Could there be a way for someone to 'reserve' a name for a little while? So I can go into the bitcoin wallet on my computer and make it so anyone who sends to "Durdleman" for example will actually send to my address?

Edit: Actually, if there's a domain name service, is it possible for the bitcoin.org people to have a bitcoin name service as well?

This has been discussed before, but I don't know how widespread it actually is:

Third party services can easily do this. Like Backslash where you can send to a name.

...

blockchain.info (http://blockchain.info) allows "alias" names for their wallets.  Look for how to do it at "Account Settings" at the wallet home page, look for "alias".  Pick a word that no one else already has.  "gold", for example already has been taken (I checked), but "durdleman" probably has not, so you could use that.

Then each time you go to your wallet, type in "durdleman" in the "Identifier" field.

Easy-peasy!  :)

A lot of wallets will now let you send coins to email addresses and names in your wallet address book once you have it set up.
I never find the long address a problem because whoever i send to i just copy and paste the BTC addy, hard to make a typo mistake when doing it that way.

This, and the IRS would never know it's you.  ::)

Who has ever typed a Bitcoin Address?
We don't even type Account Numbers, most of the time.
So, who cares, how they look, how long they are.
Typing them is just another point of failure.

I had to do this once for a localbitcoins transaction. Buyer did not have a QR code for me to scan. I typed it in from reading it, then he read it off, then I read it off.

When it happened again with someone else I realized he could just copy and paste the address to me in a message.

Or, you could've created a QR-code on the fly: https://www.the-qrcode-generator.com/

Thanks. I'll have to keep that in mind if that ever comes up again.

I don't think that's what he's asking though. He wants to be able to make it easier for people to send him money by just having a handle of sorts. Personally I think it would make bitcoin a bit more user friendly if there was some way to send money to their 'name' or email address or something.

I just saw a thread over in the alt coin section about something similar. Seems someone proposed sending bitcoin via an alias. Edit seems it was necrobumped but it may be of interest to you.

GetGems app, your wallet is an alias to your username, you just type 0.1 btc and click send. Although this is exchanging with your contacts.

Since we anyway copy and paste addresses, it really doesn't matter.
Moreover, you can save frequently used addresses with a tag in your bitcoin client.

You can use vanity addresses as well, but some say it can compromise security somehow.

Is this the messaging app everyone has been talking about? You can send actual bitcoins with this? I thought it just used its own gems currency?

It totally comes down to whether people want to use a centralized name service for their Bitcoin addresses and transactions. Even if some casual user were willing, this could open up the floodgates to a whole new level of scams and thefts.

I wonder why you cant edit the names of the addresses you create in bitcoin qt, or why there isnt a section to put them in order nicely like "friends" business" "exchanges" whatever.

Well I guess BitcoinQT really is just the basic reference-implementation of Bitcoin. If it comes to usability, features, and things that make people want to use Bitcoin, they're better off with third-party wallets, especially lite-wallets. Having to download the whole freaking Blockchain is the biggest caveat of BitcoinQT!

No bitcoin transactions is possible it has its own wallet, gemz tokens are used for rewarding users for participating within the network through airdrop (to be released soon along with iOS) and payments for different advertisement purposes. Android has been released, i suggest reading the  community Q&A (https://bitcointalk.org/index.php?topic=758004.msg10187297#msg10187297).

Bitcoin addresses should only be used ONCE.

Bitcoin addresses are designed to be single use addresses for sending payments to your wallet. Though technically they can be reused as many times as you want, doing so significantly impacts your privacy and the security of your coins and it has a signifcant impact on the privacy of everyone you directly transact with and a small impact on the privacy of everyone using Bitcoin. Therefore you should never reuse an address and always use a fresh address for every transaction. You may notice many wallets (such as Bitcoin Core and the new beta version of electrum) are now "hiding" used addresses and now have a receive tab that gives you a new address each time you want to receive coins, this is to discourage address reuse.

Such a solution as you are describing will only encourage address reuse, which is bad for the above reasons. However there are things like genjix's stealth address implementation which essentially allows the sender to generate a new address in the receivers wallet, that when combined with a keyserver of some sort could implement this in a safe way, and I believe one day we will be using something like this and Bitcoin addresses will no longer be a thing the user even sees. The whole idea of a Bitcoin address is very flawed.

Yes only for the question of anonymity , but maybe some person doesn't want to use every time a new bitcoin address and prefer to keep/use only one (like a merchant).

this is good for non tech peeps to send btc

If you use Coinbase, you can send to email addresses instead of Bitcoin addresses, if the recipient is a fellow Coinbase user.

That said, what's so hard about copy and paste?   :D

Anyone in an office job, does it at least once a day.

new technologgy we can use camera to detect barcode of address
smartphone 2fa

Not exactly for anonymity, anonymity is a different issue altogether, it's for preventing someone from very easily figuring out who you are transacting with.

It would be a bad idea for a merchant especially to reuse an address, how would they know which payment is for which order? if you give each customer a unique address, then you can assume if a payment arrives to a specific address it should be attributed to that order, but if you are using the same address for every customer, then it becomes difficult to figure out who has paid and who hasn't.

The other problem is security. Once you send money from a Bitcoin address, you expose it's public key. If in theory a quantum computer capable of running Shor's algorithm was ever invented, it would then be possible to crack the private key. Of course such a quantum computer is science fiction, but if somehow someone happened to build one, they would only be able to spend coins from reused addresses. So in this sense reused addresses are less secure.

Bitcoin addresses aren't supposed to be reused, there are many downsides.

yes it would be simpler if the address can we remember, do not have to always copy and paste :)

But the problem is the same as with passwords: if average person uses password he can safely remember, he can assume the password is possible to bruteforce in reasonable time

Exactly WHAT is the problem with all the letters and numbers? You NEVER have to remember or manually type an address. You can always:

• copy/paste
• share (from mobile apps)
• scan a QR
• click a bitcoin payment link
• import/export complete wallets
• etc

Besides, typing addresses or names or IDs manually will typically result in typing mistakes. With the options above you can't go wrong. So it's faster, easier, and safer.

yes sometimes they also create the same username and password, almost all websites. let alone a website that is not clear

Addresses are not meant to be remembered. I think Satoshi expect us to copy and paste into emails and messages. Address shortening is nice, it can't be used if the address has no previous transactions.

not in the blockchain itself obviously but you could make some kind of program that does that.

If you would really want that though is another story, as it will be quite easy to trick people into sending it to the wrong address. Or something as simple as a typo could really screw you up.

What if I registered dudrleman, Durdlemen, Durdlemam, Durdelman, Durdeleman, Durdlleman, etc. (you get the point). and someone wants to send you money and they mistype and I get your money instead.

It would be quite profitable to create accounts for all common typos of big companies.

But sure, you can make something like a DNS, if we want it is an entirely different story.

On the other hand, you could link one of your addresses to some kind of app (like whatsapp, but obviously not whatsapp itself) and send small amounts through there. But for large amounts I personally would not risk it.

I believe they are making an app called sendcoin or something like it which is meant to be a whatsapp like thing with bitcoin integrated in it.

security no, privacy yes.

if someone knows one of your addresses, and if you ever pay with or get paid to that address everyone who knows that address belongs to you might figure out where you are spending your money.

But you can easily avoid that by using several addresses for several purposes, or just generating a new one every time.

It's not like there is a finite amount of addresses or anything (technically there is, but we can act like they are infinite).

Just use a vanity address for official purposes and disperse the coins you want to use through other addresses. Nobody will be able to see how you spend them (easily).

Why would a merchant prefer to keep/use one address? Remember: technically, he keeps all his addresses. Once an address has been used in the past, or sent to a customer for later payment or whatever, it can always be used later on, even if the merchant's wallet has generated new addresses in the mean time.

You don't 'discard' an address and switch to a new one, but rather you generate an additional, new address for every new payment (with the old ones remaining active as well). The balance of your wallet is not the balance of your last or newest (or any one particular) address, but all addresses combined.

well personally i have dozens of addresses, it's more easy to see where a payment is from that way.

makes it much easier to see if it was a donation (and from which website) or a payment of some sorts (and who paid me) etc.

i dont really worry about privacy that much (i mean yes i dont like people knowing everything about me but i dont worry about it to a pointof changing addresses every single time), but convenience is nice.

by the way most merchants use automated systems which do use a different address every time, so they know which payment is from which order.

The long address is maybe annoying but just copy paste it or use QR codes.

It would have been better if the addresses were 1577 characters long, and contained random gibberish characters. 

That way, we'd be sure that NOBODY would be as stupid to manually type an address, or even try to remember it.

Remember folks, ALWAYS use copy paste / share / QR / links!

I am sure that in few years we will see other form of addresses (shorter?). I personally had an issue, where I met a buyer (For physical goods) and he wanted to pay in BTC. He didn't have any QR code reader and I wasn't able to connect to the network (to mail him my BTC address) He had to copy it manually to send the funds (he used his BTCe account to do so). Was a bit annoying

Blutooth, NFC or even SMS?

Just be sure to copypaste the whole thing, i never had problems with blank spaces and so on.
