Carrot

• 

  I could lift more, I know.

Inspiration

I wanted to do something involving bitcoin and had some arduino sensors laying around that I hadn't played with yet.

What it does

The user sets a goal for a number of reps(push ups) they want to do. They lock away some of their money in a 2 of 2 multi-sig address and wear a myoware sensor. When the sensor recogonizes they've hit their goal the program signs the multisig address releasing the funds back to the user.

How I built it

I used pybitcointools the blockchain.info api and arduino to build it.

Challenges I ran into

Crypto on arduino's is impossible(pretty much), wasted a few hours, had to do the hashing on the computer.

Accomplishments that I'm proud of

finishing. learning how to make a multisig "wallet"

What I learned

Bitcoin programming. arduino.

What's next for Carrot

A pretty UI.
