Re: ARG Puzzle with 3.5 BTC Private Key Prize

There's one last file that hasn't been used from the DOD game.

Code:
https://mega.co.nz/#!nUkAVbAQ!f9iGWcW8gNOwKkCIYIfuvk1e7qy_1w7zXOShJVLMTK8
The file from that link is sped up, but it looks like the sampling rate was left at 8000 Hz. Every other file in the sound folder that I checked has a rate of 22050 Hz.

Instead of speeding it up, you can change the sampling rate to 22050 Hz on the original and get something of similar length and sound to the file above, but not exactly the same.

I'll post this here for comparison if anyone's interested:

There's definitely some kind of file/data embedded in Space.mp4, with ffmpeg, I can do:

Code:
ffmpeg -i Space.mp4 -c:a copy -c:v copy out.mp4

and out.mp4 will be about 2.1mb smaller, even though it contains the same two streams.

Code:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Space.mp4':
  Metadata:
    major_brand     : mp42
    minor_version   : 0
    compatible_brands: isommp42
    creation_time   : 2014-02-25 11:26:52
  Duration: 00:02:48.21, start: 0.000000, bitrate: 444 kb/s
    Stream #0:0(und): Video: h264 (Constrained Baseline) (avc1 / 0x31637661), yuv420p, 640x360 [SAR 1281:1280 DAR 427:240], 244 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc (default)
    Metadata:
      handler_name    : VideoHandler
    Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 95 kb/s (default)
    Metadata:
      creation_time   : 2014-02-25 11:26:56
      handler_name    : IsoMedia File Produced by Google, 5-11-2011

In addition, I think I found the original copy of the video file (before extra data was embedded into it):

Code:
youtube-dl --format 18 https://www.youtube.com/watch?v=3rysbn9bZ54

This file contains the same video and audio streams found in Space.mp4. If extract using ffmpeg:
Code:
ffmpeg -i Space.mp4 -c:a copy -c:v copy a.mp4
ffmpeg -i Laffe\ the\ Fox\ -\ Left\ Alone\ in\ Outer\ Space-3rysbn9bZ54.mp4 -c:a copy -c:v copy b.mp4
sha256sum a.mp4 b.mp4

I get:

Code:
37f60f1717c142e15baec5a429a0ff07ed1d6efe122a06a15a77228170ed051f  a.mp4
37f60f1717c142e15baec5a429a0ff07ed1d6efe122a06a15a77228170ed051f  b.mp4

So I'm pretty sure that it's the original file before extra data was embedded.

So, now the interesting part, let's check the size in bytes of Space.mp4 and the original from YouTube:
Code:
du -b Space.mp4
9356135 Space.mp4
du -b Laffe\ the\ Fox\ -\ Left\ Alone\ in\ Outer\ Space-3rysbn9bZ54.mp4
7209006 Laffe the Fox - Left Alone in Outer Space-3rysbn9bZ54.mp4

9356135-7209006 = 2147129, which is the number found in Number.txt

So, there are 2147129 bytes of additional data besides the audio and video streams in Space.mp4


Edit: extract the extra data with this:
Code:
dd bs=1 skip=7209006 if=Space.mp4 of=binary
The sha256sum of the extra data is cbd47112ad2b9f3661e6506c7999afabd0f468b3a4acec81e0618ef98cb24bf3

 Is there an online wallet for this?
someone on Reddit is working on an online wallet:
http://www.reddit.com/r/dogecoin/comments/1swkf2/it_has_arrived_online_dogecoin_wallet_currently/

Online wallets should be discouraged though (in my opinion), especially since it seems many Dogecoin users are new to crypto-currencies.

If some of you are interested, I created a new pool: http://doge.cryptovalley.com

The pool is 10 minutes old so the hashrate is low but I offer 0% FEE FOR LIFE to the first 30 members, come on, be the early-adopter of the pool, by the night the others will follow and we will begin to find blocks and you, early adopters will pay no fee at all Wink


PS: the servers are located in New York City with very good latency and I promise you no downtime (I am registered on this forum since June 2011, so i'm not like these guys who know nothing 'bout cryptos and start a pool with 2h downtime per day)

Signed up as well, hope I'm still in the first 30. (username is Scylin, if you could check Smiley)

I have some seriously messed up ping though, prolly cause I'm not from 'merica

You're in the 30.
No, the server is overloaded. Little maintenance of 2 minutes at 0:10, just adding more CPU Power, 2 minutes, not more Smiley Don't stop mining, cgminer will stop and start automatically as the pool restart.

Says my account is locked now. ):
I have the same problem.

It's a pain for me to convert BTC to fiat and I don't want to get fiat stuck in an exchange I can't withdraw from.

Call me lazy, but it's easier to just buy things with BTC.

I was thinking of making some paper wallets for BBQCoins the other day, now I have some!

Just a heads up, when I went to print 3 wallets per page (the default), the site logo image still showed up on the top of the printout and so only two wallets made it on the first page and the third got bumped to page two (I tested on Chrome/Ubuntu and Firefox/Ubuntu-Gnome). I simply changed the source to remove the image at the top of the site and I was able to print three per page. bitaddress.org hides the site logo on print; all that needs to be changed is add 'id="logo"' to the tag for the bbqaddress.org logo since the CSS media types are already in the code.

That's .2% not 2%.

2% of 200 should be 4.

Hmm Ya, true. Which makes it only 7% a year.  
That seems about right, unfortunately, based on the stake I've generated the last few weeks. I was thinking it was a bit less than it should have been...

Re: please create NVIDIA-only Coin
by
Voyager
on 01/09/2013, 18:31:16 UTC
Question was just if it's possible there would be a coin in which nvidia can have the advantage. I'm sure there are lots of people in similar position that would be happy with this.
Hashcash based coins? no
Coins based on some other proof-of-work? maybe

It wouldn't be possible to create something that can only be mined on NVIDIA hardware, but there could be some computational problems where NVIDIA hardware might have an advantage in (at least initially).

So, to answer your question, it *might* be possible.

The problem is, I don't think anyone putting in enough work to design such a coin (based on a different proof-of-work) would care about something like this. It really doesn't do anything to secure/decentralize the network. True, it might work at first since there are not any mining farms based on NVIDIA, but there are plenty of render/compute farms based on high end NVIDIA hardware (Tesla), so it wouldn't be something that would be advantageous to laptop/single-GPU users in the long run. Personally, I think it's often forgotten that crypto-currencies are not designed for miners, and mining just provides an incentive to expend the electricity needed to decentralize the system.

Triton, a moon of Neptune, is the largest moon in the solar system to have a retrograde orbit, meaning it orbits opposite of its planet's rotation.

Why is the block 202kb?
We're kind of stuck on it, transactions are adding up quickly  Shocked

39 minute block.

78414 -- Mon Jul 22 15:46:00 EDT 2013
78415 -- Mon Jul 22 16:25:42 EDT 2013

Any idea what happened?
My CPU usage dropped below 100% during the block (each core was at about 30%), I was wondering if it stopped mining so I restarted. Maybe some miners stalled?

I just found a block on the testnet with the code optimizations posted a few pages back. This was on an Intel Atom getting about 46 PPS. For experimentation, I also changed the nMaxSieveSize to 250000 and still got a block. I'm not sure how this will influence things in the long run though. The lower sieve sizes do seem to increase PPS at the moment though.
Edit: found another on the testnet, I'm going to try this on the main network now.

People are probably block robbing on their optimized clients. Someone has got to release an optimized binary.

Yeah no friggin kidding. 40 hours at 79 PPS average and nothing. Seriously. I've asked 10 people so far to help me learn how to compile code to add my own personal flags... I'm not asking for answers, just the method to adjust some variables.

This is just as bad as instamining in my opinion. Pretty obvious by now that a 'select few' people are robbing this coin blind before most people can even find blocks. Same shit as as instamined crapcoins launched at 5 am pacific with botnets ready to go. Not sure if 100% intended by OP but releasing a coin that 'most people' take several days to even figure out how to mine is pretty damn weak.

Moving on.

I disagree.

What's wrong with someone optimizing the source code? They're taking a risk too.

Why should someone release an optimized binary? The source code is available, and tweaks have even been posted in this thread; it's just unknown right now if they'll make any difference. Several people are trying them on the testnet.

Also, it was not at all hard to mine. It took literally one command to start mining.

Hey guys, how many blocks have you mined now? I've mined 3 so far. 61 XPM.
2 blocks. Block #12 and block #290.
I'm working with an i7-3770 and Xeon L5520. The i7 got both blocks.
I also got one orphan somewhere in-between those two.

How many "primespersec" are you guys getting? I have an i7-2700k and it is fluctuating between 20 and 120 primespersec for me.
About 200 on an i7-3770

Still haven't gotten any coins though.

Thanks for the announcement. This should be interesting, I've been waiting for a coin that has a block reward based on difficulty. Hope the launch goes smoothly, it seems with the new coins, the launches are getting worse and worse, we could really use a smooth one Smiley

As I understand, the reward is proportional to the hash power? Or is it proportional to the current difficulty?

Can't you read between the lines? Its the same scumbags doing the same "litecoins scammed before GPU mining was possible so we are going to scam too but 100's of times more because we have not only GPUs now but also hundreds of times as much Ghashes than litecoin had".

-MarkM-


I understand that all future launches will follow the same disaster as long as starting difficulties are 0, it sucks that all the launches are nothing but latency races now. This one surely won't be different at launch, there will still be just as many orphans. What I am interested to see is how the low starting reward works out. There have been several coins (BitBar, Mincoin) that started with a high reward that dropped quickly, so most of the coins in existence were mined right away when latency was the tie breaker, by the time mining was working right, the reward was nearly nothing. If the reward started low, shouldn't the result be that there aren't many coins mined total until the difficulty gets up to a reasonable level?

It could all be avoided with a higher starting difficulty though, like you've said many times.
