You can also do it with a single transaction, but that's less impressive.

Note that this setup performs a single large transaction to all the addresses. This minimizes fees required.

Another item - you can test this feature by creating a CSV and loading it, but it does not try to send unless you confirm it - it chains into the raw transaction window that offers a sign or cancel option. If you don't enter a password (and have one set) then no TX can be made.

Hm, thats strange. I now copied your example:

Code:

"16Ad3kT79J4bUtpKACKTBbwDwJgykwGf5h", 1
"1MME7H55rfY1i9kNxv9K9cj8yqnShqzo2L", 0.0001

then copied it into the window appearing after "load raw transaction"-> from text and clicked on load transaction. The result is: "Electrum was unable to parse your transaction".

So something seems wrong with that function in 1.8.1 at the moment.

I was reading this article by someone connected to the multi bit project. He talks about how the exposure of addresses in a wallet is minimized by using bloom filters with "noise" when querying full nodes for transaction data. Is that something that electrum does when connecting to electrum servers?

Because we're talking to random computers on the internet and not a trusted third party, the filter is designed to let you control your privacy. It is not a list of your addresses, as it is with the blockchain.info wallet. It's actually what we call a Bloom filter (named after Burton Howard Bloom who invented them in 1970). You can't directly get the users addresses back out of a Bloom filter, instead you have to test each one you find in the chain against it to see if it matches. Also, the filter can be made "noisy", which means it randomly matches some other addresses as well.

The CSV code isn't in any release.  To use the CSV handling code, you have to create a CSV file and use my fork's new button to import the CSV.

Since i use the portable windows version i have to wait for the next version then. But i wonder why raw transaction from text is already included in the menu. Thats new i believe. But implemented without your code behind? Maybe its only for single transactions.

[Tachikoma]

Raw transactions are not the same thing as CSV transactions.

[SebastianJu]

Then i missed that. I only didnt saw that option before and since harningt spoke about that he built such code i thought thats the thing.
Then ill wait... till now i only had one testcase. But in case of a large refund it really would be best to let a calc-sheet create a csv and do everything in one transaction instead having to do many single ones.

[SebastianJu]

Since i have to do a lot of refund transactions in the next time it would be good if i would be able to do multiple transactions in one transaction. Is the development so far till now? Would be good when i could use it because i then only need to change my calc sheet a bit and create a big transaction.

What happened with http://electrum-desktop.com? Site says "This domain may be for sale".

sorry I have not worked on that at all; this will not be included in 1.9 unless someone else does it.
I think the way it should work is you open a csv file and it auto-fills a transaction dialog with all the outputs

Thanks

@ThomasV or Electrum: would be nice to change the URL in the first post.

Yes, either loading a csv-file or pasting csv-code. The same like raw transaction works. Only with more transactions that are merged into one single transaction. It would good if its possible to set a label for the transaction too.

I now did around 200 transactions by hand, took me 5 1/2 hour...  and i hope i did no error with all the copying. CSV-Transactions look risky on the first sight but when automatically create the transaction by ooo calc, doing a small testtransaction with the same workflow and checking the details plus doing in batches of 10 i think it would be safer in fact. Doing single transactions make you tired and the risk of copy errors or similar things is rising.

By the way... by doing the single transactions i often got this error. Probably when too many transactions were in queue or so:

Code:

error: {u'message': u'TX rejected', u'code': -22}

[harningt]

Guess I should post the pull request for the CSV import ... after I make sure it merges with trunk and 1.9 cleanly.

[harningt]

The pull request for master and 1.9 are:
https://github.com/spesmilo/electrum/pull/282
https://github.com/spesmilo/electrum/pull/283

I enhanced it recently to mirror the Import raw transaction details by having a forked menu w/ file and text inputs.

[SebastianJu]

If i could request a change to gui... the repainting of the lists... cant the list be again at the previous height? I mean when i have a couple of preferred addresses i always have to scroll down, then i can only chose one address at a time and when i changed it im on top again. I think it would be easier to handle if it jumps to the previous position. Thanks!

i think the proxy support is broken? Anyone can confirm that?

yes, it has been reported that proxy does not work

why are all electrum servers I try "Server is lagging (47 blocks)"?

A bug was discovered in the Electrum server code a couple of hours ago. Most server operators are fixing this as we speak.
