1  Economy / Goods / Would members here be interested in buying High End Car Audio with Bitcoin? on: November 25, 2014, 02:32:31 AM
Hi, my local car audio shop is considering accepting Bitcoin for purchases. The owner asked me to see if I thought members here or other people online would be interested in this payment option on his website. I told him I thought it was a great idea, but I would check on other people's thoughts.

Any comments would be greatly accepted.

Here is a video of his store.....

3  Bitcoin / Mining support / Need assistance with keeping an AP/Ethernet bridge connected (0.05btc Reward) on: October 10, 2014, 09:21:13 PM
I have a new Edimax EW‑7228APn which can be set for Wifi Repeater or Access Point(Ethernet bridge). I am using it as an Ethernet bridge for miners on a raspberry pi to connect to my dlink router. I set it according to set up disk and it only stays connected for a few hours before it drops connection until you restart it.

My dlink router is 192.168.1.1  (I have other wireless miners some are DHCP some static that work great connected to dlink)

Edimax came set 192.168.2.1

I changed Edimax it to 192.168.1.2 and also tried 192.168.1.245 (I think the problem may be here)

My miners on the raspberry pi are set to 192.168.1.97 static (the pi connects via Ethernet cable to Edimax and then wireless to dlink router)

Like I said the Edimax drops signal every few hours requiring a hard reset.

Any help would be appreciated. I do have basic networking experience, I'm just stuck on this one. Thanks

Note: Edimax is just one room over from dlink router.

Reward 0.05BTC for member who gets me going stable.

5  Bitcoin / Bitcoin Wallet for Android / How to sign message using android bitcoin wallet address..... on: September 16, 2014, 05:49:41 PM
The title says it all. I only use my HTC Android phone, no computers except pi's for miners. I need to know how to sign a message using my android bitcoin wallet address on my phone.

Thanks

I have found myself reading a lot of gmaxwell posts lately. His posts remind me of two hippies I saw arguing for hours about the difference between minimalizm and simple-izm years ago when I was stationed in Virginia while enlisted in the US Navy.

The problem is gmaxwell is a very smart guy and I'm nowhere near his knowledge level. I've found myself having to stay up several extra hours at night redeploying in education and trying to learn math and theory so I can somewhat understand some of his technical discussions.

Don't get me wrong, I'm not some crazy fanboy or something. I just can't stop researching some of the topics he goes deep into. Does anyone else have mods or other members that they like reading?

Here is a typical example of his posting:

"Yes, check out the recent paper on  "Scalable Zero Knowledge via Cycles of Elliptic Curves": http://eprint.iacr.org/2014/595

Which is a pretty wild technique.  Basically they managed (through an enormous amount of computation) to find a pair of pairing-compatible elliptic curves such that the number of points on one is the size of the finite field the other is defined over, and vice versa.

What this means is that in a ZKP written using curve A it's cheap to run the verifier for ZKP written in curve B. And for ZKP in curve B its cheap to verify proofs for curve A.

They take this structure and write proofs of the form "Verify a ZKP in the other curve of the machine state;  Execute one more instruction on top of that state.". Then they alternate these constructions, allowing for completely linear scaling.

The downside is that this magical stunt requires they use curves where the ultimate verifier (not insider a proof but on a computer) is a far bit slower. It also only allows for 80 bit security (The size ratios make achieving 128 bit security much harder). It also only helps for problems that work by repeated application of a universal circuit, like running tinyram, rather than running a hard wired application specific circuit— which many applications will have preferred for performance."  ~gmaxwell
