor has been modified so that it will always use https so the exit nodes can't snoop. It has modifications that warn of html5 canvasing and javascript. It blocks javascript from running. Running Tor with default settings is quite secure. It only becomes insecure when users decide to mess around and change things for their convenience.

Of Course, it is vulnerable to traffic analysis. So is every other network in the world. It can be prevented and people are working on it.

What I want to know is how can this project be better than Tor? Does it solve the issues that Tor has found and fixed? Does it solve issues currently in Tor that have not been fixed but are known? Is it as secure?

Just wait. It takes time for them to receive and process your email.

But that was not Tor's fault. That was operator error. That was Ross Ulbricht failing to have good Operation Security, not Tor failing to do its job. I guarantee you that people will be arrested and sites seized on your network due to the stupidity of the operators, not because the network is broken. Tor is perfectly fine and works as intended.

English please for everyone else.

Can you answer the questions I asked above?

They might allow refunds, I'm not sure. But I think they also exchange the Bitcoin for fiat immediately, so they no longer hold the Bitcoin. They also allow the merchant to withdraw sooner than other companies do. Instead of waiting a few months, I think they only wait a few days before letting merchants withdraw their funds.

Also, there is a problem of how to refund people. Do they refund the Bitcoin paid or the exchanged currency equivalent amount of Bitcoin at the time of refund. E.g. if I want a refund for something I bought for 200 USD with 1 bitcoin do I get a refund of 1 Bitcoin when its price is 300 or do I get 200 USD worth of Bitcoin?

Have you tried their support yet? I'm pretty sure that it is something on their systems and not you.

Paypal can just go into their database of paypal transfers and reverse a transaction. They can just delete it. So can credit card companies. But with Bitcoin, once the transaction is confirmed, it can't be deleted and the only way to refund is to trust that the seller will send the Bitcoin back. With Paypal and credit cards, the money doesn't actually reach the seller until much later. The third party companies can do all of the refunds and chargebacks. With Bitcoin, the money goes right into the seller's wallet, so instead of relying on a large credit card company or Paypal whose job is to manage these things, you need to trust the seller who only wants to make money.

You can't reverse a Bitcoin transaction. Getting a refund relies on trusting the other guy to send the Bitcoin back to you. Most large business will do that, but some of the smaller ones probably won't.

Yes

Only if fiat is involved

If it is a centralized exchange where people deposit money into your bank account, then it is only legal if you get a license. In the US, you would be considered a money transmitter business and you need a permit.

Whatever you want. It is your site.

Disclaimer: I am not a lawyer and this is by no means guaranteed to be accurate. If you intend on involving fiat, please look up the regulations with dealing with large amounts of fiat in the countries you wish to operate.
