One way might be to have the landlord generate a different address for each tenant. So you pay your landlord using address A, and your neighbour pays using address B, and the landlord can tell who the payment came from by the destination address.
That doesn't prove that the payment came from your wallet of course, but this allows somebody else to make the ...
First of all, it is likely a violation of PayPal's Acceptable Use Policy as of Oct 2011:
3(h) involve currency exchanges or check cashing businesses
Given this, it's unlikely that PayPal would be amenable to helping at best, and may close your account (and freeze the funds it had for six months) at worst.
Another chief problem is the high likelihood of ...
Here's a simple way to do it:
On bitaddress.org, use the "Paper Wallet" tab and create 1 address
Using your Bitcoin client, send an amount of bitcoins to the Bitcoin Address on the paper wallet
Print the paper wallet and give it to your friend
Tell your friend to create a wallet at My Wallet. He can then use the "import from paper wallet" feature and simply ...
You can't get money on the Ripple network unless you trust someone to owe it to you. To have $100 in the Ripple network, someone must owe you that $100. If you haven't chosen to trust anyone to owe you money, nobody can owe you $100 and thus you can't have any money.
So when you give money to a gateway, you must allow them to pay you in IOUs. And if someone ...
The only three ICANN accredited registrars who accept bitcoin presently are No-IP, easyDNS and Namecheap.
It's a short list.
Liberty Reserve (though they did freeze some customer funds recently until they became verified)
Bank Wire (though see comment below)
Here's the payment methods hardness list:
The correct way to do this (beware: extremely technical) is to:
Reserve a coin of your own for each auction (the "auction coin"). This shouldn't be too big (you will lose it until the auction is over), but try not to make a dedicated one just for the sake of the auction (use a small one you already have!).
Create an address for the auction's winning bid (...
http://www.cryptocoinsnews.com/news/the-mathematically-secure-way-to-accept-zero-confirmation-transactions/2014/02/13, here is what services like MyCelium and BitPay may be doing:
More specifically, with every additional second a larger percentage of active Bitcoin nodes will have heard the original transaction and everyone viewing the blockchain can ...
It would be possible if you can generate multiple receiving address for each transaction. That can be done using your public and private keys.
Give each user a separate address of yours. Then you should be able to track.
Etsy merchants that accept bitcoin have been tagging their shop items with 'bitcoin' so that a simple search shows what is available:
An email to email@example.com got this response about being allowed to use bitcoin:
"If you would like and are able to support a third party payment system, you are welcome to use another ...
You can give them the private keys associated with given Bitcoin Address, but it's generally not the best way of transferring Bitcoins over. You ought to just make a regular Bitcoin transfer. Both of you would need to be using those for handling Bitcoins anyway, so this way would be identical to what you will be doing anyway.
You can for example check the Block Explorer's info about a given transaction. For example, given transaction 1c480aad976c61b51ae47401a554b09f65efe6f95f644041f838d9129e09167c, you can see that the only input was associated with address 1HnjAo2nbHGFDto86smcFiF3uUwfvNJ4cS.
However, generally you should avoid using transaction inputs for basically any purpose -...
And Blockchain.info has added Facebook "pay a friend" feature.
Another method -- for requesting funds is:
Another thread on this topic:
This is not recommended.
If the customer uses a fully controlled wallet he will get the coins, but will be confused about their source because the address would carry the label of some other provider.
If the customer is using a shared eWallet, he might not get the coins at all because the address isn't his.
There is no way one can have his account blocked in Bitcoin and there are no funding or withdrawal amounts limits. However, you should take into account that all Bitcoin is pseudo-anonymous, i.e. although there is no direct connection between you and your account address, all transactions are public and could be tracked by anyone.
There are billions of people that don't have access to credit cards and banking facilities that the privileged people take for granted. There are also people that get into financial trouble and lose all credibility in the banking system. Bitcoin provides a way for these people to transact without being part of the banking system. Coffee, however is a very ...
In lightning the receiver of the money comes up with a random secret and comits to it via the payment hash. Once all the hashed time lock contracts (htlcs) are set up along a path through the network from the sender to the receiver the recipient will release the secret preimage for the chain of htlcs to settle. The preimage can be seen as a proof of payment. ...
You can now use the Bitcoin payment protocol to do this.
Here is an easy to use implementation from Bitpay.
There are already a few wallets that support this (including the reference client). More will be released soon.
Create an Instawallet, send the funds you wish to pass to the bitcoin address for that Instawallet, and then just give the Instawallet URL to the other person.
The transfer payment from your wallet will need to confirm before the Instawallet balance will reflect the payment but once it does, those funds are available to anyone who knows that Instawallet URL....
As PayPal is not a bank and reserves the right to freeze your account for whatever reason they deem fits them, you should never use PayPal, unless you can afford to lose your money, or are prepared to take them to court and win, should they steal your funds.
While this is not specific to BitCoin per so, it is probably likelier to happen with edge cases that ...
If you run an Escrow service, yes, you could get paid to process transactions. But that's probably not what you're asking about.
In normal cases, transaction fees go into the reward for a new block being mined and are earned by the miners that create the new block. This takes specialised hardware and software. If you want to get your feet wet in this area, ...
There are a number of approaches, and the best method for you will vary on a number of factors.
For instance, if you sell a digital good it might be easier to simply sell the item through an online store like CoinDL, where you simply direct your customers there.
Similarly, if you sell a couple of items at a fixed rate, you could sell it on BitMit.net, ...
I contacted BitPay support about the issue and they said that it'll just work.
So we made our payment via 3 different transactions. As soon as all transactions were made, the BitPay window informed us:"This invoice has been paid." At that moment either one of the transactions had a single confirmation or none had any. Then came the confirmations.
Creating a new address for every transaction (not just every single client) will allow you to maximize your payment tracking capabilities.
In case you have a single address for all of your payments it's really hard to track who sent you what. This will start changing from 0.9 on, but for now we have to stick to what is already implemented.
Having one ...
If he just wants to receive money to cover your rent, suggest him a different address per tenant as in Greg's answer, it's simplest and cleanest (and you could even have a benefactor paying for you).
Should he want money from you specifically... If I recall it, you can add small texts in your transactions - but that's an advanced feature that requires, as ...
With Bitcoin there are various ways to mitigate the risks and issues you mention to allow some use of payments with zero confirmations instead of waiting for sufficient confirmations to be sure the payment is irreversible.
With Ripple, once a transaction is validated it is irreversible. Ripple transactions usually validate within seconds (5-20 seconds ...
After one confirmation, the transaction is very unlikely to be double spent. However, each further confirmation reduces the probability exponentially. Basically, the number of confirmations provides additional security that the transaction will not be reversed.
One reason a retail store or individual might wait for more confirmations to ship is time; it ...
To transact in Bitcoin you will need to broadcast the transaction to the Bitcoin network. At this time an internet connection on your phone is going to be a requirement, a wifi hotspot at the cafe is all you need.
In theory there are other ways to get the transaction to the network for example sending the transaction directly from your phone to the point ...
The QR code is simply a convenient way of sharing an address, to avoid having to type it. It encodes exactly the same information as the alphanumeric address and provides no additional security. If you have another way of giving someone an address (e.g. sending it to them by email), there is no need to use a QR code at all.
How the other person verifies ...
