You can generate an account number offline and send nxt to it.
I must have misread something as I thought you couldn't do this (as you had to "register" an address) - can someone else confirm that this is the case?

Well if you download the client to a computer and disconnect it from the Internet you can create an account. With that account number you can then send NXT to it once you are back online. Passphrase would never be used on the Internet. In theory this should work, I have not tried it myself. Edit: Just tried it, you can unlock accounts fine offline.

Hey EpicThomas, doing good by returning real NXT to real people would be WAY more cool than anything done by ANY imaginary superhero. Just sayin. ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fscontent-b-atl.xx.fbcdn.net%2Fhphotos-prn2%2Fq71%2F1511262_605995709455124_2038474529_n.jpg&t=665&c=ZuuQ8ASwlDeTYw)

If you send NXT to an address and don't open the address after edit:spend any funds, no private/public key pair is generated for that address. This means the account is only protected by (if I'm remembering correctly what CfB said) the 64 bits of the account number, not fully protected by all 256 bits of the private key.

Yes - this is what I had recalled - so what I was hoping one could do is to generate the address and somehow publish the public key without the private key (or pass phrase) ever being even temporarily on an online computer.

Can the transaction fee be dropped for more affordable messaging? I know this has already been discussed but 0.076$ for a single message is worse than SMS.

Not yet.
But Darla Sue and Bonnie may be talking to him tomorrow night and over the weekend about that.

I think I recall him saying that was a yet-to-be-implemented feature. You are right about not ever being official on the blockchain until sending at least 1 NXT to another account, or generating an alias or something else that causes the amount of NXT in the account to go down. Until that transfer happens the address space for the account is only 2^64 and not 2^256. At least for now anyways. But personally I dont think it should ever change, otherwise people will start spamming empty accounts into the blockchain. That being said, if you really want to protect yourself, I have outlined some steps here: http://forums.nxtcrypto.org/viewtopic.php?f=17&t=267 Note that this procedure elects to be online to lock in the account, but via a linux live CD. If you want to go the 2^64 route then keep the linux disconnected and then you also dont have to do the full procedure, but note that to be 100% sure here its probably best to not just disco your PC from the internet and do it, especially if you're running windows.

Thanks - although if I am understanding this correctly then your public key has been made public when creating the alias or sending 1 NXT. So if the EC is cracked down the track then your NXT would not be safe - so does this mean that by design you cannot store NXT offline safely (meaning safe from some QC that has cracked EC) without better than 2^64 of entropy?

Interesting! I had missed that part. Now I have to tell the person whom I had given a NXT gift card for xmas to make sure they do a transaction on that account. Checking that account with: http://localhost:7874/nxt?requestType=getAccountPublicKey&account=[GIFT_CARD_ACCOUNT_NUMBER] verifies that there is no public key for that account. Neat! Thanks for clearing up one of my misconceptions!
