To request bitcoin from someone else you need to provide them with a “Bitcoin address”. They look like this 1AhN6rPdrMuKBGFDKR1k9A8SCLYaNgXhty and you might want think of them spil a unique address for a payment.
Anyone that you give this address to will be able to send you bitcoin from that ogenblik on. Reminisce that they may keep this address for a long time so you should never abandon a wallet by throwing away the wallet words.
It’s very unlikely you’ll everzwijn have to type a Bitcoin address by palm so don’t worry about having to memorise them.
Bitcoin addresses are intended to be used just once since for technical reasons (see zometeen) they become a little less secure after you have spent the bitcoin received by them. For this reason MultiBit HD always gives you a fresh address each time you click the “Request” button.
- Click Send/Request on the sidebar, then click the Request button.
- Inject an amount denominated ter whatever bitcoin unit you have chosen te the left entry field or the amount te your chosen national currency ter the right entry field. MultiBit HD will perform a currency conversion using your choice of exchange.
- Click the “Copy” icon next to the Recipient opbergruimte to copy the address to your clipboard for effortless pasting into an email, instant message etc
- You may want to add some private notes to the this payment request. Thesis are held encrypted within your wallet and are not exposed to anyone else including the payer.
- Click “Finish” to go back to the Send/Request screen
Displaying a quick response (QR) code
QR codes are a convenient way to transfer information from one machine to another. MultiBit HD will generate one for you by clicking the QR code icon near the Recipient opbergruimte. This makes it effortless for you to request payment from smartphones with Bitcoin wallets installed.
Tracking your payment request’s progress
Once you have requested a payment it shows up ter the Payments screen with the status ‘You requested’. At this point you are waiting to get paid, the general process is spil goes after:
The other person sends you bitcoin and the status moves to “Unconfirmed” to indicate that the Bitcoin network is processing it. You will also get a green bedachtzaam brochure with a message indicating that bitcoin is incoming.
You will see at the top of MultiBit HD the message “+ Unconfirmed: mBTC xyz”, where “xyz” is the amount of bitcoin they sent you. You cannot spend unconfirmed transactions ter MultiBit HD since they could fail to confirm for many reasons.
When your request has bot paid and before it is confirmed the status of the transaction moves to “Receiving”. If the other person only sends you part of the bitcoin you requested, the status is “Part paid” until they send you all that you requested.
Bitcoin miners process all the unconfirmed transactions and waterput them into blocks. Once this happens your transaction is confirmed and you can spend it. This normally takes inbetween Ten minutes and an hour. Once your transaction is confirmed ter a block its status switches to “Received”.
How can I find out more about a transaction ?

Why should Bitcoin addresses only be used once ?
This requires a technical explanation of how Bitcoin addresses are created. Te brief, a Bitcoin address is a hash of a hash of an elliptic curve public key ( RIPEMD160(SHA256(pubkey)) and some other integrity checking information. This process makes the address brief so it doesn’t take up much space te the block chain, and also makes it very hard to work back from the address through two different hashing algorithms to arrive at the original public key.
During the Bitcoin spending process the public key is exposed te the block chain for all to see. This is necessary to permit everyone to verify that the address matches the public key and that the private key wasgoed used to sign the transaction, but liquidates the hash of a hash protection. This weakens the security from that of an address to simply the mathematical relationship inbetween a public and private key within elliptic curve cryptography. While this is immensely strong, it is still weaker than the extra hash of a hash which is why addresses should not be re-used.
