[Bitcoin-development] Suggestion: allow receivers to pay optional fee for transactions without fees

2014-01-16 Thread Dâniel Fraga
Someone sent me a very small donation (0.00121 BTC) without
paying fees. I don't know who sent it and I know this type of
transaction are usually rejected by miners. Take a look at it below:

Even with the a low probability of confirmation, I
was hoping that after a few days it could be included in a block, but
Blockchain.info simply removed it (I know the sender sent from a
Blockchain.info wallet, because he added a note):

https://blockchain.info/pt/tx/3cde47ee3979a46b36bd61bdb0caf9c11dea58ac99f17fb17b95728766de70e0

As you can see now it shows as Transaction not found.

My suggestion is: it would be nice if the receiver could have a
chance to pay the fee when the sender didn't pay any fee. For example,
I could pay a fee of 0.0001 BTC and receive 0.00121 BTC. In the end I'd
have 0.00111 BTC. Better than nothing.

Would it be technically possible to do that or it would be too
much trouble to change the protocol to allow the receiver to pay an
optional fee?

Ps: I'm not a programmer, but if the receiver could
optionally attach some fee to the transaction, even if he/she didn't
sent the transaction, this could be solved. Bitcoin-qt could even warn
the receiver he received a transaction without fee and if he wants 
faster confirmation he could pay a fee.

Ps2: if this is a silly suggestion, just ignore it. I tried on
Bitcointalk, but nobody answered.

 You can create a transaction which spends the output to yourself, attaching
 a fee to that transaction. In order for miners to grab the transaction fee
 on that transaction, they would have to also mine the original transaction.
 Likely, you'd have to do this by hand, but software could be written to
 simplify doing it. No protocol changes needed.

[Bitcoin-development] Suggestion: easy way to restore wallet.dat backup

2013-12-03 Thread Dâniel Fraga
I posted this on bitcoin-user, but nobody replied, so I'm
trying here.

Today, when a user uses bitcoin-qt client, it can make a backup
of wallet.dat easily through menu, but when he/she needs to restore
this backup, he/she must copy the file to the correct folder and
execute bitcoin-qt -rescan.

My suggestion: bitcoin-qt developers could implement an easier
way to restore. For example: a option in the File menu Restore Wallet
or Recover Wallet where it would show a dialog asking for the backup
file and everything would be done automatically (no need to do it
manually).

If we want everybody to use bitcoin, these operations should
be as easy as possible.

What do you think?
