Data Management, Federation, and Coinstar for Coffee Beans

Follow the link for a roundup of technical updates and news from the past couple of weeks.

Technically, some highlights are:

• the ability to attach any key/value pair to a Stellar network account. Using the manage data operation, the account can have an associated encryption key, publicly attest to some fact, or provide other metadata about itself.
• Stellar.org dev Bartek also built a prototype of a Go cold wallet designed for Raspberry Pi. (If you give it a try, please be sure to attempt transactions on the testnet first).
  

For broader ecosystem news, check out Stellar integrator bext360's proposal for Ideo.org's Open Challenge: Stellar-powered smart coffee kiosks that automatically pay out farmers in the Democratic Republic of Congo. Each kiosk, which functions like a Coinstar for coffee beans, will serve around 4,000 farmers.
