One way to view a Schnorr aggregate public key is as a non-empty set of public keys.

The interface exposed by this set of public keys includes at least the insert operation. This operation takes as input an existing aggregate public key (PK_a), another public key (PK_b), and returns an aggregate public key that contains both PK_a and PK_b.
Note that if both PK_a and PK_b are aggregate public keys, then this operation acts more like a union operation than insert.

One remarkable property of this set type is that its size, as a function of how many elements it contains, is constant.

Viewing an aggregate public key as a set of public keys raises the question of whether it exposes more set-like operations than just insert. For example, does it support the member operation, which takes as input an aggregate public key PK_agg, another public key PK_single and returns true if PK_single is contained within PK_agg and false otherwise.
Perhaps this operation can be implemented only by requiring more input data, such as a signature (created by the corresponding private key of PK_single) over a challenge created for the purpose of proving membership?

Another useful operation would be delete, which takes as input an aggregate public key PK_agg, another public key PK_single and returns an aggregate public key that contains all the keys of PK_agg except PK_single.

I am not aware of any other example of constant-sized set, which is why I'm intrigued by this possibility. I realize these operation may require multiple rounds (similar to producing an aggregate signature), but regardless I still think the possibility of a set-like interface for aggregate public keys holds great potential, which is why I want to start this discussion.

[EDIT:]

I'm running Armory 0.95.1 on OSX El Capitan.

When I open the Offline Transactions dialog, enter address, amount, fee and click Continue ("Create Unsigned" is checked), Armory freezes for about 20 seconds, and when it becomes responsive again, nothing has happened (the dialog is still open, and the same happens if I click Continue again).

At the same time, the following appears in the log:

Code:

RuntimeError: can't connect socket

I'm not sure what the issue is here. I'm trying to create an unsigned transaction, so I don't see why it would need to connect to something. It's connected to Bitcoin Core, according to the green text in the lower right corner.

Account-Based Blockchains Would Save Space & Ease Clearing

Ideas?

I've experienced this a couple of times.

I open Armory, and it needs to scan the new transactions in the blockchain that it hasn't seen yet. This takes around 5 minutes. When it is done doing this, it's ready for use. If I then suspend my PC, turn it on again and open Armory, it now needs to scan the entire blockchain, which takes a couple of hours.

I don't know why this happens.

Here's the relevant log (I turned my PC on at 10:32, and opened Armory at 10:52 (it seems it had been running in the background)):

Perhaps the issue is that I open Armory while it's already running in the background? But it had disappeared both from the the top bar on the screen in Ubuntu, and the launcher on the left as well.

Let me know if additional info is needed to solve this issue.

Hi all

First of all, thanks for making Armory! I've been using it as my main wallet for over a year now and I'm very happy with it. An offline wallet with a paper backup makes me sleep so much better .

I've changed the configuration of my system to run bitcoind as a service. This means that the bitcoind service starts as soon as my OS boots, and as a consequence it's always up-to-date when I want to use it.

It's running as its own user "bitcoinuser" and it stores the data files in /home/bitcoinuser/.bitcoin/, which means Armory needs to look in that directory.

Currently this is only possible by specifying it as a command line option, which means I need to edit the Armory .desktop files in /usr/share/applications every time I update Armory (since these are overwritten).

It'd be much easier if I could just specify this directory in the Armory settings, so that they're saved along all my other settings in ~/.armory/ and I won't need to update any files after updating Armory.

I want to create a bot that posts the dividend of the ASICMiner stock when it arrives at my address.

For that I need to be able to post to bitcointalk.org using an API. Does such a thing exist, and if so, how do I use it?

So I'm just testing the blockchain.info receive API (http://blockchain.info/api/api_receive) and I've created a receive address by sending the following request (using the test form on the site):

Code:

/api/receive?method=create&format=plain&address=19kiXZ7v5fr7p7SJyZSENqNudyMPpXJnV9&shared=true&callback=http%3A%2F%2Fruneks.dk%3A8154%2F%3Fusername%3Djimmy

The response was

Code:

{"input_address":"177uzgnG5uh4ZZjNyN1XTvAMajRmmoWjpq","callback_url":"http://runeks.dk:8154/?username=jimmy","fee_percent":0.5,"destination":"19kiXZ7v5fr7p7SJyZSENqNudyMPpXJnV9"}

I've sent two payments to 177uzgnG5uh4ZZjNyN1XTvAMajRmmoWjpq. I haven't received a callback for either of them, and the balance of that address has not been forwarded to 19kiXZ7v5fr7p7SJyZSENqNudyMPpXJnV9.

In an earlier test it worked (as you can see from the balance of 19kiXZ7v5fr7p7SJyZSENqNudyMPpXJnV9).

The "Fire Test Callback" test works fine. I can see that I receive a callback after pressing this button, but I have received no callbacks from the actual payments (nor have they been forwarded to my address).

Is it because I've used the same address twice?

I first tried to forward payments to the 19kiXZ7v5fr7p7SJyZSENqNudyMPpXJnV9 address and got the address 15WBVNkxhxKLgd1eewFAgH1BipuGpZeK3w back. I successfully sent funds to this address and they went to my 19kiXZ7v5fr7p7SJyZSENqNudyMPpXJnV9 address. But the above request, which should forward to the same address, doesn't work.

Let's discuss this paper: http://spar.isi.jhu.edu/~mgreen/ZerocoinOakland.pdf

What are your thoughts on this? I don't understand a lot of the technical stuff in the paper, so I'm interested in hearing your opinions.

Abstract—Bitcoin is the first e-cash system to see widespread
adoption. While Bitcoin offers the potential for new types of
financial interaction, it has significant limitations regarding
privacy. Specifically, because the Bitcoin transaction log is
completely public, users’ privacy is protected only through the
use of pseudonyms. In this paper we propose Zerocoin, a
cryptographic extension to Bitcoin that augments the protocol
to allow for fully anonymous currency transactions. Our system
uses standard cryptographic assumptions and does not introduce
new trusted parties or otherwise change the security model of
Bitcoin. We detail Zerocoin’s cryptographic construction, its
integration into Bitcoin, and examine its performance both in
terms of computation and impact on the Bitcoin protocol.

So here they are. Legit? I presume so, but I have no friggin idea.

Hey all

I'd like some *guitar* tabs for this song http://www.youtube.com/watch?v=WwG9of7EUi0
Must be 100% accurate. If you think 0.5 BTC is too little, make me an offer!

I've been wondering if it would be helpful to include a "Cryptography" child forum to the "Development & Technical Discussion" forum. I'm in the process of learning some elliptic curve cryptography, and I have some questions that are fairly cryptography theory-oriented, and I feel they would fit better in a subforum dedicated to cryptography, than to this forum which mainly concerns the client, and the protocol and software surrounding it.

Hello all

I'm planning on opening an account with an online trading firm called Zecco. I'm located in Europe though, and they charge $50 for an international wire transfer (yikes!). ACH transfers are free though. Is there a way for me to pay some company or person in bitcoins, who then send send the amount, converted to dollars, to an account specified by me using ACH? I don't really know how ACH works, if it's just an account number I need to be able to send funds, but I've read that transfers are reversible for up to 60 days, so I guess the party I buy the service from will have to be trustworthy.

Any reason why this can't be done? $50 is really a ridiculous fee, and might make my trading unprofitable considering I need to get the money back again, which is $100 in total, and then the intermediate banks will probably also take a cut.

Hello all

What I'm trying to do is basically create the data structure that would qualify as a valid bitcoin block, if its nonce caused its hash to be below the current target, where the address that would receive the generation output is specified by me.

What I've figured out so far is that I need to use bitcoind's getmemorypool request. From this I can construct all the necessary fields, as far as I can gather:

• prev_block is included directly in the output, that one's easy
• For merkle_root I first have to calculate the hash of each transaction included in the output, ie. first transaction in the current output is "0100000001da8d10a3b749dbda1658298d84512836c1bfb2bcbe7b61dcdd3e508bcb7e147700000 0006c493046022100e041a6e5df8c8b44231b4fee02b34e2f12d553ab54dc434c1bf95dffb68e5f 8d022100c74e5318b4c209397be7e1ea4f4ef783d036f5fbe894918e8e31c72e49f75fc30121034 ecf9a2859c419500001e05710bec6673db9a8ea5faaf07497c9c996e1d28f81ffffffff0280324c 35800000001976a914fc8e972d3f4c41b44a3ee71051aaf52f107ceb0f88ac005cb2ec220000001 976a914847641ad2efb44d949070bf6e7b1c367c70f194388ac00000000", so that transaction's hash would be SHA256(SHA256(<output>)) (after converting to and from little endian where necessary), and then the merkle_root would be a double SHA256 of a concatenation of all those hashes. Is this correct?
• timestamp is included in the getmemorypool as "time", and "bits" is there as well

At least one additional question comes to mind: is there a generation transaction included as the first transaction in the list of transactions output by getmemorypool and, if so, which address is the payout sent to?

Thanks!

I can't make use of the coupon code without paying (the equivalent of) a $25 import fee plus VAT, so I'm selling the code instead.

Suggested price is 1 BTC.

I want to pay 5 BTC for anyone who can transcribe the following song: http://www.youtube.com/watch?v=mWJtQUfL_Dc

You can see a lot of the chords pretty clearly from the video, and I've got the first few myself. But I can only 'see' the chords, I can't really listen to a chord and be able to play it. I've only been playing guitar for a little over a year.

We'd probably need to do some escrow of some sort, because I would need to verify that it really does match the track (according to my hearing). I need a perfect transcription. Perhaps we can split the 5 BTC into 5/<number of chords in the song> payments, and I pay for each successive chord so that I can verify along the way that it's correct, and so you don't have to show the whole transcription to me before I pay. I can cover the fees for that.

The following auction on bitmit.net looks a lot like a scam:

Hey all

I'm thinking of buying a used 5970 that has been used with water cooling. The thing is that the seller bought the item with the water block on. He has the original heatsink, but he has no screws for it, so I'm trying to find out which screws to buy in order to be able to attach the original heatsink to the card.

I know from this Ek manual that there are 21 screws in total, and where they are located, but I don't know which screws to buy. So I'm looking for some details on thread measurement, width and length of the screws needed.

As far as I can see, from pictures like this one and this one, the only really necessary screws are the 7 screws used to attach the heatsink, PCB and back plate together, and the 8 screws used to attach the heatsink to the PCB with the X-bracket on the back. The 7 screws that attach the heatsink, PCB and back plate are seemingly all of the same size, and larger than the 8 smaller screws used to attach the heatsink to the PCB with the X-brackets. But that's about what I know.

Can anyone help me out here?

Hey all

I would like to use AMDOverdriveCtrl to set the core clock and voltage of the two GPUs in my my mining rig - a 5870 and a 5770.
I have successfully made a script that sets these properties, and added it to be run in /etc/rc.local. The script looks like this:

Code:

#!/bin/bash
sleep 30
cd /home/user/
AMDOverdriveCtrl -b -i 3 .AMDOverdriveCtrl/5770.ovdr >> logs/overdrive.log 2>&1
AMDOverdriveCtrl -b -i 0 .AMDOverdriveCtrl/5870.ovdr >> logs/overdrive.log 2>&1

The problem is that when I start up my mining rig, and run "aticonfig --odgc" to see the clocks of my cards, they're at their default clocks (and voltages). So the script hasn't had any effect. This is printed to the log file:

Code:

Error: Unable to initialize gtk, is DISPLAY set properly?
Error: Unable to initialize gtk, is DISPLAY set properly?

The script works fine if I log in via SSH and execute it manually. But when run from /etc/rc.local, it prints the error message above.

[5870]

Hello all

I just recently found out how dramatic an increase in efficiency undervolting can achieve. In my mining rig I'd like to optimize this, and preferably get it to consume around 250W in total. Right now it's consuming around 265W. I'm running with the following voltage/clock settings currently:

5870: 750 MHz / 1.000V / 97W / 343 MH/s / 3.54 MH/J
5770: 750 MHz / 1.010V / 63W / 168 MH/s / 2.67 MH/J

As you can the 5870 is significantly more efficient than the 5770. Then again it's also running at 1V vs. the 5770's 1.01V. But I simply can't get the 5770 to run properly at 1V at 750 MHz. At this voltage it keeps stalling in cgminer ("declared SICK") unless I run it at 700 MHz.

What are people's experiences with 5870's and 5770's and stable voltage/clock combinations of these?

By the way, the 5870 is an HD-587X-ZNFV V1.3 5870, and the 5770 is this Sapphire card, though I'm not sure if it has 512 or 1024MB RAM.

On satoshi's profile on this board, it says that he has made 575 posts. Yet when I search for posts made by him (either through the "Show the last posts of this person."-link or by using this board's search feature, I can only find 540 posts.

The first post, seemingly, is the "Welcome to the new Bitcoin forum!"-post. It seems strange if he has made 35 (575-540) posts before that one, so unless his most recent post is newer than this one regarding DoS attacks (which his "Show the last posts of this person."-page displays as the newest), I can't figure out where his other posts has gone.

Can anyone help with this?

Also, as his first post says, there was an old forum, previous to this one, that was once available at the address specified in the post. This URL gives a 404 now. Does anyone have a backup of the threads from this old board?
