1  Economy / Games and rounds / #bitcoinchallenge 20000 bits for your videos of noobs using bitcoin on: March 07, 2015, 04:49:29 PM
X-Post from Beginners & Help ( mods feel free to delete the other one.


  I'm developing a new platform ( and concept that revolves around challengefunding. What is challengefunding? Challengefunding turns crowdfunding on its head. Traditional crowdfunding projects have a project owner who asks the community for funding. Challengefunding has the community pledge funds upfront and requires a challengee to do something before funds are released. More info about my platform, Coindeo, can be found here:

My platform also allows the funds to be directed to a third party like a charity, so the Ice bucket challenge is an example where people could have used Coindeo to incentivize a celebrity to participate in the challenge. I believe that platform can create interesting social dynamics like how much is it worth someone's time to create a video for charity (and the community) when there is a guaranteed amount of BTC waiting to be donated.

Currently, the platform uses Twitter to create bounties, so to participate in this round of testing you'll need a Twitter account. Coindeo itself does not require account creation nor does it require you to "Sign in with Twitter".

For this round of testing, I'll fund the first 25 people that upload video of a noob using bitcoin for the first time. Just reply to this thread with your Twitter handle and I'll send you a challenge over Twitter. Here's what you'll need to do in order to claim your bounty:

1) Tweet "address <your btc address>" to @coindeobot
2) Send a Direct Message (DM) to @coindeobot with the text: "claimBounty BOUNTY_NUMBER CLAIMCODE". BOUNTY_NUMBER is assigned to you after I send you a challenge. A link to the bounty details will be sent to you in a tweet. CLAIMCODE is an arbitrary code that you create in order to claim the bounty (must be 8 or more characters).
3) Upload your video. Goto, enter your claim code and upload your video.
4) Wait for video to be approved. @coindeobot will tweet you when your video has been approved.
5) Retweet the "video accepted" tweet.
6) Wait for funds to be release.

Additional information about claiming your bounty challenge can be found here:

If you'd like to help test the donation feature, please include the charity's Twitter handle. In addition to the funds being donated to your charity, I'll also changetip you 0.02 BTC after your video is approved.

Let me know if you have any questions.

2  Bitcoin / Project Development / [BETA TEST] Coindeo (Crowdfunding for videos): 0.02 BTC for testing on: November 19, 2014, 09:46:04 PM
Edit 2014-02-10
I've made some exciting changes to Coindeo. Coindeo now allows you to challenge other people on Twitter to create videos for (crowdfunded) bitcoin. Let's say you want to challenge your friend to make a video of himself shaving his head. You create a challenge bounty and you and anyone else can fund the bounty. It's up to your friend to decide whether or not he will accept the challenge and for how much. Obviously, the more more funding that goes into the bounty the greater the incentive for your friend to shave his head.

A historical example of how this platform could have been used is for the Ice Bucket challenge where people challenged celebrities to dump a bucket of ice water on their heads for charity. Coindeo's new challenge bounty allows you to challenge someone to make a video and redirect the payment to a third party, such as a charity. I think this is an awesome feature and will be interesting to see how people decide what is worth their time to create a video for charity.

All of the original gaming video bounty features are still present and have been renamed to "self-created" bounties.

Similar to the last round, I'll be contributing 0.02 BTC to new challenge bounties (first 20 unique recipients only). Note, the recipient of the funds must have a Twitter account with activity more than 60 days ago. The How To has been updated and is still located at Or use the Tweet builder at

As usual, any feedback is appreciated.


Hi All,

  I've spent the last few months working on a project that I think could help with Bitcoin adoption. It's essentially a micro crowdfunding platform for gamers, game casters, and people that like to watch game play. Since gaming is a multi-billion dollar international industry and watching "e-sports" is on the rise (e.g., I think there is great potential for this project.

  I believe this project works regardless of Bitcoin use ó it's a great space even for traditional payment systems/currencies. In fact, friends have told me that I should not focus on Bitcoin use, but should accept traditional forms of payment. That is something I may do in the future, but for now this project is an experiment to see if the idea is viable.

What is Coindeo?

  Coindeo is a crowdfunding platform that enables you to receive up-front payments for producing video content. With Coindeo, you specify a minimum funding target then let your fans fund your video creation. Instead of waiting for a slow trickle of video advertising payments you get paid in full shortly after your video is uploaded. The platform helps you partner with your Twitter followers (and other fans) so you can deliver quality content without needing to worry about the cost benefits of creating content that your fans won't watch.

  Users tweet commands at @coindeobot to set up bounties (Eventually, I'll have a nice UI to help users craft commands). By using Twitter, users let their followers know that a bounty has been created and can go to Coindeo's website to request a deposit address to fund the bounty.

  Coindeo does not charge a fee on the bounty (at least not currently). However, when users upload a video, they grant Coindeo all rights on the video and agree to let Coindeo receive ad revenue from the video.

More details about Coindeo and how to use it can be found at:

  At the moment, I've put the platform on TestNet for alpha testing and would love to get any feedback about it. Admittedly, I've spent most of my time on the backend, so the frontend/UI is not really polished (lots of raw data). My initial goal is to focus on stability and robustness before opening up to a broader audience.  So please donít be too harsh with your critique of the UI Wink I know there is a lot to be desired on that front.

No new account creation or email address is needed to use the platform. Simply using your existing Twitter account to tweet at @coindeobot and use to browse bounties and get deposit addresses.

Feel free to send an email if you have any questions or would like more info.

3  Bitcoin / Mining speculation / What's the lower bound on mining hardware over the next year? ($/GH) on: September 02, 2013, 10:03:04 AM
At current prices, soon (or already) mining hardware will become unprofitable and hardware companies will need to lower their costs prices. What do you think the lower bound will be in the next year or so?
4  Bitcoin / Mining speculation / Will August bring an additional 200TH? on: July 17, 2013, 06:57:01 PM
Let's take a look at what's coming online soon:

Who                     Hash Rate   Notes
100TH70-100Initial rollout of 70TH at the end of July followed by 30TH
Avalon Batch #3~50TH600 units @ ~82GH = 50TH
Avalon Trade-in20TH?Unknown. Guesstimate 20th...should be more
ASICMINER new Blade+USB 15TH?No idea???
ASICMINER solo mining   15TH?No idea???
BFL30THLet's give them the benefit of the doubt and say they ship 500 singles worth of orders for the month. They claim ability to ship 3-400 units combined models a DAY

Lower bound: 70+50+20+15+15+30 = 180TH
More likely: 100+50+20+15+15+30 = 210TH

If someone has better guesstimates about what ASICMINER is going to do, I'd be interested in those numbers.

The bloodbath coming in the fall is going to be even worse Tongue
5  Economy / Auctions / [WTS] IN-HAND Batch #1 Avalon for local pickup on: June 11, 2013, 08:14:53 PM
xpost from the Goods section since people seem to look to the auctions subforum for avalons.

Here are the pictures and posts when I first got my avalon:

The machine works great and runs super stable.

Looking for 270 BTC. Price cut. Starting bid 230 BTC.

Prefer local pick up in Northern California (bay area). If no one local wants to buy, I'll consider the next best offer.

For your reference:
ASICMINER blades are priced at 50BTC per 10-13GH
This Batch #1 just sold for 281 BTC:

from yifu: no avalon batch 4. avalon will focus on selling chips and developing gen2 (don't know if they will sell units). SMT line should be up in a week. batch #3 will follow quickly behind batch #2.

from josh: BFL mini rigs will probably be split into 3 units of 500GH/s. They will start sell 500GH/s units...maybe in the next 2 weeks. Power consumption of the 500GH/s units are currently ~3kW. Trying to get near 1.5kW.s

8  Bitcoin / Development & Technical Discussion / What (if any) mechanism is there to protect against a massive hash rate drop? on: April 22, 2013, 10:25:51 PM
If you're unaware, Terracoin had a problem a couple weeks ago with ASICs shooting up their diff then leaving the network (thus leaving the network at a very high difficulty relative to remaining hashing power). I think NMC had the same problem and it was resolved with merged mining, but that effectively killed NMC(??).

I wanted to ask what mechanisms in BTC there are (or can be) to prevent a massive hash rate drop off. Right now, we have some massive amounts of hashing power being generated by Avalon and ASICMINER. If there was a bug in their firmware  (e.g. the recent large coinbase bug that dropped all avalons on eligius to 0 MHS) that caused all Avalons or AMs to drop off the network temporarily or permanently, it could take days for a new block to be found. This would wreak havoc on the entire bitcoin ecosystem by bringing transactions to a standstill.

Of course, as more manufacturers produce ASICs this problem is reduced, but let's say BFL delivers and their customers end up being 30% of the network...we'd still have the same problem. (We're all very confident in BFL's ability to produce a quality product  Grin)

Is this a legit concern? Shoot me down. I'll feel better.
9  Economy / Auctions / [WTS] Batch #1 Avalon. AVAILABLE NOW. Local pick up only. on: April 20, 2013, 11:13:53 PM
Auctioning a batch #1 Avalon.

Starting bid is at 300 BTC (bitcoin only. no cash). But it now price is 500 BTC.

This auction is for LOCAL pick up ONLY. Silicon Valley, California.

I will NOT SHIP.

Auction ends Monday April 22 6pm PDT. This is a quick auction. If no one bids, I will keep on mining with it.

Conditions: We meet at a pre-arranged safe location. You can verify that it works. Either you or I can bring the networking equipment to test it.

The unit is available immediately. After you transfer the BTC and 3 confirmations, the unit is yours. The machine is in perfect working order, but if you have technical issues in the future, you must deal directly with Avalon.

Pictures of my unit can be found here:

12  Other / Beginners & Help / memory doesn't stay underclocked when under load on: July 22, 2011, 10:26:47 AM

I'm using MSI Afterburner to tweak my 2x6950 set up. I've used it to underclock my memory to 625Mhz...However, the MSI hardware monitor shows that the clock jumps back up to 1250 once I start mining. When idle, it shows the mem speed at 150Mhz (presumably the GPU is  in energy saving mode).  I know that Afterburner is doing something when I tweak my cards to 625Mhz since GPU-Z shows the change.

I've also tried Saphire Trixx, but that utility appears to be a bit buggy with my dual gpu setup.

Those that are underclocking your memory: does MSI's hardware monitor show your memory speed jump up when under load too? Anyone know how to keep mem speeds low while under load...or am I doing something wrong?
