To avoid address reuse, you would have to have a wallet on the server that the website calls using RPCs to get a new address from the wallet.

Or, just pre-generate a large number of addresses, and add them to a database. Then have your website display a new address from the database each time a user clicks a "donate" button/link.

Or, use HD wallet and have your website calculate the next address in the hierarchy each time a user clicks a "donate" button/link.

BTW: Is a VPN giving privacy to bitcoin-client too?!?

Privacy in what way? VPNs won't have any effect on the privacy of your transactions and addresses. They only hide your IP address, and it is nearly impossible to tell what addresses and transactions are associated with an IP address.

To avoid address reuse, you would have to have a wallet on the server that the website calls using RPCs to get a new address from the wallet. However, usually people don't do this for donations and just post the address because it is easier to do that.

Wow! Thanks for your fast and helpful answers!

Ok, if it's not recommend to reuse one adress - how should we deal with that as a project who just needs bitcoins for getting donations?

The people have to find one adress just to be able to spend something!

As i saw now in blockexplorer.com there was NO donations over all this 3 years?!

by the way- here our project: http://mayastudio.tumblr.com/64bit

thank's for answering!

Hello!

I have 2 questions as a beginner!

For our project we made a donation-bitcoin-adress and put it on our website!
We gave the Adress a label.

1. What is if we change the label once (in bitcoin-core and website)!

Is the Adress working right and can we get and see all transactions of the past and future (with old/new label)
or is this a wrong way which makes errors?

Maybe the labelchange is possible and don't break the adress?

The label is not something that goes out to the rest of the network or to the blockchain. Labels are local to your wallet only, so whatever adding a label, changing it, or removing it won't make a difference. Because labels are for your wallet only, you can set it to whatever you want and no one will know or care.

2. I know that is recommend for privacy to choose for every single transaction a new adress.

But it is technical possible to use just one adress for all donations over many years?

Yes, addresses can be reused and there is nothing to stop that from happening. However, it is recommended that you don't reuse addresses.

A label is just that, a label. It will, in no way, impact your address or transaction. You can change it to whatever you want, and how many times you want to.
